Description

An environmentally friendly ecological roof for building a sponge city

technical field

The utility model relates to the fields of environmental protection and sponge city planning, in particular to an environment-friendly ecological roof for building a sponge city.

Background technique

Sponge city is a popular concept nowadays. As the name suggests, it is a city that can 'absorb water'. It can 'breathe' and 'elastic' like a sponge. When it rains, it absorbs, stores, seeps and purifies water, and stores it when needed. The existing water is “released” and utilized, thereby combining the pollution prevention and ecological restoration of the urban water circulation system, and allowing the city to form an interconnected ecosystem.

A sponge city can well adapt to changes in the environment and play a very effective role in coping with natural disasters caused by rainwater. The sponge construction of buildings and communities is one of the important contents of implementing the construction of a sponge city, and it is also an important part of the development of the entire urban construction space. When rain and floods come, the runoff from building roofs is one of the important causes of urban waterlogging. Therefore, the transformation of urban building roofs into "green roofs" can effectively relieve the pressure of urban rainwater runoff. On the one hand, collecting and storing rainwater through the sponge city structure, and using rainwater for irrigation can save various energy consumption; on the other hand, the "green roof" will form a good urban landscape and improve the overall greening rate of the city. "Green roof" is a comprehensive design that integrates green plants, runoff structures, building structures, etc., also known as planting roofs, roof greening, etc. Landscape way. Building roofs occupy about 50% of the city's impermeable surface, and most of the building roofs in China are exposed. The hard roofs and pavements make it difficult for rainwater to infiltrate, aggravating the aging of building roofs, urban waterlogging and urban heat island effect. The "green roof" structural layer is usually divided into anti-seepage layer, root layer, moisturizing layer, storage and drainage layer, filter layer, planting (soil) layer, vegetation layer, etc. from bottom to top.

The important role of "green roof":

1. Increase the urban greening area and improve the greening rate;

2. Promote urban high-altitude air purification, sound insulation and noise reduction, and open up high-altitude biological habitats;

2. Capable of collecting rainwater runoff for irrigation or water reuse in buildings;

3. The multi-layer structure of "green roof" can protect the building surface and slow down the aging of the roof;

4. Absorb building heat and alleviate the urban heat island effect;

5. Reduce building energy consumption, comprehensively utilize roof functions, and create a pleasant leisure landscape environment;

6. The combination of artificial and natural, and the use of ecological measures to reduce the risk of urban waterlogging;

7. Ecological transformation of urban development concepts and construction methods;

8. Repair the living environment and realize the beautiful vision of future livability.

In the prior art, the green area is too limited, the roof surface cannot be better covered, and the direct inflow drainage pipes flowing down from the roof cannot be effectively reused for many times.
