The invention provides a blocking and dredging device suitable for water burst and mud burst of a tunnel. The blocking and dredging device is used for solving the problem of water burst and mud burst in the prior art. Comprising a lead screw and a nut assembly, the lead screw is of 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, the nut assembly comprises a nut body and an outer gear, and the outer gear and the nut body are coaxially fixed; the rotation driving mechanism is used for driving the outer gear to rotate the spline shaft and the rotation stopping seat; the plug is fixed at the tail end of the lead screw, and a drainage hole is formed in the plug; the semiconductor refrigeration assembly is arranged on the lead screw in a sleeving mode, a refrigeration end is arranged on the outer side of the semiconductor refrigeration assembly, when the condition of water burst and mud burst occurs, water sequentially flows through the plug, the lead screw and the spline shaft to be discharged, and heat of the heating end is taken away in the water discharging process. The water flow dredging and seepage stopping functions can be achieved.
Description
technical field [0001] The invention relates to tunnel construction technology, in particular to a plugging and dredging device suitable for water gushing and mud gushing in tunnels. Background technique [0002] During the construction of the tunnel, due to the geological reasons of the tunnel, sometimes there will be water and mud gushing during the excavation process. [0003] In the event of water and mud gushing, the tunnel construction will be suspended, the tunnel face will be closed, and the construction will be suspended. Reinforce the surrounding rock at the position where the water gushes, strengthen the primary support, and guide the water to the water accumulation pit and pump it out of the hole with a centralized water pump. [0004] The existing problem is that the construction can only be carried out after the water has been drained, so how to effectively block the water and mud gushing position of the tunnel face and carry out subsequent construction has be...
