北京市轨道交通大兴线采用梯形轨枕轨道所占比例较多,工期较紧,采用人工散铺法施工环节多、功效低,作业过程存在安全隐患,针对现有施工工法的缺点进行试验研究,改进采用机械铺设法施工,提高了梯形轨枕轨道的施工质量和工效,施工进度达75 m/d,对曲线地段的梯形轨道施工工艺进行详细介绍。
Beijing Tram Daxing Trapezoidal rail sleepers with a larger proportion of the track, tight schedule, the use of artificial Disposal many aspects of construction, efficacy is low, there are security risks during the operation, the shortcomings of the existing construction methods for experimental study to improve the The mechanical laying method improves the construction quality and work efficiency of the trapezoidal sleeper rail. The construction schedule reaches 75 m / d, and the trapezoidal rail construction technology in the curved section is introduced in detail.
