Txoj Kev Loj Hlob nyob rau hauv daim ntawv thov ntawm ntau yam kev soj ntsuam zoo npog ntawm txoj kev hauv nroog

Kev soj ntsuam zoo npog yog ib feem ntawm txoj kev hauv nroog. Hauv cov txheej txheem ntawm kev tsim kho nroog, kev tsim kho txoj kev yog ib qho tseem ceeb rau kev sim nws cov txiaj ntsig. Ob leeg rau cov qhua txawv teb chaws thiab cov neeg nyob hauv zos. "Lub npog manhole uas ploj lawm" yog ib qho duab ntxoov ntxoo, uas yuav tsis tsuas yog ua rau tsis yooj yim rau kev mus ncig, tab sis kuj ua rau muaj kev sib tsoo, uas yuav ua rau muaj kev puas tsuaj loj rau cov khoom ntiag tug thiab cov neeg raug tsim txom. thiab siv manhole npog yuav tsum yog lub ntsiab lus tseem ceeb.

Tuam Tshoj txoj kev tshuaj xyuas ntawm manhole npog tau kwv yees li peb theem, thawj theem ntawm nruab nrab-1990s. Ua ntej qhov no, feem ntau ntawm cov kev soj ntsuam zoo npog yog cov khoom siv ntxiv, nrog ntau qhov sib txawv; Vim hais tias lub hwj chim pipeline tsis faus tob, tsis siv manhole npog. Nyob rau hauv nruab nrab-1990s, ib tug xov tooj ntawm reinforced pob zeb manhole npog tau hloov nrog steel manhole npog. Txawm li cas los xij, cov kab no ntawm cov manhole npog yog yooj yim rau xeb thiab poob tawm hauv qhov chaw ntub dej.

Qhov thib ob theem yog qhov kawg ntawm xyoo 1990, Tuam Tshoj tau pib tsim cov qauv ntawm manhole npog, thiab pib txhawb kev siv cov cam khwb cia hlau manhole npog, thiab cov ncej ntawm kev soj ntsuam zoo tau hloov raws li. Vim qhov zoo corrosion kuj ntawm cam khwb cia hlau cov ntaub ntawv, ib tug unified standard specification tau raug formulated. Yog li ntawd, ib feem tseem ceeb ntawm qhov kev kuaj xyuas qhov zoo npog no tseem siv tau.

Qhov thib peb theem yog tias tom qab xyoo 2008, nrog kev tshwm sim ntawm cov ntaub ntawv tshiab thiab kev siv tshuab tshiab, cov hom tshiab manhole npog feem ntau suav nrog FRP manhole npog, steel fiber ntau manhole npog thiab composite manhole npog, thiab lwm yam. Cov manhole npog tau zoo dua los tiv thaiv corrosion. thiab kev tiv thaiv tub sab nyiag ntau dua li cov khoom siv hlau cam khwb cia, thiab lub suab ntawm tib neeg trampling lossis tsheb dov yog me dua.

Daim ntawv thov sib txawv ntawm cam khwb cia hlau manhole npog

Cam khwb cia hlau soj ntsuam zoo npog muaj qhov zoo ntawm kev tiv thaiv corrosion, thiab ntau lub manhole npog tseem zoo tom qab siv sijhawm ntev. Yog li ntawd, nws yog dav siv. Qee cov tuam txhab lag luam tab tom txiav txim siab ntxiv cov nplhaib roj hmab rau cam khwb cia hlau manhole npog kom txo lawv lub suab nrov. Kuj tseem muaj cov tuam txhab tsim khoom los txhim kho nws cov xauv kom daws tau qhov teeb meem ntawm kev ua haujlwm tsis txaus los tiv thaiv tub sab.

Txawm hais tias kev tshuaj xyuas cov npog qhov dej yuav zoo li tsis tshua muaj txiaj ntsig hauv nroog cov lus qhia thiab kev tswj hwm. Txawm li cas los xij, nws yog ib qho tseem ceeb hauv kev tswj hwm hauv nroog, uas yog qhov tseem ceeb rau kev zoo nkauj ntawm lub nroog, kev nyab xeeb ntawm pej xeem thiab kev tiv thaiv cov kav dej. Rau kev npaj thiab kev tswj xyuas hauv nroog, nws yog ib qho tsim nyog yuav tsum tau siv cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab los soj ntsuam cov npog zoo thiab ntxiv dag zog rau kev tswj hwm. Nyob rau tib lub sijhawm, nws tuaj yeem txhawb kev kho "kev kos duab" ntawm manhole npog, thiaj li ntxiv cov xim ci rau kev nyab xeeb, yooj yim thiab kev zoo nkauj ntawm lub nroog.

Cov ntsiab lus tseem ceeb: kev tsim kho hauv nroog, kev tswj xyuas txoj kev, xyuas kom zoo npog, lub neej hauv nroog
