As shown in fig. 1, 3 and 4, the first direction X of the panels 300 is fixed by the embedded structures 200, and each panel 300 corresponds to a plurality of embedded structures 200 arranged at intervals along the second direction Y. The first direction X is perpendicular to the second direction Y.

Specifically, each embedded structure 200 includes an embedded plate 210 and a hoop structure 250.

The embedded portion 213 and the exposed portion 211 are integrally formed, the embedded portion 213 extends parallel to the first direction X and the second direction Y, and the exposed portion 211 is located on one surface of the embedded portion 213 along the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. On a projection plane perpendicular to the third direction Z, a projection of the exposed portion 211 is located within a projection of the embedded portion 213. The embedded portion 213 thus forms a positioning area toward the exposed portion 211. After the concrete is cured and formed, the concrete contacts the positioning area and limits the embedded part 213 from separating from the concrete layer 130 along the third direction Z.

In fixing the prefabricated panel 251 and the exposed portion 211 by the fixing bolts 253, the fixing bolts 255 may be first placed on the exposed portion 211 and then the threaded rods 2553 are passed through the mounting holes of the prefabricated panel 251. After the precast slab 251 and the pre-buried slab 210 are fixedly connected. The bolt head is clamped between the embedded plate 210 and the precast plate 251, so that the bolt head has better stability.

For example, the portion close to the concrete layer 130 is made of steel material, which facilitates the fixing of the panel 300 and the snap spring 257 and receives the elastic force of the snap spring 257. And the part far away from the concrete layer 130 is made of fiber plastic, thereby reducing the production cost and the weight of the panel 300.

When an earthquake occurs, the bearing capacity of the pre-embedded plate 210 can be reduced, and the impact of scouring and rock fall can be matched when the earthquake occurs, so that the influence of the natural environment on the connection strength of the pre-embedded plate 210 and the panel 300 is reduced, and the slope structure of the earthquake-prone area is not easy to slip. The panel 300 belongs to a structure requiring regular maintenance, and the panel 300 connected by the hoop structure 250 is easy to detach and mount, so that the workload of worker maintenance is reduced, and the maintenance cost is also reduced.

As shown in fig. 5, 6, and 7, in the present embodiment, the first curved section 2571 is substantially C-shaped, the second curved section 2573 is also substantially C-shaped, and the first curved section 2571 and the second curved section 2573 are juxtaposed in the second direction Y. The first bent section 2571 extends away from the prefabricated panel 251 from a position near the panel 300 to a position near the nut 2555. The second bent section 2573 extends away from the prefabricated panel 251 from a position near the panel 300 to a position near the nut 2555. The portion of the first bending section 2571 away from the prefabricated panel 251 and the portion of the second bending section 2573 away from the prefabricated panel 251 are continuous such that the portion of the snap spring 257 where the first bending section 2571 and the second bending section 2573 are coupled is tilted in a direction away from the prefabricated panel 251.

In the anti-slip mechanism for a roadbed slope, the first bending section 2571 and the second bending section 2573 extend away from the precast slab 251, so that the fixing bolt 255 presses the tilting position of the first bending section 2571 and the second bending section 2573 in the clamping spring 257, and the parts of the first bending section 2571 and the second bending section 2573 between the fixing bolt 255 and the panel 300 are deformed to apply elastic pressure to the panel 300, wherein the elastic pressure is convenient for responding to the stress caused by an earthquake.

In this embodiment, a drainage groove 2511 is formed on the prefabricated panel 251, and the panel 300 is connected to the prefabricated panel 251 such that a drainage hole is formed in the drainage groove 2511.

Snap springs 257 act on first portion 311, and correspondingly, if panel 300 is made of a composite material, the steel material forms first portion 311 and the plastic material forms second portion 313. The steel material is able to withstand greater pressures and is less likely to damage when the snap spring 257 exerts a pressure on the first portion 311.

The highway subgrade slope anti-skid mechanism introduces the inner hexagonal rod through the installation notch 330, and the nut 2555 is sleeved on the inner hexagonal rod, so that the nut 2555 is convenient to disassemble and assemble. When the stabilizing bolt 255 needs to be detached, the end of the inner hexagonal rod with the inner hexagonal hole extends into the arc-shaped groove, the nut 2555 of the stabilizing bolt 255 is sleeved into the inner hexagonal hole, and then the other end of the inner hexagonal rod is rotated, so that the inner hexagonal rod is rotated to drive the nut 2555 to rotate. The longer arm of force can be installed to the one end that the allen bar lies in outside the arc groove, and the arm of force perpendicular to third direction Z extends, can be convenient for the application of force through the longer arm of force and rotate in order to drive nut 2555.
