DRILLING OPENINGS

Diamond drilling is an effective way to create holes in reinforced concrete walls, ceilings and other structures. However, the method is limited by the size of the diamond drill - the largest bit has a diameter of ⌀450 mm. The method of drilling openings (perforation) solves this problem and is preferable when creating holes, the depth and dimensions of which exceed the capabilities of standard crowns.

Perforation is a common technique for making non-standard holes and openings in configuration and dimensions, when standard cutting techniques are not applicable. Diamond drilling of openings is a series of holes connected together to form the perimeter of an opening, which allows drilling a large segment of a building structure.

The cut out concrete fragment is subject to destruction by concrete breakers, hydro wedges, or lowered on hoists and disposed of. Depending on the type of opening to be created, the edges after diamond drilling can be processed with a saw or a jackhammer to form an even shape, i.e. a square or a circle.

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;
• 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 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 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 carried out, for example, to set up machines or fix supports to create a canopy, install 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 reinforced concrete of medium reinforcement (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

Dismantling reinforced concrete structures, it’s not an easy task, any builder who has come across 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 the 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 working process is carried out due to the diamond crown of the 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.

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. So best method considered diamond drilling. 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.

To negative aspects include expensive equipment for diamond drilling. 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 is calculated electrical wiring and sewer systems.
• 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. How bigger size a crown is required, the higher the price. Price for 1 cm drilling depth brick wall about 30 rubles less than concrete.

The highest rates for drilling holes custom sizes. In this case, several crowns are selected with different diameter and drilled in more than one step. If not consumable 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 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 technique 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.

Manual diamond cutting devices make holes in weakly reinforced materials, for example, cellular concrete and bricks. For reinforced concrete structures, wall saws are used, and the degree of reinforcement of the structure does not matter. diamond disc will cut through 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 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.

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 wear cutting tool higher, so the cost 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. diamond crown at the same time, it wears out more, and the speed of work is lower, so the cost of such drilling is usually higher.

Angle drilling video

Hole drilling

Often in force various reasons it is impossible to make an opening with 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.
