阐析高速铁路接触网施工工艺与作业指导书

我国电气化铁路建设从普速发展到高速，就接触网系统来说，设计和施工技术经历了3个阶段的质量提升，上了3个台阶，为施工技术达到国际一流水平奠定了基础。这都是由符合工程特点的施工工法、工艺及作业指导书作保障实现的。但在此前几年的高速铁路接触网施工中了解到，各施工单位编写的或执行的施工工艺及作业指导书，其工程分类和应包括的项目及内容不但不统一，而且有较大的差别，以致造成施工质量和精度不能保持在一个较高的水平上。为此结合高速铁路接触网设计对其施工工艺及作业指导书进行进一步阐析。

Analysis of High Speed Railway Catenary Construction Process and Work Instruction

Our country electrification railway construction has developed from normal speed to high speed. For cate- nary system, the design and construction technology have experienced three stages of quality improvement and laid a foundation for achieving the international first - class level, which is performed under the guar- antee of the construction methods, process and work instruction with the requirements of project charac- teristics. But in previous years of high speed railway catenary construction, the project classification and project content of construction technology and operation instruction are different, so that the construction quality and accuracy can not keep in a higher level. Therefore, this paper discussed the construction process and work instruction combined with high speed railway catenary design.
