Embodiment Construction
[0023] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.
[0024]A road green belt system for drainage and water retention, comprising a ground part 1 , a piping system 2 and a water storage tank 3 . The ground part 1 is generally planted with street trees 4 in the middle, and bushes 5 are distributed on both sides. The pipeline system 2 can be used to collect rainwater from the road surface, and is connected to the water storage tank 3 through the upper and lower channel ports 8 and 10, and the lower part is connected to the urban drainage pipe network. The water storage tank 3 is arranged directly under the bushes 5, and the specific depth is mainly determined by the extension depth of the roots of the bushes 5, and the width is also determined by the width of the green belt and the planting width of the bushes 5 on the side of the road. , to avoid affecting the growth of the roots of the street trees 4....

The invention discloses a road green belt system for drainage and water retention, comprising a ground part, a pipeline system and a water storage tank. The ground part includes street trees and bushes distributed on both sides of the street trees, the water storage tank is located directly under the bushes, and the piping system is located outside the water storage tank, including rainwater collection pipes for collecting road surface water, and urban A drainage pipe connected to the drainage pipe network, the lower end of the rainwater collection pipe is connected to the upper channel port provided on the water storage tank, one end of the drainage pipe is connected to the lower channel port provided on the water storage tank, and the other end is connected to the urban drainage pipe network. The invention integrates drainage and water retention, and the collected rainwater will be preferentially collected in the water storage tank, especially in the face of urban rainstorm, the water storage space below it can store a part of the water, and appropriately reduce the drainage pressure of the urban pipe network; , the water in the water storage tank can be transported through the soil in the cuboid cavity to ensure the water demand of the trees.
Description
technical field [0001] The invention belongs to the field of rainwater stagnation, storage, filtration and drainage in urban road green belts, and relates to a road green belt stagnation, storage, filtration and drainage system. Background technique [0002] Green belts are often set on both sides of the road, generally consisting of street trees, short shrubs and lawn grass, which have the functions of greening environmental protection, fresh air, and beautifying the urban environment. The conventional road green belt is higher than the ground, and the water holding capacity is poor in case of heavy rain, causing soil erosion and increasing the pressure on the urban drainage network; some green belts are designed to be concave, and the difficulty of rainwater drainage in case of heavy rain will cause the green belt to accumulate Water; under drought conditions, it is difficult to replenish water in green belts, and tree maintenance requires manpower and material resources. ...
