JACKET LEG-CAN JACKET STRUCTURE THEREWITH AT SOFT SOIL SEABED DURING OFFSHORE CONSTRUCTION AND CONSTRUCTION METHOD THEREFOR

摘要

The present invention relates to a jacket structure having a jacket leg can which can stably form a fixed end on a soft ground, can securely be constructed using a consolidation effect, and can protect the jacket leg, and a method of constructing the jacket structure. Wherein the jacket structure comprises: a hollow tube for receiving a lower end of the jacket leg into an upper portion of the jacket structure; The hollow tube is divided into an upper space (S1) and a lower space (S2) by a plate member formed on the inner surface of the hollow tube. The lower end of the jacket leg is fixedly coupled to the upper surface of the inner intermediate partition Inner side walls; And a restraining concrete filled in the upper space S1 of the inner middle partition wall and embedded in the jacket leg fixed on the upper surface of the inner middle partition wall.
