“码槽法”施工在铁路涵洞改造中的应用

＂Code Process＂ construction for railway culvert reconstruction

煤五期翻车机房工程位于秦皇岛港煤三、煤四期翻车机房铁路环线之内，施工通道是制约翻车机房施工的关键问题。经反复研究，决定对既有线铁路涵洞进行净空拓深改造，以解决大型施工机械和工程车辆无法通行的问题。为此提出了“码槽法”改造方案，将设计方案报请铁路设计单位复核，并对涵洞实施了改造。对“码槽法”改造方案及施工要点进行介绍，供同类工程参考。

The phase Ⅴ coal dumper is located within the railway loop of Qinhuangdao Phase Ⅳ dumper and Phase m dumper, and the construction channel is the key restrictive factor for the dumper construction. After careful studies, we decided to carry out deepening of the existing railroad culvert to expand the clearance so that large-scale construction machinery and engineering vehicles could pass through. We proposed a ＂code process＂ scheme, which is expounded in this paper.
