摘要
针对桥梁桩基施工中反循环钻成孔技术的场地布置、测量放样、桩位放样、埋设护筒、冲洗浆配比、钻孔、混凝土浇筑等施工工艺和施工方法进行总结和分析,收到了良好的效果,能提升钻孔速度和质量,降低施工成本,值得进一步学习和推广。
According to the construction technology and construction method of reverse circulation drilling technology, such as site layout, survey lofting, stake out, burying casing, ratio of rinsing slurry, drilling construction and cleaning, concrete pouring and so on. It is worthy to be further studied and popularized, which can improve the drilling speed and quality,and reduce the construction cost.
