Embodiment 1

[0056] Such as Figure 1 to Figure 5 As shown, the combined single-pile foundation includes a steel pipe pile 1 with a mortise 52, four variable-section T-shaped wing plates 2 with a mortise 51, a flat-bottomed open pile point 3, and a long cross-shaped Stiffener 4, mortise and tenon structure 5 that is easy to form reliable connection, auxiliary vertical correction mechanical parts (including jack 8, etc.)

[0057] Such as figure 1 As shown, the steel pipe pile 1 is provided with four longitudinal mortise grooves 52 so as to be reliably connected with the variable-section T-shaped wing plate 2 with a tenon 51. The bottom end of the steel pipe pile 1 should be at On land, the flat-bottomed open pile tip 3 is welded in advance to assist pile sinking, and the steel pipe pile 1 is provided with a long cross-shaped stiffener 4 to improve the bending stiffness of the single pile foundation and increase the bearing capacity . The above-mentioned steel pipe pile 1 and its componen...

Abstract

The invention relates to a combined single pile foundation for offshore wind power and a construction method thereof. The combined single pile foundation includes steel pipe piles and several T-shaped wing plates with variable cross-sections. The outer surface of the steel pipe piles is arranged vertically. There are a number of mortises matching the variable-section T-shaped flange, and the variable-section T-shaped flange is provided with a tenon matching the mortise, so that the passage between the variable-section T-shaped flange and the steel pipe pile The mortise and tenon structure composed of mortise and tenon is fixedly connected. Compared with the prior art, the present invention can solve the problem of vertical rectification of the single pile foundation to a certain extent, improve the applicability of the single pile foundation in deep water sea areas, and has high anti-overturning ability, high bearing capacity, convenient construction, good economic benefits, etc. advantage.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power foundations, and relates to an offshore wind power combined single pile foundation and a construction method thereof. Background technique [0002] Energy is the foundation of modern society and economic development. However, with the growth of population and the development of social economy, the consumption of energy is also increasing rapidly, and the energy crisis is gradually emerging. The development of clean and efficient renewable energy is the strategic goal of the development of countries all over the world. As a renewable energy, wind energy is one of the new energy sources that countries focus on. As a kind of wind energy utilization, offshore wind power generation has developed rapidly in recent years. It has most of the advantages of onshore wind power generation, and has the advantages of large power generation, less use restrictions, and no land occupation. [0003] La...
