Umshini wokwenza i-keel yensimbi ekhanyayo iyimishini yobungcweti esetshenziselwa ukucubungula izinhlobo ezahlukahlukene kanye nokucaciswa kwemikhiqizo ye-keel edingekayo ezakhiweni zensimbi ezingasindi. Le mishini isebenzisa ubuchwepheshe obuthuthukisiwe bokulawula okuzenzakalelayo, inezici zokunemba okuphezulu nokusebenza kahle okuphezulu, futhi ingakhiqiza ngokushesha futhi ngokuzinzile imikhiqizo ye-keel ehlangabezana nezidingo zamakhasimende. Umshini wokwenza i-keel yensimbi elula kulula ukusebenza, ungalungiswa ngokushesha ngokuvumelana nezidingo zamakhasimende, futhi unesiqinisekiso sokusebenza esithembekile, futhi ungasetshenziswa kabanzi emkhakheni wokwakha kanye nobunjiniyela bezakhiwo. Ngokusebenzisa imishini yokwenza insimbi elula yensimbi, amakhasimende angathola ikhwalithi ephezulu, eyenziwe ngezifiso imikhiqizo yensimbi ekhanyayo ukuze ahlangabezane nezidingo zamaphrojekthi ahlukene wokwakha nobunjiniyela.
