Geological survey device for underground adverse engineering

Abstract

The invention discloses a geological survey device for underground adverse engineering, and relates to the technical field of geological survey and engineering construction. The problems that an existing geological survey device needs to manually replace a drill rod in use, the operation is troublesome in the replacement process, the workload of workers is large, meanwhile, the replacement speed is low, and the working efficiency is low are solved. The device comprises a survey machine body, wherein a set of rotating seats are rotationally connected to the right side of the survey machine body; a set of drill rod grabbing driving pieces are fixedly connected to the upper portion of the front end face of a grabbing seat; two sets of grabbing blocks are connected to the rear portion of the grabbing seat in an up-down sliding mode; and two sets of bottom drill rod fixing driving rods are rotationally connected to the inner side of the lower portion of the survey machine body. According tothe device, a series of actions such as automatic fixing of the drill rod on the lower portion, automatic loosening of the drill rod, automatic grabbing of the drill rod, automatic feeding of the drill rod and automatic tightening of the drill rod are achieved, automatic drill rod adding is achieved, the automation degree is high, the operation of workers is greatly reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to the technical fields of geological survey and engineering construction, in particular to a geological survey device for underground unfavorable engineering. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep below the ground to develop and utilize underground space resources. It includes underground houses and underground structures, underground railways, highway tunnels, underwater tunnels, underground common trenches, and underground passages for street crossings. Unfavorable geological conditions are often encountered in construction. Unfavorable geological conditions generally refer to various geological phenomena mainly caused by extraterrestrial dynamics, such as collapses, landslides, debris flows, karsts, soil caves, river erosion, and seepage deformation. Therefore, during construction It is often necessary to survey unfavorable geological conditions. In geo...
