ʻO Shenzhen kekahi o nā kūlanakauhale he nui o Kina ma ke ala wikiwiki.ʻAʻole i manaʻo ʻole ʻia, ʻo ka ulu wikiwiki ʻana o ka ʻoihana a me ka ulu ʻana o ke kūlanakauhale ua hoʻokumu i nā luʻina maikaʻi kaiapuni.He ʻāpana kū hoʻokahi ʻo Hong Hua Ling Landfill o ka hoʻomohala ʻana o Shenzhen, no ka mea, hōʻike ka ʻāina ʻaʻole wale i nā pilikia o nā hana ʻōpala i hala o ke kūlanakauhale akā pehea e pale ʻia ai kona wā e hiki mai ana.
Ua hana ʻo Hong Hua Ling no nā makahiki, e ʻae ana i nā ʻano kahawai ʻōpala, me nā ʻano ʻōpala i manaʻo ʻia ʻoi aku ka maʻalahi (e laʻa, nā ʻōpala lapaʻau).No ka hoʻoponopono ʻana i kēia ala kahiko, ua kāhea ʻia kahi hoʻonui hou.
ʻO ka hoʻolālā hoʻonui ʻāina he 140,000m2 ma hope mai ua hiki i ka pūnaewele ke lawelawe i ka hapalua o ka nui o ka hoʻolei ʻōpala o Shenzhen's Longgang area, me ka ʻae ʻana i 1,600 tons o ka ʻōpala i kēlā me kēia lā.
HOOLAHA AINA MA SHENZHEN
Ua hoʻolālā mua ʻia ka ʻōnaehana pale o ka wahi i hoʻonui ʻia me kahi kumu laina ʻelua, akā ua ʻike ʻia ka nānā ʻana i ke ʻano o ka pālolo o 2.3m – 5.9m me ka haʻahaʻa haʻahaʻa hiki ke hana ma ke ʻano he pale lua.ʻO ka liner mua, ʻoiai, pono e lilo i kahi hopena geosynthetic kiʻekiʻe.
Ua kuhikuhi ʻia ka geomembrane HDPE, me nā geomembrane mānoanoa 1.5mm a me 2.0mm i koho ʻia no ka hoʻohana ʻana i nā ʻāpana like ʻole.Ua hoʻohana nā ʻenekinia papahana i nā alakaʻi he nui i ka hana ʻana i kā lākou ʻano waiwai a me nā hoʻoholo mānoanoa, me ka CJ/T-234 Guideline on High Density Polyethylene (HDPE) for Landfills and the GB16889-2008 Standard for Pollution Control on the Landfill Site for Municipal Solid Waste.
Ua hoʻohana ʻia nā geomembranes HDPE ma ke kahua hoʻonui ʻāina.
Ma ke kumu, ua koho ʻia kahi liner maʻemaʻe ʻoiai ua koho ʻia kahi geomembrane ili i hoʻopaʻa ʻia no nā wahi sloped ma luna o ka geomembrane i hoʻokuʻu ʻia a i hoʻohu ʻia paha.
ʻO ka maikaʻi o ka hana friction interface ma muli o ke ʻano a me ka homogeneousness o ka ʻili membrane.ʻO ka hoʻohana ʻana i kēia HDPE geomembrane i hāʻawi pū i nā pono hana a me ke kūkulu ʻana i makemake ʻia e ka hui ʻenekinia hoʻolālā: ke kūpaʻa koʻikoʻi-kiʻekiʻe kiʻekiʻe, kahi kiʻekiʻe Melt Flow Rate e hiki ai i ka hana kuʻihao ikaika, ke kūpaʻa kemika maikaʻi loa, etc.
Ua hoʻohana ʻia ka ʻupena hoʻoheheʻe ma ke ʻano he papa ʻike leak a ma ke ʻano he papa hoʻoheheʻe ma lalo o ka aggregate.ʻO kēia mau papa hoʻoheheʻe wai he ʻelua hana no ka pale ʻana i ka geomembrane HDPE mai ka pōʻino o ka puncture.Hāʻawi ʻia ka pale ʻē aʻe e kahi papa geotextile ikaika e kū ana ma waena o ka geomembrane HDPE a me ka subgrade pālolo mānoanoa.
NA HOAO KUAI
Ua hoʻokō ʻia nā hana hana ma ka ʻāina ʻo Hong Hua Ling ma kahi papa hana paʻa loa, ma muli o ke kaomi ʻana i ka wahi e ulu wikiwiki ana e hoʻonui koke i ka hoʻonui ʻana i ka ʻāina.
Hana ʻia nā hana mua me 50,000m2 o ka geomembrane ma mua, a laila ua hoʻohana ʻia ke koena 250,000m2 o nā geomembrane i koi ʻia ma hope.
Ua hana kēia i kahi mākaʻikaʻi kahi e pono ai e hui pū ʻia nā ʻano hana HDPE like ʻole.He mea koʻikoʻi ka ʻaelike ma ka Melt Flow Rate, a ua ʻike ʻia ka like ʻana o nā MFR o nā mea i mea e pale ai i ka haki ʻana o nā panela.Eia kekahi, ua hana ʻia nā hoʻāʻo ʻana i ke ea ma nā hui panel e hōʻoia i ka paʻa o ka weld.
ʻO kahi ʻāpana ʻē aʻe e pono ai ka mea ʻaelike a me ke kākāʻōlelo e nānā nui i ke ʻano hana kūkulu i hoʻohana ʻia me nā pali curved.Kāohi ʻia ke kālā, ʻo ia ka manaʻo o ka mālama pono ʻana i nā mea.Ua ʻike ka hui ʻo ke kūkulu ʻana i ka pali me nā panela e pili ana i ka pali e hiki ke hoʻopakele i nā mea, no ka mea, hiki ke hoʻohana ʻia kekahi o nā ʻōwili i ʻoki ʻia ma ka ʻokiʻoki ʻoiai ua ʻoki ʻia nā panela i kahi ākea pōkole me ka liʻiliʻi o ka pau ʻana i ka ʻoki ʻana.ʻO ka ʻaoʻao haʻahaʻa o kēia ala, ʻo ia ka mea e koi ai i ka hoʻoheheʻe ʻia ʻana o nā mea, akā ua nānā ʻia kēia mau welds āpau a hōʻoia ʻia e ke kūkulu hale a me ka hui CQA e hōʻoia i ka maikaʻi o ka weld.
ʻO ka hoʻonui ʻia ʻana o ka ʻāina ʻo Hong Hua Ling e hāʻawi i ka nui o 2,080,000 tons o ka waiho ʻōpala.
