Multi-span rigid framework cantilever linear control measuring device

The utility model discloses a multi-span rigid framework cantilever linear control measuring device. The multi-span rigid framework cantilever linear control measuring device is characterized by comprising a level gauge, wherein the level gauge is fixedly arranged above a main pier block through a triangular mounting bracket, the triangular mounting bracket is fixedly installed in the middle of the upper end face of the main pier block, rulers are fixedly installed on hanging basket beam frames at the two ends of the main pier block respectively, and the upper end faces of the rulers are on the same horizontal plane as the level gauge. According to the multi-span rigid framework cantilever linear control measuring device, it is not needed that people stand at the fronts ends of hanging baskets to hold the rulers in the observation process, as a result, measuring error sources and security risks are reduced, accidental errors caused by different erection positions of the rulers during two measuring processes a
