摘要
结合工程实际,对超大直径桩成孔困难、容易垮孔等施工难题进行了攻关。总结了超大直径桩的施工工序、施工流程、桩基检测以及护壁支模、大直径钢筋笼加工、成孔工艺以及垮孔处理等关键施工技术,以期为后续类似项目施工提供参考。
Combined with the actual engineering practice,the construction problems such as difficult pile formation and easy collapse of oversized diameter piles are investigated.The construction process,construction flow,pile foundation inspection and key construction techniques such as retaining wall support,large diameter reinforcement cage processing,borehole formation process and collapsed borehole treatment are summarized to provide references for the subsequent construction of similar projects.
