The end face polishing device for the workpiece has a simple structure, the stability in use is good, adopt the compound native particulate overburden of biological charcoal, it has good storage capacity, be favorable to forming the capillary attraction effect, thereby the effectual rainwater that prevents infiltrates contaminated site, simultaneously its in also can effectual reductions contaminated site gaseous pollutants discharge and reduce oxygen entering contaminated site in the atmosphere, reducing pollutants place environment negative effect, and it can effectually save coarse grain earth material quantity, and greatly reduces the operation cost, the double -switching capacitance compensating device has high applicability, therefore, the clothes hanger is strong in practicability.
Description
Technical field
The utility model belongs to contaminated site seepage-proof structure technical field, is specifically related to a kind of percolation-proof capillary shielding harness for contaminated site.
Background technology
The contaminated sites such as solid wastes landfill site, contaminated soil and mine tailing, major pollutants are divided into inanimate matter pollutant, SOM pollutant and volatile contaminant.Soluble pollutants can with rain infiltration underground water, polluted underground water; Volatile contaminant is diffused into air, pollutant atmosphere.Therefore, contaminative place original position is administered not only to be needed to prevent rain infiltration contaminated site, and decreasing pollution gas (CH4) is discharged and reduction atmospheric oxygen enters contaminated site, soil layer covering system administers effective means as contaminated site, is applied widely.The purpose of design of soil layer covering system is that in preventing pollution place, pollutant directly affects environment, and as in soil, dissolved contaminants enters underground water, or volatile Pollutants Diffusion is in air, and covering layer need be conducive to the migration controlling liquid phase vapor phase contaminants.Conventional soil layer covering system comprises: clay covering, the covering of geosynthetics clay and living beings cover, and often kind covers its advantage existing, also have it not enough, as effectively can not reduced rain infiltration, easy generation season cracking and being unfavorable for reducing gas diffusion etc.Capillary retarding system is the double-deck soil layer covering system be placed in by fine grained soils on coarse-grained soil, under utilizing unsaturated state, fine grained soils becomes capillary attraction effect with the unsaturated soil poor permeability abnormity of coarse-grained soil, under capillary attraction effect, water is stored in particulate soil layer, is seeped into contaminated site under retained water further.Although capillary retarding system overcomes the defect of other overlying soil system, also have its weak point, such as particulate soil layer storage capacity is limited, affects capillary retarding effect and is formed; Coarse-grained soils limited source etc.Therefore, suitable particulate layer material need be found, capillary retarding system both played and prevents rain infiltration, have q.s to store to the rainwater infiltrated again, to reduce exhaust gas diffusion and to plant layer demand of plant growth for place in future.Meanwhile, coarse-grained soil alternative materials is found, to reduce coarse-grained soil consumption and capillary retarding system thickness.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model is to provide that a kind of structure is simple, stability in use good and the percolation-proof capillary shielding harness for contaminated site that applicability is strong.
The technical scheme realizing the utility model object is a kind of percolation-proof capillary shielding harness for contaminated site, comprises the composite earthwork synthesis packed layer be arranged on directly over contaminated site and the charcoal composite earth particulate covering layer be arranged on directly over described composite earthwork synthesis packed layer.

The filling earth material that described charcoal composite earth particulate covering layer comprises biological plastid particle and is filled between raw plastid particulate interspaces.
The mass ratio of described biological plastid particle and described filling earth material is 1:10 ~ 1:20.
Described biological plastid particle is that forest deadwood leaf or stalk are pulverized and formed after anoxic or few oxygen pyrolysis.
Described filling earth material is cohesive soil or sandy soil.
The tectal thickness of described charcoal composite earth particulate is greater than 30cm.
Wherein, band drain is that the salient point (or hollow cylindrical porous) making circular cone convex or stiffening rib through punching press by polystyrene (HIPS) or polyethylene (HDPE) plastic cement base plate forms, and fabric width has 3 meters, and length has 10 meters or 15 meters.
Geotextiles, also known as geotextile, it is by the water permeability geosynthetics of synthetic fibers by acupuncture or braiding.Geotextiles is new material geosynthetics one wherein, and finished product is cloth-like.
The utility model has positive effect: structure of the present utility model is simple, stability in use good, adopt charcoal composite earth particulate covering layer, it has good storage capacity, be conducive to forming capillary attraction effect, thus effectively prevent rain infiltration contaminated site, simultaneously its also can effectively in decreasing pollution place dusty gas to discharge and reduction atmospheric oxygen enters contaminated site, reduce contaminated site environment negative effect, and it can effectively save coarse-grained soils consumption, greatly reduce construction cost, applicability is good, practical.
