摘要
结合武汉绿地中心桩基工程具有桩径大、钻孔深、嵌岩深等特点,采用旋挖+冲击反循环接力的施工工艺,充分发挥各钻机的优势,提高了嵌岩施工效率;并对岩层钻进过程中的泥浆性能进行了分析调配,确定最佳钻进效率时的泥浆密度、黏度。施工结果表明,桩的施工质量满足要求,效果明显。
The rotary digging and pounding back cycling relay construction technology has been applied in piles engineering of Wuhan Greenland Center to develop the advantages of the various drilling machines and improve the rock-socketed pile construction productivity,based on the characteristics of big diameter,deep drilling and deep rock-socketed of the piles. The mud characteristics in the drilling process in the rock are analyzed and allocated to ascertain the optimal mud specific weight and viscosity. The construction results show that the pile construction quality meets the requirement,and the productivity is improved obviously.
