摘要
为确保水库大坝安全运行、保障人民生命财产安全,需要定期对水库大坝进行现场检查和安全鉴定,并对工程存在的主要问题进行除险加固处理.田坝水库安全复核时,发现右岸库首渗漏严重,需要帷幕灌浆处理.结合帷幕灌浆施工资料对田坝水库灌浆施工过程中遇到的问题从多个方面进行详细对比分析,绘制帷幕施工综合分析图,最终明确了岩溶渗漏通道的发育程度、规模及高程,为后续施工指明了方向.
Abstract
In order to ensure the safe operation of the reservoir dam and protect the safety of people's lives and property,it is necessary to carry out regular on-site inspection and safety appraisal of the reservoir dam,and to carry out reinforcement treatment for the main problems existing in the project.During the safety review of Tianba reservoir,it was found that the first leakage of the right bank reservoir was serious,and the curtain grouting treatment was required.Based on the construction data of curtain grouting,a detailed comparative analysis was conducted on the problems encountered during the grouting construction process of Tianba Reservoir from multiple aspects.A comprehensive analysis diagram of curtain construction was drawn,and the development degree,scale,and elevation of karst leakage channels were ultimately clarified,providing guidance for subsequent construction.
