This invention belongs to the field of floating bridge opening and closing technology, and discloses an automatically opening and closing floating bridge device, including two sets of symmetrically arranged floating bridge structures and opening / closing section structures, as well as two pontoon structures. One end of each opening / closing section structure is rotatably connected to the floating bridge structure, and the other end is connected to a pontoon structure. The pontoon structure includes a pontoon body, a propulsion device, a traction mechanism, a T-shaped connector, a conical connector, and a floating pile holder. The propulsion device consists of a spray pump, a universal joint, and a spray pump motor, with the spray pump and motor connected via the universal joint. The propulsion device is installed on one side of the bottom of the pontoon body. The traction mechanism consists of an electric winch, a pulley assembly, and a wire rope, with the wire rope connecting the electric winch and the pulley assembly. The traction mechanism is located on the upper part of the pontoon body, away from the propulsion device. This invention has a simple opening and closing principle; the opening and closing of the floating bridge is completed with a single button press, requiring no other equipment intervention, saving time and effort.

The application discloses a variable tension leg type special-shaped pontoon bridge foundation, and relates to the technical field of floating foundation structures. The foundation comprises a pontoon main body, a plurality of tension leg systems and a plurality of tension legs. The pontoon main body is used for being connected with the bottom of a bridge pier and providing buoyancy. A plurality of variable hydraulic rod systems are circumferentially and intervalled arranged on the outer side of the pontoon main body. Each variable hydraulic rod system can be adaptively stretched and contracted when the pontoon main body is horizontally or vertically displaced. One end of each tension leg is connected with one variable hydraulic rod system, and the other end is used for being connected with a seabed foundation. The pontoon main body is arranged at the bottom of the bridge pier, thereby providing a floating foundation for the bridge pier. When the pontoon main body is horizontally or vertically displaced, the plurality of variable hydraulic rod systems are adaptively stretched and contracted, thereby cooperating with the tension legs connected with the seabed foundation, so that the wind and wave load resistance performance of the overall structure is improved, and the pitching and rolling of the bridge are reduced.

This invention discloses a novel honeycomb-patterned, multifunctional wave-damping and wind-resistance-reducing floating structure, relating to the field of floating facility technology. The invention comprises multiple arrayed floating units, each unit consisting of coaxial upper and lower structures. The upper structure has a larger perimeter, and a flow channel is formed between adjacent lower structures. The upper structure is an octagon with an arc, while the lower structures are either cylindrical at the top and conical at the bottom. The units are connected by connecting lugs to form a honeycomb-patterned, hollow mesh structure, with wave-dissipating channels formed between the lower structures of adjacent floating units. This invention achieves wave dissipation, wind resistance reduction, and reduced structural sway. It is easy to construct, allows for easy passage of debris, and is suitable for various water-related engineering projects such as floating bridges, docks, floating parks, water landscape projects, and floating platforms.
