Ecological trail structure of sponge city

Abstract

The invention provides an ecological footpath structure of a sponge city. The ecological footpath structure comprises footpath foundations, a drainage pipeline and communicating pipelines; along a design route of a gardening ecological footpath, the drainage pipeline is pre-buried in soil; the two ends of the drainage pipeline are open, or placed in a pond or a reservoir; a siphoning drainage mechanism is fixedly connected to each of the inner ends of three circular through holes through a rubber sealing ring. During using under an ordinary raining condition, rainwater drops onto a pervious concrete block A, the rainwater quickly penetrates through the pervious concrete block A, runs through a supporting assembly adopting a honeycomb structure and then penetrates into and gathers in a pervious concrete block B due to the characteristics of the pervious concrete block A, and the rainwater gathering in the pervious concrete block B eventually flows into a water storage chamber through acommunicating hole for collection and storage, so that a large amount of rainwater is not left on the surface of the pervious concrete block A; therefore, the ecological footpath avoids occurrence ofthe situation that walking is affected by muddiness and large-area water accumulation.

Description

technical field [0001] The invention belongs to the technical field of sponge city ecological trails, and more specifically relates to the ecological trail structure of sponge cities. 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] The sponge city ecological trails in the prior art mostly use bricks with holes or stone slabs or cement slabs directly laid on the compacted original soil layer. The ecological trails of this design have the following shortcomings when used in rainy conditions: the rain on the ecological trails cannot be removed quickly , there is a lot of residual rainwater, and it is easy to cause a piece of mud when walking, which ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides an ecological trail structure of the sponge city to solve the problem that rainwater cannot be removed quickly on the existing ecological trails, and there is a lot of residual rainwater, which is easy to cause a piece of mud when walking, making it difficult to walk in the future; rainy weather conditions Under the environment, the soil around the ecological trail is infiltrated by rainwater, and the surrounding water and soil loss is serious, and local subsidence and subsidence are prone to occur in the follow-up, which affects the use of the problem
