摘要
信号机房施工包括大量线缆布放和焊线工艺,在既有线改造工程、海外工程、恶劣环境工程施工往往面临工期紧、用工难、物资匮乏、施工环境差等施工难题。对信号机房施工制约因素进行分析,通过传统施工模式与工厂化施工模式进行对比,直观介绍信号机房施工工厂化预制技术的主要技术要点。信号机房施工工厂化预制技术可在不改变既有联锁关系和控制电路的基础上,通过调整组合排布和配线节点,改装机柜设备布线方式,以机柜为单元进行定型生产,在施工现场进行柜间集束化和插接化施工。通过这种模块化、统一化、插接化、集束化的装配式施工,可极大简化施工现场配线、调试工作,有效缩短现场施工工期,从而在低施工成本的同时保障施工安全。
Signal equipment room construction involves a significant amount of cable laying and welding,and often faces such challenges as tight timeline,labor shortage,limited resources and poor construction environment in the case of retrofi tting projects of existing lines,and projects in overseas markets and harsh environments.This paper analyzes the constraining factors in signal equipment room construction,and provides a visual comparison between the traditional construction method and the factory fabrication method to introduce the key technical aspects of the factory prefabrication technology in signal equipment room construction.The factory prefabrication technology for signal equipment room construction adjusts the equipment layout and wiring nodes,modifies the wiring method of cabinet equipment without changing the existing interlocking relationships and control circuits.Thus,it allows standardized production at the factory with cabinet as the basic unit,as well as inter-cabinet construction at the construction site featuring bundling and plug-and-play.The proposed factory fabrication method,which features modularization,standardization,plug-and-play and bundling,can greatly simplifi es the on-site wiring and debugging work,and eff ectively reduce the on-site construction time,to ensure construction safety at low construction costs.
