Installations of diamond drilling in reinforced concrete structures. Drilling and drilling in concrete

As you know, there are many ways to drill holes in concrete. Do not think that this is easy, and there are pitfalls here.

Difficulties most often do not arise when drilling small holes(up to 30 mm in diameter).

What you should pay attention to when drilling holes in concrete with a diameter of 30 mm or more:

Drilling of concrete indoors is carried out only with water supply, otherwise you will not be able to work due to the amount of dust. In addition, when cooled with water, the resource of the tool increases.

There are methods of percussive drilling (using a perforator) and non-percussive (using specialdrilling equipment). The impact method is more often used when drilling with victorious crowns; diamond crowns are always drilled in an unimpacted mode.

It is very IMPORTANT to know in advance whether you willdrill reinforced concrete , or ordinary concrete.

Drilling holes in reinforced concrete.

You can understand that in the process of drilling you came across metal fittings by the characteristic sound.

No need to try to drill reinforced concrete with a drill or carbide bits! The drill will simply burn out when it hits the rebar, the teeth of victorious crowns will fall off or break. In addition to spoiling more than one set of tools, you can also damage the electrical equipment on which you work: there are often cases when the gearbox crumbles on the hammer drill or the cartridge breaks when it hits the armature. But most importantly, you will uselessly spend your nerves, strength and time.

Therefore, it is possible to drill reinforced concrete onlydiamond crowns. Naturally, diamond crowns are an order of magnitude more expensive, but when drilling reinforced concrete with diamond crowns, the holes will turn out to be almost perfectly even (since drilling occurs without impact), and the process itselfreinforced concrete drilling happens very quickly. In addition, diamond drill bits have a much longer resource compared to carbide drill bits.

But still, the diamond tool has its own resource limitations. StroyDiam provides services forrestoration of diamond crowns. When restoring the crown, the edge is trimmed along with the old segments, and the new section is soldered new segments . How many times it will be possible to restore a particular bit for drilling reinforced concrete depends to a large extent on the professionalism of the operator.

When choosing diamond crowns fordrilling holes in reinforced concrete pay attention to the bond in the diamond segments, for reinforced concrete it should not be too hard.

Diamond drilling of concrete is widely used in construction. The technology has become popular due to its high efficiency. Since for the most part the supporting frame of modern building structures is monolithic reinforced concrete, other traditional drilling technologies under these conditions are inefficient. Even the most powerful rotary hammer cannot match this method.

To date, diamond drilling of holes in concrete remains the most effective for obtaining through or blind holes in reinforced concrete walls, and if they are saturated with reinforcement, the only way. In addition to concrete, this method can work with hard materials such as granite, marble, steel.

Advantages

Diamond drilling has many advantages over other methods:

• depth can reach 15 m;
• the ability to work at any angle;
• lack of dust and debris, which are completely deposited by water;
• the possibility of drilling, despite the location of the reinforcement;
• high speed;
• absolutely accurate and round holes with runout up to 2 mm and almost polished edges;
• low noise level during work;
• lack of vibrations that can lead to the appearance of microcracks;
• drilling is carried out in a vertical and horizontal surface;
• 220V power supply voltage is sufficient for work;
• can work in hard-to-reach places where traditional methods are difficult to apply.

The method also has its drawbacks:

• expensive equipment requires very careful handling and maintenance by an experienced specialist;
• consumables should be changed periodically;
• process cooling water flows onto the floor or wall and requires the use of additional water collection equipment.

Concrete diamond drilling technology

Drilling is carried out by a powerful unit, which consists of a base, a stand, an electric motor and a drill bit. Diamond teeth are soldered to the base of the crown. They

consist of crystals of industrial diamonds on a binder - powdered metal.

During drilling, under the influence of high temperatures, the crown is transformed into a monolithic matrix, which can quickly and efficiently drill in the toughest material: reinforced concrete and granite pass equally well. Moreover, it is possible to drill in brick, foam concrete and other traditional building materials. The speed of drilling and its great accuracy, with ideal positioning relative to the markup, the evenness of their geometric dimensions and other characteristics favorably distinguish diamond drilling from traditional, but outdated methods.

Diamond drilling is a non-impact method that compares favorably with jackhammers. To carry it out, it is enough to have at hand a regular household electrical network with a voltage of 220 volts and a source of water. The water cooling the working tool is collected immediately using an industrial vacuum cleaner.

Stages

1. The place of work, places of wiring of communications, electrical wiring, pipes, etc. are being studied.
2. Picked up optimal size crowns, the center and contours of the hole are determined.
3. The bed is attached.
4. An installation with a crown is mounted on the base.
5. The design is checked for play. The elements of fixation, fastening of the crown, carriage of the bed are inspected.
6. The water cooling system is supplied and connected.
7. Work is being done.

When may be required

Drilling with a diamond crown may be required both in an apartment of a multi-storey building and during the construction of a country cottage. The minimum level of noise and dynamic shock effects allow you to work in residential buildings during reconstruction and repair, and even in already renovated apartments. The technology can be applied to:

• drilling holes in the foundation for ventilation or sewerage;
• installation of gas and heating pipelines;
• power supply wiring;
• installation of fire fighting systems;
• air conditioning systems;
• mounting chemical anchors;
• conducting ventilation communications within the walls: pipes and sockets;
• fencing installation.
• other applications where precise, dust- and noise-free drilling is required.

