IV. Structural Principle of the Prefabricated Panel Dam Flood Control Sub-Dike

1. [Five-Star] Prefabricated Panel Dam Flood Control Sub-Dike Structure and Function

The [Five-Star] prefabricated panel dam flood control sub-dike mainly consists of two parts:

(1) Sub-dike support frame: Made of aluminum alloy profiles connected by axles, it is directly installed behind the water-retaining panel using a rotating shaft. It can be folded together with the panel when not in use and quickly deployed as the support framework for the dam body. The beam connecting rod, made of aluminum alloy square materials and special connectors, serves as the connecting support member for the dam body.

(2) Foldable water-retaining panel: [Five-Star] exclusively developed foldable water-retaining panels are interconnected by axles to form an integrated unit. When not in use, multiple panels can be folded together to save space. They can be quickly deployed during use to enhance assembly speed. The foldable water-retaining panels are made of corrugated fiberglass materials or specially treated color steel plates, aluminum alloy plates, and waterproof PVC plates, connected to the beams via specialized fixing devices. Their functions: first, as connectors to link adjacent frames, forming the load-bearing structure of the dam; second, as rigid connecting plates. The bottom of the panels is equipped with positioning fixing piles, formed from round steel. Depending on the embankment base, there are two usage methods: when used on soft embankments, they are inverted in trenches to resist displacement; on hard embankments, they serve as positioning water-retaining and anti-seepage plates, compacting and sealing the water-stop elastomer.

V. Working Principle of Hebei Five-Star Power Equipment Co., Ltd.'s Prefabricated Panel Dam Flood Control Sub-Dike

The [Five-Star] prefabricated panel dam flood control sub-dike applies the principle of panel dams in hydraulic engineering. It uses multiple frames, beams, and foldable water-retaining support panels connected and fastened to form a rigid sub-dike body, where the water-retaining support panels function like the water-retaining panels in a panel dam.
