Technical Field

[0001] The utility model relates to the technical field of assembled pavement structures, in particular to an assembled recycled concrete pavement structure. Background Technique

[0002] An assembled concrete pavement is a pavement formed by assembling precast concrete bricks. Using recycled concrete to precast concrete bricks can reduce costs and save resources, so it has become the first choice for precast concrete bricks.

[0003] The construction of an assembled concrete pavement is relatively fast. It can be constructed at night in busy traffic sections without a large number of concrete pouring, knocking and other operations. Therefore, the construction noise generated is relatively small, reducing the impact on surrounding residents and also reducing traffic jams and impacts.

[0004] For example, the Chinese invention patent application with the application number 202210113019.1 provides a precast slab structure for mine pavement laying, and realizes the connection between adjacent concrete slabs by arranging adjacent rectangles of steel outside the concrete slab.

[0005] However, this connection method is too cumbersome and has the disadvantage of high alignment difficulty. Therefore, it will increase the pavement laying difficulty, reduce the construction efficiency, and cannot meet the actual construction requirements. Content of the Utility Model

[0006] The purpose of the utility model is to provide an assembled recycled concrete pavement structure to solve the technical problem of low laying efficiency of the current assembled recycled concrete pavement.

[0012] Further defined, the number of the reserved grooves and the number of the clamping blocks are equal and both are multiple. The multiple reserved grooves are arranged at intervals along the length direction of the second docking member, and the multiple clamping blocks are arranged at intervals along the length direction of the first docking member. The clamping blocks and the reserved grooves are arranged in one-to-one correspondence.

[0013] Further defined, a first reserved hole is formed in the clamping block, a second reserved hole is formed in the reserved groove, and a bolt matched with the second reserved hole is arranged on the first reserved hole.

[0014] Further defined, a nut is arranged at the top of the bolt, and a pile head is arranged at the bottom of the bolt.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1.

Specific embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the attached drawings in the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0027] Please refer to Figures 1-5 , a prefabricated recycled concrete road surface structure provided by the present utility model includes a plurality of sequentially spliced recycled concrete road surface main bodies. The recycled concrete road surface main bodies are prefabricated from recycled concrete, so that the recycled concrete road surface main bodies include a recycled concrete layer 14.

[0028] The main body of the recycled concrete pavement is a rectangular structure, which is convenient for pavement construction. A first docking member 5 and a second docking member 3 matching the first docking member 5 are respectively arranged on opposite sides of the main body of the recycled concrete pavement, facilitating the clamping and matching of two adjacent main bodies of the recycled concrete pavement, so that it is more convenient to align and join during pavement assembly.

[0029] Specifically, a reserved groove 4 is formed at the top of the second docking member 3, and a clamping block 10 matching the reserved groove 4 is arranged at the bottom of the first docking member 5, enabling two adjacent main bodies of the recycled concrete pavement to be joined by clamping the clamping block 10 with the reserved groove 4 during assembly.

[0030] To ensure stable joining, it is preferred that the number of reserved grooves 4 is multiple. Taking three as an example, the number of corresponding clamping blocks 10 is also three. The three clamping blocks 10 are arranged at equal intervals along the length direction of the first docking member 5, and the corresponding reserved grooves 4 are also arranged at equal intervals along the length direction of the second docking member 3, so that the reserved grooves 4 and the clamping blocks 10 are arranged in one-to-one correspondence for convenient clamping.

[0031] To further ensure the stable joining of the main body of the recycled concrete pavement, a first reserved hole 9 is formed on the clamping block 10, a second reserved hole 19 is formed in the reserved groove 4, and a bolt 8 is arranged on the first reserved hole 9. When the pavement is assembled and paved, after the clamping block 10 is clamped with the corresponding reserved groove 4, the bolt 8 is inserted into the first reserved hole 9 and the second reserved hole 19, thereby improving the assembly reliability of two adjacent main bodies of the recycled concrete pavement.

[0032] To avoid the top of the bolt 8 being exposed and affecting pedestrians and vehicles, a reserved sunk groove 6 is formed on the clamping block 10, and the first reserved hole 9 is formed at the bottom of the reserved sunk groove 6, so that the top of the bolt 8 is located inside the first reserved hole 9.

[0033] A nut 7 is arranged at the top of the bolt 8, and a pile head 20 is arranged at the bottom of the bolt 8, facilitating it to extend into the ground to improve the pavement stability. A buffer cushion plate 12 is sleeved outside the bolt 8, and an elastic element 11, such as a rubber pad, is arranged between the buffer cushion plate 12 and the nut 7. The buffer cushion plate 12 is arranged at the bottom of the reserved sunk groove 6, thereby making the connection between the bolt 8 and the clamping block 10 more stable.

[0034] The main body of the recycled concrete pavement further includes a base layer 13, the base layer 13 is located below the recycled concrete layer 14, a wear-resistant surface layer 15 is arranged on the top of the recycled concrete layer 14, and the wear-resistant surface layer 15 is made of anti-slip imitation stone particles to improve the wear resistance and anti-slip performance.

[0035] In order to improve the structural strength of the main body of the recycled concrete pavement, it is selected to arrange a first reinforcing rib 16 and a third reinforcing rib 18 in the recycled concrete layer 14, and a second reinforcing rib 17 is evenly distributed between the first reinforcing rib 16 and the third reinforcing rib 18. Both the first reinforcing rib 16 and the third reinforcing rib 18 are arranged along the length direction of the main body of the recycled concrete pavement, and the second reinforcing rib 17 is arranged along the longitudinal direction of the main body of the recycled concrete pavement.

[0036] Working principle:

[0037] Taking two main bodies of recycled concrete pavement as an example for illustration, the two main bodies of recycled concrete pavement are the first pavement main body 1 and the second pavement main body 2 respectively.

[0038] During assembly, the clamping block 10 of the first docking part 5 on the second pavement main body 2 is clamped with the reserved groove 4 on the second docking part 3 on the first pavement main body 1, which is convenient for the positioning and connection between the first pavement main body 1 and the second pavement main body 2.

[0039] After that, the first docking part 5 of the second pavement main body 2 and the second docking part 3 of the first pavement main body 1 are connected by bolts 8 and locked and fixed by nuts 7. The buffer cushion plate 12 is closely attached to the reserved sunk groove 6 opened on the top surface of the first docking part 5, so that the nut 7 extends into the reserved sunk groove 6, which is not easy to affect the flatness of the surface of the assembled pavement.

[0040] A pile head 20 is arranged at the bottom end of the bolt 8, which is beneficial to insert into the ground to improve the grip and prevent the first pavement main body 1 and the second pavement main body 2 from sliding easily after being laid.

[0041] The elastic element 11 between the buffer cushion plate 12 and the nut 7 is made of a rubber strip. When being frequently squeezed and collided by vehicles, the external force can be dispersed through the buffering and restoring action of the elastic element 11, so that the nut 7 is not easy to loosen, and the stability of the assembled first pavement main body 1 and second pavement main body 2 is improved.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
