An inflatable rubber dam is a flexible water-retaining structure made of high-strength
synthetic fabric reinforced
rubber. The dam bag is inflated with water (or air) to form a barrier that holds back water,
and can be deflated to
lie flat on the riverbed when flood discharge or water release is needed.

Structure

Dam bag: made of nylon or polyester fabric core coated with rubber layers, offering high
tensile strength and
excellent weather/aging resistance
Anchoring system: bolts and clamp plates secure the dam bag to the concrete foundation
Filling & draining system: includes water pump, control valves, and drainage pipes

Key Features

Simple installation, shorter construction period, and lower cost compared to traditional
concrete gates
Flexible operation � can be inflated or deflated as needed to control water level
Good flexibility and better earthquake resistance than rigid structures
Low maintenance cost and long service life (typically 15�20 years or more)
Does not obstruct flood discharge, drainage, or vessel passage when deflated

Applications

River water storage and irrigation
Urban flood control and water level regulation
Water retention for power plants and wastewater treatment facilities
Landscape water storage and ecological water replenishment
