Problems solved by technology

The water guide device can collect rainwater to a certain extent and accelerate the infiltration of rainwater. However, if the above water guide device is used in areas with large rainfall, all the rainwater will be discharged to other areas by the drainage device, causing water accumulation in other areas, etc. Happening

[0044] Please refer to figure 1 with figure 2 As shown, this embodiment provides a sponge urban drainage structure 100, which is arranged on a soil layer 140. The sponge urban drainage structure 100 includes a permeable surface layer 110, a drainage permeable layer 120 and a reservoir which are sequentially arranged from top to bottom. 130, that is, a reservoir 130 is provided on the soil layer 140, a drainage permeable layer 120 is provided on the reservoir 130, and a permeable surface layer 110 is provided on the drainage permeable layer 120. A plurality of overflow pipes 150 are arranged through the water-permeable surface layer 110, that is, one end of the overflow pipe 150 extends out of the water-permeable surface layer 110 and communicates with the surface of the water-permeable surface layer 110, and the other end extends into the drainage permeable layer 120 and is connected to the permeable layer 120. Connected, the perforated blind pipe 160 is buried in the drainage ...

[0050] Please refer to image 3 with Figure 4 As shown, this embodiment provides a sponge city water circulation system 001, which includes a sponge city percolation structure 400 disposed on a soil layer 140, and a clean stagnation structure 200 and a water use structure 300. The sponge city percolation structure 400 and the first The structure of the sponge city drainage structure 100 in one embodiment is substantially the same. The sponge city drainage structure 400 is connected to the clean stagnant structure 200, and the clean stagnant structure 200 is connected to the water structure 300. The sponge city seepage and drainage structure 400 is used to allow rainwater to penetrate into the soil or drain rainwater into the stagnant structure 200. The stagnant structure 200 is used to purify the accumulated water, and the water structure 300 is used to output the purified water. use.

Abstract

The invention provides a sponge city drainage structure and a sponge city water circulation system, and relates to the technical field of sponge cities. The sponge city water circulation system comprises a sponge city drainage structure, a filtering structure and a water utilization structure which are communicated in sequence, wherein the water permeating surface of the sponge city drainage structure is provided with a plurality of overflow pipes in a penetrating mode. A holey blind tube is placed in the drainage penetrated layer in an embedded mode. Each overflow pipe placed at one end of the drainage penetrated layer is connected with the holey blind tube. The other end of the holey blind tube is connected to the filtering structure. When the rainfall is low, the rainwater enters into the reservoir to be stored and then penetrates through the soil layer. When the rainfall is high, the water level of the reservoir rises above the holey permeable blind tube and the rainwater is output to the filtering structure through the holey blind tube to be ecologically purified, and then the rainwater is extracted by the water utilization structure. The water penetration effect of the sponge city drainage structure is good. The rainwater infiltrates to underground or is drained to the external part which avoids causing the ponding. The sponge city water circulation system is capable of evenly achieving comprehensive and effective rain flood managing for different rainfall.

Description

Technical field [0001] The invention relates to the technical field of sponge cities, in particular to a sponge city seepage structure and a sponge city water circulation system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's "flexibility" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called "water resilient city", an international term For "low impact development rainwater system construction". Its main function is to absorb water, store water, seep water, and purify water when it rains, and "release" and use the stored water when needed. [0003] (1) Water seepage effect of ecological sponge city [0004] With the advancement of urbanization, urban natural ecology is also facing severe imbalances. The urban pavement is hardened and impervious material paving is everywhere, which has changed the original natural ecological background and hydr...
