摘要
PROBLEM TO BE SOLVED: To provide an automatically measuring system for a tunnel section that can safely and accurately measure a tunnel section by remote control.;SOLUTION: A three-dimensional section measuring instrument body 10 with an automatic section measurement function is mounted on a movement carriage 20 with a free unmanned drive by the remote control by wireless or wire induction through an automatic level adjusting mechanism 30, and a shape of the tunnel section is automatically measured by a remote control from a total station 40 placed outside the tunnel. A position detecting target 12 and a scale plate 13 for swivel angle detection are installed on the three-dimensional section measuring instrument body 10, and a position detecting target 11 and the scale plate 13 for the swivel angle detection are collimated by the total station 40 under horizontal leveling at an arbitraty stop position of the movement carriage 20. Then a direction angle α' and a swivel angle θ are calculated and a position and a direction of the three-dimensional section measuring instrument body 10 are determined by these direction angle α' and swivel angle θ.;COPYRIGHT: (C)2002,JPO
