[0031] In this embodiment, the lifting point I 1.2 includes a lifting point positioning pin 1.2.1, a movable lifting ring 1.2.2, and a lifting point hole 1.2.3; the lifting point positioning pin 1.2.1 is fixedly installed in the lifting point hole 1.2.3, and the movable lifting ring 1.2.2 is disposed on the lifting point positioning pin 1.2.1. The structures of the lifting points II 2.2 and III 3.2 are the same as those of the lifting point I 1.2.

[0032] During hoisting, lifting point I 1.2 is used for lifting the slab. The movable lifting ring 1.2.2 is fixed to the prefabricated pavement edge slab I 1 by lifting point positioning pins 1.2.1, with the top of the pins flush with the surface of edge slab I 1.1. During hoisting, the hook engages the movable lifting ring 1.2.2 for lifting. After hoisting, the movable lifting ring 1.2.2 can be laid flat without affecting the pavement function. The working mechanism of lifting points II 2.2 and III 3.2 is the same as that of lifting point I 1.2.

[0033] In this embodiment, the prefabricated road edge plate I1, prefabricated road edge plate II2, and prefabricated road center plate 3 are configured with the following specifications: a length of 4m (excluding the extension length of the dowel bar); and a width of 2m (measured from the center of the through hole at the fastening serration). Therefore, they can be freely combined and spliced ​​to fit road widths with a modular width of 2m. When the road width is 4m, the prefabricated road edge plates I1 and II2 are directly spliced ​​laterally, with a prefabricated road center plate inserted in the middle for every 2m increase in width.

[0034] In this embodiment, the through-core steel pipe 4 is 4m long and is installed with a 200mm offset from the prefabricated road panel. Each prefabricated road panel has an 8mm thick steel sheet protective frame around its perimeter to protect the panel and ensure a smooth surface for easy assembly.

[0035] In this embodiment, double-layer bidirectional reinforcing bars are arranged in the edge plate I plate 1.1, the edge plate II plate 2.1, and the middle plate 3.1. The reinforcement of precast concrete pavement slabs is common knowledge in the field, so the present invention will not draw or describe the reinforcement method in detail.

[0036] Working principle:

[0037] Prefabricated pavement edge panel I1, prefabricated pavement edge panel II2, and prefabricated pavement center panel 3 are connected by fastening saw teeth to replace the function of traditional cast-in-place pavement tie rods. Then, through-hole steel pipe 4 is installed to connect the prefabricated pavement panels by passing through the reserved through-hole.

[0038] The prefabricated pavement panels are longitudinally equipped with dowel bars, which are inserted into connecting holes to connect the front and rear panels. These dowel bars transmit vehicle loads, preventing misalignment and uneven settlement. The connecting holes are slightly larger than the diameter of the dowel bars; one end of the dowel bar is fixed, while the other end can slide within adjacent panels. This facilitates installation while allowing the pavement panels to expand and contract due to temperature changes, preventing cracks caused by constraint deformation. Furthermore, it also serves to connect and secure adjacent panels.

[0039] Since one end of the dowel bar extends out of the prefabricated pavement panel and the through steel pipe is installed with a 200mm offset, a prefabricated end block 5 is designed for end treatment. The through crescent arc 5.3 of two adjacent prefabricated end blocks 5 wraps around the through steel pipe 4 and the dowel bar is inserted into the connecting hole Ⅳ5.2, which protects the components and ensures the safety of this utility model.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
