Ma nā papahana ʻenekinia huna—e like me nā tunnels, nā subway, a me nā alaloa pono honua—ʻaʻole lawelawe nā membrane pale wai ma ke ʻano he pale e hoʻokaʻawale i ka wai, akā, he "ʻāpana palupalu" hoʻi e komo ikaika ana i ka hoʻoponopono ʻana i ke kaumaha kūkulu. Ma ke ʻano he mea hana kūikawā ma ke kahua o geosynthetics, ua hoʻohana ʻo Shandong Hongyue Environmental Engineering Co., Ltd. (i kapa ʻia ma hope aku ʻo "Hongyue Environmental") i kona ʻike loea hohonu i nā membrane pale wai EVA (Ethylene-Vinyl Acetate Copolymer) e hana i kahi ʻōnaehana kūkulu ʻepekema, koʻikoʻi, a maʻamau. Ma o ʻekolu mau ʻano hana koʻikoʻi—"koho mea pololei, kuʻihao meticulous, a me ka hoʻopaʻa maʻamau"—hoʻohana piha ka hui i nā waiwai kūikawā o nā membrane EVA, me ka elongation kiʻekiʻe, ke kū'ē ʻana i ka mahana haʻahaʻa, a me ka ikaika haehae, no laila e hoʻokumu ana i kahi pale pale wai paʻa no nā ʻano papahana ʻenekinia like ʻole.
Ka Papa Hana ʻEkahi: Koho Kūpono i nā Mea a me ka Hoʻomākaukau ʻana i ka Substrate—Ke Kau nei i kahi Kumu Kūpono ʻole
Hoʻomaka kahi papahana pale wai kiʻekiʻe me ka kaohi pololei ʻana i nā mea. Hoʻohana nā membrane pale wai EVA a Hongyue Environmental i ka Ethylene-Vinyl Acetate Copolymer premium ma ke ʻano he mea maka mua; hōʻike lākou i ka elasticity e like me ka rubber, loaʻa iā lākou ka maʻalahi haʻahaʻa haʻahaʻa maikaʻi loa (mālama i ka pliability ʻoiai i nā kūlana anuanu mai -30°C a i -35°C), a haʻaheo i ka ikaika haehae kiʻekiʻe. Ma mua o ke kūkulu ʻana, pono e hoʻomākaukau pono ʻia ka substrate: pono e pālahalaha ka ʻili kumu, paʻa, a ʻaʻohe mea ʻino a i ʻole nā mea ʻoi, me ka hōʻoia ʻana ʻaʻohe wai kū, nā ʻōpala aila, a me ka lepo. Ma muli o ka nui o ka papahana a me kona wahi hana kikoʻī, hāʻawi ʻo Hongyue Environmental i nā membrane pale wai EVA i hana maʻamau ʻia i nā mānoanoa like ʻole - mai 0.5 mm a 2.5 mm - e hōʻoia i kahi kaulike kūpono ma waena o ka hana mea a me nā koi ʻenekinia.
