Izinsiza Zokuqinisa Eziqhubekayo (SDA)

Ama-Anchor Azenzakalayo (SDA) amelela indlela ehlukile yokuthungela umhlaba esetshenziswa kwezobunjiniyela bokwakha ukuze kuqinisekiswe ukuzinza okwesikhashana nokokuhlala njalo kweziphakamiso, ukuhlwanyela, nezakhiwo ezingaphansi komhlaba. Ngokuhlukile kumasu wendabuko wokuthungela adinga ama-boreholes aqediwe, ama-anchor azenzakalayo ahlanganisa inqubo yokubhoboza nokufaka ibe umsebenzi oqhubekayo, kwehlisa isikhathi sokufaka kakhulu futhi kuthuthukisa ukusebenza kahle kumaphrojekthi wokwakha izisekelo. Le nkqubo isebenza ngokuphendula futhi ngasikhathi sinye iphakamisa uthuli lwe-drill olunomoya oluhlanganiswe nekhanda lokusika ngaphakathi komhlaba, ifaka izakhi zokuthunga kancane kancane njengoba umshini ubhoboza. Le njongo yokubhoboza nokuthunga ngokuhlanganyela iyenza i-SDA ibaluleke kakhulu ezimeni zomhlaba ezinzima, izakhiwo zekhowe eziphukile, kanye namaphrojekthi lapho izinkulu zomhlaba noma izimo zomhlaba zilinganisa ukufakwa kwama-drilling equipment jikelele. Indlela ye-SDA iyathinteka ezimeni ezahlukahlukene ze-geotechnical kufaka phakathi ama-clay athambile, ama-silt, umhlabathi ogqokile, kanye nezinto eziphukile ezithambile kuya kwezilinganayo. I-specifications yemishini iyahluka ngokuya ngemfuneko yephrojekthi, nezinhlelo ezijwayelekile zinezithuthi zokubhoboza ezine-torque ephezulu, ikakhulukazi ekukhiqizeni ama-holes okuhlaba ahlukaniswe phakathi kwe-76mm kuya kwangu-200mm, kanye nemithwalo eyanele yokuphakamisa ngaphakathi ezikhaleni ezihlanganiswe kahle. Idizayini ye-drill string engaphakathi ivumela ukudluliswa kwe-grout noma ama-stabilizer kemikhemikhali ngesikhathi sokufaka, kwakha ubuhlobo bokwakha phakathi kwe-element ye-anchor nomhlabathi noma igneous rock. Iziphakamiso zokufaka zifaka ama-systems owodwa ovulekile lapho i-grout isetshenziselwa ngesikhathi sokubhoboza, kanye nezinhlelo eziphindwe kabili lapho kubhobhwa kuqala kulandelwa izenzo zokuhlanza emva kokubhoboza. Le nhlobo yokuhlanza i-grouting ivumela ababhakabhaka ukuba baphendule izinqubo zokufaka ezimeni zomhlaba ezithile nezidingo zokusebenza kwephrojekthi. Izinhlelo zokusebenzisa ama-anchor azenzakalayo zifaka izigaba eziningi zezakhiwo okuhlanganisa ukuzinza kweziphakamiso zezintaba zemvelo kanye nezihlalo eziwubuthakathaka, ukwesekwa kwetunela nezakhiwo ezingaphansi komhlaba ngesikhathi sokuhlwanyela, izinhlelo zokubamba izisekelo ezinzulu, kanye nokumelana nomthwalo wezindleko ezakhiweni ezihlaselwe amandla e-seismic noma umoya. Kwamaphrojekthi ezisekelo ezinzulu, ama-systems e-SDA avame ukuhlinzeka ngama-anchor aphezulu eduze kwezakhiwo eziphakanyisiwe, ikakhulu lapho ukwehla komhlaba noma ukuhamba komzimba kudala ingozi ezakhiweni ezikuduze. Le teknolojia ibonakala ihlulekile ikakhulukazi ezindaweni zasemadolobheni lapho ukubhoboza okuphathelene ne-anchor kungakhulisa umsindo, ukuhlikihla, noma ukukhiqiza yonke ivuno engavumelani nezimo ezikhungathekile. Izinhlelo zesikhashana zifaka ukweseka ngesikhathi sokwakha, kanti ukufakwa okungapheli kusebenzisa izinto eziyavumelana nokukhula okukhulu nezici zokuvikela ukuze zisebenze isikhathi eside ezindaweni ezibi zomhlaba noma izizinda zosuku. Ukuhlanganiswa kwesikhathi sokubhoboza esincitshisiwe, ukuthuthukela ezimeni zomhlaba ezihlukahlukene, nokuhambisana nezinhlelo zokuhlanza i-grouting kukhulise ama-anchor azenzakalayo njengezici ezijwayelekile zomsebenzi wezobunjiniyela besimanjemanje be-geotechnical kuma-phrojekthi ensiza yokwakha nezizathu ezidinga izixazululo ezithembekile, ezingasebenzi kahle zokuthunga.
