摘要
三门核电一期为AP1000核电机组工程,其盾构法取水隧道的设计在我国核电领域尚属首次,且隧道内径达6200mm、垂直顶升立管截面尺寸达2.44m×2.44m、取水构筑物直径达4.5m,均为电力行业取水工程中最大。三门核电一期盾构法大直径取水隧道及垂直顶升法取水的成功运用,为今后电厂取排水工程的设计提供了借鉴。
Sanmen nuclear power station is AP1000 unit project.It＇s the first time to use water-intake shield tunnel in nuclear power station.In the design of Sanmen nuclear power project,the inner diameter of water-intake shield tunnel is 6200mm,the section size of standpipe is 2.44m×2.44m,and the diameter of water-intake hat is 4500mm.Both diameters of the tunnel and the standpipe are largest in power station projects.The successful application of large diameter water-intake tunnel and vertical lifting structure in Sanmen nuclear project can provides valuable reference for the future water-intake project in the power station.
