Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, should be original including being successively covered in from top to bottom based on the pollution barrier structure that seepage control system constructs
Leachate site lead layer 7, film up-protective layer 6, impervious barrier 5, film lower protective layer 4, compacting soil padding 3 and pressure on film in waste layer 1
Real waste layer 2.Be compacted waste layer 2 be to be compacted to the top of conventional garbage layer 1, make its surface formed one layer of relative density compared with
The compactness of big compacting waste layer 2, compacting waste layer 2 is greater than 0.9.It is compacted soil padding 3 to be compacted using clay, is compacted soil padding
3 thickness is greater than 1m, and the compactness of compacting soil padding 3 is greater than 0.93.It is compacted soil padding 3 and compacting waste layer 2 is used as antiseepage system
The ground of system can effectively improve the strength and stability of ground.It is disposed with gas guide pipeline in compacting soil padding 3, gas is led
The outer surface of comb line is enclosed with speed row dragon, and the landfill gas in waste layer 1 can be delivered to gas collection by gas guide pipeline
Device avoids gas localized clusters bring security risk and pollution environment.
Film lower protective layer 4 is 600g/m2Non-woven geotextile, likewise, film up-protective layer 6 also be 600g/m2Nonwoven soil
Work cloth.Non-woven geotextile has the advantages that reinforcement protection effect, tensile strength are high, ageing-resistant and corrosion resistant, by impervious barrier 5
Upper and lower part film up-protective layer 6 and film lower protective layer 4 is respectively set, can be to anti-when differential settlement occurs for rubbish heap
Infiltration layer 5 plays a very good protection.
To lower part waste layer 1, impervious barrier 5 is HDPE film for diffusion and rain leakage of the impervious barrier 5 for blocking pollutant,
HDPE film with a thickness of 2.0mm.HDPE film has incomparable anti-seepage effect, while HDPE antiseepage film also has high ductibility
And stability, excellent elasticity and deformability can successfully manage rubbish heap and differential settlement bring problem on deformation occur.
When the gradient is greater than 5%, double matte HDPE films are can be used in impervious barrier 5, effectively junk-heap body are avoided to slide.Pass through impervious barrier
5 pairs of top rainwater obstruct, and effectively avoid the problem that rainwater infiltration brings further pollution, original waste layer 1 due to
The supplement not polluted newly, original pollution can be solved over time, to achieve the purpose that pollution control.
Leachate site lead layer 7 is cobble lead layer on film, and the thickness of cobble lead layer is greater than 30mm, ovum in cobble lead layer
The partial size of stone is 30mm-60mm.So that Leachate site lead layer 7 on film is contained only 1-2 low spot by flattening refuse landfill, passes through
Leachate site pipeline is set in low spot, Leachate site is sent to water processing establishment, can effectively avoid Leachate site accumulation and bring junk-heap body
The risk of sliding.
As shown in Fig. 2, the utility model also provides a kind of pollution blocking method based on seepage control system building, it is based on antiseepage
System building pollution blocking method the following steps are included:
Step a1 is compacted the top of conventional garbage layer 1, so that its surface is formed one and is laminated real waste layer 2；
Step a2 arranges gas guide pipeline on the top of compacting waste layer 2, and is laid with compacting soil padding 3；
Step a3 is laid with film lower protective layer 4 on the top of compacting soil padding 3；
Step a4 is laid with impervious barrier 5 on the top of film lower protective layer 4；
Step a5 is laid with film up-protective layer 6 on the top of impervious barrier 5；
Step a6 is laid with Leachate site lead layer 7 on film on the top of film up-protective layer 6.
Further, following steps are also executed while executing step a6: leveling refuse landfill makes Leachate site on film
Lead layer 7 contains only 1-2 low spot, and the quantity of low spot is determined with specific reference to the area of refuse landfill, then is arranged in low spot and is seeped
Liquid pipe line is dripped, is sent the Leachate site in place to water processing establishment using Leachate site pipeline, Leachate site accumulation is can effectively avoid and brings
The risk of junk-heap body sliding.
Junk-heap body is divided into two solely by the pollution blocking method based on seepage control system building of the utility model
Vertical aqueous vapor guide unit, original aqueous vapor guide unit are similar to the landfill yard to have closed in the later period runs, are substantially carried out dirt
Dye control and processing；Newly-built aqueous vapor guide unit can effectively realize the pollution barriers function of landfill yard, and the later period can be by sanitary landfills
Field operations specification runs well.
Although being above described in detail with generality explanation and specific embodiment to the utility model,
On the basis of the utility model, it can be modified or is improved, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
