Sponge city construction road rainwater treatment system

Abstract

The invention provides a sponge city construction road rainwater treatment system, which comprises a water seepage road surface, a soil-stone mixing layer, a concrete layer and a base soil layer. Theconcrete layer forms openings at downward concave parts; gravel layers are arranged on the opening parts; each opening is connected with a collecting pipe; a water distributor, a clear water chamber and a water storage chamber are arranged in the base oil layer; the collecting pipe is communicated with the water distributor; a filtering structure is arranged above the clear water chamber, and comprises a first filtering chamber and a second filtering chamber; a first channel and a second channel are arranged in the water distributor; the second filtering chamber comprises a water distributionplate and a circle levee which are arranged at an interval; a filter cloth is arranged between the circle levee and the water distribution plate; an overflow port is formed in a side wall of the circle levee; a filtering layer is arranged on the bottom part of the first filtering chamber; the clear water chamber is located under the filtering layer; a drainage hole is formed in the first filteringchamber and is communicated with the water storage chamber through a drainage pipe; a control mechanism for controlling the first channel or the second channel to open and close is arranged on the water distributor. According to the scheme, rainwater can be collected, purified and stored for users to use.

Description

technical field [0001] The invention relates to the field of urban construction, in particular to a road rainwater treatment system for sponge city construction. Background technique [0002] Buildings in our country are basically made of hard pavement and have no rainwater storage and drainage capacity. Once a heavy rainstorm occurs, a large amount of rainwater will flow into the municipal pipe network for drainage. Not only the rainwater can only flow into the river in vain, but once the drainage is not smooth, there will be Urban waterlogging phenomenon, and this kind of hard pavement increases the "heat island benefit" of the city. The construction of the sponge city is to solve the above problems, and implement functions such as absorption, infiltration, stagnation, storage, purification, utilization, and drainage of rainwater for various urban facilities to promote the local consumption and utilization of urban rainwater. But as far as the current road is concerned, e...

Problems solved by technology

But as far as the current road is concerned, even if the green space is designed to be concave, it is still difficult to drain the rainwater when it encounters heavy rain, resulting in water accumulation in the green belt, and it is necessary to use tap water to irrigate the green plants when there is a drought
