摘　　要：近些年,我国城市污水处理能力有所提升,我们国家对水处理和环境保护板块明确总体发展前景,对“再现城市碧水清波”使命的愿景更加重视,在城镇污水建设方面,根据《“十三五”全国城镇污水处理及再生利用设施建设规划》,兴建城乡一体化的大中型污水处理厂日益增多,在施工期间遇到很多重点和难点,其中污水构筑物结构施工过程中,结构的裂缝防止以及抗渗漏的处理较为关键,混凝土结构中的裂缝容易造成池体渗漏,影响构筑物的基本使用功能;怎样控制裂缝的发生风险是影响施工质量的当务之急。文章就污水处理构筑物池体的裂缝成因、裂缝防治及结构渗漏处理结合工程实践进行初步分析和探讨。In recent years,China's urban sewage treatment capacity has improved,and China has clearly developed the overall development prospects for water treatment and environmental protection sections.The vision of"reproducing city clear water clearing"mission is more attaches importance to the construction of urban sewage,according to"The 13th Five-Year Plan"for Town Sewage Treatment and Renewable Utilization Facilities Construction,the large and medium-sized sewage treatment plant integrating urban and rural integration is increasing,and many key points and difficulties are encountered during construction,including cracks in structural construction in the construction of sewage structures.Preventing and the treatment of anti-leakage,cracks in concrete structures are likely to cause leakage of pool,affecting the basic use of structures;how to control cracks is the top priority affecting construction quality.In this paper,the practice of cracks in sewage treatment structural pools,crack control and structural leakage treatment combined with engineering practice were preliminary analysis and discussion.
