Concrete drilling technology

The technology for punching through holes in concrete is based on the use of special installations. The main elements of such an installation are a frame, a cooling system and a crown, which is driven by an electric motor. The crown is a cylindrical pipe, on the working end of which carbide cutting teeth coated with industrial diamonds are soldered.

Rotating at high speed, the crown bites into the rock. On work surface Water is constantly supplied, which cools the drilling machine and prevents the formation of dust. The longitudinal feed of the machine is provided by the drilling rig operator. As a result of drilling, a cylindrical core is cut out of the concrete, which is then removed.

Diamond tools have undeniable advantages:

Accuracy of work
equipment adjustments allow you to set the center of the hole with an accuracy of 1-2 mm;

Smooth edges
the resulting openings have a smooth inner surface, which does not require further processing;

Minimum noise
work can be performed in residential buildings and on commissioned objects;

Free from dust and dirt
the equipment operates without creating dust, we will ensure cleanliness at the site and remove construction waste.

Gentle and accurate drilling process

Impact tools subject building structures to heavy loads and serious vibrations.

Crowns carefully drill out a specified area in concrete walls ah without dust and damage. With their help, you can make holes without affecting the load-bearing elements.

Areas of use

Diamond drilling rigs are advisable to use during capital construction or repair of facilities. With their help, you can quickly and accurately make a through opening in a wall or ceiling, create an arch or niche, and remove excess material.

Quickly create openings in concrete for:

Plumbing, heating, sewerage

technology diamond drilling allows you to drill holes in concrete walls and ceilings, for pipelines of water supply, heating and sewerage systems. The high speed of obtaining openings significantly reduces the time required for installation of communications.

Power supply wires

concrete drilling equipment is used to lay cables electrical networks through partitions and ceilings. The machine can drill holes in concrete at any angle to the surface, which makes it possible to lay electric wires in an optimal way.

Channels for cables of information networks

With the help of concrete drilling equipment, installation of cable ducts and pulling cables for the Internet or TV are carried out in the shortest possible time. Drilling rigs operate neatly (without shocks and vibrations), which allows installation work to be carried out cable networks not only in new buildings, but also in buildings that have been commissioned.

Air conditioning and ventilation ducts

The diameter of cutting bits for diamond drilling reaches 500 millimeters. Crowns big size ideal for drilling holes for ventilation ducts and ductwork for high-performance air conditioning systems.

Drilling large diameter or deep holes

Our machines can drill concrete structures not only perpendicular to partitions and ceilings, but also at any angles other than 90º.

The crown movement speed is from 2 to 6 centimeters per minute. On average, through vents in floors and walls standard thickness done in 15-20 minutes. High performance and affordable prices, the main factor in construction work.

Diamond drilling concrete has become widespread in construction. The technology has become popular due to its high efficiency. Since for the most part load-bearing frame modern building structures is monolithic reinforced concrete, others traditional technologies drilling under these conditions is ineffective. Even the most powerful hammer drill cannot compare with this method.

Today, 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 be used to work with hard materials such as granite, marble, and steel.

Advantages

Diamond drilling has many advantages over other methods:

• depth can reach 15 m;
• possibility of working at any angle;
• absence of dust and debris that 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 2mm and almost polished edges;
• during work low level noise;
• absence of vibrations that can lead to microcracks;
• drilling is carried out in vertical and horizontal surfaces;
• 220V mains voltage is sufficient to carry out the work;
• you can work in hard to reach places where it is difficult to apply traditional methods.

This method also has its disadvantages:

• 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 along the wall and requires the use of additional drainage equipment.

Diamond drilling technology for concrete

Drilling is carried out by a powerful installation, 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 technical diamond crystals in a powdered metal binder.

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 are drilled 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 markings, the evenness of their geometric dimensions and other characteristics 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 outlet 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 location of the work, the location of communications, electrical wiring, pipes, etc. are being studied.
2. Selected optimal size crowns, the center and contours of the hole are determined.
3. The frame is attached.
4. An installation with a crown is mounted on the base.
5. The structure is checked for play. The fixing elements, crown fastening, and bed carriage are inspected.
6. The water cooling system is supplied and connected.
7. Work is being done.

When may it be required

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

• drilling holes in the foundation for ventilation or sewerage;
• installation of gas and heating pipelines;
• electrical wiring;
• installation of fire protection systems;
• air conditioning systems;
• installation of chemical anchors;
• installation of ventilation communications within the walls: pipes and sockets;
• installation of fences.
• other cases where precise drilling without dust and noise 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 secure supports to create a canopy, installation garden furniture etc.

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

Diamond drilling of holes in concrete - prices

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

Diamond drilling machine design:

The diamond drilling rig is powerful and heavy professional tool for drilling deep holes of medium and large diameter in high-strength materials, which consists of a motor, stand and set additional equipment and tools (crowns, extensions, etc.). Typically 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 drilling. Professional diamond drilling rig allows drilling to be carried out regardless of whether there is reinforcement in the concrete or not. The only difference in performance is that if there is a large presence of reinforcement, the process will proceed somewhat slower, but the result will still be achieved.
