How to make a hole in the wall if there was no drill at hand

How to make a hole in the concrete wall if there is no peorator?

In the life of every person there are situations when you need to hang a picture, lamp, shelf, or something else. And if there is no pedorator, then the question arises: how to do this and it makes sense to spend money on this apparatus, taking into account the fact that perhaps the next time it will not be useful too soon. You can torment a poor drill for a long time or ask for a peorator from friends, neighbors or relatives. Consider also some other interesting options.

What experts are talking about?

There is no doubt that concrete designs are strong enough and it is difficult to drill them. It is worth adding to this that you can stumble on crushed stone, which enters the concrete mixture, from which the slabs are made just.

You can solve the issue of drilling holes in the following ways:

• using a drill that has a shock function using a winning drill;
• Another method is drilling with a diamond, however, it is necessary to be extremely careful here so as not to break the entire wall.

It must be said right away that it is quite difficult to make a hole in the concrete wall with a simple drill, so at the beginning of the work it is worth buying special drills with plates, which are made of winning, that is, material that copes with concrete and brick. In working with soft materials, such drills should not be used, since they will simply turn them into a baby, and not be cut.

Help to the home master

If you need to drill a small number of holes, you can use a drill that does not have a shock function. In the case when the walls of the wall are dense on, it is necessary to crush it with a punch. a storm made of solid metal equal to the diameter of the future hole. At such a moment, you need to insert a punch into the hole and beat with a hammer on it, while trying to crush complex areas and increase the hole deep into the hole. You need to periodically turn the pin. Then it is necessary to continue to work with an unstressed drill.

All these actions should be done until the very moment until the hole becomes the necessary depth. The described method is undoubtedly quite complicated, as well as tedious, but if you want to make a couple of holes in the wall, then it will be suitable.

A different option for drilling

Another option should be considered to be drilling concrete using universal drills that have diamond spraying. They have good efficiency when working with a wide variety of durable materials. You can install them on a simple electric drill, as well as on any other tool with a disabled vibration function.

With a drill it is worth working extremely carefully, otherwise it will break quickly enough. The drill tip should be periodically wetted so that it does not smoke and does not completely out of order.

Thus, in order to engage in drilling holes without the use of a pedorator, you need a drill that has a shock function, it is also worth it to stock up on the winning tips. The diameter of the holes when drilling a drill should not be more than 12 millimeters in diameter.

I would like to wish success in repairs!

A little about the device of the drill and install the drill

The classic drill consists of a power cable, buttons, capacitor wires, reverse, brushes and springs, anchor, stator, gearbox and cartridge, bearings, key and mounting screws. Properly inserted drill improves the quality of drilling, and can protect it.

The first thing to check, starting work with a drill, is there any pollution on the drill itself. In cleaning the drill, a beautiful assistant will be a rag. If the drill is weak, then there is a risk that it will fly out and injure the master. Accordingly, it is necessary to plunge the drill as much as possible into the cartridge (until it stops!).

In no case do not try to “lengthen” the drill through incomplete immersion in the cartridge!

It is important to ensure that the drill in the tool is fixed strictly along the axis. In case of non.compliance with this rule, drilling in concrete will be carried out poorly, the shape of the hole can be unpredictable, and the cause of all these misunderstandings will be the elementary effect of beating the drill.

Reasons for the dismantling and conditions for their conduct

Concrete structures are most often demolished when they served their term or began to collapse due to technogenic disasters, natural disasters. But there are other reasons because of which sometimes it is necessary to destroy quite strong constructions.

• Cleaning the territory for new construction.
• Demolition of structures erected without a project or with a violation of technology, and pose a danger.
• Redevelopment, reconstruction of buildings and communications.
• Dismantling of old objects that do not fit into the landscape.

Since it is not always possible to break concrete without prolonged noise, strong vibration, dust and garbage, dismantling work can cause serious inconvenience to people at home, neighbors. And when demolishing large objects, nature suffers and nearby buildings.

