摘要
结合湖北香溪河大桥5#主墩钻孔桩施工,文章对复杂地质条件下的倾斜岩面、大直径、超长钻孔灌注桩的钻机选型、钻孔桩施工工艺及特殊地层施工注意事项进行介绍,以提高其成孔质量,并为类似工程施工提供参考。
Combined with drilled pile construction of main pier 5# of Xiangxi river bridge in Hubei, machine selection for drilled pile with super length and large diameter under complex geological conditions, construction technique and construction attentions in special stratum were introduced to improve drilling quality and provide reference for similar projects construction.
