Road rapid infiltration and water storage green belt

Abstract

The invention relates to a road rapid infiltration and water storage green belt. The green belt is arranged in the middle or on the two sides of a road and comprises a plurality of evenly-distributedplant planting pits, a plurality of rapid infiltration pipes evenly distributed around each plant planting pit, and rainwater wells; a planting layer is formed between the plant planting pits and therapid infiltration pipes, the bottom of the planting layer is provided with a water storage layer, and the planting layer and the water storage layer are connected through the rapid infiltration pipes; overflow pipes are arranged in a subgrade between the planting layer and the rainwater wells, one ends of the overflow pipes communicate with the upper portions of the rainwater wells, and the otherends of the overflow pipes are located on the lateral upper portion of the water storage layer; water collecting areas are arranged on the two sides of the bottom of the water storage layer correspondingly and communicate with the rainwater wells through communicating pipes, and the tops of the communicating pipes and the top of the water storage layer are located on the same horizontal plane; and the rainwater wells are partitioned through partition plates, and the bottoms of one ends of the rainwater wells are connected with drainage pipes to be connected with an external drain system. Theroad rapid infiltration and water storage green belt is simple in structure, low in cost and obvious and practical in effect.

Description

technical field [0001] The invention relates to the technical field of municipal greening, in particular to a road rapid percolation and water storage green belt. Background technique [0002] Roads are divided into the following five grades according to their functions and traffic volumes: 1. Expressways 2. First-class roads 3. Second-class roads 4. Third-class roads 5. Fourth-class roads. Generally, provincial roads use Class II, III, and IV roads, and their widths vary according to the design speed. The greening along the road is to add organic natural color to the inorganic road, and it is the main factor of the environmental landscape. The landscape design of greening along the road is not only designed as a divider and a shelter for the carriageway, but also to meet the overall landscape needs and safety along the road and the expressway. Good greening design can not only reduce the impact of roads on the environment, but also maintain the ecological balance of the f...

Problems solved by technology

[0003] At present, the green belts in China have only one layer of planting layer, and the water storage rate of the soil is very poor. In case of heavy rain or heavy rain, the green belt cannot store water well, and this will cause a lot of runoff; if the roadbed is waterproof No, seeping rainwater will soak the roadbed, which will have great harm to the service life of the road

Moreover, the existing green belts in China must often water the plants in the green belts, which greatly increases the cost of road construction and use.
