I-1. Ukunyuka okuphezulu kwesca
Ukunyuka okuphezulu kwescaffivel kunokubangela i-20m. Kwimeko yokungafuneki, ukwakhiwa ngokubanzi kuqala kwinqanaba lesine nelesihlanu; Xa idlula i-20m, ayinakuphakanyiswa ngaphezulu, kuba i-cantilever iphezulu kakhulu, iya kuthi ibize ngakumbi.
2. Izilumkiso zokuthintela i-stafFolfing ye-Scacheffed ngolu hlobo lulandelayo:
I-1. Ingavumelekanga ukuya kwi-Drill kunye ne-Drill Holes kwintsimbi yentsimbi, kunye ne-welding phakathi kwentsimbi yetayile kunye ne-anchorid bar bar bar kufuneka ifezekise imigaqo efanelekileyo kunye neemfuno zomgangatho. Kufuneka kuqatshelwe ukuba ubude be-Steel nganye yentsimbi kufuneka ifike kwi-30mm, kwaye ubuncwane be-welding Seam kufuneka bube yi-8mm.
2. Ukuvulwa kwengubo ye-angle elungileyo eyenzakalisa i-rossbar enkulu enqamlezileyo kufuneka ijonge phezulu, kwaye ukuvulwa kwebala le-butt kufuneka kujonge phezulu okanye ngaphakathi; Ukongeza, amalungu e-butt yebar enkulu enqamlezileyo kufuneka ilungiselelwe ngendlela ecekeceke, ibekwe kumhlathi omnye, kwaye kufuneka ikuphephe ukuyibeka embindini wesithuba, kwaye umgama othe tyaba phakathi kwe-500mm.
3. Intonga yokudibanisa kufuneka idityaniswe ngokuthe tyaba okanye ityekele ezantsi ukuya kwisiphelo sesicaka, kwaye ayivumelekanga ukunxibelelana nesiphelo esinye ses scapfold kwindawo ephezulu.
4. Ngexesha lokwakhiwa, kuya kwenziwa ukwakhiwa, kuya kwenziwa kwakhona ngokungqinelana nezibonelelo ezifanelekileyo zendawo yokwakha kunye nokulandelelana okuthe nkqo, kunye nokuphambuka ngokuthe nkqo kwePole nkqo kwaye ukuphambuka ngokuthe nkqo kwePole ethe tyaba kuya kulawulwa kakuhle. Ukongeza, xa ufaka iibhloko, ingqalelo kufuneka ihlawulwe ngokufanelekileyo iqinisa iingcambu emva kokuba iphindwe kabini ukuqinisekisa ukuba unxibelelwano oludibeneyo luhlangabezana neemfuno.
5. Ngexesha lokuhombisa umhombiso, kuphela umsebenzi owenziwayo owenziwayo. Ukongeza, xa uchitha i-scaffings, ngaphambi kokuba ususe udonga lokugqibela lwentonga yokuqhagamshela, ukuphosa kufuneka kubekiwe kuqala kwaye emva koko i-Wall yodonga isuswe.
