Yuav Qhia Li Cas Thiab Tiv Thaiv Kab Ntsig Hauv av Ntuj

3. Saib cov ntsuas hauv av: Qee zaum, cov ntsuas hauv av tuaj yeem pab txheeb xyuas qhov muaj cov kav dej hauv av. Nrhiav cov paib xws li cov ntsuas roj, cov kav dej, lossis cov cim ceeb toom uas qhia txog qhov sib thooj ntawm cov kav dej. Cov ntsuas no tuaj yeem muab cov ntsiab lus tseem ceeb kom tsis txhob khawb.

4. Siv Ground Penetrating Radar (GPR): Rau kev txheeb xyuas qib siab dua, siv cov cuab yeej hauv av nkag mus rau radar. GPR siv hluav taws xob nthwv dej txhawm rau txheeb xyuas cov khoom siv hluav taws xob hauv av, muab cov duab meej ntawm qhov chaw hauv qab no. Txoj kev no muaj txiaj ntsig tshwj xeeb hauv thaj chaw uas daim ntawv qhia kev siv hluav taws xob tuaj yeem dhau los lossis tsis raug.

Tiv thaiv Underground Natural Gas Pipelines

Thaum koj tau txiav txim siab qhov chaw ntawm cov kav dej hauv av, cov kauj ruam tom ntej yog los tiv thaiv lawv. Nov yog qee cov tswv yim zoo:

1. Siv cov ntaub ntawv zoo: Thaum txhim kho lossis kho cov kav xa hluav taws xob, nws yog ib qho tsim nyog yuav tsum siv cov ntaub ntawv zoo uas tuaj yeem tiv taus lub siab thiab cov teeb meem ntawm kev teeb tsa hauv av. Peb lub tuam txhab tau tsim nyob rau hauv 1993 thiab tshwj xeeb hauv kev tsim welded kav siv cov cuab yeej siv siab heev thiab cov ntaub ntawv zoo. Peb muaj peev xwm tsim tau txhua xyoo ntawm 400,000 tons ntawm kauv steel kav, kom ntseeg tau tias peb cov khoom ua tau raws li kev lag luam tus qauv siab tshaj plaws ntawm kev ua haujlwm ntev thiab kev nyab xeeb.

2. Xyaum cov txheej txheem kev teeb tsa kom zoo: Cov txheej txheem kev teeb tsa kom zoo yog qhov tseem ceeb rau kev tiv thaiv hauv avgas kab. Qhov no suav nrog xyuas kom cov raj xa dej tau faus rau ntawm qhov tob kom raug, siv cov ntaub pua tsev tsim nyog, thiab tsis txhob muaj qhov khoov ntse uas tuaj yeem ua rau cov kav dej tsis muaj zog.

3. Kev Tshawb Fawb thiab Kev Kho Kom Zoo: Nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo tshuaj xyuas thiab tswj cov kav dej hauv av kom pom cov teeb meem tshwm sim ua ntej lawv yuav ua teeb meem loj. Qhov no suav nrog kev kuaj xyuas cov dej xau, corrosion, thiab lwm yam cim ntawm kev hnav thiab tsim kua muag. Peb cov kav dej welded yog tsim los tiv thaiv kev nruj ntawm qhov chaw nyob hauv av, txo qhov kev xav tau ntawm kev hloov ntau zaus.

4. Kev cob qhia cov neeg ua haujlwm thiab cov tswv tsev: Kev kawm yog qhov tseem ceeb rau kev tiv thaiv kev sib tsoo ntawm cov roj av hauv av. Cov neeg ua haujlwm koom nrog hauv cov haujlwm excavation yuav tsum raug cob qhia txog qhov tseem ceeb ntawm kev txheeb xyuas thiab tiv thaiv cov roj kab. Cov tswv tsev yuav tsum paub txog cov kev pheej hmoo uas cuam tshuam nrog kev khawb ze ntawm cov kab hluav taws xob thiab qhov tseem ceeb ntawm kev hu xov tooj rau cov kev pabcuam hluav taws xob ua ntej pib ua haujlwm.

nyob rau hauv xaus

Kev txheeb xyuas thiab tiv thaiv cov kav dej hauv av yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab tiv thaiv kev sib tsoo. Los ntawm kev sab laj cov ntawv qhia chaw siv hluav taws xob, hu ua ntej kev khawb, thiab siv cov cuab yeej siv siab heev xws li hauv av nkag mus rau radar, koj tuaj yeem txheeb xyuas cov kav dej kom zoo. Tsis tas li ntawd, siv cov ntaub ntawv zoo, siv cov txheej txheem kev teeb tsa kom raug, thiab kev tshuaj xyuas tsis tu ncua yuav pab tiv thaiv cov txheej txheem tseem ceeb no. Peb lub tuam txhab tau cog lus los muab cov kav dej ruaj khov uas ua tau raws li cov kev xav tau ntawm cov khoom siv hauv av, ua kom muaj kev nyab xeeb thiab txhim khu kev qha roj xa tuaj rau xyoo tom ntej.
