Channel revetment is affected by external factors such as temperature, runoff, tide, and ship waves for a long time, and soil loss and structural collapse are prone to threaten the safety of the channel itself and land buildings. In the past, the channel protection projects used purely reinforced concrete, mortar, and masonry structures, ignoring ecological nature. With the development of society and economy and the progress of civilization, people are aware of the adverse effects of such hard bank protection on the environment, which can easily cause ecological degradation. It is imminent to establish a bank revetment application system technology that not only satisfies the stability of the channel embankment but also helps maintain the ecological balance.
Ecological geotechnical bag technology is a technical product that is widely used in waterway slope protection projects at home and abroad in recent years. It integrates engineering and ecological environmental protection and is a product of the combination of two disciplines: material engineering and structural engineering. In the 1980s, it was proposed and successfully constructed by Japan's Asahi Kasei Industrial Co., Ltd. In recent years, Australia's Foreshore has gradually entered the country through efforts and has been widely used in Beijing Lugou Bridge Project. Compared with the previous reinforced concrete and mortar-filled and reinforced concrete block revetment structures, it has many advantages such as ecology, stability, and convenience. based on the current mature geotechnical bag technology, it can not only form a solid revetment structure, but also become a good vegetation carrier. It achieves the three functions of fast construction, cost economy, and ecological continuity, which meets the requirements of engineering, ecology, and landscape, and has high promotion value.
