450m Industrial Trestle: RC Slab Replacement & Wear Protection, Functional Kinematics & Spill Prevention Analysis

Engineering design and field coordination for the full-scale modernization of a 450-meter industrial car trestle at +22.250m elevation. The project addressed structural degradation caused by heavy vehicle traffic and extreme material abrasion within a critical loading corridor. Technical Scope: Structural Audit: Identification and partial replacement of reinforced concrete (RC) floor slabs worn down by operational friction. Spatial Coordination: Design and alignment of new fencing structures within tight existing constraints (Axes 83-94). Wear Protection System: Implementation of a high-durability, low-cost lining system utilizing recycled conveyor belts to protect steel and concrete components. Fastening Optimization: M10x50 bolt layout in a staggered (checkerboard) pattern to ensure vibration resistance and rapid modular replacement. Project Outcomes: Zero-downtime implementation through field-engineered layout adjustments. Significant lifecycle extension of the infrastructure via industrial-grade wear shielding. Section: Functional Kinematics & Spill Prevention Analysis Technical Contribution: Conflict Resolution: Conducted a motion analysis to identify a critical design flaw in the material discharge system. Geometry Optimization: Redesigned the discharge chutes ("pants") by extending them by 200 mm to ensure precise material flow onto the car trestle and prevent spillage onto the reinforced concrete slabs. Physical Constraint Verification: Verified that the existing rim ("burt") and guardrail dimensions would physically prevent unintended material overflow during operation. Maintenance Reduction: The redesign minimizes manual cleanup costs and protects the newly installed infrastructure from premature abrasion.
