Tunnel construction auxiliary technical equipment

Abstract

The invention relates to tunnel construction auxiliary technical equipment. The tunnel construction auxiliary technical equipment comprises a supporting base plate, a discharging device, a screw thread pushing device, a screw thread mounting device and a positioning device. The discharging device is connected with the upper end face of the middle part of the supporting base plate. The screw threadpushing device is located below the discharging device and is further installed at the top of the supporting base plate. The screw thread mounting device and the positioning device are both connectedwith the top of the left end of the supporting base plate, and the screw thread mounting device is located at the right end of the positioning device. The screw thread mounting device comprises a screw thread sleeve, screw thread clamping jaws, screw thread clamping jaw push rods, screw thread clamping plates, screw thread clamping plate push rods, a sleeve fixing rack, a screw thread rotating mechanism and a pipeline fixing mechanism. By adoption of the tunnel construction auxiliary technical equipment, the problems that when the sleeve is tripped in existing pipe-shed method construction for manual positioning of the sleeve and screw threads and manual connection of the screw threads and the sleeve, connection errors of the sleeve and the screw threads are large and connecting difficulties of the sleeve and the screw threads are high can be solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an auxiliary technical equipment for tunnel construction. Background technique [0002] The tube shed method construction or the umbrella arch method is an advanced support structure for shallow buried underground excavation of underground structural engineering. A steel pipe with a large moment of inertia is installed in the hole, which acts as a temporary advance support to prevent the soil layer from collapsing and surface subsidence, so as to ensure the safe operation of excavation and subsequent processes; As a new technology for tunneling in surrounding rocks, the pipe shed method was first used as an auxiliary method for tunnel construction. It played an important role in the construction of soft rock tunnels through broken zones, loose zones, and weak strata, and water and sand gushes. Since the pre-buried advanced pipe shed as roof and side wall support has ...
