It is equipped with anode electrode and cathode electrode, the anode electrode connects DC power supply with cathode electrode, under the action of direct current
So that the moisture in roadbed filling is collected in cathode electrode nearby and be discharged, to reduce roadbed moisture content；Specific operation principle
It is as follows：
Under normal conditions, soil particle meeting adsorpting anion keeps its surface negatively charged.Particle surrounding forms an electricity
, polar water molecules, aquation cation are attracted to grogs surface by electrostatic attraction, simultaneously because by Brownian movement warm-up movement
Diffusion, practical cation is unevenly distributed.Place near grogs surface, polar water molecules, aquation sun
Ion arranges closely, forms adsorption layer；The place slightly remote from grogs surface distance, electrostatic attraction reduce, polar water molecules,
Aquation cation arranges not to be so close, formation diffusion layer.The ion adsorbed in adsorption layer and diffusion layer, sign
With the negative electrical charge on grogs surface on the contrary, also known as counter-ion layet.The negative electrical charge that electric double layer refers to grogs surface constitutes electric field internal layer,
Counter-ion layet constitutes electric field outer layer.If applying certain potential difference at soil body both ends, electric double layer will rupture, and positive charge moves
To cathode, and negative electrical charge shifts to anode, and since the first layer of electric double layer is firmly connected to the soil body, the movement of this layer is very tired
Difficulty, therefore layer 2-only drives liquid to move together, material is thus formed electric osmoses；The weak knot in soil can be discharged by electric osmose
Heshui and Free water.
It is further preferred that in above-mentioned processing method, the cathode electrode is nearby provided with drainage channel；In cathode,

It is further preferred that in above-mentioned processing method, the anode electrode and cathode electrode are made of inert material；
Electro-osmosis method processing is carried out using inert electrode (including non-metal electrode such as graphite electrode, inert metal electrode such as silver electrode etc.)
When, the electrode bar that will turn on direct current is inserted into soil, and the water in soil occurs electrochemical change under the action of direct current, makes sun
Electric field can be formed between pole and cathode, it is generally the case that soil particle can adsorpting anion keep its surface negatively charged, in soil
Polar water molecules easily combine with cation and form aquation cation.After being inserted into electrode under the action of electric field force, aquation sun from
Son can under the action of electric field force towards cathode displacement, meanwhile, hydrone by the effect of frictional force drive again around freely
Water and part weak bound water form electroosmosis to movable cathode (macro manifestations are the viscosity of water).In cathode, moisture subnumber
When amount is assembled to a certain extent, water is released from ion hydration, and making cathode, nearby moisture increases, the row being arranged from cathode
Aquaporin is discharged.After Free water and part weak bound water are discharged, the structure and property of grogs can all change.Free water and
Part weak bound water is discharged, and hole reduces, and the occlusion between soil particle is close.Therefore, soil bearing capacity is improved, the soil body
Angle of friction and cohesive strength all increase so that soil shear strength increase.It can be incited somebody to action after subgrade soils moisture content is down to specified value

Fe2+Fe (OH) is generated in aqueous solution2·nH2O, positively charged Fe (OH)2·nH2O is to movable cathode, as Fe (OH)2·nH2O
Cathode is moved to, hydrone is sloughed from the soil body and largely assembled, and drainage channel is arranged at cathode at this time, and water will be arranged from cathode
Go out.The discharge of moisture reduces soil moisture content, improves soil bearing capacity.Fe (OH) in the soil body simultaneously2It is oxidized to Fe (OH)3
And cementation is generated with grogs, it can further increase resistance of soil, and the electronics that oxidation generates, pass through via anode straight
Galvanic electricity to cathode, and at negative electrode metal ion or water electrolysis generate hydrogen ion occur reduction reaction generation it is corresponding
Metal or hydrogen.After subgrade soils moisture content is down to specified value, sealing material, sealing material are directly filled in electrode tube
Anchoring system can be formed with metal electrode after condensation hardening, roadbed side slope is anchored.