The method is used when the task is to make a hole with an accuracy of up to a millimeter. Vertical holes are made, for example, to install machines or fix supports to create a canopy, installation garden furniture etc.

During the repair of residential apartments and offices, it is sometimes necessary to break through a new opening. During the repair process, sometimes it becomes necessary to change the layout, within which it is necessary to make a door or window opening. You can make a series of holes to form one large or even an opening of any shape.

Diamond drilling in concrete - prices

The price of diamond drilling depends on the diameter of the hole and its width. The cost is calculated in centimeters. The following factors also affect the cost of the order:

• drilling at height;
• on non-electrified objects;
• saturation of reinforced concrete with reinforcement;

and some other possible factors.

The cost of work is given for vertical drilling of medium-reinforced reinforced concrete (no more than two meshes of reinforcement with a diameter of up to 22 mm, with a mesh pitch of at least 150 mm), concrete grade 300, without water drainage.

The cost of the minimum departure is 4500.00 rubles.

Drilling multipliers

Diamond drilling in reinforced concrete — modern technology which is characterized by high efficiency of the work done. Cutting makes it possible to quickly and efficiently cut solid materials of any degree of reinforcement. Diamond drilling works are carried out when it is necessary to carry out ventilation, solve the problem of sewerage routes, and reconstruct living quarters in a short period of time. The excellent quality of the technology is incomparable with the work of a perforator or a jackhammer. Holes, boreholes, openings or recesses are accurate, even, smooth, characterized by a minimum presence of dust, noise and vibration waves. Specialized equipment will cut reinforced concrete and other materials in a few hours. Similar effect impossible to achieve using other tools and methods of work. The service of diamond drilling in Moscow is in great demand.

Features of the technological process

Diamond drilling of reinforced concrete structures is labor-intensive, requires thorough and in-depth knowledge, skills, experience, as well as specialized supplies. There are several methods for drilling reinforced concrete structures. The choice of method depends on the level of complexity of the work to be performed. At the moment, the most effective is cutting various materials. Process Benefits:

• A minimum noise level is produced that meets all sanitary standards, which in turn allows for the repair or construction of residential premises and industrial facilities.
• Good speed and powerful cutting allows you to effectively work on reinforced concrete structures.
• The high severity of the cut and the non-impact method minimize the presence of vibration waves and construction dust.

High process controllability. Cutting is used to create a smooth and even surface with little or no deviation from the markup.

High-tech equipment with diamond coating allows fast and high-quality drilling of reinforced concrete products. The technology prevents the formation of cracks on the surface, damage to engineering communications. Such troubles are inevitable when using the impact-dynamic method. Often, wall chips and deformation lead to partial or total destruction structures.

Service prices

Diamond drilling in concrete is one of the most effective ways and sometimes the only one. With it, through and blind holes are made in concrete, brick and reinforced concrete structures. It can also be used to process marble, granite and steel structures.

Making holes in the walls will come out in other ways, for example, with a drill and a puncher. But the first is only suitable for creating small holes, and the second may not be used in all cases. The puncher emits a strong vibration, and it is impossible to carry out such work in residential premises. The drill bit will quickly become dull in concrete when drilling deep holes, and the jackhammer will not be able to pierce the reinforcing bars. Therefore, diamond drilling is considered the best method. It is able to cope with any building material.

Positive traits:

• Possibility of drilling at an angle up to 45° and in hard-to-reach places.
• High speed.
• Obtaining precise and smooth holes in concrete that do not require additional processing.
• Absence of vibrations, which eliminates the possibility of cracks in concrete or other structures.
• Low level of emitted noise, thanks to which work can be carried out in residential buildings.
• Drilling is possible in both horizontal and vertical bases.
• A network with a voltage of 220 V is sufficient (not for all types).
• No dust (only for those cases where water is used).
• Ability to drill reinforced concrete structures.

The disadvantages include expensive equipment for diamond drilling holes. Only an experienced person should use this tool. It also requires frequent replacement of consumables. If water is used during drilling and no drainage system is installed, then all the dirt will flow along the walls and floor. For collection it is necessary to use an industrial vacuum cleaner.

Drilling is carried out with a device consisting of a base, rack, engine (electric, gasoline) and. Precise and even drilling is achieved thanks to the teeth on the crown, made of industrial diamond crystals. It equally easily drills both concrete and granite, and even more so gas and foam concrete or brick.

Stages of work:

• The area where it is necessary to drill concrete is being studied, or rather, the location of electrical wiring and sewer systems is calculated.
• Determine the location and select the diameter of the diamond crown.
• The frame and equipment are being installed.
• All tools are checked for play and fixation.
• Connects to the water supply system.
• A launch is made, and concrete drilling is started.

When might it be needed?

Diamond drilling technology is carried out in the following cases:

• Creation of openings for ventilation, sewage, and air conditioning.
• Installation of pipelines for water and gas.
• Installation of electrical wiring, fire protection system.
• Drilling for chemical anchors, sockets.

