APPARATUS FOR INCREASING A SUPPORTING FORCE OF A PILE FOR A MARINE SAND GROUND SURFACE, AND METHOD FOR CONSTRUCTING THE PILE

摘要

The present invention relates to an apparatus for increasing a supporting force of a pile for a marine sand ground surface. The apparatus for increasing the supporting force of the pile for a marine sand ground surface includes a solid-type or hollow-type pile, on which an observing device or structure having a predetermined function is disposed on an upper portion thereof, and which is inserted into the marine sand ground surface under the sea. Here, at least one wing member is rotatably coupled to the pile. For example, when the pile is inserted, the wing member is folded so that the wing member is closely attached to an outer circumference of the pile. Also, the pile is drawn or extruded, the wing member is unfolded to increase a supporting force of the pile.
