Problems solved by technology

[0002] With the increase of the service life of the shield subway tunnel, affected by the change of its own operating load and the surrounding environmental load, the shield subway tunnel segment often suffers from various diseases, including cracking, misalignment, differential settlement, water leakage, etc. In addition, the lining ring of the shield subway tunnel will undergo large deformation, which will affect the safety of the subway tunnel operation
[0003] At present, the rounding device integrated with the shield machine is mainly used to round the shield tunnel segment, but the shield machine is large in size and difficult to operate
Moreover, there are many pipelines in the subway tunnels in operation, and the headroom is limited, so it is often impossible to use traditional rounders for repair and reinforcement of subway tunnels in operation

Abstract

The invention relates to a shield tunnel repairing reinforcing platform and a reinforcing method. The platform comprises multiple sub-platforms which are arranged according to the set distance in thelongitudinal direction of a shield tunnel and vertically and flexibly connected and a platform base for transportation; each sub-platform comprises an operating platform arranged at the bottom and twoannular frames which are integrated with the operating platform, are arranged side by side and have the same structure; each annular frame comprises a hollow frame spindle, a telescopic bracket whichis connected with the platform base and the corresponding operating platform and used for achieving the supporting effect and supporting structures arranged in the circumferential direction of the annular frame; and each operating platform is provided with a control host and a hydraulic master machine. Compared with the prior art, the shield tunnel repairing reinforcing platform has the advantages that the functionality is high, efficient repairing can be achieved, and function extension is convenient.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a shield tunnel repair and reinforcement platform and a reinforcement method. Background technique [0002] With the increase of the service life of the shield subway tunnel, affected by the change of its own operating load and the surrounding environmental load, the shield subway tunnel segment often suffers from various diseases, including cracking, misalignment, differential settlement, water leakage, etc. In addition, the lining ring of the shield subway tunnel will be greatly deformed, which will affect the safety of the subway tunnel operation. [0003] At present, the rounding device integrated with the shield machine is mainly used to round the shield tunnel segment, but the shield machine is large in size and difficult to operate. Moreover, there are many pipelines in the subway tunnels in operation, and the headroom is limited, so it is often impossible to u...
