We take pleasure to introduce ourselves as one of the renowned Manufacturer, Exporter & Supplier of Bookend Rubber Dam in Hengshui, Hebei, China. Bookend rubber dam, also named as spine type rubber dam, has obvious fins on the dam body to form a rising angle when the dam is inflated. It is made of high strength canvas as the reinforced framework and synthetic rubber fixed to a reinforced concrete foundation using clamping plates and anchor bolts. In dry seasons, the rubber dam is inflated by air or water to retain water for industrial, agricultural and living water demands; in rainy seasons, the air or water in the sealed bag can be deflated out to release floodwater from river course. Bookend rubber dam heightens overflow's water head and eliminates vacuum underneath the dam to reduce the vibration and abrasion.
