Construction method of pier structure and pier structure

摘要

An object of the present invention is to provide a method of constructing a pier structure capable of improving workability, and a pier structure. A method of constructing a pier structure 100 is a method of constructing a pier structure 100 including a pier girder 1 supported by a main pile 2, the pier structure forming a part of the pier girder 1. A lifting step S10 for lifting the girder unit 10 and a connecting step S20 for connecting the pier girder unit 10 to an end of the existing pier girder 200 in the extending direction D1 are provided. The pier girder unit 10 is lifted in a state where the first temporary pile 6 is provided at a position on the center side in the extension direction D1 of the ten, and in the connecting step S20, the lower end of the first temporary pile 6 is supported on the ground G. The height of the pier girder unit 10 is adjusted along the first temporary pile 6. [Selection diagram] FIG.
