工程概况
2. General
台山核电站一期工程HGU管沟是连接循环水虹吸井(HCA)与重要厂用水泵房(HPA/C)专设的重要冷却水管沟。采用核岛反应堆坐标系(坐标以1980西安坐标系为准),反应堆厂房标高±(国家85高程系),所有标高都以反应堆厂房的相对标高为准;×,×,侧壁及底板、顶板均为500mm厚的现浇钢筋混凝土结构;结构需进行找坡,%、%%。HGU管沟替代砼及垫层采用C25砼,主体结构采用欧标C35/45砼;管沟共计10段(060~069段)。
In Taishan Nuclear Power Station project(Phase 1), HGU is essential cooling water pipeway which is dedicated to link the recycled water siphon well(HCA) and essential service pump station(HPA/C). Coordinate system of Nuclear Island reactor is applied(XI AN Coordinate System 1980). Level ± of reactor building corresponds to of National Elevation Datum 1985. All levels relate to the reference level of reactor building. The outside section of HGU is largely square hole of ×3
