Gufunga Lagrange no Kwubaka Urugomero, Gufungura | 2020-11-10

Abakozi ba AECOM Shimmick bari bafite iminsi 90 yo kongera kubaka Lockrange hamwe nicyumba cyo gufunga urugomero. Mu byumweru bya nyuma byo kongera kubaka ingufuri ya Lagrange n’urugomero, hakoreshejwe ingarani ebyiri za kane zikoreshwa mu gusuka beto. Mu 1939, Ingabo z’Amerika z’abashoramari ba Lagrange n’urugomero zuzuye ku ruzi rwa Illinois hafi ya Beardsville, muri Illinois, mu majyaruguru y’aho Illinois ihurira n’umugezi wa Mississippi. y'icyondo kinini. Nyuma yimyaka 81 akora, hamwe no gusana byoroheje gusa mu 1986 na 1988, ubwo AECOM Shimmick yatangiraga gusana miliyoni 117 zamadorali yumwaka ushize, gufunga urugomero rwa metero 600 byari byarangiye. Col. Steven Sattiger, umuyobozi w'akarere ka USACE Rock Island akaba na injeniyeri w'akarere, yagize ati: "LaGrange Major Rehab / Major Maintenance ni amasezerano manini yo kubaka yakozwe n'akarere ka Rock Island." ingano yumushinga wa Lagrange, ariko uwo mushinga wagabanijwemo amasezerano menshi kandi byatwaye hafi imyaka 10 kugirango ukore, bitandukanye numushinga wa Lagrange. Bitandukanye n'umushinga wa Grange, umushinga wa Lagrange urangiye ahanini mu gihembwe kimwe cyo kubaka. ” Umwuzure ukabije nubushyuhe bukabije hamwe nigipimo kinini cyo gukoresha biganisha ku kwangirika gukabije kwa beto ifunze kandi bigabanya imikorere no kwizerwa bya sisitemu ya mashini n’amashanyarazi. Ifunga ryanakuze ibyatsi muri beto ishaje. AECOM Shimmick yahawe inshingano zo kubura umwuma, gukuramo isura yacyo, gushiraho imbaho ​​nshya zabugenewe no kongera kubaka isura yo gufunga hamwe nibikoresho byashyizwemo intwaro kugirango birambe. Umuyobozi w’umushinga, Bob Wheeler, wanakoraga ku Ifunga rya Olmsted n’urugomero, yagize ati: "Uburyo Corps yashyizweho, bizaba ari akazi katoroshye." ibikorwa by'ubwubatsi bikikije ibifunga, bishobora guhungabanya urujya n'uruza rw'inzuzi. Biragoye rwose ko ibintu bikorwa gutya. " Imirimo yo gufunga no kumena iminsi 90 yatangiye muri Nyakanga, ariko AECOM Shimmick yagombaga gukora lockout nyinshi mumushinga wimyaka ibiri.Umwuzure mu mpeshyi nimpeshyi ya 2019 bivuze ko Wheeler nitsinda rye bakeneye guhagarika ibikorwa byakazi kugirango bagabanuke idirishya ryo guhagarika iminsi 90 kuva muri Nyakanga kugeza Ukwakira 2020. Muri idirishya rikomeye, Wheeler yavuze ko yari azi ko "bizagorana bidasanzwe." Itsinda rya AECOM Shimmick ryari rikeneye gushyiraho ingingo nshya ya miter yumuryango hamwe na sisitemu nshya yo kugenzura porogaramu yo gufungura no gufunga umuryango wa miter.Kubera umwuzure aho hantu, Corps yashakaga gusimbuza silindari gakondo ya hydraulic nubuhanga bushya. Wheeler ati: "Iyo bagiye mu mazi, [silinderi ya hydraulic] ikunda kumeneka, kandi ibyo bizaba ikibazo." Ni ikibazo kandi ni ikibazo cyo kubungabunga. " Mu mwanya wa silindari ya hydraulic, uburyo bushya bwo guterura bukoresha icyuma kizunguruka gifite