Umshini wokukha umkhondo ophumelelayo onamathiselwe nezici zokukhipha amanzi uhambisana nesixazululo esihlangene sokwakha izisekelo ezijulile, sihlanganisa ukufakwa kwemikono encane nephuma emhlabeni, ukwelashwa komhlaba nokuzinza. Le mfuneko yeqembu lemishini isiza abaqashi abadinga izixazululo eziguquguqukayo zobunjiniyela obungaphansi, lapho ukufakwa kwemikono okujule kwejwayelekile kungasebenzi ngenxa yezinkinga zendawo, izidingo zokukhanda, noma izimo zomhlaba ezidinga ukuhlanganiswa kokuzinza nokusekelwa kwezisekelo. Umshini wokukha umkhondo unciphisa umthamo wezakhamzimba zezakhiwo, kuyilapho uhlelo oluhlangene lokukhipha amanzi lwenza ukwelashwa komhlaba, ukunciphisa ukuqina, nokwandisa amandla ngesikhathi esisodwa, kunciphisa isikhathi semisebenzi yonke nendawo yokusebenzela. Lezi zinhlelo ngokuyinhloko zithunyelwa emisebenzini yokwakha izisekelo ezishisayo nezokuphinda zisetshenziswe, lapho izakhiwo ezikhona zidinga ukuqiniswa kwezisekelo ngaphandle kokuhlanganiswa. Zikahle kakhulu ekwakhiweni kwezifinyo ezisekelwe ekukhipheni emisebenzini yokwakha amadamu, ekulungiseni izindawo zokungcola, nasekuphathweni kwamanzi emhlabeni. Emiphakathini yamawindi e-diaphragm, ukuhlanganiswa kuvumela ukwakhiwa kwesikhumbuzo se-secant noma se-tangent ngesikhathi sokwenza ukwelashwa lokukhipha emhlabeni ukuze kufezwe izincazelo ezidingekayo zokuqina. Ngaphezu kwalokho, leli qembu lemishini lisekela imisebenzi yokuhlanganisa umhlaba ukuze kuthuthukiswe umhlaba ophonsele umoya noma ophakanyisiwe lapho ukwandisa amandla akhulu kuqala kugcwaliswa. Iphakheji yokusebenza ihlanganisa izindlela zokubhola ezibhalwe noma eziphathekayo zokufaka imikono encane namasistimu okukhipha amanzi ahlwitha umoya ngokpressure ephezulu. Ngesikhathi sokuthuthuka kwemikono encane, i-casing ngokuvamile ijubane ngokuhamba yonke imikhawulo yomhlaba, ngenkathi izinsiza zokubhola zangaphakathi zishintsha. Uhlelo lokukhipha umoya oluhlanganisiwe—olusebenza ngokuzimela noma ngasikhathi sinye—lufaka i-slurry ye-cement imbobo ephezulu ejula phakathi kwemijikelezo eminingi ethunyelwe kulodzi lwezokwelapha. Le ndlela ye-dual ivumela ukwelashwa komhlaba okukhethiwe ngaphambi kokufakwa kwemikono encane, ngemuva kokuthola ukuhanjiswa kwezimali nokusebenza kwezakhiwo. Ingxenye yokukhipha amanzi idala iziqeshana ezihambisana noma eziyimigqa ezilinganiselwe kuya kwemigudu yokufaka (monojet, bijet, noma trijet systems) kanye noqhubekela phambili komshini. Ukulungiswa kwemishini phakathi kwalesi sigaba kuhluke kakhulu kuye ngaphezu okukha okukhulu (ngokuvamile 10-50 metres), ububanzi bemikono encane (150-350 mm), izinga lokucindezela lokukhipha amanzi, nezidingo zokumobilisa. Ukulungiswa kwemishini kuhlanganisa idivayisi encane, efakwe kumjikelezo efanelekayo ezindaweni ezizimele ukuze kutholakale kahle, ukuya kumasistimu amakhulu afakwe ezikhumbeni ukuze kutholakale izinga eliphakeme lokukhiqiza. Izitshalo zokuhlanganisa, izinhlelo zokuhlola ingcindezi, nezilawuli ezizenzakalelayo zokuphakamisa/ingcindezi zimele izici ezijwayelekile. Izimfanelo ezisemqoka zifaka ukuphakamisa okuphezulu okuphezulu, ubukhulu be-grout kanye ne-capacity pressure, ukunciphisa i-OD ye-casing, kanye nezinketho zokuhlanganiswa kwe-jet grout eziphuma kwe-module. Ukukhetha imishini kuhlola izimfanelo eziningi zobuchwepheshe: i-stratigraphy yasemhlabeni nempumelelo yemigudu, izidingo zemikono encane yokuthola amandla okuhlola nezimfanelo zempahla, ukubalwa kokwelashwa kwe-jet grout kanye nezincazelo ububanzi, isikhala esikhona sokusebenza kanye nezinqwaba zomkhiqizo, kanye nezikhathi zephrojekthi. Abakhi kumele bahlola ukuthi ukufakwa kwemikono encane nokukhipha amanzi ngesikhathi esisodwa noma emisebenzini elandelanayo kuhloswe kahle ngezidingo zephrojekthi. Ukujula kwamanzi emhlabeni nezidingo zokuphathwa kwe-tala yamanzi kuthinta izinto zezikamu nezinhlelo zokucindezela. Izindinganiso zokwakha nokusebenza ezisebenzayo zifaka phakathi i-EN 14199 (imikono emincane), i-EN 14490 (izixhumi zomhlaba nezinyathelo), i-ISO 13761 (ukukhipha amanzi), kanye ne-DIN 4128 (ukukhipha amanzi), ngemigudu yendawo ebheka izicelo zendawo zokuqeqeshwa kwe-geotechnical nemithetho yokuhlala.
