Problems solved by technology

However, there are still some difficulties in electroosmotic drainage consolidation of deep silt with existing electroosmotic electrodes, and its consolidation effect decreases along the depth direction. If the depth of the dredged silt exceeds 5m, the consolidation effect is not ideal

Abstract

The invention discloses an electron-osmosis electrode capable of distributing electric energy to deep in a soil body. The electron-osmosis electrode comprises a conductive water drainage board. The electron-osmosis electrode is characterized in that the conductive water drainage board comprises a conductive substrate, two surfaces of which are provided with longitudinal water drainage slots, wherein a longitudinal conductive wire is arranged in the conductive substrate; and the conductive wire is longitudinally connected with a power supply guide line in a spacing mode. The electron-osmosis electrode is simple in structure and convenient to use; the whole electron-osmosis electrode is upwards and downwards circulated with uniform current, so that electric fields are distributed uniformly, and therefore, loss, in a depth direction, of electric potential is avoided, and the water drainage effect in the deep of the soil body is improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an electroosmotic electrode for distributing electric energy deep into soil. Background technique [0002] With the increasing attention to environmental issues and the increasing demand for land resources, rapid and effective drainage and consolidation of dredged silt has become an urgent problem to be solved. Traditional drainage consolidation methods are difficult for dredging silt, a fine-grained material with high water content and low hydraulic permeability. Traditional methods mainly include heap preloading, vacuum preloading, dynamic compaction and various combinations of these three methods. The main difficulty of the surcharge preloading method is that the speed is too slow, and a large amount of earth and stone is required as surcharge. The surcharge preloading method usually takes several years to achieve a degree of consolidation of more than 80%. ...
