Tsis muaj ob qhov chaw ua haujlwm zoo ib yam, tab sis lawv feem ntau muaj ib qho zoo sib xws: lawv ob qho tib si saum dej. Qhov no tsis yog qhov xwm txheej thaum Helm Civil rebuilt sluices thiab dams rau Army Corps of Engineers ntawm tus dej Mississippi ntawm Rock Island, Illinois.
Xauv thiab Dam 15 tau tsim nyob rau hauv 1931 nrog ntoo laj kab thiab ceg txheem ntseeg. Tau ntau xyoo, kev tsheb thauj mus los tsis tu ncua tau ua rau tsis ua haujlwm ntawm lub hauv paus qub ntawm cov ntawv qhia qis uas siv los ntawm lub nkoj nkag mus rau hauv thiab tawm ntawm lub xauv chamber.
Helm Civil, ib lub tuam txhab hauv paus hauv East Moline, Illinois, tau kos npe rau daim ntawv cog lus tseem ceeb tshaj plaws nrog Army Corps of Engineers hauv Rock Island District kom rhuav tshem 12 30-ko taw dav hlau. Kev sib xyaw ua ke thiab nruab 63 qhov drilling shafts.
Clint Zimmerman, tus thawj coj loj ntawm Helm Civil hais tias "Qhov peb yuav tsum tau polished yog 360 ko taw ntev thiab 5 ko taw siab," said Clint Zimmerman. "Txhua yam no yog hais txog 7 mus rau 8 ko taw hauv qab dej, uas ua rau muaj kev sib tw tshwj xeeb."
Yuav kom ua tiav txoj haujlwm no, Zimmermann yuav tsum tau txais cov cuab yeej tsim nyog. Ua ntej, nws xav tau ib lub grinder uas tuaj yeem ua haujlwm hauv qab dej. Qhov thib ob, nws xav tau thev naus laus zis uas tso cai rau tus neeg teb xov tooj kom tswj tau qhov kev nqes hav thaum sib tsoo hauv qab dej. Nws thov kom lub tuam txhab kev siv tshuab thiab muab kev pab.
Qhov tshwm sim yog siv Komatsu Intelligent Machine Control (iMC) PC490LCi-11 excavators thiab Antraquiq AQ-4XL grinders nrog kev sib xyaw GPS thev naus laus zis. Qhov no yuav tso cai rau Helm Civil siv tus qauv 3D los tswj nws qhov tob thiab tswj qhov tseeb thaum sib tsoo, txawm tias tus dej ntws hloov pauv.
Zimmerman tau hais tias "Derek Welge thiab Bryan Stolee yeej muab cov no ua ke, thiab Chris Potter kuj tau ua lub luag haujlwm tseem ceeb," Zimmerman tau hais.
Tuav tus qauv hauv tes, tso lub excavator kom ruaj ntseg ntawm lub nkoj ntawm tus dej, Helm Civil yog npaj los pib ua haujlwm. Thaum lub tshuab sib tsoo hauv qab dej, tus neeg teb xov tooj tuaj yeem saib lub vijtsam hauv lub tsheb thauj khoom thiab paub meej tias nws nyob qhov twg thiab nws yuav tsum mus deb npaum li cas.
Zimmerman tau hais tias "Qhov tob ntawm kev sib tsoo sib txawv nrog cov dej theem ntawm tus dej," Zimmerman tau hais. "Qhov zoo ntawm cov thev naus laus zis no yog qhov peb tuaj yeem nkag siab tsis tu ncua qhov twg yuav zom tsis hais txog qib dej. Tus neeg teb xov tooj ib txwm muaj txoj haujlwm raug. Qhov no yog qhov ua tau zoo heev. "
"Peb tsis tau siv 3D qauv hauv qab dej," Zimmerman tau hais. "Peb yuav ua haujlwm dig muag, tab sis iMC thev naus laus zis tso cai rau peb ib txwm paub tseeb tias peb nyob qhov twg.
Kev siv Komatsu lub tshuab ntse tswj tau ua rau Helm Civil kom ua tiav qhov project hauv ze li ib nrab ntawm lub sijhawm xav tau.
"Lub phiaj xwm sib tsoo yog ob lub lis piam," Zimmerman nco qab. "Peb tau coj PC490 rau hnub Thursday, thiab tom qab ntawd peb tau teeb tsa lub tshuab sib tsoo rau hnub Friday thiab thaij duab cov ntsiab lus tswj nyob ib puag ncig qhov chaw ua haujlwm. Peb pib sib tsoo rau hnub Monday thiab peb ua 60 ko taw rau hnub Tuesday ib leeg, uas yog qhov zoo heev. Peb pib ua tiav hnub Friday. Nov yog tib txoj kev tawm. " CEG
