Description

Technical Field

[0001] The invention relates to the technical field of belt water washing, and in particular to a matching belt water washing device for a TBM rock burst tunnel. Background Art

[0002] TBM (Tunnel Boring Machine) is an efficient and safe underground tunnel excavation equipment, widely used in urban subway, water conservancy, transportation and energy fields. In the process of TBM excavation, rock burst is a common adverse phenomenon, which may lead to serious safety accidents and project delays. In order to reduce the risk of rock burst and improve the efficiency and quality of tunnel excavation, a belt washing device is equipped to clean the rock formation in front of the tunnel boring machine in time. In the process of TBM excavation, as the machine head moves forward, various impurities and dust may exist on the surface of the rock formation, which will affect the normal operation of the tunnel boring machine and may even cause trucks or claws to jam. The belt washing device can clean these impurities in time, keep the rock surface clean and smooth, and facilitate the smooth advancement of TBM. During TBM excavation, due to mechanical friction and rock crushing, the rock surface will generate high temperature. Long-term high temperature can easily cause the rock to soften, melt or even burst, increasing the risk of rock burst. By continuously spraying clean water, the temperature of the rock can be effectively reduced, the deformation and cracking of the rock can be reduced, and the safety of tunnel excavation can be improved. During rock excavation, mechanical vibration and rock crushing will generate a lot of dust, which not only affects the health of workers, but also easily causes mechanical equipment failure. By spraying clean water in time, the generation of dust can be suppressed, the working environment can be improved, the health of workers can be protected, and the cost of equipment maintenance and the risk of project delays can be reduced.
