The word "vegetation concrete" was searched by China HowNet data, and the concept was first put forward by Hu Dexi (Beijing Urban Construction Engineering Research Institute in 1997). The history of human planting flowers and grass dates back thousands of years, and the appearance of artificial building material concrete has been nearly 2 years since the advent of Portland cement. In the long years, flowers and concrete are both widely used and ubiquitous because they are closely related to human beings. However, flowers and concrete, which are inseparable from human interests, have been in contradiction and opposition for a long time because of their respective characteristics: flowers and plants cannot survive on concrete, and wherever concrete goes, flowers and plants will die out. "You can't have your cake and eat it." It seems that human beings have become accustomed to this helpless state that flowers and concrete are difficult to survive.
In p>1998, the journal Environment reported that vegetation concrete is a kind of concrete that can grow flowers and grass on its surface. The concrete has a certain strength, and its surface can reproduce flowers and plants. It is formed by organically combining the vegetation as the main body with the quilt cover, quilt bed, bed wadding and bed foundation of its carrier.
In 22, the Chinese core journal of Water Resources and Hydropower Technology, Xu Wennian and Liu Gaopeng (Three Gorges University, 22), CBS vegetation concrete slope protection and greening technology is a patented technology of Three Gorges University, which is a new technology for protecting and greening rock slopes by using specific concrete formula and seed formula. The concrete method is as follows: firstly, lay iron wire or plastic net on the rock mass, and fix it with anchor nails and anchor rods. After mixing, the raw materials of vegetation concrete are sprayed on the rock slope by conventional anchor spraying equipment to form vegetation concrete with a thickness of nearly 1cm; After spraying, cover a layer of non-woven fabric for sun protection and moisture conservation, and cement makes the vegetation concrete form a protective layer with certain strength; After a period of watering and maintenance, the grass will cover the slope and remove the non-woven fabric, and the dense grass will grow naturally. Through the application in the protection and greening project of Wangjiachong high and steep rock slope on the right bank of Gaobazhou water control project in Qingjiang River, it is proved that the greening effect is remarkable.
