| titleOfInvention | Electrical measurement method and device for detecting high polymer cutoff wall |
| abstract | The invention provides an electrical measurement device and a method for detecting a high polymer cutoff wall, and is used for detecting grouting states such as a buried depth and the like of an ultrathin high polymer cutoff wall in a dam seepage-proof reinforcement project. Alternate direct current is emitted toward the underground through a pair of current electrodes A and B which are buried in the earth surface; and then a potential difference between a pair of potential electrodes M and N which are placed in a drill hole, which is formed by power supply of the current electrodes, is measured; the potential difference is determined by positional relations of the electrodes, supply current, the dam, and resistivity of natural stratum; and the buried depth of the high polymer cutoff wall is measured through space distribution of the potential difference. The measurement device is low in cost, fast, convenient, simple and reliable in measuring method, and solves problems in the existing dam seepage-proof reinforcement projects. |
