Maintenance method of prefabricated concrete culvert, prefabricated integrated pipe gallery and integrated pipe gallery

Abstract

The invention provides a maintenance method for a prefabricated concrete culvert, a prefabricated comprehensive pipe gallery and a comprehensive pipe gallery. The annular end surfaces of both ends of the prefabricated concrete culvert contain waterproof and drainage structures, and the waterproof and drainage structure includes The drain groove (1) and the sealant strip installation groove (2) are arranged in the direction, the sealant strip installation groove (2) is located between the drain groove (1) and the outer surface of the prefabricated concrete culvert pipe, the drain groove (1) to the The distance from the outer surface of the prefabricated concrete culvert is smaller than the distance from the drainage groove (1) to the inner surface of the prefabricated concrete culvert. The maintenance method of the prefabricated concrete culvert, prefabricated comprehensive pipe gallery and comprehensive pipe gallery solves the waterproof problem of the splicing parts, and realizes the combination of "prevention, drainage and blocking". After the material life expires, the waterproof interface can be repaired to ensure the waterproof effect .

Description
