Description

Ecological vegetation net

Technical Field

The utility model relates to a municipal afforestation engineering construction field especially relates to an ecological vegetation net.

Background

The ecological slope protection technology has a long history so far, and the method of laying turf and planting trees is adopted in 1633 years for treating the barren slopes in Japan, and then the technology is introduced for the first time in Central Europe in 30 years of the 20 th century, so that the ecological slope protection technology begins to be widely and rapidly developed. The earliest time in China is 1591, willows are planted on the river side to stabilize river bank side slopes in China, yellow rivers in the 17 th century flood, China pays attention to the effect of ecological slope protection technology on the river bank side slopes, although the willows start late, the willows are thick and thin, foreign technical knowledge and cases are absorbed in recent years, and the ecological slope protection technology of China is formed.

Ecological bank protection is the indispensable part in the middle of the road bank protection engineering now, and ecological bank protection technique is also more and more welcomed at modern, and this not only can make good ecological environment, also can bring certain ecological benefits for people.

Traditional bank protection technique generally only adopts simple engineering measure to carry out the stability to the side slope, mainly be cast in situ concrete bank protection, grout and step or dry masonry bank protection, precast concrete block bank protection, although these engineering facilities have played the effect to the stable in structure of side slope, but not produce positive influence to ecological environment, and the most of adoption is the compound ecological bank protection type that plant and engineering technique combined in the middle of the slope protection engineering of present majority road, not only can stable structure, and can also utilize the advantage of plant to reach the ecology function.

Ecological bank protection improves on the basis of traditional bank protection, also attaches importance to the ecological effect that artifical material and bank protection technique can reach when pursuing novel environmental protection material, is the technique that is different from the implementation green theory of traditional bank protection technique, and in the present era of explaining sustainable development, ecological problem receives more and more attention, and it is current urgent need to develop ecological technology.

The slope ecological restoration is the key content in the ecological environment construction process, the attention degree of people to the ecological environment restoration is higher and higher in recent years, and various slope ecological restoration methods are developed, so that the slope can be well protected, the engineering environment can be improved, and the beauty of the natural environment is embodied. The traditional slope protection mainly adopts engineering protection means such as anchoring, retaining and the like, and the methods can protect the potential safety hazard problem of the slope, but the environment improvement can not be really realized, and the vegetation coverage condition of the slope is still not optimistic. In contrast, our country starts to strengthen the research on plant protection methods in the slope protection technology, and establishes a slope protection system different from the traditional slope protection engineering. For example, artificial grass planting slope protection, grass laying slope protection, hydraulic spray seeding grass planting slope protection, spray mixed plant planting slope protection and the like are all common methods in the current slope greening engineering, and the slope ecological protection method brings certain help to the management of the slope environmental problems in China and also achieves effects, but a plurality of new problems appear in the slope greening process.
