The invention belongs to the technical field of drilling construction on the water surface, and particularly relates to rotary excavating drilling hole guiding equipment for an overwater buoyancy tank platform and a construction method.The rotary excavating drilling hole guiding equipment comprises a buoyancy tank, a ship, an anchoring device and a guiding device.The buoyancy tank and the ship are located on the water surface, and the horizontal projection of the buoyancy tank is a rectangle protruding out of the ship; a rotary drilling rig is arranged on the floating box, the floating box and the ship are fixedly or detachably connected, the anchoring devices are installed on the floating box and the ship respectively and can fix the floating box and the ship to a water surface construction operation part, and a guiding device is installed on the floating box. The construction method mainly comprises the steps of platform preparation, platform leveling and anchoring, pile center point determination, drilling and concrete pouring and steel pipe pile pressing. Compared with the prior art, the construction safety is greatly guaranteed, the problem that the construction working face of the steel pipe pile is limited is solved, and the construction efficiency of the water steel pipe pile is improved.
