软横跨接续在营业线过渡施工中的应用

The Application of Headspan Connection in Transition Construction of Operation Line

随着铁路建设的日益加快,营业线改造工程也日趋增多,施工企业在改造施工中面临的困难也越来越大,在重要干线和高速铁路施工中尤为突出。加之我国的铁路运输多为电气化牵引,营业线电气化工程的改造施工更加困难。如何提高接触网过渡施工的速度,缓解与铁路运营之间的矛盾,是当前铁路施工中急需解决的关键问题。介绍了传统的过渡施工方法以及既有软横跨接续施工的新方法,阐述了过渡软横跨接续的条件、质量要求、安全措施及其效果及经济效益。

Because the construction of railway is faster and faster,the reconstruction project of operation lines is also growing more and more,and the difficulties of construction enterprises in the construction are bigger and bigger,especially in the construction of important trunks and high-speed railways in China.Additionally,most of railway transportations in China are rely on electrified traction,so the reconstruction of operation lines＇ electrified projects is more difficult.How to increase the speed of transition construction of contact line and how to ease the contradiction between the construction and the railway operation have become the key problems needing to be solved.This paper introduces the traditional method for transition construction and the new method for existing headspan connection construction,and expounds the conditions,quality requirements,safety measures,effects and economical benefits of headspan connection construction.
