The utility model discloses a dive-controllable high pulling resistance pile based on a marine oil column-type platform principle. The dive-controllable high pulling resistance pile based on the marine oil column-type platform principle is the steel or reinforced concrete square or circular pile, the longitudinal section is H-shaped, namely upper and lower cabins are opened; the top of the lower cabin is embedded with two mud pipes with quick couplers which are higher than the top of the upper cabin, and is opened with several rows of limber holes; an airbag with a pneumatic control valve is bound; the floating force is controlled by adjusting the exhaust of the airbag; the airbag is taken back after the pile dives to the mud surface, and heavy blocks are thrown to the upper cabin; and in the same principle, the top of the upper cabin can be closed, the limber holes are closed or the limber holes are not installed, and the top is equipped with a sand pipe or a drain pipe. Because the weight is big, and the surface area of the outer wall of the pile is large, the pulling resistance of the pile is improved under the same geological conditions.
