COLUMN BUILDING DEVICE AND COLUMN BUILDING VEHICLE

摘要

PROBLEM TO BE SOLVED: To firmly hold an attitude of a support column which guides the vertical travel of an auger decelerator. ;SOLUTION: When an auger device 18 as a pile member is embedded in the ground, downward load is applied to an auger decelerator 16 guided by a support column 15. At this time, reaction force acting from the ground surface GR and the underground is supported by a boom tip 21a on an extension line of the action line. As a result, load in the horizontal direction is not applied to the boom tip 21a to suppress the inclination and the movement of the support column 15 and a boom 21. The vertical attitude of the auger device 18 is maintained, and the auger device 18 is vertically embedded in the ground.;COPYRIGHT: (C)1999,JPO
