Sponge city construction based road rainwater collection and drainage system

Abstract

The invention relates to the field of sponge city construction, in particular to a sponge city construction based road rainwater collection and drainage system. The sponge city construction based roadrainwater collection and drainage system comprises a roadway area, a green belt area, a pavement area and a back green area which are respectively arranged on the road, a rainwater collecting deviceand a roadway drainage shaft which is used for draining rainwater collected through the rainwater collecting device are arranged in the roadway area, a soakage pit used for infiltrating rainwater below the ground is arranged in the green belt area, an overflow rainwater well, a rainwater collecting module, a water jet irrigation device and a main rainwater delivery pipeline are arranged in the back green area, and the overflow rainwater well, the rainwater collecting module, the water jet irrigation device and the main rainwater delivery pipe are mutually communicated with the rainwater collecting device, the roadway drainage shaft and the soakage pit through a rainwater collecting pipe. By the arrangement, the rainwater can be effectively collected and timely dredged and utilized, the problem about urban road waterlogging is greatly alleviated, and the system is energy saving and environment friendly and can be widely promoted.

Description

technical field [0001] The invention relates to the field of sponge city construction, in particular to a highway rainwater collection and discharge system based on sponge city construction. Background technique [0002] With the rapid development of my country's modern economy and the intensification of urbanization, my country's expressway industry has also achieved unprecedented development. The mileage of my country's expressways ranks first in the world. At that time, the road surface could not absorb and seep water in a timely and effective manner, which caused the phenomenon of urban road accumulation, which brought great inconvenience to urban traffic, and also caused a large amount of rainwater loss. [0003] Sponge city refers to that by strengthening the management of urban planning and construction, giving full play to the role of buildings, roads, green spaces and water systems in absorbing, storing and slowing down rainwater, effectively controlling rainwater ru...
