建设高标准的混凝土衬砌渠道是提高输水利用率的重要手段,而在渠道衬砌工程中,渠道混凝土衬砌的冻害是一个较突出的问题。结合济平干渠工程渠道混凝土衬砌设计及施工的经验教训对渠道混凝土衬砌的冻害机理及防治措施作一初浅探讨。
The construction of high standard concrete lining channel is an important means to improve water utilization efficiency. In the channel lining project, the freezing damage of channel concrete lining is a more prominent problem. Based on the experiences and lessons of concrete lining design and construction in canal channel of Jiping main canal, the preliminary study on the mechanism of freezing damage and prevention and cure measures of canal concrete lining is made.
