Diaphragm treatment in Zheshantou Dam abutment of Nanjing City

Integrated geophysical technology and incorporate geophysical drilling were used to detect the abutment of Zheshantou Dam.And then leakage channels were difined on both site of the dam.So concrete diaphragm thin wall and curtain grouting methods were used to solve the leakage of dam abutment.After the test of high water level,the seepage from dam leakage,reduced significantly.And the danger of reservoir were solved. 更多还原
