Socket and spigot structure for prefabricated assembly pipe gallery and construction method

Abstract

The invention discloses a socket and spigot structure for a prefabricated assembly pipe gallery and a construction method. The socket and spigot structure comprises a socket and a spigot which are inbutt joint, wherein the socket and the spigot are spliced through a rabbet, a splicing seam is reserved between the socket and the spigot, waterproof slurry is poured into the splicing seam, and the two ends of the splicing seam are blocked; a PC steel bar transversely penetrating through the splicing seam is arranged above the rabbet, and a water stop belt tightly attached to the inclined face isarranged at the inclined face above the rabbet; and the middle section of the rabbet and the lower portion of the rabbet are filled with joint filling plates, and a water-swelling rubber ring is arranged in the joint filling plate at the middle section of the rabbet. According to the socket and spigot structure, butt joint dislocation can be avoided, and the butt joint precision and the butt joint efficiency are effectively improved; uneven settlement of a foundation can be effectively prevented, and the anti-seismic and waterproof effects are achieved; and sealing and waterproof measures canbe achieved for the spigot, combination of working face compression rubber ring sealing and series connection compression can be formed by means of the PC steel bar, and the anti-seepage sealing andstress requirements can be met.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a socket structure and a construction method for a prefabricated assembled pipe gallery. Background technique [0002] The comprehensive pipe corridor is a large-scale comprehensive underground structure, also known as the underground urban pipeline comprehensive corridor. The main function of the comprehensive pipe gallery is to use the tunnel space built underneath to integrate water, electricity, gas and other engineering pipelines to realize unified management and maintenance of various underground pipelines, so that the underground pipelines can transfer corresponding water, electricity, and gas. and other resources, and serve the surrounding plots to meet the needs of municipal pipelines, reduce the secondary excavation of roads during the repair and expansion of underground pipelines in the later stage, and avoid affecting traffic. [0003] The waterproof pr...

Problems solved by technology

[0004] At present, the segment joints of the prefabricated integrated pipe gallery generally use rubber gaskets as the main waterproof measure. The opening and dislocation of the joints will cause the friction between the gaskets or between the gasket and the groove of the gasket to be less than the water pressure. There will be water leakage at the joint, which will inevitably lead to the aging of the rubber gasket, cracks and damage to the concrete at the joint, and will eventually corrode the internal equipment of the pipe gallery
