Embodiment 1

[0056] like 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] like 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 components sho...

Abstract

The invention relates to an offshore wind power combined type single pile foundation and a construction method thereof. The combined type single pile foundation comprises a steel pipe pile and a plurality of variable-section T-shaped wing plates; mortise grooves matched with the variable-section T-shaped wing plates in quantity are formed in the outer surface of the steel pipe pile in the verticaldirection, and tenons matched with the mortise grooves are arranged on the variable-section T-shaped wing plates so that the variable-section T-shaped wing plates and the steel pipe pile are fixedlyconnected through mortise and tenon joint structures composed of the mortise grooves and the tenons. Compared with the prior art, according to the single pile foundation and the method, the problem ofvertical deviation rectification of single pile foundations can be solved to a certain extent, the applicability of the single pile foundation in a deepwater sea area is improved, and the single pilefoundation and the method have the advantages of high overturning resistance, high bearing capacity, convenient construction, and good economic benefit.

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...
