Amathangi Ensimbi Aboshwe Ngamabhawudi Okugcina Amanzi: Umhlahlandlela Ophelele Wobunjiniyela, Idizayini, Nokusetshenziswa
Ekuhanjisweni kwamanzi kamasipala, ukuvikelwa komlilo ezimbonini, nasekwenziweni kwezolimo okukhulu, ukuqukethwe koketshezi ngokuthembekile kubalulekile. Amathangi ensimbi avamile ashiselwayo nezakhiwo zikakhonkithi ezithelwayo zivame ukubandakanya izikhathi ezinde zokwakha, ukubambezeleka ngenxa yesimo sezulu, nezindleko eziphezulu zabasebenzi.
Njengendlela ethuthukisiwe, amathangi amanzi ensimbi aboshwe ngamabhawudi asephenduke izinga lembonini lokugcina amanzi ngendlela ephumelelayo, ekhulayo, nehlala isikhathi eside. Akhiwe ngamaphaneli enziwe ngobuchwepheshe obunembile aboshwa ndawonye endaweni yokusetshenziswa, la masistimu ehlanganisa amandla amakhulu okwakheka nokuvumelana okungenakuqhathaniswa kokusetshenziswa.
1. Izinga Lokukhiqiza Nobunjiniyela Eliyisisekelo
Ukuze kuqinisekiswe ukusebenza kwesikhathi eside ngaphansi kwemithwalo enzima ye-hydrostatic, izingcindezi zokuzamazama komhlaba, nezimo ezinzima zemvelo, amathangi ensimbi aboshwe ngamabhawudi asezingeni eliphezulu akhiqizwa ngokuqinisekisa okungqongqo kwamazinga omhlaba wonke obunjiniyela:
● ANSI/AWWA D103-09: Izinga eliyisisekelo le-American Water Works Association elilawula ukuklanywa, ukukhiqizwa, nokucaciswa kwezinto zokwakha zamathangi ensimbi aboshwe ngamabhawudi afakwe ukugoqwa kwefekthri okokugcina amanzi.
● ISO 28765 / ISO 9001: Amazinga omhlaba wonke ekhwalithi aqinisekisa ukuhlolwa okuqinile kokumelana namakhemikhali, ukuqinisekiswa kobukhulu bongqimba lokugoqwa, nokulawulwa kwekhwalithi yokukhiqiza okunembile.
● Ukuqinisekiswa kwe-NSF/ANSI 61: Kuyimpoqo ezinhlelweni zamanzi okuphuza, okuqinisekisa ukuthi izinto zangaphakathi zokumboza kanye nezinto zokuvala azikhiphi ubuthi obungcolisayo emanzini okusetshenziswa ngabantu.
2. Ukuqhathanisa Okubanzi: Insimbi Ehlanganiswe Ngamabhawudi vs. Insimbi Eshiselwe kanye Namathangi Kakhonkolo
Lapho kuhlolwa izindleko zokwakha (CAPEX) kanye nezindleko zokusebenza zempilo yonke (OPEX), onjiniyela bakamasipala kanye nabathuthukisi bamaphrojekthi baqhathanisa ubuchwepheshe bokugcina ngokwezinkomba ezibalulekile zokusebenza:
Ipharamitha Yokuhlola | Amathangi Ensimbi Aboshiwe | Amathangi Ensimbi Ahlanganiswe Endaweni | Amathangi Kakhonkolo Aphekwe Endaweni |
Isivinini Sokufakwa | Ukuhlanganiswa okusheshayo ngamaphaneli amamojula; umsebenzi omncane | Kancane; kudinga umsebenzi omningi wokushisela endaweni kanye nokuhlolwa nge-X-ray | Kancane kakhulu; kudinga uhlaka, ukuthela, nokuvuthwa kakhonkrithi |
Ukuncika Esimweni Sezulu | Kuphansi; ukwenziwa ngaphambilini efektri kugwema ukubambezeleka kwesimo sezulu endaweni | Phezulu; ukushisela emkhakheni kuthinteka kakhulu yimvula, umoya, namakhaza | Phezulu; ukwelapheka kukakhonkolo kudinga umswakama nokushisa okulawulwayo |
Ukukhula Nokunwetshwa | Phezulu; umklamo wamamojula uvumela ukwengezwa kwamaphaneli kalula noma ukuthuthwa | Kunzima kakhulu; kudinga ukusika okuyinkimbinkimbi nokushisela kabusha | Akunakwenzeka; indawo engaguquki ehlala njalo |
Ubuqotho Bokumboza | Kufakwe efemini (i-Glass-Fused-to-Steel noma i-thermal epoxy) ngaphansi kokulawulwa kwekhwalithi okuqinile | Ukumboza okufakwa endaweni yokusebenza kungenwa amaphutha omuntu nokungcola kwemvelo | Ngokuvamile akumboziwe noma kupendwe, kuthambekele ekuqhekekeni nasekuchithakaleni |
Isikhathi Sokuphila Sokuklanywa | Iminyaka engu-30 kuya kwengu-50+ (ngokunakekelwa okufanele) | Iminyaka engu-30 kuya kwengu-40 | Iminyaka engu-50+ (ngokuya ngobuqotho bokusimama kukakhonkolo wesakhiwo) |
3. Izingxenye Eziyinhloko Zesakhiwo Zamathangi Aboshiwe Okugcina
Ithangi lamanzi eliboshiwe elisebenza kahle kakhulu lisebenza njengohlelo lobunjiniyela oluhlanganisiwe, olunembile, olunemikhakha emithathu eyinhloko:
● Izindonga Zethangi: Zakhiwe ngamashidi ensimbi anamandla aphezulu ahlanganiswe noma ngabe i-Glass-Fused-to-Steel (GFS) enamel yeglasi noma i-epoxy eminingi ehlanganisiwe ngokushisisa. Amaphaneli ayagqagana futhi avalwe kusetshenziswa ama-gasket akhethekile e-elastomeric kanye namabhawudi ensimbi anamandla aphezulu e-hot-dip galvanized noma e-stainless steel (Grade 8.8 noma 10.9) anamakhanda asabalalisa umthwalo.
