Large Diameter PC Engineering Piles Test in Soft Soil Deep Excavation
Taking a deep excavation project in the soft soil area of Shanghai as the background,the application of large-diameter PC construction method combined steel pipe piles in deep excavation in the soft soil area of Shanghai was understood through pile driving and pulling tests using PC construction method.The impact of each stage on adjacent soil was analyzed.The test results show that using ICE high-frequency resonance free hydraulic hammer for large-diameter steel pipe support and extraction is feasible in deep excavation engineering in soft soil areas of Shanghai.The smoothness,bite and soil blockage of the steel pipe piles are good,and there is no large amount of soil during extraction.The impact of extraction on adjacent soil and surrounding environment is within a controllable range.At the same time,suggestions for the construction process and equipment parameters are proposed based on the experiment,which helps to facilitate the smooth implementation of formal construction and effectively protect the surrounding environment.
