MOORING COLUMN OF FLOATING PIER AND WATER-SURFACE FLOATING STRUCTURE

PURPOSE:To install and remove a floating pier, etc., arbitrarily to and from a mooring column by mounting the mooring column from a fixed pile built on a sea-bottom ground and a mooring pile fixed by being detachably fitted to an upper section and projected on the sea. CONSTITUTION:Mooring piles 2-2 are fastened detachably to fixed piles 2-1 and mooring columns 2 are formed in the fixed piles 2-1 built on a sea-bottom ground 3, thus installing a floating pier. The fixed piles 2-1 can be fixed to the sea-bottom ground 3 and the mooring piles 2-2 into the upper-end hollow sections of the fixed piles 2-1 by detachably inserting the mooring piles 2-2. In the mooring columns 2, flanges 4-1 set up to the upper ends of the fixed piles 2-1 and flanges 4-2 mounted to mooring-pile 2-2 fitting sections are abutted and fastened to the fixed piles 2-1. Otherwise, a plurality of strips of spacers projected in the radial direction on the outer circumferential surfaces of the mooring piles 2-2 are installed, and the front ends of the spacers are inserted and fastened along the internal surfaces of the fixed piles 2-1. Accordingly, a water-surface floating structure such as the floating pier can be utilized under proper conditions.
