Description

Technical Field

[0001] This utility model belongs to the field of highway subgrade technology, and in particular relates to a highway subgrade. Background Technology

[0002] The protection of the roadbed is crucial to ensuring the stability and durability of the highway. Drainage ditches are usually set on both sides of the roadbed, and slopes are set between them to facilitate the flow of water, thereby improving the smoothness of drainage.

[0003] Existing roadbed slopes are generally planted with vegetation to ensure drainage while preventing soil erosion. However, under the scouring of water over a long period of time, the slope will collapse, which will exacerbate the loosening of the soil and reduce the protective effect of the slope, eventually leading to roadbed collapse. To address this, we propose a new type of highway roadbed to solve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a highway subgrade that improves slope protection and ensures subgrade stability, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A highway subgrade includes a subgrade body, the two sides of which are sloping surfaces that slope downwards. A drainage channel with grooves can be poured on the surface of the sloping surface. A pier is poured at the end of the sloping surface. Cobblestones are placed on the top of the pier. Multiple protective plates are provided on the surface of the sloping surface. The multiple protective plates are spliced ​​together. Threaded posts are fixedly connected to the upper and lower positions of the front of the protective plates. A connecting ring is sleeved through the surface of the threaded post for connecting two adjacent protective plates. A fastening nut is threadedly connected to the surface of the threaded post. The end face of the fastening nut is tightly fitted with the connecting ring.

[0006] Preferably, a groove is provided on one side of the protective plate, and an insert is provided on the other side of the protective plate, the insert being engaged with the inner surface of the corresponding groove.

[0007] Preferably, the inner surface of the protective plate has multiple holes, and the inside of the holes is filled with gravel or green plants.

[0008] Preferably, a cone is fixedly connected to the back of the protective plate, the cone is inserted into the interior of the slope, and the cone is a pointed cone design.

[0009] Preferably, the cobblestones can be mixed with cement and fixedly connected to the top of the pier.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a water channel to drain water from the roadbed into a drainage ditch. By setting up piers and cobblestones, the soil on the slope can be reinforced to prevent soil slippage. At the same time, multiple protective plates are laid on the slope to reinforce the slope and prevent soil erosion. By fitting connecting rings onto the surface of threaded columns and fastening them with nuts, adjacent protective plates are reinforced to prevent them from shifting. By setting up the above structure, the slope protection effect is improved and the stability of the roadbed is guaranteed.

[0012] 2. This utility model splices two adjacent protective plates by setting an insert block to be snapped into the corresponding groove;

[0013] 3. By setting holes, the holes can be filled with gravel or planted with greenery, which can further strengthen the stability of the slope and also help with water leakage.

[0014] 4. This utility model uses a cone-shaped insert to penetrate the interior of the slope. The cone is designed with a pointed tip, which makes it easy to insert the protective plate into the slope and secure the protective plate to the surface of the slope. Attached Figure Description
