SUCTION FOUNDATION WITH ENHANCED SELF WEIGHT PENETRATION AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a suction foundation for providing a basic supporting force while being stuck in a seabed ground by a vacuum pressure of a suction pump. The suction foundation is formed in a hollow shape having an opening at its lower end and is seated on the seabed ground by its own weight, A hollow caisson which receives the fluid in the inner hollow and which is connected to the suction pump and discharges the inner hollow fluid through the vacuum pressure of the suction pump, A bottom skirt formed in a wedge-shaped cross section and having a wave shape repeated along the periphery of the opening of the hollow caisson, and penetrating the bottom of the seabed through the convex portion during initial seating by the self weight of the hollow caisson; And a stiffener for reinforcing the rigidity of the lower skirt while expanding a thickness of a part of the lower skirt.;
