三峡永久船闸工程混凝土表面缺陷处理技术

三峡永久船闸混凝土缺陷处理是严格按照标准要求进行的，处理前的混凝土缺陷素描是其中的一个重要组成部分，对查清缺陷的数量、分布、性质起到了重要作用。在此基础上制定的处理原则及分区，使混凝土缺陷处理工作做到了有的放矢、重点突出。在处理过程中采用了大量的新工艺、新材料，施工质量良好。

Treatment technology of concrete surface defects in the Three Gorges Permanent Ship Lock Project

The concrete defect treatment in the Permanent Ship Lock of the Three Gorges Project is strictly performed according to the technical standards. The mapping of concrete defects before treatment is very important, which can find out the amount, distribution and features of the defects. Then the treatment principles and zoning would be determined in order to perfect the concrete defect treatment. During the construction process, a lot of new technologies and new materials have been adopted so that the construction quality is high.
