Abstract

The invention discloses a sponge urban road rainwater infiltration system and a construction method thereof. The sponge urban road rainwater infiltration system comprises a rainwater infiltration layer, a purification layer and an underground water collecting pipe. The purification layer is located between the rainwater infiltration layer and the underground water collecting pipe. The rainwater infiltration layer sequentially comprises a water penetration brick layer, a sponge filter layer, a second collecting layer, a concrete base layer and a first collecting layer from top to bottom. Rainwater purification devices are arranged in the purification layer and connected with the rainwater infiltration layer and the underground water collecting pipe through flow guide pipes. The construction method of the system includes construction preparation, underground water collecting pipe laying, purification layer construction and rainwater infiltration layer construction. The system is high in practicality, the construction method is simple, the construction requirements of rainwater infiltration systems of different roads can be met, the drainage effect of urban road rainwater is improved, the water drainage pressure of municipal sewer lines is effectively relieved, meanwhile, purified rainwater can be supplied for life use according to different purification degrees and can also be used for irrigation, and water resources are greatly saved.

Description

technical field [0001] The invention relates to a sponge city road rainwater infiltration system and a construction method thereof. Background technique [0002] In urban construction, with the increase of impervious ground in urban areas, the runoff of rainwater is also increasing year by year. This not only increases the pressure on the urban drainage system and destroys the urban ecology, but also wastes precious rainwater resources in vain. [0003] In recent years, with global warming and frequent occurrence of extreme weather, severe waterlogging has occurred in some densely populated cities, which not only affects people's production and life, but also seriously threatens life safety. The rainwater collection system in the prior art can only realize the collection of rainwater, does not have the function of drainage and discharge, and can not purify the rainwater at the same time. Contents of the invention [0004] The purpose of the present invention is to provid...
