Water filling rubber dam is relatively stable with less vibrations and less erosion.

 Water  Filling Rubber Dam

1.Product Introduction

      Rubber dam is long tubular-shaped fabrics placed across channels, streams and weir crest to raise the upstream water level when inflated. The membrane is a multi-layer fabric made of synthetic fibre which may be rubberized on one or both sides, and possibly coated with plastic film. The fabric is quite flexible and yet exhibits very large resistance characteristics.  In open channels, they are used to divert water for irrigation, for raising existing dams, for flood control ling. Other applications include remedy measure to prevent dam overtopping and control of chemical spills in streams. 

2.Features 

Low project cost (usually reducing investment 30%-70%)Easy transportation and installation, convenient construction, shorter construction periodDam span is flexiblePier in the middle is less, easy - to -floodExcellent anti-seismic and anti-crack performance Stable regulating and controlling water level, easy to operate,  running in safetyFast in water filling and drainageWell self-excretion on deposition from upstream and downstream
