Itekhnoloji ye-Glass fiber pultrusion ivula ixesha elitsha leBridges

Kutshanje, ibhulorho yohola wendlela ehlanganisiweyo iye yakhiwa ngempumelelo kufutshane neDuval, eWashington. Ibhulorho yenzelwe kwaye yenziwa phantsi kweliso leSebe lezothutho laseWashington State (WSDOT). Abasemagunyeni bancome le ndlela ingabiziyo kwaye izinzileyo kunokwakhiwa kwebhulorho yesintu.
Isakhiwo sebhulorho edibeneyo yeebhulorho ze-AIT, i-subsidiary yeteknoloji yeziseko ezingundoqo / i-AIT, yakhethwa kwibhulorho. Inkampani iphuhlise itekhnoloji ye-arch ehlanganisiweyo eyaphuhliswa liziko lezakhiwo eziphambili kunye nezixhobo zeYunivesithi yaseMaine zomkhosi, kwaye yaphuhlisa idekhi yebhulorho eyenziwe ngeglasi yeplastiki eyomeleziweyo enokubekwa kwi-arch yebhulorho.
Iibhulorho ze-AIT zivelisa ii-arches (iigarchi) kunye nefiber yeglasi eyomeleziweyo yeplasitiki (gdeck) kwisityalo sayo esiseMaine. Isiza sidinga kuphela indibano elula, egubungela idekhi yebhulorho kwi-arch yebhuloho, kwaye emva koko uyigcwalise ngekhonkrithi eqinisiweyo. Ukusukela ngo-2008, inkampani iqokelele izakhiwo zebhulorho eziyi-30, ubukhulu becala kunxweme olusempuma ye-United States.
Olunye uncedo lwezakhiwo zebhulorho edibeneyo bubomi babo obude kunye neendleko eziphantsi zomjikelo wobomi. Ngaphambi kokunikezelwa kwekhontrakthi ekhethekileyo kwiibhulorho ze-AIT, iSebe lezothutho laseWashington lihlolisise ngokucophelela yonke idatha yobunjineli malunga nokukwazi kweebhulorho ze-arch ezidibeneyo ukumelana nomlilo kunye nefuthe lezinto ezifana neenkuni ezidadayo. “Iinyikima nazo ziyinkxalabo,” utshilo uGaines. Le projekthi sisihlandlo sokuqala ndisazi ngokusebenzisa ibhulorho yearch ehlanganisiweyo kwindawo yenyikima yaseHighland, ngoko sifuna ukuqinisekisa ukuba iyahlangabezana neemfuno zoyilo lwenyikima. Saphosa imibuzo emininzi enzima kwibhulorho ye-AIT. Kodwa ekugqibeleni, baphendule yonke imibuzo yethu nganye nganye, kwaye sinokuqhubela phambili neprojekthi ngokuzithemba ngakumbi "
Iziphumo zibonisa ukuba iibhulorho ezidibeneyo zinokujongana nayo nayiphi na imeko eyingozi. “Sifumanise ukuba le bhulorho ikwazi ukumelana nenyikima kuneyona ndlela ikhoyo ngoku. Ulwakhiwo lwekhonkrithi elomeleleyo alunakuhamba lula kunye ne-seismic wave, ngelixa i-arch ethambileyo ehlanganisiweyo inokujinga kunye ne-seismic wave kwaye ibuyele kwindawo yayo yokuqala, ”utshilo uSweeney. Oku kungenxa yokuba kwisakhiwo sebhulorho edibeneyo, ukuqiniswa kwekhonkrithi kufakwe kumbhobho ongenanto, onokuthi ushukume kwaye ugxothwe kumbhobho ongenanto. Ukuze uqinise ngakumbi ibhuloho, i-AIT yomeleza i-anchor edibanisa i-arch bridge kunye nesiseko sekhonkrithi kunye ne-carbon fiber. ”
Ngempumelelo yeprojekthi, iSebe lezothutho laseWashington lihlaziye iinkcukacha zalo zebhulorho ukuvumela ukwakhiwa kweebhulorho ezidibeneyo. U-Sweeney ukwanethemba lokuba ungafumana izibonelelo ezininzi ezibonelelwa ziibhulorho ezihlanganisiweyo kwaye ukhuthaze usetyenziso oluqhubekayo lwezakhiwo zebhulorho edibeneyo kunxweme olusentshona. I-California iya kuba yinjongo elandelayo yokwandisa ibhuloho ye-AIT.
