Abstract

PURPOSE: To enable to easily measure an excavator tip displacement quantity by receiving light from either one side at another side between the excavator tip and a standardized position.
CONSTITUTION: In proportion as a ground improvement machine interpenetrate into the ground a supporting main pipe 9 is bent, a light receiving apparatus 18 fixed with the lower end of the supporting main pipe 9 displaces corresponding to its bending. A projecting apparatus 17 positioned at the upper end is coincided with the standard position and the laser spot 20 of the light receiving apparatus 18 through the vertically downward irraidating laser light is preset in its central position, whereby the spot 20 is displaced from the central position 23 so much as the bent portion of the supporting main pipe 9. A photosensor 19 detects the position of the spot 20 following the displacement of the spot 20 to indicate the displacement from the central position 23 of the spot 20 on the indicator of the marine work ship holding the ground improvement machine 1.
