Description
Technical field
The invention belongs to the garbage disposal field, be specifically related to rubbish landfill and with the guide of refuse landfill sewage.
Background technology
Get into after 21 century, urbanization process is constantly accelerated, and city size enlarges rapidly.The refuse landfill of building the outer suburbs in the past in becomes the outskirts of a town, city gradually also along with the expansion in city.Along with increasing gradually of peripheral population, dwelling house, factory, landfill yard is increasing to the influence of peripheral economy and environment.Simultaneously, the quantity of refuse cumulative year after year has been brought no small pressure and difficulty to landfill work.Under such form, innovate landfill process, cut operating costs, reduce influence, improve the landfill intervention level and become the only way that sustainable development is walked in refuse landfill now surrounding enviroment.
At present the garbage loading embeading technology that extensively adopts of institute is: the temporary road that rubbish metering → piece stone is laid and dump platform → push away concora crush reality → clay covering.Improve constantly along with the development of society and to what landfill operation required, the shortcoming that traditional coverage mode exposes is also more and more.
At first, adopt building stones to lay rubbish and dump platform, the material of building stones is had relatively high expectations, in conjunction with seasonal variations, the laying of building stones requires also different.The value that the building stones platform just has no after using basically reuses also difficultly, can be regarded as disposablely, has promptly taken storage capacity, has wasted resource again.
Secondly, clay is disposable material, can not utilize again.And on buying, to pay a very big expense, and improved operating cost, taken storage capacity greatly, account for 10～12% of landfill storage capacity, reduced the service life of landfill yard.Stir up a cloud of dust if run into the dry weather of strong wind, it is then more abominable to run into the rainy day environment, and road is muddy to can't bear.Greatly reduce operating efficiency, the operating environment of integral body is caused have a strong impact on.Also other links in the landfill operation many negative influences have also been produced with the soil covering.
Once more, existing technology is prone to produce the sewage guide and has some setbacks, and causes often having sewage to accumulate in the surface around the operating area, reservoir area, time one long at once with rubbish in percolate ooze mutually, send unpleasant penetrating odor, the environment around having influenced greatly.
Show according to the retrieval of interrelated datas such as Chinese patent net, except " emperor mountain range garbage loading embeading working system " that the inventor applied for, do not see other relevant reports as yet at present about this working system.
Summary of the invention

The specific embodiment
Plate platform, road are made
Compacting is carried out on basis to platform and road: the basis of platform and road is the rubbish of landfill; Be the sinking speed that guarantees road and platform in running garbage areas less than periphery; Avoid causing road and platform to be lower than peripheral plane; Common waste layer rolls (bull-dozer 5 times) 3 times back and forth with compacting machine, must roll (or bull-dozer rolls more than 10 times back and forth) more than 5 times once more back and forth with compacting machine as platform and the basic waste layer of road.
Basal layer is flattened: garbage truck re-uses excavator later on compacted region is flattened, and rugged phenomenon is dug clearly and is filled up, for the later stage steel plate is laid ready.Road and platform should be than more than the high 0.2m in neighboring area, prevent that sewage from building up below road and platform.
Carry out the laying of steel plate subgrade case: the steel plate subgrade case is laid by excavator.At first lay backing plate, be generally the steel plate of 4m * 1.5m, seamless linking to each other between the backing plate.On backing plate, lay roads plate, landing slab then, reach port plate.Steel plate misplaces up and down at process of deployment light plate and steel plate and interlocks, and connects with " U " type screw or steel wire rope etc. between the steel plate, reduces the displacement situation that steel plate in use occurs, thereby reduces the slit of road and platform centre.
The plate platform operational method
There are a plate platform and an interim emergent platform in the reservoir area.Plate platform has 6 refuse dump truck positions; Each parking stall guarantees that all an auxiliary worker commands and assistance is toppled over;, vehicle ' is responsible for opening the back car bonnet after putting in place; Be responsible for the remaining rubbish of garbage truck peace you mouth is in time cleared up toppling over the back that finishes, keep smooth and clean and tidy on the platform constantly.Vehicle turnover platform has the special messenger to command, and guarantees the orderly running of platform.Being equipped with machinery during operation has: 3～5 bull-dozers, 1～2 excavator and 1 compacting machine.Each rubbish dumps port and is equipped with 1 bull-dozer, the platform port is dumped the rubbish that gets off clear up, pave; Be equipped with 1～3 bull-dozer on the scope of operation, the rubbish on the scope of operation is carried out paving operation and slope operation; Compacting machine carries out compacting operation; Excavator can according to circumstances dig the rubbish below the platform earlier and be transported to other place, carries out paving operation with bull-dozer again, both can ensure that the rubbish of the platform below scope of operation can not piled up, and can also in time repair plate platform simultaneously.
