Structural principle of the prefabricated folding plate dam flood control sub-dike
1. Structural composition and function
Main components of the prefabricated folding plate dam flood control sub-dike:
(1) Corner frame: Made of aluminum alloy profiles connected by shafts, serving as the support framework of the dam body.
(2) Crossbeam: Composed of aluminum alloy square materials connected by **joints, acting as the connecting support members of the dam body.
(3) Water-retaining panel: Made of corrugated fiberglass material, quickly linked via hinges and connected to the crossbeam as a whole through **fixing devices.
Its functions: first, as a connector to link adjacent corner frames, forming the load-bearing carrier of the dam body;
second, as a rigid connecting plate.
(4) Rubber elastomer: Made of high-quality rubber with elastic functionality, used for sealing and water retention between adjacent support panels.
(5) Positioning fixing pile: Formed by pressing round steel.
2. Working principle
The prefabricated folding plate dam flood control sub-dike applies the principle of face rockfill dams in hydraulic engineering. Multiple corner frames, crossbeams, and water-retaining panels are connected to form a rigid sub-dike body, with the water-retaining panels serving the water-blocking function of a face rockfill dam. During construction, it is embedded into the dike foundation soil to prevent seepage around the structure.
