Description

Technical Field

[0001] The utility model relates to the technical field of subgrade elevation equipment, in particular to a calibration device for road subgrade elevation. Background Technique

[0002] The Chinese patent document with the publication number of CN212834901U discloses a elevation control bracket for subgrade and pavement, which proposes that at present, in the construction of subgrade and pavement structural layers, the common method for controlling the construction elevation of traditional subgrade and pavement structural layers is to hang steel wires with steel pins, but this method has many deficiencies. For example, the embedding of steel pins damages the road surface; the steel wire has a large deflection; during the process of being used in conjunction with a paver, the steel pins form an obstacle to the contact sensor of the paver; the steel wire and the steel pin are tied, and it is easy to slip during the tensioning process of the steel wire; the paving thickness and elevation need to be measured manually with a ruler, which is easy to cause errors, etc. The existing road surface elevation methods have many inconveniences, are not convenient to operate, and have low elevation accuracy. Therefore, an elevation control bracket for subgrade and pavement is needed to improve the above problems.

[0003] In the above scheme, the dust at the construction site is relatively large, which is easy to adhere between the guide rod and the guide sleeve, affecting the up and down movement of the cooperation between the two. Long-term friction will cause it to be unable to maintain horizontal, affecting the construction quality.

[0004] Therefore, the utility model proposes a calibration device for road subgrade elevation to solve the above problems. Content of the Utility Model