It is further preferred that in above-mentioned processing method, hollow tubular structure is used in the cathode electrode, in the pipe
Shape structure is equipped with permeable hole；As shown in Fig. 1 (a) and Fig. 1 (b)；Permeable hole is opened at a certain distance in cathode pipe surface, it is permeable
Hole is symmetrical on material cross section, and bore axis is vertical each other；Preferably, adjacent two rows of permeable hole longitudinal pitches are
10cm, the aperture Φ of permeable hole3For 6~8mm, ensure that smoothly discharge is interior and is discharged for the moisture being pooled at cathode tube.Electrode is long
Degree and subgrade soils equivalent width.
It is further preferred that in above-mentioned processing method, the anode electrode uses solid tubular structure；
The specific design method of the above method is as follows：
(1) voltage determines
Voltage usual range is U=24V~160V when electric osmose.But in view of work progress does not influence the normal fortune of road
Battalion, while considering speed of application, to approach or be advisable no more than 72V safe voltages, and when overtension, the soil body will be made to generate
Amount of heat, energy consumption increase, and uneconomical.
(2) selection of electrode material and size determine
Electrode material generally can be divided into two classes, and one kind is to utilize electrode tube or electrode made of inert material (such as graphite)
Stick since electrochemical change will not occur under additional power source effect for inert electrode, thus carries out electro-osmosis method using such electrode
When construction, it can take out and recycle after energization；Another kind of electrode material is reinforcing bar or steel pipe, using irony electrode
It can cause to participate in electrochemical reaction generation Fe (OH) in electric osmose experimentation2With Fe (OH)3Colloid, colloid can be generated with grogs
Cementation can further increase soil strength.The reinforcing bar or graphite rod of a diameter of 16~24mm, cathode material may be selected in anode stub
Outer diameter Φ may be selected in material1For the steel pipe or graphite-pipe of 21~27mm, corresponding internal diameter Φ2For 18~24mm, while in cathode pipe surface
Permeable hole is opened at a certain distance, and permeable hole is symmetrical on material cross section, and bore axis is vertical each other, adjacent two rows
Permeable hole longitudinal pitch is 10cm, the aperture Φ of permeable hole3For 6~8mm, ensure that the moisture being pooled at cathode tube is smoothly discharged
It is interior and be discharged.Cathode tube is as shown in Figure 1.Electrode length and subgrade soils equivalent width.
(3) pole layout
Electrode arrangement mode is as shown in Fig. 2, due to the available power limited of DC power supply, to the longer construction section of length
Required electric osmose power is larger, thus is powered using multiple DC power supplies in entire construction section domestic demand；The quantity of DC power supply
It need to be determined in conjunction with required laying number of electrodes, construction segment length in roadbed moisture content, unit length section.
To common engineering, an operation area is defined as every 40~60m along route direction.In each operation area, electrode hole
The determination of position should be determined according to voltage strength between adjacent electrode and soil moisture content height.Cathode and anode is respectively arranged
In different height, and anode tube and cathode tube are along the interspersed arrangement of short transverse.Each layer of anode tube and its adjacent lower layer are cloudy
Pole pipe is an electric osmose layer position, and the same electric osmose layer of each operation area is powered by a DC power supply.
Preferably, adjacent two be may be selected in conjunction with voltage strength, soil moisture content and the roadbed height between adjacent electrode
Vertical interval between a electrode is 0.6~1m, between the cathode tube and cathode tube at sustained height, anode stub and anode stub it
Between distance be about 1~1.2m.It is different according to roadbed height, it, need to will be cloudy to ensure that the moisture being pooled at cathode can be discharged as early as possible
The descending that the gradient is 2%~4% is arranged in pole pipe.
