The invention provides an offshore strong-stormy-wave high-intensity bare rock steel pipe pile foundation method which comprises the following steps that (1) four integrated triangular supports groups are machined on the bank; (2) a barge is used for conveying one of the triangular supports to a pier position, and sinking in place is carried out; (3) a steel pipe pile is inserted into a triangular support steel pipe in a striking mode; (4) after triangular support inserting striking is completed, the steel pipe is cut to the designed elevation, a horizontal beam is arranged at the top of the steel pipe; (5) the step (2), the step (3) and the step (4) are repeated, the other three triangular supports are subjected to the same operation; (6) a construction platform is machined and manufactured on the bank and is conveyed to the pier position; (7) the construction platform is put down to the top faces of the triangular supports and is fixed; (8) according to a mounted construction platform sleeve pipe position, platform pile punching is carried out, and a platform pile is inserted; and (9) underwater concrete is filled into the construction platform pile, cycle operation is carried out, and mounting is completed. The offshore strong-stormy-wave high-intensity bare rock steel pipe pile foundation method has the advantages that whole platform stability and firmness are guaranteed, the position and the overall stability of a steel pipe pile foundation can be effectively controlled, the construction cycle can be shortened, and construction investment is lowered.
