近年来,我国水利事业取得了重大成就,但是随之也暴露出一系列问题,其中最为突出的是有关水库大坝混凝土防渗墙渗漏的问题。混凝土防渗墙起着支撑保护水库大坝、降低大坝应用风险的重要作用,因此在建设水库大坝的混凝土防渗墙时,要求其符合大坝的基本需求,达到防渗的实践性。水库大坝的建设的难度较大,属于大体积混凝土结构的建设,大体积混凝土结构的工程竣工后出现裂缝的情况屡见不鲜,随着水流渗入大坝内部,其结构的整体强度和承载能力都会受到影响,不仅会缩短维护周期,甚至会造成意外事故带来不必要的经济损失。因此,本文就水库大坝混凝土防渗墙的施工技术进行了详细的分析。
In recent years, great achievements have been made in water conservancy in our country, but a series of problems have also been exposed. The most prominent issue is the leakage of the seepage prevention concrete walls of reservoirs. The concrete cutoff wall plays an important role in supporting dam protection and reducing the risk of dam application. Therefore, it is required to meet the basic requirements of the dam when building the concrete cutoff wall of the dam to achieve the practicality of seepage prevention. The construction of reservoir dam is more difficult, which belongs to the construction of mass concrete structure. It is not uncommon for the cracks of concrete mass concrete structures to be completed. As the water flow penetrates into the dam, the overall strength and carrying capacity of the dam will be affected Impact, not only will shorten the maintenance cycle, and even cause unnecessary economic losses caused by accidents. Therefore, this article has carried on the detailed analysis to the concrete dam construction technology of the reservoir dam.
