The present invention provides a jacket structure with enhanced pull-out resistance, which has a plate-shaped precast reinforced concrete structure, comprising: a jacket unit, which supports an offshore wind structure; a pile unit, which is coupled with the lower part of the jacket unit and supports the jacket unit while being embedded into the ocean floor; and a connection member, which is coupled with the lower part of the jacket unit and makes all of multiple piles, which are equipped in the pile unit, move. The pile unit comprises a central pile, which is arranged at the center of the lower part of the jacket unit and uniformly supports any pull-out load applied from the front; and multiple outer piles, which are arranged on the outer area of the jacket unit and support the central pile. The outer piles are shorter than the central pile and are embedded at a shallow depth, considering the maximum compressive load applied to the pile unit, and have smaller diameter than the central pile. The connection member includes a central mounting hole where the central pile is installed; and an outer mounting hole where the outer piles are installed. According to the present invention, the jacket structure is available in an area where water is deep and can effectively support the pull-out load applied to the lower part of the offshore wind structure from the front. |
