Description

Rainwater garden type central separation belt drainage structure and construction method Technical Field The application relates to the technical field of road drainage, in particular to a rainwater garden type central separation belt drainage structure and a construction method. Background The rainwater garden is an ecological facility for managing rainwater by utilizing rainwater resources in cities through natural purification, infiltration, storage and other modes, and is generally composed of a manually excavated shallow green land, a sunk green land, a rainwater wetland and the like. The center belt is a safety arrangement provided in the center of a road, and is mainly intended to prevent vehicles from crossing the center belt into an opposite lane and to protect structures in the center belt. Some roads are provided with a rainwater garden in the center of the road, and the rainwater garden is used as a central separation belt, so that on one hand, a part of rainfall is received, the drainage pressure of the road is relieved, the air of the road is regulated, on the other hand, the greening of the road is increased, and the attractiveness of the road is improved. In some cities, rainy seasons and dry seasons are quite clear, so that the soil in the central partition belt is sometimes in a water shortage state, and sometimes has too high water content, so that the growth of plants is not facilitated. Therefore, there is a need to design a drainage structure for a center separator of a rainwater garden type, which reduces the difference between the water content of soil in the center separator in a rainy season and a dry season. Disclosure of utility model In order to reduce the difference of the water content of soil in the central partition belt in rainy seasons and dry seasons, the application provides a rainwater garden type central partition belt drainage structure and a construction method. On one hand, the rainwater garden type central separation belt drainage structure provided by the application adopts the following technical scheme: The rainwater garden type central separation belt drainage structure comprises a belt ditch dug in the center of a road, a filtering assembly and a conveying assembly, wherein the filtering assembly comprises a first filtering plate and a second filtering plate arranged at two ends of the first filtering plate, the first filtering plate is arranged on the ditch wall of the belt ditch, a first planting layer is arranged above the first filtering plate, a water storage area is arranged below the first filtering plate, the first filtering plate is provided with a plurality of first filtering plates which are distributed at intervals along the length direction of the belt ditch, the plate surface of the first filtering plate is arranged in an arc shape, the second filtering plate is arranged in the height direction of the belt ditch in an extending mode, the conveying assembly comprises a plurality of conveying pipes, one ends of the conveying pipes extend to the water storage area, the other ends of the conveying pipes extend into the first planting layer, a plurality of water through openings are formed in the pipe walls of the water storage area and the pipe walls of the first planting layer, one ends of the conveying pipes are filled with conveying sponge, and the conveying sponge extends to the water storage area. By adopting the technical scheme, when the precipitation amount is large, rainwater falls on the first planting layer, one part of the rainwater located on the first planting layer is filtered by the first planting layer and falls into the water storage area, the other part of the rainwater falls to the two ends of the first planting layer and falls between the adjacent second filter plates, the rainwater enters the water storage area for storage after being filtered by the second filter plates, and when the precipitation amount is small, the water in the water storage area is conveyed into the first planting layer by the conveying sponge and the conveying pipe so as to supplement water for the first planting layer. On the one hand, most of water is guided between the adjacent second filter plates when the precipitation amount is large and then is guided into the water storage area, so that the drainage pressure of the first planting layer is reduced, and on the other hand, the conveying assembly is utilized to supplement water for the first planting layer when the precipitation amount is small, so that the difference between the water content of soil in the central dividing belt in rainy season and dry season is reduced. Optionally, the height of the second filter plate is higher than the height of the first planting layer. Through adopting above-mentioned technical scheme, before rivers flow into between the adjacent second filter, utilize the upper portion of second filter to filter rivers, reduce the risk that impurity such as leaf got into between
