Abstract
PURPOSE: To reduce the resistance when a pile struck in and increase the supporting force by being opened after its striking is completed by making the pile form into a cone shape when its tip is closed and into an inverted T-shaped body when it is opened.
CONSTITUTION: When a pile struck in the ground reaches the aimed depth, a pin 8 for fixation is drawn out by pulling a pulling-out wire 9 and the pile is pulled up by the required length. At first, a double-nail body 3-3' is opened by the force of the 1st spring 12 and the tips of nails strike against an earth wall at the right and left. When the pile struck again, the nail body 3-3' opens, cutting into the earth wall, by the force of the 2nd spring 13 as well as the pressure-resisting force of the ground given to the inside faces of the nails 3 and 3', and fully opens in the end. When the nail body fully opens, the striking of the pile is stopped and concrete or grout is poured into the pile to fill in pinholes, while the ground is filled up through a piercing hole 7 made at the tip of the pile.
