跨越铁路既有线的天桥步履式顶推施工技术

Construction Technology of Walking Type Incremental Launching for Overpass Upper Across Existing Railway Line

在铁路信阳站改扩建工程中,为不影响客运列车的通行,保证跨越铁路既有线的天桥顺利施工,结合实际情况,采用了步履式顶推施工技术。相比拖拉式顶推施工技术,步履式顶推技术更安全可靠,可确保新建天桥的施工安全,确保了信阳站改扩建工程的顺利进行。

In the reconstruction and extension project of Xinyang Railway Station,in order not to affect the passage of trains,but to ensure the smooth construction of overpass upper across existing railway lines,and combined with the actual situation,the walking type incremental launching construction technology is adopted.Compared with the dragging-pushing type incremental launching construction technology,the walking type incremental launching construction technology is more safe and reliable,which can ensure the safe construction of the new overpass and the smooth progress of reconstruction and extension project of Xinyang Railway Station.
