Description
Technical field
The invention belongs to the Environmental Geotechnical fields in geotechnical engineering more particularly to a kind of rubbish of intelligent drives selfreparing to fill out
Bury an impervious barrier.
Background technology
With the expansion of city size, how to handle more and more house refuses becomes one very important
Business.Refuse landfill is built to be widely used at home.《Household refuse landfill sites control standard》GB 16889-2008 are defined
The special emission limit of refuse landfill water pollutant, such as COD, biochemical oxygen demand (BOD) and content of beary metal limit value etc., together
When point out to need that pollutant emission automatic monitoring equipment, the frequency for being monitored household refuse landfill sites pollutant emission are installed
It needs to carry out by specification with the sampling time, the monitoring that monitoring well carries out groundwater quality is additionally needed, to contamination well and pollution
The water quality monitoring frequency of monitoring well no less than once every two weeks, should carry out an impervious liner integrity check in every 6 months.To have
Effect solves the leakage problems of landfill leachate, and the cut-pff wall of similar soil cement is vertically also set up in refuse landfill.New landfill
Field Leachate site is less than 6.5 in faintly acid pH value, and the pH value of existing MSW landfill Leachate site is more than 7.5.Based on impervious liner and antiseepage
Wall can prevent underground water from being polluted by the Leachate site of refuse landfill.But impervious liner and cut-pff wall are split after building up if there is small
When seam causes the Leachate site to leak, it is difficult to automatic leakage-blocking at present, in addition impervious liner and cut-pff wall is caused to generate in case of earthquake
It will cause refuse landfill antiseepage is of serious failure for the changing of the relative positions, it is therefore desirable to caused by a kind of impervious barrier can both block minute crack
New Landfill leakage, and can block because earthquake large deformation causes impervious barrier changing of the relative positions large fracture so as to prevent Leachate site dirty
Dye.
Invention content
The present invention is in order to overcome the impervious liner of conventional garbage landfill yard and cut-pff wall can not be voluntarily when having crack-leakage
Reparation blocks the problem of new landfill yard acidity Leachate site and earthquake large deformation is overcome to cause impervious liner and the cut-pff wall changing of the relative positions big
The problem of crack is so as to cause acid Leachate site to pollute, the present invention provides a kind of refuse landfills of intelligent drives selfreparing to prevent
Infiltration layer.
Technical scheme of the present invention：A kind of refuse landfill seepage control layer of intelligent drives selfreparing, is reviewed one's lessons by oneself including several
Compound lever, antiseepage base；The compound lever of reviewing one's lessons by oneself is distributed in antiseepage base；It is described review one's lessons by oneself compound lever include several intelligent activation switch,
Concentric the first hollow stem and the second hollow stem, second hollow stem are located inside the first hollow stem, the first hollow stem and the
Full of reparation solution, the second hollow stem in the space at the both ends sealing of two hollow stems, the first hollow stem and the second hollow stem interval
Inside repairs the liquid of solution solidification full of excitation, and the intelligent activation switch is located on the first hollow stem side wall；
The intelligent activation switch includes the first water-setting blob, the second water-setting blob, the first spring, second spring, connecting rod, envelope
Occlusion, the first tablet and the second tablet, first tablet are located on the outside of the first hollow stem, and the second tablet is located at the first hollow stem
In the space at the second hollow stem interval, pass through the first parallel hydrogel between the first tablet and the first hollow stem side-wall outer side
Block and the connection of the second water-setting blob, pass through the first parallel spring and second between the second tablet and the first hollow stem inside sidewalls
Spring connects, and the first tablet, connecting rod, closing cock and the second tablet are fixedly connected sequentially, and it is hollow that closing cock can be embedded in first
Trepanning on bar side wall and it can prevent the liquid in the first hollow stem from being flowed out from tapping, the cross-sectional area of connecting rod is less than the
Perforated area on one hollow stem side wall and can in trepanning free shuttling.
Preferably, first water-setting blob and the second water-setting blob shrink hydrogel, such as meet what acid was shunk to meet acid
Polyurethane hydrogel.
Preferably, the material of second tablet is magnetizable ceramics, and the second tablet made of magnetizable ceramic can be with
Prevent acid and alkaline corrosion；The material of second hollow stem is magnetic rubber, i.e., fills magnetic iron powder in rubber；Such second
Tablet and the second hollow stem have mangneto attraction, make second so as to still have in the case of the first spring and second spring failure
The active force that tablet is moved to the second hollow stem.
Preferably, the compound lever parallel distribution of reviewing one's lessons by oneself is in antiseepage base.
Preferably, the reparation solution is silicon sol solution, and the silicon sol solution is nano level silica dioxide granule
It is distributed in alkaline solution, when solution switchs to acidity, these nano particles are first is gradually condensed into chain structure and then formation three-dimensional
The gel of reticular structure leaks so as to block.
Preferably, the excitation repairs the liquid of solution solidification as acetum and pH value is between 5 to 6.
Preferably, solution, pressure control pump and the first hollow bar side are repaired to injection in compound lever is reviewed one's lessons by oneself with pressure control pump
Wall connects, and the space repaired solution and enter the first hollow stem and the second hollow stem interval of pressure control pump injection, pressure control
System pump can be precisely controlled the pressure that solution is repaired in injection.
Preferably, the antiseepage base cures sand for Ludox and obtains, i.e., nano level silica dioxide granule is distributed in

Leakage；
（2）Cause the selfreparing anti-seepage method of leakage for changing of the relative positions crack：When earthquake causes impervious barrier changing of the relative positions crack, at this moment
One hollow stem and the second hollow stem are all stitched along the changing of the relative positions to be broken, the reparation solution in the first hollow stem and the second hollow stem clearance space
The liquid that solution solidification is repaired with the excitation in the second hollow stem mixes, and repairs the liquid that solution repairs solution solidification in excitation in this way
Gel is formed under body effect so as to block leakage.
