| Abstract: | 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. |
