Road green belt water collecting system and construction method

Abstract

The invention relates to the field of urban road construction, and discloses a road green belt water collection system and a construction method. The road green belt water collection system comprises a water collection pool arranged at the lower end of a green belt, a water permeable plate is arranged at the top end of the water collection pool, a water seepage mechanism is arranged on the upper layer of the water permeable plate, the water seepage mechanism comprises a gravel layer and a large-particle gravel layer; a water outlet pipe is arranged in the center of the water collection pool and penetrates through the water seepage mechanism to be connected with a ground irrigation device; road drainage ditches are arranged on the two sides, close to a road, of the water collection pool and connected with the water collection pool through flow guide pipes. According to the road green belt water collection system, construction can be conducted on the constructed green belt, rainwater can be fully utilized for irrigating the green belt, growth of plants in the green belt is not affected, water resources are effectively saved, and the greening effect is guaranteed.

Description

technical field [0001] The invention relates to the field of urban road construction, in particular to a road green belt water collection system and a construction method. Background technique [0002] The green belt has the function of beautifying the city, eliminating the visual fatigue of drivers, and purifying the environment. It can block dust, reduce noise, absorb harmful gases, and release oxygen. At the same time, it can separate traffic and reduce traffic accidents. It has safety functions. It can be seen that green belts are playing an increasingly important role in modern urban construction. However, after the traditional green belt is planted, it needs to be watered irregularly. The existing watering method usually uses the road sprinkler to water, which is costly and dangerous to water on both sides of the road. In addition, when it rains, the rainwater flows through the road and the drainage pipe The rainwater is not fully utilized, resulting in a waste of wat...

AI Technical Summary

Problems solved by technology

[0004] But there is following defect in above-mentioned prior art scheme: can't use above-mentioned technology for the green belt that has been built, if re-build green belt can cause the waste of resource and the raising of cost; The water seepage layer will hinder the growth of plants with well-developed root systems. The longer the planting time, the larger the space required for root growth. The sand and gravel structure of the water seepage layer affects the growth of plant roots, thereby affecting the growth of green plants; within the scope of the green belt Reservoirs are all laid, and too many reservoirs increase the cost and cause waste of resources
