Document Type and Number:
Japanese Patent JP7231531
Kind Code:
B2
Abstract:
To propose a steel support construction method that makes it possible to easily build a steel support in a predetermined position.SOLUTION: The present invention comprises: a machine installation step S2 for installing an erector machine in a predetermined position in a tunnel; an irradiator adjustment step S3 for adjusting the orientation of a circumferential laser irradiator attached to a boom of the erector machine; an irradiator arrangement step S4 in which the circumferential laser irradiator is arranged at a predetermined position; and a support building step S5 for building steel support by operating an erector of the erector machine. In the support building step S5, a work of irradiating the steel support site with the circumferential laser with the circumferential laser irradiator, a work of irradiating the position that will be a leg of the steel support with the laser beam, a work of building the steel support are carried out while confirming the position in the longitudinal direction with the circumferential laser and confirming the position in the transverse direction with the laser beam.SELECTED DRAWING: Figure 3
