The invention provides a plugging and dredging device suitable for water inrush and mud inrush in a tunnel, which is used to solve the problem of water inrush and mud inrush in the prior art. It includes: a lead screw and a nut assembly, the lead screw is a hollow structure, the nut assembly is matched with the lead screw, the displacement of the nut assembly in the axial direction of the lead screw is limited, and the nut assembly includes A nut body and an external gear, the external gear and the nut body are coaxially fixed; a rotary drive mechanism, which is used to drive the external gear to rotate the spline shaft and the anti-rotation seat; a plug, the plug The head is fixed on the end of the lead screw, and the plug is provided with a drainage hole; the semiconductor refrigeration assembly is sleeved on the lead screw, and the outer side of the semiconductor refrigeration assembly is the refrigeration end. When the mud is in the state, the water flows through the plug, the lead screw and the spline shaft in turn to be discharged, and the heat of the heating end is taken away during the water discharge process. The present application can realize the functions of dredging water flow and preventing seepage.
Description
technical field [0001] The invention relates to tunnel construction technology, in particular to a plugging and dredging device suitable for tunnel water inrush and mud inrush. Background technique [0002] In the process of tunnel construction, due to the geological reasons of the tunnel, sometimes there will be water inrush and mud inrush during the excavation process. [0003] In the event of water inrush and mud inrush, the tunnel construction will be suspended, the face of the tunnel will be closed, and construction will be suspended. Reinforce the surrounding rock at the water gushing position, strengthen the initial support, and concentrate the water into the stagnant pit and pump it out of the hole with a pump. [0004] The existing problem is: the water needs to be drained before the construction can be carried out, so how to effectively seal the position of the water gushing mud on the face of the face and carry out the subsequent construction has become a problem...
