CONSTRUCTION OF HIGH BEARING FORCE CAST-IN-PLACE CONCRETE PILE ETC.

摘要

PURPOSE:To strengthen a head edge bearing power by way of fixing a tamping pile by introducing a guide pipe provided with the tamping pile in a desired depth, and filling in-filling mortar in the guide pipe. CONSTITUTION:In advance of construction of a body 11, the head edge opening is covered with a cover plate 7 capable of knockout, and a guide pipe 4 installed with a tamping pile 6 by way of screwing a male screw part of the tamping pile 6 in a female screw part on the head edge inner surface is set on the bottom of a head edge ground 5. Conversely, after completion of the body 11, a rotary shaft is inserted to the inside of the guide pipe 4, and the tamping pile 6 is rotated and intruded to the head edge ground 5. Thereafter, the in- filling mortar is filled in the guide pipe 4. Consequently, it is possible to produce a high bearing force cast-in-place concrete pile with large head edge bearing power.
