水利工程混凝土工程外观质量通病及防治措施

Current Engineering Appearance Common Quality Defects and Prevention Measurement of Hydraulic Concrete

水工建筑物外观质量是水工混凝土工程质量控制的重要环节之一。对当前水利混凝土工程蜂窝、麻面、空洞、错台、缺棱掉角、表面平整度不佳、伸缩缝处渗水、表面龟裂、深浅裂缝等外观质量通病的主要表现形式、成因及防治措施进行分析、探讨，旨在为实际施工中水工混凝土外观质量控制提供借鉴。

The appearance quality of hydraulic structure is one of the most important links for hydraulic concrete engineering quality control. Di- rected towards the common appearance quality defects of current hydraulic concrete project such as honeycomb, pockmarked face, voids, disloca- tion,lack of edge or angle, poor surface roughness, expansion joints seepage, surface cracking, various depth of crack, etc. , the main manifesta- tions,causes and prevention measurement are introduced, analysed and discussed, offer the reference for hydraulic concrete appearance quality control during the actual construction.
