I-Rimer Yedijithali Yezinsimbi

I-Cluster diameter reaming ibonisa umsebenzi wakho wokudoba ophucukileyo ngaphakathi kokusebenza kwe-DTH percussion drilling, lapho ama-hammer amaningi ahlanganyelwe asebenza ngasikhathi sinye ukuze wandise ezikhukhulweni ukuze zibe nezincazelo eziqondile zokwakhiwa kwemizi emidala. Le ndlela ibalulekile emisebenzini ye-geotechnical engineering edinga ukun准确馨li kwayo ngokwesimo nezinsizakalo ezisebenza kahle ekuphulweni kwezindonga ezinzima. I-cluster diameter reamer isebenza ngokusebenzisa amandla okuphurhumayo ahlanganiswe ngama-hammer amaningana axhunyiwe, aphumelelisa umphumela ophakathi ukuze athole ukwandiswa okujwayelekile nezindawo ezithambile. Le ndlela yokuhlanganyela ithuthukisa kakhulu ukusebenza kokudoba uma kuqhathaniswa nemisebenzi ye-hammer eyodwa, ikakhulukazi lapho kuhanjiswa ezindongeni ezithokozisayo, i-gravel ephumile, kanye nezingqimba eziqinile kakhulu ezitholakala emsebenzini wokwakha. Imodeli yokusebenza ye-cluster diameter reaming ibandakanya ukuhlela kahle kwezingwegwe ezikhukhulwene, ukujolisa ama-hammer, kanye nokukhuculula okuqhubekayo ukuze kukhishwe ama-cuttings futhi kulungise ukusebenza kwemishini ye-percussion. Abasebenza kufanele bakhe i-aphasi yomoya, izinga lokufaka amanzi, kanye nezinga lokujikeleza ukuze bakhuphule izinga lokudoba ngenkathi behlola ubuchwepheshe bokungena kweholi obumqoka kumaflanga e-pile shaft, ukuhlela izigubhu ze-pile eziphumile, kanye nokwakhiwa kwe-drilled caisson. Le nqubo iyahambisana nezindawo ezihlukahlukene zomhlaba, kusukela ezindaweni eziphukile zomhlaba ukuya ezisandleni nasezigubhu ezinzima, okwenza ibe yinto ebalulekile ezimweni eziyinkimbinkimbi zemvelo ezivamile emisebenzini enkulu yokwakha kanye nemizi lapho izinhlelo zomsebenzi zidinga amakhono athuthukile. Izicelo ze-cluster diameter reaming zifaka izingxenye ezahlukahlukene zezobunjiniyela be-civil kufaka phakathi izisekelo zezakhiwo eziphezulu, ukwakhiwa kwemigwaqo namabhuloho, izisekelo zamadamu amanzi, ukulungiselela ukudoba ama-pile asezindaweni eziyinkimbinkimbi, kanye nezinhlelo zokuhlola ze-geotechnical ezimweni ezithokozisayo. Le ndlela ikhethekile ikakhulukazi kumapile aphumelele osayizi abanzi, ukufaka izindonga ze-secant, kanye nokwakhiwa kwezindonga ze-diaphragm lapho ukuzinza komjobo nokwakheka kwemiphumela okukhulu kungathinta ngqo ukuthuthukiswa komsebenzi kanye nokusebenza kwesakhiwo. Ukuhlela imishini kuvumela ukulungiswa kwezemvelo ezihlukahlukene, kuvimba abaqhubi ukuthi bahlule izikhukhulwane ezivela kumashwa amancane kuya kumashwa amakhulu ngokuya ngezidingo zokwakha kanye nokuziphatha komhlaba. Izinhlelo ze-cluster hammer ezithuthukisiwe zinikeza amandla okugcina, okuvumela ukuhlola izimo zomhlaba, ukuphumeza amandla okuphakamisa, kanye nezimo zokusebenza ezithinta izinqumo ezithathwayo ngaphakathi kokuhamba kwesikhathi. Ukukhetha ama-cluster diameter reamers afanele kudinga ukubheka ngokucophelela ukuhlukaniswa komhlaba, izidingo zokujula, amandla okwakhiwa okuhlosiwe, amandla atholakalayo, kanye nezikhawu zokuhlela zephrojekthi. Abahlinzeki bemishini abanolwazi banikeza ama-cluster systems ahlanganisiwe nezixhumi ezihlanganisiwe, ukuhlela ama-hammer okuqonda, kanye nosizo lobuchwepheshe obuphumelelayo ukuze kuqinisekiswe ukusebenza okuhle ezimweni ze-geotechnical ezihlukahlukene. Ukutshalwa kwezimali kumishini ye-percussion drilling yekhwalithi kanye nokuqonda kwabasebenzi abanamakhono kubaluleke kakhulu empumelelweni yephrojekthi, ikakhulukazi ezindaweni ezingathandeki nezidingo zokwakha ezihlukile ezihambisana nezindinganiso zokwakha zanamuhla.
