In the shield tunnel construction, a slag discharging and conveying system is an important factor for restricting the shield construction progress, and particularly in a hard rock tunneling stratum with large stratum fracture water in a long distance, the full-bin tunneling condition of the shield is easy to occur, so that the spiral conveyor discharges rare muck, the water content is too high, and the water-slag separation is serious. In the prior art, the front section of the belt conveyor at the rear part of the screw conveyor is provided with an angle, so that the water carrying capacity is poor, the friction force of a mixture of slag soil and water on the belt is too small, the slag water is easy to flow back to an assembly area, the shield is seriously influenced in slag discharge speed and tunneling efficiency, and the discharged slag water needs to be treated. At present, the manual cleaning mode is mainly adopted, but the visibility of the tunnel environment is low, the interference factors are many, the space is very limited, the manual auxiliary workload is large, the labor intensity of workers is high, and great waste is caused to manpower resources.

In view of the above problems, those skilled in the art have also been diligent in research and development to achieve some results, but still have the following drawbacks: for example, the patent application CN202110295006.6 discloses a device and a method for rapidly clearing and transporting muck of a shield belt conveyor in a water-rich stratum, which can rapidly clear and transport muck muddy water which falls from the bottom end of the belt conveyor and splashes to the lower part of the belt conveyor from two sides of the belt conveyor without affecting the normal propulsion of the shield machine on the basis of not occupying the construction space of a segment crane for lifting segments; however, although the problem of slag water treatment can be solved, the whole device is complex in design, difficult in operation process, large in occupied space, too high in equipment cost and difficult to maintain. For example, the utility model CN202020104831.4 discloses a belt conveyor with a water collecting device, which can collect muddy water flowing back on the belt conveyor by arranging a water collecting component below the belt conveyor, and discharge the collected muddy water into a sewage tank with the existing design through a pump, so as to avoid the pollution of duct pieces and tunnels and the damage of duct piece sealing; but it causes the pipeline to block up easily when clearing up the dregs, and the dregs are piled up to catchment subassembly lower part and are difficult for passing through the pipeline and discharge to influence the shield and construct the machine and normally tunnel.

In summary, in the tunneling process of the tunnel boring machine, various problems are faced when slag removal is needed, manpower and time are consumed for manual cleaning which is generally applied at first, while slag removal devices in the existing design respectively have some great defects, and how to enable the slag removal devices to efficiently remove slag and not to easily flow back on the basis of the existing structure and have small influence on the tunneling process is still a key and difficult problem to solve by technical personnel in the field.
