Lawn field convenient for water seepage and construction method

Abstract

The invention discloses a lawn field convenient for water seepage. The lawn field comprises a rammed plain soil layer, a base gravel layer located on the rammed plain soil layer and a water seepage layer located on the base gravel layer. A lawn surface layer is arranged on the water seepage layer, a blind pipe is buried in the basic gravel layer, and a plurality of hollow water seepage pipes are pressed into and inserted into the rammed earth layer and are evenly arranged at intervals. One end of each water seepage pipe is an insertion end, and the other end is a drainage end. The insertion ends of the water seepage pipes are inserted into a loose water seepage layer of the rammed earth layer, and the drainage ends of the water seepage pipes are flush with the surface of the rammed earth layer. The lawn field has the characteristic of reducing the drainage pressure of a municipal rainwater pipe network.

Description

technical field [0001] The invention relates to the technical field of lawn fields, in particular to a lawn field and a construction method that are convenient for water seepage. Background technique [0002] With the development of industrialized cities and the increase of urban traffic vehicles, they are highly transparent to visible light from solar radiation, and highly absorptive to long-wave radiation emitted by the earth, which can strongly absorb infrared rays in ground radiation, causing the earth's temperature to rise. Rise, resulting in a greenhouse effect, increased global rainfall, and redistribution of precipitation. For this reason, the state proposes to build a "sponge city", the purpose of which is to give priority to retaining limited rainwater when improving the urban drainage system, give priority to more use of natural power to drain water, and build an environmentally friendly sponge that accumulates naturally, infiltrates naturally, and purifies natura...

AI Technical Summary

Problems solved by technology

[0003] At present, the lawn site includes natural lawn layer, planting soil layer, crushed gravel layer and plain soil layer from top to bottom. Among them, dead pipes are buried in the crushed gravel layer, and the dead pipes are connected to the municipal rainwater pipe network, and the rainwater falls on the lawn site. When the rainfall is too high, the rainwater goes deep into the crushed gravel layer from the natural lawn layer and the planting soil layer, and then flows into the municipal rainwater pipe network from the crushed gravel layer through the blind pipe. In the rainwater pipe network, it will lead to excessive pressure on the municipal rainwater pipe network, so there are certain improvements
