PURPOSE:To enable a foundation bed plate and a foundation pile to be coupled with each other in a dry condition, by a method wherein the head part of the foundation pile is contained in the cylinder body of the foundation bed plate, and after water in the cylinder body is drained, a filling material is pressed in to couple together the foundation bed plate and the head part of the foundation pile. CONSTITUTION:When a foundation bed plate 2 is installed on a sea bottom surface 3, the head part of a pile 1 is contained in a cylinder body 5, and the lower end of the cylinder body 5 is penetrated into a sea bottom ground 8 by length equivalent to length by which it is protruded. The air is pressed in through a pipe 6, and water between the cylinder body 5 and the pile 1 is drained through a pipe 7. A filling material 16, such as concrete, mortar, is pressed in through the pipe 7 under a pressurized state, and the pipes 6 and 7 are cut in a portion in the vicinity of the foundation bed plate 2. This improves reliability on the filling material pressed in, and enables the head part of the foundation pile and the foundation bed plate to be reliably coupled with each other and in a dry state. |
