摘　　要：渡槽作为一种输水建筑物,常建于山谷、洼地、河流、公路之上进行高空输水作业。在建设过程中,尽管各参建方严格管控施工质量,但总会因为一些客观因素导致施工作业存在一定问题,如槽身混凝土因各种原因产生裂缝而致渗漏等。针对渡槽槽身发生渗漏的问题,采用“聚脲注浆防渗,聚合物防水砂浆补强”的维修办法,较好地解决了渡槽裂缝的渗漏问题。As a kind of water transport structure,aqueduct is often built on valleys,depressions,rivers and highways for high-altitude water transport operation.In the construction process,although the participating parties strictly control the construction quality,there could always be some problems during construction because of certain objective factors,such as cracks and seepage in the concrete of the aqueduct due to various reasons.In view of such seepage problem,the maintenance method of"polyurea grouting for seepage prevention and polymer waterproof mortar for reinforcement"has been adopted,solving the problem of cracks and seepage in the aqueduct desirably.
