Kwizicelo zokwakha kunye nezoshishino, ukukhethwa kwezinto eziphathekayo kunokuchaphazela kakhulu ukusebenza kunye nexesha elide leprojekthi. Phakathi kwezinto ezininzi ezikhoyo, umbhobho wentsimbi odityanisiweyo, ngakumbi umbhobho wentsimbi wekhabhoni ovundiweyo, ugqame njengolona khetho luphezulu ngenxa yokuqina kunye namandla. Kule posi yebhlog, siza kuphonononga izizathu ezisemva kolu khetho kwaye siqaqambise iingenelo zokusebenzisa umbhobho wentsimbi oshukumayo.
Esinye sezizathu eziphambili zokuba kutheni i-weldableumbhobho wentsimbiidume kakhulu kuzo zonke iindidi zamashishini kukuqina kwayo okuphezulu. I-spiral welding process inomoya kwaye idibanisa umcu oqhubekayo wentsimbi kwimilo ye-cylindrical, iqinisekisa ubukhulu obufanayo kuwo wonke umbhobho. Oku kufana kubalulekile kuba kunciphisa amanqaku abuthathaka anokubangela ukuba umbhobho ungaphumeleli phantsi koxinzelelo okanye uxinzelelo. Imveliso yokugqibela yomelele kwaye yomelele, kwaye inokumelana neemeko ezirhabaxa zokusingqongileyo, iyenze ilungele ioli negesi, ukuthuthwa kwamanzi, kunye nezicelo zenkxaso yesakhiwo.
Ukongeza, itekhnoloji ye-welding ye-spiral inokuvelisa imibhobho emikhulu yedayamitha kuneendlela zokuwelda zemveli ezithe ngqo. Oku kunenzuzo ngokukodwa kwiiprojekthi ezifuna umthamo omkhulu wombhobho, njengoko kunciphisa inani lamalungu afunekayo, ngaloo ndlela kuncitshiswe ukuvuza. Amalungu amancinci athetha umngcipheko ophantsi wokungaphumeleli, okuyinzuzo ebalulekileyo kwizicelo zoxinzelelo oluphezulu.
Imibhobho yentsimbi edityanisiweyo ayinamandla kwaye ihlala ihlala njalo, kodwa inezinto ezininzi. Zingasetyenziswa kwizicelo ezahlukeneyo, ukusuka kwiiprojekthi zeziseko ezingundoqo ukuya kwiinkqubo zokuvelisa. Zidityaniswe ngokulula kwamanye amacandelo, zivumela ukudityaniswa komthungo kwiinkqubo esele zikhona, zizenza zibe lolona khetho lukhethwayo lweenjineli kunye neekontraka.
Inkampani ekhokelayo kwimveliso yomgangatho ophezulu we-spiralumbhobho wentsimbi edityanisiweyoinerekhodi enomtsalane. Ngempahla epheleleyo ye-RMB 680 yezigidi kunye nabasebenzi abazinikeleyo abangama-680, inkampani ibe yinkokeli yoshishino. Umthamo wayo wemveliso nawo uyamangalisa, kunye nemveliso yonyaka yeetoni ezingama-400,000 zemibhobho yentsimbi ejikelezayo kunye nexabiso lemveliso ye-RMB 1.8 yezigidigidi. Imveliso enkulu kangaka ayibonisi nje ukuzibophelela kwenkampani kumgangatho, kodwa ikwabonisa amandla ayo okuhlangabezana neemfuno zeeprojekthi ezinkulu.
Inkampani igxile kulawulo lomgangatho kuyo yonke inkqubo yemveliso, iqinisekisa ukuba umbhobho ngamnye udibana nemigangatho engqongqo yoshishino. Oku kuzibophelela ekugqweseni kuyayihlula kukhuphiswano kwaye konyusa ukuthembeka kwemveliso. Abathengi banokuqiniseka ukuba ngokukhetha imibhobho yensimbi edibeneyo yomenzi, batyala imali kwimveliso eya kuhlala.
Lilonke, umbhobho wentsimbi odityanisiweyo, ngakumbi umbhobho wentsimbi wekhabhoni ovundiweyo, uyathandwa ngenxa yokuqina kwawo okungenakuthelekiswa nanto, ukomelela kunye nokuguquguquka. Inkqubo entsha ye-welding ye-spiral iqinisekisa ubukhulu obufanayo kwaye inciphisa umngcipheko wokungaphumeleli, okwenza le mibhobho ibe yinto efanelekileyo kwizicelo ezahlukeneyo. Ngabavelisi abahloniphekileyo abakhokelayo, abathengi banokuba nentembelo ekukhethweni kwezinto eziphathekayo kuyo nayiphi na iprojekthi. Xa ukuqina kunye namandla kubalulekile, umbhobho wensimbi odibeneyo lukhetho olucacileyo.
