Shenzhen ni umwe mu mijyi myinshi y'Ubushinwa mu nzira yihuse igezweho.Ntabwo mu buryo butunguranye, iterambere ryihuse ryumujyi n’imiturire ryateje ibibazo byinshi by’ibidukikije.Imyanda ya Hong Hua Ling ni igice cyihariye cy’iterambere rya Shenzhen, kubera ko imyanda itagaragaza gusa imbogamizi z’imikorere y’imyanda yo muri uyu mujyi gusa ahubwo n’uburyo ejo hazaza harinzwe.
Hong Hua Ling imaze imyaka ikora, yemera ubwoko bwinshi bwimyanda, harimo nubwoko bwimyanda ifatwa nkibyoroshye (urugero, imyanda yubuvuzi).Kugira ngo ukosore ubu buryo bwa kera, kwaguka bigezweho byasabwe.
Igishushanyo mbonera cyo kwagura imyanda 140.000m2 cyafashije ikibanza gutunganya hafi kimwe cya kabiri cy’imyanda yose y’imyanda ya Shenzhen ya Longgang, harimo no kwakira toni 1,600 y’imyanda buri munsi.
KUGURISHA UBUTAKA I SHENZHEN
Sisitemu yagutse ya sisitemu yagutse yabanje gukorwa hifashishijwe ibice bibiri, ariko isesengura rya geologiya ryerekanye ko ibumba ririho rya 2,3m - 5.9m rifite ubushobozi buke rishobora kuba inzitizi ya kabiri.Umurongo wibanze, nubwo, wari ukeneye kuba igisubizo cyiza cya geosintetike.
HDPE geomembrane yarasobanuwe, hamwe na 1.5mm na 2.0mm z'uburebure bwa geomembrane zatoranijwe gukoreshwa muri zone zitandukanye.Ba injeniyeri b'umushinga bakoresheje umurongo ngenderwaho mu gufata ibyemezo biranga n'uburemere, harimo umurongo ngenderwaho wa CJ / T-234 kuri Polyethylene (HDPE) y’imyanda myinshi hamwe na GB16889-2008 yo kurwanya umwanda ku kibanza cy’imyanda ikorerwa mu mujyi.
HDPE geomembranes yakoreshejwe ahantu hose hagura imyanda.
Kuri base, hatoranijwe umurongo woroshye mugihe geomembrane yubuso, yubatswe hejuru yubuso bwahantu hahanamye hejuru yubuso bwakorewe hamwe cyangwa bwatewe hejuru ya geomembrane.
Ibyiza byimikorere yo guteranya imikorere ni ia bitewe nuburyo hamwe nubusumbane bwubuso bwa membrane.Ikoreshwa rya geomembrane ya HDPE ryanatanze inyungu zikorwa nubwubatsi itsinda ryabashakashatsi ryashakaga: kwihanganira guhangayikishwa cyane, umuvuduko mwinshi wa Melt Flow Rate kugirango ushobore gukora neza gusudira, kurwanya imiti myiza, nibindi.
Urushundura rwamazi rwakoreshwaga nkigice cyo gutemba kandi nkigice cyamazi munsi yigiteranyo.Izi miyoboro y'amazi nayo ifite imikorere ibiri yo kurinda HDPE geomembrane kwangirika kwangirika.Ubundi burinzi bwatanzwe na geotextile igoye iri hagati ya HDPE geomembrane na subgrade yibumba ryinshi.
INGORANE ZIDASANZWE
Imirimo yo kubaka ahitwa Hong Hua Ling Landfill yakozwe ku gihe cyagenwe cyane, bitewe n’igitutu cy’akarere gakura vuba kugira ngo imyanda nini yongere ikorwe vuba bishoboka.
Ibikorwa byambere byakorewe hamwe na 50.000m2 ya geomembrane mbere, hanyuma 250.000m2 isigaye ya geomembran isabwa yakoreshejwe nyuma.
Ibi byashizeho ingingo yo kwitondera aho uruganda rutandukanye rwa HDPE rukeneye gusudira hamwe.Amasezerano yo mu gipimo cya Melt Flow yari ingenzi, kandi isesengura ryasanze MFRs yibikoresho bisa bihagije kugirango ibuze gutandukana.Byongeye kandi, ibizamini byumuyaga byakorewe ku kibaho kugirango hamenyekane ubukana bwa weld.
Ahandi hantu rwiyemezamirimo numujyanama yagombaga kwitondera cyane harebwa uburyo bwubwubatsi bwakoreshejwe ahantu hahanamye.Ingengo yimari yarabujijwe, bivuze kugenzura neza ibikoresho.Iri tsinda ryasanze kubaka ahahanamye hifashishijwe imbaho zingana n’umusozi zishobora kuzigama ku bikoresho, kubera ko bimwe mu bitabo byaciwe byashoboraga gukoreshwa ku murongo bitewe n’uko imbaho zaciwe mu bugari bugufi hamwe n’imyanda mike ku gutema.Ikibi cyubu buryo ni uko byasabaga gusudira mu murima ibikoresho byinshi, ariko abo basudira bose bakurikiranwe kandi bagenzurwa nitsinda ryubwubatsi hamwe nitsinda rya CQA kugirango barebe neza ubudozi.
Kwagura imyanda ya Hong Hua Ling bizatanga ubushobozi bwa toni 2,080.000 zo kubika imyanda.
