Description

A kind of seepage proof curtain structure of descending flexibly
Technical field
The utility model relates to a kind of leakage preventing structure field, especially a kind of seepage proof curtain structure of descending flexibly.
Background technology
The current Tailings Dam kind of China is complicated, quantity is various, widely distributed, and Tailings Dam environment event takes place frequently, and the mine tailing that quantity is surprising causes severe contamination to the area ecological environment of mine periphery and water resource, directly destroys ecological environment.By vertical seepage control structure is set for Tailings Dam, reduce mine tailing imperative to the pollution of surrounding environment.
Antiseepage processing is household garbage sanitary landfills addressing and builds one of the key factor that will consider, in the situation that there is no natural water barrier at the bottom of landfill yard, for preventing Landfill Leachate Pollution landfill yard and underground water around, need to take antiseepage to process to landfill yard.
The antiseepage pack processing of landfill yard contains horizontal leakage preventing and two kinds of forms of vertical seepage control.Newly-built refuse landfill the two essential one, also has two kinds of anti-permeation methods to be combined with its better effects if.
Horizontal leakage preventing refers to impervious barrier horizontal direction layout, prevents the downward osmosis pollution underground water of percolate.Horizontal leakage preventing can divide two kinds by lining, and a kind of is that natural antiseepage utilizes the clay liner at the bottom of landfill yard field to do antiseepage, and another kind is artificial antiseepage, utilizes artificial synthetic lining antiseepage.Vertical seepage control refers to that impervious barrier vertically arranges, prevents percolate osmosis pollution underground water towards periphery.The method is applicable to the Valley Type Landfill Site of independent geohydrologic unit, and underground water and surface water runoff can only be by surface flow to downstreams, mountain valley.Antiseepage curtain wall is the important way of vertical seepage control, and this technique belongs to chemical stabilization in ground is processed, and chemical stabilization can be divided into grouting, jet grounting and paddling process three classes conventionally.It utilizes cement grout, clay slurry or other chemical grout, by perfusion be pressed into, high-pressure injection or mechanical agitation, make slurries and cementing, to improve physics and the mechanical property of foundation soil.Current domestic this technology comparative maturity, anti-seepage effect is also fine, as soot, emperor ridge, Hangzhou adopts curtain grouting method.
At present, it is primary raw material that vertical seepage control technology adopts cement more, and the transmission coefficient of cement self is generally at 10-5~10-6cm/s, as easy as rolling off a log generation cup shake, and anti-seepage effect is unsatisfactory.After theing cement solidifies, be rigid body, easily fracture and damaged, has weakened water proof barrier performance greatly under external force, and reliability is not high, and difficulty of construction is larger, and construction costs is higher.
Therefore, need to invent a kind of seepage proof curtain structure of descending flexibly.
