DEVICE FOR DETERMINATION OF ANGULAR POSITION OF TUNNEL SHIELD Russian patent published in 1995 - IPC

Abstract RU 2034144 C1

FIELD: underground construction. SUBSTANCE: angular position transducer is made in form of three laser geros whose axes are mutually orthogonal and one axis is parallel to axis of tunnel shield. Outputs of laser gyros are connected with inputs of reversible counters whose outputs are connected with inputs of computer by means of which deviation of tunnel shield from preset direction is determined by three coordinate axes. EFFECT: higher efficiency. 2 cl, 2 dwg
