Thickness detector for highway engineering supervision

The utility model discloses a thickness detector for highway engineering supervision, which comprises a bottom plate, four uniformly distributed measuring rods are arranged on the edge of the upper surface of the bottom plate, the measuring rods comprise three fixed rods and a movable rod, the bottom of the movable rod is rotatably connected with the bottom plate up and down, and the bottom of the movable rod is rotatably connected with the bottom plate up and down. The measuring rod is slidably sleeved with a partition plate used for separating samples. According to the thickness detector for highway engineering supervision, a core sample can be inversely placed in the detector, so that the four measuring rods can be tightly attached to the core sample for measurement, measurement errors caused by inclination between the measuring rods and the core sample can be avoided, and meanwhile, the four measuring points can be uniformly distributed, so that the measurement precision is improved; and a plurality of co
