Ulayini we-hydraulic wobubanzi obuncane obusetshenziselwa ukusebenzisa imishini yokuqedela imigodi engaphansi njengevalvu yokuphepha engaphansi komhlaba elawulwa ngaphezulu (SCSSV).Amasistimu amaningi asebenza ngomugqa wokulawula asebenza ngokuhluleka ukuphepha.Kule modi, ulayini wokulawula uhlala ucindezelwe ngaso sonke isikhathi.Noma yikuphi ukuvuza noma ukwehluleka kuholela ekulahlekelweni kwengcindezi yolayini wokulawula, okusebenza ukuvala ivalvu yokuphepha nokwenza umthombo uphephe.
Imikhiqizo yamashubhu yomkhakha kawoyela negesi isetshenziswe ngempumelelo kwezinye zezimo ezicindezela kakhulu zangaphansi kolwandle kanye ne-downhole futhi sinomlando omude oqinisekisiwe wokuhlinzeka ngemikhiqizo ehlangabezana nezidingo zekhwalithi eziqinile zomkhakha kawoyela negesi.
I-Meilong Tube inikezela ngamashubhu ahlanganisiwe ezinhlobonhlobo zezinsimbi ezingagqwali ezingagqwali, ama-nickel alloys.Sinolwazi olunzulu ekuhlinzekweni kwemikhiqizo kanye nokusungula izinto ezintsha kulo mkhakha, kusukela entuthukweni yezobuchwepheshe edingekayo ekuthuthukisweni kolwandle olungaphansi kolwandle ngo-1999 kuya ezinseleleni zamanzi ajulile zanamuhla.
