Amathuluzi Okukhulisa I-Toe (I-Base Reamers)

Emkhakheni wobunjiniyela bezisekelo ezijulile kanye nezobuchwepheshe bezindawo, amathuluzi okwandisa umphambili, avamise ukubizwa ngokuthi izikhala ezisemqoka, ayizinsiza ezibalulekile eziklanyelwe ukuthuthukisa ukuzinza nokuphathwa komthwalo kwezisekelo. La mathuluzi akhethekile okubhoboza asetshenziselwa ukwandisa umphambili wezinsika ezibholile noma uphahla, uqinisekisa ukusebenza kahle okungcono kanye nokwakhiwa kwesakhiwo okuqinile ezimweni zomhlaba ezihlukene. Ngokuphumelela ukwandisa isisekelo somphakathi, izikhala ezisemqoka zenza kube lula ukusabalalisa umthwalo nokuthuthukisa ukumelana nezinsaba eziseceleni, okubalulekile ezifundweni ezifana nokwakhiwa kwamabhuloho, izakhiwo eziphakeme, nezinye izinhlelo ezinzima zokwakha. Imisebenzi yamathuluzi okwandisa umphambili ibandakanya umsebenzi o unikayo ovumela ukuphathwa kokwandiswa okuphathelene nesizinda somhubhe. Ngokuvamile efakwe kumshini wokubhoboza, la mathuluzi asebenzisa uchungechunge lwamakhono okusika noma amabhla, avula futhi angene emhlabathini noma emathuluzini lapho ebholwa khona. Lokhu kuqeqeshwa kudala umhubhe onedijithi enkulu, ongafaka izakhi zokuphakamisa kanye nokuthuthukisa ukusebenza okujwayelekile kwesakhiwo. Ngokulawula kahle inqubo yokubhoboza, onjiniyela bezobunjiniyela bangakwazi ukufinyelela ezilinganisweni ezinembile, okuvumela indlela efanele kumaphrojekthi ngamunye ngenkathi kunciphisa ingozi yokuphazamiseka komhlaba. Izicelo ezibalulekile zezikhala ezisemqoka emsebenzini wezisekelo ezijulile zifaka ukufakwa kwezinsika ezibholile, ama-pile akhishwa nge-augur, kanye ne-micropile. La mathuluzi ayasiza kakhulu ezimweni zomhlaba eziyinkimbinkimbi, njengalezo ezitholakala ezindaweni zasemadolobheni noma ezindaweni ezinoshintsho lwamanzi aphezulu, lapho izindlela zendabuko zokwakha zingase zinganelisi. Ngaphezu kwalokho, amathuluzi okwandisa umphambili abalulekile uma kubhekwa izinhlobo zomhlaba ezahlukene, kufaka phakathi ama-clay amakhulu, i-sand enzima, kanye ne-substrates eziqina, njengoba angakwazi ukwandisa kakhulu amandla okuphatha umthwalo wezakhiwo ezisemqoka. Izincazelo ezijwayelekile zamathuluzi okwandisa umphambili zifaka phakathi uchungechunge lokukhethwa kwemilinganiselo, engahluka ukusuka kumamitha angu-12 kuya ngaphezulu kwe-60, kuye ngezidingo zephrojekthi. Ukwakhiwa kwezinto zezikhala ezisemqoka kuvamise ukuba ne-stainless steel enamandla, eyenzelwe ukumelana nezimo ezinzima zokubhoboza. Ngaphezu kwalokho, izici ezifana nezinhlangothi ezishintshashintshayo zokusika nezikhathi ezilungisekayo zenza kube nokuguquguquka ngakusasa ukusebenza kahle ngesikhathi sokubhoboza. Ngesikhathi sokukhetha ithuluzi elifanele lokwandisa umphambili kwezinhlelo ezithile, kunezimo eziningi okufanele zicatshangelwe ukuqinisekisa ukusebenza kahle. Izinto ezifana nohlobo lomhlaba, ubude obufunayo besisekelo, nezidingo zomthwalo zidlala indima ebalulekile ekuqondeni ithuluzi elihamba phambili. Kubalulekile futhi ukuhlola ukuvumelana kwezikhala ezisemqoka nezinsiza zokubhoboza ezikhona kanye nezindlela, nokuqonda noma yiziphi izinqubo noma izinqumo zezemvelo ezingase zibe nomthelela ekukhetheni amathuluzi. Ngokuvamile, amathuluzi okwandisa umphambili (izikhala ezisemqoka) yinsiza ebalulekile emkhakheni wezisekelo ezijulile kanye nezobunjiniyela bezobuchwepheshe, ehlinzeka ukuzinza okuthuthukisiwe nokuphathwa komthwalo kwezimpi zomsebenzi. Ikhono laMathuluzi ukwandisa izisekelo zomphakathi ezimweni zomhlaba eziyinkimbinkimbi kwenza kube ngabalulekile kumabhizinisi nabajiniyela bahlale, kuqinisekisa ukuthi izisekelo zingahlangabezana nezidingo zokwakhiwa zanamuhla ngenkathi zigcina izindinganiso zokuphepha nokusebenza.
