Novel type pile foundation for sea turn engineering and pile forming method thereof

Abstract

The invention discloses a novel type pile foundation for sea turn engineering and a pile forming method thereof. The novel type pile foundation comprises a steel pipe, the steel pipe is internally provided with a concrete lining pipe; a corrosion preventive is coated outside the steel pipe; the concrete lining pipe is internally provided with a reinforced concrete pile core, and the lower end of a steel bar inside the pile core penetrates out of a through hole positioned on a pointed cone at the lower end of the steel pipe and extends to sea bed rocks; the steel bar wrapped with concrete and penetrating outside the pointed cone passes through a concrete extrusion through hole positioned below the steel bar penetrating through hole on the pointed cone and is connected with the reinforced concrete pile core inside the concrete lining pipe through to form an expanded pile head. The novel type pile foundation for the sea turn engineering forms a chassis in a large head shape and with the radial dimension larger than that of the main body part of the pile foundation at the bottom of the main body of the pile foundation, is closely combined with the sea bed rock and has very high pressure and drawing resisting capability; and in addition, the pile forming method ensures the smooth construction on the sea.

Description

technical field [0001] The invention relates to a new pile foundation for offshore wind engineering, in particular to a pile foundation with high bearing capacity. Background technique [0002] Wind energy is a green energy advocated by our country. In recent years, my country's wind power has developed rapidly, and the country's cumulative installed capacity has exceeded 6 million kilowatts. However, there is a serious mismatch between the distribution of wind energy resources and the demand for electricity in my country: the demand for electricity in the southeast coastal areas is large, and wind farms are easily connected, but land resources in the coastal areas are tight, and the area available for building wind farms is limited; the northeast, north, and northwest regions Wind resources are abundant, and the area that can be used to build wind farms is relatively large, but the construction of the power grid is relatively weak, and the power demand is relatively small, ...

AI Technical Summary

Problems solved by technology

This requires the pile foundation of the offshore wind project to be particularly large and expensive

In addition, the pile foundation of the offshore wind project cannot be formed underwater, because there is an ocean current, and the concrete will be washed away by the ocean current before it is formed.
