Description

Rubber air bag for air shield dam

Technical Field

The utility model relates to a rubber gasbag especially relates to a gas shield is rubber gasbag for dam, and it belongs to flood control equipment technical field.

Background

In the installation process of the air shield dam, holes are usually drilled in the air bag, the air bag is fixed on the pre-buried anchor bolts through the drilled holes, and finally the upper pressing plate or the shield plate is installed and fixed through anchoring according to actual conditions. Drilling holes on the air bag easily damages the sealing structure inside the air bag, so that air leakage of the air bag is caused, and the service life of the air bag is influenced. Meanwhile, when the gas shield dam is inflated and water is retained, the bolt anchoring structure of the air bag generates drawing force at the anchoring position, so that the drilling position of the air bag is deformed, the air bag leaks air, and certain potential safety hazards exist. Therefore, there is a need for a rubber airbag for an air shield dam, which has an anchoring structure independent from the airbag body, and does not destroy the sealing performance of the airbag body when the anchoring is installed.
