摘要
结合彭山县前程路下穿工程钻孔桩-混凝土横抬梁架空既有铁路施工工法的设计,分析了可应用于施工工期较短,且在地下水位较高的情况下不允许进行强降水施工的既有线路加固的施工工法的选择、关键性技术、工序流程等。可以预见,该施工工法将会被广泛地应用于既有铁路增设立交通道的建设中。
Combining the design of Pengshan County Qiancheng Road engineering drilling beneath piles-concrete cross beams overhead lift existing railway construction method, this paper analyzes the can Application in construction period is short, and the existing line reinforcement construction method of choice in high underground water level does not allow for strong precipitation construction, key technologies, process flow and. Predictably, the construction method will be widely used in the construction of existing railway interchange channel in addition.
