摘要
三峡冲沙闸下游消能防冲建筑物工程具有混凝土标号高、混凝土浇筑块体尺寸大、温控标准高及混凝土料运输距离远等特点,混凝土温度控制方面采取了优化混凝土配合比、降低混凝土出机口温度、控制混凝土浇筑温度回升及初期通冷却水等综合措施,监测资料表明混凝土内部最高温度均控制在设计允许最高温度以下,取得了满意的效果,为其他类似工程混凝土温度控制提供了参考。
The TGP energy dissipator in downstream of sediment flushing sluice features high concrete grade, large size of concrete block, strict temperature control requirement and long concrete transport distance etc. To control concrete temperature, the comprehensive measures of concrete ratio optimization, lowering down concrete temperature at mixer outlet, controlling temperature re-rising of placed concrete and cooling water at initial period of concrete placing etc. were taken. The monitoring data demonstrates ...
