[0002] With the continuous improvement of infrastructure construction technology, underground engineering construction presents a rapid development trend, and many deep-buried high-pressure water-rich tunnels appear, and sometimes sudden heavy gushing or flood caused by bursting mountain torrents occurs in poor geological sections, which leads to the destruction of the existing pumping and draining system and causes tunnel flooding.

[0003] After tunnel flooding, the existing construction inclined shaft is usually used for reverse slope pumping and draining construction, and the pumping and draining system needs to be moved forward constantly as the water level drops, so that the accumulated water in the tunnel can be quickly pumped and drained. When the existing pumping and draining system moves along the slope, the conventional method is to install a walking system at the bottom of the draining system to move by using self-weight or external force traction.

[0004] When the reverse slope emergency pumping and draining is carried out in the small cross section and large slope inclined shaft, the pumping and draining system moves underwater (ensures the submergence depth of the water pump), and there is a problem that the moving position is not accurate, and once the moving direction deviates, there is not enough space for horizontal deviation rectification and direction adjustment, at this time, the pumping and draining system needs to be withdrawn and re-advanced, which takes a long time, reduces the pumping and draining efficiency, and easily damages the pumping and draining system.
