ANCHOR FOR ANCHORING VESSEL AND FIXING CONSTRUCTION FOR ANCHOR ONTO SEA BOTTOM

摘要

PURPOSE:To permit the sure anchoring of a floating article on the sea and reduce the installation space on the sea bottom by embedding an anchor onto the sea bottom and fixing said anchor by mortar and allowing at least the engagement part of an anchor cable to be exposed from the sea bottom. CONSTITUTION:When an anchor 10 is to be installed, a drilled hole 2 having a prescribed depth is formed on the sea bottom 1 by a boring machine installed on a working vessel. Then, a cylindrical caisson 3 and a bottom cover 4 are pulled up by wires 5 and 6, and in the state in which the bottom of the caisson 3 is closed by the bottom cover 4, the inside of the caisson 3 is filled with mortar 7 on the vessel, and the integrally formed articles are submerged to the sea bottom, and fitted into the drilled hole 2. Then, the wire 5 is separated, and the caisson 3 is pulled up by a crane, leaving the bottom cover 4. Then, the eyebolt-shaped anchor 10 having a template 11 for preventing mortar washing is inserted into the drilled hole 2, and the leg part of the anchor is pushed into the mortar 7 in the drilled hole 2. Then, the anchor 10 is supported by the wire 4 laid between the piles 13 struck onto the sea bottom, and the oscillation is prevented.
