Description

[0001] The invention relates to the technical field of tunnel construction equipment, and in particular to tunnel anchoring construction equipment. Background Art

[0002] Cables, power lines, signal lines, etc. are laid inside the tunnel. These lines are generally positioned and laid through wire tubes. The wire tubes are fixed to the inside of the tunnel with screws or wire tube clamps. As a result, various fixed positions are formed on the inner wall of the tunnel. Often, holes are drilled at the fixed positions to install internal threaded rivets and then positioned and fixed with screws.

[0003] Since steel bars are arranged in the tunnel support structure, it is necessary to avoid the steel bars when drilling holes and anchoring internal threaded rivet columns, otherwise the drilling equipment will be damaged and even the performance of the tunnel support structure will be affected, or the fixing performance of the drilled holes will be poor.

[0004] In the prior art, when fixing screws on the inner wall of a tunnel, a method of first detecting, then drilling, and finally grouting anchors is adopted. However, the three steps require the entire equipment to be continuously moved in a small range. If there is a deviation in the displacement, the point position will be inaccurate and it is easy to hit the steel bars. In addition, if different points in the same layer have steel bars and some do not, the machine needs to constantly change its position, which is not only troublesome to operate but also increases the probability of deviation.
