Ama-pump amelela imishini ebalulekile kwi-engineering ye-geotechnical yesimanje kanye nokwakhiwa kwezingqimba ezijulile, apheshelisa imisebenzi ebalulekile ezinhlelweni ezahlukene zokuzinza komhlabathi, ukuphathwa kwe-slurry, kanye nezicelo zokuthuthukiswa komhlaba. Emkhakheni wezokwakha okukhulu kwepiling, ama-pump anciphisa ukuhamba nokufakwa kwemifula yokubhoboza, i-grout, nezixazululo ezikhethekile ze-slurry ezisekela ukuvikeleka kwe-bores, ukufakwa kwe-casing, kanye nokwethembeka kwesizinda. Lezi zinhlelo ziphathe izixazululo ze-bentonite ezinoketshezi oluphezulu, amafutha okubhoboza e-polymer, kanye nezixazululo ze-cementitious grout ezidinga ukugcina imilinganiselo ethile yokuhamba kanye nezidingo zengcindezi ngokuya ngezimo zomhlaba, ubukhulu be-bores, kanye nokusebenza okukhethekile kwezingqimba okusetshenziswayo. Nokho, njengoba kusekelwe kumagibeli owakhelwe ukuhamba, izinhlelo ze-CFA (Continuous Flight Auger), noma ukwakhiwa kwezingqimba ze-diaphragm, imishini yokuphonsela ingcindezi ithonya ngqo ukusebenza kahle kanye nekhwalithi yomsebenzi ongaphansi emhlabeni ophilayo, emanxiweni e-sandy, nasemithanjeni ehlangene, evamile ezindaweni zokwakha zasemadolobheni. Uhlanga lwetekhnoloji ye-pump esebenziswe kuhlu lwezosingathwa komhlaba luveza isimo esinzima sokusebenza kwe-geotechnical, kuhlanganisa ama-pumps omnqamuleli for circulations ye-slurry enkulu, ama-pump we-cavity ahamba phambili okusingatha amafutha okubhoboza avukile namasuspensions enesikhumba, kanye nama-pumps we-piston akwazi ukukhiqiza ingcindezi ephakeme edingekayo yokufaka i-grout kanye nezicelo zokugruva nge-jets. Uhlobo ngalunye lwe-pump luhlangabezana nezidingo ezithile zokusebenza: ama-units omnqamuleli akhombisa ukukwazi ukuphatha izixazululo ze-bentonite ezinkulu ngesikhathi sokukhucululwa kwe-bores, kanti ama-screw pumps e-ecentric kanye nezinhlelo ze-peristaltic zikhombisa ukubaluleka kokuphathwa kwezinto ezibucayi kanye ne-grouting enembile. Ama-pump e-diaphragm anika ububanzi emisebenzini emincane nasezicelo ezikhethekile zokuthuthukiswa komhlaba, ikakhulukazi ezindaweni zasemadolobheni ezifakwe kakhudlwana lapho ukuhamba nokunciphisa isikhala sendawo kungama-mkhawulo. Kukhethwa phakathi kwezobuchwepheshe lezi kuye ngesisekelo se-slurry, ingcindezi ephumayo edingekayo, imilinganiso yokuhamba, kanye nokuhambisana nezinsiza zokubhoboza ezikhona. Izimo zomhlaba ziqondisa ngokuqondile izidingo zokuphonsela nokwakheka kwe-slurry emaphrojeni okwakha. Kwi-clays ezithambile nasemithini, ama-bentonite slurries aqhubekayo anesisindo esiphansi agcina ukuvikeleka kwe-bores ngaphandle kwegcindezi ye-hydrostatic ethile engakha ukuzamazama noma ukushintsha komhlaba. Ngakolunye uhlangothi, umhlaba we-granular kanye nezinhlaka eziphukile zidinga izixazululo ezinenhluzeko ephezulu kanye nekhono le-pumping eliqinile ukuze kuvinjelwe ukuhamba kwamathuna kanye nokuhambisa kahle kwe-casing. Imisebenzi yokuhlanza imikhondo kwi-piling ejulile icela ukujikeleza okuqhubekayo kwe-slurry ukuze ithathe izicubu ze-drill phezulu, kanti ukusebenza kwe-pump kubalulekile ukuze kuqinisekiswe ezingeni elamukelekayo lokungena futhi kuvinjelwe ama-pipes agcinwe. Izicelo ze-grouting—kungakhathalekile ngokuthi ziphakathi nezisekelo ze-pile zokufaka, ukuhlanganiswa komhlaba, noma ukulungiswa kwe-seismic—zidinga ama-pump akhethekile angakwazi ukugcina ingcindezi ehambisanayo kuyo yonke izinqubo zokufaka, ngokuvamile ezindaweni ezinzima ze-strata ezine-low-permeability. Imishini yokwelapha i-slurry ibamba iqhaza elithile nemishini yokuphonsela, isebenzisa ama-centrifuge, Izinhlelo ze-decanter, kanye nezitsha zokuhlala ukufaka phambili ukuphathwa kwabakha, futhi kuze kukhule kakhulu ukusebenza kwemishini nokunciphisa izindleko zokukhipha emaphrojekthi amakhulu we-infrastructure. Ukuhlanganiswa kwemiyalo yokuphonsela nemishini yokulandelela ngokuzenzakalelayo kanye nezinhlelo zokulawula ingcindezi kwenza kube nezinqumo eziphelele ngesikhathi sokuqhuba, kukhuphula ukwakheka maphakathi nokunciphisa umthelela wombuso nengozi yokuhamba ezindaweni ezibucayi ezindaweni zokwakha zasemadolobheni kanye nemikhawulo yamanzi.
