摘要
结合某燃气电站基础大体积混凝土的施工,介绍了钢筋绑扎、模板安装、预埋件埋设、混凝土浇筑阶段的主要技术措施。通过合理选材、降低浇筑温度、加强养护和温度监测等手段,对混凝土内外温差进行控制,避免了有害裂缝的产生。工程实践表明:采取上述施工方法能够确保工程质量,是安全有效的。
Combined with the mass concrete construction of a gas turbine plant foundation, the main construction measures such as assembling reinforcements,installing templates, inbuilding embedded parts and concreting were introduced.The temperature differences between internal and external concrete were controlled and the damaged cracks were avoided by choosing reasonable materials, decreasing the casting temperature, curing concrete and monitoring temperature, et al.Engineering practices show that those construction measures above can assure the engineering quality, which are safe and effective.
