The working principle of flood control sub-dikes

[Five-Star] Assembled Panel Dam Flood Emergency Sub-dyke is mainly used for emergency flood overtopping control on soft and hard levees such as sandy loam, loam, clay, concrete, and asphalt.
II. Main Features of the Flood Emergency Sub-dyke
The [Five-Star] Assembled Panel Dam Flood Emergency Sub-dyke from Hebei Five-Star Power Equipment Co., Ltd. is a new, fast, low-cost, and environmentally friendly disaster prevention and mitigation device that breaks through traditional thinking modes and abandons traditional dyke-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 Assembled Panel Dam Flood Emergency Sub-dyke
1. Structure and Function of the [Five-Star] Assembled Panel Dam Flood Emergency Sub-dyke
The [Five-Star] Assembled Panel Dam Flood Emergency Sub-dyke mainly consists of two parts:
(1) Sub-dyke 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 by [Five-Star] uses connecting shafts to link panels into an integrated whole. When not in use, multiple panels can be folded together to save space. When in use, they can be instantly unfolded to enhance assembly speed. The foldable water-retaining panel is made of corrugated fiberglass material or specially colored steel plates, aluminum alloy plates, and waterproof PVC plates, which are connected to the beam as one unit through 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 levee foundation, there are two usage methods: when applied on soft levee foundations, it is inverted in the trench to resist displacement; when applied on hard levee foundations, it serves to position, retain water, prevent seepage, and compact the water-stop elastomer.
V. Working Principle of the Assembled Panel Dam Flood Emergency Sub-dyke from Hebei Five-Star Power Equipment Co., Ltd.
The [Five-Star] Assembled Panel Dam Flood Emergency Sub-dyke adopts the principle of panel dams in hydraulic engineering, using multiple angle frames, beams, foldable water-retaining support panels, and other components connected and fastened to form a rigid sub-dyke body. The water-retaining support panel functions as the water-retaining panel in a panel dam.
