Description

Technical Field

[0002] With the continuous advancement of social and economic development and urbanization, in order to make the city beautiful and clean, various underground pipelines such as municipal, communication, water supply and drainage are concentrated in underground pipeline corridors.

[0003] As an underground municipal engineering project, underground pipe corridors generally adopt two construction methods: one is prefabrication and assembly in sections, and the other is open excavation and cast-in-place. Both methods require the use of pipe corridor deformation joints to connect the pipe corridors into a linear whole. Since the pipe corridor is an underground project, groundwater and deformation of the soil around the pipe corridor will exert force on the pipe corridor, affecting the waterproof state of the pipe corridor. Generally, the main body of the underground pipe corridor adopts a self-waterproof reinforced concrete structure, which has a certain waterproof function. The deformation joints of the pipe corridor are the key waterproof parts. The damage to the underground pipe corridor caused by the uneven settlement of the surrounding soil mostly occurs at the deformation joints of the pipe corridor, causing the deformation joints of the pipe corridor to deform in multiple directions, affecting the waterproof effect of the deformation joints of the pipe corridor.

[0004] Traditionally, the connection treatment of the deformation joint of the pipe gallery generally adopts the rigid connection of steel bars. When the pipe gallery undergoes multi-directional displacement deformation, it is easy to damage the filling material in the deformation joint of the pipe gallery and it is difficult to repair, thus causing water seepage. Therefore, the utility model proposes a waterproof structure for the deformation joint of the pipe gallery adapted to multi-directional displacement to solve the above problem. Utility Model Content
