Embodiment 1

[0040] This embodiment is a kind of roof greening system, comprises the base layer 19 that is arranged on building structure layer 21 top, and base layer 19 comprises roof screed, waterproof layer, thermal insulation layer, surface course, and base layer 19 top is provided with protective layer 18 ( 18), the protective layer 18 includes an anti-seepage layer and a root-separating layer, a storage and drainage module 17 is arranged above the protective layer 18, a water permeable cloth 16 is arranged above the water storage and drainage module 17, and planting soil is laid on the top of the water permeable cloth 16 15.

[0041] The storage and drainage module 17 is located above the root layer. The storage and drainage module 17 usually adopts a storage and drainage module 17 of 500mm*500mm. A 20mm overflow port is left on the top, and when the rainwater is stored too much, the rainwater will be discharged through the overflow port.

Embodiment 2

[0043] Based on Embodiment 1, the storage and drainage modules 17 of this embodiment are arranged in blocks, and an overflow port is provided on the top of each storage and drainage module 17; a drainage ditch 14 and a rainwater outlet 11 are provided on the building structure layer 21; The edge of the planting soil 15 is provided with a dedicated drainage groove 12 communicating with the drainage ditch 14 .

[0044] The drainage ditches 14, rainwater outlets 11 and special drainage grooves 12 provided in this application can all realize rapid discharge of water accumulated on the roof, avoiding damage to plants caused by accumulation in the planting soil 15, and at the same time cooperate with the use of the storage and drainage module 17 to ensure moisture needed by plants.

Embodiment 3

[0046]Based on Embodiment 1, a retaining wall 22 is arranged around the planting soil 15 of this embodiment, and a drainage hole 23 is arranged on the retaining wall 22 .

[0047] By arranging the retaining wall 22 around the planting soil, the stability of the planting can be enhanced, and the surroundings of the planting soil can be prevented from slipping. Meanwhile, the drainage holes 23 provided on the retaining wall 22 further enhance the drainage function of the green roof system. The probability of water accumulation on the roof caused by heavy rain is reduced, the protection of the roof is realized, and the quality of life of the people is improved.

Abstract

The invention discloses a roof greening system, relates to the technical field of greening systems, solves the problems that in the prior art, a roof greening system can cause roof water seepage, rainwater cannot be reasonably utilized, and plants are drowned, and comprises a foundation layer arranged above a building structure layer, the base layer comprises a roof leveling layer, a waterproof layer, a heat preservation layer and a surface layer, a protection layer is arranged above the base layer and comprises an impermeable layer and a root isolation layer, a water storage and drainage module is arranged above the protection layer, water-permeable working cloth is arranged above the water storage and drainage module, and planting soil is laid above the water-permeable working cloth; by arranging the protection layer, water can be prevented from being poured from planting soil or water gathered in the planting soil in rainy days can be prevented from permeating into the building structure layer, a good waterproof effect can be achieved through the waterproof layer in the protection layer, and meanwhile the root system of the planted plant is prevented from growing to the building structure layer through the root separation layer in the protection layer; therefore, the effect of protecting the building is achieved.

Description

technical field [0001] The present invention relates to the technical field of greening systems, more specifically to the technical field of roof greening systems. Background technique [0002] Roof greening can be broadly understood as a general term for gardening and planting trees and flowers on the roofs, terraces, roofs, balconies or large artificial rockeries of various ancient and modern buildings, structures, city enclosures, bridges (overpasses). [0003] 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...
