Diamond wire for cutting reinforced concrete

Dismantling work concerning large-sized reinforced concrete structures is seriously complicated by their size and the strength of the material from which they are made. Wall cutting machines and especially hand cutters are useless here - something larger and more powerful is needed. It will help in this situation cutting with diamond tool

, namely a rope - it will cope perfectly even with capital structures more than a meter thick. The rope used in them is actually a cable, the individual segments of which are coated with diamond sputtering. It is pulled along the cutting line, resulting in a cut with beautiful and smooth edges that does not require additional processing. If increased cutting accuracy is required, instead of a rope, you can use a diamond string, which is much thinner.

Features of the method

To experience all the benefits of wire sawing.
Strict adherence to technology is required. For different types of materials, the speed of rotation of the cable is different, the lower the speed, the faster the rope wears out; if the speed is higher than that required for a given rock, the rope can become “soiled,” and in order to start working with this cable again, it must be re-opened, losing a lot of time. and rope resource.

The rope must be twisted.

Often our clients neglect curling or do not take it seriously. But the correct wear of the cable depends on the correct twisting, because if the cable is not worn evenly, you will also lose money later, because the rope will not exhaust its resource to the end.

Insufficient pressure

Often our clients, in order to achieve an increase in the life of the diamond wire, deliberately lower the productivity, but for proper opening of the rope, pressure is necessary. Therefore, at this point you should strictly follow the instructions.

What is a rope machine?

This is a very powerful, reliable, and at the same time quite compact unit. Its cutting element is a steel cable with an abrasive in the form of small diamond particles. This is the same diamond wire, its diameter is only 6 mm, and its length is as much as 60 meters. The technology is simple and consists of enveloping and then cutting an object with a loop of rope. Can such a thread cope with a concrete column!? No problem! Remember the old-fashioned way of cutting butter with a fishing line. Only the cutting speed can reach up to 8 m2 per hour. And the depth of the hole is limited by the length of the rope - 60 m!! And with such power and performance, there is no damage or deformation of surrounding objects.

Conditions required for work:

• Electricity 380V (or generator)
• Water supply to the cutting part of the rope. Water cools the heating elements and at the same time removes dust particles and crumbs from the cut.

What is the difference between diamond disc cutting and wire cutting?

1. Rope cutting is used when it is necessary to cut through a large stone block or concrete structure; the disk during operation will be limited by a flange, i.e. the maximum depth that the disk can cut is equal to the distance from the edge of the disk to the flange (usually the sawing depth of the disk is calculated using the formula: Disk diameter /3, calculating using this formula you will definitely not be mistaken in choosing the diameter of the disk).
2. Rope sawing requires less water than sawing with a disc.
3. If we compare sawing stone blocks, then disc sawing requires a more powerful motor, while cable sawing requires a less powerful motor. This is especially important if your workshop lacks power.
4. Disc sawing of blocks is noisier than wire sawing - this is especially important when your workshop is located next to a residential area.
5. Cost of tools for sawing 1 sq. meters with a rope Higher than sawing the same area with a disk.
6. When sawing with a large-diameter disk, the quality of the resulting workpiece is affected by the quality of the soldering - whether the slab will subsequently deviate and/or become defective depends on the qualifications of the solder and/or his mood. With rope cutting, this problem does not arise, because the operator is only required to “crimp” the rope according to the instructions and follow the technological regimes.
7. The accuracy of sawing with a disk is higher than the accuracy of sawing with a rope.
8. Rope cutting gives you the ability to cut curved shapes (if your machine allows it)

• The cost of an error:
  when your operator on a 3000 mm circular saw systematically violates the sawing technology, this can lead to deformation of the expensive disk body, and in the case of a rope, when it comes to single-rope sawing, when there is also a violation of the sawing technology, in the case of increased load on the cable - increased pressure (occurs when they try to saw faster than expected) - it breaks, but often it can be “crimped” (fused) again. (Help: a rope can break not only due to increased pressure, but this is a topic for another article). In addition, often the Workshop does not have its own shareholder, and when a segment on the disk body comes to an end, it is necessary to call a third-party specialist, who may be busy during the high season, and as a result, the machine may be “idle,” and in the case of a rope, this no problem arises.

What tools are required?

Wall sawing machines

Units of this type are an excellent tool for cutting concrete structures. The machine is equipped with a mount and rails for moving the saw, so it can perform a large amount of work without rest. In addition, using such a mechanism has the following advantages:

• increasing the depth of the opening to 7.5 cm;
• performing complex work on a large scale;
• low vibration and noise levels;
• possibility of fixing the machine;
• diamond cutting of reinforced concrete in the shortest possible time.

When cutting on such a machine, training courses are provided and access to a 380 W network is provided.

Manual equipment

A common tool among builders, it has a large range of sizes.
A grinder for cutting concrete of this type has replaceable discs that are attached to the unit using a screw device. The construction market offers a wide selection of equipment of various sizes and power. The depth of the cut hole reaches 13 cm. The hand cutter is easy to move from place to place and cut in hard-to-reach places. The disadvantages of such a device include the application of great effort on the part of workers, which reduces the volume and time of the continuous process.

