摘 要:分析了复杂型钢组合结构内浇C70混凝土的特点和难点,按照优化的配合比进行生产和质量控制,对比分析多种施工工艺后采用导管导入法进行内浇混凝土施工,并在结构实体内预埋应变计等测试元件检测混凝土的硬化性能以评价结构浇筑质量。检测数据表明,所选择的混凝土配合比、施工浇筑工艺和质量控制过程能够满足结构质量控制要求。
Abstract: Characteristics and difficulties of complex steel composite structure cast in C70 concrete are analyzed, optimized mixing proportion for production and quality control are carried out. Cast concrete construction used by catheter introduction method is compared and analyzed after a variety of construction techniques, structure casting quality are evaluated by hardening properties of tested concrete which is embedded strain gauge in structural concrete. The monitoring data shows that, structure quality control requirements are satisfied by choosing mix proportion of concrete, construction cast technique, and quality control process.