● Izinhlelo Zophahla: Zitholakala ngezindlela ezahlukene ezihlanganisa ama-geodesic domes e-aluminium, uphahla lwe-aluminium alloy trough deck oluzisekelayo, kanye nezakhiwo zensimbi eziyisicaba ezenzelwe ukumelana nomthwalo omkhulu weqhwa nomoya kuyilapho zivimbela ukungcola kwebhayoloji noma ukukhula kwe-algae.
● Izisekelo Nokuxhumana Kwezisekelo: Kuboshwe ngokuphephile ngodonga lwekhonkrithi eziyingilizi noma amaringi esisekelo akhiwe ngobunjiniyela (BSR), okuqinisekisa ukusatshalaliswa komthwalo ngokulinganayo nokumelana namandla omoya okugoqayo nokuzamazama komhlaba.
Imibuzo Ejwayelekile (FAQ)
Umbuzo: Iyini impilo elindelekile yethangi lensimbi elihlanganiswe ngamabhawudi lokugcina amanzi?
Impendulo: Uma likhiqizwa ngokwezindinganiso ze-AWWA D103 futhi lifakwe izinto zokumboza ezithuthukisiwe zasefektri ezifana ne-Glass-Fused-to-Steel (GFS) noma i-epoxy enzima, amathangi ensimbi ahlanganiswe ngamabhawudi afinyelela kalula impilo yokusebenza yeminyaka engu-30 kuya kwengu-50 noma ngaphezulu ngokugcinwa okuncane okuvamile.
Umbuzo: Amathangi ensimbi ahlanganiswe ngamabhawudi awavimbela kanjani ukuvuza emajoyintini amaphaneli?
A: Ukuqinisekiswa kokuvala kufezwa ngokusebenzisa izinto ezikhethekile zobunjiniyela zokuvala (ezifana ne-polyurethane noma ama-silicone compounds) ezifakwe phakathi kwamapulangwe ensimbi agawulwe ngokunembile. Amabhulokhi anamandla okudonsa abopha amashidi ndawonye ngaphansi kwe-torque ebalwayo, okudala ukuvala okuqinile, okungangeni umoya nokungangeni uketshezi, okumelana nokonakala kwamakhemikhali.
Umbuzo: Ingabe amathangi ensimbi aboshwe ngamabhawudi angakwazi ukunwetshwa uma izidingo zomthamo wokugcina zikhula?
Impendulo: Yebo. Enye yezinzuzo eziyinhloko zokusebenza kwamathangi amamojula aboshwe ngamabhawudi ukukwazi ukunwetshwa. Ngenxa yokuthi isakhiwo sakhiwe ngamaphaneli aboshwe ngamabhawudi enziwe ngaphambilini, abaqhubi bezikhungo bangakwazi ukuvula amaringi aphezulu bafake amaphaneli engeziwe ukuze bandise ukuphakama kanye nomthamo wethangi njengoba isidingo sikhula, bagweme isidingo sokufaka into entsha ngokuphelele.
Umbuzo: Ingabe amathangi ensimbi aboshwe ngamabhawudi afaneleka ezindaweni ezinokuzamazama komhlaba kanye nezindawo ezinomoya onamandla?
A: Impela. Amathangi esimbi aboshwe ngendlela yesimanje akhiwa ngobunjiniyela obuqinile kusetshenziswa izinsiza zokuhlaziya ezinqala ze-finite element analysis (FEA) kanye namathuluzi okumodela ingcindezi ukuze kuhlangatshezwane namakhodi okwakha endawo, amazinga e-American Society of Civil Engineers (ASCE), kanye nezidingo ze-International Building Code (IBC) zokuzamazama komhlaba nomoya.
