Naka izindaba ezilandelayo lapho usetha amadivayisi wokuvikela okotshani:
1. Idivayisi enesisekelo kufanele yakhelwe ngokomkhawulo wokumelana nenhlabathi kanye nezimpawu zokuvuselela, njll. Ngemuva kokufaka, sebenzisa imitha yokumelana ukuze unqume ukuthi iyahlangabezana yini nezidingo.
2. Indawo yocingo enesisekelo kufanele ikhethwe endaweni okungeyona eyelula ukuthi abantu baye kuyo, ukugwema nokunciphisa ukulimala kwamandla ashubile futhi kuvimbele ucingo oluhlabayo ukuthi lulimele ngomshini. I-electrode ephansi kufanele igcinwe ibanga lamamitha amathathu noma ngaphezulu kwezinye izinsimbi noma izintambo.
3. Lapho impilo yenkonzo yedivaysi enesisekelo ingaphezu kwezinyanga eziyisithupha, akukuhle ukusebenzisa i-aluminium wire e-aluminium njenge-electrode enesisekelo noma ngocingo oluhlabayo ngaphansi komhlaba. Emhlabathini oqinile osolisayo, ama-electrodes asephepheni noma anezikhonkwane.
Ungayisetha kanjani idivaysi yokuvikela umbani:
1 Zifakiwe ezigxotsheni ezihlasela ezikwimithi emine yendlu, futhi ukuphakama akunakwehliswa okungaphansi kwemitha eyi-1, futhi zonke izigxobo ezivundlile kungqimba ephezulu kufanele zixhumeke ukuze zakhe inethiwekhi yokuvikela umbani. Lapho ufaka induku yombani kufreyimu yokuhamba mpo, i-maphakathi ne-pole ohlangothini olulodwa kufanele ixhunywe phezulu kungabi ngaphansi kwamamitha ayi-2 ngaphezulu phezulu. Ucingo oluhlabayo kufanele lubekwe emaphethelweni aphansi esigxobo, futhi ukugcotshwa komoya kufanele kube kusekelwe.
2. Ucingo olunesisekelo kufanele lwenziwe ngensimbi ngangokunokwenzeka. I-electrode ephansi eqondile ingaba yipayipi lensimbi elinobude obungu-1.5 kuya ku-2 amamitha-2, ububanzi obungamamitha angama-25 kuye kwangama-30 mm, kanye nodonga lwensimbi engaphansi kuka-2 mm noma ama-50 * 5 angle steel. I-electrode evundlile ingaba yinsimbi eyindilinga ngobude obungaphansi kwamamitha ayi-3 kanye nobubanzi be-8-14 mm noma insimbi eyisicaba enobukhulu obungaphansi kuka-4 mm nobubanzi be-25-40 mm. Futhi, amapayipi ensimbi, izinqwaba zensimbi, amapayipi e-drill, amapayipi amanzi, nezinhlaka zensimbi ezixhunywe ngokuthembekile emhlabathini zingasetshenziswa njenge-electrodes. I-electrode ephansi yengcwatshwa endaweni ephezulu kakhulu yomhlaba futhi ayikho ngaphansi kwama-50 cm ngaphansi komhlaba. Lapho engcwaba, ukugcwaliswa okusha kufanele kuhlazwe. Emhlabathini ovame ukufudumala eduze kwe-Steam Pipe noma i-chimney duct, ama-masonry akhiwe ngaphezulu kwezintambo zezinga eliphansi komhlaba ngeke angcwatshwe ku-coke slag noma isihlabathi, futhi ikakhulukazi izingqimba zenhlabathi ezomile.
I-3 Ukuze ugcine izinsimbi ezingezona ze-ferrous, insimbi eyindilinga enobubanzi obungaphansi kuka-8 mm noma insimbi eyisicaba enobukhulu obungaphansi kwe-4 mm ingasetshenziswa kwisisekelo sokuxhumana okuthembekile. Ukuxhumeka phakathi kocingo lomhlabathi kanye ne-electrode yomhlabathi kungcono ukusebenzisa i-welding, futhi ubude bendawo ye-welding kufanele bube ngaphezulu kwezikhathi ezi-6 ububanzi bomhlaba wensimbi noma ngaphezulu kwezikhathi ezi-2 ububanzi bensimbi ephansi. Uma kuxhunywe ngama-bolts, indawo yokuxhumana ngeke ibe ngaphansi kwezikhathi ezi-4 indawo ephambana nesigaba socingo esitelekile, bese ububanzi be-bolt ehlukanisayo ngeke ibe ngaphansi kwe-9 mm. Lokhu okungenhla yilokho esikuqoqe khona esimweni sethu somsebenzi. Kungaphezu kwalokho. Ngikholwa ukuthi ukuhlakanipha kwamaShayina akunamkhawulo.
