核电站钢穹顶高精度异型拼装场地处理与实施

Treatment and Implementation of High-precision Special-shaped Assembly Site for Steel Dome of Nuclear Power Plant

核电站核岛钢衬里穹顶高精度异型拼装场地形成成套技术,在有限的场地范围及工期内,采用钢筋混凝土和钢结构平台相结合的方式,克服了施工区域地形复杂、平面高低不一、平整度及承载力要求高、工期严峻的客观条件,使得穹顶拼装场地如期完成。

The high-precision special-shaped assembly site formation technology for nuclear island steel lining dome of nuclear power plant is applied.In the limited site scope and construction period,the combined method of reinforced concrete and steel structure platform overcomes the objective conditions of complex terrain,uneven plane height,high flatness and bearing capacity,and severe construction period in the construction area,making the dome assembly the venue completed as scheduled.
