[0002] Air shield dam is a kind of low head water retaining structure commonly used in my country. The main components of air shield dam are water retaining shield plate, air bag and inflation and exhaust control system. By filling air into the air bag, the air bag swells and pushes the shield plate to rise to play the role of water retaining. By exhausting the air in the air bag, the air bag returns to a flat state under the weight of the shield plate and the gravity of water, and the shield plate collapses to the dam foundation to achieve the role of flow.

[0003] However, at the side walls of the gas shield dam, there is a gap between the shield plate and the side walls, which often causes leakage. Figure 1 The L-shaped side stop seal shown fills the gap, but due to the insufficient flatness of the side wall, the side stop seal cannot completely stop water, and after multiple dam raising and dam collapse, the friction between the side stop seal and the side wall causes the side stop seal to wear, so that the side stop seal cannot completely fill the gap between the shield plate and the side wall, resulting in leakage.
