Kwizixhobo zangaphandle kunye neeprojekthi zokwakha, ukuqina kwezikrufu kuchaphazela ngokuthe ngqo uzinzo kunye nokhuseleko lwesakhiwo siphela. Izikrufu zentsimbi eziqhelekileyo zichaphazeleka lula kukufuma kunye ne-oxidation, nto leyo ebangela ukugqwala kunye nokukhululeka, ngelixa izikrufu zentsimbi engagqwaliyo ziye zaba lukhetho olufanelekileyo kwizicelo zangaphandle nezokwakha ngenxa yokumelana kwazo okuhle nokugqwala.

Kwizixhobo zanamhlanje zoomatshini kunye neenkqubo zokufaka imibhobho, ii-gaskets kunye nee-spring washers zincinci kodwa zidlala indima ebalulekileyo. Azinakunciphisa kuphela ukukhwankqiswa nomsindo ngokufanelekileyo, kodwa zikwathintela ukuvuza kolwelo okanye igesi, ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwenkqubo. Eli nqaku liza kuhlola nzulu indlela ezi ndawo zincinci zingabonakaliyo kodwa ziyimfuneko ezidlala ngayo indima enkulu.

Kwiminyaka yakutshanje, i-United States isebenzise uthotho lwemigaqo-nkqubo yerhafu yentsimbi ejolise ekukhuseleni imboni yentsimbi yasekhaya kunye nokugcina ukhuseleko lwesizwe. Nangona kunjalo, le migaqo-nkqubo ayibanga nefuthe elikhulu kuqoqosho lwasekhaya lwase-United States kuphela, kodwa ikwabe nefuthe elikhulu kwikhonkco lokubonelela ngempahla kwihlabathi liphela. Eli nqaku liza kuhlola imvelaphi, ukuphunyezwa kunye nefuthe elithile lomgaqo-nkqubo werhafu yentsimbi wase-US kwikhonkco lokubonelela ngempahla kwihlabathi liphela.

Kwimveliso yanamhlanje yemizi-mveliso nakubomi bemihla ngemihla, izikrufu zincinci kodwa zidlala indima ebalulekileyo. Izikrufu zentsimbi engagqwaliyo ziye zaba lukhetho lokuqala kwiimfuno zokufakelwa kwimizi-mveliso eyahlukeneyo ngenxa yokumelana kwazo nokugqwala okugqwesileyo, amandla aphezulu kunye nobomi benkonzo ende. Nokuba kukwakhiwa, ukwenziwa kweemoto, izixhobo ze-elektroniki, okanye ukuhombisa ikhaya, izikrufu zentsimbi engagqwaliyo zinokubonelela ngezisombululo zoqhagamshelo ezizinzileyo nezithembekileyo ukuhlangabezana neemfuno ezingqongqo kwiimeko ezahlukeneyo.

Kwinjineli yolwakhiwo, ukukhethwa kwezibophelelo kuchaphazela ngokuthe ngqo uzinzo kunye nokhuseleko lwesakhiwo siphela. Ii-U-bolts kunye nee-lock nuts zizinto eziphambili zoqhagamshelo kwaye zisetyenziswa kakhulu kwiibhulorho, izakhiwo, izixhobo zoomatshini, kunye neenkqubo zemibhobho. Aziboneleli nje kuphela ngamandla okubopha aqinileyo, kodwa zikwathintela ngokufanelekileyo ukukhululeka kwaye ziqinisekisa ukusebenza okuthembekileyo ixesha elide. Eli nqaku liza kuhlalutya iingenelo zazo zokusetyenziswa nzulu ukukunceda ukhethe isisombululo sokubopha esifanelekileyo.

Kuyilo lwesakhiwo, ukusebenza kwe-seismic yenye yezinto ezibalulekileyo ukuqinisekisa ukhuseleko lwezakhiwo. Njengesixhobo esiqhelekileyo sokubambelela, i-U-bolt isetyenziswa kakhulu kuqhagamshelo lwe-seismic lwesakhiwo sesakhiwo ngenxa yokumelana kwayo nokuxinana okuhle kakhulu. Eli nqaku liza kuxoxa ngamanqaku oyilo, iingenelo kunye nezicwangciso zokusetyenziswa kwe-U-bolt kuqhagamshelo lwe-seismic.

Kwicandelo lokwenziwa kweemoto, ukukhethwa kweziqhoboshi zentsimbi engagqwaliyo kuchaphazela ngqo umgangatho wesithuthi. Njengezinto ezibalulekileyo zokudibanisa, amantongomane entsimbi engagqwaliyo kunye nezikrufu zokuzicofa zentsimbi engagqwaliyo ziba zizisombululo ezibalulekileyo zokuphucula ukuqina kunye nokubonakala kweemoto zanamhlanje ngenxa yokumelana kwazo nokugqwala, amandla aphezulu kunye neempawu zobuhle.
