Amathangi eGrout

Ama-grout pumps ayithuluzi echwepheshile aklanyelwe ukufaka i-grout enesisindo esiphezulu emgodini nase-micropile shafts, edlala indima ebalulekile prosesi ye-micropiling yokwakha izisekelo kanye nokuthuthukiswa komhlaba. Lezi zinsiza zomshini ezinemininingwane zenza ukuthi abathengisi bakhe ukuqiniswa komhlaba okwethembekile ezimweni zomquba eziyinkimbinkimbi lapho izindlela zokuphilisa ezijwayelekile zingafaneleki noma ezingasebenzi. Ama-grout pumps akhulula ukufuduka okuqondile kwemikhiqizo ye-grout emigodini ehloliwe, akha ubuhlobo obuqinile bokusebenza phakathi kokwakhiwa kwe-micropile okwenziwa nge-steel kanye nematrix yomhlaba ezungezile. Ukuhlinzeka nge-grouting kuyisisekelo sokufeza ubunjiniyela obunempilo kanye namandla okuphatha umthwalo adingekayo ukuze kutholakale izinhlelo zezisekelo ezijulile zanamuhla, ikakhulukazi ezindaweni zasemadolobheni lapho izikhala ezenzakalayo nezakhiwo ezithintekayo zidinga izixazululo ezintsha. Imisebenzi ye-grout pump kwi-micropiling ihilela amasu amaningi abalulekile akhelwe izimo zomhlaba ezithile nezidingo zaphrojekthi. Uku-grouting okujwayelekile kusebenzisa ukujolisa okuphakanyisiwe ukufaka ama-boreholes nge-grout eyenziwe ngocemente, kudala into yezakhiwo ehlanganisiwe eyanelisa ukusekelwa kwemithwalo ye-vertical kanye ne-lateral. Uku-grouting kwe-tube-a-manchette (TAM), enye indlela evamile, kusebenzisa iziteshi zokufaka eziningi eduze kwe-micropile shaft ukuze kuqinisekiswe ukuhambisana kwe-grout ezindaweni ezahlukene zomquba, kuthuthukisa kakhulu ukusebenza kohambo lwemithwalo. Uku-grouting kwe-jet, okuvamise ukusetshenziswa ngokuhlanganiswa ne-micropiling, kusetshenziswa ama-grout streams aneshubhu ephakeme ukuze aphule futhi ahlanganise umhlaba ozungezile, kudala ama-columns omhlaba-ocimile anekhono elikhululiwe. Ukukhetha indlela ye-grouting kuncike ekwakhekeni komquba, izimo zamanzi emhlabeni, izidingo zokujula zephrojekthi, kanye nezincazelo zomthwalo. Izinhlelo zamagrout pumps ezisebenza kahle kumele zigcine umfanekiso othathe phezulu, izinga lokushisa, kanye nezinga lokugeleza ukuze kuqinisekiswe ukusabalala kwe-grout okujwayelekile nokuvimbela ukwehlukaniswa kwezingxenye ze-grout. Izicelo zobuchwepheshe bamagrout pump ziyaqondanisa nakumakethe ezakhiwo ezahlukene ezidinga izixazululo zezisekelo ezijulile. Ukuqinisa izakhiwo ezikhona ezinezisekelo eziphukile noma ezincane kusebenzisa i-micropiling ehlanganiswe ne-grouting eyenziwe ngezingxenye ezinemininingwane, kuvumela ukusabalalisa umthwalo ngaphandle kokuphazamiseka okukhulu kwezinhlelo zokwakha. Ukuhlonipha umhlaba ezimbanje noma eziphakeme, kufaka phakathi isand, izimpushana, kanye nezimfucumfucu, kuba nokuqinisekisa kungaphakathi kwezinhlelo ze-grouting ezilawulwa ezithuthukisa ikhono lokuphatha umthwalo futhi zehlisa ukuncipha. Iziphakamiso zokuphakamisa isikhala sebhala zisebenzisa ama-micropile agqokwe nge-grout ukuze abambe izintaba ezingaguquki futhi avimbele ukuhamba okunamathiselwe. Ezindaweni ezifana nezilwandle nezokwakha ezikhaleni, ama-grout pumps asebenzisa ukwakha izinhlelo zezisekelo ezisanda kubekezelwa ezindaweni ezithambile nezimo ezichazayo. Ukuqiniswa kwe-seismic kwezindlela ezikhona kuncike kakhulu ku-micropile technology, ikakhulukazi ezindaweni ezinamathuba aphezulu e-seismic. Ukuze kuxhaswe, izindlela zomgwaqo, ukuvuselelwa kwezakhiwo, ukusekelwa kwemigudu yokuthutha, kanye nezinhlelo ezinzima ezingaphansi komhlaba zonke zisebenzisa izinhlelo zamagrout pumps ezikhethekile ukuze kufezwe ukufakwa kwezisekelo ezijulile okungabizi, okungathinteki kalula. Izinsiza zamagrout pump zanamuhla zifaka ukulawulwa okuyinkimbinkimbi kanye namakhono okulandelela ukuze kuqinisekiswe ukuqinisekiswa kwemikhakha phakathi kweprosesi ye-grouting. Ukuqapha umfanekiso, ukulawula izinga lokugeleza, kanye nokuphathwa kokushisa kwe-grout kubalulekile ukuze kuqinisekiswe ukuhanjiswa okujwayelekile nokuthola izinkinga ezingase zibe khona ezifana nezithiyo ze-grout noma ukungasebenzi kahle kwemishini. Ukukhetha imishini kuncike esikalini sephrojekthi, ubude obudinga ukufinyelela, usayizi wengxenye ye-holes, kanye ne-pressure yokufaka edingwayo, nezinketho zitholakala okuvumela izinhlelo ezihamba phambili ezimeni zokungena okuvinjiwe kuze kube sezinhlelweni ezinkulu ezenzakalayo zemikhiqizo. Noma ngabe ibhekisela ezimweni zomhlaba ezinzima, ukuqinisa izakhiwo ezidala, noma ukusungula izisekelo ezijulile ezintsha ezindaweni ezikhawulelwe, ama-grout pumps nezinhlelo zabo ze-grouting zimelela ubuchwepheshe obubalulekile kubaklami abangochwepheshe abakhiqizayo izixazululo ezithuthukile ze-geotechnical kanye nezobunjiniyela bezezimali.
