Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a road construction measuring device. Background Art

[0002] With the continuous development of society, the highway industry has also developed rapidly. During the construction of asphalt pavement, the paving of asphalt is one of the very important components. It has the advantages of good strength and not being prone to shrinkage cracks. It is one of the main paving methods in existing highway construction. The thickness of each layer is closely related to the overall strength of the road. In pavement design, whether it is a rigid pavement or a flexible pavement, what ultimately needs to be determined is the thickness of each layer. Only when the thickness is ensured can the strength of each layer and the overall pavement be guaranteed. The quality of the highway depends to a large extent on the paving of the asphalt road, and the paving of the asphalt road mainly involves controlling the paving thickness.

A rotating shaft is rotatably installed inside the vertical plate. One end of the rotating shaft is fixedly installed with a cam. The outer bottom of the cam is movably abutted against a moving plate. The bottom of the moving plate is fixedly installed with a moving rod. The tops of both sides of the bottom of the moving plate are fixedly installed with springs, and the bottoms of the springs are fixedly installed on the top of the frame.
