METHOD OF MANAGING DRIVE STOP OF BOARD DRAIN, AND BOARD DRAIN CONSTRUCTING MACHINE

摘要

PROBLEM TO BE SOLVED: To appropriately decide a drive depth of a board drain without increasing the cost. SOLUTION: A soil exploration electrical static cone 7 is driven into the ground to grasp a ground layer at this ground point on the basis of the exploration data obtained by the electrical static cone 7 and to obtain the first correlation data showing a correlation between the data showing a change of the drive resistance of the electrical static cone 7 and a change of the ground layer. A board drain is driven for a test near the drive ground point of the electrical static cone 7 to obtain the second correlation data by comparing the data showing the drive resistance when test-driving with the first correlation data. A board drain is probe-driven at plural points separated from the test drive point, and a ground layer of the probe-drive point is estimated on the basis of a comparison between a change of the drive resistance when probe-driving and the second correlation data, and a drive stop management value of the board drain is decided on the basis of the data obtained by the test-drive and the probe- drive.
