Maintenance method for super-thick irregular concrete roof of medical linear accelerator chamber
The invention provides a curing method for an ultra-thick irregular concrete top plate of a medical linear accelerator chamber, and belongs to the technical field of mass concrete structure construction. When top plate pouring enters the tail, a 1.5 m-thick top plate is firstly poured, and at the moment, a 3 m-thick part of the top plate is about to begin to be subjected to suspended formwork pouring. The top plate with the thickness of 1.5 m firstly enters the maintenance stage and needs to be well protected. And after the top plate with the thickness of 3m is poured, the side surface is different from the top surface and is maintained with a mold. Maintenance takes geotextile moisture preservation and cotton cloth heat preservation as basic methods, and different treatment methods for different thicknesses, top surfaces and suspended formwork parts are formed. According to the invention, concrete at different development stages and under different exposure conditions can be maintained in place at one time, and concrete cracking is avoided.
本发明提供一种医用直线加速器室超厚不规则混凝土顶板养护方法，属于大体积混凝土结构施工技术领域，本发明在顶板浇筑进入尾声时，1.5m厚顶板先浇筑完成，此时3m厚部分顶板即将开始吊模浇筑。1.5m厚顶板先进入养护阶段，并需做好保护。3m厚顶板浇筑完成后，其侧面不同于顶面，为带模养护。养护以土工布保湿、棉布保温作为基本方法，形成对不同厚度、顶面和吊模部位的不同处理办法。本发明确保不同发展阶段、不同暴露情况的混凝土均可一次性养护到位，杜绝混凝土开裂。
