摘要
郑集河输水扩大工程既是南水北调东线一期配套工程,又是提高江苏省徐州市南四湖湖西地区水资源保障水平、解决湖西地区严重缺水问题、保护湖西地区生态红线的关键工程。工程在拓浚河槽时,为减少扩挖占地,采取板桩结构型式,阐述了板桩护岸设计、板桩沉桩施工方法、桩间连接处理措施等。预制桩护岸在水利工程中,特别是在地质相对复杂、施工工期短的地区应用相对较少,本工程板桩设计成果可为类似地区河道建设提供参考。
Being the counterpart scheme of phase-Ⅰ of the Eastern Route of South-to-North Water Diversion Project,the expansion of the Zhengji River Water Diversion Project is crucial for safeguarding water supply, alleviating water shortage and protecting river channels from ecological degradation in the Huxi Area. In order to save land, the technology of sheet pile structure is adopted during the dredging of the channel. Descriptions are given to the design of sheet pile revetment, the construction method of sheet pile sinking and treatment measures of connection between piles.Precast pile revetment is rarely used in water diversion projects, especially in the area that has relatively complicated geological conditions and short construction periods of the project. Its design may be applied to other areas.