KaʻAnuʻu Hana ʻElua: Nā Kaʻina Hana Kuʻi Paʻa—Ke Hoʻoholo nei i ke Ola o ka ʻŌnaehana Pale Wai
I ka wā o ke kūkulu ʻana ma ke kahua, ʻo ka hilinaʻi o ka membrane pale wai e hilinaʻi ana i 90% ma luna o ka maikaʻi o ka wili ʻana i ka ea wela. Ke koi nei ka hui loea o Hongyue Environmental e pono e haʻalele i ka manaʻo kuhihewa o ka mālama ʻana i ka wili ʻana ma ke ʻano he "hana uhi" wale nō; akā, pono e hoʻokau mua ʻia ma ke ʻano he hana koʻikoʻi. Pono e hoʻokō ʻia ke kūkulu ʻana me ka hoʻohana ʻana i nā mīkini wili kūikawā a i ʻole nā pū wili ea wela, me ka mahana o ka puka ea e kāohi pono ʻia i loko o ka pae o 320°C a 380°C. Ma mua o ka wili ʻana, pono e kāohi pono ʻia ka laulā overlap ma waena o nā pepa membrane e pili ana ma waena o 70 mm a me 100 mm, a pono e hoʻohana ʻia kahi palaki uea kila e wehe pono i kekahi lepo o ka ʻili a i ʻole nā papa oxidized mai nā wahi overlap. I ka wā o ke kaʻina hana wili, hoʻopili ʻia nā mahana kiʻekiʻe e hoʻoheheʻe i ka ʻili o ka mea EVA, a ukali ʻia e ke kaomi e hoʻohui i nā papa i loko o hoʻokahi ʻāpana paʻa. ʻO ka hōʻoia ma hope o ka wili ʻana e pili ana i kahi kaʻina hana nānā ʻekolu ʻanuʻu koʻikoʻi: ʻO ka mea mua, hana ʻia kahi nānā maka e hōʻoia i ka ʻike ʻia ʻana o ka humuhumu wili ma ke ʻano he ʻano like, moakaka, e like me ke aniani, me ka ʻole o nā pehu a i ʻole nā wrinkle. ʻO ka lua, hana ʻia kahi hoʻāʻo ʻili mechanical; ke hoʻopili ʻia ka ikaika tensile perpendicular i ka weld seam, pono e noho paʻa me ka ʻole o ka haki ʻana. ʻO ke kolu, inā pono, hana ʻia kahi hoʻāʻo inflation e hōʻoia i ka noho ʻana o kekahi pohō kaomi i loko o nā palena maʻamau i kuhikuhi ʻia.
KaʻAnuʻu Hana 3: Ka Hoʻopaʻa ʻEpekema a me ke Kau ʻana—Ke Hoʻopau nei i ka Pōpilikia o nā "Welds Wahaheʻe"
I ka wā o ke kūkulu ʻana ma nā wahi paʻakikī—e like me nā lei aliʻi tunnel—hiki i ke kaumaha ponoʻī o ka mea ke kumu maʻalahi iā ia e palupalu, e alakaʻi ana i nā "welds wahaheʻe" (nā humuhumu piha ʻole a nāwaliwali paha). Hoʻoikaika pono ʻo Hongyue Environmental Protection i ka pono o ka hoʻohana ʻana i kahi ʻano hana "zoned tensioning and segmented welding". Pili kēia i ka hoʻopaʻa mua ʻana i ka membrane waterproofing i ka substrate me ka hoʻohana ʻana i nā slings kūikawā i hoʻokaʻawale ʻia ma kahi o 300mm; a laila hoʻokuʻu ʻia ke kaumaha ma ka ʻāpana, me ka hana ʻana i ka welding i ka manawa like. Pale pono kēia ʻano hana i ka hanana ʻana o nā welds wahaheʻe i hoʻokumu ʻia e ka palupalu ʻana o ka mea ma lalo o kona kaumaha ponoʻī, no laila e hōʻoiaʻiʻo ana i kahi pilina paʻa a pili loa ma waena o ka membrane waterproofing a me ke ʻano kākoʻo mua. Eia kekahi, hōʻike nā membrane waterproofing EVA i ka launa pū ʻana me nā mea hoʻopili like ʻole; i ka wā o ka mālama kikoʻī ʻana i nā kihi, nā komo ʻana o ka paipu, a me nā wahi paʻakikī ʻē aʻe, hiki ke hoʻohana ʻia nā mea hoʻopili kūikawā e hoʻokō i ka sila wikiwiki a maikaʻi, no laila e hoʻonui hou aku i ka impermeability holoʻokoʻa o ka ʻōnaehana waterproofing.
Ma ka hoʻohana ʻana i kēia hoʻonohonoho o nā ʻano hana kūkulu maʻamau, hiki i nā membrane pale wai EVA a Shandong Hongyue Environmental Protection ke hōʻike piha i ko lākou mau pono koʻikoʻi—me ke kūpaʻa kūikawā i ka hydrolysis, ke kūpaʻa i ke komo ʻana o ke aʻa, a me ke ola lawelawe lōʻihi
