PILE PRESS-IN DEVICE AND PILE PRESS-IN METHOD

ONO MASAAKI / ONO KATSUHIKO / MORIOKA YOSHIHIRO / NONAKA KENGO

Provided are a pile press-in device and a pile press-in method that allow efficient construction even if electric motors and hydraulic devices are used together in order to impart a driving force on a driving member. A pile press-in device (1) comprises a chuck (5) that holds and rotates a pile (4) in order to press the pile (4) into the ground while rotating same. The pile press-in device (1) applies a driving force for rotating the chuck (5) by way of an electric motor (6) that corresponds to the electric motor of the present invention. The chuck (5) moves vertically by way of a lift cylinder (7) that is a hydraulic device operating by hydraulic pressure. An integrated control panel (50) links and controls the electric motor (6) and the lift cylinder (7).

本发明提供一种即使为了向驱动构件提供驱动力而电动机与油压装置混合存在，也能实现高效施工的压桩装置及压桩方法。压桩装置(1)为了一边旋转桩(4)一边将其压入地面，而具备夹持桩(4)并使其旋转的夹头(5)。压桩装置(1)由相当于本发明的电动机的电动电机(6)提供用于使夹头(5)旋转的驱动力。夹头(5)通过以油压工作的油压装置即升降缸(7)而上下移动。综合控制盘(50)控制电动电机(6)与升降缸(7)联动。