ikoranabuhanga rya spindle, ritari ryarigeze rikoreshwa mu gufunga muri Amerika.Ingabo za Marine Corps zakoresheje ubwo buhanga bwo gufunga ubwato bwo mu mazi bwakoreshaga spindles kugira ngo zifungure kandi zifunge ibyuma bya torpedo. . Uruganda rukora imashini rukora Moog rutanga amabwiriza arambuye yo kwishyiriraho.Ku gikorwa kugirango gikore neza, ishyirwa mubikorwa rigomba kuba ryukuri. Wheeler ati: "Bafata umwanya muto ugereranije na silindari gakondo." Iyo dupimye uruzitiro kandi rugatandukanya aho icyuma kizunguruka gishyirwa, kigomba kuba kiri mu gihumbi cya santimetero - cyane cyane mu gifunga n'ingomero nk'iyi, niba iri muri munani ya santimetero, uri mwiza. "Ibikoresho biremereye mubirenge byoroheje byo gufunga uruzi nurugomero birimo toni 300 kumurima, kran ya toni 300 hejuru no hejuru ya toni 300. ya bulkhead no gufunga. Crane ya toni 150 iherereye kuri barge hanze yurukuta rwinzuzi, na crane ebyiri za toni 60 ziri muri kabine.Hari tran ebyiri ebyiri za toni 130 na toni 60 kurukuta rwubutaka. Iyi crane ikoreshwa mugushira amabaruwa yumunyururu kimwe na beto nshya kurukuta, kandi crane igashyirwa hakoreshejwe indobo. Abakozi ba AECOM Shimmick banditse amasaha 200.000 mumezi atatu nigice. Mugihe cyo hejuru, guhuza ibikoresho biremereye hamwe n’itumanaho harimo abakozi 286 bakora amasaha atandatu y’amasaha 10 mu masaha 10 mu cyumba cya feri gifite uburebure bwa metero 600 na 110. Wheeler ati: "Dukora hasi ku mpande zombi zifunze." Impande zombi icyarimwe. Biratangaje. Dufite gahunda nziza yo gutegura aho duteganya ibyo bintu byose imbere. Birasa na Lean, ariko byibanda cyane. birimo abakozi bo mu murima n'ubukorikori no gutanga ibitekerezo buri munsi. " Umushinga wo kubaka amazi yo mu mazi JF Brennan ukomoka muri La Crosse, Wisconsin yatanze gahunda z’inyanja n’abashitsi.Wheeler yavuze ko bagomba kwibira ahantu hahanamye, hagomba gusukurwa no kuvanwaho. Imiyoboro yose yanduye nayo igomba gusanwa. Urugomero rwo mu 1939 rwari rufite umurage uteganijwe kuri gucukura no gusiba.Brennan na AECOM Shimmick yujuje beto kugirango itagikora kandi ntizabazwa kohereza. Sisitemu yo gukora isuku ya kijyambere yashyizwemo na sisitemu nshya yo kugenzura. Wheeler ati: "Ntushobora gusuka beto ahari urupapuro rwabugenewe nkuko bisanzwe, hanyuma ubishyire mumirongo itatu ya ecran hanyuma urangize. Bigomba kuba bisobanutse neza." beto. Twarayikatiye, hanyuma ducukumbura metero zigera kuri 6 hamwe na ankeri, dushyiramo imiterere, hanyuma dushyiramo iyi shitingi ya mini hanyuma tuyihindura kuri Structurally, hanyuma dushyiramo rotateur ya rotu. - akazi usanzwe ukora mu ruganda rw'amashanyarazi, ariko hagati yo gufunga hanze. " Nubwo yarangije gufunga byose mugihe cyiminsi 90, AECOM Shimmick yarangije umushinga mugihe, kandi umugezi wa Illinois wafunguye ubwikorezi bwo gutwara ibicuruzwa kuva hagati mu Kwakira.Batanu muri funga umunani ningomero zomugezi wa Illinois zararangiye.
