Ama-Auger

Ama-augers ari amathuluzi abalulekile okuthuthukisa adlalwa kakhulu emiphakathini yokwakha i-deep foundation kanye ne-geotechnical engineering. Lezi zinto ezikwenziwe ngesimo se-spiral zenzelwe ukuhamba umhlabathi, itshe, nezinye izinto, zenza kube yisigaba esibalulekile ekwakhiweni kwezinhlaka, ama-piers, nezinye izakhiwo ezingaphansi komhlabathi. I-auger isebenza ngesimiso esilula kodwa esisebenza kahle: njengoba i-helical screw ejikelezayo ingena emhlabeni, ishintsha okwakhiwa futhi ilethe phezulu ukuze ikhishwe. Le nqubo isebenza kahle futhi inciphisa ukuphazamiseka komhlabathi okumnandi, okubalulekile ezinhlelweni ze-geotechnical ezithintekayo. Emaphakathini e-deep foundation, ama-augers avamise ukusetshenziswa ukuze ahluke izimbobo ezinobukhulu obukhulu ezidingekayo kuma-piles, ama-caissons, nezinye izisekelo ezijulile. Kuhle ezihlinzekweni ezifana nokuhlola umhlabathi, ukuthuthukiswa komhlaba, kanye nokufakwa kwama-anchors. Ngokwezidingo ezithile zephrojekthi, ama-augers angaguqulwa ukuze ahehele izinhlobo ezahlukene zomhlabathi, kuhlanganise ne-clay ethambile, igalofu, ne-soil eqinisiwe, okwenza kube amathuluzi aphumelelayo emathuthumeni e-geotechnical. Ngaphezu kwalokho, angasebenza ngokuhlanganyela nezinye izindlela zokuhlola, njengokukhuliswa kwezinsiza zokubhola okanye izindlela ze-continuous flight auger (CFA), ukuze kuthuthukiswe ukusebenza kahle nokunembile. Izincazelo ezijwayelekile zama-augers zihluka ngokuya ngokuqondiswa kwazo kanye nezimo zesiza. Ama-augers ajwayelekile angahluka nobubanzi ukusuka kumayinki angu-6 kuya phezulu kwama-36, ngezikhathi ezingeni ezingaphezu kwama-100 amasonto. Ukuqanjwa kwematerial ye-augers kubalulekile; insimbi eqinile ivamise ukusetshenziswa ukuze iqinisekiswe ukuguga kanye nokumelana nokugqotshwa, kanti izakhamzimba ezikhethekile zingasetshenziswa ukuze kuthuthukiswe ukuqina ezimeni zomhlabathi ezinamadolo. Ama-augers angabekwa nezinhlobo ezahlukene zokuhamba, ezifana nezindiza ezilodwa noma ezimbili, ukuze kuthuthukiswe ukususa okwakhiwa nokunciphisa ukufaka ngaphandle kokusebenza. Uma ukhetha i-auger yephrojekthi, izimfuneko ezimbalwa kumele zicatshangelwe. Okokuqala, kubalulekile ukuhlola uhlobo lomhlabathi nezimo ze-joloji endaweni, njengoba lokhu kuzothinta ukwakheka nokubanzi kwe-auger. Ngaphezu kwalokho, ukujula kanye nobubanzi bezimbobo ezidingekayo kuzobamba isikhala nobukhulu be-auger obudingekayo. Iphrojekthi edinga ukuhlinzeka okuphezulu ingase ibheke ama-augers anobubanzi obukhulu noma lezo ezikhethekile eziklanyelwe ukushesha. Ngaphezu kwalokho, ukuhambisana neekhamera nemishini yokubhola akukhona okubalulekile, njengoba ama-augers kufanele ahlale echwephesha kuzo zonke izilungiselelo zokubhola. Ekupheleni, ama-augers adlalisa indima ebaluleke kakhulu ekwakheni i-deep foundation nase-geotechnical construction. Ikhono labo lokungena kahle ezinhlelweni ezihlukahlukene zomhlabathi nokunciphisa ukuphazamiseka kubenza babe nezisombululo ezinethuba elikhulu kokuhlinzeka. Ngokwazi izincazelo nezimfuneko zokukhetha lawa mathuluzi, abathengisi nabaklami bangakwazi ukuqinisekisa ukusebenza kahle nokuphumelela kwephrojekthi. Noma ethengwe noma eqashiswayo, i-auger efanele ingaba nomthelela omkhulu ekusebenzeni kahle nasekuqhubekeni komsebenzi wezisekelo ezijulile, ngokuqhubekela phambili ekwakheni amandla azinzile emikhakheni yokwakha.
