<p>PROBLEM TO BE SOLVED: To provide a pier construction method capable of reducing a work burden of a diver when constructing a pier on the water.SOLUTION: In the pier construction method of the present invention, a pile material 4 is hung down and temporarily driven via guide materials 1 and 2, and next, the temporarily driven pile material 4 is pulled out once, and is hung up while guiding by the guide materials. An installation expected position of a fixation member used for fixing a lower structural reinforcement material is marked on the pile material in a process of hanging up the pile material 4. Then, the marked pile material 4 is hung down while guiding by the guide materials 1 and 2, and a ring-shaped fixation member (a member for fixing the reinforcement material) is installed at the marked position in the pile material in the middle of hanging down. The pile material 4 successively installing the ring-shaped fixation member is hung down via the guide materials 1 and 2, and is built up again in a driving position. Trouble by which the diver determines an installation position of the reinforcement material fixation member in the water is omitted by this method, an underwater work amount of the diver is reduced, and working efficiency is improved.</p> |
