直线加速室超厚墙体施工技术

Construction Technology for Ultra-Thick Wall of Linear Accelerating Room

医院直线加速室对墙体和顶板具有很高的抗辐射要求,若采用常规的铅板墙面或重型混凝土手段,施工和建设成本非常高。结合工程实际,通过采用优化施工缝设计、改进墙体加固措施、超厚墙体混凝土施工自动降温等创新技术,成功地抑制了超厚混凝土墙体的裂缝发生,使普通混凝土也达到了抗辐射要求,可为类似工程提供借鉴。

The hospital linear accelerating room has high radiation resistance requirements for the wall and the ceiling, and the construction and capital cost are very high if the conventional lead-plate wall or heavy-duty concrete means are used. Combining with the engineering practice, through the use of innovative construction techniques such as optimizing the design of construction joints, improving the reinforcement measures of the walls and automatically cooling of concrete construction of super-thick wall, etc., the cracks in the super-thick concrete walls are successfully suppressed and the ordinary concrete can meet the anti-radiation requirement, and can provide references for similar projects.
