预应力混凝土管桩在自重湿陷性场地的施工要点

摘要

结合预应力混凝土管桩在某自重湿陷性场地的施工实例，阐述了预应力管桩在施工前需做的准备工作，着重对试桩、打桩、定桩位、桩机控制等施工工艺流程及应注意的施工要点进行了论述，为确保工程的质量提供了技术支撑。%Combining with prestressed concrete pipe pile construction example in the dead weight collapsible field,the paper describes the con-struction preparation of prestressed pipe pile,mainly discusses pipe testing,pipe piling,pipe location and pipe machine control and other con-struction procedures and matters needing attention in construction,which has provided technical support for guaranteeing the engineering quality.
