Njengomthetho, iprojekthi nganye igwetywa ngokusetyenziswa kwemibhobho yensimbi yesakhiwo ukusuka kumbono wobunjineli bokwakha kunye nolwakhiwo. Kukholelwa ukuba iprojekthi nganye kufuneka iqingqelwe imali phambi kokuba iprojekthi yakho iqale. Umbhobho wentsimbi uhlala uneendleko ezininzi xa uthelekisa nezinye izinto ezininzi zokwakha ngaphezulu kweminyaka engama-30. Ngaphandle koko, umbhobho wentsimbi wolwakhiwo uthathwa njengesixhobo sokwakha esisingqongileyo kushishino lokwakha. Nangona ixabiso lombhobho wentsimbi alizinzanga kangako kwimarike, oku kusengaphantsi ngokuthelekisa namaxabiso ekhonkrithi asele elungile kwangaxeshanye. Ngaphezu koko, into yokuba awufuni iingcali ezinezakhono eziphezulu ukufaka isakhiwo sakho sesinyithi kwindawo, ixabiso lofakelo lokwenene lisezantsi kakhulu.
Umbhobho wentsimbi owenziwe ngamachiza ngokuqhelekileyo uneendleko ezisengqiqweni ezisebenzayo kwimarike. Ngokungafaniyo nezinye izinto zentsimbi yesakhiwo, intsimbi ye-galvanized ilungele ngokukhawuleza ukusetyenziswa xa ihanjiswa. Akukho kulungiswa okongeziweyo komphezulu ofunekayo, akukho kuhlolwa kwexesha elide, ukupeyinta okongezelelweyo okanye iingubo ezifunekayo. Emva kokuba isakhiwo sihlanganiswe, iikontraka zinokuqalisa ngokukhawuleza inqanaba elilandelayo lokwakha ngaphandle kokukhathazeka malunga nezixhobo zentsimbi. Uvavanyo kunye nophononongo lubonise ukuba umndilili wobomi bentsimbi esetyenziswe njengesixhobo solwakhiwo ungaphaya kweminyaka engama-50 kwindawo yasemaphandleni kunye neminyaka engama-20 ukuya kwengama-25 nangaphezulu kwindawo egqithisileyo yasedolophini okanye eselunxwemeni. Kulo mba, iikontraka zinokuyisebenzisa ngokuzithemba le mveliso kwiprojekthi.
Umbhobho wentsimbi oxande lilungu elinye lamacandelo akhiweyo angenamngxuma aziiprofayili zetsimbi ezinecandelo letyhubhu yesikwere okanye uxande. Amacandelwana anomgongxo abuxande akhiwe kwaye adityaniswe ukusuka nokuba kushushu kuqengqeleka, kuqengqeleke kubanda, kufakwe igalvanized okanye intsimbi engatyiwayo. I-ASTM A500 yeyona nto ixhaphakileyo yentsimbi yecandelo lolwakhiwo olungenamngxuma kwimarike yombhobho wentsimbi yangoku kwihlabathi jikelele. Olu lubalulo lwenzelwe ukubanda okudityanisiweyo okudityanisiweyo kunye nokungenamthungo kwetyhubhu yentsimbi yekhabhoni kumjikelo, isikwere kunye neemilo ezixande. I-ASTM A501 ngomnye umgangatho wetyhubhu yentsimbi eyenziwe eshushu. Umbhobho wensimbi we-Rectangular unemisebenzi emininzi efana nezicelo zesakhiwo kwindawo yokuhlala, yorhwebo kunye nokwakhiwa kwezoshishino. Ngaphandle koko, njengoko iindawo ezisikwere ezisicaba zombhobho wentsimbi oxande unamandla okunciphisa ulwakhiwo, ngamanye amaxesha zikhethwa ngobuhle boyilo lwezakhiwo kwizakhiwo eziveziweyo. Namhlanje, imibhobho yentsimbi exande iye yaduma kakhulu kwiindlela ezininzi zokwakha kunye nezinye izixhobo kunye nosetyenziso lomatshini.
Thumela umyalezo wakho kuthi:
