Key points for assembling corrugated panels for bridge culverts: Design construction procedures for assembling corrugated panels in sheets, organizing the sequence of panels rationally, designing board sizes that are convenient for transportation and installation while minimizing the number of bolts; aim to position connections away from areas of equivalent and tangential stress concentration; control tangential stress by adjusting bolt shear stress.2Bridge Reinforcement Corrugated Pipe Assembly Precautions: First, prepare installation tools, simple lifting equipment, sleeve wrench, torque-tightening electric wrench, torque-tightening wrench, ensure enough scaffolding, planks, and power supply at the construction site. Pre-installation tasks: Check the elevation and longitudinal slope of the steel corrugated pipe culvert bottom; determine the position, central axis, and midpoint of the corrugated pipe. Assemble the bottom steel corrugated plate: Use the central axis midpoint as the benchmark, locate the first corrugated plate, and extend from this point to both ends. The overlap length is50mmFor the connecting holes, the bolts are inserted from the inside to the outside, with a washer placed on the outer side before screwing on the nut. The nut is pre-tightened using a specific impact wrench socket wrench. Assembly of the arch-shaped steel corrugated pipe: assembled sequentially from bottom to top; the circumferential connection uses a stepped design, with a lap length of:50mmThe connection overlap between the top two panels is misaligned with the bottom two. After aligning the connection holes, insert bolts from the inside out into the holes, and pre-tighten the nuts using a special wind gun socket wrench. As the circumferential assembly is joined to the circular ring, measure the cross-sectional dimensions and adjust the pre-tightened bolts promptly to correct the assembled top corrugated plate, ensuring the cross-sectional dimensions meet the requirements.

The reinforced corrugated box culvert structure comprises multiple panel units, with the multi-faceted panel units vertically connected in sequence through connecting elements to form a closed box culvert. This includes top, bottom, left, and right panel units, which feature steel corrugated plates, reinforcing pipes, and fixed cross plates. The reinforcing pipes are positioned within the valleys of the steel corrugated plates, with adjacent reinforcing pipes on abutting panel units meeting perpendicularly. All the reinforcing pipes form an internal reinforcing frame in the shape of the box culvert, while several fixed cross plates are horizontally secured to the inner wall of the steel corrugated plates to stabilize the reinforcing pipes.
9.Furthermore, the aforementioned single-sided plywood unit includes multiple steel corrugated panels, with the valleys of the corrugations along the edges of the panels aligned and then connected or welded together into sheets using bolts.
10.Additionally, bolt holes are provided on the peaks of the steel corrugated plates within the said panel unit. Multiple parallel fixed cross plates reinforce the pipe clip by pressing it into the troughs of the steel corrugated plates and securely fasten them with high-strength bolts.
