Izinsiza zokuhamba ze-CSM

Izixhumi ezihambayo ze-CSM ziwumgogodla wezobunjiniyela be-Cutter Soil Mixing, indlela ekhethekile yokumba ngokujulile nokuzinzisa umhlaba ebaluleke kakhulu ekwakhiweni kwezobunjiniyela be-geotechnical yanamuhla. Lezi zinhlelo zokuthwala zisekela ikhanda lesikala le-CSM ngesikhathi sokuhluza, ukuhlanganisa, nokugcina izinqubo ezihambisanayo, kuvumela abakhiqizi ukuba benze odonga lwemidwebo oluhlangene lwezidingo eziphansi nezokungena kwamanzi, kanye nezithiyo zokubamba izinto eziyingozi ngokuqondile nangokuphumelelayo. Emsebenzini wokwakha izisekelo ez deep, izixhumi ezihambayo zikwazi ukuhlinzeka ngokwakhiwa kwezithiyo ezingenamanzi, izithiyo zokubamba imfucumfucu, kanye nezindonga zomzimba ezisetshenziswa ngokuhambisana nezinhlelo ze-secant pile, odongeni lwe-sheet pile, kanye nezicelo zokugrouta kwe-jet. Izixhumi ezihambayo zisebenza njengemishini ethathwa noma efakwe kumakharavani eportal, eziqukethwe ikhanda le-CSM ezindaweni eziyiqondile futhi zikhulise ngokujulile ezicini ezihlongozwayo. Umqondo wokusebenza uhilela ikhanda lesikala elihambayo elihlinzeka ukupenda komhlaba ngasikhathi sinye lokukhwaza izinto zokubopha—okujwayelekile ukuba ama-slurries anomhlanga noma izinto zokubopha ezithile—kuqinisekisa ukuhlanganiswa okulinganayo kuzo zonke ububanzi bodonga. Isakhiwo sigcina uzinzo oluphakathi noshintsho oluphezulu phakathi komjikelezo wokuhluza, okungase kwande kube ubude obungama-60+ amamitha kuye ngezinyathelo zomshini nezimo zomhlaba. Umsebenzi wokuhamba, ophathwa ngezinhlelo ze-hydraulic noma ze-diesel-electric, uvumela isakhiwo ukuba siqhubeke sithuthuka edolobheni lokusebenza ngochungechunge lwezinyathelo ezihambelanayo, kudala odonga ahlukaniswe kahle akhiwe endaweni yokwakheka, ububanzi obuvamile phakathi kuka-0.4 kuya ku-2.5 amamitha. Le nqubo ibiphumeza kakhulu kunemishini ejwayelekile yokwakha odonga futhi ikhiqiza izimpahla ezincane kakhulu ezidinga ukususa. Lo mkhakha ufaka izinhlelo ezihlukahlukene zokwakha ezivumelana nezimo ezahlukahlukene zomhlaba nezidingo zephrojekthi. Izinsiza ezinkulu ezivumelanayo zikhola ezinhlelweni zemboni, ziphakamisa izikhanda zokuhluza ezifika ku-3.5 amamitha ububanzi futhi zikhokhela ubukhulu obuphakeme kuka-80 amamitha. Izinsiza ezincane ezihamba obala zivumelana nezindawo ezinamakhono kulezo ezikhawulelwe ukuphakama phezulu. Izinhlelo ezincane ezijikijelayo zikhulisa ukuhlinzeka kwezinsiza zephrojekthi ezinomhlaba omncane, ngenkathi ukwenza imiklamo engaguquki kuthuthukisa isu lokulawula emhlabeni oguquguqukayo nasezinkundleni eziphakeme. Izimfanelo zezimoto zikhombisa ububanzi bokuhluza obukhulu, ubukhulu bezokwakha obuphezulu, ikhono lokuhambisa isitsha, kanye nezinhlobo zezinzuzo ezahlukahlukene ezihambisana nesistimu. Ukukhethwa kwezixhumi ezihambayo ze-CSM kuya ngokusemthethweni ezimweni eziphansi, ububanzi obubalulekile bezindonga nezidingo zokungena, kanye nezidingo zezimo zokuhlela. Abakhiqizi bahlola ukusabalala komhlaba—ikakhulukazi ukufika kwsandla esiqinile, i-cobbles, noma amabulashana aqinile—njengoba lokhu kuthinta ngqo ukusebenza kokuhluza nezinkokhelo zokubopha. Izimo zamanzi omhlaba, izidingo zokulandelana kwezindonga, kanye nemikhawulo yokujula kuchaza uhlobo lwezixhumi nezimfanelo zezikhanda zokuhluza. Izilinganiso zokukhiqiza ziqoka izifundo zokuhlanganisa, izikhathi zokuhlanganisa ama-slurry, nezikhathi zokuhambisa ikhanda lesikala. Ukwakhiwa kwezimoto nokufinyelela endaweni yokusebenza kuhilela ukususa ukukhetha kwesixhumi, ikakhulukazi emhlabeni odinga ukuhlinzeka lapho izindlela zokufinyelela nezindawo zokusebenza zingase zibe nezingqinamba. Izindinganiso zamazwe okugunyaza izicelo ze-CSM zifaka i-EN 14199 yokuhlanza ngengcindezi kanye ne-EN 12715 ye-anchors ezihlanziwe, ngesikhathi izinhlelo zokuphepha kwemishini design zivikela i-EN 13001 yamakhana ahamba kakhulu nezikhombandlela ze-ISO ezifanele. Izindinganiso ze-DIN zesiJalimane zinikeza umhlahlandlela owengeziwe ekwakhiweni kwezinsiza zokuhluza nokusebenza kahle kokuhlanganisa umhlaba. Abakhiqizi baye basebenzisa izitifiketi zomkhiqizo wesithathu nezinhlelo zokusebenza zokuhlola ukuqinisa ubuqotho bendonga, ukuhlanganiswa kokubopha, nokuhambisana nezidingo zokuphatha namasayithi.
