Khoom lag luam yog cov khoom tseem ceeb uas cuam tshuam txog kev tsim cov pob zeb thiab cov nqi ntau hauv cov nqi, uas yog tau muab faib ua peb qho, xws li cov khoom hnyav, cov hmoov weighing thiab ua kua.
Feem ntau, cov khoom noj qis dua 20 cubic meters ib xuab moos siv ntau tshaj qhov kev siv, uas yog, pob zeb (pob zeb, pob zeb) nrog lub nplai, xis mas thiab cov ntoo tshauv yog sib nyhav nrog nplai, dej thiab kua pleev, thiab tom qab ntawd cov kua muab tso rau hauv dej thoob rau kev tov ua ntej. Hauv qhov chaw nres tsheb sib xyaw ntawm ntau tshaj 50 cubic meters ib xuab moos, qhov kev ywj pheej weighing ntawm txhua cov khoom siv uas siv yog siv, thiab txhua yam kev ntsuas yog tswj los ntawm cov hluav taws xob nplai thiab microcomputer. Aggregate weighing raug ± 2%, MAAs, hmoov, dej thiab admixture weighing raug hu ± 1%.
