Embodiment Construction

[0012] specific implementation plan

[0013] figure 1 It is a schematic cross-sectional view of Embodiment 1 of the present invention. figure 1 Among them, the road 1 is a sidewalk, and the elevation 6 of the top surface of the side stone 2 is not higher than the elevation of the road surface at the junction point, that is, the elevation 6 of the top surface of the side stone is less than or equal to the elevation of the road surface at the junction of the side stone and the road, and the side stone is not higher than the edge of the road. In the prior art, the side stones are generally higher than the road surface. If the side stones are higher than the edge of the road surface, in the embodiment of this patent, a water outlet can be set at the side stones. The usual practice includes partially disconnecting the side stones, That is, the elevation of the local top of the side stone is lowered to the level of the edge of the road surface, or holes are opened on the side ston...

Abstract

The invention belongs to a disconnection structure of a road in a rainwater drainage technology and facility system in the field of constructional engineering. According to the technical scheme, sinking step type slopes are arranged outwards from the curbstone of the road, each step face is provided with a permeable ground, an overflow port is formed in the permeable ground on the lowermost position, the top face elevation of the overflow port is lower than that of the curbstone, the top face elevator of the overflow port is higher than the highest point elevation of the permeable ground on the lowermost position, and the top face elevation of the curbstone is not higher than the road surface elevation of the road at the border point. The road rainwater can seep and be stored and drained through the permeable grounds, and the purposes of rainwater slow drainage and retention are achieved.

Description

technical field [0001] The invention belongs to a rainwater drainage technology and a facility system in the field of construction engineering, in particular to a road drainage structure based on low-impact development. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". [0003] Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. [0004] However, th...
