Complete equipment for repairing and reinforcing shield subway tunnel segments

Abstract

The invention discloses complete equipment for repairing and reinforcing shield subway tunnel segments, belongs to the technical field of tunnel construction equipment, and solves the problems that a trolley and a simple cantilever beam need to be modified for assistance during construction of existing segment repairing and reinforcing equipment, steel plate rings cannot be stored and transferred, the automation degree is low, the construction period is long, the construction cost is high, the construction difficulty is large, and the like. The complete equipment for repairing and reinforcing shield subway tunnel segments comprises a bottom system, an assembling robot system, a welding robot system and an auxiliary operation platform system. The complete equipment for repairing and reinforcing shield subway tunnel segments is high in automation degree, and adopts the mechanical operation for assisting in manual operation; and the equipment has the functions of storing, transferring and lifting the steel plate rings, automatically completes positioning installation and welding seam welding of the steel plate rings, effectively reduces the labor intensity of operators, and improves the operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a complete set of equipment for repairing and reinforcing a shield subway tunnel segment. Background technique [0002] At present, subway lines have been built and operated in major cities in China, and most of the subway interval tunnels are single-circle shield tunnels. According to relevant investigation data, during the operation period, due to the subway structure or the surrounding environment, the tunnel structure usually has deformation and other diseases, which generally include tunnel vertical displacement deformation, lateral displacement deformation, elliptic deformation (convergence deformation), cracks, seepage, etc. Leakage, etc., will affect operational safety in severe cases. In our country, the tunnels with an operation period of about 10 years need to enter the stage of renovation and restoration. [0003] The steel plate ri...

AI Technical Summary

Problems solved by technology

[0006] The shield tunnel steel lining reinforcement manipulator only discloses one kind of manipulator. Although the steel plate installation can be automated through the manipulator, it is still necessary to modify the trolley and simple cantilever for the actual repair and reinforcement of the tunnel segment. There is no such function as storage and transfer of steel plate rings, and automatic welding of steel plate rings cannot be realized, and processes such as steel plate ring installation, positioning and anchoring, overall welding, steel plate glue injection, and anti-corrosion treatment cannot be completed at one time. There is still a construction period Long, high construction cost, low construction efficiency, difficult construction, etc.
