Ditch cover and green road reconstruction method

Abstract

The invention discloses a ditch cover and a green road reconstruction method. The ditch cover (9) is composed of a cover plate (10) and a water inlet pipe (11). The ditch cover (9) is laid at an original side ditch (2) of a road when the road is reconstructed, then a layer of geotechnical cloth (13) is laid on the cover plate (10) of the ditch cover (9), the upper surface of the geotechnical cloth (13) is filled with planting soil (7), turf (6) is planted at the top of the planting soil (7), and an inlet in the top of the water inlet pipe (11) of the ditch cover (9) is higher than the top of the planting soil (7). According to the ditch cover and the green road reconstruction method, the drainage requirement of the original side ditch is not lowered; rainwater infiltrates into the turf and the planting soil and is converged into the original side ditch through water leakage holes in the ditch cover to be drained when rainfall is small; part of rainwater is converged into the original side ditch through seepage when the rainfall is large, another part of the rainwater is introduced into the original side ditch through the water inlet pipe, and the other part of the rainwater flows automatically along the surface of the green side ditch to be drained.

Description

technical field [0001] The invention relates to a road drainage facility reconstruction, in particular to a ditch cover and a road green reconstruction method, belonging to the technical field of road drainage and road reconstruction engineering. Background technique [0002] Both pavement structure and drainage facilities are important components of roads. Open ditches are mostly used for road drainage, and side ditches are usually made of masonry materials such as concrete or masonry rubble. The pavement structure can generally be divided into concrete pavement, asphalt pavement, and gravel pavement. [0003] In the past, limited to the level of economic development, especially the low-grade roads in some rural areas and economically underdeveloped areas, the road surface was mostly made of gravel, slag and other materials, and the side ditches were mostly open ditches built by masonry, and some even only It is called "earth ditch". Such roads generally have problems suc...

Problems solved by technology

[0005] Although the traditional reconstruction method can improve the unfavorable conditions of low-grade roads, such as "gray in sunny days and mud in rainy days", when faced with some special environmental conditions, such as scenic spots and ecological protection areas, the traditional road reconstruction methods are ineffective in environmental protection, landscape, etc. Difficult to achieve satisfactory results
