Description
Technical field
The present invention relates to a kind of compound underground anti-seepage isolation wall construction and construction method.
Background technology
In recent years, Urbanization in China is very fast, industry and municipal and environment-friendly infrastructure construction and operation management water
It is flat to relatively lag behind, cause China's Urban Underground water and soil pollution getting worse.The definition of soil pollution is：Because mankind's activity produces
Harmful, noxious material enter soil, accumulate to a certain extent, be from net energy in itself more than soil, cause soil property and matter
Amount change, forms influence and the harm to human body and ecological environment.Necessarily lead to due to the effect such as drenching with rain and washing away containing harmful
The percolate of composition, if do not taken effective seepage control measure, percolate can migrate with the seepage flow of underground water, pollute place
The pollution of surrounding ecology.Landfill Leachate Pollutants mainly include 3 types:(1) water soluble organic substance, it is represented by COD
Or total organic carbon (TOC), including volatile fatty acid and fulvic acid class and humic acids compound etc. (COD)；(2) it is special-shaped
The organic matter (XOCs) of biomass, is mainly derived from family and industrial chemicals, including a series of aromatic hydrocarbon
Thing, benezene material and chlorinated aliphatic hydrocarbon etc.；(3) heavy metal pollution, including Cd2+、Cr3+、Cu2+、Pb2+、 Ni2+And Zn2+Deng.City
City underground water and soil pollution has following features：(1) spatial spreading is big, and it is difficult to pollute Site evaluation；(2) soil body and
Underground water pollution coexists, and soil sample chemistry former state keeps difficulty big in sampling process；(3) based on combined pollution, often weigh
Metal and organic pollution coexist, it is desirable to it is wide to administer restorative procedure applicability；(4) Contaminants Transport depth is larger, geological conditions
Complexity, it is high to repair difficulty.Urban Underground water and soil pollution These characteristics for its reconnoitre, administer and repair bring huge science and
Technological challenge.
Divider wall early stage is mainly used in large-scale or reservoir seepage control project.With the development of technology, as shown in Fig. 1,
Divider wall is more and more used in pollution control engineering, and label 1 is divider wall in Fig. 1, and arrow represents that pollutant oozes
Saturating direction.Commonly using vertical divider wall engineering can following several class：Soil-bentonite divider wall, plastic concrete divider wall, commonly mix
Coagulate native divider wall (rigid concrete divider wall), Soil-cement piling wall and the compound divider wall of geomembrane-bentonite etc..No
The difference that stresses also with country to vertical divider wall type, China at present more uses cement (plastic concrete or soil cement)
Grouting curtain is as main divider wall form, to obstruct percolate in landfill yard.
Above-mentioned existing divider wall respectively has advantage and disadvantage.Form as shown in Figure 2 lists lacking for conventional vertical divider wall
Point.On the one hand, existing conventional divider wall is due to drying and watering cycle and the influence of Frozen-thawed cycled, the anti-seepage effect meeting after long service
Weaken, on the other hand, in face of increasingly complicated water and soil pollution situation, the vertical antiseepage divider wall of single structure has been difficult to meet
Complicated pollution situation.There are some researches show the presence of some heavy metals can hinder hydrated cementitious, and in a long time to cement
Firming body is exerted an adverse impact, and reduces the intensity of cut-pff wall, and through crack is produced in firming body, loses wall anti-
Isolation effect is oozed, so needing to consider the compatibility of cement and pollutant when using cement system cut-pff wall.Bentonite is although right
It is better than cement, but the cut-pff wall low intensity formed in the compatibility of pollutant, application is restricted, and answering in high concentration
The antiseepage barrier property for closing wall under the erosion of pollutant is typically difficult to the anti-seepage standard for reaching code requirement.
Although the compound divider wall permeability coefficient of geomembrane-bentonite is low, isolation effect is good, but Pollution Field in engineering
Often there is various heavy and situation that the pollutant such as organic coexists, pollution condition is extremely multiple often based on combined pollution in ground
Miscellaneous, form as shown in Figure 3, the earth working material of conventional single kind has certain limitation, and under complicated pollution condition,
Percolate and its a large amount of pollutants of carrying are easier to puncture barrier, greatly shorten service life, so this single structure
Divider wall is difficult to meet complicated every dirty antiseepage requirement.
The content of the invention
In order to solve the technical problem of the above, it is an object of the invention to propose a kind of compound underground anti-seepage divider wall knot
Structure and construction method.
In order to achieve the above object, the invention provides a kind of technical scheme：A kind of compound underground anti-seepage divider wall knot
Structure, it includes vertically arranged wall, every layer be arranged in wall uses different at least two one functional layers of material,

Plate or polyvinyl chloride panel.
Further, the material that functional layer uses includes mesoporous carbon/silica composite wood, attapulgite/activated carbon nanometer
Composite or the compound high hydroscopic resin of acrylamide.
Further, the distance between adjacent two layers functional layer is not less than 150mm.
Further, wall uses cement-bentonite or soil-bentonite.
Present invention also offers another technical solution：It is a kind of that wall construction is isolated based on above-mentioned compound underground anti-seepage
Construction method, comprise the following steps：
A. the position of antiseepage divider wall need to set to excavate grooving, injection wall body material in groove, is being inserted in materials for wall
Functional layer board-like material；
B. board-like material is inserted into designed elevation；
C. second piece of board-like material is inserted side by side, ensures the closely sealed matter of seam by snapping connection between two boards shape material
Amount, prevents percolate from leaching；
D. second piece of board-like material is inserted into designed elevation；
E. the follow-up board-like material of insertion is continued cycling through according to step c to step d to complete to constructing.
Further, in step a, excavation grooving is carried out by groover.
Further, in step a, materials for wall is cement bentonite hardening slurry or soil-bentonite compound.
Further, connecting portion of the board-like material including body, two sides in the height direction for being arranged on body, should
The horizontal cross-section of connecting portion takes the shape of the letter U, the mutual snapping of connecting portion of adjacent two boards shape material, the buckle in forming step b.
Further, connecting portion includes outer ledge, the holding tank between outer ledge and body, when adjacent two
The mutual snapping of connecting portion of block board-like material, the outer ledge of each connecting portion are inserted in the holding tank of another connecting portion.
Due to using above-mentioned technical proposal, the compound underground anti-seepage isolation wall construction of the present invention and construction method, comparing existing
There is technology, there is advantages below：
1st, can be according to the species of mixed pollutants, selectively using a variety of isolation sorbing materials, in underground anti-seepage
