Tsis ntev los no, peb covTus neeg siv khoom Costa Rica, Yawg Hussein, tau mus xyuas peb lubHoobkas hlau phajrau kev tshuaj xyuas ntawm qhov chaw thiab kev sib pauv txuj ci. Thaum lub sijhawm mus ntsib, peb pab neeg tau nrogYawg Husseinmus ncig xyuas tag nrho lub hauv paus tsim khoom thiab ua qauv qhia txog tag nrho cov txheej txheem txij li thaum tsim khoom thiab khaws cia mus txog rau kev tshuaj xyuas zoo.
Hauv thaj chaw tsim khoom, peb tau tsom mus rau kev qhia txog cov kab ntau lawm uas ua haujlwm tau zoo uas muaj peev xwm muab khoom tau ruaj khovASTM A709 Qib 50 hlau phajCov kab ntau lawm no kuj tseem tuaj yeem tsim lwm cov phaj hlau Asmeskas uas siv ntau, suav nrogASTM A36thiabA572 Qib 50Tag nrho cov hlau phaj American standard uas tau hais los saum toj no tuaj yeem ua tiav kev muab khoom ruaj khov los ntawm cov kab ntau lawm no.
Tom qab ntawd, peb tau mus rau lub tsev rau khoom ua ke. Nyob ntawd,SGScov neeg soj ntsuam tau ua haujlwm ntawm qhov chaw. Peb tau coj cov qauv raukev kuaj xyuas khawb, kev ntsuam xyuas tensile, thiab lwm yam kev tshuaj xyuas kev tshaj lij, lees paub tias cov ntaub ntawv ua tau raws li qhov xav tauASTM A709cov qauv yuav tsum tau ua.
Mr. Hussein kuj tau tshuaj xyuas peb lub tsev loj loj uas muaj ntau yam hlau phaj Asmeskas xws liA36thiabA572 Qib 50, nrog rau cov khoom muag ntau txaus los txhawb kev xa khoom sai rau cov neeg siv khoom txawv teb chaws.
Peb kuj tau qhia txog cov txheej txheem dov, qhov twg qhov loj ntawm cov txheej txheem tuaj yeem hloov kho los ntawm3000 millimeters to 1500 millimeters, nrog kev hloov kho kom raug rau qhov ntev thiab dav los ntawm ntau qhov kev dov. Tsis tas li ntawd, txhua daim hlau phaj raugKev kuaj ultrasonic 100% (UT)Txawm hais tias cov hlau phaj twb tau raug sim ib zaug los ntawmUTntawm cov kab ntau lawm, ntau tus neeg siv khoom, suav nrog peb cov neeg siv khoom Costa Rican, tseem thov kom muaj qhov thib obKev tshuaj xyuas UT by SGSkom ntseeg tau tias tsis muaj qhov tsis zoo thiab muaj kev ntseeg siab dua ntawm cov khoom.
Qhov kev tshuaj xyuas ntawm qhov chaw no tau ua rau muaj kev ntseeg siab thiab kev nkag siab ntawm ob tog. Lawv tau sib tham tob txog cov lus qhia ntawm cov khoom, kev tswj xyuas zoo, thiab cov xaj tom qab, tsim lub hauv paus ruaj khov rau kev koom tes ntev ntawm peb lub tuam txhab thiab peb cov neeg koom tes Costa Rican.
