ABSTRACT:
A system for surveying subterranean hollow spaces arranged on a cable having reinforcing jacketing. The device comprises an oblong tubular housing divided into three sections. A pivot joint connects that top section to the center section and permits rotation of the center section around a longitudinal axis of the surveying system. A tilting joint connects the center section to the bottom section to change the inclination of the bottom section around an orthogonal axis of swivel. There is a rotary drive for rotating the center section and a tilting drive for tilting the bottom section. There is an instrument in the center section for determining the rotary position of the center section. The free end of the bottom section has an exchangeable sensor carrier having a sensor for measuring the hollow space. An angle sensor is located in the bottom section for determining the absolute angle of inclination of the bottom section relative to the perpendicular. This absolute angle determination allows for accurate and precise measurements of the hollow space.
