Product Description

Water Inflatable Rubber dam with Stable Structure

Sep. 27, 2023

Water inflatable rubber dam is a kind of water-inflated stable tear-shaped rubber dam. Rubber dam consists of civil works, dam bag, anchor, filling drainage facilities and control system. It is made of strength canvas as reinforced framework and rubber layer which ensure tightness of the rubber layers. Compared with air inflatable rubber dam, water inflatable rubber dam is more expensive and slower to fill but more stable to provide optimal control over upstream water levels. It is fixed to concrete to create a permanent dam or floodgate. Water can spill over the top automatically without additional support or adjustment. When the flood is coming, rubber weir can completely collapse, does not have water resistance. It is usually used to retain water, adjust the water level, irrigation, generate hydro-electric power, control flood, etc.