(4) soil body resistance is estimated
The estimation of soil body resistance should be analyzed as unit of operation area；In each operation area, the soil body between anodic-cathodic
All-in resistance show as apparent resistance RApparentIf considering the interface resistance between electrode and surrounding soil, electricity between every a pair of electrodes
Hinder RApparent, by electrode resistance electrode RElectrode, electrode and soil body interface resistance RInterfaceAnd soil body resistance RSoilThree parts are constituted：
RApparent=RElectrode+RInterface+RSoil (1)
In formula：RElectrode- electrode material itself resistance (Ω), to metal electrode RElectrode≈0；
RInterface- the interface resistance (Ω) between electrode and the soil body；
RSoil- soil body resistance (Ω).R=ρ l/A, ρ are soil body resistivity, and l is anodic-cathodic distance, and A is soil body area.
Wherein, soil body electricalresistivityρ is tested with Miller resistance (20cm × 20cm × 18cm) case.
Interface resistance RInterfaceComputational methods are：
In formula：kj- interfacial resistivity (Ω cm2)；
rat—s1/s2, conductive area ratio, dimensionless；
s1, s2Conductive area (the cm of-electrode and soil2).
Since subgrade drainage is these electrodes and soil body can be divided into band between them by much being constituted to electrode,
And it is parallel relationship that can be considered as with power supply, electric osmose area circuit is just reduced to Fig. 3 institutes representation model：
Electric osmose place all-in resistance Σ RApparentShown in computational methods such as formula (3)：
Wherein：N-electrode logarithm.
(5) output power estimation and DC power supply are chosen
Estimation electric current aids in determining whether power supply unit power.Typically, since during electric osmose soil moisture content change
Change can cause resistance to change, and then electric current is made to change from high to low during electric osmose, and initial current is estimated by formula (4)
It calculates：
And power is estimated by initial current and electric power output voltage, as shown in formula (5)：
P=UI
(5)
During DC power supply is chosen, except supply voltage to be ensured meets construction requirement and ensures the opposite of output voltage
Outside stablizing, it is also contemplated that the construction cost of entire project.According to the difference of engineering properties, there is also differences for selected power supply mode
It is different.In general, when construction site provides alternating current, AC transformer may be selected and rectifier is converted to AC power directly
Galvanic electricity source is powered.It is easy to operate to carry out the advantages of alternating current turns direct current using rectifier, and voltage is relatively stablized and is not necessarily to
Individually power generation, but AC transformer must be isolating transformer type, can cause when being otherwise powered with big ground short circuit, and equipment at
This is higher.The needs of higher-wattage in work progress can be met by being powered to engineering using dc generator, but use direct current
Generator, which carries out power supply for a long time, so that fuel consumption is increased, while being powered using generator and will appear output voltage shakiness
Calmly, phenomena such as voltage increases with electric current and is reduced；The selection of specific power supply unit should be according to equipment price, operating expenses and work
Journey demand etc. is because usually determining.
(6) it is powered and observes
Electrode installation terminate after, electric osmose region electrode is connect with DC power output end in time, electric osmose region electrode with it is defeated
The connecting terminal for entering conducting wire is bound securely with iron wire.Circuit connection is checked before being powered, it need to be by personnel when the overtension of selection
It withdraws, can close a switch after confirmation is errorless.Electro-osmosis method drain step be first to top layer's electric osmose layer position of entire roadbed into
Row, which is powered, to be drained, and should be paid close attention to roadbed moisture content situation, voltage, curent change situation constantly in drainage procedure, be waited for that the layer soil body contains
Water rate terminates to be powered when being down to no more than optimum moisture content 1%-3%；It is powered again to its next layer of electric osmose layer position, when aqueous
Rate continue when dropping to identical numerical value to lower layer's roadbed carry out draining until entire roadbed moisture content be all down to required moisture content, stop
It is powered, carries out moisture content selective examination and adjusts moisture content.When roadbed overall moisture content all reaches no more than optimum moisture content 1%-3%
