Lagrange Locks uye Dhamu Kuvakazve, Kuvhurazve | 2020-11-10

Vashandi veAECOM Shimmick vaive nemazuva makumi mapfumbamwe ekuvakazve Lagrange Locks uye imba yekuvharisa yedhamu yekuvhara mvura. Mumavhiki ekupedzisira ekuvakwa patsva kwekiyi yeLagrange nedhamu, mabhaji maviri ecrane akashandiswa kudira kongiri. Muna 1939, mauto eUS Army Corps eEngineers 'Lagrange Locks uye Damu akapedzwa paRwizi rweIllinois pedyo neBeardsville, Illinois, kuchamhembe uko Illinois inosangana neMississippi River. yeMadhaka Makuru. Mushure memakore makumi masere nerimwe ebasa, nekungogadziridzwa kudiki muna 1986 na1988, AECOM Shimmick payakatanga kudzoreredza mamirioni zana negumi nenomwe gore rapfuura, kukiyiwa kwemakumbo mazana matanhatu nedhamu zvakapera. "LaGrange Major Rehab / Major Maintenance ndiyo chibvumirano chikuru chekuvaka chimwe chete chakaitwa neRock Island District," akadaro Col. Steven Sattiger, USACE Rock Island District Mukuru uye District Engineer. "Mumakore makumi maviri apfuura, chirongwa chimwe chete cheRock Island chakapfuura. ukuru hwepurojekiti yeLagrange, asi chirongwa ichi chakakamurwa kuita zvibvumirano zvakawanda uye zvakatora makore anoda kusvika gumi kuita, izvo zvakasiyana neprojekti yeLagrange. Kusiyana nepurojekiti yeGrange, chirongwa cheLagrange chinopedzwa mumwaka mumwe chete wekuvaka. " Mafashamo emvura zhinji uye tembiricha yakanyanyisa uye mwero wekushandisa wakakwira zvinokonzeresa kuderera kukuru kwekongiri yakakiyiwa uye kuderedzwa kwekuita uye kuvimbika kwemakanika uye magetsi masisitimu. Makiyi akatomera uswa mukongiri yekare. Iyo AECOM Shimmick yakapihwa basa rekubvisa mvura kukiyi, kubvisa chiso chayo chekiyi, kuisa mapaneru matsva akagadzirwa uye kuvakazve kumeso kwekiyi nemapaneru ezvombo akaiswa kuti agare. "Magadzirirwo akaitwa Corps, richave basa rakaoma," akadaro director wepurojekiti, Bob Wheeler, akashandawo paOlmsted Locks neDam. mabasa ekuvaka akatenderedza makiyi, izvo zvinogona kukanganisa kufamba kwenzizi Zvakaoma chaizvo kuti zvinhu zviitwe nenzira iyoyo. Basa remazuva makumi mapfumbamwe rekuvharira uye rekudhiraivha rakatanga muna Chikunguru, asi AECOM Shimmick aifanirwa kuvharira kunze kwakawanda mukati mechirongwa chemakore maviri. Mafashamo muchirimo nechirimo cha2019 zvaireva kuti Wheeler nechikwata chake vaifanira kumanikidza mabasa ebasa kuita rimwe rakaderedzwa. Kuvhara hwindo remazuva makumi mapfumbamwe kubva munaChikunguru kusvika Gumiguru 2020. Muhwindo rakaoma kudaro, Wheeler akati aiziva kuti "zvichave zvakaoma." Chikwata cheAECOM Shimmick chaifanira kuisa miter door anchor point uye itsva programmable control system yekuvhura nekuvhara gonhi remasasi.Nekuda kwemafashama panzvimbo iyi, Corps yaida kutsiva masilinda echinyakare ehydraulic nehunyanzvi hutsva. "Pavanoenda pasi pemvura, [hydraulic cylinders] inowanzodonha, uye ichava dambudziko," akadaro Wheeler. Panzvimbo pema hydraulic cylinders, iyo nyowani yekusimudza meshini inoshandisa rotary actuator ine spindle tekinoroji, iyo yakanga isati yamboshandiswa mumakiyi muUnited States. Marine Corps yakatora tekinoroji iyi yekukiyira pazvikepe zvepasi pemvura izvo zvaishandisa spindles kuvhura uye kuvhara mabheji uye torpedo bays. . Rotary actuator inogadzira Moog inopa yakadzama yekuisa mirairo.Kuti iyo actuator ishande nemazvo, kuita kunofanirwa kuve kwakarurama. "Vanotora nzvimbo shoma pane masilinda echinyakare," Wheeler akadaro." Kana tikayera shaft uye splines panokwidzwa rotary actuator, inofanirwa kunge iri mukati mechuru chemainji - kunyanya mumakiyi nemadhamu seizvi, kana iri mukati mechikamu chesere chemainji, makanaka. " Midziyo inorema mukati memutsindo wekiyi yerwizi uye dhamu inosanganisira 300-ton crane padivi penyika, 300-ton crane kumusoro kwerwizi uye 300-ton crane zasi kwerwizi. of the bulkhead and lock.A 150-ton crane iri pabarge kunze kwemadziro erwizi, uye maviri matani 60-ton ari mukamba.Kune maviri 130-ton crane uye 60-ton tani pamadziro enyika. Makoni aya anoshandiswa kuisa tsamba dzecheni pamwe nekongiri nyowani kumadziro ekiyi, uye makoni anoiswa uchishandisa mabhaketi. Vashandi veAECOM Shimmick vakanyora maawa 200,000 mumwedzi mitatu nehafu.Pamusoro pepamusoro, kurongeka kwemidziyo inorema uye kutaurirana kwaisanganisira vashandi ve286 vanoshanda maawa matanhatu e10-awa maviri ekuchinja muimba yekuvhara 600-kureba uye 110-foot-wide lock room. "Tinoshanda pasi kubva kumativi maviri echikiko," Wheeler akadaro. "Mativi maviri panguva imwe chete. Zvinoshamisa. Tine chirongwa chikuru chekuronga apo tinoronga zvinhu zvose izvi mberi. Zvakafanana neLean, asi zvakanyanya kutarira kusanganisira vashandi vemumunda nevemhizha uye kupa mhinduro zuva nezuva. " Mukontrakta wepasi pemvura JF Brennan anobva kuLa Crosse, Wisconsin akapa zvirongwa zvemugungwa nevasiya-siyana. Wheeler akati vaifanira kunyura pane nzvimbo dzinonzi bulkhead slots, dzaifanira kucheneswa nekubviswa. dredging and clearing.Brennan uye AECOM Shimmick akaizadza nekongiri kuitira kuti isazoshanda uye irege kuva nemhosva yekutumira.Masisitimu ekuchenesa kwemazuva ano akaiswa nehurongwa hutsva hwekutonga. "Iwe haugone kudurura kongiri uko kune formwork sezvaunowanzoita, wozoiisa mukati memitsara mitatu yechidzitiro uye upedze. Inofanira kunge yakanyatsojeka," Wheeler akadaro. kongiri takaicheka kunze, tobva tadonhedza pasi anenge 6 tsoka nezvibatiso, toisa chimiro mukati, toisa iyi mini shaft mukati ndokuisungirira kuStructurally, tozoisa rotary actuator pairi. - basa raunowanzo kuita musimba remagetsi, asi pakati pekuvhara kunze." Pasinei nekupedza zvivharo zvose munguva ye90-day, AECOM Shimmick akapedza basa racho nenguva, uye Illinois River yakazaruka kutakura ngarava kubva pakati paOctober. Zvishanu zvezvivharo sere nemadhamu ari pedyo neI Illinois River zvakapedzwa.
