Drilling system and construction method for avoiding tunnel water and mud

Abstract

The present invention provides a drilling system and a construction method for avoiding the intrusion of water and mud in a tunnel, which are used to solve the problems in the prior art that the intrusion of water and mud in the drilling process cannot be handled and the construction period is delayed. A drilling system for avoiding water and mud in a tunnel, comprising: a drill bit, a drill pipe, a driving mechanism, an axial compression mechanism and a semiconductor refrigeration assembly, the drill bit is installed at one end of the drill pipe, and the other side of the drill pipe is installed. One end is provided with a clamping disk, the drill bit and the drill rod are hollow structures and communicate with each other to form a drainage channel; the axial pressing mechanism includes a limit component, a second power component, a rack and a second drive gear, the limit The positioning assembly limits the axial ends of the chucking plate, the rack is fixed on the limiting assembly, and the second driving gear meshes with the rack; the semiconductor refrigeration assembly is rotated and sleeved On the drill pipe, the inner side of the semiconductor refrigeration assembly is the heat dissipation end, and the outer side of the semiconductor refrigeration assembly is the cooling end.

Description

technical field [0001] The invention belongs to the technical field of exploration and construction, and in particular relates to a drilling system and a construction method for avoiding tunnel water and mud intrusion. 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 inflow position, strengthen the initial support, and concentrate the water to the stagnant pit and pump it out of the hole with a pump. [0004] In the process of digging the inclined shaft of the tunnel, the closer to the earth's core, the higher the temperature, so it is necessary to solve the problem of water inrush and mud inrush caused by water seep...
