Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] The present invention is a waterproof underground pipe gallery. The pipe gallery includes segment pieces spliced with each other. The left connecting end is a socket 2, and the socket 1 is set along the cross section of the right connecting end of the segment unit. The socket 1 is indented from the outer wall of the segment unit to form a socket, and the other segment The socket 2 of the single body is inserted into the socket port 1 of the previous segment body to form a deformation seam 10 with an L-shaped cross section. The deformation seam 10 is filled with polyethylene foam board 4, and the corner of the deformation seam 10 is provided with a rectangular shape. Channel 3, the rectangular channel 3 is an annular cavity. One end of the polyethylene foam board 4 away from the rectangular channel 3 is provided with a water-swellable rubber ...

Abstract
The invention provides a waterproof underground pipe gallery, and belongs to the technical field of municipal underground pipelines. The waterproof underground pipe gallery comprises pipe piece singlebodies which are spliced with each other. A bell mouth protruding rightwards is arranged at the connecting end of the right side of each pipe piece single body, and an inserting opening of the otherpipe piece single body is inserted into an inserting opening of the bell mouth of the previous pipe piece single body to form a deformation joint with an L-shaped section. The deformation joint is filled with a polyethylene foam plate, a rectangular channel is formed in the corner of the deformation joint, a water swelling rubber strip is arranged at the end, away from the rectangular channel, ofthe polyethylene foam plate, the arc-shaped outer chamfered edges of every two adjacent pipe piece single bodies form a semicircular groove after splicing, the grooves are filled with double-componentpolysulfide sealants, and after splicing, a waterproof coiled material is wetly paved on the outer walls of the pipe piece single bodies at a position corresponding to the deformation joint. The deformation joint with the L-shaped section is formed by inserting the protruding bell mouth and the inserting opening, and the polyethylene foam plate, the water swelling rubber strip, the two-componentpolysulfide sealant and the waterproof coiled material are combined, so that the waterproof purpose of pipe gallery assembly is achieved.
Description
technical field [0001] The invention belongs to the technical field of municipal underground pipelines, in particular to a waterproof underground pipeline gallery. Background technique [0002] The urban underground comprehensive pipe gallery is an intensive and modern urban pipe gallery system integrating power, communication, heating, water supply and drainage, gas and other engineering pipelines. It plays an important coordinating role in the construction of urban infrastructure. With the construction and development of urban infrastructure, the existing urban underground utility corridors are diverse, mainly reflected in structural design and construction. In order to prevent itself from cracks or damage, the splicing joint of the underground pipe gallery segment is a very important position, and when there are cracks and water seepage in the underground pipe gallery, it may be necessary to destroy a large piece of rigid protective layer, resulting in high maintenance co...
