Problems solved by technology

[0004] The present invention aims at the problem that the existing pipeline leakage repair technology is insufficient, and provides a ground rainwater comprehensive utilization system and a rainwater purification method. The system can comprehensively utilize rainwater, and the roadside hidden underground water channel is used to quickly flow the road surface rainwater into it, so that the road surface is not clean. Water accumulation is generated, and at the same time, part of the inflowing rainwater is introduced into the landscape green space through spiral pipes, and collected in the underground reservoir through the filtration of the soil strata, and the water in the reservoir is also comprehensively utilized

Abstract

The invention discloses a ground rainwater comprehensive utilization system and a rainwater purification method. A water permeating layer is arranged below road ground. A combination layer is arranged below the water permeating layer. A reinforced concrete layer is arranged below the combination layer. Multiple water seepage pipelines penetrate the reinforced concrete layer and are connected to a water seepage flow collecting pipeline. The water seepage flow collecting pipeline communicates with a hidden underground water channel. The hidden underground water channel is provided with a hidden underground water channel transmission pipe opening. The hidden underground water channel transmission pipe opening is connected with a coil pipeline through a rainwater transmission pipeline. The tail end of the coil pipeline is connected with a bio-retention pond. One end of a river entering net pipeline is connected with a brake valve, and the other end of the river entering net pipeline communicates with a river channel. An opening of the bio-retention pond communicates with the bio-retention pond. A water purification system is arranged below the bio-retention pond. By the adoption of the system, rainwater can be comprehensively utilized, the roadside hidden underground water channel is adopted, part of flow-in rainwater is guided in a landscape greenbelt through the coil pipeline, and the rainwater is filtered through a soil stratum to be collected in an underground reservoir.

Description

technical field [0001] The invention belongs to the technical field of rainwater comprehensive utilization, and in particular relates to a ground rainwater comprehensive utilization system and a rainwater purification method. Background technique [0002] The shortage of water resources has become a prominent problem in the development of many cities. At present, more than 400 of the more than 600 cities in my country are short of water, of which more than 100 cities are seriously short of water, and the unreasonable discharge of production and domestic sewage in cities has caused water supply sources to be polluted, making urban water resources more scarce and seriously affecting sustainable economic and social development. As a hard system that accounts for nearly 1 / 3 of the urban built-up area, urban roads, like building roofs, are one of the most important rainwater receiving surfaces in the city, and are the main sites for the generation, collection and final discharge ...
