Problems solved by technology
Compared with other foundations, the composite tube foundation has low cost of basic materials and high rigidity. Its one-step installation technology can shorten the construction period. The large-scale gantry crane is hoisted into the water, and then floated and transported to the designated place by a special ship for installation. The purchase of large-scale gantry cranes is expensive, and the composite cylinder foundation is large (30 to 50 meters in diameter), and the wharf area needs to be large, which increases the composite cylinder foundation. cost

Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] Such as Figure 1-7 As shown, an offshore wind power composite cylinder foundation construction structure of the present invention includes a steel cylinder, a concrete bottom plate 2 is arranged on the top of the steel cylinder, and a transition section 1 is arranged on the concrete bottom plate 2 . The steel cylinder includes a vertical steel plate 4 and a horizontal steel plate 3 arranged on the top of the vertical steel plate 4. The inside of the steel cylinder is separated by the vertical steel plate 4 to form a honeycomb multi-compartment structure. In the honeycomb multi-compartment structure inside the steel cylinder Place pontoon 8. Vertical steel plate 4 bottoms are perforated, and temporary support beam 7 is arranged in the hole of vertical steel plate 4 bottoms, is fixed by latch 9, and buoyant box 8 is shelved on the tempor...

The invention relates to an offshore wind power composite cylinder foundation construction structure and an offshore wind power composite cylinder foundation construction method. The offshore wind power composite cylinder foundation construction structure comprises a steel cylinder and a transition section, wherein the steel cylinder comprises a vertical steel plate and a horizontal steel plate arranged at the top of the vertical steel plate, the interior of the steel cylinder is partitioned by the vertical steel plate into a cellular multi-bin structure, a hole is formed in the bottom of thevertical steel plate, a temporary support beam is arranged in the hole in the bottom of the vertical steel plate, and is fixed through a plug pin, floating boxes are arranged in internal bins of the steel cylinder, and the steel cylinder and the floating boxes are anchored in a dock through anchor chains and anchor blocks. According to the offshore wind power composite cylinder foundation construction structure, the steel cylinder is manufactured on a wharf, and after manufacture of a composite cylinder foundation is completed, the composite cylinder foundation is fixed on an installation vessel, the anchor chains and the anchor blocks are dismantled, and the floating boxes are filled with water and sink, and then are fetched out from the steel cylinder. The composite cylinder foundation is manufactured in sea, and therefore manufacture space can be saved, a large-tonnage portal crane for hoisting the composite cylinder foundation is saved, manufacture cost is substantially reduced, economic efficiency is good, and popularization and utilization are facilitated.
Description
technical field [0001] The invention relates to an offshore wind power equipment, in particular to a construction structure and a construction method of an offshore wind power composite barrel foundation. Background technique [0002] At present, the fixed foundation types of offshore wind power mainly include single pile foundation, high pile cap foundation, jacket foundation, gravity foundation and composite tube foundation. Compared with other foundations, the composite tube foundation has low cost of basic materials and high rigidity. Its one-step installation technology can shorten the construction period. The large-scale gantry crane is hoisted into the water, and then floated and transported to the designated place by a special ship for installation. The purchase of large-scale gantry cranes is expensive, and the composite cylinder foundation is large (30 to 50 meters in diameter), and the wharf area needs to be large, which increases the composite cylinder foundation...
