Conductive plastic drain board

Abstract

The invention discloses a conductive plastic drain board which comprises a base plate, a metal wire and a filter membrane, wherein two sides of the base plate are provided with drain grooves; the base plate is made of conductive plastic; the metal wire penetrates through and is inserted into the base plate and is parallel to the drain grooves; and the base plate is wrapped by the filter membrane. The conductive plastic drain board can be used as an electrode for an electroosmosis method; and compared with a metal electrode traditionally adopted for the electroosmosis method, the conductive plastic drain board used as an electroosmosis electrode has the advantages that while the consolidation speed is ensured, the corrosion of the electrode during the electroosmosis process is avoided, the practicability of the electroosmosis method is enhanced, and possibility of popularizing the electroosmosis method is provided.

Description

[0001] Technical field [0002] The present invention is a geotechnical technology field, and especially involves a conductive plastic drainage board. Background technique [0003] Fine particles such as soft soil, sludge, sludge, tailings and other fine particles often have high water content, but the hydraulic penetration coefficient is small, so it is difficult to drain and solid.For the above -mentioned low hydraulic osmosis fine particles medium for drainage and solid, electrodiaquanic method is a very applicable method. The use of electrodium seepage method can efficiently eliminate the water in the soil, which can shorten the duration of the drainage and solid.And in the process of drainage and solid, the electrical seepage method produces negative porosity water pressure. It does not need to consider the heap rate and stability of the stacking rate like a stacking pre -pressure method. [0004] The traditional electrodelification method is to insert metal electrodes in th...

Problems solved by technology

However, metal electrodes are easily corroded during electroosmosis

After the metal electrode is corroded, the conductivity will decrease due to the "passivation" effect of the surface oxide, and if the metal electrode is disconnected due to "pitting corrosion" at some positions, it will cause a sharp increase in the resistance of the entire circuit

Electroosmosis has not been widely used in drainage consolidation applications due to corrosion problems of metal electrodes
