Abstract
The invention discloses an integrated trilateral buoyancy tank foundation for a marine anemometer tower. Three buoyancy tanks are connected end to end and welded to form an integrated structure with a regularly triangular foundation plane; water injecting valves are arranged on the buoyancy tanks; reinforcement rib plates are arranged in the buoyancy tanks for reinforcing the rigidity of the buoyancy tanks; square holes are formed in the bottoms of the reinforcement rib plates; skid resisting skirt plate boxes with bottom openings are arranged in the intersections of the three buoyancy tanks; and after the buoyancy tank foundation is floated to a preset construction position for sinking, the buoyancy tank foundation is inserted in a seabed to stop horizontal slippage. The integrated trilateral buoyancy tank foundation has the following beneficial effects: the whole trilateral buoyancy tank foundation is better in structural stability, saves steel materials, has good stress performance, and is convenient for marine floating installation; the buoyancy tanks can provide the buoyancy for the towing of the whole structure of the anemometer tower to prevent the use of large transport ships; and small tugboats are only required to arrive at a destination for sinking and mounting, so that the engineering cost is reduced, and the building time of the anemometer tower structure is largely shortened.
Description
Technical field
The present invention relates to ocean, water conservancy and wind power foundation technical field of structures, particularly relate to a kind of monolithic triangle buoyancy tank for offshore anemometer tower basis.
Background technology
Wind-powered electricity generation is a kind of reproducible clean energy resource, in recent years, along with the whole world developing rapidly the common concern of wind energy resources and wind power industry, national governments, enterprise or Wind Power Generation business start investment and build wind energy turbine set, an important process of offshore wind farms early development is acquisition and the assessment of wind-resources, its the most frequently used means set up anemometer tower exactly, and for future, the investment construction of wind energy turbine set obtains first-hand wind energy data.
During at sea anemometer tower structure is built, proportion occupied by foundation investment comparatively large (about 70%), anemometer tower is a kind of tall and slender structure building, its military service phase is generally 3-5, tradition anemometer tower foundation form mostly is pile foundation or gravity type foundation, offshore construction and mounting cost is higher and recovery utilization rate is low, develops and is a kind ofly adapted to offshore anemometer tower and small investment, quick construction, the foundation structure that can reuse have significant economic benefit.
Summary of the invention
The object of the invention is for above-mentioned existing problems, a kind of monolithic triangle buoyancy tank for offshore anemometer tower basis is provided, this buoyancy tank basis symmetry is better, structure is comparatively stable, stress performance good and be convenient to install, can towage transportation by driving be carried out, can effectively reduce cost of transportation and difficulty of construction, and in construction, reduce the use of large ship, effectively shorten short construction period, reduce marine wind electric field construction cost.
Technical scheme of the present invention:
A kind of basis of the monolithic triangle buoyancy tank for offshore anemometer tower, end to end and be welded into the overall structure that basic plane is equilateral triangle by three buoyancy tanks, buoyancy tank is provided with Water filling valve, deep floor is provided with to strengthen the rigidity of buoyancy tank in buoyancy tank, square hole is provided with bottom deep floor, arrange the anti-skid skirtboard case of bottom opening three buoyancy tank intersections, buoyancy tank basis transportation by driving inserts sea bed to stop the slippage of buoyancy tank foundation level after predetermined construction location sinks.
Described buoyancy tank is made up of Plate Welding, and step surface minor face is 9.1m, long limit is 12.5m, width 2.5m, highly 2.2m, steel plate wall thickness 25mm; Buoyancy tank inside is evenly equipped with the thick transversely stiffened plate of 18-25mm along its length, and be provided with the square hole of width 20cm, height 10cm bottom deep floor, deep floor spacing is 1.5m.
Described anti-skid skirtboard case is welded by five blocks of 25mm steel plates and is surrounded by the bottomless tetrahedron of lid, length of side 1.2m, hem width 1.0m, height 0.8m.
Implementation method of the present invention:
Triangle buoyancy tank basis is welded assembled shaping on the coast, or with top anemometer tower transition section structure integral solder, carry out single step towage installation by barge.After overall triangle buoyancy tank basis transportation by driving towage to predetermined construction location, sink down into design elevation by valve reserved on casing to water filling in buoyancy tank.The buoyancy tank that can simultaneously surround skirtboard in sinking watching take to take out the mode of negative pressure auxiliary sink, skirtboard inserts sea bed immobilizing foundation simultaneously, prevent buoyancy tank foundation level to slippage.
The invention has the beneficial effects as follows:
This overall triangle buoyancy tank foundation structure stability better and save steel, stress performance good and be convenient to marine transportation by driving install, this buoyancy tank provides buoyancy when can be the towage of anemometer tower overall structure, avoid using bulk transport boats and ships, only skiff need be adopted to arrive at the destination and carry out sinking and installation, reduce engineering cost, greatly shorten the construction time of anemometer tower structure.
