摘　　要：江都区红旗河(波庄河~通江闸段)整治工程位于通南高沙土区,河道驳岸采用装配式桩板结构型式,为确保后续施工质量满足要求,通过试桩获取施工数据,经过对比高压水冲一次性沉桩至设计标高和高压水冲+最后1m振动沉桩两种施工工艺的施工观测与试验检测数据,确定采用高压水冲一次性沉桩至设计标高的沉桩工艺可满足设计要求,并在施工过程中根据地质条件、桩的尺寸等选择适宜的施工设备。The regulation project of Hongqi River(from Bozhuang River to Tongjiang Sluice Section)in Jiangdu District is located in Tongnan high sandy soil area.The riverway revetment adopts the prefabricated pile plate structure.In order to ensure that the subsequent construction quality meets the requirements,the construction data is obtained through pile testing.After comparing the construction observation and test data of the two construction processes of one-time pile sinking to the design elevation by high pressure water jet and the last 1m vibration pile sinking by high pressure water jet,the pile sinking process of using high pressure water flushing for one-time sinking to the design elevation can meet the design requirements,and suitable construction equipment should be selected based on geological conditions,pile size,and other factors during the formal construction process.
