Description

technical field [0001] The invention relates to the field of tunnels and underground engineering, in particular to the field of TBM tunnel construction under complex geological conditions. More specifically, it is a TBM excavation equipment that integrates hydraulic-mechanical rock breaking and wastewater treatment. More specifically, it is a hydraulic-mechanical combined rock breaking and wastewater treatment integrated TBM system. The present invention also relates to the construction method of the integrated TBM system of hydraulic machinery combined with rock breaking and wastewater treatment. Background technique [0002] With the increasing development of society, the demand for the use of TBM in tunnel and underground engineering is getting higher and higher. At present, there are mainly two types of TBM devices for rock breaking, one is to use ordinary roller hobs to break rock, and the other is to use hydraulic-mechanical combined rock breaking. The hydraulic-mech...

Problems solved by technology

Therefore, a large amount of high-pressure water is required in the process of work. After passing through the nozzle on the cutter head, it flows to the rock-breaking free surface (hand face), and then flows into the excavation tunnel, which increases the drainage pressure of the tunnel, especially in some water-containing tunnels. Geological environments with high water volumes make drainage more difficult during tunneling

[0003] To carry out high-pressure hydraulic cutting to break rocks will inevitably increase the amount of wastewater in the tunnel. If only relying on traditional drainage pumps to extract drainage, it will not only increase fuel consumption, but also increase the temperature inside the tunnel due to the mechanical heat generated by the drainage pump. high construction risk

With the excavation of the tunnel, the pipes to be laid will become longer and longer, which will undoubtedly increase the difficulty of drainage

Moreover, after the waste water in the excavation tunnel is extracted and discharged from the tunnel, if it is discharged directly without treatment, it will cause environmental pollution, and if it is all treated, it will greatly increase the construction cost
