裂缝是水工混凝土建筑物最普遍、最常见的病害。不同种类的裂缝危害程度也不同,轻者会使混凝土内部的钢筋材料产生腐蚀,降低钢筋混凝土结构的承载力、耐久性和使用价值;严重的则会直接威胁到人民的生命、财产安全。因此,对混凝土裂缝的控制已成为水利工作者必须高度重视的问题之一。本文对常见的渗漏成因进行了分析,并针对这些常见的渗漏病害,提出一些具体的预防处理措施,介绍了此项工程采用的新材料和新技术。
Cracks are the most common and common diseases in hydraulic concrete structures. Different types of cracks also have different degrees of hazard. Light ones will corrode the steel materials inside the concrete, reduce the bearing capacity, durability and use value of the reinforced concrete structure; seriously, it will directly threaten people’s life and property safety. Therefore, the control of concrete cracks has become one of the problems that water conservancy workers must attach great importance to. This paper analyzes the causes of common seepage and puts forward some specific measures to prevent and deal with these common seepage diseases. The new materials and new technologies adopted in this project are introduced.
