1工程概况本工程为电力除灰工程,位于某发电厂厂内,为特构工程,由三个直径为12.6米圆形连体筒仓组成,总高度为36.2米。主体筒壁为钢筋砼结构,标高为11.500米以下筒壁厚为400mm,标高为11.500米以上筒壁厚为300mm,筒壁砼强度等级为C30,钢筋为HPB235、HRB335,筒壁为双层配筋。其构筑设计外墙部分为清水混凝土,成型后的混凝土表面不作任何修饰,以混凝土自然状态为饰面的混凝土,强调混凝土的自然表现机理。
1 Project Overview The project is a power ash removal project, located in a power plant, a special structure project, consists of three 12.6-meter diameter circular Siamese silos with a total height of 36.2 meters. The main cylinder wall is reinforced concrete structure, the elevation is 11.500 meters below the cylinder wall thickness of 400mm, the elevation of 11.500 meters above the cylinder wall thickness of 300mm, the concrete wall strength grade C30, reinforced to HPB235, HRB335, cylinder wall is double layer Ribs. The exterior part of the building is designed as clear water concrete, the surface of the concrete after molding is not modified, and the natural state of the concrete is the concrete facing the concrete. The natural performance mechanism of the concrete is emphasized.
