Development and Optimization of a Recyclable Non-Embedded Support System for Thermal Pipeline Trenches in Urban Environments.

Existing support systems for thermal pipeline trenches often fail to meet the specific needs of narrow strips, tight timelines, and short construction periods in urban environments. This study introduces a novel recyclable, non-embedded support system composed of corrugated steel plates, retractable horizontal braces, angle steel, and high-strength bolts designed to address these challenges. The system's effectiveness was validated through prototype testing and optimized using Abaqus finite element simulations.
