Structure and Working Principle of Prefabricated Flood Control Sub-dike

I. Purpose of Hebei Five-Star Power Equipment Co., Ltd.'s Flood Control Sub-Dike
[Five-Star] The assembled panel dam flood control sub-dike is primarily used for emergency flood control and embankment reinforcement on soft and hard embankments such as sandy loam, loam, clay, concrete, and asphalt.
II. Main Features of the Flood Control Sub-Dike
Hebei Five-Star Power Equipment Co., Ltd.'s [Five-Star] assembled panel dam flood control sub-dike is a new, fast, economical, and environmentally friendly disaster prevention and mitigation device that breaks through traditional thinking modes and abandons conventional dike-building materials and techniques. It features water control using water, high efficiency and speed; flexible dam assembly and strong adaptability; easy storage and transportation with low cost; recyclable and reusable, green and environmentally friendly, among other characteristics.

IV. Structural Principle of the Assembled Panel Dam Flood Control Sub-Dike
1. Structure and Function of [Five-Star] Assembled Panel Dam Flood Control Sub-Dike
[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 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 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 rod of the dam body.
(2) Foldable water-retaining panel: [Five-Star] exclusively developed foldable water-retaining panels are connected into a whole using connecting axles between panels. When not in use, multiple panels can be folded together to reduce space. When in use, they can be instantly unfolded to increase assembly speed. The foldable water-retaining panels are made of corrugated fiberglass materials or specially made color steel plates, aluminum alloy plates, and waterproof PVC plates, which are connected to the beams as a whole through special fixing devices. Their functions: first, as connectors to link adjacent angle frames to form the load-bearing carrier of the dam body; second, as rigid connecting plates. The bottom of the panels is equipped with positioning fixing piles, formed by pressed round steel. Depending on the embankment foundation, there are two usage methods: when applied on soft embankment foundations, they are inverted in the trench to resist displacement; when applied on hard embankment foundations, they serve as positioning water-retaining anti-seepage plates and compacted water-stop elastomers.
V. Working Principle of Hebei Five-Star Power Equipment Co., Ltd.'s Assembled Panel Dam Flood Control Sub-Dike
[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, foldable water-retaining support panels, and other components. The water-retaining support panels function as the water-retaining panels in panel dams.
