[0039] As shown in Figure 1 , Figure 4 and Figure 6As shown, the seismic isolation trench cover structure with a self-resetting function of the present invention is used to cover the seismic isolation trench 13. The first wall 11 and the second wall 12 are provided on both sides of the seismic isolation trench 13. The seismic isolation trench 13 is located between the corresponding side portions of the first wall 11 and the second wall 12. The seismic isolation trench 13 is provided on the periphery of the building structure. The seismic isolation trench 13 is annular and is provided in a circle on the outside of the building structure. The seismic isolation trench 13 is used to provide a good seismic isolation effect for the building structure.

[0067] 3. The cover plate structure can effectively avoid damage to the cover plate and the surrounding building structure: the right-angled triangular arch design (i.e. the design of the guide plate) on one side of the base plate can guide the lower cover plate and the upper cover plate to tilt upward when the walls deform in the same direction, thereby effectively protecting the surrounding building structure, prolonging the service life of the entire building structure, and improving the safety and stability of the building.

[0068] 4. The cover plate structure can reduce component wear: the soft pad layer in the U-shaped groove of the mounting piece is made of flexible material, which can reduce wear between components during movement and prolong the service life of the structure.

[0069] 5. The cover plate structure is easy to install and splice: the splicing between the cover plates is simple and easy to operate, and during installation, the construction personnel only need to fasten the buckles of the cover plates to connect, and the splicing work can be quickly completed; this design not only improves the construction efficiency, but also ensures the accuracy and stability of splicing, reduces the construction difficulty, and makes the structure more advantageous in practical application.
