The invention provides an offshore wind power plant draught fan combined-type rock-socketed pile foundation. The offshore wind power plant draught fan combined-type rock-socketed pile foundation comprises steel pipe piles, cast-in-place piles and anchor rods. The lower ends of the steel pipe piles are arranged in a covering layer of a marine foundation in a penetrating mode, the cast-in-place piles are arranged in an intensive weathered layer of the marine foundation in a penetrating mode, and the upper ends of the cast-in-place piles stretch inside the steel pipe piles and are anchored to the inner walls of the steel pipe piles. The anchor rods are fixed to medium-weak weathered rocks of the marine foundation in an embedded mode, and the upper ends of the anchor rods stretch inside the cast-in-place piles and are anchored to the inner walls of the cast-in-place piles. Due to the facts that the steel pipe piles penetrate in the covering layer and the cast-in-place piles penetrate in the intensive weathered layer, the risk that the steel pipe piles cannot be sunk to a design elevation is relieved greatly. At the same time, the anchor rods are fixed to the medium-weak weathered rocks in the embedded mode, so that the construction efficiency of socketed rocks is improved greatly, and the construction risk of the socketed rocks is reduced. The invention further provides a construction method of the offshore wind power plant draught fan combined-type rock-socketed pile foundation. According to the construction method, the construction quality of the offshore wind power plant draught fan combined-type rock-socketed pile foundation can be ensured, and the construction efficiency is improved.
