[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1As shown, a prefabricated road module for temporary roads includes a road slab 1 and steel corner guards 2.

[0018] like Figure 1 , Figure 2 As shown, the road slab 1 is a long, narrow plate that is laid horizontally on the ground. Several permeable holes 11 are installed through vertical pipes on the road slab 1 to automatically drain surface water and ensure normal passage of the road slab 1.

[0019] like Figure 1 , Figure 2 As shown, a protrusion 12 with a trapezoidal cross-section is provided on one side of the road slab 1, and a groove 13 for the protrusion 12 to be inserted is provided on the other side.

[0020] Therefore, during the assembly of road slab 1, the mortise and tenon joint of protrusion 12 and groove 13 enables the snap-fit ​​between two adjacent road slabs 1, achieving stable splicing of road slab 1, effectively limiting the horizontal displacement between road slabs 1, and improving the overall stability and flatness of the temporary road.

[0021] like Figure 1 , Figure 2 As shown, the steel corner guards 2 are installed at the corners of the road slab 1 to prevent damage to the corners of the road slab 1 during hoisting and heavy vehicle rolling, thus extending its service life.

[0022] like Figure 1 , Figure 3 As shown, the steel corner guard 2 includes an end 21 and a connecting rod 22. The end 21 is fastened to the two end corners of the road slab 1. The connecting rod 22 has a right-angled cross-section and is fastened to the four corners of the road slab 1, and connects to a pair of end 21.

[0023] like Figure 3 , Figure 4 As shown, the connecting rod 22 includes a pair of rod bodies 23, an inner plate 24, and an outer plate 25. The rod body 23 is fixed to the end 21 and fastened to the corner of the road slab 1. The inner plate 24 and the outer plate 25 are respectively disposed at the ends of the pair of rod bodies 23 and overlap each other.

[0024] like Figure 3 , Figure 4 As shown, screws 26 are provided through the outer plate 25 and the inner plate 24, the road plate 1 is provided with a pre-made threaded tube 27 for screws 26 to be screwed into, and the surface of the outer plate 25 is provided with a receiving groove 28 for screws 26 to be embedded.

[0025] After the road slab 1 is produced, the steel corner protectors 2 are taken out, and the connecting rods 22 are fastened to the four corners of the road slab 1. Then, the end 21 is pushed to move the steel corner protectors 2 from both sides of the road slab 1 toward the middle, and the end 21 is fastened to the corner of the end of the road slab 1.

[0026] At this point, the pair of poles 23 are close to each other, and the outer plate 25 and the inner plate 24 overlap. Then, the screw 26 passes through the outer plate 25 and the inner plate 24 and is tightened into the threaded tube to fix the entire steel corner guard 2. The screw 26 is hidden inside the outer plate 25 and will not affect the flatness of the road slab 1.

[0027] Then, the road slab 1 can be hoisted and laid horizontally on the ground. Then, the road slabs 1 are controlled to move closer to each other so that the protrusions 12 on the adjacent road slabs 1 are embedded into the grooves 13, thereby splicing and fixing the road slabs 1 and completing the on-site construction of the temporary road.

[0028] like Figure 2 As shown, hooks 3 are provided at the four corners of the upper surface of the road slab 1. Each hook 3 includes a rod 31 and a ring 32. The rod 31 is vertically embedded in the road slab 1, and the ring 32 is rotatably connected to the rod 31. The road slab 1 is provided with a storage groove 33 for the ring 32 to be inserted after being flipped over. A cover plate 34 covering the ring 32 is fastened inside the storage groove 33.

[0029] When it is necessary to hoist the road slab 1, first open the cover plate 34, then control the lifting ring 32 to flip to a vertical position, thus hoisting the road slab 1. After hoisting is completed, control the lifting ring 32 to flip to a horizontal position, then fasten the cover plate 34 to achieve concealed storage of the hook 3, thereby making the assembly and transportation process of the road slab 1 easier and more convenient.

[0030] In the actual production process of road slab 1, road slab 1 is preferably a rectangular slab with dimensions of 1000mm×500mm×150mm. Road slab 1 is made of recycled aggregate concrete, wherein the preferred mix ratio of recycled aggregate concrete is (per cubic meter): 398kg cement, 280kg water, 186kg natural medium sand, 378kg natural gravel (5-31.5mm) and 1187kg recycled aggregate.

[0031] The recycled aggregate consists of construction waste such as waste bricks and blocks generated on the construction site. After being crushed by a jaw crusher and screened by a vibrating screen, it is composed of 0-5mm recycled fine aggregate (replacing part of the sand) and 5-30mm recycled coarse aggregate (replacing part of the gravel), realizing the resource utilization of construction solid waste. At the same time, the road slab 1 is equipped with a steel reinforcement skeleton to enhance its bending and crack resistance.

[0032] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
