Ukunemba kwesikhathi eside kombhede wamathuluzi omshini we-granite oqediwe kunqunywa kakhulu ngesikhathi kukhethwa indawo engenalutho yetshe eluhlaza. Amaphrojekthi amaningi ahlushwa ukukhukhuleka okunembile, ukuguquka kwendawo, noma ngisho nokuqhekeka okungazelelwe ngesikhathi somshini wokugaya kamuva. Imbangela eyinhloko ngokuvamile akuyona inqubo yokugoqa, kodwa ukuhlolwa okunganele ngesikhathi sokukhetha okungenalutho. Abathengi abaningi bamane bahlulele itshe ngombala walo wobuso ngenkathi bebheka izinkomba ezifihliwe njengokwakheka kwamaminerali angaphakathi, ukuqhekeka okuncane kanye nezimo zokucindezeleka. Amaphutha atholakala kuphela esigabeni somshini wokugaya, okuholela ekubambezelekeni okubizayo kanye nokulahlekelwa kwezinto ezibonakalayo. Ukukhiqiza imibhede yamathuluzi omshini we-granite kudinga isethi ephelele yezindlela zokuhlola zokukhetha okungenalutho, ukumboza ukuhlolwa komthombo we-ore, ukutholwa kwamaphutha angaphakathi kanye nokuhlolwa kokuthatha amasampula empahla ebonakalayo.
Umthombo we-ore usebenza njengendawo yokuqala yokuhlola ikhwalithi engenalutho. Akuwona wonke ama-granite amnyama afanelekela ukukhiqiza imibhede yamathuluzi omshini onembile kakhulu. Imizimba yamadwala evela emithanjeni ehlukene iyahlukahluka kakhulu ngesilinganiso sezinhlayiya zamaminerali kanye nokuqukethwe kokungcola. Ezinye imizimba ye-ore iqukethe izilinganiso eziphakeme ze-mica ne-feldspar, okwenza izinto zibe mnene ngamandla abuthakathaka okubopha phakathi kwamakristalu angaphakathi. Izinto ezinjalo zivame ukulahla okusanhlamvu ngesikhathi somshini. Ngaphansi kokushintshashintsha kwezinga lokushisa le-workshop isikhathi eside kanye nokudlidliza okuncane, ubulukhuni bomphezulu walo buzoqhubeka nokuwohloka. I-ZHHIMG ikhetha ngokukhetha i-granite emnyama enobukhulu obuphezulu emithanjeni ye-ore ezinzile. Idwala liqinile futhi liyafana ngesilinganiso se-quartz esifanele kanye namakristalu amaminerali axhumene ngokuqinile. Lokhu kunikeza indawo engenalutho ukwanda okuphansi kokushisa kanye nokuqina okuphezulu, kususa izingozi zokunemba ezibangelwa ukungalingani kwezinto kusukela ekuqaleni.
Ukuhlola okubonakalayo kungabona kuphela amaphutha asobala ebusweni futhi akukwazi ukubona izinkinga zangaphakathi ezifihliwe ngaphakathi kwetshe. Ama-microcracks angaphakathi angabonakali, ama-interlayer kanye nama-voids amelela izingozi ezinkulu zezikhala. La maphutha agqitshwe ngaphakathi kwetshe futhi ahlala engatholakali esigabeni sokuqala sokusika. Kodwa-ke, imifantu izokhula kancane kancane ngesikhathi sokusika okulandelayo, ukugaya okuqinile, kanye nokulayisha okwenziwa ngomshini isikhathi eside kanye nemijikelezo yokushisa eshintshashintshayo yamathuluzi omshini, okulimaza ngqo ireferensi yombhede. Ngemva kokuba izikhala zifikile efektri yethu, senza ukuskena kwendawo yonke kwebhulokhi ngayinye elukhuni ngokutholwa kwamaphutha e-ultrasonic ukuze siphawule ngokugcwele izindawo zokuqhekeka kwangaphakathi kanye nama-interlayer ahlukene. Izikhala ezinemifantu engena ngaphakathi noma ama-interlayer amakhulu akhululekile zenqatshwa ngqo. Uma kunezinkinga ezincane zendawo, sihlola ukuthi zisezindaweni ezithwala ukucindezeleka noma ezindaweni zokusebenza zereferensi zombhede ukuze sinqume ukuthi sizosusa yini ingxenye enephutha noma silahle yonke indawo engenalutho.
Ukuhlola izakhiwo ezibonakalayo kuyimbangela yokukhetha okungenalutho. Ubuningi, i-coefficient yokwanda kokushisa kanye ne-modulus elastic kungashintshashintsha ezindaweni ezahlukene zebhulokhi elilodwa eliyi-rough. Ukwahlulela ikhwalithi yezinto ezibonakalayo ngokusekelwe emibikweni ye-batch ore akwanele. I-ZHHIMG ithatha amasampula ezindaweni ezigodliwe ezingashintshwanga ngomshini zezimbobo ukuze kuhlolwe izakhiwo ezibonakalayo, igxile ezinkombeni ezibalulekile kufaka phakathi ubuningi (cishe u-3100kg/m³), i-coefficient yokwanda kokushisa, ukumuncwa kwamanzi kanye ne-modulus elastic. Ukumuncwa kwamanzi kufanele kuqashelwe ngokukhethekile. Itshe elimuncwa amanzi amaningi linezimbobo eziningi. Limunca kancane futhi likhiphe umswakama ngokushintsha komswakama ozungezile, okuholela ekwandeni kancane kancane kwevolumu kanye nokufinyela kanye nokubangela ukugeleza kokubhekisela. Izimbobo kuphela ezinemingcele ezinzile nefanelekile yomzimba ezingaqhubeka nokusika.
