CONTROL DEVICE FOR FORMING CRUSHED STONE PILE AND METHOD FOR FORMING CRUSHED STONE PILE

摘要

PROBLEM TO BE SOLVED: To provide a control device for forming a crushed stone pile, capable of surely forming a crushed stone pile of uniform quality without imposing burden on an operator, and a method for forming the crushed stone pile.;SOLUTION: A control device for forming a crushed stone pile comprises: depth detection means; torque detection means; data display means for displaying depth data detected by the depth detection means and torque data detected by the torque detection means; construction condition setting means for setting the construction condition of the crushed stone pile; and information output means comparing a compaction torque set value preset by the construction condition setting means with the torque data detected by the torque detection means in a compaction step for compacting the crushed stone supplied into an excavation hole, outputting compaction torque arrival information when the torque data reaches a compaction torque set value or higher, and outputting rise amount arrival information when a rise amount set value preset by the construction condition setting means is compared with a rise amount calculated from change in the depth data and the calculated rise amount reaches the rise amount set value or higher.;COPYRIGHT: (C)2013,JPO&INPIT
