Abstract

The invention relates to a device for breaking an underground obstacle under deep excavation conditions. The special rigid breaking device is installed on a telescopic arm of a telescopic arm excavator and is used for destroying the underground obstacle and removing residues of the obstacle from the original position; a special bucket is replaced into an ordinary bucket to be used for taking out the residues of the obstacle residue; the special rigid breaking device is composed of at least one breaking punch, a breaking punch connecting seat and a breaking punch mounting seat, wherein the breaking punch is conical, an inner cone hole is formed in the breaking punch, the breaking punch is connected with an outer cone at the front part of the breaking punch connecting seat through the innercone hole in a matched mode, moreover, the breaking punch is fixedly connected with the breaking punch connecting seat through a pin shaft, and the rear part of the breaking punch connecting seat is fixedly connected to the breaking punch mounting seat. According to the device for breaking the underground obstacle under the deep excavation conditions, the special breaking device is adopted for breaking the underground obstacle, and then the ordinary bucket is used for excavation. Meanwhile, under the condition of underwater operation, due to the fact that sight is blocked by water, the devicecan also be used for detectin, touching and excavating, therefore, the time can be saved, and the effects of being convenient and rapid are achieved.

Description

technical field [0001] The invention relates to a device for removing obstacles, in particular to a device for removing underground obstacles for underground projects such as deep foundation pit operations and sinking of caissons. Background technique [0002] When the caisson sinks or the deep foundation pit is excavated, there are underground hard obstacles due to poor geological conditions, which leads to sinking or obstruction of excavation, which adversely affects the construction period. And if the traditional manual removal is used, the efficiency is low, and the construction period may be further affected. Therefore, a set of efficient and fast equipment is needed to remove underground obstacles. Contents of the invention [0003] The present invention aims to solve the problem of removing obstacles during underground excavation, and provides a device for removing underground obstacles under deep excavation conditions. [0004] In order to achieve the above objec...
