[0027] In this embodiment, the utility model has a simple and reasonable structure. First, the top concrete block 1 and the bottom concrete block 2 are used to set the upper and lower fixed basic structure. Then, the slope surfaces of the slope bodies are sequentially spliced ​​and installed with the splicing protective plates 3. By inserting the structure of the protrusions 4 and the insertion grooves 5, quick splicing and installation can be achieved.
