近年来,由于轻便高效真空设备和软吸垫的研制成功,水平面混凝土的真空作业在土建部门已逐步推广,但在大斜面和直立面混凝土的浇筑中还很少应用。宜兴县横山水库溢洪道扩建工程中,采用了真空翻模施工工艺。实践表明,在大斜面混凝土浇筑中,采用真空翻模施工技术,可以缩短混凝土养护和拆模时间,加速模板周转,显著提高混凝土强度,降低工程造价。现就横山水库消
In recent years, due to the successful development of lightweight and efficient vacuum equipment and soft suction pads, the vacuum operation of horizontal concrete has been gradually popularized in the civil engineering department, but it is seldom used in the pouring of large inclined and vertical concrete. Yixing County Hengshan reservoir spillway expansion project, the use of a vacuum turn mode construction technology. Practice shows that in large inclined concrete pouring, the use of vacuum overturning construction technology can shorten the concrete curing and demolition time, speed up the template turnover, significantly increase the strength of concrete and reduce project cost. Hengshan Reservoir now disappear
