[0027] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, a corrugated steel box culvert is provided, comprising: a box culvert plate 1.

[0029] Specifically, the box culvert slab 1 includes a box culvert top slab 101, a box culvert bottom slab 102, and a box culvert side slab 103. The box culvert top slab 101, the box culvert bottom slab 102, and the box culvert side slab 103 are connected to each other to form a rectangular structure through connecting components 2. The box culvert slab 1 has a first pad 3, a second pad 4, and a corrugated steel plate 5. The corrugated steel plate 5 is disposed between the first pad 3 and the second pad 4. The ends of the first pad 3 and the second pad 4 facing the corrugated steel plate 5 have mating surfaces that fit against the surface of the corrugated steel plate 5. The first pad 3, the second pad 4, and the corrugated steel plate 5 are fixedly connected by fasteners 6.

[0030] In this embodiment, as Figure 1 and Figure 5 As shown, the box culvert slab 1 includes a box culvert top slab 101, a box culvert bottom slab 102, and a box culvert side slab 103. The box culvert top slab 101 and the box culvert bottom slab 102 are arranged parallel to each other at intervals. The box culvert side slab 103 is arranged on both sides of the box culvert top slab 101 and the box culvert bottom slab 102. The upper and lower ends of the box culvert side slab 103 are fixedly connected to the box culvert top slab 101 and the box culvert bottom slab 102 respectively through connecting components 2. The box culvert top slab 101, the box culvert side slab 103, and the box culvert bottom slab 102 are combined to form a rectangular structure. The box culvert slab 1 is composed of a first pad 3, a second pad 4, and a corrugated steel plate 5. The corrugated steel plate 5 is placed between the first pad 3 and the second pad 4. The lower end face of the first pad 3 and the upper end face of the second pad 4 are mating surfaces that match the surface of the corrugated steel plate 5. The mating surfaces are corrugated. The first pad 3, the second pad 4, and the corrugated steel plate 5 are detachable structures. The first pad 3, the second pad 4, and the corrugated steel plate 5 can be fixedly connected by fasteners 6. The first pad 3, the second pad 4, and the corrugated steel plate 5 can be transported to the construction site for assembly.

[0031] It should be noted that by using a prefabricated structure to build the box culvert, the box culvert slab 1 can be transported to the construction site for on-site assembly, avoiding the pouring and hoisting processes, effectively improving construction efficiency and further saving construction time. At the same time, the corrugated steel plate 5 also has the characteristics of high out-of-plane stiffness, strong compressive and bending resistance, longer service life and better load-bearing capacity.

[0032] In one embodiment, the soil-facing side of the box culvert 1 is provided with a waterproof structure.

[0033] In this embodiment, as Figure 1 As shown, the upper side of the top slab 101 of the box culvert is the soil-facing side, the lower side of the bottom slab 102 of the box culvert is the soil-facing side, the left side of the left side slab 103 of the box culvert is the soil-facing side, and the right side of the right side slab 103 of the box culvert is the soil-facing side. A waterproof structure is laid on the soil-facing side of the box culvert slab 1. The waterproof structure (not shown) can prevent moisture in the soil from penetrating into the box culvert slab 1, avoiding the impact of moisture on the overall stability of the box culvert structure. Preferably, the waterproof structure is tar paper.

[0034] In one embodiment, the connecting component 2 includes a first connector 201, which is disposed at the four corners of the rectangular structure.
