铁路既有线顶进施工是在保证铁路行车不中断的前提下,通过对既有线加固后,在既有线路基一侧开挖工作坑,浇筑滑板,在滑板面上设置润滑隔离层,然后在滑板上预制钢筋混凝土框架及修筑后背,安装顶进设备,通过传力设备,借助与后背的反作用力把框架向前推进,当顶进一个顶程后,再增加顶铁,挖运出土一个顶程距离,继续进行下一个顶程施工,如此循环,直至箱涵顶进就位为止。
鐵路既有線頂進施工是在保證鐵路行車不中斷的前提下,通過對既有線加固後,在既有線路基一側開挖工作坑,澆築滑闆,在滑闆麵上設置潤滑隔離層,然後在滑闆上預製鋼觔混凝土框架及脩築後揹,安裝頂進設備,通過傳力設備,藉助與後揹的反作用力把框架嚮前推進,噹頂進一箇頂程後,再增加頂鐵,挖運齣土一箇頂程距離,繼續進行下一箇頂程施工,如此循環,直至箱涵頂進就位為止。

Railway jacking construction is the premise to guarantee the railway is not interrupted, based on existing reinforced, under the existing line side of the base excavation pit, pouring skateboard, lubrication isolation layer on the slide surface, and then slides on the precast reinforced concrete frame and build back, mounting jacking equipment, through the force transmission equipment, with the help of and reaction to the frame back to move forward, the top into a top program, add top iron, dug unearthed a top distance, to continue the top construction process, under such a cycle, until the box culvert jacking in place.
