ADDITIONAL PENETRATION METHOD FOR SUCTION PILE USING WATER-JET AND THE SAME SUCTION PILE

摘要

The present invention relates to an additional penetration method of a suction pile using water jet, which prevents heaving of soil and enables the suction pile to additionally penetrate up to design depth, when the suction pipe penetrates into the soil, and to the suction pile thereof. The additional penetration method is performed by the suction pile. The suction pile comprises an hollow part having a sealed upper end and an opened lower end; an outlet which is formed on the upper end of the hollow part and connected to a suction pump capable of suctioning the inside of the hollow part; a protruding pipe supplying water from the upper end to the upper side of the inside of the hollow part; and a hydraulic pump which supplies water for water jet and is connected to the protruding pipe.
