Iphuli eliphindwe kabili lokuhlanganiswa komhlabathi ophakeme

I-Double rotary deep soil mixing iyindlela ethuthukisiwe yokuthuthukisa umhlaba engena emoyeni, esetshenziswa ama-augers aphindwe kabili noma aguquguqukayo ukuze ifinyelele ekujoliseni okujulile komhlaba nezingxube zokubopha ezijule phakathi kuka-5 no-40 amagumbi. Le ndlela yokwakha isiseko ikhethekile ihlanganisa ukuxuba kwemishini kanye nokuzinza kemikhosi, idala amakholomu omhlaba afanayo anokuthuthukiswa okuphawulekayo kokuphathwa kwemithwalo kanye nezici zokuhlala ezincishisiwe. Le nqubo ibandakanya ukufaka ama-shaft aphindwe kabili emhlabeni, lapho i-shaft ngalinye ijikeleza ngejubane elilawulwayo nezindlela ukuze kuhlanganiswe umhlaba wendabuko nezixube zokubopha, izengezo, noma izinto zokugxila. Lokhu kuhlanganiswa kahle kukha amakholomu azinzile, aphathekayo, asebenzela indlela yokusekela izakhiwo ezidinga ukubambelela okwenyukayo ezimnandi zezimo zokwakhiwa. Le ndlela ikakhulukazi iyasebenza emathwamini, i-silts, i-peats, nasezingxenyeni zomhlaba ezihlukahlukene lapho izindlela zendabuko zokushaya okwakhiwe noma zokuwela umhlaba zingaba nezehlakalo ezithile noma zingabi nezindleko. Imishini yokuxuba ye-double rotary deep soil mixing ivame ukuba nezinhlelo ze-hydraulic ezikwazi ukukhiqiza torque ephezulu ngenkathi zigcina ukulawula ubude ngendlela enembile nolayini lokujikeleza. Uhlelo lokujikeleza kanti luqinisekisa ukuhamba komhlaba okuphezulu nokuhlanganiswa okujwayelekile nezinto zokubopha, kuholela kumakholomu anemisebenzi yezobunjiniyela efanayo kuyo yonke ubude bawo. Izincazelo zomshini zihluka ngokuya ngezidingo zephrojekthi, ngezakhiwo zokuxuba ezizungeze phakathi kuka-0.5 no-2.5 amamitha, kuvumela abacwaningi ukuba bakhe izixazululo zokuthuthukisa umhlaba ezihlukene. Le ndlela ithatha izithombe zomhlaba ezihlukahlukene futhi ingafaka ama-agent ahlukanisayo ahlukahlukene kufaka phakathi i-Portland cement, i-lime, i-slag, kanye nezixube ezikhethekile, ilingana nezimo ezithile zokwakhiwa kwe-geotechnical nezinhlelo zokusebenza ezimisiwe ngesikhathi sokwakha. Izicelo ze-double rotary deep soil mixing zifaka phakathi izimboni eziningi zokwakha, ukusuka kumaphrojekthi amakhulu ezinsiza ezifana nokwakha okukhangisa nezokwakha ezimbonini. Le ndlela ibalulekile ekwakheni izinqubo zokuphakamisa, ukunciphisa i-liquefaction, kanye nokusekela izakhiwo ezingaphansi komhlaba, ikakhulukazi lapho ukujikeleza komhlaba okuphansi kanye nomthelela omncane wemvelo kubalulekile. Ezindaweni zasemadolobheni ezinokwakhiwa okubalulekile eduze, i-double rotary mixing inikezela ngenketho ethulile kunezindlela zokushaya eziphoqayo ngenkathi igcina izikhawu zokwakha ezisheshayo. Amakholomu omhlaba athuthukisiwe ahlinzeka ngama-akhawunti amahle wokuhleleka kwemithwalo, ukunciphisa ukuhamba okunezinhlelo, kanye nokuthuthukiswa kokumelana kwemithwalo yokujikeleza kwama-building, amabhuloho, nezinhlelo ze-offshore. Kuzicelo zezimboni zasemanzini nasezikhungweni zokuthuthukiswa kwe-waterfront, ukufaniswa kwalesi siphakamiso nezindawo zamanzi asawoti kanye namandla okusebenza ngaphansi kwezimo zejilimi lomhlaba kubenza kube isixazululo esikhethwe sokwakha. Amakholomu wokuxuba umhlaba angaklanywa njengezinto eziphindaphindiwe, amaqembu asekelayo imithwalo emikhulu, noma odonga oluqhubekayo lokugcina, kunikeza abacwaningi izilungiselelo eziguquguqukayo zokwakha ezihambisana nezinselelo ze-geotechnical zomphakathi nezidingo zokwakhiwa.
