With the continuous development of the city scale, some existing buildings in the old city reach or approach the design life, which can not meet the requirements of the new code (earthquake or fire protection), and can not meet the needs of people's production and life. Therefore, they are faced with two choices: structural transformation, reinforcement and demolition.
The old city has a large building density and narrow space, and the noise generated by mechanical crushing and demolition will affect the production and life of people around it. Therefore, it is very important to choose the construction technology without vibration, no pollution and no noise. Thirdly, we recommend the static cutting and hoisting technology of diamond rope saw
First, diamond cutting principle.
Diamond rope saw cutting is driven by a hydraulic machine to move around the cutting surface at high speed to complete the cutting work. Due to the use of diamond single crystal as grinding material, hard objects such as stone, reinforced concrete can be cut. The cutting is driven by a hydraulic motor, and the hydraulic pump runs smoothly, which can be controlled remotely through high-pressure tubing. Therefore, the cutting process is not only safe and convenient, but also free of vibration and noise. The cutting object can be separated with almost no interference. During the cutting process, the high-speed diamond rope is cooled by water, taking away the grinding debris, and there is no environmental pollution.
Two, diamond rope saw cutting construction characteristics.
1) Large reinforced concrete structures are not limited by the volume and shape of the cutting material.
2) Seven in any direction can be implemented, such as horizontal, vertical, diagonal, etc.
3) Fast cutting speed, high efficiency, can shorten the construction period, cutting speed of about 2-3m2/h.
4) Cutting construction process without vibration, noise, dust, environmental protection.
5) In some specific environments, such as underwater, dangerous operation areas and other general equipment, cutting technology is difficult to complete.
Three, diamond rope saw cutting scope.
1) Cut and dismantle reinforced concrete floors, frame beams, frame columns, shear walls and other main structures.
2) Cutting and dismantling of reinforced concrete T beams (box beams, etc.), cover beams, piers, retaining walls and other main structures in bridge engineering
