Natural purification drainage system for coastal road construction in sponge-like city

Abstract

The invention provides a natural purification drainage system for coastal road construction in sponge-like city, which is characterized by comprising a split curbstone, a grass planting ditch, a permeable brick pavement walkway, a bioretention zone, a landscape stone dropping weir, a vegetation buffer zone, a gabion retaining wall and gabion slope protection, the invention is mainly used for the coastal road area in construction of sponge-like city, the invention achieves the natural accumulation and natural purification effect of the rainwater, and achieves other effects through a series of natural purification means, such as reducing rainwater pollution, increasing the groundwater level, preventing the road surface gathered water, relieving the pressure of the municipal drainage network,reducing the water and soil loss caused by rain and tidal erosion, the waste of water resources is reduced through the collection of rainwater, thus being energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of rainwater drainage and storage in sponge cities, and in particular relates to a natural purification drainage system used for the construction of coastal roads in sponge cities. Background technique [0002] In the current construction process of traditional urban road drainage facilities, the general drainage method is to set overflow wells and rainwater wells in the green belts on both sides of the road, and collect rainwater directly through the overflow wells and rainwater wells and flow them to municipal rainwater pipes. discharge in the network. The efficiency of this kind of drainage system is low, and when the rainwater is directly discharged into the natural water body without treatment, it will cause serious water pollution, and this kind of drainage system needs to lay a large number of pipe networks and overflow wells in the early construction process, increasing the Costly and unsatisfactory...
