Description

Technical Field

[0001] The utility model relates to the technical field of highway roadbed filling construction equipment, in particular to a roadbed filling layer thickness control device. Background Art

[0002] The earth and stone embankment must be filled and compacted in layers according to the designed section. Filling according to the specified layer thickness can obtain uniform compaction. With the rapid development of the economy and transportation industry, the roadbed filling construction technology plays a vital role in the quality of highway construction. During the filling construction of the highway roadbed earth and stone engineering, the filling must be carried out according to the layer thickness determined by the test section to ensure that each layer achieves the compaction effect and reduce the post-construction settlement.

[0003] The existing announcement number is CN218786748U, and the name is a roadbed filling layered thickness plate, which includes a bracket and a thickness plate arranged on the bracket. The bracket includes a transverse rod, a longitudinal rod and an oblique rod. There are two transverse rods and two oblique rods respectively. One end of the transverse rod is connected to the back bottom of the thickness plate, one end of the oblique rod is connected to the back top of the thickness plate, and the other end of the transverse rod is connected to the other end of the oblique rod. The longitudinal rod connects the connecting ends of the transverse rod and the oblique rod. Marking paper is affixed to the thickness plate. The utility model of the roadbed filling layered thickness plate can control the filling thickness more accurately. The roadbed layered thickness plate simulates the actual layer relative position through different colors and marks the corresponding layer thickness, which is beneficial to the determination of the roadbed filling construction process and the control of the layer thickness, and ensures the strength and stability of the roadbed. The roadbed filling layered thickness plate has good stability and is convenient for assembly and disassembly.

[0004] However, the above-mentioned method of indicating the thickness of the roadbed filling uses the marking paper posted on the thickness plate to indicate the thickness of different roadbed layers. However, this indication method requires human vision to observe the thickness control line on the marking paper to control the thickness of the road layer filling. However, since human vision cannot remain completely parallel to the thickness control line on the marking paper, errors occur in the observation of the roadbed filling, which affects the accuracy of the roadbed filling thickness.
