Multifunctional rainwater storage and drainage garden system

Abstract

The invention discloses a multifunctional rainwater storage and drainage garden system, which comprises: a foundation pit, a landscape reservoir and an irrigation reservoir, and a waterproof substrate layer, a coarse gravel substrate layer, a potassium long A stone matrix layer, a quartz sand matrix layer, a mixed matrix layer and a cover layer, the potassium feldspar matrix layer is laid on the coarse gravel matrix layer in a wave shape in the thickness direction, and the quartz sand matrix layer is laid on the coarse gravel matrix layer in the thickness direction It is laid on the potassium feldspar matrix layer in a wave shape, and the filler of the mixed matrix layer is a combination of planting soil and expansive soil. The rain garden system of the present invention has an efficient rainwater filtering effect, can quickly and effectively purify, filter and store rainwater for use when rainwater is insufficient, has multi-functional storage and drainage features, and realizes ecologically sustainable rainwater control Use with rainwater.

Description

Technical field

[0001] The invention relates to the field of rainwater garden systems for collecting and processing rainwater in urban road landscapes, in particular to a multifunctional rainwater garden system for storage and drainage. Background technique

[0002] Rainwater is an important link in the urban water cycle system, and it plays an extremely critical role in regulating and replenishing regional water resources and improving the ecological environment. In the rapid promotion of the urbanization process, the urban form has undergone tremendous changes due to the transformation of land use and the substitution of the hardened surface for the natural surface. Urban rainwater problems have become more prominent, and urban non-point source pollution caused by storm runoff has become Aroused great attention from the international community. The rain garden came into being as a municipal landscape technology to deal with rainwater runoff. Rainwater garden is an effective n...