To minimize these negative consequences and avoid conflicts, in each case you need to try to choose the optimal ways of destruction. They are mechanical, thermal, chemical. We will not consider explosives, since their use by private individuals is illegal.

The above methods of destruction to varying degrees are effective. They are used in construction, although there are other possibilities for dismantling. With the help of various means, you will be able to eliminate old concrete products in a short time and take new.

It can be argued that now there is no universal method for dismantling concrete structures. You should choose the means and tools depending on the circumstances.

How to prepare high.quality concrete and pour the foundation for them, many know. But sometimes it becomes necessary to destroy concrete. This can be caused by the removal of part of the old foundation, the demolition of the old house and the redevelopment of the site for a new and a number of other reasons.

To destroy concrete, you can use a peorator, sledgehammer or soldering lamp.

Non.specialized information

Consider quite often used methods, which will provide help to realize how to destroy the cement foundation with your own hands:

Tip: when dismantling, the FRC is well helped by cutting reinforced concrete with diamond circles of the desired density.

In order to understand which method is suitable for a certain case, you need to get acquainted with each more detail.

Simple mechanical methods

The methods of destruction of concrete with the help of mechanical means are economical, accessible, however, in some cases, require significant time to obtain the necessary effect:

• The effectiveness of the application of a sledgehammer or a powerful peorator depends on the physical preparation of the worker, which is destroyed by the structure;
• The use of water and a soldering lamp allows you to gradually destroy the material by local surface heating and watering it with chilled water. After a few heating cycles, a network of cracks will appear, which can be easily cope with using a sledgehammer or a jackhammer;
• The use of a diamond tool has proven itself positively when working with reinforced concrete structures, regardless of their size;
• the execution of a group of holes into which the acute peak is driven from the peorator allows you to break large pieces from a concrete monolith;

Mechanically, the concrete product is destroyed by pieces using a sledgehammer

• The gradual moisture of wooden plugs inserted into the openings located according to a certain configuration allows you to split the monolith after their expansion. Expanding to 15% of its own volume, wood breaks concrete blocks along the required line, however, to obtain the effect, it is necessary for at least 10 days.

These are the mechanical methods of destruction, requiring significant physical training of personnel and time to achieve the desired effect.

Chemical methods for destroying concrete and reinforced concrete structures (ZhBK)

The acid method is based on the use of a mixture of hydrochloric acid of high concentration and inhibitors. Concentrated acid, penetrating deeper into the concrete massif, dissolves concrete, and special inhibitors enhance the aggressiveness of the solution and help to penetrate inside. The processed surface may not soften enough at once and acid treatment can be repeated.

The process of destroying concrete structures using the NRS-1 powder uses the property of a significant increase in its own volume as it freezes. In an unexpressive destructive agent (HCS-1), the main component is calcium oxide: its percentage in the suspension determines the speed of destruction of the structure. The deaf sputs prepared in a concrete mass are filled with wet mass of powder: the distance between the spurs also affects the time of loosening the structure to the desired degree. Thorough following the manufacturer’s instructions will easily get the planned result.

The technology for using the Powder “Quiet Explosion” is similar to the HP-1. The production of spurs and the manufacture of the mixture are available in the instructions of the manufacturer of the chemical drug NPO Stream. The effectiveness of the use of technology depends on the meticulousness of the recommendations. The main difference between the quiet explosion from HP-1 is the requirement to comply with the rules of working with aggressive environments, since the powder has a strong alkaline character: when preparing and laying in a spray, it can be harmful. Before and after applying the “quiet explosion” environmentally friendly and safe.

Methods of chemical destruction of concrete structures have a number of advantages, allowing:

• dismantle structures in a residential area without the use of heavy equipment;
• to disassemble part of the communications and buildings without stopping the current object;
• make work without creating vibrations, noise and dust;
• For destruction, there is no need to bring sources of electricity or compressed air;
• construction garbage and fragments obtained as a result of dismantling are easily disposed of.

