Description
Technical field
The present invention relates to the Slope with multi-step anchor structure realizing rain dirt shunting, be particularly useful for the seepage control project of the solid waste landfill such as landfill yard, stope, Tailings Dam, Hui Chang, red mud dump, slag field having Slope with multi-step.
Background technology
Now China's solid waste landfill, to bank up etc. disposal time, the poisonous and harmful substance of storing up generation for a long time can enter soil in modes such as percolates, and direct consequence causes groundwater pollution.Seepage control project, for this situation of disposal of solid waste, avoids pollutant to enter earth's surface.Common impervious material mostly is based on HDPE antiseepage film, carries out anchoring at side slope place, ensures the steadiness of seepage prevention system.Inside at present relevant technical specification and standard, the anchor Design of slope anchored platform is: the impervious material of slope is laid to anchoring groove side 1/3 place far away, the impervious material extruding of upper side slope is soldered to above the slope impervious material on platform, this design can only be used for the individual layer leakage preventing structure of the HDPE antiseepage film only containing one deck, the structure containing multi-layer H DPE antiseepage film cannot be applicable to, i.e. multilayer leakage preventing structure.
Arrange the landfill yard of Slope with multi-step, stope, Tailings Dam, Hui Chang, red mud dump, slag field etc., place is comparatively large, more consideration rain dirt shunting.First, the anti-design of drainning off floodwaters such as Cut-off ditch, can improve the stability of reservoir area.Secondly, the sewage loads such as percolate can be reduced.And the dirty diversion design of the rain such as Cut-off ditch and anchoring groove when depositing, difficulty of construction is large, cost is high.
For above two problems, the Slope with multi-step anchor structure that the present invention's research realizes rain dirt shunting is necessary.
Summary of the invention
The technical problem to be solved in the present invention is for the solid waste landfill seepage control project of multilayer leakage preventing structure provides the Slope with multi-step anchor structure realizing rain dirt shunting, when waste height is less than plain stage of slope height as Cut-off ditch, be connected with storm sewer outside the venue, interception precipitation, prevents hillslope runoff from entering reservoir area; When waste height exceedes podium level, be incorporated to percolate process pipe network as percolate guide passage, improve the derivation ability of percolate.
The technical solution adopted for the present invention to solve the technical problems is: the Slope with multi-step anchor structure realizing rain dirt shunting, be applicable to multilayer leakage preventing structure, at anchoring groove, place is followed successively by from bottom to up: side slope substrate (1), sodium bentonite blanket (2), first floor HDPE antiseepage film (3), composite drainage network (4), second layer HDPE antiseepage film (5), non-woven geotextile (6), cast-in-situ concrete backfilling material (11), HDPE floral tube (9) and rubble guide layer (7).
Anchoring groove distance plain stage of slope edge >=800mm, impervious barrier material turning point is arcuate structure (8).
Anchoring groove width and highly all >=800mm, concreting height >=300mm bottom anchoring groove, form cast-in-situ concrete backfilling material (11).
In the anchoring groove both sides of cast-in-situ concrete backfilling material (11) top, pile up square brick topping (10) to podium level.
In anchoring groove cast-in-situ concrete backfilling material (11) top and both sides square brick topping (10); place HDPE floral tube (9); lay rubble guide layer (7) to podium level; at the non-landfill of heap body to being used for guide rain flood during podium level, be used for guide percolate when piling on body landfill to platform.
The impervious barrier material-paving of upper side slope is above slope impervious barrier material, integrally welded after anchoring groove overlaps with upper plain stage of slope place.
The beneficial effect that the present invention is arranged is: for the solid landfill seepage control project containing Slope with multi-step anchored platform, design a kind of multilayer leakage preventing structure also anchor structure applicatory, realizes rain dirt shunting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Fig. 1 is the Slope with multi-step anchor structure cross-sectional schematic that the present invention realizes rain dirt shunting.
1. side slope substrates, 2. sodium bentonite blanket, 3. first floor HDPE antiseepage film, 4. composite drainage network in figure; 5. second layer HDPE antiseepage film, 6. non-woven geotextile, 7. rubble guide layer, 8. arcuate structure; 9.HDPE floral tube, 10. square brick topping, 11. cast-in-situ concrete backfilling materials.
Detailed description of the invention
The present invention realizes the Slope with multi-step anchor structure of rain dirt shunting, excavation and anchorage ditch in Slope with multi-step anchored platform, width >=800mm, highly >=800mm.
After basal plane acceptance(check), in side slope substrate (1) upper laying two-layer barrier structure, from bottom to top be followed successively by: sodium bentonite blanket (2), first floor HDPE antiseepage film (3), composite drainage network (4), second layer HDPE antiseepage film (5), non-woven geotextile (6).
The two-layer barrier structure of slope, from the platform place near upper side slope toe, to lay to anchoring groove backward upper laying platform downwards and then to slope, leakage preventing structure all adopts arcuate structure (8) in turning point, anchoring groove both sides.
Laying anchoring groove underfill cast-in-situ concrete backfilling material (1) of two-layer barrier structure, concreting height is not less than 300mm.
The impervious barrier structure overlap joint of upper side slope is above the slope impervious barrier at toe platform place, integrally welded.
In inner cast-in-situ concrete backfilling material (1) top of anchoring groove, along anchoring groove both sides, pile up width square brick topping (10) to flushing with slope anchorage platform.
HDPE floral tube (9) is placed in the groove that square brick topping (10) and cast-in-situ concrete backfilling material (11) are formed.
Rubble guide layer (7) is filled up in the anchoring groove laying HDPE floral tube (9).
When solid waste landfill height does not arrive podium level, be connected by HDPE floral tube (9), as Cut-off ditch, retain slope head flowing water with drainage system outside the venue, guide surface flow and surperficial rain flood, reduce percolate treating capacity.
Time above solid waste landfill to platform, refuse of banking up after leakage preventing structure is laid sand pocket, is connected HDPE floral tube (9) with percolate guide system, for piling the percolate of body above guide.
