提高封锁天窗利用率 实现施工和运输双赢

Improve the Utilization Ratio of Maintenance Gap, Achieve Dual Benefit of Construction and Transportation

大型养路机械利用封锁天窗进行施工时,由于比人工作业时所需要的准备作业时间和施工后的整理作业时间长,使正常施工作业时间缩短,因此需要延长天窗时间。沪宁线上行自2002年4月起,开设了210min的天窗,作业效率增加了300%。为增加单位天窗施工时间和减少对开行列车的影响,在繁忙区段应尽量安排晚间施工,以实现施工和运输双赢。

When large permanent way equipment is in operation dur-ing maintenance gap, because it will take longer for the preparationand the clearing up than by labor work, there will be a need for ex-tending maintenance gap. Since April 2002, a maintenance gap of 210minutes was set for Hu-Ning Line, leading to an increase of 300% inwork efficiency. To increase the time for unit maintenance gap and tolower the impact to train operation, we should try to carry out construc-tion work at night for the busy sections so as to achieve dual benefit ofconstruction and transportation.
