Ukuphucula umgangatho wemveliso yendawo kunye nokhuseleko ngexesha lokusetyenziswa, kungekuphela nje ukuba umgangatho weemveliso ezifakelweyo ulawulwa ngokungqongqo, kodwa nokusetyenziswa kwezibalo kufuneka zilawulwe ngokungqongqo. Indlela efanelekileyo yokusetyenziswa ayinakuqinisekisa kuphela ukhuseleko lokwakha ukuya kuthi ga kubungakanani kodwa kwaye ikwanceda ukwahlula ubomi be-Fasttener. Ezi ziqwengana ze-staint ezintlanu zensimbi yokusebenzisa amanyathelo okhuseleko kufuneka zilandelwe ngokungqongqo kwaye zibanjwe yiyunithi yokwakha:
1. Isicwangciso sokwakha kufuneka silungiswe ngaphambi kokwenziwa kombhobho wentsimbi yentsimbi yentsimbi, kwaye isicwangciso esingqongqo esingqongqo nesikhangile esingqongqo kwaye kufuneka senziwe. Ukuba isicwangciso asikho kakuhle, ezinye iziganeko zoKhuseleko zangaphambili zinokwenzeka ngexesha lokwakha.
2. Imibhobho yentsimbi kunye neendlela zentsimbi ezisetyenziswa kwi-Fictener yohlobo lwe-Fittener kufuneka isampulu kwaye ivavanywe ngaphambi kokusetyenziswa. Umgangatho kunye nembonakalo yemibhobho yentsimbi kunye neendlela zentsimbi kufuneka zifakwe isampulu ukukhangela ukuba ngaba umgangatho kunye nembonakalo yemibhobho yentsimbi kunye ne-fastteners ziyayifezekisa imigangatho. Ubuninzi besampulu efanelekileyo iya kwenziwa ngemigaqo efanelekileyo kwaye iya kwenziwa ngendlela ethile. Uvavanyo lweSampulu, olungachazwanga, okanye olungafaneleki alusetyenziswanga.
I-3. Umgangatho wokubonakala olwenziweyo kufuneka uhlolwe rhoqo. Umphezulu wezinto ezikhethiweyo kufuneka uphathwe ngokuthintela i-rust Kwisikali se-oxide, indawo ye-oxidation yeamanye amalungu akufuneki abe ngaphezulu kwe-150mm2; Izilongikazi ezinamachaphaza ane-rocks, ishedform okanye i-slipping kwi-bolts zithintelwe ukuba zisetyenziswe, ukunqanda ukungalungisi nokwakha kunye neengozi ezibangelwa zizinto ezizezona zalo.
4. Umphezulu ofanelekileyo we-fasttener kwaye umbhobho wentsimbi kufuneka ubekwe ngokungqongqo ukuqinisekisa ukuba iipropathi ze-Anti-i-anti Inxalenye eshukumayo kufuneka ikwazi ukujikeleza ngokuguquguqukayo, kunye nomsantsa phakathi kwemiphezulu emibini ejikelezayo yendawo ejikelezileyo ye-Roustan ejikelezileyo kufuneka ingaphantsi kwe-1mm.
5. Ngokuphathelele amandla okutya, umthwalo wokwakha kwicandelo lokusebenzela kufuneka uhlangabezane neemfuno zoyilo, kwaye akufuneki ukuba igcwaliswe kakhulu, kwaye kufuneka ithwale ubunzima obuthile. Isicaka masingaqhagamshelwa kwinkxaso yeFowuni, kwaye unyango oluthile kufuneka lwenziwe xa liqhagamshelwe ukuqinisekisa ukuphathwa kwengqiqo.
IXESHA LOKUQALA: UNv-12 ukuya ku-520
