The Quality Inspection of Plastic Concrete Anti-Seepage Wall For Rushan River Groundwater Reservoir

The construction of anti-seepage wall is an important part of the Rushan River underground reservoir project. The quality inspection of the anti-seepage wall is an important measures to ensure the anti-seepage reliability, and has important practical significance. The quality of anti-seepage wall is inspected by ultra-high density electrical method, on the basis of investigating the stratum lithology of Rushan River and the construction method of anti-seepage wall. The following conclusions are as drawn. (1) Ultra-high density electrical method greatly improves the quantity of data acquisition by using the mode of multi-channel, multiple electrode, data automatic acquisition. (2) The arrangement of disposable survey line is adopted in the inspection, which can easy to operate and save inspection time. (3) With increasing of the inspection data, the error of inversion system is reduced, and the contour map of apparent resistivity is more reliable. (4) The contour map of apparent resistivity shows that the anti-seepage wall has good continuity, and obvious discontinuous anti-seepage wall is not found; the connection between the anti-seepage wall and the bedrock is well, indicating that the quality of anti-seepage wall meets the anticipated effect, the next construction can be implemented.
