[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides Figs. 1-4 A novel prefabricated concrete square culvert shown in FIG. 1 includes a square culvert body 1, a slot 2 provided at one end of the square culvert body 1, two slots 2 provided, the two slots 2 being respectively distributed on both sides of the inner cavity of the square culvert body 1, and the slots 2 passing through the upper surface of the square culvert body 1, and a grouting port 5 provided at the top of the slot 2 for facilitating the injection of cement mortar from the grouting port 5 into the interior of the slot 2 from top to bottom.

[0027] The height of the slot 2 is half or one third of the height of the square culvert body 1 and can be adjusted according to specific usage. The slot 2 does not completely penetrate the square culvert body 1 to ensure the stability of the overall structure of the square culvert body 1.

[0028] To facilitate the assembly of two adjacent square culvert bodies 1, a first limiting assembly that cooperates with the card slot 2 is provided at the other end of the square culvert body 1. The first limiting assembly includes a first limiting rod 3 and a first limiting plate 4. The first limiting rod 3 is provided on the square culvert body 1, and the first limiting plate 4 is fixedly connected to the end of the first limiting rod 3 away from the square culvert body 1.

[0029] By providing structures such as the card slot 2, the first limiting rod 3 and the first limiting plate 4, when splicing two square culvert bodies 1, the first limiting rod 3 and the first limiting plate 4 of one square culvert body 1 are made to enter the card slot 2 of the other square culvert body 1, and the first limiting plate 4 abuts against the bottom end of the card slot 2. By utilizing the card slot 2 and the first limiting rod 3 and the first limiting plate 4 to cooperate with each other, the alignment and installation of the two square culvert bodies 1 can be quickly completed, thereby improving the convenience of splicing the square culvert bodies 1.

[0030] The card slot 2 is T-shaped, so that after installation, the two square culvert bodies 1 are not easily separated, which can improve the stability of the docking.

[0031] One end of the square culvert body 1 is integrally formed with a raised frame 6, located adjacent to the first stopper assembly. A receiving groove 7 is provided at the other end of the square culvert body 1, with the raised frame 6 engaging with the receiving groove 7. When the first stopper rod 3 and first stopper plate 4 of one square culvert body 1 enter the slot 2 of the other square culvert body 1, the raised frame 6 is inserted into the corresponding receiving groove 7.

[0032] A waterproof board (not shown in the figure) is provided at the position where the protruding frame 6 and the receiving groove 7 are connected. The waterproof board is laid inside the square culvert body 1 to improve the waterproof effect.

[0033] In order to further improve the stability of docking, a second limiting assembly is arranged above the first limiting assembly. The second limiting assembly includes a second limiting rod 8 and a second limiting plate 9. The second limiting rod 8 is arranged on the square culvert body 1, and the second limiting plate 9 is fixedly connected to the end of the second limiting rod 8 away from the square culvert body 1.

[0034] The length and width of the second limiting plate 9 are respectively consistent with the length and width of the first limiting plate 4 .

[0035] Specifically, the first limiting rod 3 and the first limiting plate 4 of one square culvert body 1 enter the slot 2 of another square culvert body 1, and the second limiting rod 8 and the second limiting plate 9 simultaneously enter the corresponding slot 2, thereby improving the stability of the splicing of the square culvert bodies 1.

[0036] The outer diameter of the second limiting rod 8 is smaller than that of the first limiting rod 3 , so that there is a certain gap between the outer wall of the second limiting rod 8 and the inner wall of the slot 2 , which is convenient for injecting cement mortar.

[0037] After splicing the two square culvert bodies 1, cement mortar is injected into all the slots 2 through the grouting port 5. After the cement mortar solidifies, the first limiting assembly and the second limiting assembly can be fixed into the slots 2, thereby connecting the two square culvert bodies 1.

[0038] The interior of the square culvert body 1 is provided with a steel bar 11, which can be provided with a mouth shape. The first limiting rod 3 and the second limiting rod 8 are both fixedly connected to the steel bar 11. Before prefabricating the square culvert body 1, the steel bar 11 is placed in the formwork, and then all the first limiting components and the second limiting components are welded together. After pouring concrete, the construction of the square culvert body 1 can be completed. The steel bar 11 can further improve the fixing effect of the first limiting components and the second limiting components on the square culvert body 1.

[0039] Triangular blocks 10 are integrally formed at the four corners of the inner cavity of the square culvert body 1 , and the triangular blocks 10 extend to the convex frame 6 . The provision of the triangular blocks 10 improves the use strength of the square culvert body 1 .
