| description | The invention belongs to the technical field of tunnel construction, and provides an instrument and method for detecting the perpendicularity of a tunnel steel arch. The supporting seat is arranged above the base; the supporting seat is in threaded connection with a plurality of leveling foot screws in the circumferential direction, and the bottoms of the leveling foot screws are pressed on the upper surface of the supporting seat; the rotating table is rotatably connected to the upper part of the supporting seat; a second circular level is arranged on the upper surface of the rotating table; the two groups of lateral laser transmitters are symmetrically arranged on the side wall of the rotating table; the graduated scale is fixedly arranged at the top of the rotating table and is transversely arranged; the graduated scale is slidably connected with a sliding seat along the length direction; the graduated scale is perpendicular to the lateral laser transmitter; the first distance measuring instrument is fixed |
