Kev sim txoj kev ntawm hluav taws xob cua sov raj: Pull-out pas nrig tensile xeem, cov ntaub ntawv qhov chaw: Tib neeg lub koom pheej ntawm Tuam Tshoj Machinery kev lag luam Standard JB/T2379-2016 "Hlau Tubular Hluav taws xob cua sov Element"
6.2 Pull-out pas nrig rub test
Cov ntsiab lus raug kho, thiab cov txheej txheem hnyav, suav nrog cov ntawv txuas uas yuav tsum tau dai rau ntawm tus pas nrig tawm, raug tshem tawm vertically mus rau tus pas nrig tawm rau 3 feeb, thiab tom qab ntawd tshuaj xyuas.
Cov kev cai tshuaj xyuas yog raws li nram no:
Cov pas nrig txhuas yuav tsum tuaj yeem tiv taus qhov ntsuas tensile ntev 3min yam tsis muaj kev hloov pauv thiab tawg, thiab qhov ntsuas tensile quab yuam yog 70 feem pua ntawm cov tensile quab yuam ntawm cov pas nrig, tab sis tsis ntau tshaj 1000N.
