Abstract:
A plurality of rows of wells are drilled in the soil of the area to be stabilized, and then pairs of electrodes, i. e. , an aluminum anode and a copper-graphite cathode connected to a source of a bipolar pulse current, are inserted into each well in such a manner that during operation all anodes of odd wells are connected to a positive terminal (for odd pulses) of the source, while all cathodes of even wells are connected to a negative terminal (for odd pulses) of the source. After a certain period of treatment the anodes and cathodes are reversed so that all anode of even wells are connected to the positive terminals (for even pulses) of the source, whereas the cathodes of the odd wells are connected to the negative terminal of the source. Controlled directional structuring of the soil mass is carried out by adjusting the duration of current pulses, intervals between two sequential bipolar pulses of pulse current, and current density in the pulses. Prior to initiation of the soil stabilization process, salts, which correspond to the type of treated soil, are introduced into the wells.
