Embodiment Construction

[0023] Such as Figure 1~Figure 6 Among them, an anchoring foundation suitable for floating wind turbines, which includes an anti-sinking plate 1, a flange 2, a spiral anchor 3 and an anchor chain assembly 4; the upper end of the spiral anchor 3 is connected to the lower side of the flange 2, the method The blue 2 is connected to the anti-sinking plate 1, and the anchor chain assembly 4 is connected to the anti-sinking plate 1; there are multiple spiral pieces on the spiral anchor 3; the plurality of spiral anchors 3 are arranged in a triangle, and the anchor cable 43 connected by the anchor chain assembly 4 Extend upward toward the center of the triangle.

[0024] Preferably, compared with other foundation types, the spiral anchor foundation has the advantages of fast installation, strong pull-out resistance, and easy recycling and reuse.

[0025] Preferably, ordinary spiral anchors need to apply a relatively large torque to penetrate into the soil, while the torque required...

Abstract

The invention provides an anchoring foundation suitable for a floating type fan and a construction method of the anchoring foundation, which comprises an anti-sinking plate, a flange, spiral anchors and an anchor chain assembly, the flange is arranged on the lower portion of the anti-sinking plate, the flange is connected with the anti-sinking plate and the spiral anchors, the anchor chain assembly is fixedly connected with the upper side face of the anti-sinking plate, and the multiple spiral anchors are arranged in a triangular shape. An anchor cable connected with anchor chain assembly extends upwards towards center of triangle to be connected with platform. According to the invention, the problems that an original traditional floating platform mooring tension balancing structure is complex in installation process and high in manufacturing cost are solved, and the floating platform mooring tension balancing structure has the advantages of being simple in construction process, high in construction efficiency, convenient to assemble and transport, low in cost and easy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power foundations, and relates to an anchor foundation suitable for floating wind turbines and a construction method thereof. Background technique [0002] my country has accelerated social development in recent decades, especially in energy utilization. In the past 30 years, with the increasing demand for oil and gas resources, oil and gas exploitation has become saturated, and the harmful gases produced by the combustion of fossil energy such as oil and gas will cause certain harm to the human living environment. Since the new century, clean wind energy resources have gradually become the focus of new energy development. [0003] Compared with onshore wind power, offshore wind power is more stable, closer to coastal power consumption centers, and has a longer annual utilization time. The current offshore wind power foundation is mainly a fixed structure in shallow sea areas, but as the o...
