Izinsiza zomhlabathi

Emkhakheni wokwakha izisekelo ezijulile kanye nezobunjiniyela bezomhlaba, ama-soil starters adlala indima ebalulekile njengenhloso ebalulekile kumkhakha we-segmental flight auger. Lezi zifakiwe ezikhethekile zenzelwe ukuhlinzeka ngephumelelo lokungena emhlabathini nokuqhumisa, kuvumela ukudala ama-boreholes kahle ezinhlelweni ezahlukene zomhlaba. Kungakhathaliseki ukuthi kwenzelwa amathuna ezisekelo, ukuthuthukiswa komhlaba, noma ukuhlela indawo, ama-soil starters ayizinto ezibalulekile ekuthuthukiseni izigaba zokuqala zomsebenzi wezisekelo ezijulile. Ukusebenza kwama-soil starters kuhlanganisa ukwakheka kwe-spiral flight okwenzela ukususa kahle umhlabathi njengoba i-auger ijikeleza. Le nguquko ayisiza kuphela ekungeni emhlabeni kodwa futhi inceda ukudlulisa nokususa izinto ezihlakazekile ezivela kwi-borehole. Ama-soil starters abalulekile ikakhulukazi ezimweni zomhlaba ezinzima, kufaka phakathi i-clay, i-silt, kanye ne-sand, lapho izindlela zokurhoxiswa zendabuko zingase zibe nezinkinga. Ngokuhlinzeka ngokuqhumisa okunembile nokulawulwayo, lezi zifakiwe zinciphisa ukuphazamiseka komhlabathi futhi zandisa ubumsulwa obuphelele bezisekelo ezisunguliwe. Izicelo eziyinhloko zama-soil starters zifaka ukufakwa kwama-drilled shafts, ama-bored piles, nezinye izinhlelo zokwakha ezijulile. Zisebenza kahle ikakhulukazi ezindaweni zokwakha zasemadolobheni lapho isikhala sinqunyelwe futhi kudingeka ukuthi kuthathwe ama-excavations anembile. Ngaphezu kwalokho, ama-soil starters asetshenziswa kakhulu ezihlolweni ze-geotechnical, lapho asiza ukusampula umhlaba ukuze kwenziwe ukuhlaziywa nokunquma izimo zesayithi ngaphambi kokwakhiwa. Le nqubo ayisize nje ekuhlelweni kwamaphrojekthi kodwa futhi iqinisekisa ukulandela izindinganiso zokuphepha nezomthetho. Uma ukhetha i-soil starter, kufanele kubhekwe izincazelo ezahlukene kanye nezici. Lokhu kufaka phakathi ububanzi be-auger, obuvamise ukuba phakathi kuka-6 kuya ku-36 inches, kanye nobude bezindiza, obungase buhlukane ngokuya ngedlulele lendawo edingekayo. Ukwengeza, impahla nokwakhiwa kwe-auger kubalulekile ukuze kuqinisekiswe ukumelana nokuqina nokusebenza ngaphansi kwezimo ezinzima. Ama-soil starters amaningi enziwe ngensimbi ephezulu ukuze akwazi ukumelana nezinselelo zokuxhumana ezijulile, futhi angase abe nezinsika ezinzima eziklanywe ukuze zibe nekhono lokusika elikahle. Ezinye izinkomba zokukhetha zifaka izidingo zamahora aphakeme ze-drilling rig ukuze kuqinisekiswe ukuhambisana ne-soil starter, kanye nohlobo lomhlaba nezimo ze-geological ezizobonwa ngesikhathi sephrojekthi. Ukuqonda izidingo ezithile zephephandaba, njengokudinga u-torque kanye namandla okuphakamisa, kungathonya kakhulu ukukhethwa kwe-soil starter. Kubathengisi nabachwepheshe abafuna ukwandisa amaphrojekthi abo ezisekelo ezijulile, ukutshalwa kwemali kuma-soil starters asezingeni eliphezulu kubalulekile. Kungakhathaliseki ukuthi uthenga noma uqashisa, lezi zithuluzi zibalulekile ekutholeni ukuqhumisa okuphumelelayo, ukuqinisekisa ubumsulwa obwakhiwe, nokwandisa ukusebenza kwezinhlelo zezisekelo ezimweni ezihlukahlukene ze-geotechnical. Ngokusebenzisa amandla ama-soil starters, ochwepheshe embonini bangathuthukisa ukusebenza kwabo kahle futhi baphawule ekuphumeleleni kokuphumelelwe kwama-phrojekthi akha izinkinga.
