Description

Technical Field

[0001] The invention belongs to the technical field of urban municipal facilities, and in particular relates to a connected high-efficiency drainage tree pool structure. Background Art

[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 a "water elastic city". When it rains, it absorbs water, stores water, infiltrates water, filters water, and purifies water. When needed, the stored water is "released" and used. With the development of urbanization, the area of ​​impermeable ground is growing rapidly. Therefore, it is necessary to develop an autonomous water supply and beautification system that can make up for these deficiencies, collect rainwater, and use rainwater to conserve lawns, improve the utilization rate of water resources, and realize the integration of water storage and replenishment, drainage, beautification and irrigation functions. It can greatly reduce the adverse effects of noise and exhaust gas generated by vehicles on the surrounding environment, and achieve more efficient water storage, economic applicability, energy conservation and environmental protection, and improve the urban environment. Sponge city mainly refers to the city's ability to absorb water like a sponge, absorbing water during floods and spitting water during droughts. It has good "elasticity" in response to environmental changes and good resilience in response to natural disasters.

[0003] Its core is to innovate the urban development mode, let the city return to nature, and build an ecological civilization city in harmony with nature. Therefore, the basic principle of building a sponge city is to give priority to protecting the ecology and maximize the scale and quality of the "sponge body". Building a sponge city means transforming the original urban infrastructure into a "sponge body" that absorbs water during floods and spits out water during droughts.

[0004] At present, in order to highlight the urban landscape, most cities not only build green spaces higher than the surrounding areas, but also use cement, asphalt and floor tiles for pavement and street paving, which have extremely poor water permeability. When it rains, the rain often flows to the road and street instead of to the green space, making it impossible for the green space to retain moisture and absorb dust, and it cannot get the best rainwater irrigation and fertilizer nourishment. If a large amount of permeable paving materials are used to make it a permeable road surface and permeable street surface with permeable concrete columns, the city's underground will be able to store a considerable amount of groundwater for green space irrigation. Ecological tree pools are a top priority in urban greening and urban planning, so it is very beneficial to recycle, purify and store rainwater through ecological tree pools. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides an interconnected high-efficiency drainage tree pool structure, which can effectively solve the problems of rainwater resource waste and urban waterlogging while greening. The high-efficiency drainage tree pool structure can recycle, store and discharge excess rainwater, thereby achieving more efficient water storage, economic applicability, energy saving and environmental protection, and improving environmental effects.

[0013] The beneficial effects of the present invention are that rainwater is recycled, purified and stored through ecological tree pools, which can effectively solve the problems of rainwater resource waste and urban waterlogging while greening, and has good economic and social benefits. When light rain occurs, the rainwater is purified and stored in a clean water conservation chamber to achieve rainwater purification and storage. At this time, the water storage function is played. If heavy rain occurs, the rainwater is discharged from the storm drain pipe. At the same time, the emergency seepage net can quickly and efficiently discharge the accumulated water, effectively solving the problem of ground water accumulation in the rainy season. At this time, the drainage function is played, and the interconnected high-efficiency drainage tree pool structure can recycle, store and discharge excess rainwater, achieving the effects of more efficient water storage, economic applicability, energy saving and environmental protection, and improvement of the urban environment.
