Abstract

The invention relates to a novel refuse landfill covering method. Garbage and waste are covered with sheets after the garbage and the waste are buried or dumped. Waste can be dumped on the sheets without removing the sheets, or the sheets can be moved and reutilized. The best material for covering waste sediments is a braided object with biodegradability and permeability, such as burlap. When a large number of the sheet covers are applied, the sheets can be arranged one next to another, and can also be connected by seaming, binding, stapling or rivet fixation, and the like.

Description

A kind of garbage landfill yard covering method

Technical field

The invention relates to the method for refuse, rubbish and other material landfill.Specifically relate to the burying method of rubbish after landfill yard, rubbish heap, refuse and the ground such as soot and mining site are processed.

Background technology

Junk need hide reason have following some:

(1) in order to reduce the disperse of the smell of junks such as rotting;

(2) avoid parasite and fly grow and birds come this and look for food;

(3) that avoids wind to be scraped in soot etc. is in disorder;

(4) aesthetic in the place such as refuse landfill.

In the real work of nowadays refuse landfill, every day hides landfill yard once in a while, and such as night just could not hide.Further, some non-renewable mineral resources of current main employing are used to daily junk covering.Some local application clay as overcover, but differs due to itself granular size, the factors such as poor ductility, and as providing effective covering, the thickness of clay can not lower than 200mm.The numbers of plies such as the rubbish processed of next day, at capped one deck clay, goes down day by day, junk-overcover-junk-overcover get more and more, and permeability worse and worse.Finally, the corrupt smell of junk cannot be got rid of, and must take other method process.

The daily drawback of junk overcover application mineral as clay etc. is as follows:

(1) mineral itself have using value, non-renewable, and application mineral are a kind of wastes;

(2) for some galvanic wastes, showing cannot be completely covered, and residual space is a kind of potential harm;

(3) if covering has impenetrability, so a waste pit can be divided into several relatively little, respective independently sub-space by it, because these little spaces feature is separately different, does not possess homogeneity, is difficult to long-period of management;

(4) if daily covering has impenetrability, so junk covers the gas of generation for a long time, liquid cannot outflow, and affects the ground stability such as soot.

Summary of the invention

The invention relates to the method for the covering of refuse, rubbish or other materials daily.Junk is usually toppling in layer, and every interlayer covers one deck braiding tablet or non-establishment tablet, and one deck junk capped after, before lower one deck rubbish is toppled over, overcover is left over or is withdrawn and is all fine.

Before lower one deck refuse, rubbish or other materials carry out this process, covering can first be withdrawn, and now covering is to provide temporary transient covering effect; Covering also can be left over so far, and junk is toppled on it, forms junk-covering-this form of junk-covering, namely constitutes junk layer pile structure.Have more, the covering mentioned in the present invention can be withdrawn and be reused, until covering can not be employed again before lower one deck junk is toppled over; And if do not remove covering, junk can directly be toppled on it, and covering needs to be removed never.

Covering should be selected to have infiltrative, so that after junk layer by layer and covering deposition, the liquids and gases that corrupt rubbish produces can be got rid of instead of push at every one deck.For each junk, covering can be that the arrangement of multiple tablet hides, and also has by sewing up stitch in covering after coupling together.Therefore, the liquid that the cover stock material that the present invention selects allows refuse rubbish to produce and rain penetration, these liquid or rainwater also can pass through in the junction of fragment covering.

In addition, sheet coverings itself should have biodegradability.Sheet overcover area is relatively large, can hold lid junk, and its structure is netted or latticed.Generally, the space of mesh blanket can not be larger than the average-size of junk to be hidden or space is little can not freely pass through to parasite, and whatever gap value is less, and the maximum interspace selected is no more than 12.5cm.

New sheet coverings is a volume, can with hauling machine, other tool of unloading traction be laid in junk surface.The utensil that on sliding machine or tractor, direct or indirect design and installation one is such can dragged.With cross covering also by hauling machine, tool of unloading or manpower, it can be removed above junk, be wound on a club, so as with again apply.

