地下综合管廊将核电站厂区的给排水、工艺管线和电缆等集中敷设,不仅能充分利用地下空间,而且可以避免管线施工和维修时反复开挖。文章结合三门核电一期工程综合管廊设计和建造阶段的经验,对AP1000核电站综合管廊加固段设计、接口节点设计以及排水和消防设计进行了阐述,可为类似核电堆型的核电站地下综合管廊提供设计参考。
The underground integrated pipe network concentrates the water supply and drainage, process pipelines and cables of the nuclear power plant’s factory area, and can not only make full use of the underground space, but also avoid repeated excavation during pipeline construction and maintenance. Combining with the experience of the design and construction stage of Sanmen NPP Phase I project, this paper elaborates the design, interface design, drainage and fire protection design of the integrated corridor of AP1000 nuclear power station, which can be underground synthesis of nuclear power plant similar to nuclear reactor Gallery provides design reference.
