While-drilling follow-up pipe shed construction device and construction method

Abstract

The invention discloses a while-drilling follow-up pipe shed construction device which comprises a pipe shed pipe grabbing assembly, a buckling and pressing assembly and a root pipe drill bit. The pipe shed pipe grabbing assembly comprises a rotating shaft, a power piece and a first mechanical arm. The buckling and pressing assembly comprises a buckling and pressing machine; a rock drill of a drill jumbo drives a drill rod to penetrate through the buckling and pressing machine and is connected with the root pipe drill bit, a pipe shed pipe sleeves the drill rod, the root pipe drill bit and the pipe shed pipe are fastened together by the buckling and pressing machine, the drill rod can drive the pipe shed pipe to advance while drilling, synchronous mounting is realized, the problem that a pipe shed cannot be mounted when it is hard to form the hole is solved, and the mounting efficiency is improved; and the two pipe shed pipes can be buckled and pressed together through the buckling and pressing machine, so that threaded connection between the pipe shed pipes is replaced, the connecting time of the pipe shed pipes is shortened, and the mounting efficiency is improved. The invention further discloses a while-drilling follow-up pipe shed construction method, the follow-up-while-drilling pipe shed construction device is adopted, the pipe shed pipe can be automatically installed while drilling is achieved, and the mounting efficiency is high.

Description

technical field [0001] The invention relates to the field of installation of pipe sheds, in particular to a construction device and method for following up pipe sheds while drilling. Background technique [0002] Pipe shed construction is an advanced support measure used in tunnel engineering under adverse geological conditions such as weak surrounding rock, broken zones, and karst caves. It is used to prevent soil layer collapse and surface subsidence, and improve the safety of tunnel excavation. [0003] The problems existing in the construction of the existing pipe shed are: 1. Generally, the method of drilling first and then installing the pipe shed is adopted. When the hole collapses and the hole is difficult to form, there is a problem that the pipe shed cannot be installed, and the construction efficiency is low; 2. Some Follow-up pipe shed construction while drilling, process threaded fasteners on the pipe shed, and manually connect two pipe sheds, the labor intensit...
