The diamond wire cutting technology first appeared in quarries for sawing stone blocks, and then spread to the large-thickness concrete.
Today, a diamond wire is used for underwater cutting and dismantling large sections of heavily reinforced concrete at berths, dams, bridges, and also when working in confined spaces.
The underwater cutting process is quite laborious. Actually, everything happens under water, the master is constrained in his movements due to the special uniforms. Plus, it’s hard to warm up the metal, as the water is usually quite cold. The specialists of our company is carried out with using the wire saws, which are a steel ropes (cables) with cutting diamond components, reinforced in them. Thanks to the use of this effective technology, we quickly and with pinpoint precision cut the concrete at any depth of immersion of the berth and do bridge reconstruction, in a wide range of water and ambient temperatures, in a word, in a variety of conditions.
The cable is closed in an endless loop, means, the unit will work until it is disconnected from the power supply. And this means, that the work will go completely until the dismantling of the bridge or pier. Everything is extremely safe, since the construction is obviously attached to the crane, and at the end it immediately rises from under the water. The collapse or any excessive dangerous movement is impossible.
Sometimes the path of the cutter have to be laid. For this, a special hydraulic machine is used. Workers calculate the locations of the holes, lower the machine and it drills precisely and accurately. Then a wire saw is launched into these holes, and it begins to cut. Not only a smooth path is possible, but any, from oblique lines to even a zigzag.
The diamond wire cutting during the reconstruction of the bridge provides faster and more accurate work with reduced vibration and noise, compared to other methods of dismantling steel and reinforced concrete structures. This allows the operator to be at a safe distance from the cutting surface, reduce risks in terms of safety, while maintaining the structural integrity of the structures themselves - all this is very important while the work with damaged structures under water.