From the shortcomings of the use of the NRS-1 powder, the “quiet explosion” and other analogues can be called an expensive price. In addition, they are delivered in large batches and have a limited shelf life without loss of effectiveness. Due to such shortcomings, powder is not suitable for ordinary consumer. For the acidic method, as well as for some ANAS-1 analogues, the main drawback is the mixture dangerous for personnel, the treatment of which requires carefully observing safety precautions when working with concentrated acids.

How to destroy the ZHBK with your own hands at home

All the methods of destruction of concrete described above can be quite applicable at home. Now there is no shortage of offers for renting disk and cable saws, jackhaled hammers, powerful peorators, and with sufficient perseverance you can also get an ultrasound device. Hydraulic installations with wedges of different sizes are also quite compact and affordable. No problems and chemical materials. With the appropriate budget and perseverance, any of these methods are realized.

However, if there is a desire to work with your own hands, there is a method from camnetans of antiquity:

• At a short distance from each other, the holes in the concrete array are drilled with a peorator.
• Clines from oak or other hard dry wood are tightened in the holes.
• Then the constant wetting of wedges from plastic bottles or hose with holes is organized by constant wetting.
• Wooden wedges swell and tear concrete.
• To break a significant piece, a couple of weeks will leave.

The best home set of tools for destroying concrete is a soldering lamp, sledgehammer, angular grinder and source of cold water. This method is the best in both the costs of physical energy, and in cost, and in the speed of solving the problem.

The main methods of concrete destruction

How to prepare high.quality concrete and pour the foundation for them, many know. But sometimes it becomes necessary to destroy concrete. This can be caused by the removal of part of the old foundation, the demolition of the old house and the redevelopment of the site for a new and a number of other reasons.

To destroy concrete, you can use a peorator, sledgehammer or soldering lamp.

Methods and their characteristics

The destruction of concrete is carried out in 2 ways:

Before destroying concrete, t.e. To decide on the method of dismantling, it is recommended to make sure that violation of the integrity of the structure will not entail other problems. For example, a bearing wall cannot be demolished.

A simple way

A small concrete block can be broken using a hammer or sledgehammer.

If the work area is large, the peorator will help to facilitate the work. The shock-revolutionary movements of the instrument violate the integrity of the design on their own, t.e. a person is not required to make additional efforts. It is enough to turn on and hold the tool in your hands.

If there is no pedorator, before breaking the concrete plate (uninhabited), several holes can be made in it (throughout the area). To perform this work, a drill and a drill (a concrete drill) will be required). Holes will weaken the strength of the structure, and it can be broken.

When you need to break the plate along a given path, you should make several holes in it (along the line where there should be a break). Wood plugs are inserted into the holes and begin to water them. As they moisturize, the material will begin to expand, which will lead to a violation of the integrity of the plate.

With the help of powder

A silent and physically simple method of destruction is the use of the powder product HP-1. In the destroyed structure, it is necessary to drill a hole, the diameter of which will be about 8 cm. Holes should be located at a distance of about 55 cm.

Acidic mixture

DISRIENCED DIY DIY METHERS SEARS IN THE PROPECTION OF Special acidic mixtures. They corrode material. They include concentrated acids and substances that allow preventing the destruction of other materials. For this reason, it is not recommended to use acids without inhibitors.

The dismantled area is watered with an acid mixture and wait for the chemical composition to dissolve concrete.

When it may be required to cut or cut?

Concrete blocks are produced in standard sizes and the building materials market rarely concentrates attention on selling something not standard.

In the construction process, the master understands that it is required to find such a block that could finish the masonry in a certain place, while the standard material here will not work. In such a situation, you have to resort to a cut of block concrete material.

If concrete blocks of non.standard size are necessary in large quantities, then it is better to cast them yourself using homemade forms. You can also order non-standard blocks from the manufacturer, but this will cost more.

Often, the builder may need half or a quarter from a whole concrete unit. Then it is necessary to make a cut.

Similar situations often happen when pouring a strip foundation, when all blocks should be of the same size, and when it is completed, several elements are not enough for its arrangement. The same situation may arise during the construction of the building according to the established project, when the wall thickness is already clearly spelled out and it is impossible to retreat from the values.

