Helm Civil, kambani ine muzinda kuEast Moline, Illinois, yakasaina kondirakiti yakakosha zvikuru neArmy Corps of Engineers muRock Island District yekuputsa 12 30-foot-ndege. Batanidza uye isa 63 drilling shafts.
"Chikamu chataifanira kupukuta chakanga chakareba mamita 360 uye mamita mashanu kumusoro," akadaro Clint Zimmerman, maneja wepurojekiti yepamusoro paHelm Civil. "Zvese izvi zvingangoita 7 kusvika 8 tsoka pasi pemvura, izvo zvinopa dambudziko rakasiyana."
Kuti apedze basa iri, Zimmermann anofanira kuwana michina yakakodzera. Kutanga, anoda chikuya chinogona kushanda pasi pemvura. Chechipiri, anoda tekinoroji inobvumira mushandisi kunyatsochengetedza mutsetse paanenge achikuya pasi pemvura. Akakumbira rubatsiro kune vekugadzira migwagwa nekambani yezvigadzirwa.
Mhedzisiro yacho kushandiswa kweKomatsu Intelligent Machine Control (iMC) PC490LCi-11 yekuchera uye Antraquiq AQ-4XL magiya ane yakasanganiswa GPS tekinoroji. Izvi zvinobvumira Helm Civil kushandisa iyo 3D modhi kudzora kudzika kwayo uye kuchengetedza iko kurongeka kana ichikuya, kunyangwe rwizi rukachinja.
"Derek Welge naBryan Stolee vakanyatsobatanidza izvi, uye Chris Potter akaitawo basa rakakosha," akadaro Zimmerman.
Kubata modhi muruoko, kuisa mucherechedzo zvakachengeteka pachikepe parwizi, Helm Civil yakagadzirira kutanga basa. Kana muchina wacho uchikuya uri pasi pemvura, anoshanda anogona kutarisa sikirini iri mubhokisi remucheri uye kuziva paari uye kuti anofanira kusvika papi.
"Kudzika kwekukuya kunosiyana nehuwandu hwemvura yerwizi," Zimmerman akadaro. “Chakanakira tekinoroji iyi ndechekuti tinokwanisa kugara tichinzwisisa pekukuya zvisineyi kuti mvura yakamira sei. Mushandi nguva dzose ane nzvimbo yekushanda yakarurama. Izvi zvinoshamisa zvikuru.”
"Hatina kumbobvira tashandisa 3D modelling pasi pemvura," Zimmerman akadaro. “Tinoshanda tisingaoni, asi tekinoroji yeMC inotitendera kuti tigare tichiziva patiri chaipo.
Kushandiswa kweCommatsu's smart machine control kwakagonesa Helm Civil kupedzisa purojekiti ingangoita hafu yenguva inotarisirwa.
"Chirongwa chekukuya ndechemavhiki maviri," Zimmerman akayeuka. “Takaunza PC490 nemusi weChina, tichibva taisa grinder neChishanu ndokutora mafoto ekudzora nzvimbo yebasa. Takatanga kugaya neMuvhuro uye takaita 60 tsoka neChipiri chete, zvinofadza kwazvo. Takazopedza Friday iyoyo. Iyi ndiyo nzira chete yekubuda nayo." CEG
