Ithuluzi le-Walking Frame Multi-shaft power head rigs

Izinsiza zokwakha ezikwi-walking frame multi-shaft power head rigs zihloko ezikhethekile zokubhoboza eziklanyelwe ukwakha izakhiwo zokuphakamisa umhlabathi nokuqinisa umhlaba ezindaweni zokwakha ezifakazela ukuba nezinselele noma ezimfushane. Lezi zinsiza zixuba ikhono lokubhoboza okuqhubekayo nokuhamba kalula, kwenzele lokho kube yizinsiza ezibalulekile kumaphrojekthi okuqinisa umhlaba lapho imikhawulo yokuthi ungabeka kanjani noma izinhlelo zokusebenza zivikela ukufakwa kwezisindo ezinkulu zokubhoboza. Ekuhlinzekeni ngezisekelo ezijulile, ama-rigs we-walking frame multi-shaft asetshenziswa ikakhulu ekwakheni ama-diaphragm walls, ama-cutoff curtains, ama-secant kanye nama-tangent pile walls, kanye nezakhiwo zokuxuba umhlabathi. Indawo yazo eyinhloko ibandakanya izikhala ezijulile zasemadolobheni, ukwakha indlela yokudlula nokuhamba ngezithuthi, umsebenzi wesisekelo semigodi, kanye nokulungiswa kwezinsiza ezikhona lapho ukufinyelela kuvimbekile. I-configure ye-walking frame—eyisizinda esizishayelayo—ivumela i-rig ukuba ibhade ibe khulula endaweni, ibhake phakathi kwezikhala ngaphandle kokudinga izinsiza zokuhambisa ezihlukile noma amapande anzima. Le mobility ibaluleke kakhulu ezindaweni ezithuthukisiwe kakhulu lapho isikhala sendawo sibalulekile futhi izakhi ezizungezile zidinga ukuthi kukhishwe ukunyakaza okuncane nokwakha umsindo. Umthetho wezokusebenza wezinhlelo ezi-multi-shaft usebenzisa amathuluzi okubhoboza ahlakazekile noma ahlale ebhujiswa ngamadivayisi omgwaqo aphumelelisa amathuluzi ahlulekile afakwe esikhaleni esijwayelekile. Iphuzu ngalinye le-power head lilawulwa nge-hydraulic futhi lingasebenza ngokuzimela, livumela abaphathi ukuthi benze ukubhoboza kwamaphaneli okubeka phambili ngokwehla kwesikhathi sokuphindaphinda. Le mekhani esebenzisa iminyango ye-hydraulic noma izinhlelo zokuhambisa ikhulisa i-rig yonke kancane emuva kushintsho kwembobo esisha uma ipaneli iphelile. Ukubhoboza kuqhubeka kusetshenziswa ama-continuous flight augers, amathuluzi e-Kelly, noma izindlela zokuhamba ze-casing, kuya ngohlobo lomhlabathi nezincazelo zomsebenzi. Ukuhamba kwe-multi-shaft ngasikhathi sinye kwehlisa izikhathi zokuphinda ngomsebenzi ophakathi kwe-30-50% uma kuqhathaniswa nezinhlelo zeshafthi eyodwa, kwandisa kakhulu umnotho wephrojekthi kumagolo amakhulu okuqinisa umhlaba. Lezi zinsiza zifaka ama-rigs anezinhlaka ezijwayelekile zeshafthi ziqhubekela phambili ku-600 kuya ku-1500 mm, enezindonga zokubhoboza ezifika ku-50 kuya ku-70 imitha. Ukuhlola kuhlanganisa uhlobo lwe-twin-shaft (izikhala ezimbili ezibhoboza ngokuhlanganyela) kanye nezinhlelo ze-triple-shaft (izikhala ezintathu ezizimele). Izinsiza zesimanje zihlala zineziqondiso ezibambisene ze-hydraulic, ukulandelela izinduku, kanye nezinhlelo zokulawula ukujula ezizenzakalelayo. Izinhlelo zokuhambisa i-slurry zihlala zifakwe ngqo ku-rig frame, kuvumela ukuphathwa kwe-bentonite noma i-polymer slurry ngesikhathi sangempela ngaphandle kwezinsizakusebenza ezilandelayo. Izimfanelo zokukhetha ama-walking frame multi-shaft rigs ziqinisa izidingo zokubhoboza ukujula, ukuhlukaniswa komhlabathi, ububanzi nesikhathi sewandla, ukufinyelela endaweni, kanye nezinsuku zomsebenzi. Ipharamitha yamakhetha eyinhloko ibandakanya ukubaluleka kokuhlanganiswa kwezinkomba (kufanele kuhambisane nezincazelo zewal), umphumela omncinci we-torque (okutholwa ngephuzu lokuthwala umhlabathi nezidingo ze-cementation), ikhono lokuhambisa i-slurry, nezinhlelo zokuhambisa. Abakwa-contractors bahlola izimo zomhlaba—ikakhulukazi ukuvuvukala nokpressure yamanzi—ukuhlola izinga lokuguga kumathuluzi okucheza nokuba nezinye izinkinga. Izindinganiso eziwusemthethweni ezilawula lezi zinhlelo zifaka i-EN 12716 (ukuphepha kwezinsiza zokuphoqa), i-ISO 10937 (amagama ezinsiza zokubhoboza), kanye ne-DIN 4120 (ukukhuphuka kuzo izimpande eziyingozi). Imihlahlandlela ye-European CWA neziqhathaniso zomthetho wezokwakha ziphakathi kwezi zindinganiso ukuze zikhombise izimo zokusebenza nezokuphepha. Ukwamukelwa kwezesekeli ngaphansi kwe-ISO 14119 (ikhephe nemigomo eyahlukeneyo) kuyadingeka ezimakethe ze-EU.