The concrete work flow that film covers
Compacting, smooth: at first, the scope of operation usage mining machine that puts in place carries out roughly smooth of whole plane, and main purpose is whole plane to be made the oblique gesture of a water guide, and repair in the not enough or too much zone of rubbish to rubbish simultaneously; Secondly, the scope of operation that trims is carried out compacting, carry out compacting operation (bull-dozer rolls 5 times back and forth, and compacting machine rolls 3 times back and forth), under the situation that has personnel to exercise supervision, carry out compacting with excavator near the zone of antiseepage film side slope with pushing to machine or compacting machine; At last, use digging machine bucket or special-purpose compacting head,, guarantee that the surface does not have hard material, so that the paving of film the compacting leveling that the rubbish surface becomes more meticulous.
Paving of HDPE film: the size of HDPE film is 6m * 50m generally speaking, can just carry out reasonably vertical or horizontal paving according to the shape size and the landform of overlay area when paving.Reasonably paving not only can be time saving and energy saving, can also practice thrift the use amount of HDPE film.Earlier the HDPE film of rolling is placed on an end of wanting the overlay area when paving, the staff spreads the HDPE film out together to the other end then, until film use up or the regional end that paves till.The overlapping of 10cm～15cm arranged between film and the film, be used for the welding between the film.
Weld, press solidly: through heat welded, guarantee to weld free from flaw between film and the film, welding edge should be consistent with water (flow) direction along the position.Geotechnological cloth bag is used in pressing solidly of reservoir area marginal membrane, keeps seamless between bag and the bag.Above the zone line film, put junked tire and blown away by wind preventing, the spacing between no matter each tire is gone, is listed as is 10m.
The shunting of removing contamination
Remove contamination and shunt the manufacture craft of ditch: ditch middle berth HDPE film, the top guide clear water of film, the below guide sewage of film.When making, at first dig and establish one and spread the thick stone in the 0.5m left and right sides then deeply for the irrigation canals and ditches about 1m, the useless film in stone upper berth carries out liner, then on old film, lays the HDPE film that covers, and the top of film also demonstrates one and is the irrigation canals and ditches of 0.5m deeply like this.Can in stone, bury the HDPE pipe underground according to the size of sewage quantity simultaneously, strengthen the guide ability of sewage.Here being noted that, in order to prevent the film wearing and tearing mixed flow of the time removing contamination, laying old film and carry out liner key very, is not omissible step.
The making flow process of " hump ditch ": is " waste dam " about 1 meter earlier piling up the twice height on the rubbish plane, at the bottom of two dams between horizontal range be 0.4m, horizontal range is 0.8m between two dam crests, forms trapezoid-shaped trench.At the bottom of inboard dam, outwards lay the HDPE film then, the bottom, HDPE film dam on both sides is divided overlapping, adds a cover an old HDPE film after having laid the HDPE film of new shop is protected.Fill out the thick stone in the 0.2m left and right sides after having spread, on stone, lay the HDPE pipe of Φ 200mm or Φ 400mm, and then spread stone, stone is taped against apart from dam crest 0.2m and gets final product.
The laying of french drain and the guiding of sewage: the reservoir area sewage quantity is predicted, thereby more reasonably laid french drain.Owing to when preceding one deck operation, carried out the laying of main french drain in advance, so when operation, only need prop up digging to establish and getting final product of french drain and french drain temporarily.Intersection at french drain can establish vertical vertical shaft, leads to the blow-off line of bottom of the reservior.Interim french drain is to dig according to the different times sewage quantity to establish, and the son that can only rockfill is not buried the HDPE pipe underground, can practice thrift cost and time like this.And whether these interim french drains can also dig at peak value according to sewage quantity at that time and establish, thereby increase this regional sewage guide ability, forms the regional guide net of a prosperity.Use the HDPE pipe of Φ 400mm in the main generally speaking french drain, use the HDPE pipe of Φ 200mm in the french drain; On guiding, earlier the scope of operation is pressed dividing elements, the smooth reservoir area scope of operation is formulated surface tilt gradient operation or work standard according to actual conditions.
