Liloko tsa Lagrange le Kaho bocha ea Letamo, Ho Buloa Hape|2020-11-10

Basebetsi ba AECOM Shimmick ba bile le matsatsi a 90 a ho aha bocha Lagrange Locks le kamore ea senotlolo sa letamo. Libekeng tsa ho qetela tsa ho ahuoa bocha ha liloko le letamo la Lagrange, ho ile ha sebelisoa likepe tse peli tsa crane ho tšela konkreite. Ka 1939, Sesole sa US Army Corps of Engineers' Lagrange Locks le Dam se ile sa phethoa Nokeng ea Illinois haufi le Beardsville, Illinois, ka leboea ho moo Illinois e kopanang le Noka ea Mississippi. ya Seretse se Seholo. Kamora lilemo tse 81 tsa ts'ebeletso, ka litokiso tse nyane feela ka 1986 le 1988, ha AECOM Shimmick e qala tsosoloso ea $ 117 milione selemong se fetileng, senotlolo sa maoto a 600 le letamo li ne li felile. "LaGrange Major Rehab / Major Maintenance ke konteraka e kholo ka ho fetisisa ea kaho e le 'ngoe e entsoeng ke Setereke sa Rock Island," ho boletse Col. Steven Sattiger, Mookameli oa Setereke sa USACE Rock Island le Moenjiniere oa Setereke. "Lilemong tse 20 tse fetileng, morero o le mong feela oa Rock Island o fetile. boholo ba morero oa Lagrange, empa morero oo o ile oa aroloa ka likonteraka tse ngata 'me oa nka lilemo tse ka bang 10 ho etsoa, ​​​​e leng ntho e fapaneng le morero oa Lagrange. Ho fapana le morero oa Grange, morero oa Lagrange o phetheloa ka nako e le 'ngoe ea kaho. ” likhohola khafetsa le mocheso o feteletseng le litekanyetso tse phahameng tsa tšebeliso li lebisa ho senyeha ho hoholo ha konkreite e notletsoeng le ho fokotsa ts'ebetso le ts'epahalo ea litsamaiso tsa mochini le tsa motlakase. Liloko li bile tsa mela joang ka konkreite ea khale. AECOM Shimmick e ne e filoe mosebetsi oa ho theola senotlolo, ho tlosa sefahleho sa senotlolo, ho kenya liphanele tse ncha tse entsoeng esale pele le ho aha sefahleho sa senotlolo ka liphanele tsa lihlomo tse kentsoeng bakeng sa nako e telele. "Tsela eo Corps e thehiloeng ka eona, e tla ba mosebetsi o boima haholo," ho boletse mookameli oa morero Bob Wheeler, ea neng a sebetsa le Olmsted Locks le Dam. mesebetsi ea kaho ho potoloha liloko, e ka sitisang sephethephethe sa linōka Ho hlile ho thata ho etsa lintho ka tsela eo. Ts'ebetso ea matsatsi a 90 ea ho notlela le ho ntša metsi e qalile ka Phupu, empa AECOM Shimmick o ne a lokela ho koala likheo tse ngata ho pholletsa le morero oa lilemo tse peli. Moroallo nakong ea selemo le lehlabula la 2019 o ne o bolela hore Wheeler le sehlopha sa hae ba ne ba hloka ho hatella mesebetsi ea mosebetsi hore e be e fokotsehileng. fensetere e koetsoeng ea matsatsi a 90 ho tloha ka Phupu ho isa Mphalane 2020. Ka fensetere e thata joalo, Wheeler o itse oa tseba hore ho tla ba "thata haholo." Sehlopha sa AECOM Shimmick se ne se hloka ho kenya lintlha tse ncha tsa li-anchor tsa menyako le mokhoa o mocha oa ho laola mokhoa oa ho bula le ho koala lemati la lithapo. "Ha li kena ka tlas'a metsi, [li-hydraulic cylinders] li atisa ho lutla, 'me seo e tla ba bothata," Wheeler o itse. "Ke taba ea litšenyehelo le tlhokomelo." Sebakeng sa lisilindara tsa hydraulic, mochini o mocha oa ho phahamisa o sebelisa mochini o potolohang o nang le theknoloji ea spindle, eo pele e neng e