Izinsimbi Zensimbi

Izinsiza ze-bar ze-steel zimele into esemqoka yokuphakamisa kwi-sistimu yokuthola umhlabathi, zisebenza njengeyona ndawo ephakeme yokuthwalwa kumathafa alungisiwe. Lezi zinsiza eziyinkehli zifika ngesikhumba esiqinile, ngokuvamile phakathi kuka-16 no-32 mm ububanzi, ezifakwa ezikhungweni ezibhakabhakayo ezakhiwe ngaphambi kokufakwa futhi ziqiniswa nge-grouting ukuze kudaleke isakhiwo somhlabathi esiqinile, esiqinile. Ngokuphathelene nokwakhiwa kwemikhakha emikhulu kanye nokulungiswa komhlaba, izinsiza ze-bar ze-steel zinikeza ukwesekwa kwezakhiwo okubalulekile kumawindi okugcina ngesikhathi esisodwa nangokuphakade, ukuvikelwa kwemikhawulo, kanye nokuxhaswa kokukhishwa emhlabeni. Inqubo yokufaka ihlanganisa ukuhlinzwa izikhala emhlabathini okukhona noma kumaroka, ukufaka ibha ye-steel, nokugcwalisa isikhala esingaphakathi nge-grout ukuze kuqinisekiswe ubudlelwano obuphelele phakathi kwesikhumba nesimo esizungezile, kudala izinto ezihlanganisiwe ezinomthamo ophakeme wokuqina kokujula nokuqiniswa kokukhipha. Izicelo ze-bar ze-steel zikhula ezinhlelweni ezahlukahlukene ze-geotechnical kufaka phakathi ukuqiniswa kwezinyathelo ezikhethiwe, ukukwazi kwezinsiza, ukuvikelwa kwezindawo zokungena kumathunhu, kanye nokuxhaswa kokuhlinzwa komhlaba ezindaweni zokwakha zamadolobha. Lezi zinsiza zokukhuhla zisebenza kahle kakhulu ezimbonini ezihlaselisayo, emhlabeni osele, nasezindaweni zempilo lapho izindlela ezijwayelekile zokushayela i-pile noma izindlela zokwakha ezijulile zingase zingabi yinhle, noma zingabe zisezingeni eliphakeme. Ubuchwepheshe bokuhlanza umhlaba busebenzisa amandla angaphakathi okuphuka komhlaba kanti ibha ye-steel inikeza ukuqiniswa okwengeziwe, kudala isakhiwo somhlaba esizinzile ngokwezimoto esingakwazi ukumelana nezinsiza ezinkulu zomoya nezikhathi zokusabalala. Abakhi basebenzisa izinsiza ze-bar ze-steel uma behlangabezana nezimo zomhlaba eziguquguqukayo, indawo encane, noma izigaba zokwakha lapho ukuhlela nokufaka ngokushesha kuyizimfuneko ezibalulekile zokusebenza. Ukukhethwa kwemishini kanye nezindlela zokufaka kunomthelela omkhulu ekusebenzeni kwe-system ye-bar ye-steel kumaphrojekthi ajulile. Imishini yokuhlanza kumele ikwazi ukukhiqiza izikhala ezihlanzekile, ezivundlile eziyindilinga, ngokuvamile kudinga imishini yokuhlinzwa ye-rotary noma ye-percussion efanele ukuhlukaniswa komhlaba noma kumaroka ahlangabezana. Izinsiza ze-grouting zicela ukunakekelwa okuphelele kontrol yomfutho, ukuhamba kwe-grout, nezikhathi zokuphila ukuze kuqinisekiswe ukuthuthukiswa okuhle kokubambisana phakathi kwesikhumba nezimo ezizungezile. Ukuklama kwezinhlelo ze-bar ze-steel kudinga ukuhlolwa okubanzi kwe-geotechnical, kufaka phakathi ukuvuselelwa komhlaba, ukuhlolwa kwamandla, kanye nokuhlola ukuvikeleka kwezingxenye ukuze kutholakale ukuhlela okufanele, ubude, kanye nomthwalo ophakeme. Okwakhiwa kumele kuqaphe izici ezifana nezinga le-tabling, ukuhlanganiswa komhlaba, i-friction angle, kanye nomthelela wesimo sezulu isikhathi eside lapho kucaciswa ubukhulu bokubamba nezindlela zokufaka, kuqinisekisa ukuthi uhlelo oluqinisiwe luhlala luphakeme njalo ngezikhathi zokuphakela isakhiwo esisekelayo.
