Ukwakhiwa kwemibhobho yindlela yokwakhiwa kwemibhobho ephantsi komhlaba ephuhliswe emva kolwakhiwo lwekhaka.Ayifuni ukugrunjwa kweeleya zomphezulu, kwaye inokudlula kwiindlela, oololiwe, imilambo, izakhiwo ezingaphezulu, izakhiwo ezingaphantsi komhlaba, kunye nemibhobho eyahlukeneyo engaphantsi komhlaba.

Ukwakhiwa kwemibhobho kusebenzisa i-thrust ye-cylinder yokukrazula kunye negumbi lokudlulisa phakathi kwemibhobho ukutyhala umbhobho wesixhobo okanye i-header yendlela ukusuka ekusebenzeni kakuhle kumaleko womhlaba ukuya kwindawo eyamkelekileyo.Ngelo xesha, umbhobho ngokukhawuleza emva kombhobho wesixhobo okanye umatshini wokubhoboza wangcwatywa phakathi kwamaqula amabini, ukuze kuqatshelwe indlela yokwakha yokubeka imibhobho engaphantsi komhlaba ngaphandle kokumba.
