Filtering, purifying, collecting and drainage system for urban roads

Abstract

The invention relates to a filtering, purifying, collecting and drainage system for urban roads. A pavement structure comprises motor vehicle lanes, curbs, sidewalks, lawns, regulating reservoirs, municipal pipe networks and the like sequentially from middle to two sides; a gravel filtering layer, a purifying medium layer, an activated carbon core filtering layer and a geotextile layer are arranged below the motor vehicle lanes, the curbs and the sidewalks, a plurality of rainwater collection modules are provided, drainage collecting pipelines are connected to an urban pipeline, and a gravel-grit layer is arranged at the bottommost end of the whole pavement structure. When the pavement slopes, the whole pavement structure is preferentially perpendicular to the slope. The filtering, purifying, collecting and drainage system for urban roads has the advantages that the system has simple structure, good performance under stress, high bearing capacity and good quality and is capable of recycling, storing, filtering and purifying rainwater, clipping peaks for regulation, conserving lawns, and improving underground water sources and the environments such as ecology and soil, and the pavement ponding problem is effectively solved.

Description

technical field [0001] The invention belongs to the technical control field of water collection and drainage and rainwater filtration and purification treatment, and in particular relates to an urban road filtration and purification and collection and drainage 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] Due to the traditional urban construction model, the roads are hardened everywhere, and the city becomes very "hard", unable to breathe, and heavy rains are prone to urban waterlogging. As an importa...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides an urban road filtration and purification and collection and drainage system, which can effectively overcome the problems that the existing urban drainage pipe network system cannot solve the problems of water system pollution caused by rainwater runoff and waterlogging caused by rainstorm runoff; the structure is simple, Good mechanical performance, strong bearing capacity, stable quality, automatic control of rain collection, sewage interception, filtration, sterilization, water purification, peak shaving and storage, and lawn conservation; improvement of groundwater sources, ecology, soil and other environments, and appearance It is beautiful and has great significance for the realization of the goal of lawn conservation and water ecological restoration
