Girazi fiber pultrusion tekinoroji inovhura nguva nyowani yeBridges

Munguva pfupi yapfuura, bhiriji remugwagwa mukuru rakagadzirwa zvakabudirira pedyo neDuval, Washington. Zambuko iri rakagadzirwa uye rakagadzirwa richitungamirwa neWashington State Department of Transportation (WSDOT). Vakuru vakarumbidza nzira iyi isingadhuri uye isingadhuri pane kuvaka mabhiriji echinyakare.
Iyo inosanganiswa bhiriji chimiro cheAIT mabhiriji, inotsigira yepamberi tekinoroji tekinoroji / AIT, yakasarudzwa bhiriji. Iyo kambani yakagadzira iyo composite arch tekinoroji yakatanga kugadzirwa nepakati pezvivakwa zvepamberi uye macomposites eYunivhesiti yeMaine yemauto, uye zvakare yakagadzira dhizaini rebhiriji rakagadzirwa negirazi fiber yakasimbiswa plastiki inogona kuiswa pabhiriji arch.
AIT mabhiriji anogadzira maburi tubular arches (magarches) uye girazi fiber yakasimbiswa epurasitiki dhizaini (gdeck) pachirimwa chayo mubiki, Maine. Iyo saiti inongoda kuungana kwakapfava, kuvhara dhizaini yebhiriji pabhiriji arch, uyezve kuizadza nekongiri yakasimbiswa. Kubva 2008, kambani yakaunganidza 30 akaumbwa mabhiriji zvimiro, kunyanya kumahombekombe ekumabvazuva kweUnited States.
Imwe bhenefiti yezvakasanganiswa mabhiriji zvimiro hupenyu hwavo hwakareba uye yakaderera yehupenyu kutenderera mutengo. Vasati vapa kondirakiti yakasarudzika kumabhiriji eAIT, Washington State Department of transportation yakanyatsoongorora zvese zveinjiniya data pamusoro pekugona kwecomposite arch mabhiriji kuramba moto uye kukanganisa kwezvinhu zvakaita sehuni dzinoyangarara. "Kudengenyeka kwenyika kunonetsawo," akadaro Gaines. Ichi chirongwa ndekekutanga kuziva nezvekushandisa composite arch bhiriji munzvimbo yeHighland yekudengenyeka kwenyika, saka tinoda kuona kuti inosangana nezvinodiwa zvekutemesa kwemhepo. Takakanda mibvunzo yakawanda yakaoma kuAIT bhiriji. Asi pakupedzisira, vakapindura mibvunzo yedu yese mumwe nemumwe, uye isu taigona kuenderera mberi neprojekiti tiine chivimbo chakanyanya"
Mhedzisiro yacho inoratidza kuti mabhiriji akaumbwa anogona kubata nechero mamiriro ane ngozi. “Takaona kuti zambuko racho rinokwanisa kurwisana nekudengenyeka kwepasi kudarika maitiro echinyakare. Iyo yakasimba kongiri chimiro hachigone kufamba nyore neiyo seismic wave, nepo inochinjika inoumbwa arch inogona kuzungunuka ne seismic wave yobva yadzokera panzvimbo yayo yepakutanga," Sweeney akadaro. Izvi zvinodaro nekuti mune inoumbwa bhiriji chimiro, iyo kongiri yekusimbisa inoiswa mugomba pombi, iyo inogona kufamba uye kuvharwa mugomba pombi. Kuti uwedzere kusimbisa bhiriji, AIT yakasimbisa anchor inobatanidza bhiriji arch uye kongiri base ine kabhoni fiber. ”
Nekubudirira kwechirongwa ichi, Washington State Department of transportation yakagadziridza mazambuko ayo kuti ibvumidze kuvakwa kwemamwe mabhiriji akaumbwa. Sweeney anotarisira zvakare kuti iwe unogona kuwana mabhenefiti akawanda anopihwa neakaumbwa mabhiriji uye kukurudzira kumwe kushandiswa kweanosanganiswa mabhiriji zvimiro kumahombekombe ekumadokero. California ichave inotevera kuwedzera chinangwa cheAIT bhiriji.
