Embodiment Construction

[0037] The following will combine Figure 1 to Figure 8 , explain in detail the technological principle and specific implementation of the present invention.

[0038] Such as figure 1 As shown, a side-zoning construction system for road rainwater purification in northern coastal saline-alkali areas, its basic process flow and technical principles are as follows:

[0039] During the rainfall period, the rainwater from the roadway 2 enters the roadside ditch 21 in the form of flooding along the cross slope of the road for centralized collection and storage, then quickly transfers to the low potential point in the ditch, and then enters the rainwater distribution device 4 through the curb opening 51, Among them, all the rainwater containing deicing agent in winter is discarded through the drain pipe 42 to the urban sewage system 10 for treatment and discharge, while other rainfalls are settled and pretreated in the diversion device 4, and then all overflow to the filler buffer t...

Abstract

A side zoning construction system for road rainwater purification in northern coastal saline-alkali areas comprises side zoning greenbelts, roadways, roadside ditches of the roadways, permeable sidewalks, rainwater diversion devices, curbs, openings of the curbs, filler buffer grooves, side zoning high-position tree pools and anti-blocking overflow ports. A rainwater diversion device, a filler buffer groove, a side zoning high-position tree pool and an anti-blocking overflow port are arranged in the side zoning greenbelt, the side zoning greenbelt sequentially comprises a plant layer, a soil layer, a filler layer and an artificial aquifer from top to bottom, the top end of the side zoning high-position tree pool is flush with curbs, and the bottom of the side zoning high-position tree pool is connected with the filler layer of the side zoning greenbelt. The anti-blocking overflow port comprises a rainwater grate, a water retaining weir plate, a water inlet groove, a necking type flow guide groove and a net bag. According to the system, the restriction problems of high underground water level, high mineralization degree, serious soil salinization, influence of snow-melting agent spreading in winter and the like on road rainwater pollution control and engineering design construction and implementation of utilization can be solved.

Description

technical field [0001] The invention belongs to the technical field of sponge city construction, and in particular relates to a side-zoning construction system for road rainwater purification in coastal saline-alkali areas in the north. Background technique [0002] my country's two batches of 30 national-level sponge city pilot projects have all passed the expert inspection organized by the Ministry of Housing and Urban-Rural Development. After the acceptance of the pilot project, especially on December 21 this year, the National Housing and Urban-Rural Construction Work Conference made further work arrangements, requiring systematic and comprehensive promotion of sponge city construction. As a special geographical block, the coastal saline-alkali area in the north has always had typical hydrogeological and ecological problems such as the shortage of fresh water resources, high groundwater level and high salinity, serious soil salinization, and harsh plant growth conditions...