Sheet coverings preferably selects gunny cloth, because it has biodegradability and cheap.And gunny cloth also can be soaked into by water or chemical substance as required or dye.Other can apply sheet coverings must have the performance similar with gunny cloth, as P.V.C. net, P.V.C. sheet, canvas, mat and burlap etc.

When multi-disc covering is applied simultaneously, can interconnect or directly edge flanging edge placement by sewing up stitch, as the case may be, above it, some weights can be put in case overcover moves.These are sewed up stitches or fixing preferably to disassemble than being easier to, so that covering reapposing when applying, sewing up, connection etc.

Detailed description of the invention

Process in the usual hollow place on the ground of refuse rubbish, the refuse landfill namely often said.Fig. 1 is refuse landfill, and in this figure, " 1 " is a hollow place, and " 2 " are antiseepage line (non-equal proportion).This refuse landfill can take up an area several hectares.

For the ease of landfill, hollow place " 1 " should be divided into multiple little region.Each region can pile up the position of rubbish to horizon " 3 " layer by layer, then enables next cut zone.The every one deck of usual title is a ladder, and is become ladder by adjacent material buildup layer by layer in cut zone.Region 4 as shown in Figure 1 and region 5 are filled, and the stage is filled in region 6.Region 4 is piled up for ladders such as 4a, 4b and is formed from bottom; Region 5 is piled up by ladder 5a, 5b and is formed.

Each region surface hides one deck tablet the whole night, and before the refuse garbage loading embeading of second day, covering is preferably removed.Generally, the nearly 2m of refuse waste layer of a day is dark.Figure 2 shows that the top plan view in a landfill region after segmentation, is the state being covered with covering night.Covering has some rectangular patch thing " 15 " jute seats to form, they directly can be placed by edge flanging edge, also can at edge go out sew up, link together.Instrument " 16 " is for sprawling cladding material, and last section of cladding material " 17 " pulls down from the cladding material " 18 " of entire volume, complete as shown in the figure.When completing the work use sprawling cladding material, this instrument is not finally withdrawn.

The edge of each block sheet coverings can link together, and as shown in " 14 ", but is that mechanical stitch connects, and during to ensure daily covering junk, each section of covering all can not shift position and expose rubbish.The work of this connection can be completed by manual suture sewing machine, also has automation.But which kind of mode don't work, all must ensure that the line sewed up is easy to be removed, and these coverings can also be utilized again, again can be sewed up, be connected and fixed.

Figure 3 shows that instrument is sprawled in the flaky cladding material distribution that the present invention is correlated with.It is made up of a large framework " 20 " and the material webs above it " 25 ".One end of flaky material " 17 " is still being sprawled on instrument, and this instrument dilatory can make cladding material move along set direction to sprawl.

Sprawl instrument with tractor or the dilatory cladding material of Sledge type machinery, this can make bedding effect and operating efficiency greatly improve with design.Certainly, if bedding material is new, from covering, the operation discharging bedding material above volume is simpler and easy.As shown in Figure 4, if cladding material has been laid between two-layer rubbish, refuse or other materials, has been rolled from one end of cladding material with a pole, then rolled all coverings along refuse surface.One section of sheet coverings " 15 " or " 15a " end are fastened on drag-pull cart, travel dilatory covering (as shown in Figure 4 b), or dilatory sheet coverings hide junk (as shown in fig. 4 a) to sprawl on junk " 30 " surface.The cladding material hiding garbage fees thing should comparatively robust, can bear the active force of certain load.In application process, damagedly because the instrument of application in work, junk below or other materials etc. destroy can form duck eye once in a while, this is not problem, these breakages can be repaired, sew up yet.

After a landfill yard fills up junk, its surface usually hides one deck and does not have a covering of material of permeability.Some natural materials can be applied as clay, or the material of hypotonicity, also can apply highdensity polythene material, covering overlays soil again, this panel region can be made to re-use, as being used as to plough.Under normal circumstances, the material of finally adding a cover must be hypotonicity, can reduce the infiltration of rainwater and distributing of gas like this.Meanwhile, also must have high-quality, high strength, can pull with machine tool tractive in the work such as bedding and all can not cause damage, and these materials also should have biological non-biodegradable.On the contrary, for the covering between the junk below it, viewpoint of the present invention is thought without the need to possessing above-mentioned performance.
