摘要
静态泥浆护壁旋挖成孔工艺是一项先进的成孔工艺。较传统的循环钻机或冲击钻机而言,具有施工周期短、费用较低、施工质量容易保证等优点,文中以山西太祁高速公路晋祠高架桥主桥桩基础施工为例,介绍了旋挖钻机施工桩基础的施工工艺。
The method of rotary drilling hole and protecting hole wall by static mud is an advanced technique to drill hole.It has several advantages such as short construction period,cheap construction cost and easily ensuring construting of main pile foundation of Jinci Bridge in Taichi Superhighway as an example,the construction technique of this method is put forward.
