摘要
密实砂层中的静力触探和标准贯入试验表明,将PHC管桩静力压入砂层地基中极为困难。郑州市某住宅工程中,经方案比选采用大密度泥浆护壁预引孔静压沉桩技术,经检测管桩各项技术指标满足设计要求。
After static sounding and standard penetration tests of compacted sand stratum, it is very difficult to insert PHC tubular pile into the foundation of sand stratum by using static pressure. After comparison among schemes, static pressure pile sinking technique in preliminary guiding hole with high-density slurry breast wall is used in a residential community engineering in Zhengzhou. After inspection, all technical indexes of the tubular pile satisfy the design requirements.
