Azikho iindawo zokusebenza ezimbini ezifanayo, kodwa zihlala zinento enye efanayo: zombini zingaphezulu kwamanzi. Oku kwakungenjalo xa iHelm Civil yakha ngokutsha iisluice kunye namadama oMkhosi weeNjineli zoMkhosi kuMlambo iMississippi eRock Island, eIllinois.
Isitshixo kunye neDama le-15 lakhiwa ngo-1931 ngocingo lwamaplanga kunye nezibonda. Ukutyhubela iminyaka, i-barge traffic eqhubekayo ibangele ukungaphumeleli kwesiseko esidala kudonga olusezantsi olusetyenziswa yi-barge ukungena nokuphuma kwigumbi lokutshixa.
I-Helm Civil, inkampani enekomkhulu e-East Moline, e-Illinois, ityikitye isivumelwano esibaluleke kakhulu kunye ne-Army Corps of Engineers kwiSithili sase-Rock Island ukudiliza i-12 30-foot-aircraft. Dibanisa kwaye ufake iishafti zokomba ezingama-63.
"Inxalenye ekufuneka siyipolishi yayiziimitha ezingama-360 ubude kunye neemitha ezi-5 ukuphakama," utshilo uClint Zimmerman, umphathi omkhulu weprojekthi eHelm Civil. "Yonke le nto imalunga ne-7 ukuya kwi-8 yeenyawo ngaphantsi kwamanzi, nto leyo ibeka umngeni okhethekileyo."
Ukuze ugqibezele lo msebenzi, uZimmermann kufuneka afumane izixhobo ezifanelekileyo. Okokuqala, ufuna isixhobo sokusila esinokusebenza ngaphantsi kwamanzi. Okwesibini, ufuna iteknoloji evumela umqhubi ukuba agcine ngokuchanekileyo i-slope xa esila ngaphantsi kwamanzi. Wacela uncedo koomatshini bendlela kunye nenkampani yokubonelela.
Isiphumo kukusetyenziswa kweKomatsu Intelligent Machine Control (iMC) PC490LCi-11 excavators kunye ne-Antraquiq AQ-4XL yokusila enobuchwepheshe obuhlangeneyo beGPS. Oku kuya kuvumela i-Helm Civil ukuba isebenzise imodeli ye-3D ukulawula ubunzulu bayo kunye nokugcina ukuchaneka xa ukugaya, nokuba umgangatho womlambo uyaguquguquka.
"UDerek Welge noBryan Stolee badibanisa ngokwenene, kwaye uChris Potter naye wadlala indima ebalulekileyo," kusho uZimmerman.
Ukubamba imodeli ngesandla, ukubeka i-excavator ngokukhuselekileyo kwi-barge emlanjeni, i-Helm Civil ilungele ukuqala umsebenzi. Xa umatshini usila ngaphantsi kwamanzi, umsebenzi unokujonga iscreen esikwikhabhathi ye<em>excavator aze azi ngokuthe ngqo apho akhoyo kwanokuba kufuneka aye kude kangakanani na.
"Ubunzulu bokugaya buhluka kunye nenqanaba lamanzi omlambo," kusho uZimmerman. “Inzuzo yobu buchwepheshe kukuba siyakwazi ukusoloko siqonda ukuba sigaya phi nokuba singakanani na inqanaba lamanzi. Umsebenzisi uhlala enendawo yokusebenza echanekileyo. Oku kuchukumisa kakhulu.”
“Asikaze sisebenzise imodeli ye-3D ngaphantsi kwamanzi,” utshilo uZimmerman. “Besingasebenza ngokungaboni, kodwa itekhnoloji ye-iMC isivumela ukuba sihlale sisazi ukuba siphi na.
Ukusetyenziswa koomatshini bokulawula obukrelekrele bakaKomatsu kwenze ukuba iHelm Civil igqibezele iprojekthi phantse kwisiqingatha sexesha elilindelekileyo.
"Isicwangciso sokusila siseeveki ezimbini," ukhumbule uZimmerman. “Sizise iPC490 ngoLwesine, emva koko safaka igrinder ngoLwesihlanu safota iindawo zolawulo ezijikeleze indawo yokusebenza. Siqale ukugaya ngoMvulo kwaye senza iinyawo ezingama-60 ngoLwesibini kuphela, nto leyo enomtsalane kakhulu. Sigqibele ngolwesihlanu. Le kuphela kwendlela yokuphuma.” I-CEG
