Cov Yeeb Nkab Hlau Uas Muaj Qhov Loj: Nkag Siab Txog Kev Hloov Pauv ntawm Tus Nqi Lag Luam

Cov yeeb nkab hlau du(DI yeeb nkab) yog ib feem tseem ceeb ntawm cov haujlwm tsim kho vaj tse. Cov yeeb nkab dej hlau thiab cov yeeb nkab dej phwj hlau yog qhov tseem ceeb heev rau kev muab dej thiab kev tswj dej khib nyiab. Tab sis tus nqi lag luam ntawm cov yeeb nkab no, zoo li tus nqi ntawm 150 hli yeeb nkab hlau, feem ntau hloov pauv. Muaj ntau yam cuam tshuam ua rau cov nqi hloov pauv no.
Tus nqi ntawm cov khoom siv raw yog qhov tseem ceeb tshaj plaws. Tus nqi ntawm cov hlau ore, cov hlau seem, thiab coke ncaj qha cuam tshuam rau cov nqi tsim khoom. Lawv suav txog ntau dua 38% ntawm cov nqi hloov pauv. Thaum tus nqi ntawm cov ntaub ntawv no nce siab, cov chaw tsim khoom ua rau cov neeg siv khoom them ntau dua. Piv txwv li, qhov kev nce nqi tsis ntev los no ntawmCov kav hlau ductile 150 hliyog vim tus nqi hlau npua nce siab.
Cov lus qhia txog khoom kuj muaj feem cuam tshuam loj heev. Lub cheeb ntawmcov yeeb nkab ductile, qhov tuab ntawm phab ntsa (xws li K9 chav kawm), qhov ntsuas siab, thiab kev kho mob tshwj xeeb xws li cov cement linings rau cov kav dej phwj lossis cov txheej tiv taus xeb ua rau tus nqi siab dua. Tus nqi ntawm 150 hli cov kav hlau ductile tuaj yeem sib txawv li 5% vim yog cov yam ntxwv no. Cov kav dej nrog phab ntsa tuab dua lossis qhov ntsuas siab dua kim dua.

Qhov sib npaug ntawm kev muab khoom thiab kev thov hauv kev ua lag luam cuam tshuam rau tus nqi luv luv. Thaum muaj ntau qhov project hauv paus lossis kev kho dua tshiab hauv nroog, qhov kev thov rau cov kav dej ductile nce siab. Tab sis yog tias muaj teeb meem hauv cov saw hlau xa khoom, xws li cov chaw tsim khoom kaw lossis tsis muaj neeg ua haujlwm, qhov kev muab khoom poob qis. Tsis tas li ntawd, kev sib tw los ntawm cov kav dej PVC lossis HDPE tuaj yeem ua rau tus nqi ntawm cov kav dej hlau ductile qis dua rau cov project uas tus nqi yog qhov txhawj xeeb loj.
Cov nqi thauj khoom kuj tseem ceeb heev. Cov kav dej hlau uas ua los ntawm cov khoom yas hnyav heev, yog li kev xa khoom mus rau lwm lub teb chaws raug nqi ntau heev, tshwj xeeb tshaj yog rau kev xa khoom mus deb lossis xa khoom mus deb. Cov nqi no raug ntxiv rau tus nqi kawg.
Yog tias cov neeg koom tes nkag siab txog cov yam no, lawv tuaj yeem daws qhov teeb meem ntawm kev lag luam yeeb nkab hlau uas hloov pauv tau zoo dua. Cov kev paub no pab lawv txiav txim siab zoo dua thaum yuav lossis muag yeeb nkab hlau uas hloov pauv tau. Lawv tuaj yeem kwv yees qhov kev hloov pauv ntawm tus nqi thiab npaj lawv cov haujlwm lossis kev lag luam raws li. Piv txwv li, yog tias lawv paub tias tus nqi khoom siv raw yuav nce siab, lawv tuaj yeem yuav yeeb nkab ua ntej. Lossis yog tias lawv yog cov chaw tsim khoom, lawv tuaj yeem hloov kho lawv cov khoom tsim tawm raws li qhov xwm txheej ntawm kev thov thiab kev muab khoom ntawm kev ua lag luam. Feem ntau, kev nkag siab txog cov yam no yog qhov tseem ceeb rau kev vam meej hauv kev lag luam yeeb nkab hlau uas hloov pauv tau.
