Abstract

The invention discloses a novel tunnel construction supporting device. The novel tunnel construction supporting device structurally comprises a supporting plate, a telescopic bracket, a passage archeddoor, a bracket fixing plate, a fixed base, a connecting sleeve frame, movable hinges, a folding bracket, an adjusting rod, a screw rod, a positioning pin, a positioning hole and an adjusting nut. The novel tunnel construction supporting device has the beneficial effects that the middle opposite angles of the telescopic bracket are in threaded connection with the screw rod contained in the adjusting rod, and penetrating is achieved; movable hinges are arranged on the corners of the telescopic bracket so that angle adjusting of the corners can be conducted; transverse opposite angle distance control of the telescopic bracket is realized according to rotating of the screw rod, so that the vertical opposite angle distance of the telescopic bracket changes, in this way, telescopic control onthe supporting plate is achieved, adjusting of the supporting angle, the distance and the fit degree by construction staff can be effectively facilitated, supporting hanging points are avoided, and safety of tunnel construction is improved.

Description

technical field [0001] The invention relates to a support device for tunnel construction, which belongs to the field of support devices for tunnel construction. Background technique [0002] At present, in the construction of tunnels, due to its particularity, it is necessary to support the tunnels under construction to ensure the safety during the construction process and ensure that there is nothing wrong with it. Generally, in the process of tunnel construction, it is supported by side construction and piling, and then laying support pipes. There are certain difficulties, resulting in the difficulty of tunnel construction. [0003] The prior art cannot adjust the fitting degree and support angle of the support surface, which leads to the suspense points on the support surface and affects the safety of tunnel construction. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a support device...
