浅谈南水北调中线古运河枢纽工程的事先控制

The preceding-control of ancient canal hinge in the middle route of South-to-North Water Transfers mid-line project

古运河暗渠工程技术含量高,结构型式复杂,混凝土标号高,尤其浅埋暗挖段施工难度大,施工时安全隐患多,监理单位在施工前作好事先控制,及时复测测量控制网,把好原材料关,随时消除安全隐患、以动态管理、立体施工、交叉作业的思路督促施工,保证了安全质量无事故,按期完成施工任务。

Inward-ditch of ancient canal hinge project needs high technology because its structure pattern is complex, and the concrete intensity need to be high. Especially shallow-buried ＆ inward-excavation section construction is difficult to construct. There is many hidden danger in construction process. Surveillance institute controls the construction beforehand, resurvey measurement in timely, inspect raw material strictly, and eliminates hidden danger promptly. It supervises construction by the dynamic management, three-dimensional construction, and overlapping work mentality. This guaranteed the security, quality and finishes of the construction.
