Xa iBarbara Walker Crossing yaqalwa okokuqala ngo-2012, umsebenzi wayo ophambili yayikukugcina abakhweli kunye neembaleki kwi-Portland's Wildwood Trail kwingxaki yokuphepha ukugcwala kwi-West Burnside Road.
Yaba bubungqina boyilo lwe-aesthetically consciously consciously, ukudibanisa okuluncedo kunye nobuhle kuluntu oluxabisa (kwaye lufuna) zombini.
Igqitywe ngo-Okthobha ka-2019 kwaye yavulwa kwangaloo nyanga inye, ibhulorho yindlela yokuhamba yabahambi ngeenyawo ubude obuziimitha ezili-180 ecetywe ukuba igobe kwaye iyilelwe ukuba idibane nehlathi elijikelezileyo.
Yenziwe ngaphandle kwendawo yiNkampani yeNsimbi ePhakamileyo yasePortland engasekhoyo, yasikwa yangamacandelo amathathu aphambili, emva koko yathunyelwa ngeelori ukuya kwindawo.
Ukuhlangabezana neemfuno ezibonwayo kunye nezokwakha ezithetha ukusebenzisa imathiriyeli eya kuphumeza zonke iinjongo ezikhethekileyo zeprojekthi, zombini ubugcisa kunye nesakhiwo.Oku kuthetha ukusebenzisa imibhobho - kulo mzekelo 3.5″ kunye 5″.corten (ASTM A847) ityhubhu yentsimbi yesakhiwo eyenzelwe izakhiwo ezifuna i-welded okanye iibholiti zemibhobho enye into edityanisiweyo yepeyinti eveziweyo ihlathi elidityanisiweyo kunye nokudityaniswa kwemibhobho iyavezwa. py.
U-Ed Carpenter, umyili kunye nomzobi okhethekileyo kwiindawo ezinkulu zofakelo lukawonkewonke, wathi wayeneenjongo ezininzi engqondweni xa ekhulelwa ibhulorho.Phakathi kwabo, ibhuloho kufuneka idityaniswe kumxholo wehlathi, nto leyo ukuqhubela phambili kwemvakalelo kunye namava omzila, kwaye kufuneka ibe yinto enqabileyo kwaye ibonakale ngokusemandleni.
“Ngenxa yokuba olona sukelo lwam lubalulekileyo yayikukuyenza ibhulorho ibe-ethe-ethe yaye icace, ndandifuna ezona zinto zisemgangathweni kunye neyona nkqubo ifanelekileyo yolwakhiwo—ngoko, iintsimbi ezintathu eziziintambo,” utsho uCarpenter, okwangumthandi wangaphandle..Isebenza kwisixokelelwano esikhulu sendlela yasePortland iminyaka engaphezu kwama-40.” Usenokuyakha ngezinye izinto, kodwa imibhobho yentsimbi okanye imibhobho lukhetho olusengqiqweni.
Ngokwembono yolwakhiwo olusebenzayo, ukufikelela kuko konke oku akukho lula. UStuart Finney, injineli yesakhiwo kwiofisi yasePortland yefemu yobunjineli ye-KPFF kunye nowayesakuba ngumanejala weprojekthi yebhulorho, uthe ngempumelelo ukuwelda onke amacandelo kwiintlangano zeTYK apho yonke imibhobho exhasayo idibana khona mhlawumbi yayiyeyona nto inzima kakhulu. iqela lokwakha.
UFinney, obeqhelisela lo msebenzi kangangeminyaka engama-20 uthi: “Eyona nto ibalulekileyo ilungu ngalinye lahlukile.” Kwakufuneka badibanise yonke le mibhobho ukuze idityaniswe kwindawo enye, ukuze bakwazi ukufumana izinto zokuwelda ezaneleyo kuyo yonke imibhobho.
Ibhulorho yabahambi ngeenyawo kaBarbara Walker inqumla kwindlela yasePortland enezothutho eziphezulu iBurnside Road. Yaqala ukusebenza ngo-Okthobha wama-2019. UShane Bliss
“IiWelds kufuneka ziguqulwe ngokupheleleyo.I-welding inokuba yenye yezona ndawo zintsonkothileyo kwimveliso. ”
I-Ferry's namesake, uBarbara Walker (1935-2014), ibiyintsika yemizamo yolondolozo yasePortland iminyaka, kwaye unamandla endalo ngokwakhe.Udlale indima ebonakalayo kwiiprojekthi ezininzi zoluntu ePortland, kuquka iMarquam Nature Park, iPioneer Courthouse Square kunye nePowell Butte Nature Park. Umzila kunye neBridge.
Kanye njengoko Walker wanyusa malunga $500,000 ukusuka kuluntu Pioneer Courthouse Square ($ 15 ngelitye lokugalela), nonprofit Portland Parks Foundation wanyusa $2.2 yezigidi ukusuka malunga 900 iminikelo yabucala ukunceda inkxaso-mali bridge.The City of Portland, Portland Parks & Recreation kunye namanye amaqumrhu anikele intsalela malunga $4 million iindleko.
