Ama-Flange Okufaka

I-flange ye-casing iyizixhumanisi ezibalulekile zokwakha kanye nezithako zokweseka eziyinxalenye ebalulekile ye-soil nailing kanye nezinhlelo ze-casing string ezisetshenziswa emsebenzini wesisekelo esijulile nasekuqineni komhlaba. Lezi zixhumanisi ze-metali ezihlinzekiwe, ezivamise ukwenza nge-asteel enamandla, zisebenzisa ukuthunga izingxenye ze-tube ye-casing ezilandelanayo ngenkathi ziqhuba imithwalo futhi zigcina ukuhlela kuyo yonke ubukhulu obufakiwe. Emishinini ye-soil nailing, ama-flange e-casing asebenza njengamaqembu oxhumano phakathi kwezicucu ze-casing, akha i-casing string eyodwa futhi eyakhiwe kahle engakwazi ukumelana nezimo zokpressure ezikhaliphile, imithwalo yokungqubuzana, kanye nemithwalo engama-vertical eyenziwe yimihlahlandlela yomhlaba nezakhiwo zezakhi. Umklamo we-flange uvame ukufaka izikhala eziningi ze-bolt ukuze uqinisekise ukuhanjiswa kwezingxenye, ukuxhumana okufakwe noma okuboshwe emzimbeni we-casing, nezindawo zokuphatha ezikhuphukayo ezidlulisa imithwalo kahle kumachune adlulelayo. Lezi zixhumanisi zibalulekile lapho usebenza ngezimo ze-geotechnical ezinzima, kubandakanya umhlaba ongazinzile, amazone aphakeme emanzini, nezikhala eziphansi ezidinga ukwesekwa okuqhubekayo kwe-casing ukuze kwenziwe imikhakha ingabi khona nokwenza kube nesikhala sokuphepha kwabasebenzi ngesikhathi sokuhamba nokufaka. Ukukhetha nokuchaza ama-flange e-casing kuphathelene nezinto eziningi ezifaka phakathi imithwalo yomhlaba elindelekile, ukuhlukaniswa komhlaba, ububanzi bokufaka, kanye nendlela ethile yokuhlanza umhlaba esetshenziswayo. Izimo zomhlaba ezithambile ezifana ne-clay, i-silt, ne-sand ethambile zivame ukudinga izinhlelo zezithombe ezinzima ezine-flanges eziqinisekisa ukuthwala imithwalo emikhulu ye-radial nokugcina ubuqiniso bokwakha ngezikhathi ezinde. Ngokuphambene, izicelo ezihlanganisa umhlaba ophumuliwe noma omisiwe zingasebenzisa ukwakheka kwe-flange okukh light. Ubuningi be-flange, ububanzi bemidwebo, nezikhala ze-bolt kuyavumelekile ukuze kuqinisekiswe ukuhambisana nezinsiza zokubhola ezijikayo, imishini yokutshala, kanye nemishini ye-soil nailing ethize ejwayelekile ezindaweni zokwakha. Ama-flanges kufanele abonise imithwalo ye-vertical evela emithwalweni ye-casing string kanye nezimo ezijiyile ezivelelayo, okwenza ukukhiqizwa kwephrojekthi nokulawula ikhwalithi kubaluleke kakhulu ngesikhathi sokukhiqizwa. Ukufakwa kwe-flange ye-casing kuvame ukwenza amaqembu okwakha anekhono nezinkontileka zokubhola ezijwayele ukubonisana nezinyathelo ze-soil nailing kanye nezikhungo zokwakha ezijulile. Ukuhlinzwa kahle kwe-bolts ye-flange ukuze kube namandla athile kuqinisekisa ukusabalalisa imithwalo futhi kugweme ukuphuthuma ngesikhathi sokuhamba okulandelayo noma uma kubhekwa imithwalo yomhlaba. Ama-flange e-casing asetshenziswa ezinhlelweni ezahlukene zokwakha, kufaka phakathi ukufakwa kwamasakhiwo akhona, ukwesekwa kokumba ezindaweni zasemadolobheni, ukuqinisa izikhukhula, kanye nokwakha izinhlelo ze-soldier pile ne-lagging emisebenzini yesikhathi eside nangesikhathi esifushane. Ukuhlala kanye nokumelana nokubola kwalokhu kuhlaziywa kuyizinto ezibalulekile, ikakhulukazi ezindaweni zasolwandle noma ezindaweni ezinomoya ophakeme wamanzi. Izinhlelo zendawo zamaflange modern zakhiwe ukuze zihlanganise nezinsiza zokuhlola nezicell umthwalo ezivumela ukuhlolwa kwesikhathi sangempela kwemithwalo yokukhukhula kanye nokusebenza kwezakhiwo kuyo yonke imisebenzi yokwakha.
