砼缺陷处理施工作业指导书
三峡永久船闸地下输水系统砼表面质量要求高，缺陷处理工艺要求高。为使缺陷处理工作做到程序化和规范化，以确保缺陷处理质量，特编写《永久船闸地下输水系统砼缺陷处理施工作业指导书》，用于指导缺陷处理施工作业。本作业规程是结合永久船闸地下输水系统砼缺陷的特点，依据《三峡一、二期工程主体建筑物砼表面缺陷处理技术要求（试行）》及缺陷处理相关设计文件编制而成。
1缺陷类型
  永久船闸地下输水隧洞砼质量缺陷分为五个类型：温度裂缝，层面缝渗水；结构缝渗水；砼点面渗及砼表面缺陷
Concrete Defects Construction work instructions
Three Gorges ship lock concrete underground water systems that require high surface quality, defect handling process demanding. In order to achieve defect handling procedures and standardized to ensure quality defect treatment, especially the preparation of "permanent lock underground distribution system Concrete Defects Construction work instructions" to guide the construction defect handling operations. This work order is a combination of permanent lock underground distribution system characteristics of concrete defects, according to "Three phase one and two of the main building concrete surface defect in the technical requirements (trial)" and Defects related design documents compiled.
One defect type
  Permanent ship lock of Concrete Underground Tunnel defects into five types: temperature cracks, seam seepage level; structural joints in the water seepage; concrete surface infiltration point and the concrete surface defects
