水利水电施工中混凝土裂缝的主要原因及防治技术

On the main causes and prevention technology of concrete cracks in the construction of water conservancy and hydropower

水利水电工程是国民经济的重要基础设施,对国民经济的发展有很大影响,因此,对水利水电施工建设的要求就非常严格。在具体施工过程中,其中最明显的问题就是混凝土裂缝问题,混凝土裂缝会严重影响水利水电工程施工进度和质量,但是一般情况下混凝土出现裂缝属于质量通病,很难从根本上进行解决,要想避免混凝土出现裂缝就要通过科学的防治技术来进行控制,加大对裂缝的有效防控和养护,从而减少裂缝的产生。

Water conservancy and hydropower project is an important infrastructure of the national economy, which has a great impact on the development of the national economy. Therefore, the requirements for water conservancy and hydropower construction are very strict. During the construction, it turns out that the most obvious problem is the concrete crack, which would severely affect the progress and the quality of the construction of water conservancy and hydropower projects. However, the concrete cracks are common quality defects that are difficult to solve completely. Therefore,in order to avoid the concrete cracks it is necessary to control them through scientific prevention and control technology that can strengthen the effective prevention and maintenance of cracks to reduce their occurrence.
