Amarodi Wokubhoboza Amaphiko

Amarhodu we-shell-type azinzile izinto ezibalulekile zohlelo lokuwela kwezakhiwo ezisetshenziswa ezinhlelweni zokwakha izisekelo ezijulile nezobunjiniyela bendawo. Lezi zikhala ezikhethekile zisetshenziswa njengendlela eyinhloko yokwandisa izimbobo ezihambelana nezendlovu ezahlukene nasenkululekeni yokufaka ama-pile. Ezenzweni zokufaka ama-pile, amarhodu we-shell-type asebenza ngokujikijela naku-methods yokushaya, athuthumela kancane phansi, futhi acindezela impahla engaphakathi. Imithetho enembile yamarhodu ivumela ukuqhubeka kokukhipha umhlaba ophakanyisiwe ngaphakathi, ivumela abakhi ukuba bahlola izimo zomhlaba, baphawule i-composition yomhlabathi, futhi bahlonze ukujula kwezingqimba zokuxhasa. Amarhodu we-shell-type asiza kabi emhlabeni ogcwele, emivundlweni yensila, nasezindaweni ezihlanganisa umhlaba nethafa lapho okukhona uk drilling kwe-open-hole kungahambisani kahle noma kungungcono kwezoqoqosho. Inqubo ejwayelekile yokufaka ama-pile okuphumayo esebenzisa amarhodu we-shell-type ibandakanya ukujikeleza noma ukushaya i-tubular casing emhlabeni ngasikhathi sinye ukwakha impahla yokuphuma. Njengoba amarhodu anqamulisa, ahlisa umhlaba ngasohlangothini, enza iprofayili yempahla ecindezelwe, edalweni lohlobo lwesikhumbuzo. Le pheni yokuphuma ibalulekile ukuze kuthuthukiswe ubukhulu bomhlaba nesikhumbuzo sokuphatha ezigabeni zomhlaba ezilula noma ezinzima, kuyenza ibe yisixazululo esihle sokwakhiwa kwezisekelo ezindaweni ezinomhlaba ongenampilo. Abasebenza ngemishini kumele baqaphe kahle isivinini sokudrill, i-torque yokucekela phansi, nezinga lokungena ukuze baphucule ukucindezelwa komhlaba futhi banciphise ukuphakama kwesurface. Izinhlelo zamahodula e-shell-type zanamuhla zixhumanisa ubuchwepheshe bokuhlola obuphambili kuhlanganise nama-sensors we-torque, izinkomba zokuqonda, kanye nezincwadi zokudrilla zesikhathi sangempela ukuze kuqinisekiswe ikhwalithi eqhubekayo ne-operations efinyelela kanjani emsebenzini wokufaka izisekelo eziyinqaba. Amarhodu we-shell-type athola ukusetyenziswa okukhulu ezinhlelweni zobunjiniyela ezidinga izisekelo ezithembekile eziyinqaba ezimweni ze-geological ezihlukene. Izicelo ezivamile zifaka phakathi ukwakhiwa kwe-pile ezimbotsheni, ubuchwepheshe bokufaka ama-screw pile, ukufakwa kwemicropile, kanye nocwaningo lobunjiniyela obukhethekile ezindaweni ezingcolile noma ezithintekayo emvelo lapho ukuhlinzekwa kwezimpahla zomhlaba kubaluleke kakhulu. Imishini inikezela kahle kumazinga aphazamisekileyo, okubandakanya i-bedrock eluphazamisekile, izendlalelo zomhlaba ezihlukahlukene, kanye nezindawo ezinezinga eliphezulu lamanzi aphansi. Ekuthuthukiseni ukwakhiwa kwemigwaqo, amarhodu we-shell-type anika izixazululo zokuwela ezilawulayo ezinciphisa ukunyakaza nokuphazamiseka kwenhliziyo uma kuqhathaniswa nezindlela zokufaka ezishayisayo. Abakhi balinga amarhodu we-shell-type ngenxa yokuba nekhono lokuzenzeka emizweni ehlukahlukene yokuhamba komhlaba, kusukela kumagciwane anemvula no-silt ama-deposits adinga ukuphathwa nempahla ye-pressure kuya kumafomu ama-granular anokusebenza okuqinile nezindlela ezincane ezihlanganiswe ne-cement. Idatha yokuhlola yomhlaba ethathwe ngesikhathi sokwandisa kwamarhodu we-shell-type inikeza ongoti bezobunjiniyela be-geotechnical ulwazi olukhulu lokuphucula ukwakhiwa kwezisekelo nokunciphisa ubungozi ezimweni ezinzima ezitholakale ezinhlelweni zokwakha ezinzima.
