Product Description

T003 Water Conservancy Project China Good Price Air Inflatable Rubber River Water Dam /Rubber Inflatable Waterproof Dam/ Weir/ Spillway Gate Air-filled

The air-filled dam has a regulation apparatus consisting of a piping system leading from the inside of the rubber dam via a shaft system into the control room. The bottom of the shaft is below the level of the weir sill in order to be able to drain off the condensed water that has formed.

The operating room above houses the regulating and control equipment with fan. Control is via a headwater probe. The control cabinet with the electrical control and regulating equipment is also located in the operating room.

In the standard Hydro Construct design, all steel components (anchoring and clamping system) are hot-dip galvanised, the piping system and anchor bolts are made of stainless steel.

The main advantage of the air-filled system is faster recovery after a flood event.

Under normal operating conditions, the rubber dam is inflated, and can be used to regulate the water level with continuous lowering up to 15%, after which it is usually completely deflated, but can also be operated further if the irregularity of the weir discharge does not play a role.

This results in a V-shaped buckling of the membrane.

Available Sizes:  

Height can be designed with a range of 1-8 meters.
Length can be 1000 meters, even longer.
