Brief description
Fig. 1 is the structural representation of landfill yard tube-through type gas level collection system described in the utility model.
Fig. 2 is metal net shaped box schematic internal view described in the utility model.
Fig. 3 is horizontal discharge schematic cross-section described in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, the landfill yard tube-through type gas level collection system that the utility model provides, comprising: a plurality of gravel
Passage 100, a plurality of french drain, metal net shaped box 300 and horizontal collecting pipe 400.
Wherein, in landfill yard during processing gas, in the gravel passage of the internal angularly disposed a lot of of refuse landfill
100；
A plurality of french drain, it is horizontally set on refuse landfill top, and connects with gravel passage 100, and french drain can arrange and cut
Face area is tentatively set to 700mm × 700mm (size with landfill depth of field can expand), and every french drain is of length no more than
120m, every layer of horizontal interval is between 15m to 50m.
Metal net shaped box 300, it is rectangle, is arranged on inside french drain, and net box (3) section is 400mm × 400mm's
Square sectional, elongated metal net box (3) surrounding section all close including above.
As Figure 2-3, horizontal collecting pipe 400, it has rectangular through-holes, and wears and be connected on metal net shaped box 300 central authorities
Position, from the hdpe flexible pipe of a diameter of 40mm, every sono-explorer is 5m, and the connection between Guan Yuguan can be using a kind of saw
Dentation can stretch antidamping joint 410 come to reduce differential settlement to pipeline endanger, in order to prevent perforated pipe occur gravel block up
Plug, can adopt rectangular perforation means, and punching rate should improve on the premise of ensureing Management of Pipeline Mechanical Equipment intensity as far as possible.Hdpe flexible pipe is attached
Closely fill out the thick gravel layer 430 of 100mm, gravel diameter 15mm, to prevent rubbish blocking hole
As a kind of preferably, interface material can adopt hdpe material, the length of interface and the diameter can be with landfill
The increasing of buried depth and expand, single horizontal discharge central authorities bottom arrange strip tee section be spill anti-uneven sink
The cushion block 420 of fall, the spacing of cushion block 420 is 5m.
When there is differential settlement when the internal rubbish of landfill yard becomes thoroughly decomposed, horizontal guide pipeline 400 can with french drain together
Bend, and be in same direction, now so first zigzag can stretch the joint 410 of antidamping can with level
Guide pipeline 400 direction is distorted in rotation, and the stretching in power or compression direction and flexible, and horizontal wireway occurs
The strip cushion block 420 of the anti-differential settlement of road 400 bottom can have been redistributed on single wireway power and make list with moment
The deformation of the horizontal wireway of root is reduced.
Metal frame net box 300 outer wrap a layer thickness is the hdpe film 310 of 1.5mm-2.5mm thickness, plays anti-
Ooze, stop steam above little liquid pearl and each layer of french drain in landfill gas from entering horizontal discharge, prevent the impact collection that results in blockage
Gas yield, can protect netted can 300 again.
The surrounding of hdpe film 310 can arrange the sand bed 320 of one layer of waterproof and breathable of parcel protecting hdpe film 310.Prevent
Hdpe film 310 is punctured, and each level course discharge 400 is connected with vertical gravel layer 430, can be with mould at gravel layer 430
Paste is processed.
When there is differential settlement when the internal rubbish of landfill yard becomes thoroughly decomposed, horizontal guide pipeline 400 can with french drain together
Bend, and be in same direction, now so first zigzag can stretch the joint 410 of antidamping can with level
Collecting pipe 400 direction is distorted in rotation, and the stretching in power or compression direction and flexible, and horizontal wireway occurs
Strip cushion block 420 to the anti-differential settlement of 400 bottoms can redistribute on single wireway power and moment makes list
The deformation of the horizontal guide pipeline of root 400 is reduced.In addition in draining Anti-seepage air-permeable part, to be assisted using thin Anti-seepage air-permeable sand bed 320
Hdpe film 310 is helped to complete, with good protection hdpe film 310, such hdpe film 310 is just not for Anti-seepage air-permeable sand bed 320
Can easily be pierced through by the internal hard thing of landfill yard.And in terms of another, because there being waterproof and breathable sand bed 320, can
With the thickness of suitable minimizing gravel protective layer 430, construction is economical.
And the discharge french drain in the superiors lays compacted lift 500 with preventing from leaking above gas, in compacted lift 500
Top arranges drainage blanket 600 to avoid the impact to landfill gas for the rainwater above landfill yard, and compacted lift 500 and drainage blanket
600 can preferably control the temperature within landfill yard again, control and adjust humidity it is considered that humid control is in 60%-
70% becoming thoroughly decomposed than conveniently rubbish.One layer of Landfill covering layer 700 is set in drainage blanket 600 again, can plant above it
Some vegetation, this three layers temperature above landfill yard so that within landfill yard of covering, humidity be in one constant
Value.And so that the pernicious gas within landfill yard is not easy to evaporate and enters not going to inside with the rainwater on landfill yard surface.?
Later stage can be planted vegetation and be afforested to improve the environment of landfill yard surrounding.
The gas gathering system pipe 800 that vertically connects of each horizontal collecting pipe 400 the top horizontal bore discharge is converged
Always, gas in system is derived.
The utility model has the utility model and has simple structure, convenient installation, and uniformly, power transmission is bright for each member stress
Really, stable system, is easy to process, and effectively improves anti-uneven ability and has improved the ability of impervious discharge opeing and carry
The high efficiency of gas collection.The advantages of when reply differential settlement between each Guan Yuguan occurs, impact is less.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
It is easily achieved other modification, therefore under the universal being limited without departing substantially from claim and equivalency range, this reality
It is not limited to specific details with new and shown here as the legend with description.
