1. The pneumatic shield gate system, also known as the pneumatic shield dam, is a new type of hydraulic structure that is supported by a set of rubber airbags. The upstream water surface uses a steel water retaining shield plate, which inflates and exhausts the rubber airbags to achieve water blocking and dam collapse. 2. The main components of the gas shield dam are airbags, shield plates, safety suppression belts, anchors, pneumatic control systems, and electric control systems. The secondary components are the connecting straps and fixing screws between the spoiler and shield

Pillow type rubber dam (right plug) Pillow type rubber dam (left plug) Rubber dam is a water retaining dam that is designed according to the dimensions of length and width on the foundation slab. The rubber cloth is anchored on it to form a long, wide, and high closed body, and water (gas) is transported to the rubber bag through a pipeline pre embedded in the concrete slab through a filling and drainage system.

Slope type rubber dam collapse state rubber dam is a water retaining dam that anchors rubber cloth on the foundation slab according to the dimensions required by the length and width design, forming a long, wide, and high closed body. The water (gas) is transported to the rubber bag through the pipeline pre embedded in the concrete slab through the filling and drainage system. Working principle of rubber dam: The height of the rubber dam can be adjusted, and the dam top can overflow. Rubber dam filling with water (air)

The collapse state of the book ridge type rubber dam has a cross-sectional shape similar to the back of the book. When the dam bag is filled and overflowed, the back lifts the water flow at the top of the dam, forming a raised angle. At a certain depth of flowing water, a sealing body cannot be formed under the dam, thereby reducing the vibration of the dam bag and reducing the wear and tear of the dam bag. The overall appearance of the dam body is flat and smooth, and it is formed in one go.