Rope cutting

Such equipment is most often used on large construction sites, as it has a high cost. The cutting device is a diamond-coated rope that cuts concrete in any direction. This equipment is most often used to dismantle concrete on bridges, piers, columns or other large objects. The advantage of a cable cutter is that it is powered by a hydraulic or electric drive, which makes it possible to use the unit in places without access to electricity. The depth of the holes made by the diamond wire reaches half a meter.

Work as an angle grinder

Depending on the type of material, the worker selects the appropriate cutting wheel.
The tool is popular and necessary in every household. A concrete grinder cuts material 15 cm deep, and when accessing both sides of the structure, the thickness of the wall it cuts increases by 2 times. The device is quite mobile, so it provides access even to hard-to-reach areas. When cutting reinforced concrete structures, it is better to choose a saw without teeth, as they cling to the metal and the cutting element will be damaged. For regular concrete, serrated discs are also suitable.

Seam cutters

A similar device is designed for cutting seams on a horizontal plane. Professional equipment also has disadvantages. First of all, this is the high cost of tools and labor. The device is equipped with a motor and a cutting element, which can easily move along the floor using wheels. Depending on the thickness of the floors, the following 2 types of seam cutters are used:

• Stationary. Used for cutting thick layers of monolithic concrete.
• Portable. The depth of the incisions is no more than 2.7 cm.

Diamond saw cutting

The device is self-powered and provides dust-free operation.
Diamond cutting of concrete is often carried out on sites where there is no access to electricity. In such cases, a gas cutter is suitable. The saw is easy to use and makes right angle cuts. The appearance is similar to a wood chainsaw, but the chain stands out due to the complexity of the tires, which are equipped with water channels. This allows you to make dust-free cuts. Ease of operation allows you to use the equipment without special training, so a saw for cutting concrete of this type is used in DIY construction.

Diamond cutting of concrete

Why cut concrete at all?

When remodeling an apartment or non-residential premises, it is often necessary to move or expand door or other openings.

Cutting is also used when dismantling old buildings and structures: bridge supports, columns, balconies, foundations, piers, etc.

Features of cutting concrete with diamond wire

• It is necessary to mark the future cut.
• Drill it in the corners
• Then install the guide rollers
• Thread the rope into the resulting holes and then crimp it - “loop” it, first twisting it around its axis in the direction of tightening it. cable (so that the pearl wears out evenly over its entire diameter).
• After alm. The rope is tensioned and the required environment is established. Speed.

Important! When installing the cable, it is necessary to take into account the direction of rotation of the cable so that the rope does not rotate in the direction opposite to its opening. Usually there is an arrow on the rope plasticizer indicating in which direction the cable should rotate, but if there is no arrow, pay attention to diamonds (comets) and “comet tails” - the “comet” should not “fly” with its “tail” forward.

How to cut structures

In order to cut any structure, it is necessary to fasten the rope to it exactly on the line of the future cut. The mechanism, in turn, creates a strong tension on the cable, until it begins to cut the wall. In cases where it is necessary to create a recess in a reinforced concrete wall, it is necessary to drill special holes in it, where the cutting rope must then be inserted. The ends of the cable are then connected, creating a closed chain. After this, it is necessary to install a roller system that will ensure the movement of the cable. Further, the principle of operation of the mechanism remains the same as before. The cable is tensioned and cuts out the desired piece of surface. Thanks to this technology, a recess of the required dimensions can be easily created in a reinforced concrete wall, even a very strong one. In addition, when using this method of cutting concrete, further preparation of the structure is greatly simplified, since the cut edges are very even and smooth.

Of course, using this technique will be very expensive. But it is thanks to her that all the work will be done in the shortest possible time and very accurately.

Diamond wire consumption

Rope consumption depends on many factors:

1. Car condition. There is no point in saving on linings and other rubber bands; if they are already worn out, then during operation the rope undergoes additional testing. Load, which is why it may not produce its resource.
2. Compliance with sawing technology. As was said earlier, if the rotation speed is too low, the rope wears out faster, and if it is too high, it quickly becomes washed out. Therefore, if you have forgotten what speed you need to set, you shouldn’t experiment, it’s better to call, we will always tell you at what speed and other parameters you need to cut in those. or other conditions, this or that material.
3. Material. The service life of the rope also depends on the material that we need to cut - for granite, usually the higher its hardness group, the shorter the service life of the rope.
4. Twist. As was said earlier, the service life of the rope depends on its proper wear - it is necessary that the rope bead wears evenly over the entire diameter, in this case we can refine it to the end and achieve maximum service life.

Scope of use of rope cutting

Rope cutting

- This is a rather complex process from a technological point of view. Therefore, its use is justified only in cases where increased power is really required from the equipment, for example:

• when dismantling supports, columns and pillars with a diameter of 2 meters;
• when demolishing walls with a thickness of 1 meter and a cutting depth of 2 meters;
• when dismantling thickened foundations;
• when working with heavily reinforced materials (reinforcement diameter - from 1 centimeter);
• in the absence of access to the structure being cut from both sides.

In short, rope cutting is most effective when dismantling capital and reinforced structures, which otherwise can only be demolished using controlled explosions.
