Abstract

The invention provides a high-pressure water jet injection device carried on a TBM and having sealing and anti-loosening functions. A high-pressure water jet spraying device body is included and comprises a high-pressure hose, a water spray rod and a water spray rod flange. The high-pressure water jet spraying device carried on the TBM and having the sealing and anti-loosening functions is characterized in that the high-pressure water jet spraying device with the sealing and anti-loosening functions further comprises a sealing and anti-loosening structure of the high-pressure hose, a sealing and anti-loosening structure of a water spraying rod flange bolt and a sealing and anti-loosening structure of the water spraying rod screw pad and screw sleeve. The device can realize sealing and looseness prevention of the water jet spraying device through effective looseness prevention at a plurality of key parts, is simple to process and manufacture, convenient to assemble and disassemble, good in structural stability and capable of adapting to structural vibration in the TBM field tunneling process, ensures stable use of a water jet high-pressure sealing surface, improves the tunneling efficiency of the TBM on extremely hard rocks, and reduces tool abrasion and tool changing times, the cost is saved, the construction period is shortened, and meanwhile popularization of the high-pressure water jet assisted rock breaking TBM technology is accelerated.

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,...
