[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] In the drawings, the same reference numerals all refer to the same components.

[0023] Example 1

[0024] like Figure 1-4 As shown, it includes two first fixing blocks 1, a second fixing block 2 is arranged on the top of the first fixing block 1, the first fixing block 1 and the second fixing block 2 are both semi-conical, and the first fixing block 1 and the second fixing block 2 are penetrated by a semicircular mounting groove 3, the inner wall of the semicircular mounting groove 3 is annularly distributed with arc-shaped connecting blocks 4, and the surface of the arc-shaped connecting block 4 is evenly distributed with connecting blocks 5, one end of the connecting block 5 is provided with a connecting ring 6, one end of the connecting ring 6 is provided with a buffer damper 7, one end of the buffer damper 7 is commonly connected with an annular contact block 8, and the connecting rings 6 in the same vertical direction are commonly connected with a positioning rod 9.

[0025] Furthermore, the first fixed block 1 and the second fixed block 2 are installed opposite to each other, and the narrow opening of the first fixed block faces downward. When a landslide occurs, the spatial angle between the first fixed block 1 and the ground can divert the debris flow with a smaller flow rate to the two sides of the first fixed block 1, thereby reducing the impact force of the debris flow. The space formed by the first fixed block 1 and the second fixed block 2 can divert the top of the debris flow when the flow rate is large, and in cooperation with the first fixed block 1, the debris flow can be diverted in sections, thereby reducing the impact force of the debris flow and reducing the impact force on the bridge piers.

[0026] Arc-shaped reinforcement blocks 10 are disposed on the surfaces of the first fixing block 1 and the second fixing block 2 , and auxiliary reinforcement blocks 11 perpendicular to the reinforcement blocks 10 are disposed on the surfaces of the first fixing block 1 and the second fixing block 2 .

[0027] The surfaces of the first fixed block 1 and the second fixed block 2 are provided with raised anti-collision bodies 12. When a landslide occurs, boulders may roll down and the raised anti-collision bodies 12 may contact the boulders in advance. The raised anti-collision bodies 12 may prevent the surfaces of the first fixed block 1 and the second fixed block 2 from being damaged.

[0028] A connecting groove 13 is provided in the center of the annular contact block 8, and evenly distributed C-shaped connecting blocks 14 are arranged inside the connecting groove 13. After a landslide, soil blocks and boulders will hit the surfaces of the first fixed block 1 and the second fixed block 2. The first fixed block 1 and the second fixed block 2 will be subjected to the impact force and will move toward the bridge pier. The impact resistance of the debris flow is reduced through the positioning rod 9 and the buffer damping 7. The annular contact block 8 and the evenly distributed C-shaped connecting blocks 14 inside it can reduce the impact force transmitted to the bridge pier.

[0029] The length of the positioning rod 9 is twice the height of the first fixed block 1 and the second fixed block 2. By passing the positioning rod 9 through the connecting ring 6 in the same vertical direction, half of the positioning rod 9 will be driven into the ground to achieve its positioning function, thereby avoiding displacement of the first fixed block 1 and the second fixed block 2 and protecting the bridge pier.

[0030] One side of the first fixing block 1 and the second fixing block 2 is provided with a mounting groove 15, and the other side of the first fixing block 1 and the second fixing block 2 is provided with a mounting block 16. During installation, the openings of the two first fixing blocks 1 are facing each other, and the mounting block 16 of one first fixing block 1 is installed into the inside of the mounting groove 15 of the other first fixing block 1, and the two first fixing blocks 1 and the second fixing blocks 2 are spliced ​​to protect the bridge pier.

[0031] The anti-collision body 12 is distributed horizontally, and includes an anti-collision core 17. The surface of the anti-collision core 17 is covered with a surface layer 18. The anti-collision core 17 is cast by concrete, and the surface layer 18 is made of steel material. The steel material has a higher surface hardness than the boulder, which can prevent the surface of the first fixed block 1 and the second fixed block 2 from being damaged.

[0032] Specifically, during installation, the openings of the two first fixing blocks 1 are opposed to each other, and the mounting block 16 of one of the first fixing blocks 1 is installed inside the mounting groove 15 of the other first fixing block 1, the two first fixing blocks 1 and the second fixing block 2 are spliced, and then the positioning rod 9 is passed through the connecting ring 6 in the same vertical direction, and half of the positioning rod 9 is driven into the ground to achieve the positioning function, thereby avoiding the displacement of the first fixing block 1 and the second fixing block 2, so that the pier is protected. The first fixing block 1 and the second fixing block 2 are installed relative to each other, and the narrow opening of the first fixing block is downward. When a landslide occurs, the spatial angle between the first fixing block 1 and the ground can divert the debris flow with a smaller flow to the two sides of the first fixing block 1, thereby reducing the impact force of the debris flow. The space formed by the fixed block 1 and the second fixed block 2 can divert the top of the debris flow when the flow rate is large, and can divert the debris flow in sections in cooperation with the first fixed block 1, thereby reducing the impact force of the debris flow and reducing the impact force on the bridge piers. When a landslide occurs, huge rocks will roll down, and the raised anti-collision body 12 can contact the huge rocks in advance. The raised anti-collision body 12 can prevent the surfaces of the first fixed block 1 and the second fixed block 2 from being damaged. During the impact, the first fixed block 1 and the second fixed block 2 will be subjected to the impact force and will move toward the bridge piers. The impact resistance of the positioning rod 9 and the buffer damping 7 can reduce the impact capacity of the debris flow. The annular contact block 8 and the C-shaped connecting block 14 evenly distributed therein can reduce the impact force transmitted to the bridge piers.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