Isimo sokucindezeleka kwangaphakathi kwezikhala sishaywa indiva kalula. I-granite yemvelo yakheka ngaphansi kwengcindezi ye-strata engaphansi komhlaba. Ukumba nokusaha kukhulula i-geostress yokuqala futhi kushiye ukucindezeleka okusele ngaphakathi kwesikhala. Uma isikhala singaphathwa ngokwanele ukuguga, ukucindezeleka kuzosabalala kabusha ngemva kokususwa kwezinto ezinkulu ekushiseni okuqinile. Lokhu kubangela ukuguquguquka okugoba kancane kwengxenye futhi kuqeda ngokushesha ukuthamba okutholakala ekugobeni kwangaphambilini. I-ZHHIMG isebenzisa ukuguga kwemvelo okude ezindaweni ezikhethiwe ukuze ikhulule ukucindezeleka kwangaphakathi okusele, kulandelwe ukuhlolwa kabusha kwesibili. Umjikelezo wokuguga welulwa ngokufanele ezindaweni ezinkulu zemibhede yemishini esindayo, ukuqinisekisa ukuthi akukho ukuguquguquka okuzenzakalelayo ngemva kokuqeda ukusebenza.
I-geometry engenalutho kanye nokuhlela isibonelelo somshini nakho kuyasekela amaphuzu ekukhetheni izinto. Uma kulinganiswa amabhlogo aqinile, isibonelelo somshini esifanele kumele sigcinelwe ukubala ukulahleka kwezinto ekusikeni, ekugayeni okuqinile, ekugugeni nasekuhlanganiseni kahle. Isibonelelo esinganele sisho ukuthi yonke indawo engenalutho izosuswa uma kutholakala amaphutha afihliwe ngesikhathi somshini oqinile. Isibonelelo esiningi kakhulu sandisa izindleko zokucubungula kanye nemijikelezo yokukhulula ukucindezeleka. Ngaphezu kwalokho, izendlalelo zangaphandle ezigugile zamabhlogo aqinile kumele zigwenywe. Ingqimba engaphezulu yemizimba yensimbi ikhululwa ukuguguleka kwemvelo kwesikhathi eside futhi akumelwe isetshenziswe njengendawo yokusebenza ebhekisela emibhedeni yomshini. 
Amakhasimende amaningi awela embonweni ovamile oyiphutha: ukugxila kuphela ebulukhunini obungenalutho. Nakuba ubulukhuni bubalulekile, izikhala zemibhede yamathuluzi omshini zidinga ukusebenza okulinganiselayo kwazo zonke izinkomba zomzimba. Itshe elinobulukhuni obuphezulu kodwa elizinzile ekushiseni okuphansi kanye nokuqhekeka kwangaphakathi okuningi alikafaneleki njengesisekelo semishini yokunemba. Ingqikithi yokukhethwa kwezinto itholakala ekusebenzeni okuphelele: izinto ezifanayo, ukucindezeleka okuphansi okusele, ukwanda okuphansi kokushisa kanye nokuncishiswa okuphezulu, kunokuba kube nenani elikhulu kakhulu lepharamitha eyodwa.
Isebenzisa iminyaka eminingi yokuhlangenwe nakho kokukhiqiza izingxenye ezinembile kakhulu, i-ZHHIMG isungule uhlelo oluphelele lokuhlola olungenalutho. Izikhala zegranite ezifanelekayo zemibhede yamathuluzi omshini, ozimele be-gantry kanye namapulatifomu okuhlola zihlolwa isinyathelo ngesinyathelo ngokukhetha umthombo we-ore, ukutholwa kwamaphutha e-ultrasonic, ukusampula ngokomzimba kanye nokuguga kokucindezeleka. Ngaphandle kwegranite, singaqhathanisa ezinye izinto eziyisisekelo ezifana nokuphonswa kwamaminerali kanye ne-UHPC ngokwezimo zokusebenza kwephrojekthi futhi sincome ikhambi lezinto eziyisisekelo ezifanele kakhulu kumakhasimende.
Ukukhetha okungenalutho kwemibhede yamathuluzi omshini we-granite akuxhomekile nje kuphela ekubukekeni kodwa futhi nasekhwalithini yangaphakathi engabonakali. Ukuhlolwa okuqinile okungenalutho kunganciphisa kakhulu izingozi zokukhuhla ekucutshungulweni okulandelayo futhi kuqinisekise amazinga aqinile ejometri emibhede eqediwe iminyaka eminingi yenkonzo. Kusebenza njengesisekelo esidingekayo sokusebenza kwemishini isikhathi eside ngokunemba okuphezulu.
