Description

Technical Field

[0001] The invention relates to the technical field of river channel repair equipment, and in particular to a combined ecological floating bed for river channel repair and a use method thereof. Background Art

[0002] The combined ecological floating bed is an innovative river restoration technology. It integrates a variety of ecological floating bed units to form an efficient water purification system. These floating beds are usually composed of floats, net bags and a variety of aquatic plants. They can float on the water surface and make full use of the water space. Through the absorption of plants and the decomposition of microorganisms, the combined ecological floating bed can effectively remove nutrients and harmful substances such as nitrogen and phosphorus in the water, purify the water quality and prevent eutrophication of the water.

[0003] Chinese utility model patent CN208532392U discloses a modular ecological floating bed for urban river restoration, including slots, screws, buoyancy holes, a main board, a bottom plate, an anti-skid plate, side slots, a card plate, a through hole, a splicing device, and a knob. The buoyancy holes and the main board are an integrated structure, the upper surface of the bottom plate is fitted with the lower surface of the main board, the side slots and the main board are an integrated structure, the seesaw is pushed by a push plate, and the other seesaw is driven by the seesaw to squeeze the installation head upward for fixed installation. The splicing device makes installation convenient, improves work speed, and saves time.

[0004] Before installing the combined ecological floating bed, usually before placing the flower pots for planting aquatic plants, adjacent floating beds are manually tied and fixed with cable ties to ensure stability, but this significantly prolongs the installation time, and the quick-install structure using screws and other connectors is susceptible to water corrosion, which may damage the overall stability and service life of the floating bed; in addition, after long-term use, algae, dirt and sediment will gradually accumulate on the bottom of the float, which will not only thicken the bottom layer, but also the algae will consume a large amount of dissolved oxygen during the growth process, causing hypoxia in the roots of aquatic plants, affecting their normal respiration and physiological functions, and thus adversely affecting the overall growth conditions.

[0005] In view of this, the combined ecological floating bed and its use for river restoration need further research to save the time of overall combined installation, extend the service life, and ensure the growth of aquatic plants. Summary of the invention