Often, when laying the corners, it is not possible to correctly enter the concrete block and the cracks between the stones remain. Many builders fill them with fragments of the material, which is also not completely true. In this case, it is recommended to pay attention to the tools and methods that can quickly and easily cut the concrete block material.

How and what is better to cut. the main methods

At the moment, by experimental experiments, several methods of cutting a concrete block have been established. This includes a manual method where you can use an angular grinder, wedges, codes, as well as a method in which specialized technology is used. Each of the methods requires a detailed consideration.

Manual method

The use of the manual method of sawing involves the absence of automated equipment, the master will have to cut the block with his own hands.

To do this, use it:

It is impossible to break or split even the most lightweight concrete block. The material has a good margin of strength, so you can not do without the use of auxiliary tools.

The manual method is chosen when the entrance of special equipment to the site is impossible due to obstacles. This technique is also suitable if it is necessary to cut a small amount of block material and call the team of workers with equipment costly and does not make sense.

Creaming a corner grinder

The first and most relevant method is working with a corner grinder. It is known that with the help of this tool you can easily cut foam concrete, aerated concrete and other light materials.

But whether the corner grinder will cope with the concrete block? To do this, you need to choose a powerful power tool. it must be completely serviceable.

Before starting work, it is recommended to take care of personal protective equipment.

It is worth buying a gas mask or a respirator in advance, you can use building gloves. The use of glasses will be a mandatory point: fine dust from concrete will fly in all directions and may be in the eye.

You need to choose a good cutting disk for a corner grinder. Since concrete is considered a strong material, it is difficult to work with it. For the saw, it is better to use a diamond disk. They are segmented, continuous and combined.

The segment is not suitable for such a durable material, and is continuous heated during the cut and it should be watered with water. It is better to purchase a combined diamond disk for a concrete unit cut.

It is important to find out if there are reinforced rods in the concrete block. If the cutter of the disk stumbles on them during operation, a failure may occur. Therefore, it is better to choose turbocharged discs if the thickness of the block is more than 10 cm.

When all the tools are ready, you can start work:

• Marking. Before making a cut, it is necessary to make a line of the line where the cut will pass. It is better to do this with a contrasting marker, so that even with glasses the master can be seen for a trimmer. So that the trimmer fishing line is perfectly even, along it you can put a wooden block.
• Incision. After turning on the corner grinder, it is necessary to make a cut with a depth of 0.5-1 cm.
• Cut. After that, the bar is removed and begin to carry out a cutting disk deeper. So far, it is not possible to completely cut the concrete block. If the tool is heated a lot, it is necessary to make stops and breaks for several minutes. Most likely, the cutting disk will also heat up: it can be periodically watered with cold water with a thin stream.

The advantage of this method is speed and minimum of effort, as well as the ability to cut even those blocks inside which there are reinforcement from metal.

The split with wedges

You can cut a foundation or wall block made of concrete using a split with wedges.

This method allows you not to hire specialized equipment and do it on your own, while saving money.

But there are disadvantages. the method is less accurate, and if technology is not observed, the unit is split diagonally.

In this case, the concrete block will become unsuitable for the goals of the master and will have to use another raw material.

To split with wedges, you need to prepare:

At the first stage, builders make markings, and it is necessary to do it along all the faces of the construction unit, regardless of its thickness. The marking should be clear, so it is best to use a ruler or a special long square.

Further, the peorator is taken for business: with this electrical tool, it is necessary to drill 7-10 holes along the marked line. You can only mark it on the side that is available, if possible, you can mark all sides.

Когда отверстия по 7 см глубиной высверлены в них вставляют металлические клинья. When buying wedges, it is worth considering that their end should be sharp. When the wedges are inserted, you need to score them a little inside with a sledgehammer.

As a result of the blows along the entire length of the marked line, a crack is formed. If everything is done using technology, then the crack will be even. The concrete block is split into 2 parts. At the final stage of work, builders using a sledgehammer and saw align the block so that it can be used as intended.

One of the disadvantages of this method is the duration of the procedure. Not every time it will be possible to get a perfectly even crack.

