Abstract

PURPOSE: To rapidly and accurately calculate a distance between measurement points and increase efficiency by measuring an angle of elevation at each measurement point, a crossing angle from the both ends of a base line at a projection point on a level and a crossing angle at one end of a base line from two projection points.
CONSTITUTION: An interlocked arm 4 is installed in a protruded manner in parallel with a horizontal shaft 6 from the vertical axis 8 of a rotary telescopic device 2 and a vertical shaft 15 of a common telescopic device 3 is supported at the end of an interlocked arm 4 in a freely movable manner, so that a distance between the both fulcrums A, B is a base line. In obtaining the distance between measurement points on the surface of a tunnel wall, a crossing angle of the base lines A, B at a projection point on the plane, an angle of elevation at each measurement point and a crossing angle at the one edge of a base line of two projection points are measured, so that the distance between measurement points can rapidly and accurately be calculated by a few number of personnel. Thus it is possible to efficiently measure the relative displacement of the surface of a tunnel wall.
