Shenhai e fakamoʻoni fakaʻauha
ʻOku fakataumuʻa ʻa e tunnels ʻuhila ʻi lalofonua ke centralize ha kakai kehekehe pipelines ki ha faʻunga ʻe taha, mo ha feituʻu ʻoku tanaki atu ki he kau ngaue monomono ke nau ʻunu holo. ʻOku ʻikai ngata pe ʻi hono fakahaofi ʻe he fokotuʻutuʻu ko ʻeni ʻa e tafaʻaki mo e feituʻu ʻoku ʻataa ka ʻoku ne toe fakafaingofuaʻi foki hono tokangaʻi mo hono tokangaʻi ʻo e pipelines. Ko e fakaʻekonomika, fakasosiale, mo e ngaahi lelei ʻo e ʻatakai ʻo e tunnels pehee ʻoku mahuʻinga. TATAKI e ngaahi maama ʻo e fakamoʻoni fakaʻauha ʻoku ne feau e ngaahi fie maʻu ʻa e tunnels ko ʻeni, kau ngaue ke nau vakaiʻi mo tauhi ʻa e faʻunga ʻo e tanolo, ʻa ia ʻoku ʻaonga ki hono tokangaʻi mo fakalahi e ngaahi ngaue.
ʻOku kehe hono langa ʻo e tunnels ʻuhila ʻi lalofonua mei hono langa. Koeʻuhi ko e fakangatangata ʻo e ʻatakai makehe, hange ko e ʻea hauhau mo e siʻisiʻi ʻo e maama fakanatula, ʻOku mahuʻinga ʻa e maama falalaʻanga. ʻOku mahuʻinga tatau pe ʻa e maama fakataimi hono naunau ʻi he ngaahi tuʻunga ko ʻeni. Meʻangaue fakaʻuhila angamaheni ʻo e feituʻu langa, hange ko e ngaahi foʻi ʻuhila pe taki tiupi, fakatupu ha ngaahi faingataʻa lahi:
1. ʻOku faʻa fakaʻaongaʻi ʻa e pipelines fakataimi lolotonga hono fola ki he ngaahi fie maʻu fakaʻuhila fakataimi lolotonga hono langa, taki ki he ngaahi fakatuʻutāmaki ki he malú.
2. ʻOku faʻa incurs ʻe hono fokotuʻu ʻo e mama hono naunau mo e pipelines ʻo fakaʻaongaʻi ʻa e tiupi pe ngaahi foʻi ʻuhila incurs tohi lesoni maʻolunga mo e fakamole fakaʻekonomika.
3. ʻOku fakahehema ʻa e mama hono naunau ke maumau koeʻuhi ko e ngaahi ʻekitiviti ʻa e tangata pea ʻoku faingataʻa ke toe fakaʻaongaʻi koeʻuhi ko e fefonongaʻaki mo e ngaahi meʻa breakage.
4. ʻI lalofonua tunnels, ʻe lava ʻe he ʻea hauhau maʻolunga ʻo fakatupu ha maama tukufakaholo hono naunau ke corrode, uesia honau fotunga mo e ngaue. ʻE lava ke iku ʻa e Condensation ki he circuits nounou mo e toutou ʻi ai ha ngaahi meʻa.
5. ʻOku faʻa fakaiku ʻa e mamaʻo ʻi he ngaahi ngaue langa ʻi he tanolo ki hono fakaʻaongaʻi ʻo e ngaahi uaea motuʻa pe ngaahi uaea ʻalaminiume ke fakasiʻisiʻi ʻa e fakamole. ʻE lava ke iku ʻeni ki he fakafepaki lahi ʻi he polokalama ʻuhila, fakatupu ha voltage feʻunga ʻi he ngataʻanga ʻo e seini. ʻOku fakaiku ʻeni ki he poipoila ʻa e mama mo e maumau ʻo e naunau, uesia e ngaahi ʻekitivitī langa angamahení.
Ko ia, ʻOku mahuʻinga ha founga ʻaonga mo fakahangatonu ki he tunnels ʻi lalofonua.
Naʻe tataki ʻe he fili ʻa e ngaahi maʻuʻanga maama ʻo e Siteiti, ʻa ia ʻoku tauʻataina mei he fusion mo e ngaahi fehalaaki embrittlement, mo e ko ha ʻavalisi lifespan fuʻu lahi 50,000 houa ʻe, ʻomi ha founga taʻetotongi ki hono tokangaʻi. ʻOku lolotonga hoko ʻa e ngaahi maʻuʻanga maama lelei taha, tokonaki ʻo e 50-70% paʻanga ʻoku fakahuu ʻi hono fakafehoanaki ki he ngaahi maʻuʻanga tokoni tuku. ʻOku nau aʻusia ʻa e malohi tatau ʻi he malohi ʻo e Output, fakataha mo e ngaahi tuʻunga moʻui ʻo e ʻatakai. ʻOku tuʻu maʻu ʻa e hono naunau, Tolonga, pea ʻe lava ke ne ʻomi scientifically ʻa e mama Layout mo e ngingila.
Ko ia, ʻa e aʻu mai ʻa e ngaahi maama ʻo e tanolo lea haohaoa ki he ngaahi meʻa ʻo e ʻea hauhau mo e corrosiveness maʻolunga ʻi lalofonua tunnels, ʻomi ha maama lelei.
