Waterproof comprehensive pipe gallery structure of ecological system of sponge city

Abstract

The invention belongs to the technical field of rainwater reutilization and waterproof comprehensive pipe gallery construction and particularly relates to a waterproof comprehensive pipe gallery structure of an ecological system of a sponge city. The structure is used as a drainage device in heavy rain and applied for irrigation after raining, so that the content of heavy metal ions in rainwater is reduced, the influence on underground water is reduced, urban waterlogging is alleviated, the functions of the sponge city are realized, and ground precipitation is filtered and drained. Water in the soil around the comprehensive pipe gallery is collected and circulated, damaged caused to a gallery body by water accumulation at the periphery of the gallery body and water seepage, water leakage and the like in the gallery body, the service life of the gallery body is indirectly prolonged, and self-circulation of underground water in the soil can be formed; the waterproof and anti-corrosion construction problems of existing underground pipe galleries are solved, the maintenance cost of the underground pipe galleries in the later use period is reduced, and the service life of the underground pipe galleries is prevented from being shortened by water leakage and corrosion. In this way, the service life is prolonged, the problems of water acquirement, water utilization and the like of thecomprehensive pipe gallery are effectively solved, and the structure has high practicability and applicability.

Description

technical field [0001] The invention belongs to the technical field of rainwater reuse and waterproof construction of a comprehensive pipe gallery, and in particular relates to a waterproof structure of a comprehensive pipe gallery of a sponge city ecological system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, filters, and purifies water, and "releases" the stored water and uses it when necessary. [0003] With the development of urbanization, the accumulation of pollutants makes the pavement rainwater hold a large amount of pollutants. Some road runoff studies have shown that the pollution load in the i...

Problems solved by technology

[0005] In order to solve the above-mentioned existing technical problems, the present invention provides a waterproof structure of a comprehensive pipe gallery in the sponge city ecological system, which collects and circulates the water contained in the soil where the comprehensive pipe gallery is located, which can avoid the water storage around the gallery body, the corridor body Internal water seepage, water leakage, etc. cause damage to the gallery body, solve the waterproof and anti-corrosion construction problems of the existing underground pipe gallery, reduce the maintenance cost of the underground pipe gallery after use, and avoid shortening the service life of the underground pipe gallery due to water leakage and corrosion
