Embodiment 1

[0029] like figure 1 As shown, the seepage and flood drainage system based on the sponge city includes a constructed wetland 5, the constructed wetland 5 is connected to the buffer pool 3 through the second water pipe 4, and the buffer pool 3 is connected to the river channel 1 through the first water pipe 2; the constructed wetland 5 is set in a park or In other environments to be greened, this system has been built and the environment has been beautified.

[0030] like figure 2 As shown, a disinfection layer 54, a first isolation layer 53, a water storage layer 52 and a planting layer 51 are sequentially arranged in the constructed wetland 5 from bottom to top; wherein the planting layer 51 is mainly filled with soil, and planting layers 51 are planted with Water plants 58; the matrix in the aquifer 52 is mainly coarse sand, and the coarse sand preferably has a diameter of quartz sand between 1mm-8mm; the first isolation layer 53 is provided with a mud-blocking plate for b...

Embodiment 2

[0037] This embodiment is a further improvement on the seepage and flood drainage system on the basis of Embodiment 1. For details, refer to image 3 , the seepage and flood drainage system based on the sponge city also includes an intercepting device 11 for intercepting river garbage, preventing large pieces of garbage in the river 1 from entering the first water pipe 2 to cause blockage of the water pipe and affecting the normal operation of the system.

[0038]The intercepting device 11 is set as a hollow triangular prism, a water inlet 111 and an installation hole 112 surrounding the water inlet 111 are arranged on one side of the triangular prism; a grid plate 113 is arranged on one side of the triangular prism. During implementation, the water inlet 111 of the intercepting device 11 is docked with the first water pipe 2, and the intercepting device 11 is fixed on the river channel wall by using the installation hole 112, so that the side with the grid plate 113 faces away...

Embodiment 3

[0042] This embodiment is a further improvement on the constructed wetland on the basis of Embodiment 1 and Embodiment 2. For details, refer to figure 1 and figure 2 , the constructed wetland 5 also includes a water collection layer 55 arranged below the disinfection layer 54, the water collection layer 55 is formed by stacking several empty boxes 551, and the surface of the empty boxes 551 is provided with through holes, one of which is close to the bank of the constructed wetland 5 A water pump 59 is arranged in the empty tank 551; a second isolation layer 56 is arranged below the water collecting layer 55, and the structural materials of the second isolation layer 56 and the first isolation layer 53 are the same. A large number of cavities formed by the water collection layer 55 enable it to accumulate a large amount of water resources, which can quickly infiltrate in rainy seasons and be absorbed by upper vegetation in dry seasons, ensuring the ecological balance of the c...

Abstract

The invention discloses a water seepage and flood drainage system based on a sponge city. The water seepage and flood drainage system comprises an artificial wetland, wherein the artificial wetland is connected with a buffer tank by virtue of a second water pipe, and the buffer tank is connected with a river by virtue of a first water pipe; the artificial wetland is successively provided with a sterilizing layer, a first isolation layer, a water storage layer and a planting layer from bottom to top; soil is arranged in the planting layer, and emergent aquatic plants are planted on the planting layer; coarse sand is arranged in the water storage layer; a mud separation plate for blocking mud and sand is arranged in the first isolation layer, and the mud separation plate is wrapped with geotechnical cloth; and a plurality of volcanic rocks are arranged in the sterilizing layer. The water seepage and flood drainage system based on the sponge city solves the problem that the rainy and flood water is difficult to seep and accumulate for use; and meanwhile, the system can effectively alleviate the flood leak pressure of a river, can improve the convenience of the municipal water application and can realize a function of seeping, collecting, purifying, storing and utilizing the river water and rainy water.

Description

technical field [0001] The invention relates to the field of rainwater treatment, in particular to a seepage and flood drainage system based on a sponge city. Background technique [0002] With the significant acceleration of the urbanization process in our country, the continuous expansion of the city scale, the intensification of the urban ground hardening, resulting in the increase of the rainwater runoff coefficient and the acceleration of the confluence, in case of heavy rain, the road surface is prone to water accumulation, and in severe cases, it is easy to cause urban road traffic paralysis and casualties. [0003] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In recent years, with the frequent occurrence of extreme weather, waterlogging is common in many cities in my country after heavy rainfall. The concept of "sponge city" has attracted more and mor...
