混凝土预制板渠道在疏通水源、农业灌溉发挥重要作用,不过当温度较低时极易因发生冻害出现渗漏,影响水资源的利用效率。冻害是威胁混凝土预制板渠道质量的重要因素,尤其在我国较为寒冷的北部地区,渠道冻害现象发生较为严重,给渠道经济效益的发挥造成严重影响,因此,加强对混凝土预制板渠道冻害方面的研究具有重要的现实意义。鉴于本文对混凝土预制板渠道冻害原因进行分析,并在此基础上找出针对性措施,以期为延长渠道使用寿命提供参考。
Concrete prefabricated channels in dredging water, agricultural irrigation play an important role, but when the temperature is low, it is easy to see the occurrence of frost damage, affecting water use efficiency. Frost damage is an important factor threatening the quality of precast concrete channel. Especially in the colder northern part of China, the phenomenon of frost damage in the channel is more serious, which has a serious impact on the economic benefits of the channel. Therefore, strengthening the research on the frost damage of the precast concrete channel It has important practical significance. In view of this article on the concrete prefabricated plate channel frost damage causes analysis, and on this basis to find out the specific measures in order to extend the service life of the channel to provide a reference.
