[0001] The invention relates to the technical field of tunnel excavation, and in particular to a construction method in which a split anchor drilling vehicle is matched with a tunneling machine. Background Art

[0002] At present, in the process of tunnel excavation construction in my country, the matching of monorail hydraulic anchor drilling vehicle and tunnel boring machine has gradually begun to be used on a small scale. This monorail hanging equipment is suspended on the suspension rail at the top of the tunnel, with its own power, and moves forward and backward on the track; while the tunnel boring machine matched with it walks on the bottom plate of the tunnel. This tunnel excavation construction process using a monorail hydraulic anchor drilling vehicle and a tunnel boring machine does not have "left and right car errors", saves auxiliary time, and has higher operating efficiency. However, since the entire main frame of the monorail hydraulic anchor drilling vehicle is suspended above the tunnel boring machine cab during support, when encountering a low and narrow tunnel, the height space between the monorail anchor drilling vehicle frame and the tunnel boring machine cab is very small, and the tunnel boring machine driver cannot sit in the cab to operate, and the monorail anchor drilling vehicle frame is suspended above the tunnel boring machine cab for construction, there are also safety hazards, which is also an important factor restricting the popularization of the matching use of monorail hydraulic anchor drilling vehicles and tunnel boring machines.
