Complementing conservation lawn structure

Abstract

The invention provides a complementing conservation lawn structure, and belongs to the technical field of sponge cities. Rainwater wells are arranged on two sides of a lawn, a soil layer, a sand layer, gravels and a complementing conservation device are arranged under the lawn, a plurality of rainwater stopping grids are arranged on two sides of the complementing conservation device, a plurality of water absorption conservation fiber sticks are arranged in the soil layer, a filtration layer is arranged in each rainwater well, and a water pump is arranged at the bottom of each rainwater well; detection ends of temperature and humidity sensors are arranged in the soil layer, and soil temperature signal output ends of the temperature and humidity sensors are connected with a signal input endof a controller; a well lid is arranged on each rainwater well; and communicating pipes are arranged for communicating the soil layer with garbage cleaning cavities. According to the complementing conservation lawn structure disclosed by the invention, the problems that too much water is accumulated, and water drainage is difficult on rainy days when a conventional lawn structure is used can be effectively solved, the situation that root systems of the lawn are rotten by too much accumulated water can be effectively avoided, the development demands of the sponge cities are met, and the complementing conservation lawn structure has the capacity of regulating the temperature and the humidity of earth surface of cities.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to a lawn structure for supplementary conservation. 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". When it rains, absorb water, store water, infiltrate water, filter water, purify water, "release" the stored water and use it when needed. With the development of urbanization, the area of ​​impermeable ground is increasing rapidly, so it is necessary to develop The self-sufficient water supply landscaping and greening system that can make up for these deficiencies can collect rainwater, use rainwater to conserve lawns, improve the utilization rat...
