Title:
PILE PRESSING METHOD AND PILE PRESSING APPARATUS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/125441
Kind Code:
A1
Abstract:
Disclosed in the present invention is a pile pressing method comprising: a primary pressing step of transporting a first pile (11) of a plurality of piles (10) so as to support same in an erect state on the pressing point of the ground, and pressurizing the first pile (11) so as to press same into the ground; a secondary pressing step of transporting a second pile (12) of the plurality of piles (10) so as to support same in an erect state on the pressing point of the ground, coupling the lower end of the second pile (12) to the upper end of the first pile (11), and pressurizing the second pile (12) so as to press same into the ground; a continuous pressing step of pressing, by means of a method which is the same as that of the secondary pressing step, the plurality of piles (10) into the ground while sequentially coupling same; a target load (W1) and target speed setting step of respectively setting, as a target load (W1) and a target speed (v1), a pressing load (W) and a pressing speed (v) when a state in which the support strength of a pile base structure is ensured is reached; and a pressing operation completion step of completing the continuous pressing step when the measured pressing load (W) of the pile (10) reaches the preset target load (W1) and the measured pressing speed (v) of the pile (10) reaches the preset target speed (v1) during the continuous pressing step, and thus the present invention can easily ensure the structural stability of all of the plurality of constructed pile base structures.
