顶进框架桥施工道岔加固技术

Turnout Reinforcement Technology for Jacking Frame Bridge Construction

随着我国铁路运输的发展,列车的运行速度不断提高,以及城市规划的不断的完善,在铁路施工完成或开通线路上,增加的城市规划道路的下穿铁路桥,为了城市规划道路的下部实施,在运营铁路下,顶进框架桥对城市规划道路起到重要的意义。本文以新建京张铁路福田北路顶进框架中桥,框架顶进道岔扣轨加固的施工为例,介绍在列车运行的情况下,满足道岔搬动调车的情况下,对咽喉区线路道岔扣轨加固施工的技术分析,以供借鉴。

With the development of China's railway transportation,the speed of trains has been continuously improved,and urban planning has been continuously improved.On the completion of railway construction or the opening of lines,urban planning roads underpassing railway bridges increased.In order to ensure the construction of urban planning roads,under the operating railway,jacking the frame bridge plays an important role in urban planning roads.This article takes the construction of the newly built Futian North Road on the Beijing-Zhangzhou Railway as an example for the construction of a frame bridge and the turnout reinforcement of the turnout of the turnout of the frame,introduces the technical analysis of turnouts rail deduction reinforcement in the throat area when the train is running and the turnout is satisfied,for reference.
