Document Type and Number:
Japanese Patent JP2019065642
Kind Code:
A
Abstract:
To make it possible to construct a steel pipe pile in the ground without causing scratches on surrounding piles.SOLUTION: A tip of a mounting structure 4 for an excavation blade of a steel pipe pile is provided with excavation blades 5 excavating the ground. In the excavation blade 5, a protruding dimension (a) to the outside of an outer peripheral surface of the steel pipe pile (a between-piles pipe 3) is within 3 mm. The steel pipe pile is, for example, the between-piles pipe 3 which has a diameter smaller than a main pile 2, for constituting a continuous wall by installing it between the main piles 2 arranged at intervals. The steel pipe pile can be constructed in the ground while making it close to the surrounding main piles 2 that have already been constructed without causing scratches on the main piles 2.SELECTED DRAWING: Figure 4
