Abstract

The invention provides an underground comprehensive pipe gallery structure with water prevention and water drainage functions and a construction method of the underground comprehensive pipe gallery structure, and relates to the technical field of comprehensive pipe gallery construction. The underground pipe gallery structure comprises a top waterproof concrete layer, a back filling layer, a pervious concrete layer, a waterproof layer, a comprehensive pipe galley body, U-shaped water drainage ditches, a bottom waterproof concrete layer, water-collecting wells, water drainage pipes and a U-shaped gable slope water drainage ditch. The gallery body can effectively dredge underground water and earth surface precipitation water, it is guaranteed that water circulation in original soil mass is not damaged, and the service life of the gallery body is indirectly prolonged. Meanwhile, the gallery body structure has an underground water and earth surface precipitation water collection function, improves the utilization rate of the underground water and the earth surface precipitation water, and accords with the conception of a sponge city. Pervious concrete is adopted as backfill, the backfill distance is long, the pervious concrete can play a role of flowing water choked flow, and flowing water corrosion of the galley body is reduced; and at the same time, the underground pipe gallery structure can eliminate road surface accumulated water, can prevent accumulated water congelation and road surface freezing swelling, and can be used as a secondary barrier to protect the comprehensivepipe gallery.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery construction, in particular to an underground comprehensive pipe gallery structure with waterproof and drainage functions and a construction method thereof. Background technique [0002] The comprehensive pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. With the rapid development of the country, it has become an irreversible trend to make full use of the underground space and save the above-ground space by building an underground comprehens...
