A method of detecting the integrity of the impervious wall polymer potential imaging method

The present invention relates to a method for detecting the integrity of the impervious wall polymer potential imaging method, comprising the steps of: setting the current transmission system on the side of the impervious wall, this current transmission system comprising a remote current electrode, a parallel seepage linear current source electrode and a wall connecting the current axis disposed between the linear emitting device the current source electrode and a distal electrode current; current transmission system; impervious wall to the other side of the surface potential measurement, potential measurement system provided in the surface potential measurement alternately transmitting side cutoff wall underground DC current, potential measurement system at spaced intervals measured potential distribution of the points on the other side cutoff wall; potential distribution drawing of each point from the measured data, comprising the equipotential FIG line or the equipotential lines in FIG gradient; in accordance with the potential distribution determines the potential size and shape distribution impervious wall integrity. Compared with the prior art, the present invention has high detection efficiency, low cost, and easy.
