Recently, the China Water Conservancy published a news report on the Xianyang Gas Shield Dam project in Shanxi, which was built by Yantai Sunny Rubber Co., Ltd. of Tongcin Group.

Xianyang 4m high gas shield dam over water landscape project undertaken by Sunny Rubber

The water ecological management project of the Xianyang City section of the Weihe River is located in the main stream of the Weihe River in Xianyang City, Shanxi Province. The main task of the project is to use the main river channel dam and water storage + the riverside ecological park on both sides to ensure the flood control safety. Comprehensive improvement to improve urban water ecological environment. The project uses a domestic 5-hole gas shield dam produced by Yantai Sunny Rubber Co., Ltd. The single-hole dam has a flow width of 90 meters and a total width of 450 meters. The dam is 3 meters high and the dam roof is 461.6 meters long. The gas shield dam is the first application on the main stream of the Weihe River. Since the water storage operation in September 2017, the project safety and water ecological landscape have achieved good results, and accumulated experience for the design of large span, large flow and multi-sand gas shield dam.

The gas shield dam is a new type of gas shield landscape steel dam. Compared with the rubber dam, it has the advantages of small airbag volume and short charging and exhausting time, which can realize timely and rapid dam, thus solving the flooding of the cement sand well. The contradiction between the main river channel and the impoundment. According to the water regime forecast, the gas shield dam can quickly discharge the dam venting water storage area before the arrival of the upstream flooding cement sand, and ensure the safe discharge of the flooded cement sand. After the flood, the dam can be quickly dammed to form a landscape waterfall. Beautiful, in harmony with the city environment. At the same time, because the gas shield dam can quickly collapse the dam in a short time, its ability to carry sand in the process of rapid dam collapse is greatly enhanced, and the sand carrying capacity of the dam can be fully utilized to carry out the hydraulic discharge of sediment in the water storage area. Effectively solve the problem of sedimentation in the water storage area. 

In addition, the air shield dam supports the airbag hidden behind the shield. When the flood dam is being smashed, the muddy sediment and floating objects in the water pass over the shield, supporting the airbag and the auxiliary system to be free from water flow and hooking. The airbag is not easily broken and has a long service life. The gas shield dam control system is simple, and the air compressor is used for the charge and exhaust control. The air pressure control station is small in scale, has the low cost characteristics of the collapsed dam, and has low operation and management cost.

China began to introduce foreign gas shield dams many years ago, and the promotion was slow in view of the high price. In recent years, Yantai Sunny Rubber Co., Ltd. has successfully attacked the gas shield dam technology through efforts, which enabled the gas shield dam to be successfully localized.

As a new technology promotion dam type of the Ministry of Water Resources, it has been effectively promoted and applied. The Shanxi Xianyang gas shield dam project reported by the China Water Conservancy Report was first adopted by the gas shield dam product on the main stream of the Weihe River. It is also the first domestically produced gas shield dam with the largest design and success in the multi-sand river.
