*森山 貞文¹ (1. 九鉄工業)

Keywords:Location punching pile, Test construction

The test construction was conducted by the all-casing construction method on the basis of the investigation boring performed at the design stage, but the support layer was very hard and drilling became impossible along the way. In order to select a method that can be excavated, a method that can be constructed was selected based on multiple test constructions.
