The invention discloses a bionic razor clam self-tapping type deep sea anchoring foundation and a construction method, and relates to the technical field of ocean engineering equipment, the bionic razor clam self-tapping type deep sea anchoring foundation comprises a shell, a center cylinder, a sand discharging mechanism, a conical drill bit, a driving mechanism, a water diversion assembly and a centralizing device, the shell is in an ellipsoid shape with two open ends, and the center cylinder is vertically and fixedly arranged on the inner side of the shell in a penetrating mode. The sand discharging mechanism is arranged in the center cylinder and comprises a spiral shaft and a spiral blade, the conical drill bit is installed at the lower end of the spiral shaft, the water diversion assembly comprises a plurality of water diversion pipes vertically arranged in the shell in a penetrating mode, and the two ends of each water diversion pipe penetrate out of the shell and are detachably and fixedly connected with the shell. The driving mechanism comprises a waterproof motor and a transmission shaft, and the waterproof motor is fixed to the upper end of each water conduit through a motor support to drive the spiral shaft to rotate. The self-tapping type deep sea anchoring foundation is provided with a centralizing device. According to the self-tapping deep sea anchoring foundation, the water injection impact and soil discharging penetration mode is adopted, the penetration efficiency of the self-tapping deep sea anchoring foundation is high, large equipment is not needed in the construction process, the construction cost is low, and the embedding depth is not limited.
