采空区治理工程具有其特有的隐蔽性和复杂性,在注浆工程结束后很难准确的把握注浆工程效果,采用钻孔电视探测技术对某电厂的地基注浆处理效果进行了探测分析,结果表明,通过彩色钻孔电视观测,可以准确的了解注浆前采空区覆岩的空洞分布、裂隙发育情况以及注浆后浆体充填空洞、裂隙的详细情况。
Gob area management project has its unique hidden and complex, it is difficult to grasp the effect of grouting project accurately after the grouting project is completed, and the drilling grouting technique is used to detect and analyze the grouting effect of foundation in a power plant The results show that the color borehole TV observations can accurately understand the cavity distribution, the development of fractures and the details of grouting cavities and fractures before grouting.
