AUTOMATIC MEASUREMENTS OF TUNNELLED PROFILES

An automatic instrument designed for the economic measurement of the profiles or cross sections of underground constructions, such as galleries, caverns and tunnels has been developed by Amberg Measuring Technique. The AMT Profil, mounted on a tripod, is connected with a programmable desk computer, which controls the functions of the profile measuring instrument and records and transmits the measured profile shape onto the screen. The measuring principle is based on an optical-electonic system using the triangular function with a fixed base and measured angle.
