Embodiment
[0018] Please refer to Figures 1-4 , a composite retaining structure for high fill and deep cut roadbeds on slopes of the present utility model: including a base 1, a convex block 2 is integrally formed on the outer side of the base 1, a rotating shaft 3 is rotatably connected to the inner side of the convex block 2, a guard plate 4 is fixedly connected to the outer side of the rotating shaft 3, a first bolt 5 is threadedly penetrated through the top of the guard plate 4, a first installation mechanism 6 is arranged at one end of the guard plate 4, and the first installation mechanism 6 includes a support plate 601, a first insertion block 602, a first pin hole 603, a first slot 604, a fixing groove 605 and a second bolt 606. A support plate 601 is arranged at the top of one end of the guard plate 4, a first insertion block 602 is fixedly connected to the bottom of the support plate 601, a first pin hole 603 is opened on the outer side of the first insertion block 602, a first slot 604 is opened on the top of the guard plate 4, a fixing groove 605 is opened on one side of the guard plate 4, and a second bolt 606 is threadedly connected to the inner side of the fixing groove 605. A second installation mechanism 7 is arranged on the top of the base 1. When in use, after the base 1 is fixed, then the guard plate 4 is hinged and attached to the slope. Then, the first bolt 5 is threadedly penetrated through the top of the guard plate 4 and screwed into the rock layer of the slope to fix the guard plate 4. The slope is supported by the guard plate 4. The setting that the guard plate 4 is hinged to the base 1 through the rotating shaft 3 can improve the adaptability to slopes of different steepness. When falling rocks occur, the support plate 601 can play a certain role in blocking and slowing down the falling speed of the falling rocks. The guard plate 4 fits the steep slope, so that the support plate 601 is inclined, which can better block the falling of the falling rocks.
[0019] Furthermore, the outer wall of the first insertion block 602 is adapted to the inner wall of the first slot 604, and the first insertion block 602 is fixedly connected to the guard plate 4 through the second bolt 606.
[0020] Furthermore, the guard plate 4 is hinged to the base 1 through the rotating shaft 3.
[0021] For better protection, the second installation mechanism 7 includes a third bolt 701, a second slot 702, a second plug 703, a second pin hole 704, a baffle 705, a chute 706, a sliding plate 707, a rubber plate 708 and a top plate 709. The outside of the base 1 is threadedly connected with the third bolt 701. A second slot 702 is opened at the top of the base 1. The inside of the second slot 702 is plugged with the second plug 703.

The inside of the chute 706 is slidably connected with the sliding plate 707. The outside of the sliding plate 707 is fixedly connected with the rubber plate 708. The top of the rubber plate 708 is fixedly connected with the top plate 709. When the support plate 601 blocks a large amount of falling rocks, the falling rocks will overflow and roll down again through the protection plate 4. The baffle 705 can be used for secondary blocking, and the rubber plate 708 can protect the baffle 705. The plug-in method of the rubber plate 708 is more convenient for later replacement. The setting of the top plate 709 can play an anti-bouncing effect.

[0023] Furthermore, the inner wall of the second slot 702 is adapted to the outer wall of the second plug 703.
[0024] Working principle: When in use, after fixing the base 1, then hinge the protection plate 4 and attach it to the slope. Then use the first bolt 5 to thread through the top of the protection plate 4 and screw it into the rock formation of the slope to fix the protection plate 4. Support the slope through the protection plate 4. The setting that the protection plate 4 is hinged to the base 1 through the rotating shaft 3 can improve the adaptability to slopes with different steepness. When falling rocks occur, the support plate 601 can play a certain blocking role and slow down the falling speed of the falling rocks. The protection plate 4 fits the steep slope, so that the support plate 601 is inclined, which can better block the falling of the falling rocks. When the support plate 601 blocks a large amount of falling rocks, the falling rocks will overflow and roll down again through the protection plate 4. The baffle 705 can be used for secondary blocking, and the rubber plate 708 can protect the baffle 705. The plug-in method of the rubber plate 708 is more convenient for later replacement. The setting of the top plate 709 can play an anti-bouncing effect.
[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
