Waterproof underground pipe gallery
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.
一种防水地下管廊，属于市政地下管道技术领域，所述管廊包括相互拼接的管片单体，所述管片单体的右侧连接端设有向右凸出的承口，另一管片单体的插口插入上一管片单体的承口的插接口处形成截面为L型的变形缝，变形缝内填充有聚乙烯泡沫板，变形缝拐角处设有矩形通道，聚乙烯泡沫板远离矩形通道的一端设有遇水膨胀橡胶胶条，拼接后两相邻管片单体的弧形外倒角边形成半圆形的凹槽，所述凹槽内填充有双组份聚硫密封胶，拼接后于变形缝对应位置的管片单体外壁湿铺防水卷材。本发明通过采用凸出的承口与插口插接形成截面为L型的变形缝，结合聚乙烯泡沫板、遇水膨胀橡胶胶条、双组份聚硫密封胶以及防水卷材，实现了管廊装配的防水目的。
