Diamond drilling of concrete is widely used in construction. The technology became popular due to its high efficiency. Since for the most part the supporting frame of modern building structures is monolithic reinforced concrete, others traditional technologies drilling under these conditions is 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;
• water cooling the process 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 hardest 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 high 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of their geometric dimensions and other characteristics favorably distinguish diamond drilling from traditional, but outdated methods.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 also be required in an apartment high-rise building and during construction country cottage. The minimum level of noise and dynamic impact allows 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;
• installation of chemical anchors;
• conducting ventilation communications within the walls: pipes and sockets;
• fencing installation.
• other cases when required precise drilling without dust and noise.

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.

Diamond drilling rigs are designed for drilling holes in walls made of high-strength materials, marble, hard natural stone or reinforced concrete with a high degree of reinforcement. Drilling machines allow drilling not only on flat, but also on relief surfaces, at almost any angle. For cooling working surface crowns and processed material is used water.

Diamond drilling is characterized by a very low level of dynamic loads and vibration. Due to this, the structure of the material in which drilling is performed is not disturbed, and at the time of completion of the process, it is not damaged. exterior finish walls. After drilling, no extra cracks form in the wall, and the drilled core remains inside the crown and does not fall out into the street with the risk of falling into the hood of someone's car.

It takes 10-15 minutes to mount the drilling rig. The machine is fixed with anchor fasteners, or with the help of a vacuum plate, if it is not possible to use anchors. The material can be anything: brick, concrete or marble. A large number of reinforcement in the composition of reinforced concrete will not be able to interfere with drilling and will not affect the quality of the finished hole, but will only affect the total operating time. You can find out the cost of services on the page "Prices for diamond drilling".

Areas of use:

• holes in the walls for installing split systems
• openings for heating, water supply, sewerage risers
• air ducts, vents for natural ventilation premises
• alternative way making openings in walls
• alternative way to dismantle reinforced concrete structures

Technology advantages:

• high drilling speed
• high accuracy positioning
• low tool wear
• low energy and resource costs
• no damage to exterior walls
• no surface post-treatment required
• the core remains inside the bit, no debris
• minimum noise, dust and vibration

Dry diamond drilling

It is used where it is not possible to use water for cooling, for example, where there is a risk of flooding the lower floor, in rooms where Finishing work, next to the power grid. To collect dust, an industrial vacuum cleaner is connected to the drilling machine. With dry drilling, the speed of work is lower, and the wear of the cutting tool is higher, so the cost of work is higher.

Deep diamond drilling

Drilling machines allow you to drill holes up to several meters deep. First, a hole is drilled to the depth of the crown, the core is knocked out. Then a crown with an extension is installed, the core is knocked out again, another extension is installed. And so on, until the desired depth is reached.

Angle drilling

Holes can be drilled not only perpendicular to the surface, but also at an angle to it. At the same time, the diamond crown wears out more, and the speed of work is lower, so the cost of such drilling is usually higher.

Hole drilling

Often in force various reasons it is impossible to make an opening with help diamond cutting, For example:

• limited space
• low power electrical network at the facility
• lack of running water
• gouges from a large disc can change bearing capacity reinforced concrete structures
• large material thickness, with small opening sizes

In such cases, you can drill an opening around the perimeter with a diamond core bit.

The dismantling of reinforced concrete structures is not an easy task, any builder who has encountered this will tell you about it. In order to simplify the task, we use drilling machines for diamond drilling and drilling.

Diamond is one of the most durable minerals in nature, which is distinguished by its hardness and reliability. The diamond drilling rig, in turn, is the embodiment of the reliability of the diamond itself, which is supported by innovative developments and modern technologies.

Why is a diamond drilling rig better than other similar technologies

Diamond drilling is a material processing process that allows you to create holes in various building materials such as concrete, clay (brick), granite, a natural stone through the application diamond tools(diamond crowns).

The diamond drilling rig is technical device, carrying out drilling, drilling due to an electric or hydraulic motor and bed.

Such devices allow drilling in:

• concrete and reinforced concrete walls
• foundations
• ceramic tiles

Benefits of a concrete diamond drilling machine

• The workflow is much faster.
• Drilling tool, no vibrating waves, lower noise level
• Chips on the processed material are not formed;
• No dust. No cracks appear
• Less traumatic work
• The ability to make a hole in a hard-to-reach place.

Types of diamond drilling rigs

There are two types of diamond drilling machines.

• Dry drilling - this type of installation is used when working with soft materials such as brick, limestone, thermoblock and aerated concrete.
• With water supply. In this case, water is supplied to cutting tool, cooling the crowns, thereby increasing the service life. This method is most often used for high-strength materials such as natural stone, concrete and reinforced concrete.

Where is the diamond drilling machine used?

As mentioned earlier, the diamond drilling rig is used in construction and repair work, for drilling various designs and surfaces. The work process is carried out by diamond crown device. The hole diameter can vary from 12 mm to 600 mm. From this follows a different scope, depending on the specific need for operating the installation. Very often, such a development is used in the process of laying communications (pipes, ventilation, electrical cable and etc.). Sometimes diamond drilling is used to take samples, for example, of rocks or monolithic structures.
