引水隧洞施工缺陷分析及处理方法
|
摘要
引水隧道工程是一个隐蔽的工程,很难直接观察到在施工中留下的缺陷,所以在施工过程中对引水隧道应坚持及时检查、发现问题并且改进施工技术。在此理念下,首先对施工缺陷检测方法进行分析,在此基础上提出了探地雷达检测法,并对8种混凝土施工缺陷种类及原因进行分析,并采用增加结构强度、灌浆、防渗和排水、隧洞钢衬安装等技术措施修复施工缺陷,从而有效提高隧洞混凝土施工质量。
Diversion tunnel project is a concealed project,which is difficult to directly observe the defects left in the construction,therefore,it is important to inspect and improve the tunnel timely in the construction process. The detection methods of constructing defects are analyzed and the ground penetrating radar detection method is also put forward,based on the cause analysis of eight kinds of concrete constructing defects. Finally,some effective technical measures to repair constructing defects are discussed so as to improve the quality of tunnel concrete construction by the techniques of grouting,draining,steel lining,etc.
