Description
Technical Field
The invention belongs to the technical field of rail transit or tunnels, and particularly relates to a method for arranging a flexible joint in an attached transverse channel pipe jacking method pipe joint.
Background
The main structure and the auxiliary structure of a station (tunnel) generally have the problems of large difference of structural mass and inconsistent structural style, and when the auxiliary structure and the main structure are rigidly connected, the main structure is usually dislocated and deformed due to differential settlement, so that more problems such as cracking, leakage and the like are caused. The open cut structure generally adopts a mode of setting deformation joints to solve the problems, but the structures such as a shield method, a pipe jacking method and the like are difficult to set the deformation joints. The pipe sections of the jacking pipes are tightly connected with the main body of the station (tunnel), the possible asynchronous settlement and deformation between the main body structure of the station (tunnel) and the pipe sections of the jacking pipes are balanced only through the joints between the pipe sections, and the allowable deformation is small. The pipe joints of the jacking pipes are different from the main structure of a station (tunnel) in structural scale and structural form, different settlement and deformation can be caused in the using process, and a joint with a special structure is urgently needed by a person skilled in the art, so that relative displacement within 5cm can be caused between adjacent structures, and respective relatively independent stress systems can be formed without damaging the safety of the structure.
