Suction bucket foundation using vacuum preloading method
The present invention relates to a suction foundation using a vacuum preloading method, a construction method thereof, and a foundation improvement method using the suction foundation. More specifically, the suction foundation comprises a suction foundation and a vacuum preloading apparatus. The suction foundation has a main body and a suction means. The main body comprises: an upper portion covered with an upper plate, a lower portion formed in an open hollow column shape, and a column surface composed of a skirt portion penetrated into the seabed ground. The suction means is provided on one side of the upper plate to drain seawater inside the main body. The vacuum preloading apparatus is provided on one side of the suction foundation and drains pore water in the seabed ground around the suction foundation using vacuum pressure. Accordingly, the present invention provides a suction foundation to enable improvements of the foundation and construction of the suction foundation to be performed at the same time; and prevents settlement due to consolidation.
진공압밀공법을 이용한 석션기초, 그 석션기초의 시공방법 및 그 석션기초를 적용한 지반개량공법에 대한 것이다. 보다 상세하게는, 석션기초에 있어서, 상부는 상판으로 덮여있고 하부는 개방된 중공의 기둥형태로 구성되며 기둥면은 해저지반에 관입되는 스커트부로 구성된 본체와, 상기 상판 일측에 구비되어 본체 내부의 해수를 배수시키는 석션수단을 갖는 석션기초; 및 상기 석션기초 일측에 구비되고, 진공압을 작용시켜 관입된 상기 석션기초 주변의 해저지반 내의 간극수를 배수시키는 진공압밀장치를 포함하는 것을 특징으로 하는 진공압밀공법을 이용한 석션기초에 관한 것이다.
