摘要
为更好的控制近接高铁线路工程施工期间的风险,基于人工挖孔桩的D型便梁加固技术在近接高铁线路施工中逐步应用,并取得了良好的效果。为进一步在类似工程中推广D型便梁,文章以莆田火车站南北广场东西两侧地下通道涉铁工程为例,阐述基于人工挖孔桩的D型便梁加固原理、工艺流程、应用效果,以期后续同类型工程提供参考。
In order to better control the risk during the construction of the proximity high-speed railway line,the D-type beam reinforcement technology based on manual excavation pile has been gradually applied in the construction,and good results have been achieved.In order to further popularize D-type beams in similar projects,the article takes the railway-related projects of the Putian Railway Station as an example,and expounds the reinforcement principle,technological process and application effect of D-type beams based on manual excavation piles,so as to provide reference for subsequent projects of the same type.
