Problems solved by technology
However, in the process of actual use, it is found that TBM has many deficiencies in the working conditions of hard rock and extremely hard rock: (1) low penetration and tunneling speed, (2) large number of tool wear, (3) number of tool changes and Severe increase in cutting time, (4) a sharp drop in the utilization rate of tunneling operations, (5) increased life risks of main bearings and main drives, (6) increased risks of cutter head wear life, cracking, and deformation. construction efficiency, greatly increasing the cost of excavation
[0004] The high-pressure water jet rock breaking technology provides an idea to solve the problem of low tunneling efficiency of the current tunnel boring machine under hard rock conditions. When the TBM road boring machine encounters hard rock and extremely hard rock conditions It can greatly improve the excavation efficiency and reduce the excavation cost; however, when the high-pressure water jet assists rock breaking, the water pressure is as high as tens or even hundreds of MPa, and the water supply pipeline is easily broken due to the pressure, and the water supply pipeline flows out from the pump group to the TBM The cutter head requires a long run of tubing and if a leak occurs it is difficult to diagnose the location of the leak
In addition, if the water jet leakage is not detected in time, the pressure of tens or even hundreds of MPa flowing out of the pipeline may endanger the lives of construction personnel; in addition, due to the complex and changeable TBM construction conditions, if there is no scientific decision May cause a huge waste of resources

The invention provides a water jet assisted rock breaking intelligent control system and method. The method comprises the following steps: judging whether the water jet assisted rock breaking system is started or not according to the state of surrounding rock by acquiring the state of the surrounding rock; if the water jet assisted rock breaking system is started, detecting the water supply pressure and flow of the water jet assisted rock breaking system in real time, and transmitting the detection value to a diagnosis module; and when water supply pressure drop is greater than a set thresholdvalue, determining that a fault occurs, and closing the water jet assisted rock breaking system. The operation efficiency and the safety reliability of the water jet assisted rock breaking system areeffectively improved.
Description
technical field [0001] The present disclosure relates to a water jet assisted rock breaking intelligent control system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the strengthening of national infrastructure construction, the number of large underground caverns and tunnels is increasing year by year. Full-face tunnel boring machine (TBM) has become an indispensable large-scale construction machine, which has been widely used in construction due to its strong rock-breaking ability, excellent continuous construction, and simple operation. However, in the process of actual use, it is found that TBM has many deficiencies in the working conditions of hard rock and extremely hard rock: (1) low penetration and tunneling speed, (2) large number of tool wear, (3) number of tool changes and Severe increase in cutting time, (4...