sa sebelisoe liloko United States. The Marine Corps e ile ea amohela theknoloji ena bakeng sa linotlolo tsa likepe tse tsamaeang ka tlas'a metsi tse neng li sebelisa li-spindle ho bula le ho koala likheo le likou tsa torpedo. . Moog moetsi oa rotary actuator o fana ka litaelo tse qaqileng tsa ho kenya.Hore actuator e sebetse hantle, ts'ebetsong e hloka ho nepahala. Wheeler o itse: "Li nka sebaka se senyenyane haholo ho feta lisilindara tsa setso." Ha re lekanya shaft le li-spline moo mochini oa rotary o kentsoeng teng, e tlameha ho ba ka har'a lisenthimithara tse sekete - ha e le hantle ke linotlolo le matamo a kang ana. haeba e le ka har'a lisenthimithara tse robeli, u hantle. " Thepa e boima ka har'a sebaka se kopaneng sa senotlolo sa noka le letamo li kenyelletsa krene ea lithane tse 300 ka thoko ho naha, krene ea lithane tse 300 ho ea holimo le krene ea lithane tse 300 ho theosa le noka. ea hlooho e kholo le senotlolo. Krine ea boima ba lithane tse 150 e lutse holim'a seketsoana se ka ntle ho lerako la noka, 'me li-crane tse peli tse boima ba lithane tse 60 li ka har'a ntlo.Ho na le li-crane tse peli tsa lithane tse 130 le krene ea lithane tse 60 leboteng la naha. Li-cranes tsena li sebelisetsoa ho beha mangolo a ketane hammoho le konkreite e ncha bakeng sa mabota a senotlolo, 'me li-crane li behoa ka libakete. Basebetsi ba AECOM Shimmick ba ngotse lihora tse 200,000 ka likhoeli tse tharo le halofo. Ha ba le tlhōrōng, khokahanyo ea thepa e boima le likhokahano li ne li kenyelletsa basebetsi ba 286 ba sebetsang lihora tse tšeletseng tsa lihora tse 10 ka kamoreng ea senotlolo ea maoto a 600 le bophara ba maoto a 110 ka bophara. "Re sebetsa fatše ho tloha mahlakoreng a mabeli a senotlolo," Wheeler o itse. "Mahlakore ka bobeli ka nako e le 'ngoe. Hoa makatsa. Re na le tsamaiso e ntle ea moralo moo re rerang lintho tsena tsohle ka pele. E tšoana le Lean, empa e tsepamisitse maikutlo haholoanyane. e kenyelletsang basebetsi ba masimong le ba mesebetsi ea matsoho le ho fana ka maikutlo letsatsi le letsatsi." Mokonteraka oa ka tlas'a metsi JF Brennan oa La Crosse, Wisconsin o fane ka meralo ea metsing le ba qoelang metsing. ho phunya le ho hlwekisa.Brennan le AECOM Shimmick ba ile ba e tlatsa ka konkreite e le hore e se hlole e sebetsa mme e se ke ya jara boikarabelo ba ho romelwa.Mekgwa ya sejwalejwale ya ho hlwekisa e kentswe tsamaiso e ntjha ya taolo. "U ke ke ua tšela konkreite moo ho nang le foromo joalokaha u ne u tloaetse, ebe u e beha ka har'a mela e meraro ea skrine 'me u qete. E tlameha ho ba e nepahetseng haholo, "Wheeler o itse. Re e khaola, ebe re phunya maoto a ka bang 6 ka liankora, ra kenya sebopeho, ebe re kenya mini shaft ka har'a eona ebe re e kenya ka boutu ho ea ka Sebopeho, ebe re kenya rotary actuator ho eona. - mosebetsi oo u atisang ho o etsa setsing sa motlakase, empa bohareng ba senotlolo ka ntle." Ho sa tsotellehe ho qeta liloko tsohle ka nako ea matsatsi a 90, AECOM Shimmick o ile a qeta morero ona ka nako, 'me Nōka ea Illinois e buletsoe ho tsamaisa likepe ho tloha bohareng ba October. Tse hlano ho tse robeli tsa linotlolo le matamo a haufi le Noka ea Illinois li phethiloe.