Shplintami split

Clicks are special pegs made of wood or metal. For the split of the concrete block, it is necessary to use wooden craps. This method works on the principle of expanding the material due to its wetting. To split the block, you need a peorator with a drill, marker for marking, wooden craps with a thin tip, as well as a sledgehammer.

• On the three sides of the concrete block, marking.
• With the help of a pedorator, holes are drilled about 7-10 pieces.
• Wooden codes are inserted into the holes.
• Clicks are watered with water.
• Когда шплинт набирает влагу он начинает размокать и набухать. As a result. the tree expands, from the inside it presses on the concrete block.
• The body of the block will be split in half.

Then, using a sledgehammer and saw, you can adjust the evenness of the surface of the block. The peculiarity of this method is that it is necessary to disperse holes exactly in the diameter of the Shplint, no more than.

Mechanical methods of destruction

If the concrete monolith of small sizes, it can be broken by a sledgehammer or a pedorator. This method is very difficult physically, in addition, for a large monolith, it is ineffective.

To destroy, you can use a combination of sledgehammer and peorator. Applying this method, the weakness of concrete to bends and breaks is used as much as possible. At a distance of 15-20 cm from the edge of a concrete monolith, a hole is drilled in concrete in concrete.

A pointed steel pin is inserted into this hole. a peak from a jack of a hammer or a piece of thick (at least 30 mm in diameter) reinforcement. According to the steel pin inserted into the hole, they hit with all its strength with a sledgehammer. A few strong blows are enough. and the concrete foundation begins to crack. If the concrete is not reinforced with reinforcement, then, having drilled several of these holes along the length of the concrete foundation and alternately exposing them to the strokes of the sledgehammer, you can break a fairly large piece of concrete monolith.

If there is a large supply of time and patience, then you can destroy concrete with a soldering lamp and cold water. First, the foundation section is heated strongly with a soldering lamp, and then watered with cold water.

After 3-4 repetitions, such a site will take a net of small cracks, and it will be enough a strong blow with a sledgehammer to crumble. The process of dismantling the foundation in this way can be stretched for weeks, or even months, but without any special costs and efforts, even a reinforced foundation will destroy.

The method of destroying concrete using wooden pegs is also effective. The as a pedorator exactly along the line of the intended chip in a step of 15-20 cm, holes with a diameter of at least 30 mm are drilled. In them, corks made of dry core of solid wood are clogged with a hammer. The traffic jams themselves should be a little larger than the diameter of the hole.

Drunk traffic jams are nourished with water to swell. To do this, pierce the bottom in a plastic bottle, then poured water into it and placed on a wooden plug. Under the influence of the dried up through the hole, the driven plug will increase to 15% of its original volume.

This expansion creates a pressure inside a monolith that can break even granite. This method is slow. so that a piece of concrete breaks, you need from 10 to 15 days. But he minimizes the physical efforts attached to destroy concrete.

If the concrete monolith is reinforced with a reinforcing mesh, then the peorator will not be able to drill a hole in it. In this case, you will need a special powerful drill with diamond nozzles. Such a drill will cut a concrete monolith of any thickness.

Chemical means of concrete destruction

Of the chemicals for these purposes, they most often use a special powder of NRS-1. With it, the process of dismantling the old foundation can be performed in 1-2 days. To use it in concrete, you also need to first drill holes. Then the water mixture is prepared: 1 kg of powder is added 0.27 liters of water.

The powder and water are mixed for 10 minutes, then the drilled holes are filled with the resulting solution to the edges. Continuing the reaction with water, the powder expands its volume several times, tearing the concrete. But its use has temperature boundaries, below which it cannot be used: from 5 to 30ºС.

It is important to remember that the higher the temperature, the colder the added water should be.

It will take less than a day and a minimum of physical effort to destroy concrete using HC-1. The only, but significant drawback is the high cost of powder.

To destroy particularly durable concrete structures, you can resort to the help of a special acid mixture. This mixture actually dissolves concrete, helping to clean bricks from it or remove surplus from the wall.

