Problems solved by technology

Whenever there is heavy rain, it mainly relies on "grey" facilities such as pipes, canals, and pump stations to drain water. The main planning and design concepts are "quick drainage" and "end-centralized" control. Rainwater is mainly drained through drainage facilities and cannot penetrate into the ground. It will cause waterlogging every time it rains, and the drought and flood will turn sharply, which does not meet the requirements of sponge city construction

Abstract

The invention discloses an urban road rainwater intercepting and purifying system and a construction method. The system comprises a rainwater floodway, a regulating reservoir and a flood storage tank, wherein at least two sewage interception devices are transversely arranged in the rainwater floodway, the rainwater floodway is provided with a water inlet pipe, the water inlet pipe is connected with rotational flow filters, and the rotational flow filters are provided with municipal pipelines and clear water outlet pipes. The construction method comprises the steps that (a) the rainwater floodway is constructed; (b) the sewage interception devices are installed in the main path of the rainwater floodway; (c) the sewage interception devices are flushed; (d) the regulating reservoir and the flood storage tank are cast; (e) the rotational flow filters are installed in branches of the rainwater floodway. Urban road rainwater is collected into two ways and are collected, filtered, purified, stored and utilized, the rainwater resource utilization efficiency is greatly improved, waste is turned into wealth, the problem of water resource shortage is relieved, the construction steps are simple, the difficulty is low, the construction quality is easy to control, the construction cost is low, and related construction devices are few.

Description

technical field [0001] The invention belongs to the technical field of water resource utilization in sponge cities, and in particular relates to an urban road rainwater interception and purification system and a construction method. Background technique [0002] With the advancement of urbanization, the increase of ground hardening has changed the original hydrological characteristics, resulting in increased rainwater runoff, frequent water accumulation on the road surface, and frequent large-scale water accumulation in some cities. The drop in groundwater level has intensified. In addition, the problem of water shortage in my country's cities is becoming more and more serious. The resource-based water shortage in the northern region and the water quality-based water shortage in the southern region. In this environment, the government proposed the goal of building a "sponge city" and supported it in various aspects such as policy and finance. [0003] Sponge city, as the n...
