A special rapid drainage and irrigation system for urban roads

Abstract

The invention discloses a special rapid drainage system for an urban road, and belongs to the technical field of urban road drainage and rainwater utilization. Water collecting side ditches are formed under flat road kerbs along the two sides of a motorway of the road; gap cover plates are covered on the water collecting side ditches; declogging wells are formed every 6-7 meters along the water collecting side ditches, and each declogging well communicates with the corresponding water collecting side ditch for precipitating first-stage rainwater; a declogging well cover plate is covered on each of the declogging wells; a water seepage and storage tank is arranged on one side of each of the declogging wells in a corresponding manner, and the water seepage and storage tanks are arranged on a side separating band of the road; each of the declogging wells and the corresponding water seepage and storage tank are connected through an oblique collecting pipe, and a sewage intercepting basket is arranged at an opening, connected with the corresponding declogging well, of each collecting pipe; and overflow openings are formed every 31 meters in each of the water collecting side ditches. According to the special rapid drainage system for the urban road disclosed by the invention, under the premise that a conventional road structure is not changed, the purpose of rapidly draining a rain runoff of the urban road can be realized, and the special rapid drainage system disclosed by the invention has the characteristics that the construction cost is low, and the safety of the urban road structure is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of urban road drainage and rainwater utilization, and in particular relates to a special rapid drainage and irrigation system for urban roads. technical background [0002] In recent years, road ponding caused by heavy rainfall has been a chronic disease that affects pedestrian travel and even endangers urban traffic safety. It is common in cities in my country; as an important part of urban underlying surfaces, asphalt concrete is mostly used for existing urban road surfaces Or cement concrete and other impermeable pavements have the characteristics of fast production and confluence. When short-duration heavy rainfall occurs, water accumulation is prone to occur, causing waterlogging disasters in the urban road system. [0003] The existing urban roads are mainly collected by point-type stormwater outlets, and then quickly discharged to the municipal sewage system through pipes and rainwater wells. The desig...

AI Technical Summary

Problems solved by technology

The existing road drainage system has the limitations of low rainwater collection efficiency, high correlation between system elements, and great influence of road longitudinal slope while solving the basic drainage needs of the road.

[0004] Especially for the existing urban roads in urban built-up areas, in order to cope with the threat of water accumulation and waterlogging, the traditional reconstruction method is often to increase the diameter of drainage pipes, which requires secondary excavation of the roads, which has long construction period, high consumption of manpower and material resources, and Disturbing residents, affecting normal traffic flow, etc.
