Problems solved by technology

However, the production of high-pressure water jets requires a complete set of high-pressure water generation, transmission, injection devices, control systems, and several safety protection measures. At the same time, it is necessary to fully consider the compatibility of high-pressure water jet systems with existing TBM structures and constructions. There are still many technical problems to be solved
[0005] During TBM construction, when the hob cutter head interacts with the rock, strong vibrations will be generated, which will reduce the sealing performance of the high-pressure water jet injection device. The safety and stable operation of the water-assisted rock breaking system are affected

Description

technical field [0001] The invention relates to the technical field of high-pressure water coupled rock-breaking TBM, in particular to a high-pressure water jet injection device mounted on a TBM with a sealing and anti-loosening function. Background technique [0002] The full-face rock tunnel boring machine (abbreviated as TBM) is widely used in tunnel engineering due to its advantages of high efficiency, environmental protection and high degree of automation. The traditional TBM uses a disc-shaped hob as a cutting tool for breaking rocks. Under the action of the torque and thrust of the TBM drive system, the disc-shaped hob penetrates into the rock and rotates with the rotation of the cutter head to cut the rock. The bottom is crushed and forms radial cracks, and as the cracks expand, rock fragments are formed to achieve the purpose of breaking rocks. [0003] As TBM encounters more and more geology with large buried depth, high confining pressure and extremely hard rock,...
