A green roof with unit modular pitched roof

Abstract

The invention provides a unit modular green roof with a sloping roof surface, comprising a unit module outer frame having a bottom plate and a plurality of side plates fixedly connected with the bottom plate. The unit module outer frame is respectively provided with water discharge holes in the lower parts of two side plates perpendicular to the water flow direction, the inner walls of the lower parts of the side plates of the unit module outer frame are fixedly connected with a plurality of bracket plates, the bracket plates are not in contact with the bottom plate of the unit module outer frame, a water drainage plate with a plurality of water drainage holes is supported on the bracket plates, the lower part of the unit module outer frame and the lower surface of the water drainage plateform a reservoir, the geotextile is laid on the water drainage plate, a plantation soil layer is arranged on the geotextile, the upper part of the plantation soil layer is provided with geocells, roof plants are planted in the plantation soil layer allocated by the geocells, and a drainage belt is interposed between the reservoir and the plantation soil layer below the roof plants. The application is based on the unit modular construction, which improves the construction speed of the green roof and solves the problems that the plantation soil is easy to slide along the sloping roof surface and the water supply of the plant is unbalanced.

Description

technical field [0001] The invention relates to the technical field of green roofs, in particular to a green roof with unit modular pitched roofs. Background technique [0002] The construction of sponge city is of great significance to reduce urban waterlogging, solve the city's own water shortage and urban heat island, and improve the ecological environment. [0003] Green roof is one of the important contents and specific measures to promote the construction of sponge city. Green roofs mainly achieve the reduction of peak runoff, runoff volume and runoff pollution through infiltration. The natural ecological significance of roof greening: In addition to effectively controlling urban flood disasters caused by storm runoff from the source, it can also alleviate the urban heat island effect, improve air quality, reduce urban noise, enhance landscape value, regulate rainwater flow and prolong roof life. Create a good urban ecological environment. Therefore, the constructio...

Problems solved by technology

[0005] In view of the fact that the existing planting roof structure has many layers, the detail nodes are complex, the construction process is complicated, there are many cases of water leakage in the later stage, and it is difficult to repair, and there are technologies that the planting soil is easy to slide along the inclined roof and the plant water supply is unbalanced. Problem, the present invention provides a green roof with unit modular pitched roof. The green roof is constructed based on unit modularization. Each unit module of the modular green roof itself has the functions of planting, filtering, storage and drainage, and waterproof and anti-seepage. After the production is completed, it can be directly transported to the general waterproof roof, and effectively overcomes the problem that the planting soil is easy to slide down the inclined roof, and the water storage capacity is greatly improved
