Izikhiye ze-Lagrange kanye Nokwakhiwa Kabusha Kwedamu, Ukuvulwa Kabusha|2020-11-10

Izisebenzi ze-AECOM Shimmick zinezinsuku ezingu-90 zokwakha kabusha izingidi zeLagrange kanye negumbi lokukhiya ledamu. Emavikini okugcina okwakhiwa kabusha kwezingidi kanye nedamu laseLagrange, kwasetshenziswa izikebhe ezimbili zama-crane ukuze kuthelwe ukhonkolo. Ngo-1939, i-US Army Corps of Engineers' Lagrange Locks and Dam yaqedwa eMfuleni i-Illinois eduze kwaseBeardsville, e-Illinois, enyakatho nje lapho i-Illinois ihlangana khona noMfula i-Mississippi. yoMdaka Omkhulu. Ngemva kweminyaka engu-81 yenkonzo, nokulungiswa okuncane kuphela ngo-1986 no-1988, lapho i-AECOM Shimmick iqala ukubuyisela u-$117 million ngonyaka odlule, isikhiya esingamamitha angu-600 kanye nedamu kwase kuphelelwe yisikhathi. "I-LaGrange Major Rehab/Major Maintenance iyinkontileka yokwakha eyodwa enkulu kunazo zonke eyenziwe yiSifunda sase-Rock Island," kusho uCol. Steven Sattiger, Umphathi Wesifunda sase-USACE Rock Island kanye Nonjiniyela Wesifunda. "Eminyakeni engu-20 edlule, iphrojekthi eyodwa kuphela ye-Rock Island eyeqile. ubukhulu bephrojekthi yeLagrange, kodwa leyo phrojekthi yahlukaniswa yaba izinkontileka eziningi futhi yathatha iminyaka ecishe ibe ngu-10 ukwenziwa, okuphambene nephrojekthi yeLagrange. Ngokungafani nephrojekthi yaseGrange, iphrojekthi yeLagrange iqedwa ngesizini eyodwa yokwakha. Izikhukhula ezivamile namazinga okushisa aphezulu kanye namazinga aphezulu okusetshenziswa kuholela ekulimaleni okukhulu kukakhonkolo okhiyiwe kanye nokuncipha kokusebenza nokuthembeka kwemishini nezinhlelo zikagesi. Izingidi zikhule ngisho notshani kukhonkolo endala. I-AECOM Shimmick yayinikezwe umsebenzi wokukhipha amanzi emanzini okhiye, isuse ubuso bayo bokukhiya, ifake amaphaneli amasha enziwe ngaphambili futhi yakhe kabusha ubuso bokukhiya ngamaphaneli ezikhali ashunyekiwe ukuze aqine. "Indlela i-Corps emiswe ngayo, kuzoba umsebenzi onzima kakhulu," kusho umqondisi wohlelo u-Bob Wheeler, naye owasebenza e-Olmsted Locks and Dam." Ngaphambi kokuvalwa kwehlobo, sasivule izingidi futhi sisenza nje. imisebenzi yokwakha ezungeze izingidi, okungase kuphazamise ukuhamba kwezimoto emfuleni Kunzima ngempela ukwenza izinto ngaleyo ndlela. Umsebenzi wezinsuku ezingu-90 wokuvala nokukhipha amanzi waqala ngoJulayi, kodwa i-AECOM Shimmick bekufanele ivale kaningi phakathi nephrojekthi yeminyaka emibili. Iwindi lokuvala lezinsuku ezingama-90 kusukela ngoJulayi kuya ku-Okthoba 2020. Efasiteleni eliqine kangaka, uWheeler uthe uyazi ukuthi kuzoba "nzima kakhulu." Ithimba le-AECOM Shimmick lalidinga ukufaka amaphuzu amasha okusetshenzwa kwe-miter door kanye nesistimu entsha yokulawula ehlelekayo ukuze uvule futhi uvale umnyango we-miter.Ngenxa yezikhukhula kusayithi, i-Corps yayifuna ukufaka ubuchwepheshe obusha esikhundleni samasilinda avamile we-hydraulic. "Uma zingena ngaphansi kwamanzi, [amasilinda amanzi] avame ukuvuza, futhi lokho kuzoba yinkinga," kusho u-Wheeler." Esikhundleni samasilinda amanzi, umshini omusha wokuphakamisa usebenzisa i-rotary actuator enobuchwepheshe bokuphotha, obungakaze busetshenziswe okhiye e-United States.I-Marine Corps yamukela lobu buchwepheshe