Cov kav dej sib xyaw ua ke peb-seem yog cov khoom siv feem ntau siv hauv cov chaw pov tseg, kev txhim kho hauv av, qhov av, phab ntsa khaws cia thiab lwm yam haujlwm, uas tuaj yeem daws cov teeb meem ntawm kev ntws dej hauv av thiab kev ruaj khov ntawm av. Yog li, nws puas yuav raug kev poob thaum siv?
1. Kev sib raug zoo ntawm cov khoom siv thiab kev poob
1. Lub vas dej ntws uas muaj peb sab sib xyaw ua ke yog ua los ntawm cov yas peb sab uas sib txuas nrog cov geotextile uas dej nkag tau rau ob sab, yog li nws muaj kev ua haujlwm ntws zoo thiab lub zog tensile. Txawm li cas los xij, txhua yam khoom siv yuav raug cuam tshuam los ntawm ntau yam thaum siv, ua rau poob.
2. Kev laus ntawm cov khoom siv yog ib qho ntawm cov laj thawj tseem ceeb rau kev poob ntawm peb-seem kev sib xyaw ua ke dej ntws. Thaum raug tshav ntuj ntev, ultraviolet hluav taws xob yuav ua rau muaj kev hloov pauv photooxidative ntawm cov polymers molecular siab, ua rau cov khoom siv zog thiab kev ua tau zoo txo qis. Kev hloov pauv kub, bioerosion thiab tshuaj lom neeg erosion, thiab lwm yam.
Tej yam tseem yuav ua rau cov txheej txheem laus ntawm cov ntaub ntawv ua haujlwm sai dua.
2. Cov xwm txheej ntawm daim ntawv thov thiab qib kev poob
1, Cov xwm txheej ntawm daim ntawv thov ntawm peb-seem kev sib xyaw ua ke dej ntws network yog ntau yam, thiab qib ntawm kev poob hauv ntau qhov project kuj txawv. Hauv cov chaw pov tseg, nws qhov kev poob yuav sai heev vim yog kev nkag mus ntev ntawm leachate thiab microbial erosion. Hauv cov projects xws li roadbed thiab tunnel, txawm hais tias
Nws tseem yuav raug cuam tshuam los ntawm cov dej hauv av thiab cov av siab, tab sis qib kev poob qis feem ntau me me.
2. Kev ua haujlwm tsis zoo thaum lub sijhawm tsim kho kuj tseem yuav ua rau poob ntawm cov dej ntws sib xyaw ua ke peb-seem. Piv txwv li, kev ncab ntau dhau, kev quav lossis kev sib ntswg yuav ua rau cov qauv ntawm cov khoom puas tsuaj thiab cuam tshuam rau nws cov dej ntws thiab lub zog tensile.
3. Ua rau muaj kev poob thiab kev tiv thaiv
1, Xaiv cov ntaub ntawv zoo: Xaiv cov dej ntws zoo peb-seem uas muaj kev ua tau zoo tiv thaiv kev laus thiab kev tiv thaiv corrosion muaj zog, uas tuaj yeem ua rau nws lub neej ntev dua.
2, Tsim Nyog Tsim Nyog: Raws li cov kev cai tshwj xeeb thiab cov xwm txheej ib puag ncig, tsim qauv tsim thiab cov qauv ntawm lub kaw lus ntws dej kom txo qhov kev ntxhov siab thiab kev nyuaj siab rau cov ntaub ntawv.
3. Kev tsim kho raws li tus qauv: Thaum lub sijhawm tsim kho, cov txheej txheem ua haujlwm yuav tsum tau ua raws li nruj me ntsis kom tsis txhob muaj kev puas tsuaj rau cov khoom siv. Nws tseem yog qhov tsim nyog los txhawb kev saib xyuas zoo thiab kev lees txais ua haujlwm thaum lub sijhawm tsim kho kom ntseeg tau tias kev tsim kho zoo.
4, Kev txij nkawm tsis tu ncua: Lub network dej ntws sib xyaw ua ke peb-seem uas tau muab tso rau hauv kev siv yuav tsum tau tswj hwm thiab tshuaj xyuas tsis tu ncua kom pom thiab daws cov teeb meem uas yuav tshwm sim hauv lub sijhawm.
Los ntawm saum toj no, peb tuaj yeem pom tias cov kav dej sib xyaw ua ke muaj qee qhov kev poob thaum siv. Los ntawm kev xaiv cov khoom siv zoo, kev tsim qauv tsim nyog, kev tsim kho raws li tus qauv thiab kev saib xyuas tsis tu ncua, kev poob ntawm cov khoom siv tuaj yeem txo qis thiab nws lub neej kev pabcuam tuaj yeem ntev dua.
