随着高性能混凝土的广普采用,基础设施中的钢筋混凝土在50～100年内免维修将成为可能。但在过去已建成投用的大量基础设施的维修工作也是迫在眉捷,而现有的维修工艺只能是“坏了修,修了坏”。钢筋混凝土工程不合格,必然引起使用上的不安全,而钢筋混凝土工程要整改和修复,也会给设计单位、施工单位带来很大的麻烦。本文就针对钢筋混凝土施工质量常见的通病进行分析,提出了一些具体控制措施。
With the widespread use of high-performance concrete, reinforced concrete in infrastructure will be free from maintenance in 50 to 100 years. However, maintenance work on a large number of infrastructures that have been completed and put into operation in the past is also pressing forward. However, the current maintenance process can only be “broken and bad.” The unqualified reinforced concrete project inevitably leads to the unsafe use, while the reinforced concrete project must be rectified and repaired, which will also bring great troubles to the design unit and the construction unit. This article analyzes the common problems common to the construction quality of reinforced concrete and puts forward some concrete control measures.
