医用直线加速器室现浇大体积混凝土施工技术

Construction Technology of Cast-in-situ Mass Concrete in Medical Linear Accelerator Room

在贺州市人民医院直线加速器室现浇钢筋混凝土结构施工中,对超厚墙板、顶板的高大模板施工制定对拉螺栓、钢管支撑的技术方案,指出大体积混凝土浇捣分为底板、墙板与顶板两段施工,并注意施工防裂,达到防辐射的效果。重点介绍了底板、墙板与顶板混凝土施工工艺,指出通过布置测温点的方式对大体积混凝土施工过程进行温度监控,以防止裂缝产生。

During the construction of linear accelerator room in Hezhou City People＇s Hospital,technical plan of split bolt and steel pipe support is made for super-thick wallboard and roof.Furthermore,it is indicated that floor,wallboard and roof are divided into two segments for mass concrete pouring,and crack prevention methods should be applied to ensure the effect of radiation protection.The construction technologies for concrete pouring of floor,wallboard and roof are introduced in detail,and temperature monitoring points are set to prevent cracks.
