Imigangatho yemizi-mveliso kunye neenkcukacha zeetyathanga zothutho kunye neetyathanga zokuqhawula ziqinisekisa ukhuseleko, ukuthembeka, kunye nokuthotyelwa kweemfuno zomthetho.
Imigangatho ephambili
- EN 12195-3: Lo mgangatho uchaza iimfuno zemixokelelwane yokubopha esetyenziselwa ukukhusela imithwalo kwiindlela zokuhamba. Ugubungela uyilo, ukusebenza, kunye novavanyo lwemixokelelwane, kubandakanya umthwalo wayo wokuphuka, amandla okubopha, kunye neemfuno zokumakisha.
- AS/NZS 4344: Lo mgangatho unika izikhokelo zokuthintela umthwalo kwizithuthi zendlela, kuquka nokusetyenziswa kweentambo zokubophelela. Ucacisa umthwalo omncinci wokuphuka kunye nomthamo wokubophelela kwiintambo ezisetyenziswa ekuqiniseni imithwalo.
- ISO 9001:2015: Nangona ingaphelelanga kwiindlela zokuthutha, le migangatho yolawulo lomgangatho iqinisekisa ukuba abavelisi bagcina imigangatho ephezulu kwimveliso nasekunikezelweni kweenkonzo.
- ISO 45001:2018: Lo mgangatho ugxile kwiinkqubo zolawulo lwempilo nokhuseleko emsebenzini, ukuqinisekisa iimeko zokusebenza ezikhuselekileyo ekuvelisweni nasekuphathweni kweetyathanga zothutho.
Iinkcukacha
- Umthwalo Wokuqhawula: Umthwalo omncinci wokuqhawula wetsheyini, olona gunya likhulu itsheyini enokumelana nalo ngaphambi kokuba iqhekeke.
- Umthamo wokuLashing: Umthamo osebenzayo wokuthwala umthwalo wetsheyini, ngesiqhelo isiqingatha somthwalo omncinci wokuqhekeka.
- Ukuphawula: Iitsheyini maziphawulwe ngokucacileyo ngomthamo wazo wokuzibopha, umthwalo wokuqhawula, kunye nolunye ulwazi olufanelekileyo.
- Ukuhlolwa: Kufuneka kuhlolwe rhoqo iitsheyini ukuze kubonwe ukuba zigugile, zinde, kwaye zonakele. Iitsheyini akufuneki zisetyenziswe ukuba zingaphezulu kwe-3%.
- Izixhobo Zokuxinanisa: Iitsheyini kufuneka zixhotyiswe ngezixhobo zokuxinanisa ezifana neenkqubo ze-ratchet okanye ze-turnbuckle ukuze zigcine uxinzelelo olufanelekileyo ngexesha lokuthuthwa.
Le migangatho kunye neenkcukacha zinceda ekuqinisekiseni ukuba iintambo zothutho kunye neentambo zokubopha zisetyenziswa ngokukhuselekileyo nangokufanelekileyo ukukhusela imithwalo ngexesha lokuthuthwa.
Ngokulandela la manyathelo, ungakhusela imithwalo kwiilori zeelori ngempumelelo, uqinisekise ukuba uthutho lukhuselekile kwaye lusebenza kakuhle.
1. Ukulungiselela:
- Hlola iiTsheyini: Ngaphambi kokuba uyisebenzise, hlola iitsheyini ukuze ubone ukuba azinazo naziphi na iimpawu zokuguguleka, ukunwebeka, okanye umonakalo. Iitsheyini akufuneki zisetyenziswe ukuba ziguguleke kakhulu (ngaphezulu kwe-3%).
- Jonga umthwalo: Qinisekisa ukuba umthwalo ulungelelaniswe kakuhle kwaye ulungelelaniswe ngaphakathi kwilori
2. Ukuthintela:
- Izakhiwo zokuBloka eziZinzileyo: Sebenzisa izakhiwo zokuBloka ezizinzileyo ezifana nee-headboards, ii-bulkheads, kunye nee-stakes ukuthintela umthwalo ukuba ungahambi phambili okanye ubuye umva.
- Iingxowa zeDunnage: Sebenzisa iingxowa zeDunnage okanye iiwedges ukugcwalisa izithuba kunye nokubonelela ngenkxaso eyongezelelweyo.
3. Ukubethelwa ngemivumbo:
- Ukubethela i-Top-Over: Ncamathisela ii-lashings kwi-engile ye-30-60° kwibhedi yeplatifomu. Le ndlela iyasebenza ekuthinteleni ukujika nokutyibilika.
- Ukuqhawula iLoop Lashing: Sebenzisa isibini see-loop lashings kwicandelo ngalinye ukuthintela ukuhamba ecaleni. Kwiyunithi zemithwalo emide, sebenzisa ubuncinane isibini see-loop ukuthintela ukujijeka.
- Ukulesa ngokuthe Tye: Ncamathisela iilesa kwi-engile ye-30-60° kwibhedi yeqonga. Le ndlela ifanelekile ekuqiniseni imithwalo ngobude nangokwamacala.
- Ukubethela entwasahlobo: Sebenzisa ukubethela entwasahlobo ukuthintela intshukumo phambili okanye ngasemva. I-engile phakathi kokubethela kunye nebhedi yeplatifomu kufuneka ibe yi-45° ubuninzi.
4. Uxinzelelo:
- Iinkqubo zeRatchet okanye zeTurnbuckle: Sebenzisa izixhobo ezifanelekileyo zokuqinisa ukuqina kwetyathanga. Qinisekisa ukuba isixhobo sokuqinisa ukuqina siyakwazi ukuthintela ukukhululeka ngexesha lokuthuthwa.
- Ukususwa kwe-Post Tensioning: Nciphisa i-post tensioning clearance ukuya kwi-150 mm ukuze uphephe iintshukumo zomthwalo ngenxa yokuzinza okanye ukungcangcazela.
5. Ukuthobela imithetho:
- Imigangatho: Qinisekisa ukuba iitsheyini ziyahlangabezana nemigangatho efanelekileyo efana ne-EN 12195-3 yomthamo wokubethela kunye namandla okukhusela.
- Izikhokelo zoKhuseleko loMthwalo: Landela izikhokelo zamazwe ngamazwe malunga nokhuseleko lomthwalo kwiindlela zothutho ukuqinisekisa ukhuseleko kunye nokuthobela imithetho.
