Product Description

Pneumatically operated spillway gate /air bladder support gate
The pneumatically operated spillway gate is a new type hydraulic structure, which can simultaneously satisfy the safety of retaining water and stepless adjustment of discharging water level. 

Operation principle 
1. Retaining water: inflated the air bladder, it will support the gate panel stand up, and realize retaining water.
2. Overflow: when the water level higher than the gate panel, the water flow and floater will pass on the gate panel. The air bladder will not destroy because of the gate panel protection. 
3. Adjust the dam height: through adjust the inflated air pressure, to achieve the purpose of adjust the support angle of the gate panel, and finally control the water level.
4. Collapse: deflate the compressed air in the air bladder, the gate will collapse. The gate panel and air bag will next to the riverbed, the support system is more safer under the gate panel cover. 

Features:

Construction
 

Gate Panel

7. remote monitoring could realize the unmanned control.   
8. manual and automatic dual control.

Projects

Project Name:Landscape Engineering of Shidu Steel rubber gate, Juma River, Fangshan
Address:Fangshan, Beijing
Specification: 2 span, 2.1m in height, 60m in length
Project Description: This project is a reconstruction project, and the original rubber dam was destroyed in Fangshan "7.21 flood disaster". In the continues use of rubber dam and other dam types cannot meet the landscape and flood safety conditions at the same time, after repeated demonstration by experts of the Academy of Water Sciences, the final suggestion of using the Steel rubber gate was accepted and produced & installed by Yantai Sunny Rubber Co., Ltd


Project Name: Xianyang Lake Phase Il Steel rubber gate Landscape Project
Address: Xianyang, Shaanxi
Specification: 4 span ,4M in height,300M in length
Project Description:The Steel rubber gate project of Xianyang lake is an important part of the comprehensive regulation project of Weihe River in Shaanxi Province, and it is a landmark project of landscape engineering construction in sediment rich watershed in China. After the completion of the project, a new large-scale landscape lake will be built in Xianyang, covering an area of 7 million square meters than the West Lake of Hangzhou. It will become a large urban artificial lake in northern China, laying a solid foundation for the grand goal of Weihe river,Guanzhong, "the largest ecological park and the most beautiful landscape corridor" proposed by the Shaanxi provincial Party committee and the provincial government.


Project Name: Flood Control and Urban Landscape Improvement of Yangling Steel rubber gate in Shaanxi Province
Address: Yang Ling, Shaanxi
Specification: 5 span,3.5M in height,450M in length
Project Description: The project is located in the south side of Yangling Agricultural Demonstration Area in Shaanxi Province, the main stream of the midstream of Weihe River and the upstream of Zhushui River into the Weihe River.The terrain is flat and is located in the floodplain and first terrace. The geological structure is complex and the surface water is large. The construction of the main body needs to be completed before the flood season, so the safety risk is high. This is another large Steel rubber gate built by sunny rubber Co., Ltd on Weihe River after Xianyang Lake phase Il project in June 2016.

Project Name: Jinggangshan Steel rubber gate
Project Address: Jinggangshan, Jiangxi
Specification: 1 span ,2.5M in height, 55M in length
Project Description: The project was a World Bank loan project for the comprehensive management of the Dragon River in Jinggangshan. The original design was to use a water-filled rubber dam, but it was finally changed to the Steel Rubber Gate at the last minute. The project was completed before the flood season in June 2015, greatly improving the urban landscape effect of Longshi and Zhumao Meeting Square.
