Abstract

To provide a pier construction method that enables bridge construction to continue even during river flood season.SOLUTION: A pier construction method constructs a pier 3 to be used in a construction of a bridge crossing a river 9. The pier construction method includes a pier substructure construction step of constructing a pier substructure 30 at a height equal to or higher than the planned high water level (HWL) of the river 9 and equal to or lower than a height equal to that of an existing substructure 10, at positions spaced apart in the flow direction of the river 9 and spaced apart approximately the same as that of the existing substructure 10 of the bridge in the bridge axis direction, and a pier erection step of constructing the pier 3 by installing an erection girder 33 on the pier substructure 30 along the bridge axis direction.SELECTED DRAWING: Figure 8
