Sponge city road rainwater collection system

Abstract

The application relates to a sponge city road rainwater collection system comprising a road body. First drainage grooves are formed in the two sides of the road body in a length direction. The first drainage grooves are formed in the length direction of the road body. A plurality of rainwater grates are arranged at a top opening of each first drainage groove, a filtering assembly and a purifying assembly are sequentially arranged in each first drainage groove from top to bottom, a water storage tank is arranged below the road body, a plurality of water supply pipes are connected to each firstdrainage groove, the first drainage grooves communicate with the water storage tank through the water supply pipes, and the water storage tank is connected with an exhaust pipe; a water outlet pipe isinserted into the upper surface of the water storage tank and connected with a water pump, an outdoor fire hydrant is arranged on the upper surface of the road body, the bottom end of the water outlet pipe extends to the bottom of the water storage tank, and the top end penetrates the road body to be connected with the outdoor fire hydrant. The sponge city road rainwater collection system has theeffect of collecting and using rainwater.

Description

technical field [0001] The present application relates to the field of sponge city roads, in particular to a rainwater collection system for sponge city roads. Background technique [0002] Sponge city is a new concept of urban construction proposed by the state. The sponge city requires the city to have the functions of infiltration, stagnation, storage, purification, utilization and drainage when it rains. The proportion of road pavement in the whole city is about 30%, and there are problems of runoff pollution and water resource waste caused by rainwater scouring the road surface. Therefore, it is very important to give full play to the role of municipal roads in sponge cities. [0003] The Chinese patent with the notification number CN208965336U discloses a sponge city road, including a roadbed. The middle part of the roadbed is provided with drainage base grooves along the length direction of the roadbed, and partitions are arranged at intervals in the drainage base gr...
