Roof anti-seepage greening engineering structure

Abstract

The invention discloses a roof anti-seepage greening engineering structure. The roof anti-seepage greening engineering structure comprises a plurality of greening anti-seepage structures arranged on aroof platform; each greening anti-seepage structure comprises an anti-seepage filling layer, an anti-seepage film, a filter hole plate and a soil layer which are sequentially arranged from bottom totop, a water passing cavity is formed between each anti-seepage film and the corresponding filter hole plate and internally provided with a plurality of fixing support pieces, and the upper and lowerends of each fixing support piece are connected with the corresponding anti-seepage film and the corresponding filter hole plate respectively; each water passing cavity is internally provided with a water passing pipeline, each water passing pipeline is communicated with a plurality of three-way pipes, one end of each three-way pipe is communicated with the corresponding water passing pipeline, the other two ends of each three-way pipe are fixedly provided with micro-pore nozzles, and the two ends, provided with the corresponding micro-pore nozzles, of each three-way pipe are located in the corresponding soil layer. Two problems are solved that drainage is not easy in roof greening engineering, and vegetation on a roof is difficult to irrigate and cannot obtain enough water.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a roof anti-seepage greening engineering structure. Background technique [0002] Roof greening can increase the area of ​​urban green space and improve the deteriorating human living environment space; improve the urban high-rise buildings and improve the status of natural land and plants replaced by the hard pavement of many roads; improve the excessive deforestation of natural forests, various exhaust gases The urban heat island effect and sandstorms caused by pollution are harmful to human beings; it is of great significance to open up human green space, build garden cities, improve people's living conditions, improve the quality of life, and beautify the urban environment and improve ecological effects. For example, the Chinese patent with the patent number CN201821626047.9 discloses a water-saving ecological roof greening system, including: multiple planting areas, wate...

AI Technical Summary

Problems solved by technology

[0003] The purpose of this invention is to provide a kind of roof anti-seepage greening engineering structure, one is to solve the roof greening engineering, because the lower layer of the soil is the roof, when there is too much rain, too much moisture can not seep into the ground like other ground cover structures, But too much is accumulated on the roof, if it cannot be discharged in time, it will easily cause the rot of the vegetation, and it will also cause greater damage to the anti-seepage layer of the roof; the second is to solve the difficulty of irrigating the vegetation on the roof. Spray irrigation is carried out on the surface of vegetation, but the water on the roof is easy to lose, resulting in poor vegetation irrigation and insufficient water for vegetation
