[0002] The water-stabilizing layer is the abbreviation of cement-stabilized gravel layer, which is the main load-bearing layer of the entire road structure. During the paving process of the water-stabilizing layer, the paving elevation needs to be measured and located. The elevation refers to the distance from a certain point to the base surface along the plumb line. Through elevation positioning, the paving height and flatness of the water-stabilizing layer can be guaranteed to meet the standards.

[0003] Based on the above, the inventors found that the existing elevation positioning device is mainly composed of a reference rod in the vertical direction and an identification rod in the horizontal direction. The identification rod and the reference rod are vertically arranged and slidably connected, but the angle of the identification rod is inconvenient to adjust and store, and it occupies a large space during transportation or storage, affecting the use effect of the positioning device. Therefore, in view of this, the existing structure is studied and improved, and an elevation positioning device for the paving stage of a water-stabilizing layer is provided, in order to achieve a more practical purpose.
