信号工程改造施工关键技术研究与实践
Research and Practice on Key Technologies for Retrofitting Construction of Signaling Projects
摘要
Abstract
This paper examines the signaling system retrofitting project at a major hub station through a case study.Leveraging multi-disciplinary theories such engineering geology,engineering management,and signaling systems engineering,it systematically analyzes the intrinsic mechanisms of five core technical challenges encountered during the retrofitting process:pre-buried conduit conflicts,high-risk cable operations,constrained outdoor equipment installation,complex indoor wirings together with frequent software upgrades,and construction quality control.To address these challenges,innovative technical countermeasures are proposed,integrating Building Information Modeling(BIM)technology,material mechanics,and collaborative management theory.These countermeasures include geological-condition adapted optimization,full-process refined cable management,and synchronized track-panel installation techniques.The effectiveness of these solutions is quantitatively analyzed through theoretical validation and engineering practice(e.g.,by demonstrating the increase of pre-buried conduit installation efficiency by 25％and the reduction of cable sheath damage rate to 0％).Furthermore,this research establishes a systematic"Survey-Design-Build-Verify"four-stage system methodology.This framework addresses the theoretical gap in refined management for signaling system retrofitting projects under train operation scenarios.It serves as both an academic reference and a practical paradigm for similar projects,contributing significantly to advancing the academic rigor and systematic approach of engineering practices for railway signaling in China.关键词
