Abstract
The utility model relates to an anchoring system for the closure overlapping layer of a refuse landfill. The utility mode aims to provide an anchoring system for the closure overlapping layer of the refuse landfill. The aim of anchoring is realized while continuous smoothness of a closure draining system is ensured. The technical scheme is as follows: the anchoring system for the closure overlapping layer of the refuse landfill is characterized in that a flood stopping pitch is arranged around a garbage pile body; two layers of geotextile composite draining nets are overlapped at the top of the garbage pile body; two layers of geotextiles are cushioned between the two draining nets; an seepage-proofing membrane is arranged between the two geotextiles; and a soil layer is overlapped at the top of the geotextile composite draining nets. The anchoring system is characterized in that the geotextiles and the seepage-proofing membrane extend to the flood stopping pitch and are fixed at the inside wall of the flood stopping pitch by anchoring bolts; a circle of concrete hollow bricks are arranged at the outermost periphery of the soil layer; concrete blocks are pressed on the top of the concrete hollow bricks; and a cobble reversed filtered layer is arranged between the concrete hollow bricks and the soil layer. The anchoring system for the closure overlapping layer of the refuse landfill is suitable for the engineering of refuse landfill of city life.
Description
Technical field
The utility model relates to a kind of refuse landfill sealing covering layer anchor system.Be applicable to the city life garbage landfill engineering.
Background technology
Anchoring for the closing leakage preventing structure in " Sanitary Landfill closing tecnical regulations " CJJ112-2007 has following regulation: " lay geomembrane and answer firm welding, reach intensity and the antiseep requirement of regulation, meet corresponding inspection of quality standard; When the larger side slope of the vertical discrepancy in elevation is laid geomembrane, anchored platform should be set, the platform discrepancy in elevation should not be greater than 10m." these regulations are the way with reference to the impervious barrier anchoring of bottom of the reservior, landfill yard new field substantially, and not for the special construction closed, especially close periphery with cut a Great Gulch commissure place and do specific (special) requirements.
At present, household refuse landfill sites Closure cover layer anchor system is also generally with reference to landfill yard bottom antiseepage film anchor type.As shown in Figure 1, at junk-heap body 1 periphery, be provided with and cut Great Gulch 2, junk-heap body 1 top covers two-layer soil engineering composite drainage network 4, between two drainage networks, be lined with two-layer geotextiles 5, sandwiched antiseepage film 6 between two geotextiles, geotextiles and antiseepage film extend to cut in Great Gulch and in cutting Great Gulch fixedly geotextiles and antiseepage film of packing material, after anchoring, a reserved drainage channel is as the rear gutter that closes, soil engineering composite drainage network 4 top overlying soils 3.Such anchor type, have two larger problems: 1, anchor system has taken the cross-section of river of section Great Gulch, and reserved drainage channel is difficult to meet the needs of closing rear perimeter edge massif and heap surface draining; 2, anchor system has only been considered the anchoring of earth working material, for the processing that do not fix of closing the superiors overlying soil, when rainy, very easily occurs running native phenomenon, causes running soil and directly falls into and cut a Great Gulch, stops up and cuts a Great Gulch.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of refuse landfill sealing covering layer anchor system of simple in structure, easy construction, the drainage system of guaranteeing to close when realizing the anchoring purpose continues unimpeded.
The technical scheme that the utility model adopts is: a kind of refuse landfill sealing covering layer anchor system, at the junk-heap body periphery, be provided with and cut Great Gulch, the junk-heap body top covers two-layer soil engineering composite drainage network, between two drainage networks, pad is established two-layer geotextiles, sandwiched antiseepage film between two geotextiles, described soil engineering composite drainage network top overlying soil is characterized in that: described geotextiles and antiseepage film extend to cut in Great Gulch and through anchor bolt and are fixed in and cut the Great Gulch inside wall; Described soil layer outermost arranges a circle concrete hollow block, and the concrete hollow block top is pressed with concrete block, between described concrete hollow block and soil layer, is provided with the cobble loaded filter.
Geotextiles is partly wrapped in the described concrete hollow block outside.
Liner, geotextiles, antiseepage film, another layer geotextiles, another layer liner, the flat flat steel bar of stainless steel and stainless steel gasket are installed on described anchor bolt from inside to outside successively, and are tightened through the stainless steel nut.
Described anchor bolt spacing 80 ~ 100cm.
The beneficial effects of the utility model are: the utility model is simple in structure, easy construction, and geotextiles, antiseepage film are fixed in and cut the Great Gulch inside wall through anchor bolt, does not take and cuts the Great Gulch cross-section of river, does not affect and cuts the Great Gulch discharge capacity.In the soil layer periphery, cobble filtration beds and concrete hollow block are set, play fixedly soil layer, prevent from running native effect, moisture in soil layer can infiltrate by the hole of hollow brick and cut Great Gulch on the other hand, the cobble french drain of brick inboard and geotextiles can play the effect of anti-filter, if meet when raining heavyly, surperficial rainwater on the soil layer concrete block of can jumping over directly enters and cuts a Great Gulch, not there will be the phenomenon that blocks water.
The accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of embodiment.
Fig. 3 is the A-A sectional view of embodiment.
The specific embodiment
As shown in Figure 2 and Figure 3, the present embodiment is old Closure cover layer anchor system of a kind of refuse landfill, mainly concrete perforated brick, anchor bolt, cobble loaded filter etc., consists of.The present embodiment cuts Great Gulch 2 junk-heap body 1 periphery setting, and junk-heap body 1 top is coated with two-layer soil engineering composite drainage network 4, and establishes between geotextiles 5, two geotextiles and also be folded with antiseepage film 6 at pad between two drainage networks.Geotextiles 5 and antiseepage film 6 extend to cut in Great Gulch 2 and through anchor bolt 13 and are fixed in and cut Great Gulch inside wall (by junk-heap body 1 side) above, do not take cut Great Gulch 2 cross-sections of river fully.In this example, anchor bolt 13 adopts expansion bolt, spacing 80 ~ 100cm, anchor bolt 13 passes liner 8, geotextiles 5, antiseepage film 6, another layer geotextiles 5, another layer liner 8, the flat flat steel bar 9 of stainless steel and stainless steel gasket successively, finally with the stainless steel nut, is tightened.
In the present embodiment at the soil engineering composite drainage network 4 top overlying soils 3 of the superiors, soil layer 3 outermost arrange a circle concrete hollow block 11, hollow brick partly wraps geotextiles, and (hollow brick removes away from soil layer 3 sides, all the other all coat geotextiles), concrete hollow block 11 tops are pressed with concrete block 12, between concrete hollow block 11 and soil layer 3, are provided with cobble loaded filter 10 in addition.This structure can play fixedly soil layer on the one hand, prevent from running native effect, moisture in soil layer can infiltrate by the hole of hollow brick and cut Great Gulch 2 on the other hand, the cobble loaded filter 10 of brick inboard and geotextiles can play the effect of anti-filter, if meet when raining heavyly, surperficial rainwater on soil layer 3 concrete block 12 of can jumping over directly enters and cuts a Great Gulch 2, not there will be the phenomenon that blocks water.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
