Our country's rivers are vertical and horizontal, lakes are densely distributed, the coastline is long, and the work of slope protection is very heavy. In order to prevent and control soil erosion, protect and rationally utilize water and soil resources, reduce water, drought and sandstorm disasters, improve ecological environment and ensure sustainable economic and social development, slope protection construction has always been a topic of concern and research. Many people of insight have made unremitting efforts to find new slope protection technologies with good wind resistance, small (thin) quantities, good wave dissipation, convenient construction and low maintenance and management costs. As a professional slope protection engineering company, the development and application of mold bag slope protection technology has become an important role. The development, design and construction technology of underwater bag slope protection technology have become a key project in our research field. Mold bag concrete underwater slope protection company supplies high-strength woven pattern bag cloth woven with high-strength and low elongation polypropylene, polyamide and polyester composite filament as raw materials. It has high tensile strength, wear resistance, good bursting resistance and chemical corrosion resistance. The high strength woven concrete mold bag is filled with flowing concrete in the double-layer mold bag. It is actually a kind of soft concrete formwork. It has high strength and good overall performance. It can be made into various geometric shapes with different area and thickness according to the engineering requirements. It has good flexibility when pouring. It can ensure that the molding thickness is close to the ground. It is suitable for the complex terrain of bag concrete underwater slope protection company. It can be constructed underwater without cofferdam, and the slope protection has good integrity. Compared with mortar masonry slope protection, it has the advantages of high construction mechanization, high speed, short construction period, low maintenance cost, and is not easy to be damaged by animals. Especially for the areas lack of flood control materials such as stone, it has better economic and social benefits. Geotextile bag is a kind of new building material, which can be used as concrete formwork. The surface layer of the bag cloth can protect the concrete or mortar block. It can be directly applied to underwater construction, and can replace the traditional masonry revetment, slope protection and bottom protection for thousands of years. Geotextile bags are widely used in water conservancy, transportation, construction, energy, military and other fields, such as slope protection, flood control, emergency rescue, canals, waste treatment, port construction, slope protection of rivers, rivers, seas and lakes, erosion prevention and scouring of reservoirs and dams, greening and reinforcement of hillsides. Anti seepage engineering of coastal line revetment and slope protection.
