Isethi Yezinsimbi Zokubhoboza

Iziphathimandla ze-cluster hammer zimelela isigaba esikhethekile semishini yokudrill yangaphansi komhlaba esiyilwe ukuze isetshenziswe emisebenzini eqinile yezenzo zesisekelo esijulile kanye nezobuchwepheshe behlathi. Lezi ziphathimandla ziqukethe ama-DTH hammers amaningi asebenza ngomkhawulo ofanayo ngaphakathi kwediphozithi elilodwa noma ediphozithini ezikahle, okwandisa kakhulu ukusebenza kahle kokushaya nokusebenza kahle uma kuqhathaniswa nezilungiselelo zodwa. Indlela ye-cluster ihl distribute imiphumela yokudubula phakathi kwezimvubelo eziningi, ivumela abathengi ukuba benze imisebenzi yokumba izintuli ezinkulu, ukuhlanzwa kwesikhala, kanye nezinhlelo zokufaka ama-pile amakhulu ngaphakathi kwezikhawu eziphusile. Le teknoloji ibaluleke kakhulu emsebenzini wezisisekelo lapho ukuphuma kwensimu kwi-rock strata efanele, umhlabathi onamathiselwe, noma umhlabathi oqinile kudingeka ukuba kube nokuqhubeka kokusebenza kwephrojekthi kanye nezindleko zokwakha. Indlela yokusebenza yeziphathimandla ze-cluster hammer isebenzisa ukuthumela amandla okubhoboza ukuze ikhuphulwe izinga lokungena ngenkathi kugcinwa ubunjalo bendawo ezungezile. I-DTH hammer ngayinye ye-cluster ikhiqiza imiphumela ethile yokudubula ethunyelwa ngezoqondisi ezikhethekile, kuyilapho ukuhamba kwamanzi okudrilli phakathi kwezinjini kuqinisekisa ukuncibilika, ukugcotshwa kwezinyathelo, nezixazululo zokuhlanza. Ukwakheka kwephathimandla kuvumela abathengi ukuba bakhethe usayizi wehammer nezincazelo ezifanele izimo zomhlabathi nezindawo ezitholakele ngesikhathi sokuhamba kokudrill, ukusuka kumathafa amathambile kuya kumathekeli aphukile. Le ndlela iyadingeka emisebenzini yeziqalo ezinzima edlula izimo zomhlabathi ezahlukene ezidinga izinhlelo zokudrill ezilungele ukwakheka. Ukuklama kobuchwepheshe kweziphathimandla zohlu lokuhlanganyela kubandakanya izinhlelo zokuhambisa ezikhangayo nezakhiwo zokuqondisa eziqinisekisa ukuhlela kahle nokusabalalisa amandla, ukuvikela ukuphazamiseka phakathi kwe-hammers ezikhaliphile ngenkathi kuthuthukiswa ukusebenza komphakathi. Izicelo zeziphathimandla ze-cluster hammer ziphakathi kwemikhakha ephelele yezenzo zesisekelo esijulile. Ekwakhiweni kwezindonga ze-diaphragm, izimo ze-cluster zivumela ukuhamba kwezitina ngokushesha ezimweni eziyinselele zezwe ngesikhathi kugcinwa ukuhlela okunembile kwezakhiwo nezincazelo zobubanzi bezindonga. Imisebenzi yokukhuphuka kwama-cassion isebenzisa iziphathimandla ze-cluster ukuze ihlanzeke kwi-rock layers ezinqamula izigaba ezifanele zokuthwala, lapho amandla okudubula atholakalayo evumela ukususa kahle ama-cobbles, ama-boulders, kanye ne-rock efanele ezozokwenziwa ngayo ukuphasa kwe-cassion okujwayelekile. Imisebenzi yokufaka ama-barrette kanye ne-secant pile amakhulu isebenzisa ubuchwepheshe be-cluster ukuze ibhukhwashe izikhala zokudrill ezimweni zomhlaba ezihlangene, okuhlanganisa nezindawo ezithile, i-rock ewumshini, nezindawo ze-bedrock eziphathekayo ezivamise ukuba sezingqinisweni zokwakha edolobheni. Imisebenzi yesakhiwo sasezindaweni ezinjengezindonga zezitimela, ukumba okujule, kanye nezinto zokwakha zezikhwama ze-metro zisetshenziswa kaningi iziphathimandla ze-cluster hammer lapho ukusebenza kahle kokudrill kuthinta ngqo ukwamkelwa kwephrojekthi kanye nezindleko zokwakha. Ukukhetha nokuchaza iziphathimandla ze-cluster hammer kudinga ucwaningo olunembile lwe-geotechnical kanye nokwakheka komhlaba ukuze kuhlanganyele ukwakheka kwezindawo ezisezindaweni ezingaphansi. Izinto ezifaka phakathi izinga elilindelekile le-rock, ukujula komhlabathi, izimo zamanzi asenkundleni, izidingo zokuhamba kwamanzi okudrilli, kanye nezithiyo zemvelo z tutto omiba uthinta ukukhetha kwe-hammer, izilungiselelo zokusebenza, kanye nomklamo wesistimu yokuhamba. Iziphathimandla ze-cluster zanamuhla zixhumana nezinkundla ze-drilling rig ezithuthukisiwe ezinikeza ukubheka koutshalo kwe-penzeni, ukulawulwa okukhaliphile, kanye nezinto zokuhlanganisa edokhumenti ukwenza ngcono ukusebenza nokuhlinzeka ngokuqinisekisa okubalulekile kwezimfuno zokwamukela izisiphetho eziyisisekelo neziqondiso ezisemthethweni emkhakheni wezokwakha wanamuhla.
