A device for measuring the thickness of a road asphalt spread

Abstract

This utility model discloses a road asphalt paving thickness measuring device, comprising an upper rod, at least one middle rod, and a lower rod. The top end of the middle rod is detachably and fixedly connected to the bottom end of the upper rod, and the bottom end of the middle rod is detachably and fixedly connected to the bottom end of the lower rod. The upper, middle, and lower rods are coaxially arranged. A positioning sleeve that can slide along its axial direction is fitted on the lower rod. The inner diameter of the positioning sleeve is adapted to the outer diameter of the lower rod. A bolt hole is formed on the circumferential side wall of the positioning sleeve along its radial direction, and a tightening bolt is threaded into the bolt hole. This utility model has the advantages of allowing the measuring rod length to be adjusted according to actual operating needs to adapt to different measuring heights, avoiding burns from high-temperature asphalt due to excessively close distance or bending over during measurement, being flexible and convenient to use, having a simple structure of the measuring rod, and being easy to adjust in length.
