摘　　要：以慈溪市人民医院行政综合楼工程为例,介绍了挤扩支盘混凝土灌注桩施工工艺。通过工程实践,总结了挤扩支盘桩施工质量和成盘的监控要点。实践证明挤扩支盘桩桩基造价节约27%,工期缩短20%,且节省钢筋等。With the example of the administrative building works in Cixi People's Hospital, the workmanship for construction of the in-situ concrete pile with extruded tray support is introduced hereby, and based on engineering practice, key points are summed up for monitoring the construction quality and tray formation. It is proved in practice that the cost for this new type of pile can be saved by 27%, and that the construction period shortened by 20%, with the consumption of reinforcement reduced.
