An external wall drainage structure for three-dimensional greening

Abstract

The invention relates to an external wall drainage structure for stereoscopic greening. The external wall drainage structure comprises a drainage main tube and drainage branch tubes. At least part of the drainage main tube is in a continuous broken-line shape, the drainage main tube is arranged between a roof and the ground, and the drainage branch tubes are arranged at positions of break points of the drainage main tube and are each of a U-shaped structure. One end of each drainage branch tube is connected with the drainage main tube, and a planting groove is formed in the upper portion of the other end of each drainage branch tube. Each planting groove comprises a venting isolation plate, a planting soil layer and a plant layer which are arranged in sequence from bottom to top. The bottom of the U-shaped structure of each drainage branch tube forms a water storage groove. The planting grooves and the water storage grooves are fixed to the wall surface through fixing rings. The external wall drainage structure has a series of advantages of saving energy and being environmentally friendly, high in landscape property and stable in structure; the external wall drainage structure can remarkably improve the urban greening coverage after application and forms a unique landscape in dull and monotonous buildings.

Description

technical field [0001] The invention relates to an exterior wall drainage structure, in particular to an exterior wall drainage structure for three-dimensional greening, in particular to an exterior wall drainage structure pipe which can be used for three-dimensional greening on the exterior facade of a building and has a landscape function. Background technique [0002] With the increase of high-rise buildings, the area available for flat land greening is constantly shrinking, resulting in a shortage of land for greening. Therefore, the combination of three-dimensional greening and flat greening has become an important way to rapidly increase the urban green coverage. [0003] Vertical three-dimensional greening is to use the surface area of ​​the medium wall to obtain greening space from the wall to achieve the purpose of saving land, increasing green volume, improving ecological quality, and beautifying the living environment. Vertical greening has the advantages of less ...
