Revegetation system on steep rocky slopes and implementing method thereof

Abstract

The invention discloses a revegetation system on steep rocky slopes and an implementing method thereof, which are suitable for surface vegetalization of steep rocky uncover slopes with the gradient of 60 degrees above. A slope drainage system is arranged in the system to prevent the vegetalization layer from being flushed by rainwater and reduce water loss and soil erosion; a mix-sprayed vegetalization layer plastic-covered with iron wire corrugated meshes and consisting of continuous fiber is arranged on the slopes and has stable structure, rich nutrition and functions of water conservation and ventilation. The casting separator prevents the mix-sprayed vegetalization layer from sliding downwards; and a drop irrigation facility is distributed to make sure that the vegetalization layer is moist. After maintenance of mix-sprayed construction on the slopes, the vegetable layer with herbaceous plants and shrubs can be effectively formed, thereby reconstructing the destructed vegetables on the slopes and recovering the natural landscapes on the uncover slopes.

Description

Technical field [0001] The invention relates to a vegetation reconstruction on a rocky slope, in particular to a system for vegetation reconstruction on a high and steep rocky slope and an implementation method of the system. Background technique [0002] In recent years, due to the acceleration of development and construction and urbanization, the contradiction between urban construction and ecological protection has increased. In the process of infrastructure construction such as transportation, water conservancy and municipal facilities, a large number of mountain flats, quarrying and taking soil have not only destroyed the topography and native vegetation, but also formed many broken mountain zones characterized by exposed rocky slopes. It forms a strong contrast with the color of the natural background mountain, and therefore affects the urban landscape, and has extremely adverse effects on soil and water conservation, ecological protection and human settlements. If it is no...

Problems solved by technology

The key to the spraying greening technology is to form a stable vegetation layer. The traditional spraying substrate is mainly composed of peat soil (organic matter) and Portland cement (curing agent), which are easy to be washed away by rainwater and uneven greening during use. , poor slope protection and drought resistance, lack of nutrients, etc.

This type of slope protection technology is similar to the thick-layer substrate spraying technology developed by Japan in the 1980s with Portland cement as a stabilizer. Due to the poor stability of the soil layer formed by spraying, insufficient nutrients and water shortage, It is difficult to meet the long-term growth requirements of plants. Once the heavy rain washes away, the soil layer will easily collapse and cause the slope protection to fail.

Although Japan's thick-layer base material spraying slope protection technology is very advanced, it is not directly applicable to domestic conditions due to the great disparity in natural conditions and high cost.
