摘要
由于挖孔桩施工简易、场地要求低、施工速度快、扰动小、设备投入小,挖孔成了山区及市区桥梁桩基的首选施工方法。以青岛市东西快速路(三期)跨铁路段工程桩基挖孔桩施工为例,简述了大直径混凝土护壁挖孔桩在市政工程中的应用。
Because excavation pile construction is simple and easy,the low demand for construction field,construction speed fast,and with little noisy and small input on equipment,excavation pile construction has become a priority construction method in the design of bridge pile foundations in mountain area and city.Taking the cross railway section excavation pile foundation construction in Qingdao east-west expressway(3rd period) as an example,this paper describes the application of large diameter concreter slurry-supported excavation pile construction in municipal construction.
