Imigangatho yemizi-mveliso kunye neenkcukacha zemixokelelwane yezothutho kunye namatyathanga okuqhawula iqinisekisa ukhuseleko, ukuthembeka, kunye nokuthotyelwa kweemfuneko zolawulo.
ImiGangatho ePhambili
I-EN 12195-3: Lo mgangatho uchaza iimfuno zamatyathanga okubopha asetyenziselwa ukukhusela imithwalo kuthutho lwendlela. Ibandakanya uyilo, ukusebenza, kunye novavanyo lwamatyathanga, kubandakanywa umthwalo wabo wokuqhawuka, amandla okubamba, kunye neemfuno zokumakisha.
- AS/NZS 4344: Lo mgangatho ubonelela ngezikhokelo zothintelo lomthwalo kwiimoto zendlela, kubandakanywa nokusetyenziswa kweentambo zokuqhawula. Icacisa umthwalo omncinci wokuqhawula kunye nomthamo wokuqhawula amatyathanga asetyenziselwa ukukhusela imithwalo.
- I-ISO 9001: 2015: Nangona ingacaciswanga kwiintambo zokuthutha, lo mgangatho wokulawula umgangatho uqinisekisa ukuba abavelisi bagcina imigangatho ephezulu kwimveliso kunye nokunikezelwa kwenkonzo.
- ISO 45001: 2018: Lo mgangatho ugxile kwiinkqubo zolawulo lwezempilo kunye nokhuseleko emsebenzini, ukuqinisekisa iimeko ezikhuselekileyo zokusebenza kwimveliso kunye nokuphathwa kwamakhonkco othutho.
Iinkcukacha
- Ukuqhawula Umthwalo: Ubuncinci bomthwalo wokuqhawula umxokelelwane, owona mandla aphezulu anokumelana nawo phambi kokuqhawula.
- Lashing Capacity: Umthamo osebenzayo wokuthwala umthwalo wekhonkco, ngokuqhelekileyo isiqingatha somthwalo omncinci wokuqhawula.
- Ukumakishwa: Amatyathanga kufuneka aphawulwe ngokucacileyo ngomthamo wawo wokuqhwala, umthwalo wokuqhawuka, kunye nolunye ulwazi olufanelekileyo.
- Ukuhlolwa: Ukuhlolwa rhoqo kwamatyathanga okunxiba, ukunweba, kunye nomonakalo kuyadingeka. Amatyathanga akufuneki asetyenziswe ukuba angaphezulu kwe-3% ubude.
- Izixhobo zokuXhaphaza: Amatyathanga kufuneka axhotyiswe ngezixhobo zoxinzelelo ezifana ne-ratchet okanye iisistim ze-turnbuckle ukugcina uxinzelelo olufanelekileyo ngexesha lothutho.
Le migangatho kunye neenkcukacha zinceda ekuqinisekiseni ukuba iintambo zothutho kunye neentambo zokuqhawula zisetyenziswa ngokukhuselekileyo nangempumelelo ukukhusela imithwalo ngexesha lokuthutha.
Ngokulandela la manyathelo, unokukhusela ngokufanelekileyo imithwalo kwiilori zelori, uqinisekise uthutho olukhuselekileyo nolusebenzayo.
1. Ukulungiselela:
-Hlola amatyathanga: Phambi kokusetyenziswa, jonga amatyathanga ukuze ubone naziphi na iimpawu zokuguga, ubude, okanye umonakalo. Amatyathanga akufuneki asetyenziswe ukuba anxibe kakhulu (ngaphezu kwe-3% ubude).
- Hlola umthwalo: Qinisekisa ukuba umthwalo ulungelelaniswe ngokufanelekileyo kwaye ulungelelanise ngaphakathi kwilori
2. Ukuvala:
-Izakhiwo zokuThintela eziZinzileyo: Sebenzisa izakhiwo ezivaliweyo zokuthintela njengee-headboards, ii-bulkheads, kunye nezibonda zokuthintela umthwalo ukuba ungahambi phambili okanye ngasemva.
- Iingxowa zeDunnage: Sebenzisa iingxowa ze-dunnage okanye iiweji ukuze ugcwalise i-voids kunye nokubonelela ngenkxaso eyongezelelweyo.
3. Ukubetha:
- I-Top-Over Lashing: Qhoboshela imivimbo kwi-angle ye-30-60 ° kwibhedi yesikhulumi. Le ndlela iyasebenza ekuthinteleni ukuncama kunye nokutyibilika.
- UkuLashing kweLoop: Sebenzisa iperi yokuqhawula intambo kwicandelo ngalinye ukuthintela ukuhamba ecaleni. Kwiiyunithi zempahla ezinde, sebenzisa ubuncinane izibini ezimbini ukuthintela ukujijeka.
- Ukubetha ngokuthe tye: Qhoboshela imivimbo kwi-angle ye-30-60 ° kwibhedi yeqonga. Le ndlela ifanelekile ukukhusela imithwalo ngobude kunye nasecaleni.
- I-Spring Lashing: Sebenzisa imivimbo yasentwasahlobo ukuthintela ukuhamba phambili okanye ngasemva. I-angle phakathi kwe-lashing kunye nebhedi yesikhulumi kufuneka ibe ngubuninzi be-45 °.
4. Uxinzelelo:
-IiRatchet okanye ii-Turnbuckle Systems: Sebenzisa izixhobo ezifanelekileyo zokuxinana ukugcina ukuxinana kwekhonkco. Qinisekisa ukuba isixhobo esibambayo siyakwazi ukunqanda ukukhululeka ngexesha lothutho.
- UCwangciso lwe-Post Tensioning: Nciphisa i-post tension clearance ukuya kwi-150 mm ukunqanda ukushukuma komthwalo ngenxa yokuhla okanye ukungcangcazela.
5. Ukuthobela:
- Imigangatho: Ukuqinisekisa ukuba amatyathanga adibana nemigangatho efanelekileyo efana ne-EN 12195-3 yomthamo we-lashing kunye namandla obungqina.
- Izikhokelo zoKhuseleko lomthwalo: Landela izikhokelo zamazwe ngamazwe malunga nokhuseleko lomthwalo wothutho ezindleleni ukuqinisekisa ukhuseleko nokuthotyelwa.
