[0035] The present invention provides an assembled composite pavement structure, comprising a plurality of frame modules, a plurality of connection modules, a plurality of support modules and a plurality of panel modules;

[0036] like Figure 1 As shown, the cross section of the frame module 1 is U-shaped, and is integrally cast with reinforced concrete, including a bottom plate 11, and side plates 12 erected upward are respectively provided on both sides of the bottom plate 11, and a plurality of circular positioning grooves 13 are provided on the top surface of the bottom plate 12, and the plurality of positioning grooves are arranged in multiple rows on the top surface of the bottom plate, and joints 14 are respectively provided at both ends of the side plates, and vertical mortise and tenon grooves 15 are respectively provided on both sides of the joints at each end of the side plates;

[0037] like Figure 2 , Figure 3 As shown, the connection module 2 includes a long strip connection plate 21, with connection blocks 22 provided at both ends of the connection plate, a slot 221 with an opening facing downward is provided on the connection block at each end in a direction perpendicular to the connection plate, and two vertical tenons 222 are provided on the two side walls in the slot to match the vertical tenons on the joints at both ends of the frame module side plates;

[0038] like Figure 4 As shown, the support module 3 includes a plurality of cylindrical support columns 31, each of which has a central hole 311 at the top, and the plurality of support columns are arranged in a plurality of rows in a manner corresponding to the positioning grooves on the bottom plate of the frame module, and the support columns adjacent in the transverse and longitudinal directions are fixedly connected by connecting rods 32;

[0039] like Figure 5 As shown, the panel module 4 includes a steel panel 41, and a plurality of cylindrical plug-in rods 42 are provided on the bottom surface of the steel panel. The diameter of the plug-in rods 42 is equal to or smaller than the diameter of the central hole 311 on the support column;

[0040] like Figure 6 , Figure 7 As shown, a plurality of frame modules 1 are arranged on the roadbed in sequence end to end, the connecting blocks 22 at both ends of each connecting module 2 are respectively plugged into the joints on the side panels of the two opposite frame modules, and the vertical tenons in the slots of the connecting blocks are respectively inserted into the vertical tenons on the joints of the two frame module side panels to connect the two frame modules; each support module 3 is arranged on the bottom plate of a frame module 1, and the lower ends of the plurality of support columns 31 of the support module are respectively inserted into the plurality of positioning grooves on the bottom plate of the frame module; a plurality of panel modules 4 are supported on the plurality of support modules 3 in sequence end to end, and the plurality of plug-in rods 42 on the bottom surface of the steel panel of each panel module 4 are respectively inserted into the central holes 311 on the tops of the plurality of support columns of the support module.

[0041] When the present invention is implemented, in order to ensure that the road surface can drain quickly on rainy days, a plurality of vertical drainage holes 43 can be provided on the steel panel of each panel module 4, and the position of the vertical drainage holes avoids the position of the positioning column on the bottom surface of the steel panel, and a row of lateral drainage holes 16 are provided at the junction of the side plate and the bottom plate of each frame module 1. With the above structure, rainwater flows from the vertical drainage holes 43 on the steel panel to the bottom plate of the frame module, and is quickly drained to both sides of the roadbed from the lateral drainage holes 16 on the frame module, which can reduce the infiltration of rainwater into the roadbed from the joints between the frame modules, and prevent the roadbed from being soaked by rainwater and reducing its bearing capacity.

Retired fan blades are a kind of composite material with high strength, easy molding, light weight and corrosion resistance. The number of retired fan blades is growing exponentially every year. The traditional treatment method is incineration or thermal digestion, which requires additional investment of a large amount of funds and causes environmental pollution. Using retired fan blades to make the connection module and the support module of the present invention can not only reduce material costs, but also solve the problem of handling retired fan blades, turning waste into treasure, and saving energy and protecting the environment.

[0043] When the present invention is implemented, the cross-section of the joints at both ends of the side panels of each frame module is set to be smaller than the cross-section of the side panels, so that after the connecting module connects two frame modules, the top surface of the connecting block of the connecting module is flush with the top surface of the side panel of the frame module, and the side wall surface of the connecting block of the connecting module is flush with the side wall surface of the side panel of the frame module.

[0044] During the specific implementation of the present invention, in order to ensure that the support module is stably installed on the frame module bottom plate, the outer diameter of the support column of the support module is set to be equal to the diameter of the positioning groove on the frame module bottom plate.

[0045] When the present invention is implemented, when the panel module is installed, the panel module and the frame module can be staggered so that the panel module plays an auxiliary connection role between the frame modules.

[0046] The construction method of the above-mentioned assembled composite pavement structure comprises the following steps:

[0047] (1) Construct the roadbed, ensure the compaction of the base, lay a high-strength and permeable base layer, and meet a certain level of flatness;

[0048] (2) Figure 6 As shown, a plurality of prefabricated frame modules are sequentially placed end to end on the roadbed;
