[0002] A road culvert is a tunnel structure used to cross roads or other traffic channels. It is usually designed to contain rivers, streams or other water bodies to ensure that traffic channels such as roads or railways can pass smoothly. The design and construction of culverts involve various engineering aspects, including geological conditions, hydrological conditions and traffic engineering. In order to ensure the stability and safety of the culvert, spring plates are often installed inside the culvert. The spring plates are usually made of elastic materials and can have a certain deformation and buffering capacity under external pressure or vibration. Such a design can help reduce the adverse effects of the culvert structure on groundwater flow or underground structures.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-2 The utility model provides an embodiment: an antifreeze spring plate structure for passing under a road heat culvert, comprising a plurality of spring plates 1, the spring plates 1 being arranged in an upper large-size and lower small shape, a rubber pad 2 being arranged between two adjacent spring plates 1, a concave hole 3 being provided inside the spring plate 1 and the rubber pad 2, a central column 4 being arranged inside the spring plate 1, a side wall of the central column 4 being slidably connected inside the concave hole 3, a side wall of the central column 4 being fixedly connected to a limiting plate 5, a side wall of the limiting plate 5 being slidably connected inside the concave hole 3, a side wall of the limiting plate 5 being slidably connected to a rubber sheet 6 being arranged on the side wall of the limiting plate 5, and the rubber sheet 6 being arranged on the At the bottom of the spring plate 1, the side wall of the limit plate 5 is slidably connected with a rubber sheet 29, and the rubber sheet 29 is arranged on the upper surface of the spring plate 1. The side wall of the limit plate 5 is slidably connected with a gasket 8. The inner part of the limit plate 5 is threadedly connected with a fixing bolt 7. The lower surface of the gasket 8 fits with the upper surface of the rubber sheet 29. An auxiliary component is arranged inside the spring plate 1. The auxiliary component includes a positioning column 18 and a latch 17. A through hole 16 is opened inside the spring plate 1 and the rubber pad 2. The side wall of the positioning column 18 is slidably connected inside the through hole 16, and the side wall of the latch 17 is slidably connected inside the positioning column 18.
[0023] During the assembly process of the spring plate 1, the spring plates 1 need to be arranged in order from large to small, then the rubber pad 2 is placed between two adjacent spring plates 1 and the concave hole 3 and the through hole 16 opened inside the spring plate 1 and the rubber pad 2 are ensured to be in the same straight line. After the spring plate 1 and the rubber pad 2 are prepared, the rubber sheet 1 6 is sleeved on the side wall of the limiting plate 5, and then the limiting plate 5 together with the center column 4 are inserted into the concave hole 3 from the bottom of the spring plate 1. This is to limit the spring plate 1 and the rubber pad 2 to ensure that they maintain a stable position during the subsequent assembly process. Next, the rubber sheet 2 9 and the gasket 8 are sleeved on the limiting plate 5 in sequence. This step is to increase the friction between the spring plate 1 and the rubber pad 2, thereby improving the stability of the assembly. After completing this step, the fixing bolt 7 is twisted inside the center column 4. Finally, the gasket 8 is squeezed to complete the preliminary assembly of the spring plate 1. After the initial assembly is completed, the positioning column 18 is inserted into the through hole 16 to fix the spring plate 1 and the rubber pad 2 again to ensure that they will not shift during actual use. Finally, the latch 17 is inserted into the positioning column 18 to complete the final assembly of the spring plate 1 and the rubber pad 2. When the spring plate 1 expands and contracts due to changes in ambient temperature, the rubber pad 2 can provide a buffering effect to prevent the spring plate 1 from breaking.
[0024] Reference Figure 3 A side ring 10 is fixedly connected to the upper surface of the top spring plate 1, and a limiting column 11 is fixedly connected inside the side ring 10. A return spring 12 is arranged inside the limiting column 11, and a fixed block 13 is arranged inside the limiting column 11. One end of the return spring 12 is fixedly connected to the limiting column 11, and the other end of the return spring 12 is fixedly connected to the side wall of the fixed block 13. A sliding column 14 is connected to the side wall of the fixed block 13. The side wall of the sliding column 14 is slidably connected to the limiting column 11. A splint 15 is fixedly connected to the side wall of the sliding column 14. The side wall of the splint 15 is set to an arc angle, and the limiting columns 11 are arranged axially symmetrically inside the side ring 10.
[0025] After the spring plate 1 is assembled, the next step is to pass the pipe through the inside of the side ring 10. During this process, the pipe will exert an extrusion force on the clamping plate 15, causing it to move outward. At the same time, after being squeezed, the sliding column 14 will slide into the inside of the limiting column 11. As the sliding column 14 slides, the return spring 12 will be gradually squeezed, causing it to shrink. When the return spring 12 shrinks to a certain extent, it will generate a return force. This force will limit the pipe inside the side ring 10, achieving precise position limiting of the pipe.
[0026] Working principle: When assembling the spring plates 1, first arrange the spring plates 1 in a way that the upper one is larger and the lower one is smaller, and place the rubber pads 2 between the two adjacent spring plates 1. At this time, the recessed holes 3 and the through holes 16 opened inside the spring plates 1 and the rubber pads 2 are just in the same straight line. This is to sleeve the rubber sheet 1 6 on the side wall of the limiting plate 5, and then insert the limiting plate 5 together with the center column 4 from the bottom of the spring plate 1 into the recessed hole 3 to limit the spring plate 1 and the rubber pad 2. Then, sleeve the rubber sheet 2 9 and the gasket 8 on the limiting plate 5 in sequence, and finally twist the fixing bolt 7 inside the center column 4. The part is assembled and the gasket 8 is squeezed to complete the preliminary assembly of the spring plate 1. After the installation is completed, the positioning column 18 is inserted into the through hole 16, and finally the latch 17 is inserted into the positioning column 18 to fix the spring plate 1 and the rubber pad 2 again. After fixation, the pipe is passed through the inside of the side ring 10. The pipe will squeeze the clamping plate 15 to move it outward, and the sliding column 14 will slide into the inside of the limiting column 11, squeezing the return spring 12 to shrink it, and the force generated by the return spring 12 will limit the pipe inside the side ring 10 to limit it.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
