Noma ubani ohlelayoizakhiwo zensimbieduze nogu uthola ngokushesha ukuthi imithetho ihlukile. Indawo ibuyela emuva kakhulu, futhi isakhiwo kufanele sikulungele.
Lelo gebe phakathi komklamo ojwayelekile wangaphakathi nedolobha kanye nowasogwini yilapho amaphrojekthi avame ukuba nenkinga khona - ngokuvamile ngemva kokuba isabelomali sesivele simisiwe.
Kungani Izimo Zasogwini Zishintsha Isibalo Sesakhiwo
Isici esisheshayo umthwalo womoya. Izindawo zasogwini naseziqhingini zichayeke emimoyeni evamile futhi azinawo umkhoselo wemvelo. Ngaphezu kwalokho, izindawo ezishisayo nezishisayo zengeza izehlakalo zokucindezela kwesiphepho ezingabanjwa ngamatafula okulayisha ajwayelekile ngamandla afanayo.
Siqede i-iphrojekthi yefektrieSolomon Islands okubonisa lokhu ngokucacile. Indawo yokwakha yayingamamitha angu-60 × 30 × 7.5 — amamitha-skwele angu-1,800 wendawo yephansi. Ngokwezindinganiso eziningi, leso yisakhiwo sezimboni esincane. Kodwa isakhiwo sensimbi sodwa sasidinga amathani angu-200 ezinto zokwakha. Lokho kusebenza cishe kumakhilogremu angu-111 ensimbi ngemitha-skwele yendawo yephansi.
Ukubeka leso sibalo esimweni: ngisho nangemva kokubala uhlobo lwesakhiwo kanye nokungabikho kwemithwalo ye-crane noma imishini esindayo elengayo, i-111 kg/m² isalokhu iyisibalo esiphezulu ngokuphawulekayo. Indawo yomoya ogwini yenza umsebenzi omningi lapha.
Ngakho-ke yini ekhulisa lelo nani? Iziqhingi zaseSolomon zisesifundeni esinomoya ovunguzayo ophezulu. Izidingo zomthwalo womoya wendawo zacindezela uhlaka oluyinhloko ngokujulile nangokusindayo. Isikhala sezinsika saqiniswa. Ukwakheka kwezinsimbi zokubopha kwanda. Izingxenye ze-purlin zophahla zanda. Wonke amalungu esakhiwo asukuma ukuze athwale imithwalo isakhiwo esisendaweni evikelekile yangaphakathi nezwe esingeke sibhekane nayo.
Ngaphezu kwalokho, ukuvikelwa kokugqwala kwengeze olunye ungqimba lwemininingwane. Umoya wasogwini uthwala ama-aerosol kasawoti asheshisa ukubola kwensimbi. Ngenxa yalokho, izindinganiso zokwelashwa kwendawo zadlula izinhlelo ezijwayelekile ze-primer. I-hot-dip galvanizing kumalungu esibili, izembozo zezinga eliphezulu kumafreyimu ayinhloko, kanye nemininingwane yokuxhumeka evaliwe konke kwengezwe kububanzi bezinto ezibonakalayo.
Akukho kulokhu okungajwayelekile endaweni. Kodwa kusho ukuthi izilinganiso zezindleko ezivela kwamanye amaphrojekthi — ikakhulukazi angaphakathi — azihumushi ngendlela ethembekile.
Lokhu Kusho Ukuthini Ngokuhlela Iphrojekthi Yakho
Umphumela ongokoqobo ulula. Izakhiwo zensimbi ezindaweni ezisogwini zidinga ukwakheka kwesakhiwo okuqondene nendawo ethile, hhayi amathempulethi ajwayelekile alungisiwe. Umehluko ubonakala ku-tonnage, kanti i-tonnage iyabonakala kwisabelomali.
Lokhu kubaluleke kakhulu ngesikhathi sokusebenza kwasekuqaleni. Amaphrojekthi amaningi abeka isabelomali sawo sensimbi ngokusekelwe endaweni yephansi yodwa, esebenzisa izinga elijwayelekile ngemitha yesikwele. Ezindaweni ezisogwini naseziqhingini, leyo ndlela iveza ukunganakwa njalo. Iphrojekthi yaseSolomon Islands iyindawo enhle yokubhekisela: isakhiwo esifanayo esingamamitha-skwele angu-1,800 endaweni enomoya ophansi ngaphakathi ezweni singasebenzisa amathani angu-60 kuya kwangu-70 ensimbi. Umklamo wasogwini wawudinga okungaphezu kokuphindwe kathathu kwalokho.
Ngale kwesakhiwo esiyinhloko, izakhiwo zensimbi zasogwini nazo zidinga ukunakwa kakhulu ekuchazeni imininingwane yokuxhumeka, ukufinyelela kokugcinwa, kanye ne-geometry yokukhipha amanzi. Amanzi amile eduze kokuxhumeka kwensimbi asheshisa ukugqwala. Ngenxa yalokho, ukuthambeka kophahla, ubukhulu bemisele, kanye nokuvalwa kokungena konke kunesisindo esikhulu ezinqumweni zokuklama.
Uma iphrojekthi isheshe ibangele lezi zici, indlela eya kwisabelomali esinembile kanye nesakhiwo esithembekile izoba bushelelezi. Uma indawo yakho ingaphakathi kwamakhilomitha angama-20 ogwini — noma esiqhingini — kufanelekile ukubuyekeza isigaba sendawo yomoya kanye nesigaba sokugqwala ngaphambi kokuphothula noma yikuphi ukuqagela kwesakhiwo.
Ukwabelana ngendawo yesayithi lakho kanye nobukhulu besakhiwo obuyisisekelo ngokuvamile kwanele ukuphawula lapho indlela ejwayelekile ingadinga ukulungiswa khona.
