Abstract
The analysis of the construction diversion structures in the construction of the gravity dam at the reservoir hub is the central content of the construction planning and organization of the reservoir hub project.It constitutes an important guarantee for the compliance of the construction of the reservoir hub project and has important engineering significance for the construction quality management of gravity dam reservoir project.Therefore,a practical study is conducted on the construction technology analysis of diversion structures for the construction of the Hanjiang Gaopi Gravity Dam Reservoir Hub Project in Dapu County.The results show that,understanding the project overview,first of all,an analysis of the construction diversion plan for the gravity dam at the reservoir hub is carried out,focusing on construction procedures,timing,diversion periods,and flow rates.At the same time,the analysis of construction technology for diversion structures in the construction of gravity dam reservoir hub projects is emphasized around the diversion building layout and type(mainly including the right bank expansion and riverbed protection measures,cofferdam type,cofferdam foundation seepage prevention measures,longitudinal cofferdam foundation treatment,cofferdam erosion protection measures and protection measures for the left bank riverbed in the second phase,etc.),diversion engineering construction(mainly including the right bank riverbed expansion excavation construction,diversion riverbed protection engineering construction,cofferdam construction and cofferdam demolition,etc.),closure(mainly including aspects of closure design standard,closure way of selection,calculation results and closure construction).It can provide reference for the construction technology analysis of diversion building in gravity dam project of similar reservoir hub.关键词
