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. 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 uses connecting shafts to link multiple panels into an integrated unit. When not in use, several panels can be folded together to save space. When deployed, they can be instantly unfolded to enhance assembly speed. The foldable water-retaining panel is made of corrugated fiberglass material or specially treated color steel plates, aluminum alloy plates, and waterproof PVC plates, which are connected to the beam as a whole through special fixing devices. Its functions: first, as a connecting piece to link adjacent angle frames to form 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 from round steel. Depending on the embankment foundation, there are two usage methods: when applied to soft embankment foundations, it is inverted in the trench to resist displacement; when applied to hard embankment foundations, it serves to position, retain water, prevent seepage, and compact the water-sealing elastomer.
V. Working Principle of Hebei Five-Star Power Equipment Co., Ltd.'s Assembled Panel Dam Flood Control Sub-Dike
The [Five-Star] Assembled Panel Dam Flood Control Sub-Dike adopts the principle of panel dams in hydraulic engineering. It connects and fastens multiple components such as angle frames, beams, and foldable water-retaining support panels to form a rigid sub-dike body. The water-retaining support panel functions as the water-retaining panel in a panel dam.
