[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] In another embodiment of the present application, a rooted pile pier bottom protection facility is provided, including a pier 1, with a rooted pile 2 fixedly installed at the bottom of the pier 1, and also including: a protection component 3, arranged at the bottom of the pier 1 and distributed at equal intervals around the rooted pile 2, for blocking and protecting against gravel impacting the river; a buffer component 4, arranged between the protection component 3 and the rooted pile 2, for buffering and unloading the impact force at the protection component 3; a rotating component 5, arranged between the rooted pile 2 and the buffer component 4, and one side of the rotating component 5 is installed on the surface of the rooted pile 2, for transferring the impact force of the gravel.

[0039] In the present invention, when in use, a barrier portion is formed by splicing the protection component 3, the buffer component 4 and the rotating component 5, and then a plurality of barrier portions are installed in a circular shape on the surface of the root pile 2 to form a complete barrier protection facility, which is convenient for providing a good barrier protection effect on all sides of the root pile 2. A completed barrier portion can be distributed vertically at equal intervals on the surface of the root pile 2 to enclose and protect the area between the top of the root pile 2 and the bottom of the pier 1. When gravel in the river impacts the pier foundation, the impacted gravel is enclosed by the protection component 3 to avoid contact between the gravel and the foundation, thereby achieving a good protection effect, preventing damage to the pier and reducing river scouring and erosion. On the other hand, when the gravel contacts the protection component 3, the impact force generated by the gravel can be buffered and unloaded, thereby improving the protection of the protection component 3. The effect is that in the process of the protective component 3 buffering and unloading the gravel, the impact force generated by the gravel is used to drive the buffer component 4 on one side of the protective component 3 to run synchronously, so that the airbag 405 in the buffer component 4 is inflated and swells, generating an opposite force, and the impact force of the gravel collision offsets the rebound, thereby further weakening the impact force brought by the gravel, and having a good protective effect on the connection between the bottom of the pier 1 and the root pile 2, thereby improving the overall stability of the structure. After the buffer component 4 further buffers and unloads the impact force generated by the collision of the gravel, the protective component 3 and the buffer component 4 are driven by the rotating component 5 to rotate around the surface of the root pile 2, and the impact force transmitted to the gravel is transferred to one side of the pier foundation, thereby further improving the protective effect of the device and preventing the gravel from accumulating at the bottom of the pier foundation.
