Description

Technical Field

[0001] This utility model relates to the field of roadbed protection, specifically to a highway roadbed protection structure. Background Technology

[0002] The soil of a highway subgrade must be compacted and stabilized to provide safety for vehicles and pedestrians traveling on the highway.

[0003] Especially on highways built on hillsides, there are upward or downward slopes and cliffs on both sides of the road. The soil on the slope is prone to landslides, which can damage the road surface or cause the road to collapse. Generally, cement grids are laid continuously on the slope to form a base frame for soil stabilization.

[0004] However, cement grids are ultimately a simple paving structure. When the force on the top of the slope is too great, the cement base frame will also break. The damaged cement base frame loses its effective soil stabilization function, and the highway will still face safety risks. Therefore, a highway subgrade protection structure is provided. Utility Model Content

[0005] The technical problem this invention aims to solve is that the soil-stabilizing cement frame laid on the sloping soil of the roadbed is damaged when subjected to excessive pressure, and cannot effectively assume the responsibility of protecting the road.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a highway subgrade protection structure, comprising:

[0007] The system employs a circular cement base and a square cement support. The support has arc-shaped cement plates on both sides that fit the outer contour of the base. The base and support are arranged at intervals on the roadbed slope to provide solid protection.

[0008] The base is provided with brackets at the top and bottom, and a rubber column that can bear pressure and provide cushioning is connected between the brackets. A telescopic cylinder located outside the rubber column is also connected between the brackets to provide a limiting function for the rubber column.

[0009] Connecting blocks are installed around the base, and guide rods are rotatably connected between adjacent sides of the connecting blocks.

[0010] The base is connected to a carrier frame on its rear side, and the carrier frame is connected to a plurality of triangular protruding locking blocks on its rear side. The locking blocks are continuously arranged on the rear side of the carrier frame and are embedded in the soil after the base is buried on the roadbed slope, where they lock into each other.

[0011] Furthermore, the bases are installed on the roadbed slope in an interlaced manner, and the center line connecting three adjacent circular bases together forms an equilateral triangle structure.

[0012] Furthermore, the support is internally connected to multiple support plates, and its interior is divided into multiple triangular structures by the support plates. Multiple support rods are connected between the support and the support plate, and a rubber pad is installed on the outside of the support plate.

[0013] Furthermore, the telescopic cylinder includes a slide cylinder with multiple grooves installed on the outside of the rubber column, and a bracket is connected to multiple slide rods with ends embedded in the grooves of the slide cylinder and in a sliding connection with them.

[0014] Furthermore, the front edge of the base is connected to an inwardly bent baffle.

[0015] The advantages of this invention compared to existing technologies are as follows: This device improves upon the common structure of cement-based soil stabilization frames. First, it uses a circular base as the main body, and arranges three adjacent bases at three points of an equilateral triangle in an alternating manner, with supports connecting each adjacent base. Second, multiple inclined guide rods are installed inside the base to distribute the force transmitted from above to both sides and cancel it out between adjacent bases, greatly reducing the destructive force borne by the cement-based frame and indirectly improving its bearing capacity, thus providing a higher-strength soil stabilization effect for highway subgrades.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a highway subgrade protection structure, combined with attached... Figure 1 and attached Figure 9 It includes: a circular cement base 1 and a square cement support 9. The support 9 is connected to two sides with an arc-shaped cement plate 10 that fits the outer contour of the base 1. The base 1 and the support 9 are arranged at intervals on the roadbed slope to provide solid protection.

[0028] On both sides of the road, whether uphill or downhill, grids made mainly of cement are installed to stabilize the soil on the slope, preventing soil from sliding down the upper slope and damaging the road surface and vehicles, and preventing soil from collapsing on the lower slope, causing road surface cracks and collapses, thus providing protection for the roadbed.

[0029] The cement grid in the device has a circular structure. In addition, there are square cement grids, namely the support 9 parts, connected between the circular bases 1. They are in contact with each other and form a net on the earthen slope.

[0030] The base 1, support 9, and components such as the frame 13, locking block 14, and pallet 10 mentioned below are all made of cement or reinforced concrete, while the guide rod 3, bracket 4, and other parts can be made of metal.

[0031] The bases 1 are installed alternately on the roadbed slope, and the center line connecting any three adjacent circular bases 1 forms an equilateral triangle structure. Figure 6-7The support 9 is internally connected to multiple support plates, and its interior is divided into multiple triangular structures by the support plates. Multiple support rods 11 are connected between the support 9 and the support plate 10. A rubber pad 12 is installed on the outside of the support plate 10.

