Embodiment 1
[0033] see figure 1 The corrugated steel box culvert structure includes four jigsaw units. In this embodiment, each jigsaw unit includes a steel corrugated board 11;
[0034] The panel unit is divided into upper horizontal panel 1, lower horizontal panel 2 and longitudinal panel 3. The two ends of the upper horizontal panel 1 are provided with downwardly extending installation short edges 4, and the two ends of the lower horizontal panel 2 are provided with upward The extended installation short edge 4, two longitudinal panels 3 are arranged between the upper horizontal panel 1 and the lower horizontal panel 2, and in the installation short edges 4 on both sides of the upper horizontal panel 1 and the lower horizontal panel 2, four The block jigsaw unit is fixed by installing the short edge 4 to form a box structure, and the four inner corners of the box structure are fixed after being closely attached to the corrugated steel angle steel structure 6.

Embodiment 2
[0037] In this embodiment, the single panel unit is formed by connecting multiple steel corrugated plates 11. Specifically, flange plates are arranged around the steel corrugated plates 11, and the multiple steel corrugated plates 11 are connected or welded by flange plates and bolts. In one piece, the steel corrugated plate 11 at the end does not have a flange plate, which is used for inserting and fixing.
[0038] see figure 2 , the connector between the jigsaw units is a slotted connector, including a connector body 7, a corrugated groove 701 is provided on the horizontal side and the vertical side of the connector body 7, and the corrugation of the connector body 7 The position of the body embedding groove 701 is provided with multiple groups of connecting holes 702, and the end of the steel corrugated plate 11 of the jigsaw unit is provided with installation holes. In this embodiment, four puzzle units and four sets of connector bodies 7 can be spliced and fixed to fo...
Embodiment 3
[0041] see Figure 3-Figure 5 , the connectors between the jigsaw units are split-type socket-type connectors, including inner mold 8 and outer mold 9 with a right-angle structure, and the upper end of inner mold 8 and the lower end of outer mold 9 cooperate to form a corrugated body groove 701 , the inner mold 8 and the outer mold 9 are provided with a plurality of sets of connection holes 702, and the end of the steel corrugated plate 11 of the jigsaw unit is provided with installation holes, and the steel corrugated plate 11 of the jigsaw unit is inserted into the corrugated groove 701 and connected with the inner by bolts. Die 8 and outer mold 9 are connected to form the overall structure of the box body.
[0042] In this embodiment, both the inner mold 8 and the outer mold 9 are thick right-angle casting structures, which are prefabricated according to the corrugated steel plate 11, and have extremely strong mechanical strength. The upper end surface of the inner mold 8 i...
