<P>PROBLEM TO BE SOLVED: To provide a method for smoothly guiding a support to a prescribed position and improving position accuracy of support building-up while improving work efficiency of the support building-up. <P>SOLUTION: A tunnel support guiding and building method is for holding supports 4L and 4R by a holding part of an erector device 1, guiding them to the vicinity of a face 5 of a tunnel and building them. Erector targets E1 and E2 are attached to the holding part of the erector device 1, support targets S1-S4 are attached to upper ends and lower ends of the supports 4L and 4R, positions of the erector targets E1 and E2 are measured, the erector device 1 is controlled on the basis of the positions of the erector targets E1 and E2, and the supports 4L and 4R are guided to the vicinity of the face 5. Then, positions of the support targets S1-S4 are measured, the erector device 1 is controlled on the basis of the positions of the support targets S1-S4 at the upper ends or lower ends of the supports 4L and 4R, and the supports 4L and 4R are guided to design positions and built up. <P>COPYRIGHT: (C)2013,JPO&INPIT |
