Brief Introduction to the Important Structures of the Air - shield Dam
1.Airbag
It is composed of multiple layers of NN66 or aramid framework materials and special - type rubber, and is manufactured using a number of authorized patents.
Airbag performance: The working pressure ranges from 0.7 - 0.8MPa. The designed safe inflation pressure is 8 kg, and the safety factor is 15 times that of a rubber dam. The outer - layer material is an EPDM polymer with excellent weather - resistance and ozone - aging resistance, and its anti - aging performance can exceed 50 years.
2.Water - retaining Shield Plate
Material: Stainless steel, carbon steel (with surface polyurea or hot - dip galvanized)
Specification: Each unit is 5m long, and high - strength rubber composite belts are used for soft connection between units.
Structure: It is made of steel plates with a thickness of over 16mm, in an arc shape, and stiffeners are welded on the water - facing side.
