Tsis ntev los no, ib pab neeg ntawm cov neeg siv khoom Brazilian tau mus xyuas peb lub Hoobkas koom tes rau kev tshuaj xyuas ntawm qhov chaw, tsom mus rau kev sib tham tob txogCov khoom siv galvanized corrugated culvertthiab cov txheej txheem tiv thaiv xeb. Peb cov neeg ua haujlwm tau nrog cov neeg siv khoom thoob plaws lawv txoj kev ncig xyuas chaw ua haujlwm thiab thaj chaw nthuav qhia, lub chaw ua haujlwm tsim khoom txheem, thiab lub chaw ua haujlwm pleev xim tshwj xeeb. Los ntawm kev soj ntsuam ntawm qhov chaw, kev rhuav tshem cov txheej txheem, thiab kev sib tham nug thiab teb ntsej muag, cov neeg siv khoom tau txais kev nkag siab dav dav txog peb cov qauv tsim khoom thiab cov txheej txheem tswj xyuas zoo.
Cov neeg siv khoom tau mus tob rau hauv cov chaw tsim khoom tseem ceeb kom pom tag nrho cov txheej txheem tsim khoom ntawm cov kav dej galvanized corrugated culvert ncaj qha.Txij li thaum xaiv cov ntawv hlau galvanized thiab kev tsim khoom kom raug mus txog rau qhov kev xaiv cov khoom kawg, peb cov neeg ua haujlwm tau muab cov lus piav qhia ntawm qhov chaw ntawm cov txiaj ntsig tiv taus xeb ntawm cov khoom siv galvanized., nrog rau qhov ruaj khov ntawm cov qauv thiab lub zog compressive ntawm cov khoom tiav lawm, qhia tag nrho cov khoom zoo tshaj plaws rau ntau yam haujlwm tsim kho vaj tse xws li txoj kev loj, qhov av, thiab kev txuag dej.
Lub hom phiaj tseem ceeb ntawm kev mus ntsib no yog cov txheej txheem tiv thaiv xeb hauv lub khw pleev xim, uas tau hais txog lub tuam txhab lub peev xwm kev txawj ntse thiab kev tswj hwm zoo hauvcorrugated yeeb nkabkev tsim khoom. Txij no mus, peb lub tuam txhab yuav txuas ntxiv nthuav dav mus rau hauv kev lag luam txawv teb chaws los ntawm kev muab cov khoom lag luam zoo, hloov pauv tau yooj yim thiab cov kev pabcuam tshaj lij.
