Ubume bomhlaba kufuneka buvavanywe.Istrata ethambileyo ifuna ubude be-anchore obude ukuze isebenze.Umhlaba othambileyo uphumela kubukhulu bemingxuma emikhulu kubungakanani obunikiweyo besuntswana (ngenxa yokurhwashaza kancinci kunye nokuphinda-phinda).
Umhlaba kufuneka ulinganiswe ngokucokisekileyo (okt uvalwe phantsi) phambi kokugrunjwa kunye nokubholithwa.Kusenokufuneka ukukala kwakhona ngamaxesha athile ngelixa kusomba.
Iimpawu zomatshini webholithi kufuneka zilungele iimeko zomhlaba, ubude bebholi kunye nepateni yokubhobhoza.Uvavanyo lokutsalwa kufuneka lwenziwe ukumisela i-anchorage yokuqala yeebholithi zokukhuhlana.
Iipleyiti ezibhityileyo okanye ezibuthathaka ziya konakala xa kuxinezeleka ngebholiti ephantsi.Ibholithi inokukrazula ipleyiti ngexesha lofakelo okanye ngokufaka ibholithi.
Umngxuma kufuneka ucocwe kwaye uhlolwe ukuqinisekisa ukuba i-friction bolt iya kufaka kakuhle.Ukwahluka kobubanzi bomngxunya (ngenxa yokwahluka kwamandla oluhlu lwamatye okanye umhlaba ocandeke ngokugqithisileyo) unokuvelisa iiyantlukwano kubuchule bokubambelela kwimiphakamo eyahlukeneyo.
Ukuba imingxuma yombiwe mfutshane kakhulu ngoko ibholithi iya kuphumela ngaphandle komngxuma kwaye ipleyiti ayizukudibana nomgangatho welitye.Ukonakaliswa kwebholi kuya kubangela ukuba kwenziwe iinzame zokuqhuba ibholi kude kunobude bomngxuma buya kuvuma.Umngxuma ke ngoko kufuneka ube ubunzulu bee-intshi ezimbalwa kunobude obusetyenziswayo.
Ubungakanani bomngxuma obufunekayo kwibholithi yokukhuhlana ngowona mba ubalulekileyo wofakelo.Amandla okubamba ibholithi axhomekeke kwinto yokuba umngxuma uncinci kunobubanzi bebholiti.Umngxuma omkhulu xa uthelekiswa nobubanzi bebholiti, ungaphantsi kwamandla okubamba (ubuncinci ekuqaleni) ) kunye nentsimbi egobileyo.
Ukuba ubungakanani bomngxuma buncinci kakhulu xa kuthelekiswa nobukhulu bokukhuhlana kuya kuba nzima kakhulu ukufaka ibholithi.Ibholithi ingonakala okt i-kinked okanye igobe xa ifakiwe.Imingxuma engaphantsi kobukhulu idla ngokubangelwa ngamasuntswana agugileyo kunye/okanye ubungakanani obungalunganga obusetyenziswayo.Ukuba intsimbi edityanisiweyo isetyenziswa kunye nesivalo okanye ijackleg, idiameter yomngxuma iyancipha ngotshintsho ngalunye lwentsimbi (ukwenza okuqhelekileyo kufuna ukuba kusetyenziswe amasuntswana amancinane njengokugrumba nzulu emngxunyeni).Ngokucuthwa ngakunye komngxuma umthamo we-anchorage uyanda.Intsimbi edibeneyo idla ngokukhokelela kwimingxuma egoso kwaye kufuneka igwenywe xa kunokwenzeka.
Kwibholiti ye-friction yeenyawo ezi-5 okanye ezi-6, isivalo okanye i-jackleg iya kuqhuba ibholithi emngxunyeni kwimizuzwana eyi-8 ukuya kwe-15.Eli xesha lokuqhuba lihambelana ne-anchorages efanelekileyo yokuqala ye-stabilizer.Amaxesha okuqhuba ngokukhawuleza kufuneka asebenze njengesilumkiso sokuba ubungakanani bomngxuma bukhulu kakhulu kwaye ngaloo ndlela i-anchorage yokuqala yebholithi iya kuba sezantsi kakhulu.Amaxesha amade okuqhuba abonisa ubungakanani bemingxuma emincinci mhlawumbi ebangelwa kukuguga kwebit.
Amaqhosha amaqhosha aqhele ukuya kuthi ga kwi-2.5mm ubukhulu kunobungakanani bawo obucwangcisiweyo.Iqhosha le-37mm linokuba yi-39.5mm ububanzi xa litsha.Oku kukhulu kakhulu kwi-friction ye-39mm.Amaqhosha amaqhosha anxiba ngokukhawuleza nangona kunjalo, ukwandisa umthamo we-anchorage kunye nokunyusa amaxesha okuqhuba.Amasuntswana oMnqamlezo okanye "X", kwelinye icala, alingana ngokwenyani ukuya kubungakanani besitampu ngokwesiqhelo ngaphakathi kwe-0.8mm.Babamba igeyiji yabo kakuhle kakhulu kodwa bakholisa ukugrumba kade kuneebhithi zamaqhosha.Kukhethwa ukuba kufakwe amaqhosha ofakelo lokukhuhlana apho kunokwenzeka.
Iibholiti kufuneka zifakwe kufutshane ne-perpendicular kumphezulu wamatye kangangoko kunokwenzeka.Oku kuqinisekisa ukuba umsesane odityanisiweyo unxibelelene nepleyiti ngeenxa zonke.Iibholithi ezingagungqiyo kwipleyiti kunye nomphezulu wamatye ziya kubangela ukuba iringi ilayishwe kwindawo enokuthi ibangele ukusilela kwangoko.Ngokungafaniyo nezinye iibholiti zamatye, iiwasha zezitulo ezingqukuva azifumaneki ukulungisa i-angularity enezinzisi ezikhuhlanayo.
Izixhobo zomqhubi kufuneka zidlulisele amandla e-percussive kwi-bolt ngexesha lokufaka, kungekhona amandla ajikelezayo.Oku kuchasene nezinye iindlela ezininzi zenkxaso yomhlaba.Isiphelo se-shank somqhubi kufuneka sibe ubude obufanelekileyo bokuqhagamshelana nepiston yokubhoboza kwizitophusi kunye ne-jacklegs (okt 41/4" ubude bentsimbi ye-7/8 "hex drill).Isiphelo se-shank kubaqhubi singqukuva ukuze singabandakanyi ukujikeleza kwe-drill.Izixhobo zomqhubi kufuneka zibe nesiphelo esifanelekileyo sokumila ukuze singene kwi-friction ngaphandle kokubopha kunye nokwenza umonakalo kwi-bolt ngexesha lofakelo.
Imfundo eyiyo yabasebenzi basezimayini kunye nabaphathi inyanzelekile.Njengoko utshintsho lwabasebenzi luxhaphakile xa kuthelekiswa nabasebenzi abafaka iibholiti, imfundo kufuneka iqhubeke.Abasebenzi abanolwazi baya konga imali ekuhambeni kwexesha.
Ufakelo kufuneka lubekwe esweni ukuqinisekisa ukuba iinkqubo ezifanelekileyo kunye nomgangatho zigcinwa.Imilinganiselo yovavanyo lokutsalwa kufuneka iqhutywe ngokwesiqhelo kwizithinteli zokukhuhlana ukujonga amaxabiso okuqala okubambelela.
