Ubuchwepheshe be-Glass fibre pultrusion buvula inkathi entsha yamaBhuloho

Muva nje, ibhuloho elinguthelawayeka eliyinhlanganisela lakhiwe ngempumelelo eduze kwaseDuval, eWashington. Ibhuloho laklanywa futhi lakhiqizwa ngaphansi kokuqondisa koMnyango Wezokuthutha waseWashington State (WSDOT). Iziphathimandla zancoma le ndlela engabizi kakhulu futhi esimeme kunokwakhiwa kwamabhuloho esintu.
Isakhiwo sebhuloho esiyinhlanganisela samabhuloho e-AIT, inkampani ephethwe yi-Advanced Infrastructure Technology / AIT, ikhethelwe ibhuloho. Le nkampani ithuthukise ubuchwepheshe obuhlanganisiwe be-arch eyasungulwa isikhungo sezakhiwo ezithuthukisiwe nezinhlanganisela ze-University of Maine yezempi, futhi yathuthukisa ideskithophu yebhuloho elenziwe ngepulasitiki eqinisiwe ye-glass fiber engabekwa phezu kwe-arch yebhuloho.
Amabhuloho e-AIT akhiqiza ama-arch tubular angenalutho (ama-garches) kanye ne-glass fibre reinforced plastic deck (gdeck) esitshalweni sayo e-brewer, eMaine. Isayithi lidinga kuphela ukuhlanganiswa okulula, ukumboza ideskithophu yebhuloho ku-arch yebhuloho, bese uyigcwalisa ngokhonkolo oqinisiwe. Kusukela ngo-2008, inkampani ihlanganise izakhiwo zebhuloho eziyinhlanganisela ezingama-30, ikakhulukazi ogwini olusempumalanga ye-United States.
Enye inzuzo yezakhiwo zebhuloho eziyinhlanganisela impilo yazo ende kanye nezindleko eziphansi zomjikelezo wempilo. Ngaphambi kokunikeza inkontileka ekhethekile yamabhuloho e-AIT, uMnyango Wezokuthutha waseWashington State ubuyekeze ngokucophelela yonke idatha yobunjiniyela mayelana nekhono lamabhuloho ayinhlanganisela alwa nomlilo kanye nomthelela wezinto ezifana nokhuni oluntantayo. "Ukuzamazama komhlaba nakho kuyakhathaza," kusho uGaines. Le phrojekthi ngiyaqala ukwazi ukusebenzisa ibhuloho eliyinhlanganisela ye-arch endaweni yokuzamazama komhlaba e-Highland, ngakho-ke sifuna ukuqinisekisa ukuthi ihlangabezana nezidingo zomklamo wokuzamazama komhlaba. Saphonsa imibuzo eminingi enzima ebhulohweni le-AIT. Kodwa ekugcineni, baphendule yonke imibuzo yethu ngamunye ngamunye, futhi singaqhubekela phambili nomsebenzi ngokuzethemba okwengeziwe“
Imiphumela ibonisa ukuthi amabhuloho ayinhlanganisela angabhekana cishe nanoma yisiphi isimo esiyingozi. “Sithole ukuthi leli bhuloho liyakwazi ukumelana nokuzamazama komhlaba kunesakhiwo esikhona njengamanje. Isakhiwo sikakhonkolo esiqinile asikwazi ukunyakaza kalula negagasi lokuzamazama komhlaba, kuyilapho i-arch eyinhlanganisela eguquguqukayo ikwazi ukushwibeka ngegagasi lokuzamazama komhlaba bese ibuyela endaweni yayo yasekuqaleni,” kusho uSweeney. Lokhu kungenxa yokuthi esakhiweni sebhuloho eliyinhlanganisela, ukuqinisa kukakhonkolo kufakwe epayipini elingenalutho, elinganyakaza futhi livalwe epayipini elingenalutho. Ukuze kuqhutshekwe nokuqinisa ibhuloho, i-AIT iqinise ihange elixhuma i-arch yebhuloho kanye nesisekelo sikakhonkolo nge-carbon fiber. ”
Ngokuphumelela kwephrojekthi, uMnyango Wezokuthutha waseWashington State ubuyekeze imininingwane yebhuloho ukuze uvumele ukwakhiwa kwamabhuloho ayinhlanganisela eyengeziwe. U-Sweeney uthemba futhi ukuthi ungathola izinzuzo eziningi ezinikezwa amabhuloho ayinhlanganisela futhi ukhuthaze ukusetshenziswa okuqhubekayo kwezakhiwo zebhuloho eliyinhlanganisela ogwini olusentshonalanga. I-California izoba umgomo olandelayo wokunweba webhuloho le-AIT.
