Embodiment 1

[0023] Example 1: Please refer to figure 1 , the present invention provides a technical solution: a green roof device for sponge city construction, comprising: a building roof 1, an anti-seepage layer 2, a sewer 10, and the top of the building roof 1 is provided with an anti-seepage layer 2 for the roof Waterproof, a sewer 10 is provided on the outside of the top of the building roof 1 to facilitate the rapid discharge of excess rainwater on the roof and prevent waterlogging on the roof. A manhole cover 3 is provided above the sewer 10 to filter large impurities and prevent blockage of the sewer 10. The top of the building roof 1 is located The top of the anti-seepage layer 2 is provided with a root-separating layer 9, which is used for the isolation of the 4 roots of the vegetation layer, and prevents the root system of the vegetation layer 4 from contacting the building roof 1 to cause damage to the roof. The top of the root-separating layer 9 is provided with a moisturizing ...

Abstract

The invention discloses a green roof device for sponge city construction, which comprises a building roof, an impermeable layer and sewers, the impermeable layer is arranged at the top of the building roof, the sewers are arranged around the outer side of the top of the building roof, a well lid is arranged above the sewers, a root separating layer is arranged at the top of the building roof above the impermeable layer, and the root separating layer is arranged above the impermeable layer. The plant layer is irrigated through spraying of a spraying pipe, rainwater and impurities accumulated in the water storage and drainage layer are few through multiple times of filtering, the stability of the amount of accumulated water in the water storage and drainage layer is guaranteed through a drainage pipe, deterioration caused by accumulation of a large amount of rainwater is prevented, and the water storage and drainage layer has the advantages of being simple in structure and convenient to use. Meanwhile, sediments in the back-flushing water tank are flushed regularly through the water pump, rainwater in the water storage and drainage layer is prevented from going bad, and the stability of irrigation water quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a green roof device for sponge city construction. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The green roof is a whole roof system composed of green plants as the main covering, together with the planting soil layer required for plant survival and the protective layer (plant root blocking layer), drainage layer, waterproof layer, etc. required for the roof. Green roof is one of the commonly used technologies in green building and sponge city construction. Green roofs do not occupy additional urban construction land, and have many advantages such as energy saving, increasing urban green space, and reducing urban h...
