Measuring device for geotechnical engineering

The measuring device comprises a rotating rod, an installation box and a length adjusting assembly, the length adjusting assembly comprises a sliding rod and a supporting block, one end of the rotating rod is rotationally connected with the installation box, the other end of the rotating rod is fixedly provided with a cylindrical spirit bubble, the installation box is provided with a sliding through hole, and the sliding through hole is communicated with the supporting block. The sliding rods are mounted on the inner sides of the sliding through holes, supporting blocks are fixedly arranged at the ends, away from the mounting box, of the sliding rods, and anti-skid rubber pads are arranged at the bottom ends of the supporting blocks. The device has the beneficial effects that the mechanical structure is simple, the device can still be normally used in rainy days or underwater, the application range of the device is widened, the length of the device can be adjusted by pulling out the sliding rod, and the accur
