预制桩板组合护岸在新沟河延伸拓浚工程中的应用

Application of prefabricated pile-slab combined revetmentin the Xingou River extension dredging project

预制桩板组合护岸是直接用预制桩作为防护、挡土结构的一种护岸型式,可避免土体大开挖。它比传统的直立式护岸性价比高、观赏性强、耐久性好、施工难度小、对周边环境影响少,近些年在河道整治工程中的适用性较为广泛。研究结合预制桩板组合护岸在新沟河工程中的应用阐述其适用条件、优点与缺点、断面特性、稳定验算、设计要点、施工注意事项及扩延设计等主要内容,可供在新治水理念下从事水利工程建设、设计、施工、监理等工作的人员参考。

Prefabricated pile-slab combined revetment is a type of revetment in which prefabricated pile is directly used as protection and retaining structure,which can avoid large excavation of soil.Compared with the traditional upright revetment,prefabricated pile-slab combined revetment was of high cost performance,strong ornamental,good durability,low construction difficulty,and less impact on the surrounding environment,which had been widely applied in river channel regulation projects in recent years.Combined with the application of prefabricated pile-slab revetment in the Xingou River project,the applicable conditions,advantages and disadvantages,section characteristics,stability checking,design points,construction considerations and extension design,etc.,were explained,which could provide reference for those engaged in owner construction,design,constructor construction,and supervision of water conservancy project under new water governance concept.
