Abstract

The utility model discloses a kind of gas drainage device covered temporarily for household refuse landfill sites, the household refuse landfill sites have junk-heap body, the junk-heap body top is equipped with clay layer, the interim cover layer of the clay layer top laying, the gas drainage device includes gas guide bend pipe, the gas guide bend pipe includes integrally formed straight floral tube and the reality pipe with elbow, the straight floral tube is inserted in clay layer and junk-heap body, the real pipe with elbow is in clay layer top, and the real pipe with elbow and the interim cover layer contact position sealing of gas.The utility model can be effectively under the interim cover layer of guide household refuse landfill sites produced by junk-heap body landfill gas, air accumulation forms gas bag under avoiding interim cover layer, reduce in interim overwrite procedure and landfill yard operation in potential safety hazard, when gas production meets requirements of comprehensive utilization, multiplex utilization facilities are sent to after can landfill gas be collected.

Description

A kind of gas drainage device covered temporarily for household refuse landfill sites
Technical field
The utility model is related to a kind of gas drainage device, and more particularly to one kind is covered temporarily for household refuse landfill sites Gas drainage device.
Background technology
What Sanitary Landfill was mainly received is house refuse, and some organic principles in house refuse are passing through Prolonged fermentation will produce substantial amounts of landfill gas after decomposing, main component therein is CH4And H2S, CH4For flammable Gas, H2S has foul odour, so in order to avoid the unordered discharge of landfill gas causes to have a strong impact on to environment, while being also Preventing rainwater from entering junk-heap body turns into percolate, life junk-heap body is covered temporarily using HDPE film, but face When covering after, the landfill gas in junk-heap body cannot be naturally drained, and cause fuel gas to be assembled under film, thus in the presence of one Fixed potential safety hazard, to form to realize the comprehensive utilization of the landfill gas of interim covering system and avoiding landfill gas from assembling Dangerous larger gas bag on interim covering system, it is necessary to set gas guide system.
Utility model content
In order to landfill gas are assembled to form gas bag in solving the problems, such as interim covering system, the utility model provides a kind of using In the gas drainage device that household refuse landfill sites are covered temporarily, guide can be realized to landfill gas, be suitable to environmental protection.
The utility model provides a kind of gas drainage device covered temporarily for Sanitary Landfill, the life Refuse landfill living has junk-heap body, and the junk-heap body top is equipped with clay layer, the clay layer top laying HDPE Film, the gas drainage device include gas guide bend pipe, the gas guide bend pipe include integrally formed straight floral tube and Reality pipe with elbow, the straight floral tube is inserted in clay layer and junk-heap body, and the real pipe with elbow is in glutinous Soil layer top, and the real pipe with elbow and the interim cover layer contact position sealing of gas.
The interim cover layer is HDPE film.
The outer wrap of the straight floral tube has non-woven geotextile.
The grammes per square metre of the non-woven geotextile is 200-600g/m2, the non-woven geotextile encloses in the outside of straight floral tube and sets Height be 0.5-1m, it is 0.2m to enclose the width for setting.
The thickness of the clay layer is 200mm-500mm.
The straight floral tube is equal with the internal diameter of the real pipe with elbow.
It is the HDPE floral tubes of 50-100mm that the straight floral tube uses internal diameter.
The height of the straight floral tube is 0.5-1m.
The real pipe with elbow uses internal diameter to be managed in fact for the HDPE with elbow of 50-100mm.
The whole height of the real pipe with elbow is 0.2m, and wherein the height of elbow is 0.1m.
The utility model has the advantage of:
1st, can be with the interim cover layer in interim covering system(HDPE film)Realize welding, it is ensured that whole interim covering system The antiseepage rain dirt diverter function of system.
2nd, effective guide of landfill gas can be realized, interim cover layer in interim covering system is prevented(HDPE film)Lower gas Body is assembled to form gas bag, reduces the potential safety hazard in landfill yard operation.
3rd, can subsequently be combined using facility with landfill gas, with sustainability.
4th, because the real pipe in gas guide bend pipe with elbow has elbow, therefore, it is possible to effectively prevent rainwater by gas Body guide bend pipe directly carries out contacting the problem as Leachate site into junk-heap body with rubbish, reduces Leachate site yield, has Effect mitigates the pressure of leachate treatment facility, reduces landfill yard running cost.
Brief description of the drawings
Fig. 1 shows for the structure of the gas drainage device covered for household refuse landfill sites that the utility model is provided temporarily It is intended to.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art The utility model can be better understood from and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
The utility model provides a kind of gas drainage device covered temporarily for household refuse landfill sites, as shown in figure 1, The household refuse landfill sites include that junk-heap body layer 6 is 200mm-500mm by its top laying a layer thickness after shaping (Preferably 300mm)Clay layer 5, and interim cover layer 1 is laid in the top of the clay layer 5, and the interim cover layer 1 is used HDPE film, thickness is 1.0-1.5mm(Preferably 1.5mm)Constitute interim covering system.In above-mentioned interim covering system according to facing When overlay area area rationally plug gas drainage device, gas drainage device is specially gas guide bend pipe, and it includes one Two body formed parts, are respectively inserted in the straight floral tube 3 in clay layer 5 and junk-heap body 6, can use internal diameter for The HDPE floral tubes of 50-100mm, its outside parcel using non-woven geotextile 2 is protected, it is to avoid fine particle is blocked up in junk-heap body Plug straight floral tube 3.It is 0.5-1m that the non-woven geotextile 2 encloses the height that sets in the outside of straight floral tube 3, enclose the width that sets as 0.2m.The grammes per square metre of the non-woven geotextile 2 is 200-600g/m2.Also include being integrally formed, being in the top of straight floral tube 3 The real pipe 4 with elbow of the top of clay layer 5, it uses internal diameter to be managed in fact for the HDPE of 50-100mm, by bend design Prevent rainwater from being entered into junk-heap body 6 by HDPE reality pipes and form Leachate site.The whole height of the real pipe 4 with elbow It is 0.2m, wherein the height of elbow part is 0.1m.The straight floral tube 3 is equal with the internal diameter of the real pipe 4 with elbow.It is described After gas guide bend pipe installation, in addition it is also necessary to the interim covering that the real pipe 4 with elbow is used in interim covering system Sealed between film 1, encapsulation process can be carried out using extruding welding, and weldquality is ensured using related detecting method.
