Bridge pile foundation composite construction method under complex geological conditions
A bridge pile foundation composite construction method under complex geological conditions comprises the following steps: S1, after a site is leveled and compacted, conducting pile position lofting; S2, burying a pile casing; S3, installing the percussion drill in place, and starting drilling after centering; S4, drilling to a sandstone layer, moving away the percussion drill, installing the rotary drilling rig in place, and centering; S5, enabling the rotary drilling rig to drill, and conducting acceptance check after hole forming; S6, after the holes are cleaned for the first time, installing a reinforcement cage and a guide pipe; S7, after the hole is cleaned for the second time, pouring underwater concrete, and manufacturing a concrete test block. According to the method, impact hole forming is adopted in the clay stratum and the pebble stratum, the construction efficiency is guaranteed, the stability of the pile wall is guaranteed, rotary drilling is adopted in the rock stratum, the construction efficiency is guaranteed, the hole forming effect is guaranteed, through combined application of the two hole forming methods, the pile foundation construction efficiency is greatly improved, and the construction cost is saved.
一种复杂地质条件下桥梁桩基复合施工方法，包括以下步骤：S1：对场地平整压实后，进行桩位放样；S2：埋设护筒；S3：冲击钻机安装就位，对中后开始钻探；S4：钻探至砂岩层，移开冲击钻机，旋挖钻机安装就位，对中；S5：旋挖钻机钻进、成孔后进行验收；S6：第一次清孔后，安装钢筋笼和导管；S7：第二次清孔后，灌注水下砼，制作砼试块，本发明在粘土地层和卵石地层中采用冲击成孔，既保证了施工效率又保证了桩壁的稳定，在岩石地层采用旋挖钻孔，既保证了施工效率又保证了成孔效果，通过两种成孔方法的联合应用，大大提高了桩基施工效率，节约了施工成本。