Umchweli uthe ukudibanisa amazwi kunye namazwi amaninzi kwiprojekthi kubonakalise umngeni, kodwa kufanelekile.
"Ndicinga ukuba awona mava abalulekileyo yintsebenziswano enkulu yoluntu, ukuzingca okukhulu, kunye nokuzibandakanya okukhulu - abantu bayayihlawula loo nto," utshilo uCarpenter.Ngumzamo nje omkhulu wendibaniselwano.”
UFinney wongeze ukuba yena neqela lakhe, kunye nabavelisi abanoxanduva lokuzisa uyilo ebomini, kwafuneka boyise imiceli mngeni emininzi kwimodeli ye-3D abayenzayo, ngenxa yabo bonke ubucukubhede bamalungu kunye nokufakwa.
“Sisebenza neenkcukhaca zethu ukuqinisekisa ukuba zonke iimodeli ziyahambelana kuba kwakhona, akukho ndawo yempazamo kuninzi lwala malungu ngenxa yokuntsokotha kwejometri,” utshilo uFinney.” Ngokuqinisekileyo intsonkothe ​​ngakumbi kunoninzi.Iibhulorho ezininzi zithe tye, kwanazo zigobileyo zineegophe, kwaye izixhobo zilula.
“Ngenxa yoko, kukho ukuntsonkotha okuninzi okuvelayo kwiprojekthi.Ngokuqinisekileyo ndingatsho ukuba intsonkothe ​​ngakumbi kunesiqhelo [iprojekthi].Kuthatha umsebenzi omninzi ukuba wonke umntu enze le projekthi iphumelele. ”
Nangona kunjalo, ngokutsho kweMchweli, phakathi kwezinto eziphambili kubunzima bebhulorho, yintoni enika ibhulorho isiphumo sayo sisonke yidekhi egobileyo.Ingaba kuyingxaki ukwenza oku?Kakhulu, ewe.
“Ndicinga ukuba uyilo olulungileyo ludla ngokuqala ngokusebenziseka luze ludlulele kwenye into,” utshilo uMchweli.” Yiloo nto kanye eyenzekayo kule bhulorho.Ndicinga ukuba kum, eyona nto ibalulekileyo yidekhi egobileyo.Kule meko, ngokwenene andiziva kakuhle malunga ne-candy bar kuba yonke indlela i-undulating kwaye iyagoba.Andifuni nje ukwenza ujiko olubukhali ekhohlo ukunqumla ibhulorho emva koko ndijike kabukhali ekhohlo ndiqhubeke.
Ibhulorho yabahambi ngeenyawo kaBarbara Walker yenziwa ngaphandle kwendawo, yahlulahlulwe yangamacandelo amabini aphambili, yaza yathunyelwa ngeelori kwindawo ekuyo ngoku.Portland Parks Foundation
“Uyenza njani idesika egobileyo?Ewe, kuyavela, ewe, i-truss ene-chord ezintathu isebenza kakuhle kwigophe.Ufumana umlinganiselo oncomekayo kakhulu wobunzulu ukuya kwi-span.Ke, unokwenza ntoni nge-truss ene-chord ezintathu ukuyenza ibe ntle kwaye Ubuhle, kwaye ubhekiselele ehlathini ngendlela eyenza kubonakale ngathi ayinakuba kwenye indawo?Qala ngokusebenziseka, emva koko uqhubele phambili - lithini igama?- ukuya kwiphupha.Okanye ukusuka kwizenzo ukuya kwintelekelelo .Abanye abantu banokuyenza ngenye indlela, kodwa yile ndlela kanye ndisebenza ngayo.”
Umchweli ubonga kakhulu iqela labasebenzi be-KPFF ngokumnika inkuthazo ethile awayeyidinga ukuze enze iprojekthi yemibhobho engaphaya kwedekhi, eyanika ibhulorho imvakalelo ephilayo, evela ehlathini.
“Kumnandi ukuba nento onokuyinika esi sixeko kwaye uzingce ngayo, kodwa kumnandi ukujongana nomceli mngeni wobunjineli ococekileyo,” utshilo uFinney.
Ngokutsho kwePortland Parks Foundation, malunga nabahambi ngeenyawo abangama-80,000 baya kusebenzisa ibhulorho yabahambi ngeenyawo nyaka ngamnye, besindisa ingxaki yokuwela icandelo lendlela ebona malunga neenqwelo ezingama-20,000 ngosuku.
Namhlanje, ibhulorho iyaqhubeka nombono kaWalker wokudibanisa abahlali basePortland kunye neendwendwe kubuhle bendalo engqongileyo.
“Kufuneka sinikeze abantu basezidolophini ithuba lokufikelela kwindalo,” uWalker (ocatshulwe liZiko leHlabathi lamaHlathi) wakha wathi.” Imincili ngendalo ivela ngokuba ngaphandle.Ayinakufundwa kwi-abstract.Ngokuzibonela ngokwabo indalo, abantu banomnqweno wokuba ngamagosa omhlaba.”