Average cost of work

The price of diamond drilling in concrete mainly depends on the diameter, number of holes and their depth. Other factors are also taken into account, such as the diameter of the drill. The larger the required crown, the higher the price. Price for 1 cm drilling depth brick wall about 30 rubles less than concrete.

The highest prices for drilling holes of non-standard sizes. In this case, several crowns with different diameters are selected and drilled in more than one stage. If not consumable the right size, you will have to order it and pay all its cost. Drilling structures with hydraulic equipment is even more expensive.

Before ordering such services, you should know what else can affect the cost of diamond drilling:

• drilling at height or in hard-to-reach places;
• creating holes at an angle;
• bad weather conditions.

Prices also increase if there is no source of water supply or electricity nearby.

The lowest prices are set for drilling holes for evaporator pipes - about 15 rubles per 1 cm or 1500 rubles per linear meter.

If drilling holes in concrete is carried out without the use of water in a residential area, then the entire room and furniture must be covered with plastic wrap. So it will be much easier and faster to remove all the dust.

Another advantage of diamond drilling compared to conventional methods is that holes are obtained exactly in size and with even walls. This method is especially relevant when it is necessary to prepare a place for the installation of equipment (machines, supports, etc.).

Hole cutting

If you need to make long strobes, openings for doors and windows, or expand old ones, remove defects, beams, diamond cutting is used. In this case, drilling takes place not with the help of a crown, but with a disk or a rope, hence the name - disk wall saws and wire rope machines, as well as joint cutters. Just like drilling machines, this technique does not create vibrations. It can also be used in the repair of residential buildings, the likelihood of cracks in walls made of concrete or other materials is completely excluded. The cut after diamond sawing is absolutely even and smooth, no additional processing of the edges is needed.

Depending on the power and purpose, the equipment has different sizes. There is a convenient compact, large equipment is not used in residential buildings, but only in the construction or repair of non-residential. Manage diamond cutting either manually or automatically. The second option provides complete safety for people, since no one is near the machine during operation. Hand saws are light in weight, so they can be easily operated by one person.

Joint cutters are used to create holes and strobes for laying various communications. No rail installation is required, which greatly simplifies the entire process and cutting time. Manually operated floor saws are only capable of cutting shallow depths, so there is no need to connect water to them. Automatic, on the contrary, make cuts larger than 12 cm, and necessarily require the supply of water for cooling. The second option is considered the best, since dust is not emitted during operation.

Hand-held diamond cutting devices make holes in weakly reinforced materials, such as cellular concrete and bricks. For reinforced concrete structures, wall saws are used, and the degree of reinforcement of the structure does not matter. The diamond blade will cut any base.

cutting brick construction will cost an average of 6,000 rubles per m2, monolithic reinforced concrete - from 10,000, cutting a reinforced opening - from 36,000. Wall chasing for electrical wiring also depends on the material: in brick - from 250, concrete - from 350, reinforced concrete - from 400 rubles per running meter.

Diamond drilling machine - one of the most durable and reliable diamond tools for core drilling of perfectly even holes and technological shafts in structures made of concrete and reinforced concrete, stone, brick, foam concrete and expanded clay concrete, such as: walls, floors, ceilings, foundations, runways, etc.

Diamond setting most widely used in the following industries: for laying pipes for water supply, heating, sewerage and other utilities; when installing cables, ventilation systems, air conditioners and hoods; for cutting openings in reinforced concrete, etc. In addition, buy diamond drilling rig reasonable for use when drilling cores in asphalt as well as hard rock in mines or face. Reconstruction of buildings, industrial dismantling, installation of chemical anchors, sampling of building materials at laboratory analysis- in all these processes the machine is used diamond drilling holes in concrete, which allows you to perform the work as quickly, efficiently and safely as possible.

Diamond drilling rig buy or not, what is the price?

Solving the question: Installation of a diamond drilling to buy or not? The answer is obvious - the machine diamond drilling holes in concrete makes holes of various diameters and depths in concrete, reinforced concrete and other hardest materials; during operation, it does not create strong vibration, which greatly simplifies the process of work, reduces the noise level, does not damage or chip the material being processed; there is no dust cloud. Diamond drilling rigs absolutely safe for the environment and human health, so they can be successfully used in residential areas. If you want all the resulting holes to be completely smooth, clean and do not need any additional processing at all, you must buy it! Price diamond drilling rigs may vary greatly depending on the brand, country of manufacture and specifications.

The design of the diamond drilling machine:

The diamond drilling rig is a powerful and heavy professional tool for drilling deep holes of medium and large diameters in high-strength materials, which consists of a motor, a stand and a set of additional equipment and tools (crowns, extensions, etc.). As a rule, a diamond drilling machine has in its design a mechanism for supplying water, which cools the segments and the crowns themselves, extending their service life. The diamond drilling rig can support both dry and wet type of drilling. A professional diamond drilling rig allows you to drill regardless of whether there is reinforcement in concrete or not. The difference in performance is only that with a large presence of reinforcement, the process will proceed somewhat more slowly, but the result will still be achieved.