The composition of acidic mixtures includes concentrated acid, most often salt, and inhibitors. The latter are needed to protect other surfaces, such as brick or metal. The acid mixture penetrates deep into the concrete base and dissolves it, turning it into dust. But you need to use such mixtures very carefully using the maximum means for your own protection.

There are a lot of ways to destroy concrete, because not to break. not to build. The main thing is that this destruction occurs according to your desire, and is not caused by natural reasons, provoking the destruction of the built house.

In the song of the cartoon about Bremen musicians there are such words: “Our walls are pine giants”. But in reality, no one would like to live among such walls.

Therefore, so that after redevelopment of the room, the remaining walls do not collapse, and the residents did not have to live among the pines, it is important to put safety above their own preferences. The dismantling of walls and partitions should be legal and agreed with civil service.

We destroy reinforced concrete

The above methods of destruction of concrete in this case are not so effective. You will have to deal with the material that is much stronger. The use of the orator to make holes is simply pointless, so it is better to immediately prepare special devices. powerful drills with diamond nozzles.

Only such a tool can do such a job. In this case, you can drill holes at almost any angle.

Any methods of dismantling concrete structures described above are not able to oversee with a diamond harsh. The drill high strength of the material is not an obstacle, so it will cut any thickness.The price of the method is high, but it allows you to quickly cope with the task.

Tip: To cut a concrete block of large dimensions, you can use a machine with a diamond rope.

Only a professional can do work on it, since she has a rather complicated management. The principle of dismantling is the use of hydraulic pressure, after the block is wrapped in a rope. The cut rate directly depends on the strength of concrete. For example, in particularly difficult cases, about 2 m of the structure can be cut out in an hour.

At the same time, working with ordinary concrete does not cause difficulties. It is conducted 5 times faster. The machine is usually used for products with a thickness of more than 1 m.

During work, the following requirements must be observed:

• Constant cooling of the machine mechanism is required, since it heats up quickly from constant operation;
• Near the worker there should be source with cold running water. In addition, water also serves as a kind of protection of the diamond coating, preventing its destruction and washing off excess dust, which is formed in the process of work;
• you need to have a constant connection to three.phase voltage, otherwise the equipment will not work.

How to break through a concrete plug in the sewer?

Negligent builders drained the remains of the solution into the toilet and it froze. How to break through a concrete plug in the sewer?

The situation is extremely unpleasant and you will have to spoil in such cases certainly

It is necessary to disassemble the drain sewer, in another way it is impossible to eliminate such a defect. You can of course contact this company that carried out work and if you prove the guilt of the installers, they will simply change all the pipes to you. But I will say right away that it is a troublesome and long. Of course, according to a simplified scheme and without problems it is better to do it yourself. And for the future, monitor employees who drain the non.frozen solution into the sewer. You will have to disassemble the entire system to blockage and, together with the blockage, it is best to replace all the pipes, it is more reliable since it is possible that the solutions of the solution of the solution on which are subsequently clogged. Therefore, change all the pipes is so reliable and in the future it will be without problems.

Punch a plug from concrete, mechanically (for example, a plumbing cable) will not work.

There are special solvents (cleaners) for cement solutions on sale (concrete refers to them).

For example, such an EK 100 CypeP tool,

But if you have a PVC sewage system, this tool cannot be used categorically, moreover, if the PVC sewage system is lower than the floors of the neighbors, then in this case I do not advise using a solvent solventer for concrete.

If the sewage system is cast.iron, you can try.

Pour the product into the sewer, wait 10 minutes while it starts to act, then turn on warm water and rinse the system.

If the blockage remains, we repeat the procedure again.

If we are talking about PVC, sewage, then only the dismantling of a concrete site will help to correct the situation.

Back the sewage pipes, decide on the sound where in which area that very concrete cork (deaf sound, cork).

Next, we disassemble the sewer (it is baked, just remove one pipe from another).

In general, everything, you want to try to break through the pipe section, but most likely it will crack, so it’s easier and more correct to buy a new pipe and further installation in the reverse order.