bokukhiya imikhumbi-ngwenya eyayisebenzisa ama-spindles ukuvula nokuvala ama-hatches namatheku e-torpedo. . Umkhiqizi we-Actuator ye-Rotary i-Moog inikeza imiyalelo yokufaka enemininingwane.Ukuze i-actuator isebenze kahle, ukufakwa kufanele kunembile. "Zithatha indawo encane kakhulu kunamasilinda endabuko," kusho u-Wheeler."Lapho sikala i-shaft kanye ne-splines lapho kufakwe khona i-rotary actuator, kufanele ibe phakathi kwenkulungwane yamayintshi - ngokuyisisekelo ezingidini nasemadamini afana nalokhu, uma ingaphakathi kwe-intshi eyisishiyagalombili, ulungile. " Imishini enzima phakathi nendawo yokukhiya umfula kanye nedamu ihlanganisa i-crane engamathani angu-300 endaweni ezungezile, i-crane engamathani angu-300 phezulu nomfula ongamathani angu-300 ezansi nomfula. of the bulkhead and lock.I-crane engamathani angu-150 itholakala phezu kwezikejana ezingaphandle kodonga lomfula, futhi okhreni ababili abangamathani angama-60 basendlini.Kunama-crane amabili angamathani angu-130 kanye nokhreni wamathani angama-60 odongeni lomhlaba. Lawa ma-cranes asetshenziselwa ukubeka i-chain mail kanye nokhonkolo omusha wezindonga zokukhiya, futhi ama-cranes abekwe kusetshenziswa amabhakede. Izisebenzi ze-AECOM Shimmick zirekhode amahora angu-200,000 ezinyangeni ezintathu nesigamu. Esiqongweni, ukuxhunyaniswa kwemishini esindayo kanye nokuxhumana kwakuhlanganisa nabasebenzi abangu-286 abasebenza amashifu ayisithupha amahora angu-10 ekamelweni lokukhiya elingamafidi angu-600 ubude no-110 ububanzi. "Sisebenza phansi kusuka ezinhlangothini zombili zokukhiya," kusho u-Wheeler."Zombili izinhlangothi ngesikhathi esisodwa. Kuyamangalisa. Sinohlelo oluhle lokuhlela lapho sihlela zonke lezi zinto ngaphambili. Kufana ne-Lean, kodwa okugxile kakhulu okubandakanya abasebenzi basensimini kanye nezandla kanye nokunikeza impendulo nsuku zonke." Usonkontileka omncane wokwakha ngaphansi kwamanzi u-JF Brennan wase-La Crosse, e-Wisconsin uhlinzeke ngamapulani asolwandle nabatshuzi. U-Wheeler uthe kwakudingeka batshuze ezindaweni ezincanyana, okwakudingeka zihlanzwe futhi zisuswe. Wonke ama-valve okungcola kufanele alungiswe. ukudonsa nokususa.UBrennan kanye no-AECOM Shimmick bawugcwalise ngokhonkolo ukuze ungasasebenzi futhi ngeke ube nesibopho sokuthunyelwa ngemikhumbi.Izinhlelo zokuhlanza zesimanje zifakelwe uhlelo olusha lokulawula. "Awukwazi ukuthela ukhonkolo lapho kukhona i-formwork njengoba ubungenza ngokujwayelekile, bese uyibeka phakathi kwemigqa emithathu yesikrini bese uqeda. Kufanele inembe kakhulu," kusho u-Wheeler." Khona-ke, uhlelo lwesakhiwo olusuka ku-anchorage luku ukhonkolo Siwunqamule, sabe sesibhoboza phansi cishe ngamamitha ayi-6 ngamahange, safaka isakhiwo, safaka le mini shaft futhi siyibhawudi ku-Structurally, bese sibeka i-rotary actuator kuso. - umsebenzi ovame ukuwenza embonini yamandla, kodwa phakathi nendawo yokukhiya ngaphandle." Naphezu kokuqeda zonke izingidi esikhathini esiyizinsuku ezingu-90, i-AECOM Shimmick yawuqeda umsebenzi ngesikhathi, futhi uMfula i-Illinois uvulelwe ukuthuthwa ngezikebhe kusukela maphakathi no-Okthoba.Ezinhlanu kweziyisishiyagalombili kwezingidi namadamu eduze koMfula i-Illinois seziqediwe.
