摘　　要：文章从工程概况、渡槽维修内容、止水更换方案及施工工艺,并结合工程运行观测检查结果,利用环氧砂浆修补破损混凝土、聚硫密封胶填充伸缩缝止水、拉杆粘贴碳纤维布提高抗拉强度、渡槽内壁喷涂II型聚脲涂料防水防碳化、槽身外壁及支持混凝土表面喷涂渗透性涂料防碳化等综合维修加固技术要求,详细介绍陆浑灌区口孜U形混凝土渡槽维修加固方案及施工工艺,现该渡槽已投入运行,达到了预期理想效果。结合工程运行实际情况,提出对U形混凝土渡槽维修建议,以期为相似水利工程维修加固提供技术参考,意在与同行共同研究学习该项技术,使之更成熟,更好地服务水利事业的发展。Based on general situation of the project, aqueduct maintenance content, water stop replacement plan and construction technology, combined with the results of project operation observation and inspection, this paper uses epoxy mortar to repair damaged concrete, polysulfide sealant to fill expansion joints, tie rods to paste carbon fiber cloth to improve tensile strength, and spray type II polyurea coating on the inner wall of the aqueduct for waterproofing and carbonization. According to the comprehensive maintenance and reinforcement technical requirements such as spraying permeable coating on the outer wall of the trough body and the surface of supporting concrete, this paper introduces the maintenance and reinforcement scheme and construction technology of Kouzi U-shaped concrete aqueduct in Luhun irrigation area. Now the aqueduct has been put into operation and achieved the expected ideal effect. Combining the actual situation of the project operation, some suggestions for the maintenance of the U-shaped concrete aqueduct are proposed, in order to provide technical reference for the maintenance and reinforcement of similar water conservancy projects. It is intended to study and learn this technology together with peers, so as to make it more mature and better serve the development of water conservancy.
