Cov Kav Hlau Hluav Taws Xob

Cov raj xa dej hluav taws xob (EMT), feem ntau hu ua phab ntsa nyias, yog ib txoj kab hlau uas muaj cov voj voog ncig, uas tsis muaj xov, thiab ntev li 10′. Kuj muaj ntev li 20′. EMT muaj nyob rau hauv qhov loj me ntawm 1/2” txog 4”. Sab nraud yog galvanized rau kev tiv thaiv xeb thiab sab hauv muaj cov txheej txheem organic uas tiv taus xeb. EMT raug teeb tsa los ntawm kev siv cov ntsia hlau teeb lossis cov khoom sib txuas thiab cov khoom sib txuas. Nws raug tso cai kom muaj cov khoom sib txuas ua ke uas muaj cov raj zoo li "belled" nthuav dav ntawm ib kawg nrog cov ntsia hlau teeb. EMT nrog cov khoom sib txuas ua ke muaj nyob rau hauv qhov loj me ntawm 1-1/4 txog 4.
