摘要
通过采用反循环钻孔灌注桩施工工艺,确定合理的钻速、泥浆密度等参数,并结合施工过程钢筋笼工艺的改进,有效解决了在流塑状高压缩淤泥质土层中采用传统工艺进行灌注桩施工所遇到的难题,高质量完成了桩基施工。
By adopting the reverse circulation construction of bored pile construction technique to determine a reasonable penetration rate,mud density and other parameters,and combining with the steel cage construction process improvement,the problems encountered in the traditional technology of bored pile construction in the flow of plastic-like highly compressive muddy soil were solved effectively and pile construction was completed with a high quality.
