Shenzhen nderimwe remaguta mazhinji eChina ari munzira inokurumidza yemazuva ano.Kwete zvisingatarisirwi, kukurumidza kweguta maindasitiri uye kukura kwekugara kwakagadzira akawanda emhando yemamiriro ekunze matambudziko.Iyo Hong Hua Ling Landfill chikamu chakasarudzika chekusimudzira kweShenzhen, nekuti iyo marara inongoratidzira kwete chete matambudziko eguta rekare maitiro emarara asi kuti ramangwana raro rinodzivirirwa sei.
Hong Hua Ling akashanda kwemakore, achigamuchira marudzi akawanda emarara, kusanganisira marudzi emarara anoonekwa seanonyanya kuoma (semuenzaniso, marara ekurapa).Kururamisa iyi nzira yekare, kuwedzera kwemazuva ano kwakadikanwa.
Iyo yakazotevera 140,000m2 dhizaini yekuwedzera marara yakagonesa saiti kubata ingangoita hafu yekuraswa kwemarara munzvimbo yeShenzhen's Longgang, kusanganisira kubvuma 1,600 matani emarara zuva nezuva.
KUWEDZERA KWERASHA MUSHENZHEN
Iyo yakawedzera dhizaini yenzvimbo yakatanga kugadzirwa ine mitsara ine mitsara miviri, asi ongororo ye geological yakawana kuti ivhu riripo re2.3m - 5.9m rine kuderera kwekupinda rinogona kuita sechipiri chipingamupinyi.Iyo yekutanga liner, zvakadaro, yaida kuve yemhando yepamusoro geosynthetic mhinduro.
HDPE geomembrane yakatsanangurwa, ine 1.5mm uye 2.0mm gobvu geomembranes yakasarudzwa kuti ishandiswe munzvimbo dzakasiyana.Iwo mainjiniya epurojekiti akashandisa akawanda nhungamiro mukuita kwavo hunhu uye ukobvu sarudzo, kusanganisira iyo CJ/T-234 Nhungamiro yePamusoro Density Polyethylene (HDPE) yeLandfills uye iyo GB16889-2008 Standard Yekusvibisa Kudzora paLandfill Saiti yeMasisita Solid Waste.
HDPE geomembranes yakashandiswa munzvimbo yese yekuwedzera marara.
Pachigadziko, liner yakatsetseka yakasarudzwa nepo yakamisikidzwa, yakarongeka yepasi geomembrane yakasarudzirwa nzvimbo dzakatenuka pamusoro pe-co-extruded kana kupfapfaidzwa-pamusoro peyakarongeka geomembrane.
Zvakanakira zve interface friction performance ia nekuda kwechimiro uye homogeneousness ye membrane pamusoro.Kushandiswa kweiyi HDPE geomembrane kwakapawo mabhenefiti ekushanda nekuvaka aidiwa nechikwata cheinjiniya chekugadzira: kushushikana kwakanyanya-kupwanya kuramba, yakakwira Melt Flow Rate yekugonesa kushanda kwakasimba kwewelding, yakanakisa makemikari kuramba, nezvimwe.
Drainage netting yakashandiswa senzvimbo yekuona pakubuda uye sedhiri remvura pazasi peaggregate.Aya madhiraini madhiri zvakare ane basa rehuviri rekuchengetedza iyo HDPE geomembrane kubva kune inogona kukanganisa puncture.Kuwedzera dziviriro kwakapihwa neiyo yakasimba geotextile layer iri pakati peHDPE geomembrane uye gobvu revhu revhu.
MAZHINJI AKASIYANA
Mabasa ekuvaka paHong Hua Ling Landfill akaitwa panguva yakaoma kwazvo, nekuda kwekumanikidzwa kwenzvimbo iri kukura nekukurumidza kuti ive nekuwedzera kukuru kwekurasira kushanda nekukurumidza.
Mabasa ekutanga akaitwa ne50,000m2 yegeomembrane kekutanga, kozoita 250,000m2 yakasara yegeomembranes inodiwa yakashandiswa gare gare.
Izvi zvakagadzira yambiro apo mugadziri akasiyana HDPE maumbirwo aifanira kubatanidzwa pamwechete.Chibvumirano muMelt Flow Rate chaive chakakosha, uye ongororo yakawana maMFR emidziyo yakafanana zvakakwana kudzivirira mapaneru kuparara.Uyezve, bvunzo dzekumanikidza kwemhepo dzakaitwa pamajoini epaneru kuratidza kusimba kweweld.
Imwe nzvimbo iyo mugadziri wekondirakiti nenyanzvi vaifanira kunyatsoteerera yakatarisa nzira yekuvaka yakashandiswa nemateru akakombama.Mari yacho yakaganhurirwa, izvo zvaireva kudzora kwakasimba kwezvinhu.Chikwata ichi chakaona kuti kugadzira materu ane mapaneru anoenderana nemateru anogona kuchengetedza zvinhu, sezvo mamwe emapumburu akachekwa aigona kushandiswa pamukombero wakapihwa mapaneru akachekwa muhupamhi hupfupi uye kusaraswa kushoma pakucheka.Kuipa kweiyi nzira yaive yekuti yaida simbi yakakura yeweld yemidziyo, asi mawelds aya ese akatariswa nekuongororwa nevakavaka uye timu yeCQA kuti ive nechokwadi chemhando yeweld.
Iyo Hong Hua Ling Landfill yekuwedzera ichapa huwandu hwakazara hwe2,080,000 matani ekuchengetedza marara.
