Protection after the completion of laying is highly important engineering measure in household refuse landfill sites running.
Refuse landfill needs to consider the influence of level of ground water in construction, also, especially in rainwater weather, subsurface flow
Amount increase, water level goes up, and underground water is accumulated in antiseepage film bottom and produces certain pressure, causes antiseepage film bulge, when serious
The whole seepage control system that landfill yard can be destroyed causes percolate to leak, and groundwater resources are polluted.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of landfill site seepage prevention structure,
In influence of the reduction underground water to seepage control system so that landfill yard runs safer stabilization.
To achieve the above object, the utility model provides following technical scheme：A kind of landfill site seepage prevention structure, including fill out
Bury place；The landfill place, which includes, is provided with antiseepage film in impervious barrier, impervious barrier；Led provided with percolate on the impervious barrier top
Fluid layer, the impervious barrier bottom is provided with underground water guide system, and the underground water guide system includes being located at below antiseepage film
Underground water guide layer at 1.5m, the underground water guide layer is connected with several sumps, the sump provided with diving
The liquid-level switch that pump and control immersible pump are opened and closed, in addition to drainpipe, described drainpipe one end are connected with immersible pump, the other end
Extend to beyond landfill place.
By using above-mentioned technical proposal, the utility model can be by groundwater level control apart from below antiseepage film 1.5m
Safety level position；By setting the sump being connected with underground water guide layer, the ground for the water guide layer that permeates the ground is collected
Lower water, when WIH position of catchmenting, which exceedes liquid-level switch, sets water level, the underground water in sump is passed through row by pump work of diving under water
Water pipe detaches landfill place, using the program, can effectively control the water level of underground water, reduces Groundwater infiltration impervious barrier, so that
Avoid antiseepage film to be extruded by underground water, play a part of protecting antiseepage film so that refuse landfill is operationally more pacified
It is complete stable.
The utility model is further arranged to：The underground water guide layer includes metalling and the both sides above and below metalling
Geotechnological nonwoven layer.
By using above-mentioned technical proposal, the water conservancy diversion covered conduit of metalling formation underground water is provided simultaneously with filter capacity so that
Silt is difficult to be discharged into sump；And the geotechnological nonwoven layer of both sides can be used for the soil of upside above and below filtering metalling above and below metalling
Matter, it is to avoid the soil property of both sides is mixed into underground water and is discharged into sump above and below metalling, reduces soil property and is lost in.
The utility model is further arranged to：Filter is provided between the underground water guide layer and sump.
By using above-mentioned technical proposal, filter can be used for that will flow into the further mistake of underground water of sump
Filter, it is to avoid rubble and silt are discharged into sump.
The utility model is further arranged to：The impervious barrier also includes the argillic horizon for being located at both sides above and below antiseepage film.
By using above-mentioned technical proposal, argillic horizon can be complementarily shaped to composite anti-penetrating water construction with antiseepage film, play
The water-impervious effect of effect, and enable antiseepage film to bear bigger load, improve anti-pressure ability.
The utility model is further arranged to：The percolate guide layer includes cobblestone layer and above and below cobblestone layer
The geotechnological layer of cloth of both sides.
By using above-mentioned technical proposal, cobblestone has the characteristics of hardness is high, drainage performance is excellent, can bear big pressure
Power, improves the structural stability in landfill place；Cobblestone layer above and below both sides geotechnological layer of cloth can to cobblestone layer both sides soil property
Obstructed, reduce both sides soil property and be lost in so that percolate guide system is not easily blocked.
The utility model is further arranged to：The sump is formed by concreting.
By using above-mentioned technical proposal so that sump structural strength is high, is less prone to and collapses.
The utility model is further arranged to：Agitating device is provided with the sump.
By using above-mentioned technical proposal, agitating device can be stirred to the underground water in sump so that impurity can
To detach sump with drainpipe, reduce impurity in sump and deposit.
In summary, compared with prior art, the utility model can control groundwater level under safety level, so that
Influence of the underground water to antiseepage film is reduced, the stability of leakage preventing structure is improved.
