针对既有电气化铁路接触网改造工程的特点,提出在编制接触网改造工程的企业定额时应考虑增加停送电工作程序、在高压线附近施工降低工效、既有接触网设备对新设备安装产生的影响、相关专业同步作业造成干扰、技术标准的提高增加安装和调整时间、一次性达标增加接触网重复调整量、工序间的停歇时间增加、增加等待第一列列车通过的时间等特殊因素,以便能真实地反映定额项目的人工和施工机械台班消耗量。
Aiming at the characteristics of the reconstruction project of the existing electrified railway OCS, it is suggested that the working procedures of stopping power transmission should be considered in the preparation of the enterprise quota for the reconstruction of the OCS, and the work efficiency should be reduced in the vicinity of the high voltage lines. Affect the related professional work synchronization caused by interference, improve the technical standards to increase the installation and adjustment time, one-time compliance to increase the catenary repeat adjustment, the inter-process stoppage time increased, waiting for the first train to pass the special factors such as time Can truly reflect the quota project labor and construction machinery class consumption.
