COLUMNAR IMPROVEMENT PILE CONSTRUCTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a columnar improvement pile construction system which allows: a construction pattern for automatic operation to be created outside a ground improvement work machine; and the ground improvement work machine to perform the automatic operation by reading the construction pattern.SOLUTION: A columnar improvement pile construction system comprises: a ground improvement work machine which has an agitation tool to construct a columnar improvement pile in the ground, a rod with the agitation tool fixed to a lower edge section thereof, a rotation drive section which rotationally drives the agitation tool, a vertical drive section which upwardly or downwardly drives the agitation tool, a ground improvement agent supply section which supplies a ground improvement agent, and an automatic operation setting section for setting construction data necessary to construct the columnar improvement pile; and a process setting device which allows the construction data necessary for constructing the columnar improvement pile through automatic operation of the ground improvement work machine to be set outside the ground improvement work machine and can record the construction data as a construction pattern. The automatic operation setting section can input and utilize the construction pattern recorded by the process setting device for constructing the columnar improvement pile through the automatic operation.SELECTED DRAWING: Figure 5
