Horizontal drainage plate-vacuum preloading combined electroosmosis system and sludge treatment method thereof

Abstract

The invention discloses a horizontal drainage plate-vacuum preloading combined electroosmosis system. The horizontal drainage plate-vacuum preloading combined electroosmosis system comprises a horizontal drainage plate system, an electroosmosis system and a vacuum preloading system, wherein the electroosmosis system comprises a plurality of vertical insulating assemblies, a plurality of anode steel bars, wires and a power supply; the wires comprise a positive wire and a negative wire; the plurality of vertical insulating assemblies are vertically distributed at the transverse edges of the twosides of a vacuum preloading groove; anode steel bar layers are distributed between the vertical insulating assemblies; horizontal drainage systems are arranged between the anode steel bar layers; thehorizontal drainage systems are in conduction connection with a vertical main pipe through branch pipes; cathode steel bar layers are fixed on the horizontal drainage systems; the anode steel bar layers are connected with the positive wire through branch wires; the cathode steel bar layers are connected with the negative wire through branch wires; and the wires penetrate through a sealing film and are connected with the power supply. The system can realize hydraulic filling and consolidation drainage at the same time, is simple and convenient to construct, saves energy consumption, avoids severe bending of plates, guarantees effective vacuum transfer, guarantees the treatment effect and increases the turnover utilization rate of a storage yard.

Description

technical field [0001] The invention relates to a horizontal drainage board-vacuum preloading combined electroosmosis system and a sludge treatment method thereof. Background technique [0002] Deep silt layers are often encountered in the construction of railways, houses, and airports in coastal areas of our country. Sludge has the characteristics of high water content, low permeability, and almost no bearing capacity, so the sludge needs to be treated to meet the needs of the project. Vacuum preloading technology is one of the widely used treatment methods in sludge treatment. Vacuum preloading technology has no pollution to the soil, low cost, and simple construction; compared with surcharge preloading method, it has shorter construction period and deeper reinforcement depth. Large size, saving pre-pressed materials and other advantages. The vacuum preloading method uses atmospheric pressure as the preloaded load, uses the sand layer on the soil as a horizontal drainage...

AI Technical Summary

Problems solved by technology

It solves the problem of poor bottom reinforcement, easy bending of the drainage board, blockage of the vacuum transmission, and inability to discharge polar water molecules. It can be consolidated and drained while blowing and filling, and the construction is simple and energy-saving. Reduce energy consumption, avoid severe bending of the plate, ensure effective vacuum transmission, ensure processing effect, save construction period, and improve the turnover utilization rate of the storage yard
