Title:
LOCATING METHOD AND SYSTEM OF BORING ROD, PROGRAM FOR DRILLING LOCUS ANALYSIS OF BORING ROD, AND STORAGE MEDIUM
Document Type and Number:
Japanese Patent JP2005156369
Kind Code:
A
Abstract:
To improve the locating accuracy of a boring rod drilling the ground, in a universal drilling method for drilling the ground linearly or curvedly.
The flexible boring rod 10 has an optical fiber sensor 5a flexible with its flexure deformation. A drilling locus of the boring rod 10 flexibly deformed at the ground drilling time is detected on the basis of the distortion quantity measured by a change of a physical value of light passing the optical fiber sensor 5a. The detected drilling locus is visualized on a display device by two-dimensional or three-dimensional display.
