Embedding construction method of the light-gage steel pipe pile and is used for this the light-gage steel pipe pile

摘要

PURPOSE: To thin a steel pipe pile with a blade to be rotated and embedded. ;CONSTITUTION: A reinforcement body C provided with a thin wall tube 11 is fitted closely into the head end of a steel pipe pile A at the bottom of which a bottom plate 2, drilling edges 3 and 3, and large-diameter spiral blade 4 are provided and at the head of which hook pieces 5 and 5 are provided, a rotating cap B in which locking grooves 9 and 9 which engage with the hook pieces 5 and 5 is covered on it, and a steel pipe pile A is screwed into the ground by rotating and pressing the rotating cap B to bury it. Thus the head of the steel pipe pile A subjected to a rotational force is strengthened by the presence of the thin wall pipe 11, and deformation due to torsional force is suppressed.;COPYRIGHT: (C)1995,JPO
