摘要
在三沪输变电工程华新站防火墙的施工过程中,为了控制施工工艺,采取了一些措施,使外露混凝土达到清水混凝土标准。通过对模板刚度、表面涂塑厚度的控制及混凝土表面气孔的清除等措施达到了混凝土表面的平整度、光洁度;通过严格保证水泥、砂、石子的来源及质量,保证了清水混凝土表面的色泽一致;同时加强了后期养护,使得防火墙的施工达到了预期目的。
During Huaxin station fire-wall construction in Sanhu power transmission and distribution project, to control construction technology, certain measures have been adopted in exterior concrete construction to reach as-cast finish standard. Through controlling stiffness of the formwork and thickness of surface coating, as well as eliminating surface pores, a level and fine finish is reached. Through strict origin and quality control of concrete, sand and gravel, a consistent color of the as-cast finish concrete surface is achieved. In the mean time, construction of the fire-wall reached original goal through careful post-curing.
