基于保障安全的基本水尺断面混凝土冻融修复研究

以北京市密云水库张家坟水文站基本水尺断面混凝土冻融修复为例,介绍了工程修复准备,并对张家坟水文站基本水尺断面混凝土冻融修复进行了工程条件分析,并严格遵照修复设计依据制定了修复工程方案并实施。可以看出,对于长期运行的水工建筑物,进行常态化的工程修复非常必须,尤其是北方地区混凝土冻融破坏,更要从工程安全、迎汛安全、供水安全及水资源安全多角度评价,在工程实施中,还要注意生态环境安全保护。

Research on Freeze-thaw Repair of Basic Water Gauge Section Concrete Based on Ensuring Safety

Taking the concrete freeze-thaw repair of the basic water gauge section of the Zhangjiafen Hydrological Station of Miyun Reservoir in Beijing as an example,this paper introduces the engineering repair preparations,and analyzes the engineering conditions for the concrete freeze-thaw repair of the basic water gauge section of the Zhangjiafen Hydrological Station.In strict accordance with the restoration design basis,a restoration project plan was formulated and implemented.It can be seen that for long-running hydraulic structures,it is very necessary to carry out normalized engineering repairs,especially in the northern areas of concrete freeze-thaw damage,but also from the perspective of engineering safety,flood safety,water supply safety and water resources safety.In the implementation of the project,but also the main ecological environment safety protection.
