Do you know what the air - shield dams we see in daily life are composed of? Today, I'll give you a detailed popular - science introduction. Those who are not familiar with it can follow me and have a look!
Composition of Air - shield Dam
An air - shield dam is composed of the dam body (rubber airbag + steel shield), anchorages, a pneumatic system, an automatic control system, and pipelines.
1. Dam Body
The rubber airbag is made up of multiple layers of skeletal fiber materials and rubber materials. The fiber materials can be polyester, nylon, aramid, or steel wire. The rubber material is divided into three layers: the outer layer is ethylene - propylene - diene monomer (EPDM) rubber with excellent weather resistance, the middle layer is a blend of neoprene with good adhesiveness and natural rubber, and the inner layer is modified butyl rubber with excellent airtightness. The steel shield can be made of carbon steel, 304 stainless steel, or 316L stainless steel according to application requirements. The pressure - resistant design of the airbag should be more than 8 times the operating pressure. The service life of the airbag should exceed 50 years.
2. Anchorages
Anchorages include embedded bolts and positioning metal structural components, as well as fastening bolts and positioning metal structural components. The materials can be carbon steel (which must be treated with zinc + coating for anti - corrosion), 304 stainless steel, or 316L stainless steel. Their size specifications and shapes should meet the requirements of the project and design.

3.Pneumatic System
A screw - type air compressor with good performance should be adopted, and its specifications should meet the requirements of the project and design. It is recommended to have one in use and one as a backup.
4.Automatic Control System and Pipelines
The automatic control system should include: PLC, lightning protection equipment, SKADA, and/or radar hydrological monitoring. The material, size specifications, and shape of the pipelines should meet the requirements of the project and design.
