Detailed Description
The utility model is further illustrated with reference to the following figures and examples.
As shown in the attached drawings, the pier pile protection structure comprises a pier pile 1, wherein a protection cylinder 2 is arranged on the periphery of the pier pile 1, and a buffer layer 3 is arranged between the protection cylinder 2 and the pier pile 1; the outer side of the protection cylinder 2 is provided with a bulge 201, and the inner side of the protection cylinder 2 is provided with a hollow part 202 corresponding to the bulge 201.
The buffer layer 3 fills the hollow portion 202. When water flow and sand impact the protective cylinder 2, the protective cylinder 2 can counteract partial abrasion and impact of the water flow and sand on the protective cylinder 2. Under extreme condition, when rivers, grit exceeded a definite value to the impact of protection section of thick bamboo 2, the arch 201 on the protection section of thick bamboo 2 is sunken in order to cushion the energy-absorbing, effectively reduces rivers, grit to the impact of pier pile foundation 1. Meanwhile, the deformation buffering energy absorption characteristic of the buffer layer 3 is fully utilized, the impact force is further dispersed and reduced, and the pier foundation 1 is further protected.
The protrusion 201 and the hollow part 202 have various structural forms, and preferably, the protrusion 201 and the hollow part 202 are both annular structures coaxially arranged with the pier foundation 1; the protrusions 201 of the annular structure are arranged in a plurality at intervals along the axial direction of the pier foundation 1. A plurality of protruding 201 forms crest trough structure, and rivers and grit are to ring diffusion under the effect of crest trough structure to the impact of pier pile foundation 1.
