Waterproof structure of outer wall of comprehensive pipe gallery

Abstract

The invention provides a waterproof structure of an outer wall of a comprehensive pipe gallery. The structure comprises three constituent parts, namely, a top plate waterproof structure, a side wall waterproof structure and a bottom plate waterproof structure; the top plate waterproof structure is sequentially provided with a self-waterproof concrete structure layer, a non-cured rubber asphalt waterproof coating layer, a double-sided self-adhesion root-puncture-resistant waterproof roll material layer, a dry-laid felt isolation layer and a fine stone concrete protective layer from inside to outside; the side wall waterproof structure sequentially comprises a self-waterproof concrete structure layer, a non-cured rubber asphalt waterproof coating layer, a double-sided self-adhesion waterproof roll material layer, a polystyrene foam plastic board layer and a coal ash solid brick protective layer from inside to outside; and the bottom plate waterproof structure is sequentially provided with a fine stone concrete protective layer, a double-sided self-adhesion waterproof roll material layer, a fine stone concrete slope making layer, a self-waterproof concrete structure layer and an indoor fine stone concrete slope making layer from outside to inside. According to the structure, an inner and outer waterproof combined mode is adopted, and a plurality of waterproof defense lines are organized, so that the problems of water seepage and water leakage caused by too many holes and branch pipes of the comprehensive pipe gallery are solved.

Description

technical field [0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery, in particular to a waterproof structure for the outer wall of the comprehensive pipe gallery. Background technique [0002] With the rapid development of urban comprehensive utility corridors in recent years, more and more comprehensive utility corridors that have been built have exposed different degrees of water leakage. Once the underground comprehensive pipe gallery leaks, it will directly affect the use and maintenance of the pipe gallery. If the water leakage is serious, the comprehensive pipe gallery will even be scrapped, endangering the urban pipeline project and paralyzing the city. The consequences are very serious. so. In the design stage of the pipe gallery, it is necessary to consider the waterproof problem carefully in advance, and to complete the design tasks in the construction stage with quality and quantity, so as to reduce or even avoid th...
