医用直线加速器机房超厚混凝土施工要点

Construction Points of Ultra-thick Concrete in the Medical Linear Accelerator Machine Room

结合工程实例,阐述了直线加速器机房混凝土施工的过程,防辐射超厚混凝土施工特点、难点,异型施工缝设置位置选择与处理,预留吊装洞口混凝土封闭浇筑,联合采用几种养护方法,从而保证了超厚混凝土的施工质量,可为类似工程提供借鉴。

With engineering examples,it explains the concrete construction process of the linear accelerator machine room,the characteristics and difficulties of radiation-proof ultra-thick concrete,the position selection and treatment of the special-shaped construction joints,the reserved hoisting hole for closed concrete pouring,and the combined use of several maintenance methods;so as to ensure the construction quality of ultra-thick concrete,and provides reference for similar projects.
