摘要:
目的：城市轨道交通线路的施工时段相对固定，当组织施工维修作业时，办理施工组织必要程序的用时越短，施工时段利用率就越高。为了提升夜间施工时段利用率，确保充足的施工维修作业时间，需对办理施工组织必要程序的用时进行优化控制。方法：结合施工时段利用率的影响因素，对请点、销点、停电、送电、挂地线和拆地线等施工组织必要程序，以及施工组织流程及其组织方式等方面存在的问题进行了梳理和分析，并从优化施工组织方式、精简作业流程、规范作业时间标准和提升设备操作速度等四个方面提出了相应的优化措施，以减少停电类和停电并挂地线类作业的施工组织必要程序用时，提升施工时段利用率。结果及结论：采用上述优化措施对厦门地铁2号线的施工调度系统进行升级改造，对作业人员的操作行为进行规范化要求，对作业时间进行标准化管理后，停电类作业施工时段利用率由81.25%提升至87.92%，停电并挂地线类作业施工时段利用率由72.92%提升至81.25%。所提优化措施对城市轨道交通夜间施工时段利用率的提升效果较好。
Abstracts:
Objective: Urban rail transit lines have relatively fixed operation time periods, the shorter time spent on construction organization essential procedures, the higher construction time period utilization rate in organizing construction maintenance work. To enhance the utilization of night construction period and ensure sufficient time for construction maintenance work, it is necessary to optimize and control time consumption of construction organization essential procedures. Method: Considering the factors influencing the utilization rate of construction time period, problems in construction organization essential procedures such as site application, site clearance, power outage, power supply, wire grounding and dismantling, as well as in construction organization process and organization modes, are sorted and analyzed. Optimization measures are proposed from four aspects correspondingly, including optimizing construction organization modes, streamlining work process, standardizing work time criteria, and improving equipment operation speed, in order to reduce the time required for power outage work and power outage combined with wire grounding work in construction organization essential procedures, ultimately increasing the utilization rate of construction periods. Result & Conclusion: The abovementioned optimization measures are applied to upgrade and transform the construction dispatching system of Xiamen Metro Line 2, and standardization requirements are implemented for personnel operation behavior. After introducing standardized management of work time, the utilization rate of construction time periods for power outage work increases from 81.25% to 87.92%, and for power outage combined with wire grounding work, it increases from 72.92% to 81.25%. The proposed optimization measures demonstrate good improvement effects of urban rail transit night construction time period utilization rate.
