Problems solved by technology

[0003] The traditional waterproof measures for underground pipe corridors can only be waterproofed, but cannot be drained, resulting in poor waterproofing effect
Specifically, the surface of the main body of the pipe gallery is coated with a waterproof coating, a waterproof agent, or a waterproof membrane is laid. In this way, the service life of the waterproof coating, waterproof agent, or waterproof membrane is low; Self-waterproofing material, but this material is prone to cracks or water seepage at seams

Embodiment Construction

[0019] Such as figure 1 As shown, the waterproof structure of an underground pipe gallery in the present invention includes a pipe gallery main body, a waterproof layer, a cushion, a lining layer and a drainage pipe gallery. The waterproof layer is arranged on the outside of the pipe gallery main body and the cushion, and the cushion is arranged on the pipe gallery On the top of the main body, the cushion layer is a slope that slopes downward from the top to both sides. The lining layer is set on the outside of the waterproof layer, and the drainage pipe gallery is set on both sides of the bottom of the lining layer. Drainage channels distributed in a criss-cross pattern are connected to the drainage pipe gallery, and the lining layer is made of permeable materials.

[0020] The waterproof layer plays the role of waterproofing the main body of the pipe gallery. The groundwater blocked by the waterproof layer is discharged to the drainage pipe gallery through the drainage chann...

Abstract

The invention relates to an underground pipe gallery waterproof structure. The underground pipe gallery waterproof structure comprises a pipe gallery main body, waterproof layers, a cushion layer, lining layers and drainage pipe galleries, wherein the waterproof layers are correspondingly arranged on the outer side of the pipe gallery main body and the outer side of the cushion layer, the cushionlayer is arranged at the top of the pipe gallery main body, the cushion layer is an inclined plane which is inclined downwards from the top to the two sides, the lining layers are correspondingly arranged on the outer sides of the waterproof layers, the drainage pipe galleries are arranged on the two sides of the bottoms of the lining layers, a plurality of drainage channels which are distributedin a crisscross mode are arranged between the waterproof layers and the lining layers, the drainage channels are connected with the drainage pipe galleries, and the lining layers are formed by pilingwater permeable materials. The underground pipe gallery waterproof structure is simple in structure, good in waterproof effect and long in waterproof service life.

Description

technical field [0001] The invention relates to the technical field of underground pipe gallery waterproofing, in particular to an underground pipe gallery waterproof structure. Background technique [0002] With the development of cities, the application scale of underground utility corridors is getting larger and larger. The design of the underground pipe gallery has a long service life and has high requirements for waterproofing. Therefore, the long-term effectiveness of the waterproofing of the underground pipe gallery is an important factor that designers must consider. [0003] The traditional waterproof measures for underground pipe corridors are only waterproof, but not drainage, resulting in poor waterproof effect. Specifically, the surface of the main body of the pipe gallery is coated with a waterproof coating, a waterproof agent, or a waterproof membrane is laid. In this way, the service life of the waterproof coating, waterproof agent, or waterproof membrane is...
