Large-volume concrete construction method for linear accelerator
The invention discloses a mass concrete construction method for a linear accelerator, and relates to the technical field of building construction. Comprising the steps that firstly, pretreatment is conducted, the elevation is determined, reinforcing steel bars are installed, and formworks are erected; 2, concrete layered pouring and concrete slope layered pouring are carried out, vibrating is carried out through a vibrating rod in the pouring process, secondary vibrating is carried out before initial setting of the concrete, and finally surface treatment is carried out on the foundation slab concrete; and 3, curing the mass concrete, and after the mass concrete is poured, covering the mass concrete and carrying out rewarming curing on the mass concrete. According to the invention, the shrinkage of the concrete is reduced, the ultimate tensile strength of the concrete is improved, and the appearance and development of harmful cracks are effectively controlled.
本发明公开一种直线加速器大体积混凝土施工方法，涉及建筑施工技术领域；包括步骤：步骤一，预处理，确定标高，安装钢筋并搭设模板；步骤二，混凝土分层浇筑，混凝土斜面分层浇筑，浇筑过程中通过振捣棒进行振捣，在混凝土初凝前进行第二次振捣，最后对基础底板混凝土进行表面处理；步骤三，大体积混凝土养护，大体积混凝土浇筑完毕后，对其进行覆盖、复温养护。本发明减小了混凝土收缩，提高了混凝土的极限拉伸强度，有效的控制了有害裂缝的出现和发展。
