Description
Technical field
The invention belongs to the refuse landfill antiseepages in Environmental Geotechnical field more particularly to a kind of selfreparing in geotechnical engineering
Layer.
Background technique
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 is 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 to install pollutant emission automatic monitoring equipment, the frequency that household refuse landfill sites pollutant emission is monitored
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, vertically also sets up the cut-pff wall of similar soil cement in refuse landfill.New landfill
The field weakly acidic pH value of Leachate site is less than 6.5, and the pH value of existing MSW landfill Leachate site is greater 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 Leachate site to leak, it is difficult to automatic leakage-blocking at present, in addition causes impervious liner and cut-pff wall 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 which a kind of impervious barrier can both be blocked caused by minute crack
New Landfill leakage, and can block because earthquake large deformation causes impervious barrier changing of the relative positions large fracture to prevent Leachate site dirty
Dye.
Summary of the invention
The present invention in order to overcome conventional garbage landfill yard impervious liner and cut-pff wall because have microcrack leakage due to not can from
Row repairs the problem of blocking new refuse landfill acidity Leachate site, and earthquake large deformation is overcome to cause impervious liner and cut-pff wall
The problem of changing of the relative positions large fracture is to cause acid Leachate site to pollute, the present invention provides a kind of refuse landfill antiseepages of selfreparing
Layer.
Technical solution of the present invention: a kind of refuse landfill seepage control layer of selfreparing, including several review one's lessons by oneself compound lever, antiseepage
Base；The compound lever of reviewing one's lessons by oneself is distributed in antiseepage base；The compound lever of reviewing one's lessons by oneself includes several intelligent activation switch, concentric first
Hollow stem and the second hollow stem, second hollow stem are located inside the first hollow stem, the first hollow stem and the second hollow stem
Full of solution is repaired in the space at both ends sealing, the first hollow stem and the second hollow stem interval, it is full of and swashs inside the second hollow stem
Hair repairs the liquid of solution solidification, and the intelligent activation switch is located in the opening of the first hollow stem side wall and can will be open
It is totally-enclosed；
The intelligent activation switch includes driving piece and frame, and the frame is hollow annular structure and frame hollow area
Domain is rectangle and the opening of frame outer ledge and the first hollow stem side wall fits closely, and the driving piece is rectangle and driving
Piece covers the closing of the hollow region of frame, and one end of the driving piece is fixedly connected with frame and drives the other edges of piece to be
Free movement end；The structure of the driving piece is the first hydrogel sheet, connection sheet and the second hydrogel sheet of successively fixed overlapping,
The material of first hydrogel sheet is the hydrogel for meeting alkali and shrinking and meeting acid plumping, and the connection sheet soft can deform, described
First hydrogel sheet is located at the outside of the first hollow stem, and the reparation solution on the inside of second hydrogel sheet and the first hollow stem connects
Touching.
Preferably, the material of second hydrogel sheet is the hydrogel met alkali swelling and meet acid contraction；Therefore when driving
When piece is located in pure water, or when driving piece is located in the liquid that pH value is neutrality, the first hydrogel sheet and the second hydrogel sheet
Equal length；And when the first hydrogel sheet only contact with pure water or the first hydrogel sheet only with pH value be neutrality liquid connect
When touching, and when the second hydrogel sheet is located at alkaline solution, the first hydrogel sheet length is constant and the second hydrogel sheet has elongation to become
At this moment gesture drives piece to be biased to the second hydrogel sheet direction warpage, i.e. driving piece covers the hollow region of frame, i.e. intelligent switch
Closing；And when the first hydrogel sheet is located at acid solution and swell increment and is greater than the second hydrogel sheet, at this moment drive piece to be biased to the
One hydrogel sheet direction warpage, i.e. driving piece open the hollow region of frame, i.e., intelligent activation switch is opened and allows the first sky
Reparation solution in heart pipe is flowed out from intelligent activation switch.
Preferably, the material of the connection sheet is magnetic rubber, fills magnetic iron powder in magnetic rubber, that is, rubber；The frame
Material by that can be magnetized is made, such as the material of frame is magnetizable ceramics, therefore frame and connection sheet have mangneto attraction
Power.Frame made of magnetizable ceramic can prevent acid and alkaline corrosion, while the mangneto attraction of frame and connection sheet can
With the more preferable hollow region for guaranteeing driving piece closing and covering frame.
Preferably, the compound lever parallelly distribute on 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 nanoscale silica dioxide granule
