Inflatable rubber dam Water-filled rubber dam Manufacturer direct supply

self-control, and simple operation and management. It is designed and produced in accordance with international standards, including: design safety factor of 8.5, design service life of 25-30 years, and dam bag thickness is 1.5-2 times that of water-filled rubber dam. The service life is 10 years higher than that of water-filled rubber dam, and the operation is safer. The dam foundation is narrower, the dam bag area is smaller, and the filling and drainage equipment, control system and management room occupy less space. The total project cost is more economical than that of water-filled rubber dam. Among them: the investment in the foundation slab is saved by 10%, the investment in the filling and drainage and control system is saved by 80%, and the comprehensive total investment is saved by nearly 30% compared with the water-filled rubber dam.The air tightness requirements of inflatable rubber dams are higher. The dam bag manufacturing must adopt an overall seamless process, the dam surface is smoother, and it will not deform during long-term operation.

.When the water-filled rubber dam overflows at the dam top, the bag shape is relatively stable, the water flows evenly, and the scouring to the downstream is small; due to the high compressibility of gas, when the inflatable rubber dam overflows at the dam top, a notch phenomenon appears, the water flow is concentrated, and the scouring to the downstream river channel is strong.
