Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a roadbed construction thickness control device. Background Technology

[0002] In road construction, the subgrade, as the foundation structure of the pavement, directly affects the overall stability and service life of the road. Subgrade thickness is one of the key control indicators for ensuring its bearing capacity, strength, and durability. Accurately controlling the subgrade thickness can effectively prevent early pavement damage due to insufficient thickness, or material waste and construction delays due to excessive thickness. Therefore, precise control of thickness is of great significance during subgrade construction. With the continuous development of the road construction industry, various subgrade thickness control devices have emerged. These devices, through different principles and structural designs, provide construction personnel with certain thickness references and control methods, thereby improving the standardization of subgrade construction to a certain extent.

[0003] However, existing roadbed thickness control devices present many inconveniences in actual operation. On the one hand, some devices have complex structures, and the installation and debugging process is cumbersome, requiring professionals to spend a lot of time on preliminary preparations, which not only affects construction efficiency but may also lead to a decrease in control accuracy due to improper operation. On the other hand, many control devices have poor adjustment flexibility. When the geological conditions, roadbed materials, or design thickness of the construction section change, it is difficult to quickly adjust the corresponding parameters and cannot adapt well to diverse construction needs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a roadbed construction thickness control device, including a protective plate for protecting both sides of the roadbed, a through groove is provided on the protective plate, an outer sleeve is installed in the through groove, a support edge is fixedly provided on the outer wall of the top of the outer sleeve, a roller is rotatably installed on the support edge, a support rod is installed inside the outer sleeve, and a reference plate is installed between the two support rods.

[0008] Furthermore, the support rod is slidably connected to the outer casing.

[0009] Furthermore, a lead screw is rotatably mounted on the outer casing, and the lead screw is connected to the support rod by a thread. Rotating the lead screw adjusts the height of the support rod.

[0010] Furthermore, a screw-turning block for rotating the screw is fixedly installed on the lead screw.

[0011] Furthermore, the outer wall of the support rod is marked with graduations.

[0012] Furthermore, mounting holes are provided at the bottom of the protective plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a roadbed construction thickness control device, which has the following beneficial effects:

[0015] This new roadbed construction thickness control device features an outer sleeve with support rails and rollers installed in the through grooves of the side guard plates of the roadbed. Combined with support rods that can be installed within the outer sleeve and a reference plate between the two support rods, the device provides a clear and intuitive reference for roadbed construction thickness, enabling precise control. Furthermore, the combination of the outer sleeve and support rods facilitates quick installation and adjustment. The rollers enhance the overall portability of the device, and the height of the reference plate can be flexibly adjusted to accommodate different thickness requirements. This effectively solves the problems of cumbersome operation, poor adjustment flexibility, and insufficient portability of existing devices, significantly improving roadbed construction efficiency and thickness control accuracy.
