[0003] Since prefabricated box culverts are in a spliced form and are often buried in soil layers, water inside the box culverts is likely to flow out from the splicing seams, thus causing leakage of the prefabricated box culverts. Summary of the Utility Model

[0033] As Figure 1 and Figure 2As shown in the figure, each set of connecting devices 3 includes a first precast slab 31 and a second precast slab 32 precast at opposite ends of two adjacent culvert bodies 1 respectively; a plug board 33 is fixedly connected to one side of the first precast slab 31, a slot 321 is formed on one side of the second precast slab 32, the plug board 33 is inserted into the slot 321, and a fixing mechanism 4 for fixing the plug board 33 is installed in the slot 321. When the two adjacent culvert bodies 1 are connected by moving the culvert body 1, at this time the plug board 33 is inserted into the slot 321, and then the plug board 33 is fixed by the fixing mechanism 4, so that the two culvert bodies 1 can be fixedly connected; in summary, the provided connecting device 3 facilitates the fixed connection of the two culvert bodies 1.
