Description

Technical Field

[0001] The utility model relates to the field of road engineering, in particular to a device for detecting the laying thickness of base material of road engineering. Background Art

[0002] In pavement engineering, the thickness of each layer is closely related to the overall strength of the road. In addition to ensuring strength, strictly controlling the thickness of each structural layer can also play a certain role in controlling the elevation of the road surface, which is a very important indicator. The base layer is the load-bearing layer directly under the surface layer in the pavement structure. The material and construction quality of the base layer are key factors affecting the performance and service life of the road surface.

[0003] A Chinese utility model patent with announcement number CN216620945U discloses a device for detecting the laying thickness of base materials for road engineering projects. The invention inserts a longitudinal rod into the base material to be measured, and measures the laying thickness of the base material to be measured by a ruler on the measuring rod. The reading process requires the measurement personnel to lie down so that the line of sight and the scale line on the ruler are kept horizontal, so as to accurately read the measurement value. The method of reading the laying thickness measurement value of the base material in the above invention is relatively cumbersome and troublesome, and therefore it is urgently needed to be improved.
