Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measurement, and more specifically to a tool for measuring the thickness of a road base structure. Background Art
[0002] During the construction of road projects, it is necessary to measure the pavement thickness of the road to ensure the construction quality. The commonly used measurement method is that the surveyor first uses a concrete coring machine to drill holes in the road surface, and then uses a clamp to take out the core sample obtained by drilling. The thickness of the core sample is measured by a measuring ruler to obtain the measurement data of the road surface thickness.
[0003] When workers use a measuring ruler to measure the thickness of a core sample, they usually place the measuring ruler on the core sample and read the data on the measuring ruler. Although this measurement method is simple, the reference of placing the measuring ruler on the core sample cannot be effectively guaranteed, which leads to errors in the measurement data and affects the measurement accuracy.
[0004] Therefore, how to provide a tool for measuring the thickness of a road base structure that has a simple structure, is easy to operate, and has improved measurement accuracy is a problem that technical personnel in this field urgently need to solve. Utility Model Content

The utility model has a simple structure and is easy to operate. When measuring the pavement base structures with different thicknesses, it is only necessary to drive the second connecting rod to move left and right on the beam to a suitable position by sliding, and fasten the slider by fasteners to complete the measurement, thus avoiding the measurement error caused by manual measurement in the prior art and improving the measurement accuracy.
[0009] Preferably, in the above-mentioned pavement base structure thickness measuring tool, the crossbeam is a double-layer beam, including an upper crossbeam and a lower crossbeam, the upper crossbeam and the lower crossbeam are fixed on the side wall of the first connecting rod at intervals, and the lower crossbeam has a scale. The structure is simple and stable.
[0010] Preferably, in the above-mentioned pavement base structure thickness measuring tool, the ends of the upper crossbeam and the lower crossbeam away from the first connecting rod are detachably connected with a U-shaped lever. The detachable connection of the U-shaped lever can facilitate the installation and positioning of the slider, and has a simple and stable structure.
[0011] Preferably, in the above-mentioned pavement base structure thickness measuring tool, the slider is an I-shaped structure, and has an upper slider and a lower slider at both ends, the upper slider and the lower slider are respectively slidably mounted on the outer sides of the upper beam and the lower beam, and the top of the upper slider is fastened to the upper beam by the fastener.
