I. Purpose of Hebei Five-Star Power Equipment Co., Ltd.'s Flood Control Sub-Dike

[Five-Star] Prefabricated Panel Dam Flood Control Sub-Dike is mainly used for emergency flood control and rescue on soft and hard levees such as sandy loam, loam, clay, concrete, and asphalt to prevent overtopping.

II. Main Features of the Flood Control Sub-Dike

The [Five-Star] Prefabricated Panel Dam Flood Control Sub-Dike from Hebei Five-Star Power Equipment Co., Ltd. is a new, fast, low-cost, and environmentally friendly disaster prevention and mitigation equipment that breaks through traditional thinking modes and abandons traditional dike-building materials and processes. It features water control using water, high efficiency and speed; flexible dam assembly and strong adaptability; easy storage and transportation, low cost; recyclable and reusable, green and environmentally friendly, among other characteristics.

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

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

The [Five-Star] Prefabricated 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. Crossbeam 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: The [Five-Star] exclusively developed foldable water-retaining panel uses connecting shafts to link multiple panels into a whole. When not in use, several panels can be folded together to reduce space. When in use, they can be instantly deployed to speed up assembly. The foldable water-retaining panel is made of corrugated fiberglass material or specially made color steel plate, aluminum alloy plate, and waterproof PVC plate, connected to the crossbeam as one unit 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, made of pressed round steel. Depending on the levee foundation, there are two usage methods: when used on soft levee foundations, it is placed upside down in the trench to resist displacement; when used on hard levee 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 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 angle frames, crossbeams, foldable water-retaining support panels, and other components connected and tightened to form a rigid sub-dike body. The water-retaining support panel functions as the water-retaining panel of a panel dam.
