What is the Spillway Gate?

 Spillway gates synthesize both advantages of rubber dam and steel gate dam which is a new type of hydraulic structure.

Due to spillway gates not restricted by geographical climate conditions, environmental applicability strong. Can be used in city flood control, environment beautify,irrigation,hydropower, tourist attraction, sewage control, aquaculture. Especially play big role in flash flood ,flotage ,rolling stone, sediment river

And also used to

●Steel gate in adaptation environment.

Like: broad river, river coating depth, flash flood, navigation river

●Hydraulic automatic flap gate in adaptation environment.

Like: rapid flow,flotage,sediment,rolling stones river.

●Rubber dam inadaptation environment. 

Like:large,rapid,flotage,rolling stone, ice run river

●Exceed rubber dam, hydraulic automatic flap gate design scope and bear ability environment.

Like: dam height over 5m,top running water over 1m project

2.     Operating principle :

A Block water

Through inflating the air bladder to support the steel gate to block water.

B  Spillover

When spillover, the air bladder under the steel panel can be protected from water scouring and flotage attacking.

C  Dam height adjust

Adjust the air pressure to get the required height

D  Deflation

When air bladder deflated, gate panel and air bladder are both cling to the riverbed and the air bladder was entirely covered by the steel panel. (All of the operation processes can be under automation supervisory system)
