Ipayipi lokunweba elishisayo ipayipi lensimbi elicutshungulwa ngendlela ekhethekile ukunweba okushisayo ukusetshenziswa kwe-hydraulic noma izindlela zemishini ezikhuthaza ipayipi lensimbi elisuka odongeni lwensimbi eduze kobuchwepheshe bokucubungula ingcindezi yokuvula ngokunwebeka kwangaphandle.Izindlela zemishini kunezindlela zokusebenzisa amanzi amaningi, amadivaysi, amandla alula nangaphezulu emhlabeni ahamba phambili emhlabeni wonke onesikali esikhulu esishiselwe ukulawula inqubo yokwandisa amapayipi ashiselwe.

Indlela yokucubungula yepayipi yokwandisa okushisayo, ipayipi elincane lobubanzi obucubungula ipayipi elikhulu lobubanzi.Ipayipi lokunwebeka elishisayo eligoqelwe yinsimbi eshisayo kunaleyo encane.Kukhawulelwe kumashubhu ensimbi angenamthungo ajwayelekile anqunyelwe, ngokuya ngepayipi lokunwetshwa labathengi bokugcina elishisayo ukuze lizalwe, imodeli esezingeni elishisayo yokukhulisa ipayipi likhulu ngokuqhathaniswa, ngokuvamile elisekelwe ezidingweni zamakhasimende kanye nokukhiqiza, ipayipi lokunweba elishisayo liwukuthi, thina ngokuvamile bathi ukunwetshwa okushisayo kwepayipi, ukuminyana kuphansi, kodwa ukufinyeza ipayipi eliqinile lensimbi, (ipayipi lensimbi engenamthungo) lingabizwa ngokuthi ukunwetshwa okushisayo.
