Ukubhoboza Okushaywayo Kwesisu

Ukuhlinzwa kwe-rotary core kubalulekile ekwenzeni ucwaningo lwes site phakathi nesigaba semisebenzi yokwakha izisekelo ezijulile, okuvumela ongoti be-geotechnical ukuthola amasampula emhlabathi nemabula angaphazanyiswa ngokuqinile avela ezindaweni ezihlukahlukene. Le ndlela yokhuhla isebenzisa ibhithi yokuhlanza ejikelezayo—ngokuvamile ibharel le-core enezinhlangothi zokuhlanza ezibhalwe nge-diamond noma i-carbide—ukuqhamuka ezindaweni zomhlabathi, umhlabathi onomphela, i-silt, i-sand, i-gravel, kanye ne-bedrock ngenkathi igcina ubunjalo beziqu ezitholakele. Ngaphandle kokuhlanza ngezinsimbi zokushaya noma ukuthakazelela, ukuhlinzwa kwe-rotary core kugcina ukulawula okunembile phezu kwejubane lokuhlanza, ingcindezi, nokuhamba komfutho, okwenza kube yindlela ekhethwayo yokuhlola ngemigqa yokwakha goqiga nolwazi lwe-geotechnical ngaphambi kokuklama nokuqinisekisa izisekelo ezijulile. Inqubo yokuhlinzwa kwe-rotary core ihilela ukunciphisa ibharel le-core elihambiswayo elinokuhlakanipha kokuhlanza ngegumbi elikhethekile, lapho amandla okujikeleza ahlanganiswa nengcindezi ephansi adala isenzo sokuhlanza esifana nesiyingi esikhipha isampula ye-core esiyindilinga. Umfutho wokuhlinza—ngokuvamile amanzi, i-bentonite slurry, noma i-polymeric mud—usebenzisa izinjongo eziningi: ukususa izigaxa eziphumile ebhodeleni, ukuhlinzeka ukuhlinzwa kwembobo, ukunciphisa ukunqoba nokushisa ebezihlinzwa, nokwakha indlela yokubuyisela amasampula angaphazanyiswa. Abakhi bezinsizakalo ze-geotechnical basebenzisa imishini ethize yokuhlinzwa kwe-rotary core efakwe kumashini ewashiyiswa enziwa ngemoto, izinyawo ezihamba phambili, noma ama-skids ukuze bangene ezindaweni zokusebenza ezikhethiwe ngenkathi begcina ukunemba okudingekayo kokuhlukanisa umhlaba. Lezi zinsiza zifaka phakathi ama-mast wokuhlanza anokufinyelela kokuqala nokwakheka, izinhlelo zokuhamba kwamanzi okuphakanyisiweyo, ama-core barrels anobubanzi obuhlukahlukene obuphakathi kwebanga le-36mm kuya ku-152mm, kanye nezinhlelo zokuphatha i-wireline noma ama-rod ukuze kube nokukhuphukela kwemiphumela efanele. Izicelo zokuhlinzwa kwe-rotary core zikhula kwiimeko ezahlukene zomhlaba okuhlanganisa ucwaningo lokwenzeka kwezakhelo, ukuhlola amandla okuthwala, ukuqagela nokulungisa kwesimo, ukuhlola umhlaba ongozini, kanye nokuhlola izindawo ezinzima ezinomhlaba onetshe, amatshe amakhulu, noma ama-layer enziwe ziqinile eziphikisana nezindlela zokuhlanza ezijwayelekile. Le ndlela yokuhlola ibalulekile uma bonke bahlinza badinga ukuhlukanisa phakathi kwemibandela ehlukene yomhlaba, bakhomba izindawo ezinzima noma amatshe anokhozi, balinganise izinga lekhwalithi yamatshe ukuze kube nokufakelwa okujule wokuhlinza kwembobo, noma baqinisekise ukutholakala nokuthamba kwezigaba ezisemqoka ezinjengezibuko ze-sand ezinzima noma ama-gebedlayi enzelwe i-clay enezinga. Abakhi nabaqhubi bezinsiza bemikhiqizo ye-geotechnical bathembele ekutheni ukuhlinzwa kwe-rotary core kuqedeleze ukusaba kokwakhiwa kwezakhiwo, kwakha izikhathi ezinzulu zamapile nezimfanelo zokuthwala, nokunciphisa ubungozi bokwakha ngokunikeza ulwazi olunembile olungaphezulu kwendawo ngaphambi kokutshala imali enkulu emshinini wokwakha izisekelo ezijulile nokulungiselela izindawo.
