Description

Technical Field

[0001] The utility model relates to the technical field of waterproof reinforcement structures, in particular to a waterproof reinforcement structure for jacking pipe sections. Background Art

[0002] Pipe jacking construction refers to a concealed excavation construction method used when tunnels or underground pipelines cross various obstacles such as railways, roads, rivers or buildings. During construction, the pipe is pressed into the soil layer by a hydraulic jack supported on the rear seat of the foundation pit through force-transmitting jacking irons and guide rails, and the soil on the front of the pipe is excavated and transported away. When the first section of the pipe is completely pushed into the soil layer, the second section of the pipe is connected to the back and continues to be pushed in. In this way, the pipes are pushed in section by section, the interfaces are made, and culverts are built. The pipe jacking method is mainly used for the construction of underground water pipes, drainage pipes, gas pipes, and telecommunication cable pipes. It does not require excavation of the surface layer, and can cross highways, railways, rivers, ground buildings, underground structures, and various underground pipelines. It is a non-excavation construction method for laying underground pipelines.
