Reliable Anchoring System
HUAHAI rubber dam can be fixed to the concrete foundation using either a single or double line of anchors, forming a sealed rubber dam body. Inflated with water or air, the rubber dam can be operated to increase water level or discharge flood. The anchoring system should ensure 100% air and water tight and increase the stability of the rubber body and reduce the possibility of vibration. There are many kinds of anchoring structures for rubber dam, the most commonly used are bolt anchorage and wedge anchorage. The anchoring system of HUAHAI rubber dam will design to best suit clients’ needs.
