Izinsiza Zokugqokwa Nokufaka

Endaweni yokwakha izisekelo ezijulile kanye nezesayensi ze-geotechnical, imishini yokugrouta nokufaka indima ebalulekile ekuthuthukiseni ukuzinza komhlabathi, ukuthuthukisa amandla okuphathelene, nokuvimbela ukufakwa kwamanzi. Le mishini ekhethekile iklanywe ukufaka ama-grout noma ezinye izinto emhlabathini noma kumafushane, ngempumelelo igcwalisa izikhala, iqinisa umhlabathi ophukile, futhi ivale amafekethisi noma amasela. Le nqubo ivamise ukufaka ukusetshenziswa kwamaphampu aphezulu okuphezulu nemishini yokufaka ehlukene eqinisekisa ukufakwa nokusabalalisa kahle izinto zokugrouta. Imishini yokugrouta nokufaka ivamise ukusebenza ngokusebenzisa izinhlelo ze-hydraulic noma ze-pneumatic ezivumela ukusetyenziswa okulawulwayo kwegrout ngaphansi kwengcindezi. Le ndlela iqinisekisa ukuthi izinto zifinyelela ezindaweni ezibekiwe ngaphakathi kwezitezi zomhlaba, zigcwalise kahle futhi zisebenze kahle. Izinqubo eziningi zokugrouta zifaka phakathi i-permeation grouting, i-compaction grouting, kanye ne-chemical grouting, ngayinye iklanyelwe izimo zomhlabathi ezithile nezidingo zephrojekthi. Ukukhetha i-grout—kungaba i-cement-based, i-chemical, noma i-polyurethane—kuncike eziphumeleni ezifunekayo, ezifana nokuthuthukisa amandla omhlabathi noma ukunciphisa ukujula. Izicelo ezibalulekile zemishini yokugrouta nokufaka emsebenzini wezisekelo ezijulile kanye nezobuchwepheshe zifaka phakathi amaphrojekthi ahlukahlukene. Lokhu kufaka phakathi imizamo yokuthuthukisa umhlaba ehloswe ukuthuthukisa ukusebenza kwemhlaba ophansi noma ongenazindlela, ukukhokhela izakhiwo ezikhona ukuze kuthuthukiswe ukuzinza, nokwakha izivimbelo ezingenamanzi ekwakhiweni komhlaba. Igrouting ibuye ibe nomthelela ekuqaliseni izisekelo ezijulile, njengezinqamuli nezikhwama, lapho isiza ukuqinisekisa ukuthi izingxenye zokwakha zingasekela amalayisi alindelekile kahle. Uma ukhetha imishini yokugrouta nokufaka, izimfuneko ezithile ziwumkhondo. Izinto ezifana nokwakha kwamaphampu, ingcindezi ephezulu yokusebenza, kanye nohlobo lwezinto ezihlangene nemishini kubalulekile. Ngaphezu kwalokho, ukuguquguquka kwemishini ukuze ikwazi ukuphatha izingqimba ezahlukene zegrout nezindlela zokusebenza ezihambisana nezikala zephrojekthi kuyinselele ebalulekile. Izici ezifana nolwakhiwo olukhululekile, ukulungiswa kalula, kanye nokutholakala kwezinsiza ezifana nezinhlelo zokuhlanganisa nemishini yokubheka zibuye zibe nomthelela ekwenzeni izinqumo. Kwisikhala esinokuncintisana sokwakha izisekelo ezijulile kanye nezobuchwepheshe, ukufinyelela kwimishini yokugrouta nokufaka ethembekile kubalulekile kubakhi abafuna ukuhambisa imiphumela esezingeni eliphezulu. Nokho, kungaba ukuthenga noma ukuqasha, kubalulekile ukuhlole izidingo ezithile zephrojekthi bese uzihlela ngokuhambisana namakhono wemishini atholakalayo. Imishini efanele yokugrouta nokufaka ayithuthukisi kuphela ukusebenza kahle nokusebenza kwezokwakha, kodwa futhi ifaka isandla ekuqinisekiseni ubuhle bokuqala kanye nokuphepha kwezakhiwo ezakhiwayo. Ngokutshalwa kwemishini esezingeni eliphezulu, ochwepheshe embonini bangaqinisekisa ukuthi bahlangabezana nezinsuku zokugcina zephrojekthi ngenkathi behlonipha amazinga aphezulu okukhquality nokusebenza.
