IV. Structural Principle of the Assembled Panel Dam Flood Control Sub-dike
1. Structure and Function of the [Five-Star] Assembled Panel Dam Flood Control Sub-dike
The [Five-Star] Assembled Panel Dam Flood Control Sub-dike mainly consists of two parts:
(1) Sub-dike support angle frame: Made of aluminum alloy profiles connected by shafts, 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 of the dam body when needed. The beam connecting rod: Made of aluminum alloy square materials connected with special joints, it serves as the connecting support member of the dam body.
(2) Foldable water-retaining panel: The exclusively developed foldable water-retaining panel by [Five-Star] uses connecting shafts to join multiple panels into an integrated unit. When not in use, several panels can be folded together to save space. When deployed, it can be instantly unfolded to enhance assembly speed. The foldable water-retaining panel is made of corrugated fiberglass material or specially designed color steel plates, aluminum alloy plates, and waterproof PVC plates, which are connected to the beam as a whole using special fixing devices. Its functions: first, as a connecting piece to link adjacent angle frames, forming the load-bearing carrier of the dam body; second, as a rigid connecting plate. The bottom of the panel is equipped with positioning fixing piles, formed by pressed round steel. Depending on the dike foundation, there are two usage methods: when applied on soft dike foundations, it is inverted in the trench to resist displacement; when applied on hard dike foundations, it serves to position, retain water, prevent seepage, and compact the water-sealing elastomer.
V. Working Principle of the Assembled Panel Dam Flood Control Sub-dike from Hebei Five-Star Power Equipment Co., Ltd.
The [Five-Star] Assembled Panel Dam Flood Control Sub-dike adopts the principle of panel dams in hydraulic engineering. It forms a rigid sub-dike body by connecting and fastening multiple angle frames, beams, and foldable water-retaining support panels. The water-retaining support panel functions as the water-retaining face of the panel dam.
