Shenzhen waa mid ka mid ah magaalooyinka badan ee Shiinaha ee ku socda wadada casriyeynta degdega ah.Ma aha si lama filaan ah, kobaca warshadaha iyo deggenaanshiyaha ee magaalada ayaa abuuray caqabado badan oo tayada deegaanka ah.Hong Hua Ling Landfill waa qayb gaar ah oo ka mid ah horumarinta Shenzhen, waayo qashin-qubka ayaa tusaale u ah kaliya caqabadaha hab-dhaqankii qashinka ee hore ee magaalada laakiin sida mustaqbalkeeda loo ilaalinayo.
Hong Hua Ling waxa ay shaqaynaysay muddo sanado ah, iyada oo aqbashay noocyo badan oo ka mid ah durdurrada qashinka, oo ay ku jiraan noocyada qashinka loo arko kuwo xasaasi ah (tusaale, qashinka caafimaadka).Si loo saxo habkan hore, balaadhinta casriga ah ayaa lagu baaqay.
Naqshadaynta balaarineed ee 140,000m2 ee xiga ayaa awood u siisay goobta in ay maamusho ku dhawaad kala badh qashin qubka Shenzhen's Longgang, oo ay ku jirto qaadashada 1,600 tan oo qashin ah maalin kasta.
BALAADINTA DHULKA EE SHENZHEN
Nidaamka dahaarka ee la balaariyay ayaa markii hore lagu nashqadeeyay saldhig laba-gees ah, laakiin falanqaynta juqraafigu waxay ogaatay in lakabka dhoobada ah ee jira 2.3m - 5.9m oo leh qulqulo hoose uu u dhaqmi karo sidii caqabad labaad.Laydhka aasaasiga ah, in kastoo, loo baahan yahay inuu noqdo xal geosynthetic tayo sare leh.
HDPE geomembrane ayaa la cayimay, oo leh 1.5mm iyo 2.0mm dhumucdiisuna waxay tahay geomembrane oo loo doortay isticmaalka aagag kala duwan.Injineerada mashruucu waxay adeegsadeen tilmaamo badan marka ay samaynayaan sifada agabkooda iyo go'aamada dhumucda, oo ay ku jiraan CJ/T-234 Tilmaamaha Cufnaanta Sare ee Polyethylene (HDPE) ee Qashin-qubka iyo Heerka GB16889-2008 ee Xakamaynta Wasakhda ee Goobta Qashin-qubka ee qashinka Adag ee Dawladda Hoose.
HDPE-ga geomembrane ayaa laga faa'iidaystay dhammaan goobta ballaadhinta qashin-qubka.
Saldhigga, xayndaab siman ayaa la doortay halka geomembrane oogada qaabaysan ee la qurxiyey loo doortay aagagga jiilalka ah ee ka sarreeya geomembrane dusha la isku dubariday ama lagu buufiyay qaabaysan.
Faa'iidooyinka waxqabadka is-khilaafsan interface waa ia ay sabab u tahay qaab-dhismeedka iyo isku midka ah ee dusha xuubka.Isticmaalka geomembrane HDPE ayaa sidoo kale bixisay faa'iidooyinka hawlgalka iyo dhismaha ee kooxda injineernimada naqshadeynta ay rabeen: iska caabin sare oo diiqad, Heerka qulqulka dhalaalka sare si loo suurtageliyo waxqabadka alxanka xooggan, iska caabbinta kiimikada heer sare ah, iwm.
Shabaqyada dareeraha ayaa loo isticmaalay sidii lakabka ogaanshaha daadinta iyo sidii lakabka dheecaan ka hooseeya wadarta guud.Lakabyadan dheecaanku waxay sidoo kale leeyihiin laba hawlood oo ay ka ilaalinayaan geomembrane HDPE ee waxyeellada dalool ee iman karta.Ilaalinta dheeraadka ah waxaa bixiyay lakab geotextile adag oo ku yaal inta u dhaxaysa geomembrane HDPE iyo hooska dhoobada qaro weyn.
CAQABADAHA GAAR AH
Hawlaha dhismaha ee Hong Hua Ling Landfill waxaa lagu fuliyay jadwal aad u adag, sababtoo ah cadaadiska aagga si degdeg ah u koraya si uu u yeesho balaadhinta weyn ee qashin-qubka sida ugu dhakhsaha badan.
Shaqooyinka bilowga ah waxaa lagu sameeyay 50,000m2 geomembrane markii hore, ka dib 250,000m2 ee soo haray ee geomembrane loo baahan yahay ayaa la isticmaalay mar dambe.
Tani waxay abuurtay dhibic taxaddar ah halkaas oo soo-saareyaasha HDPE ee kala duwan ay u baahan yihiin in la isku dhufto.Heshiska heerka qulqulka dhalaalka ayaa ahaa mid muhiim ah, waxaana falanqaynta lagu ogaaday in MFR-yada agabku ay la mid yihiin kuwa ku filan si looga hortago in baalalku kala go'aan.Intaa waxaa dheer, tijaabooyinka cadaadiska hawada ayaa lagu sameeyay kala-goysyada guddiga si loo xaqiijiyo cidhiidhiga alxanka.
Meel kale oo qandaraaslaha iyo lataliyuhu ay ahayd inay fiiro gaar ah u yeeshaan waxay tixgeliyeen habka dhismaha ee loo isticmaalo jiirada qaloocan.Miisaaniyadda waa la xaddiday, taas oo macnaheedu yahay in si adag loo xakameeyo agabka.Kooxdu waxay ogaadeen in samaynta jiirada oo leh baalal barbar socda jiirada ay ka badbaadin karto alaabta, sababtoo ah qaar ka mid ah duubabka la gooyay ayaa loo isticmaali karaa qalooca marka loo eego baalasha lagu jaray balac gaaban oo yar oo qashinka ah.Dhinaca hoose ee habkani waxa uu ahaa in ay u baahday alxanka goobta weyn ee alaabta, laakiin alxankahan dhamaantood waxa kormeeray oo ay xaqiijiyeen kooxda dhismaha iyo CQA si loo hubiyo tayada alxanka.
Balaadhinta qashinka Hong Hua Ling ayaa bixin doonta wadarta 2,080,000 oo tan oo qashinka lagu kaydiyo.
