摘要
针对官地水电站碾压混凝土重力坝6 m升层快速施工的特殊要求,通过采取切实有效的温控防裂施工技术,即:降低混凝土出机温度、减少混凝土在运输和浇筑过程中的温度回升、控制坝体最高温度等,使大坝混凝土的质量得到了保证。
Aiming at the special requirements on the rapid construction with the placement-lift of 6m for the roller-compacted concrete gravity dam of Guandi Hydropower Station,the quality of the dam concrete is ensured through the adoption of the construction technology of temperature control and anti-cracking,. i. e. lowering the mixer outlet temperature of concrete,reducing the concrete temperature rise during transport and placement,controlling the maximum temperature of the dam body,etc.
