A plurality of groups of fourth bolts 22 are arranged at equal intervals at the top ends of the connecting frames 1. And the fourth bolts 22 all extend to the outside of the connecting frames 1;

[0026] During use, place the connecting frame 1 at the top of the highway bridge slope. By operating the rotation of the outer protection plate 4, the second movable sleeve 5 is driven to rotate. Supported by the first movable sleeve 3 and the movable shaft 2, the second movable sleeve 5 rotates on the surface of the movable shaft 2. The second movable sleeve 5 drives the outer protection plate 4 to rotate and adjust. By operating the rotation of the fourth movable sleeve 12, supported by the third movable sleeve 11 and the second connecting seat 17, the fourth movable sleeve 12 drives another group of outer protection plates 4 to rotate, so as to conveniently adjust the inclination angles of multiple groups of outer protection plates 4 and the highway bridge slope. By rotating the first bolt 6, the first bolt 6 extends through the outer protection plate 4 into the interior of the highway bridge slope. Multiple groups of first bolts 6 fix the outer protection plate 4 on the surface of the highway bridge slope to cover and protect the highway bridge slope. By operating the sliding of the sleeve 14 on the surface of the support shaft 13, the distance between the two sleeves 14 is adjusted. The two sleeves 14 drive the outer protection plate 4 to move, so as to conveniently adjust the distance between the two connecting frames 1. After the adjustment is completed, by rotating the third bolt 15, the third bolt 15 extends through the sleeve 14 to the surface of the support shaft 13, so that the third bolt 15 fixes the sleeve 14 and the support shaft 13, and conveniently fixes the two connecting frames 1 together.

Second bolts 9 are arranged on the surface of the protection disc 7 on one side of the rotating disc 8, and the second bolts 9 all extend through the protection disc 7 to the surface of the rotating disc 8;

[0028] During use, by operating and turning the second bolt 9, the rotating disk 8 is fixed inside the protective disk 7 by the second bolt 9. When it rains, the rotating disk 8 and the protective disk 7 protect the highway bridge slope, preventing rainwater from scouring the slope soil. At the same time, multiple water channels 18 inside the outer protective plate 4 drain the rainwater. The rainwater on the surface of the protective disk 7 flows into the multiple connecting grooves 20, and the drain holes 23 drain the rainwater inside the connecting grooves 20. When it is necessary to open the rotating disk 8 for planting vegetation on the slope surface inside the protective disk 7 to reinforce the slope protection, by operating and reversely turning the second bolt 9, the second bolt 9 changes from the tightened state to the loosened state. Under the sliding support of the rotating disk 8 and the annular sliding groove 21, the rotating disk 8 slides inside the protective disk 7 to facilitate the rotating disk 8 to enter the inside of the protective disk 7 for vegetation planting. It realizes the convenient sliding protection of the protection structure, avoids soil and water loss on the slope caused by rainwater scouring, facilitates the processing of the protection structure for vegetation planting, and improves the firmness of the protection of the protection structure.

[0029] Working principle: When in use, first place the connecting frame 1 at the top of the highway bridge slope. By operating the rotation of the outer protection plate 4, the second movable sleeve 5 is driven to rotate. The second movable sleeve 5 rotates on the surface of the movable shaft 2, and the outer protection plate 4 is driven by the second movable sleeve 5 to rotate and adjust. By operating the rotation of the fourth movable sleeve 12, the fourth movable sleeve 12 drives another group of outer protection plates 4 to rotate, so as to conveniently adjust the inclination angles of multiple groups of outer protection plates 4 and the highway bridge slope. The first bolt 6 extends through the outer protection plate 4 into the interior of the highway bridge slope, and multiple groups of first bolts 6 fix the outer protection plate 4 on the surface of the highway bridge slope to cover and protect the highway bridge slope. By operating the sliding of the bushing 14 on the surface of the support shaft 13, the distance between the two bushings 14 is adjusted. The two bushings 14 drive the outer protection plate 4 to move, so as to conveniently adjust the distance between the two connecting frames 1. After the adjustment is completed, the third bolt 15 extends through the bushing 14 to the surface of the support shaft 13, so that the third bolt 15 fixes the bushing 14 and the support shaft 13, so as to conveniently fix the two connecting frames 1 together. The fourth bolt 22 extends through the connecting frame 1 into the interior of the highway bridge slope, so as to conveniently fix the connecting frame 1 by the fourth bolt 22. The second bolt 9 fixes the rotating disk 8 inside the protection disk 7. When it rains, the rotating disk 8 and the protection disk 7 protect the highway bridge slope, preventing rainwater from scouring the slope soil. At the same time, multiple water channels 18 inside the outer protection plate 4 drain the rainwater. The rainwater on the surface of the protection disk 7 flows into the multiple connecting grooves 20, and the drain holes 23 drain the rainwater inside the connecting grooves 20. When it is necessary to open the rotating disk 8 to plant vegetation on the slope surface inside the protection disk 7 to reinforce the slope protection, by operating the reverse rotation of the second bolt 9, the second bolt 9 changes from the tightened state to the loosened state. Under the sliding support of the rotating disk 8 and the annular chute 21, the rotating disk 8 slides inside the protection disk 7, so as to conveniently make the rotating disk 8 enter the interior of the protection disk 7 for vegetation planting, and complete the use of the protection structure.
