DEVICE AND METHOD FOR CONFIRMING VERTICAL BEARING CAPACITY OF PILE

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for confirming vertical bearing capacity of a pile capable of accurately confirming the vertical bearing capacity when the pile is constructed before constructing the same.SOLUTION: A device 1 for confirming vertical bearing capacity of a pile comprises: a body 3 made of a steel pile; a spiral blade 5 attached to a tip section of the body 3; a bottom plate 7 installed at the tip section of the body 3 in a manner that closes a tip opening; an inner pipe 11 which is made of a steel pipe with a tip end thereof fixed to an upper face side of the bottom plate 7 and the other end thereof fixed to an annular plate 9 on an inner face of the body 3; a distortion meter which measures distortion of the inner pipe 11 in an axial direction; and a calculation device 19 which calculates penetration resistance Pgenerated on the bottom plate 7 on the basis of the distortion on the inner pipe 11 measured by the distortion meter.SELECTED DRAWING: Figure 1
