CAST-IN-PLACE CONSTRUCTION METHOD OF CONCRETE PILE

摘要

The present invention relates to a cast-in-place construction method, and more particularly, to a construction method of cast-in place continuous pile using a mold for cast-in-place pile. The cast-in-place construction method comprises: a step (a) for inserting an outer casing, while drilling the ground using a punch; a step (b) for installing a mold for cast-in-place pile inside the installed outer casing; a step (c) for withdrawing the outer casing; a step (d) for inserting the outer casing, while drilling the ground using a punch to be in contact with an interface of the auxiliary casing; a step (e) for installing the mold for cast-in-place pile inside the installed outer casing; a step (f) for withdrawing the outer casing; a step (g) for continuously installing the mold for cast-in-place pile by repeatedly performing the step (d) to the step (f); a step (h) for placing concrete inside the inner casing; and a step (i) for filling concrete inside the inner casing while withdrawing the pre-installed a plurality of mold for cast-in-place piles. According to the present invention, after a cast-in-place construction method is performed in a number of times, an auxiliary casing for forming a connection portion with an adjacent pile is only replaced, and an inner casing can be recycled. Therefore, as compared with the case in which the whole casing is replaced, construction costs can be reduced.;COPYRIGHT KIPO 2019
