Abstract

PURPOSE:To shorten a machine setting time by computing a track with a computer regardless of the position of a machine main-body, and by controlling a concrete mold automatically. CONSTITUTION:When a machine main-body is set at a point P shifted positionally from the center of a tunnel, then the track of a main swing angle theta1, a mold tilt angle theta2, and a boom length L1 is computed by a computer 15. In the meantime, the swing angle theta1 of a main boom is measured by a rotary encoder 11. After that, via a hydraulic valve controller 1, a main-boom-telescopic jack 3 and a mold inclination regulating jack 4 are controlled by a linear encoder 12. Then, this working is repeated by swinging the main boom 6 with a swing actuator 5, and a mold is moved along a tunnel designing cross-sectional area D. As a result, a machine setting time can be shortened, and the creating precision of lining concrete can be improved.
