Abstract

The invention discloses a shock-resistant water drainage filtration system for a low elevation greenbelt and a construction method. The shock-resistant water drainage filtration system comprises low elevation foundation soil and a water storage well, wherein a shock-resistant layer is installed on a slope of the low elevation foundation soil, the bottom of the low elevation foundation soil is provided with a building stone layer, the surface of the upper portion of the building stone layer is covered by a non-woven fabric base layer, the upper surface of the non-woven fabric base layer is filled with a second filtering layer, the second filtering layer is covered by a sand grain layer, the upper portion of the sand grain layer is filled with a first filtering layer, and the upper surface of the first filtering layer is provided with planting soil. The shock-resistant water drainage filtration system for the low elevation greenbelt decreases urban inland inundation, is simple in structure, quick and convenient to install, convenient to construct, resistant to rainwash, long in service life, good in filtering effect and suitable for urban popularization and use.

Description

technical field [0001] The invention relates to the technical field of garden construction, in particular to an impact-resistant drainage filtering system and a construction method of a sunken green space. Background technique [0002] The sunken green space refers to a public green space whose elevation is lower than the surrounding road surface, also known as low-lying green space. Contrary to the "flower bed", its idea is to use the open space to receive and store rainwater to reduce runoff discharge. Generally speaking, low-lying green spaces have certain requirements for the depth of the depression, and most of the soil quality has not been improved. Compared with the "line" of the shallow ditch of vegetation, the main reason is that the "surface" can receive more rainwater, and the internal plants are mostly native herbs. [0003] At present, the high-speed urbanization process has led to the development of natural watersheds and the destruction of vegetation, while t...
