Laying structure used for garden greenbelt and beneficial to water storage and drainage

Abstract

The invention discloses a laying structure used for a garden greenbelt and beneficial to water storage and drainage. The structure comprises a grit soil layer, a purification water permeation layer, anon-woven fabric layer, a coarse sand isolation layer and a planting soil layer which are laid on base-layer soil from bottom to top in sequence; the planting soil layer is sunken downwards to form awater storage cavity. The planting soil layer is sunken downwards to form the water storage cavity. The laying structure has the functions of storage water, water permeation and purification; the planting soil layer is sunken downwards to form the water storage cavity so that rainwater can be effectively reserved on rainy days, the reserved rainwater can continuously and slowly permeate downwardsin a certain time period, the water content of soil can be increased, so that vegetation on the garden greenbelt is nourished, and groundwater resources can also be supplemented; the rainwater whichpermeates downwards is purified when passing through the water permeation layer, dust and soil can be filtered out, and the pollution of the rainwater surface source to the city environment is reduced.

Description

technical field [0001] The invention relates to the technical field of urban infrastructure, in particular to a garden green space pavement structure that is beneficial to water storage and drainage. Background technique [0002] With the acceleration of urbanization, the underlying surfaces of urban gardens and green spaces are increasingly covered by buildings, structures and various impervious surfaces, preventing rainwater from penetrating into the land and isolating the energy exchange of water vapor in the atmosphere. , will lead to a large amount of rainwater loss, groundwater will not be replenished, and will increase the drainage pressure of municipal drainage pipes. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a garden green space pavement structure that is conducive to water storage and drainage. It not only considers the functions of urban green space water seepage and wate...
