AI Technical Summary
The existing culvert connection points pose safety hazards and have poor structural stability, especially when the arched main body and the bottom plate form a right-angle connection, resulting in severe stress concentration.
The closed box culvert structure is adopted, including a bottom plate, connecting structure and arched box culvert body. A stable connection is formed by installing upright plates on both sides of the bottom plate and pouring concrete. Fasteners are used to fix the box culvert body to avoid right angle connections. Corrugated steel plates are used to improve stability.
This eliminated stress concentration at the connection points, enhanced the stability and safety of the culvert, and improved the overall load-bearing capacity and strength of the structure.
