Tunnel construction protection device based on municipal construction

Abstract

In order to solve the problem that protection is not easy to perform during tunnel construction in the prior art, the invention discloses a tunnel construction protection device based on municipal construction. The tunnel construction protection device comprises a bottom plate, universal wheels are uniformly mounted on the bottom surface of the bottom plate, a convex plate is welded to the upper surface of the bottom plate, a connecting rod is welded to the left side of the upper surface of the protruding plate, a handle is fixedly installed at the upper end of the left side face of the connecting rod, the protruding plate is sleeved with a clamping plate, a supporting rod is welded to the upper surface of the clamping plate, a lantern ring is welded to the top end of the left side face ofthe supporting rod, a guide frame is sleeved with the lantern ring, a fastening screw is installed between the lantern ring and the guide frame, a spiral spring is fixedly connected between the lowerend of the lantern ring and the guide frame, and a mounting block is welded to the top end of the guide frame. According to the device, a first motor and a second motor are reasonably used for controlling a connecting film, the connecting film is tensioned on the inner wall of a tunnel, tensioning of the inner wall of the tunnel is further achieved, and therefore safety protection is conducted during tunnel construction.

Description

technical field [0001] The invention relates to the field of municipal construction, in particular to a protection device for tunnel construction based on municipal construction. Background technique [0002] Municipal administration is the action of the municipal subject on the municipal object and its process. In a broad sense, municipal administration refers to the various management activities and processes of the city's political party organizations and state power organs in order to realize the political, economic, cultural and social development of the city itself and the country. Municipal administration in a narrow sense refers to the management activities and processes carried out by the national administrative organs of the city on various administrative affairs and social public affairs within the municipal area. [0003] Tunnel construction technology is mainly to study technical solutions and technical measures required for various construction methods of tunne...

AI Technical Summary

Problems solved by technology

[0004] However, during tunnel construction, when the inner wall of the tunnel is just formed, wiring or construction on the tunnel wall is required, and the tunnel will often be vibrated during construction. If the tunnel is not built firmly, it will be damaged during construction. The soil layer in the tunnel will be destroyed, so that there will be subsidence, and it is not easy to carry out safety protection in the process of construction in the tunnel, which is relatively dangerous. Therefore, it is urgent to design a protection device for tunnel construction based on municipal construction to solve the existing problems. lack of technology
