In the recent years, ecological earth moulded bag technique is widely used in the projects for channel water slope protection. The products is combination of material engineering and structure engineering which can meet the engineering and ecological balance. Compared with the past revetment project which mainly formed with block stones and reinforced concrete, ecological earth moulded bag has many advantages in ecological environment, stability and construction convenience etc. Based on the mature earth moulded bag technique, it can constitute solid revetment structure and good vegetation carrying body. Benefit from its unique feature, construction period and the cost will be greatly decreased and the ecological environment can be well protected. The ecological earth moulded bag technique meets the request of engineering, ecology and landscape which has high value for promotion.
