Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 One embodiment provided by this utility model:
[0025] A prefabricated scour protection structure for river embankment construction includes:
[0026] The main body includes a bottom protection block 1. The surface of the bottom protection block 1 is fixedly connected with a lifting ring 11 and a connecting ring 12. The surface of the connecting ring 12 is connected with a connecting rod 13. The bottom protection block 1 is a precast concrete block in the shape of a trapezoid. The laying of multiple sets of bottom protection blocks 1 can form a bottom protection structure. The lifting ring 11 allows the lifting device to move the bottom protection block 1 to the position to be laid. There are four sets of connecting rings 12 located on the four sides of the bottom protection block 1. Adjacent bottom protection blocks 1 are connected by two sets of connecting rods 13.
[0027] The connecting mechanism includes a mounting block 2, which is mounted on the surface of the connecting rod 13. The surface of the mounting block 2 has an insertion hole 21 and a mounting groove 22. A screw 23 is fixedly connected to the surface of the connecting rod 13, and a nut 24 is abutted to the surface of the mounting block 2. The mounting block 2 can realize the connection of two sets of connecting rods 13, and the connection between two sets of adjacent bottom protection blocks 1 can be realized by the insertion of the connecting rod 13 and the connecting ring 12.
[0028] Furthermore, two sets of insertion holes 21 and mounting slots 22 are provided. The two sets of insertion holes 21 and mounting slots 22 are opened on both sides of the mounting block 2. Each set of insertion holes 21 and mounting slots 22 has two insertion holes 21. Each set of insertion holes 21 is inserted and connected to both ends of the connecting rod 13. The length of the mounting slot 22 is the same as the length of the insertion hole 21. The connecting rod 13 can be installed through the insertion hole 21, while the screw 23 can be installed through the mounting slot 22. The diameter of the connecting rod 13 is the same as the diameter of the insertion hole 21, and the connecting rod 13 is connected to the surface of the mounting block 2 through the insertion hole 21.
[0029] Furthermore, two sets of screws 23 are provided, and the two sets of screws 23 are installed on both sides of the connecting rod 13. The screws 23 are installed on the surface of the mounting groove 22. One end of the screw 23 is fixedly connected to the surface of the connecting rod 13, and the other end of the screw 23 is threadedly connected to the surface of the nut 24. The two sets of screws 23 are symmetrically arranged. With the connection of the screws 23 and the nuts 24, the connecting rod 13 can be limited and fixed on the surface of the insertion hole 21.
[0030] Furthermore, the surface of the bottom protection block 1 is provided with a reinforcing mechanism, which includes a vertical rod 3. The vertical rod 3 is fixedly connected to the surface of the bottom protection block 1. A sleeve 31 is fitted onto the surface of the vertical rod 3. A movable block 32 is fixedly connected to the surface of the sleeve 31. A side rod 33 is movably connected to the surface of the sleeve 31. A side plate 34 is movably connected to the surface of the side rod 33. A fixing block 35 is fixedly connected to the surface of the vertical rod 3. A connecting hole 36 is opened on the surface of the movable block 32. A connecting block 37 is fixedly connected to one end of the side rod 33. A rotating hole 38 is opened at the other end of the side rod 33. The vertical rod 3 can form a triangular structure with the two sets of side rods 33 and side plates 34 respectively. This allows the side rods 33 and side plates 34 inserted into the soil layer to open up when the bottom protection block 1 is installed on the soil surface and subjected to a lifting force, thereby making the connection between the bottom protection block 1 and the river soil layer tighter and more secure.
[0031] Furthermore, there are two sets of movable blocks 32, side plates 34 and fixed blocks 35. The two sets of movable blocks 32 and side plates 34 are installed on both sides of the sleeve 31, and the two sets of fixed blocks 35 are installed on both sides of the upright 3. There are two movable blocks 32 and side plates 34 in each set. The movable blocks 32 and side plates 34 are attached to both sides of the side rod 33. The side rod 33 can be installed through the movable blocks 32, and the side plates 34 can be installed through the fixed blocks 35. One end of the side rod 33 moves on the surface of the movable block 32 through the connection of the connecting block 37 and the connecting hole 36, while the other end moves on the surface of the side plate 34 through the connection of the rotating hole 38 and the rotating block 39.
[0032] Furthermore, one end of the side plate 34 is movably connected to the surface of the side rod 33, and the other end of the side plate 34 is movably connected to the surface of the fixing block 35.

[0033] Furthermore, there are two sets of rotating holes 38 and rotating blocks 39. One set of rotating holes 38 is opened on the surface of the side rod 33, and the other set of rotating holes 38 is opened on the surface of the fixing block 35. The two sets of rotating blocks 39 are installed at both ends of the side plate 34. The diameter of the rotating hole 38 is the same as the diameter of the rotating block 39. The rotating block 39 is installed on the surface of the rotating hole 38. Two adjacent side plates 34 are connected through the rotating block 39. When the sleeve 31 moves, it can drive the side plate 34 to rotate around the rotating block 39 connected on the fixing block 35 as the center. The rotating block 39 is rotatably connected to the surface of the rotating hole 38.
[0034] Working principle: When assembling the bottom protection structure and connecting two adjacent bottom protection blocks 1, first insert the two sets of connecting rods 13 into the adjacent connecting rings 12 respectively, and then install the two sets of connecting rods 13 on the mounting block 2 in sequence, so that the two ends of the connecting rods 13 are inserted into the insertion holes 21 and penetrate the surface of the mounting block 2, so as to drive the screw 23 to slide on the surface of the mounting groove 22. After the mounting block 2 and the two sets of connecting rods 13 are connected, the nut 24 is connected to the surface of the screw 23 by thread and after tightening, it is pressed against the surface of the mounting block 2 to complete the connection and fixation between the two sets of connecting rods 13 and realize the connection between the two bottom protection blocks 1 through the connecting ring 12.
[0035] Before laying the bottom protection block 1, the sleeve 31 is slid on the surface of the upright 3 to drive one end of the side rod 33 to rotate around the connecting block 37 and the other end to rotate around the rotating block 39 installed on its surface, so that the side plate 34 rotates around the rotating block 39 on the fixed block 35. The two sets of rotating blocks 39 rotate on the surfaces of the two sets of rotating holes 38 respectively, so that the side rod 33, the side plate 34 and the bottom protection block 1 form a triangular structure. At this time, the reinforcing mechanism is buried in the riverbed soil layer, thereby strengthening the connection between the bottom protection block 1 and the soil layer.
