Description

Structure of lawn for supplementing and conserving

Technical Field

The utility model belongs to the technical field of the sponge city, especially, relate to a supply and keep in support lawn structure.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city. The international generic term is "low impact development storm water system construction". The water absorption, water storage, water seepage, water filtration and water purification during raining can release and utilize the stored water when needed, along with the development of urbanization process, the area of impermeable ground is increased at a high speed, so that a system for autonomous water supply beautification and greening, which can make up the defects in the aspects, is necessary to be developed to collect rainwater, and use the rainwater to keep the lawn, the utilization rate of water resources is improved, the integration of water storage, water supplement, drainage, beautification, greening and irrigation functions is realized, the adverse effects of noise and tail gas generated by vehicles on the surrounding environment can be greatly weakened, the effects of more efficient water storage, economic applicability, energy conservation, environmental protection and urban environment improvement are achieved, and the sponge city mainly refers to the city which can have the adsorption capacity like a sponge, absorbs water when in waterlogging and spits water when in drought. Has good elasticity when dealing with environmental changes and good strain capacity in the aspects of dealing with natural disasters and the like. The core of the method is to innovate the urban development mode, so that the city returns to the nature, and an ecological civilized city harmonious with the nature is built. Therefore, the basic principle of constructing the sponge city is to protect the ecology first and improve the scale and quality of the sponge body to the maximum extent, and the construction of the sponge city is to transform the original city infrastructure into the sponge body which absorbs water in waterlogging and spits water in drought. At present, most cities are designed to highlight urban landscapes, green lands are built higher than the surroundings, and cement, asphalt and floor bricks are adopted for paving road surfaces and street surfaces, so that the water permeability is extremely poor. In rainy days, the rainwater flows through the road and flows upwards, but not flows into the green land, so that the green land cannot contain moisture and absorb dust, and the best rainwater irrigation and fertilizer nutrition cannot be obtained. If a large amount of permeable paving materials are adopted to change the permeable pavement and the permeable street surface with the permeable concrete columns, the underground of the city can store considerable underground water for green land irrigation.
