PURPOSE:To save the cost of construction work by a method in which an inner pile is inserted into a hollow pile, concrete is packed into the hollow to form a blocked supporter on the tip of the pile, and deformed water-dissipating blocks are orderly stacked up on the seabed through the central through holes. CONSTITUTION:A tip-open type hollow pile 13 is driven to the ground 11, the core in the pile 13 is pulled up, and an inner pile 14 of H-shaped steel, etc., is hung down to a given position into the hollow. While pouring concrete 15 into the pile 13, a blocked supporter 16 like a bulb is formed on the tip of the pile 13. Deformed wave-dissipating blocks 17 are orderly stacked up in a spitted manner on the seabed while inserting the pile 13 into the through holes of the blocks and fixed with concrete 18. The tips of the inner piles 14 are connected fixed with connectors 20, e.g., beams, girders, etc. Since the need to construct given foundations in water is eliminated, the construction work can be performed from the water surface. |
