超大面积混凝土整体地面施工质量综合预控技术

Pre-control Technology of Construction Quality of Ultra-large Area Integrated Concrete Floor

结合超大面积混凝土整体地面实际工程特点,采取施工质量预控措施:基层铺设滑动塑料薄膜、跳仓浇筑、后切割分缝技术、钢筋网片断开技术、设置抗裂拉杆等施工技术综合集成应用,正确引导了混凝土在超大面积整体地面工程中能量的自然释放,消除了混凝土裂缝产生的潜在因素,很好地控制了整体地面的施工质量;经实践验证,总结出一整套行之有效的超大面积整体地面施工综合预控技术,可作为同类工程的实践指导和借鉴。

Large area concrete characteristics of the overall ground engineering works, construction quality of pre-control measures taken： sliding plastic film laying grass-roots level, jump pouring, after parting cutting technology, a technical piece of steel mesh, set the bar, such as cracking Construction and Technology integrated application, correctly guide the concrete floor in the large area of the overall project the natural release of energy, eliminating the potential for concrete cracks, good control of the overall construction quality of the ground;-proven, summed up a set of effective Construction of overall surface area of the large integrated pre-control technology, similar projects can be used as guidance and reference for the practice.
