GUPFUKA NEZA IBITERA UBUHEHERE BW’INYUBAKO KU BURYO BW‘INTAMBIKE
1. GUCA INKINGI(inkuta)
Gukata inkuta bishobora gukorwa na wall mill mugihe kurambika bikozwe mu matafari cyangwa ibikoresho bivanze hamwe n’uburemere bugera ku kigero cya 3 kurwego rwa Mohs (ibuye ry’umucanga) kurwego rw’igice kirinda amazi. Mugihe habaye inkuta zitose cyangwa zivanze ku bukomere bwo ku kigero cya 3 kugeza kuri 6 kurwego rwa Mohs, gukata urukuta bikorwa hakoreshejwe umugozi wometseho icyuma. Gukata beto igizwe n’amabuye akomeye bikorwa hakoreshejwe icyuma. Gukata bifite uburebure bwa mm 16-20 bikozwe mu rukuta rwose. Uburebure bwo gukata buterwa n’ uburyo igikuta giteye. Iyo bibaye ngombwa, uburebure bwagabanijwe bugenwa hashingiwe ku mibare ihamye.
2. GUSUKURA IGICE CYAKASWE
Urukuta rumaze gukatwa, igice gisukurwa. Inzira ibanza gukorwa n’intoki, hanyuma – hakifashishwa jet of air ku muvuduko.
3. KURINGANIZA AHATARESHYA
Kugirango habeho guhuza neza ibihagarika amazi mu nkuta , birakenewe kwishyura indinganizo yo gukata ushyiraho iringaniza.
4. KURINDA AMAZI MUBURYO BWINTAMBIKE
Mu gutsindagira igice gitambitse kirinda amazi, ibikoresho byujuje ubuziranenge gusa, bishyirwa mu gice barimo gukata, Ibikoresho bitarinda amazi bigizwe na bituminiyumu yo gushonga, itanga uburyo bworoshye bwo kugerekaho ibindi bitambitse kandi bihagaritse. Ubugari bwuzuye bw’ibice bibiri byegeranye by’impapuro za bitumen ni cm 10. Kwuzuzanya bifatanye na bitumen. Urupapuro rw’icyuma 2mm No 4571 rushobora kandi gukoreshwa mugushimangira urwego rutarinda amazi, mu gihe bisaba kubara neza bihamye
5. GUPFUKA IPFUMURO
Kugirango ushyireho ingingo zidasanzwe kandi ziteye imbere, byihuse solidified air ishyirwa muri beto hakoreshejwe uburyo bwa shotcrete.Nyuma ibyo byavanzwe bigera ku mbaraga za 5 N / mm2 nyuma yiminota 15 yo gushyiraho, na 34 N / mm2 – nyuma yiminsi 28.
