EXCAVATED SHAPE CONFIRMATION DEVICE AND EXCAVATED SHAPE CONFIRMING METHOD
To provide an excavated shape confirmation device allowing efficient confirmation of the shape of an excavated hole.SOLUTION: An excavated shape confirmation device 1 is used for confirming the excavated shape of an excavated hole for burying a concrete pile, and comprises an excavation device 2 excavating the ground and electrode parts 8 proceeding in the ground following the excavation progress of the excavation device 2 into the ground. The electrode part 8 has current electrodes 11 carrying a current and an electrode unit 9 having voltage electrodes 12 for measuring the voltage. In the electrode unit 9, the current electrodes 11 and the voltage electrodes 12 are arranged with equal intervals, respectively. A specific resistance is calculated on the basis of a current value of the current electrodes 11, a voltage value at the voltage electrodes 12 and an electrode interval value, and a boundary part of a stratum is detected by the specific resistance.SELECTED DRAWING: Figure 1
