白鹤滩水电站左岸进水塔大体积混凝土施工的质量管控

Quality Control of Mass Concrete Construction of Intake Tower on the Left Bank of Baihetan Hydropower Station

在白鹤滩水电站左岸进水塔塔体大体积混凝土施工过程中,首次采用了大型液压悬臂爬升模板,同时,通过对混凝土坍落度、和易性、振捣工艺以及温度控制等方面结合现场实际情况有针对性地制定了一系列措施及方法,对混凝土施工全过程进行质量管控,提升了左岸进水塔大体积混凝土施工的整体质量,实现了左岸进水塔塔体大体积混凝土快速、安全、优质施工,介绍了具体的管控过程。

During the mass concrete construction of the intake tower on the left bank of Baihetan Hydropower Station,the large hydraulic cantilever climbing formwork was used for the first time.At the same time,combining with the actual situation on site,a series of measures and methods were formulated to control the quality of the whole process of concrete construction through the aspects of concrete slump,workability,vibration technology and temperature control,which improves the overall quality of mass concrete construction of the intake tower on the left bank,realizes the rapid,safe and high-quality construction,and introduces the specific control process.
