线上移动式接触焊施工技术及费用分析

Technique and Cost Analysis of Linearly Movable Contact-weld

介绍了我国内地城市轨道交通工程中首次采用的线上移动式接触焊施工技术。结合广州地铁 2号线施工监理实践 ,对线上移动式接触焊工法和传统的临时基地固定式接触焊工法进行了方案比较和费用分析比较 ,指出线上移动式接触焊工法具有工效高、费用低、施工组织灵活等突出优点 ,值得大力推广 ,同时对完善该工法的技术细节和质量控制标准提出了建议。

With an introduction of the technology of linearly movable contact-weld adopted in Urban Mass Transit,the author compares linearly movable contact-weld with temporary base fixing contact-weld on the experience gained in Guangzhou Metro Line 2,and points out that linearly movable contact-weld has higher efficiency,lower expense and is convenient in construction.He also argues that for the use in a wider field,the technology details and controu quality standard shall be further improved.
