高强预应力管桩静压法施工在膨胀土地区的应用

The application of high pressure pre-stressed pipe pile static pressure method in expansive soil area

以合肥市某实际项目为例,结合膨胀土性质、地基土构成、机械设备的配置及施工现场的准备工作,从测量放线、桩定位及桩起吊、就位两方面,分析了主要的施工技术措施,并阐述了施工中常见的质量问题及注意事项。

Taking a practical project in Hefei as an example, combining with the nature of expansive soil, foundation soil composition, mechani-cal equipment configuration and construction site preparation work, from the line measurement, pile location and pile lifting, in place two as-pects ,analyzed the main construction technical measures, elaborated the common quality problems and matters needing attention in construction.