[0032] From a distance, the bases 1 laid on the earthen slope from top to bottom are staggered. That is, below the base 1 at the top layer, two bases 1 are arranged symmetrically with respect to each other above the center line of the base 1 above. In the narrowest space between the circular bases 1, a support 9 with arc-shaped support plates 10 at both ends is installed. The support 9 is installed on the earthen slope, but the support plates 10 at both ends are in close contact with the outer surface of the bases 1 on both sides. Three adjacent bases 1 and supports 9 can be regarded as a group. They together form a relatively stable triangle. Each base 1 can also be combined with the bases 1 adjacent to it in other directions to form a group. They extend on the earthen slope in this laying form, providing a relatively high-strength support foundation for the roadbed.

[0033] Combined with appendix Figure 2-5 and attached Figure 8 The base 1 has brackets 4 connected inward at both the top and bottom. The brackets 4 are connected together to a rubber column 5 that can bear pressure and provide cushioning. The brackets 4 are also connected together to a telescopic cylinder located outside the rubber column 5 to provide a limiting function for the rubber column 5. The telescopic cylinder includes a slide cylinder 6 installed on the outside of the rubber column 5 with multiple sliding grooves. The brackets 4 are connected to multiple slide rods 7 whose ends are embedded in the sliding grooves of the slide cylinder 6 and are slidably connected to it.

[0034] Since the force on the roadbed and the cement grid on the roadbed generally comes from above, a rubber column 5 with a force buffering effect is vertically installed inside the base 1 to reduce the pressure on the base 1 and the roadbed. A telescopic cylinder is installed not far from the outside of the rubber column 5 to prevent the rubber column 5 from bending itself after being subjected to excessive force.

[0035] Connecting blocks 2 are installed around the base 1. Guide rods 3 are rotatably connected between adjacent sides of the connecting blocks 2. An inwardly bent baffle 8 is connected to the front edge of the base 1.

[0036] The guide rod 3 is arranged in an inclined state inside the base 1, and both ends of it are rotatably connected to the base 1. When the top of the base 1 is subjected to pressure along with the roadbed, the guide rod 3 itself will not actually move because the base 1 itself is structurally rigid and fixed. However, the ends of the guide rod 3 located at the upper and lower ends of the base 1 will still have a tendency to move towards the center of the base 1. This causes the other ends of the guide rod 3 located at the left and right ends of the base 1 to have a tendency to move outward from the base 1. The tendency is the process of force transmission, and the direction of movement under this tendency is the direction of force transmission.

[0037] The force originally propagated from top to bottom, but after passing through the guide rod 3, it was changed to propagate to both sides. This part of the force propagated laterally was first buffered and partially dissipated by the rubber pads 12 on the support plates 10 on both sides of the support 9.

[0038] When two adjacent bases 1 on the same floor are both under pressure from above, since each base 1 has the same specifications and structure, they will eventually have roughly equal amounts of force transmitted outward to one side of the base 1. On the side where adjacent bases 1 are close to each other, the roughly equal amounts of force are transmitted in completely opposite directions. When they reach the support 9, they almost cancel each other out and then disappear. This reduces the force borne by the base 1 and the roadbed, providing them with better protection.

[0039] The base 1 is connected to a carrier frame 13 on the rear side. The carrier frame 13 is connected to a plurality of triangular protruding locking blocks 14 on the rear side. The locking blocks 14 are continuously arranged on the rear side of the carrier frame 13 and are embedded in the soil after the base 1 is buried on the roadbed slope, where they lock into each other.

[0040] The protruding locking block 14 on the rear side of the carrier 13 has an isosceles triangular structure. Since the cement grid assembly is generally inclined to the ground after being installed on the roadbed slope, the locking block 14 embedded in the soil is like a continuous staircase structure. Except when the soil fracture in the roadbed is very deep, when the slope fractures relatively close to the surface, or when the base 1 loosens downward due to poor soil stability, one side of the locking block 14 can always be firmly locked in the soil. That is, the soil prevents the locking block 14 from moving, providing a more reliable connection and stability for the base 1 and the roadbed.

[0041] In a specific implementation of this utility model, the base 1 in the component is installed on the roadbed soil stabilization layer in an interlaced manner, and the support 9 is arranged between the base 1. The three adjacent bases 1 together form an equilateral triangle structure, which not only provides a good soil stabilization effect for the roadbed, but also improves its own stability and makes it less likely to be damaged.

[0042] When the roadbed is subjected to pressure, the force propagating downward on the base 1 is first buffered by the rubber column 5 installed inside the base 1. Under the tendency of the guide rod 3 to rotate, part of the force is guided to propagate to both sides. When it touches the force propagated from the adjacent base 1 on the left and right, it cancels out and resolves the force, which greatly reduces the pressure borne by the base 1 and the roadbed as a whole, thereby indirectly improving its own load-bearing capacity.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
