Khoom Description
Lub pas dej da dej geomembranes tau siv dav hauv Kenya rau ntau yam kev tswj dej, suav nrog kev tsim kho thiab tu cov pas dej, pas dej, thiab cov dams.
Hauv Kenya, lub pas dej da dej geomembranes feem ntau yog siv los daws cov teeb meem dej tsis txaus, khaws cov dej nag rau kev ua liaj ua teb, thiab tiv thaiv cov dej hauv av. Lawv ua lub luag haujlwm tseem ceeb hauv kev txuag dej thiab kev tswj hwm, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam arid thiab ib nrab arid uas muaj kev txwv dej.
Cov hom geomembranes feem ntau siv los ua cov pas dej da dej hauv Kenya muaj xws li high-density polyethylene (HDPE) thiab linear low-density polyethylene (LLDPE) geomembranes. Cov ntaub ntawv no raug xaiv rau lawv cov kav ntev, yooj yim, thiab tiv thaiv ultraviolet (UV) hluav taws xob, punctures, thiab tshuaj degradation.
Installation Notes
Thaum txhim kho lub pas dej ua ke geomembrane hauv Kenya, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov kev coj ua hauv engineering thiab cov lus qhia kom ntseeg tau tias cov dej ntim tau ruaj khov thiab kav ntev. Cov txheej txheem kev teeb tsa feem ntau suav nrog kev npaj cov subgrade, tshem cov khoom ntse, thiab compacting av ua ntej nteg cov geomembrane. Cov seams thiab cov pob qij txha tau ua tib zoo welded los yog kub-txheej txheem los tsim ib tug nruam thaiv, thiab tiv thaiv txheej xws li geotextiles yuav siv tau los txhim kho lub liner txoj kev ua tau zoo thiab ntev.
Nws raug nquahu kom sab laj nrog cov kws tshaj lij hauv zos, engineers, lossis cov tuam txhab tshwj xeeb uas muaj kev paub txog hauv kev tsim cov pas dej da dej kom ua raws li cov kev cai hauv zos thiab kom tau txais cov khoom siv geomembrane uas tsim nyog tshaj plaws rau cov phiaj xwm tshwj xeeb. Tsis tas li ntawd, kev tshuaj xyuas kom zoo, kev saib xyuas, thiab kev saib xyuas ntawm lub pas dej ua ke nyob rau lub sijhawm yog qhov tseem ceeb los txheeb xyuas cov teeb meem uas muaj peev xwm thiab ua kom nws cov txiaj ntsig zoo hauv kev ntim dej.
Raws li kev siv thev naus laus zis thiab cov txheej txheem txuas ntxiv mus, nws yog qhov tseem ceeb uas yuav tsum tau hloov kho tshiab ntawm cov kev coj ua tshiab thiab kev tsim kho tshiab hauv cov kav dej liner geomembranes kom ua kom cov dej ntim tau zoo tshaj plaws thiab txo qhov cuam tshuam ib puag ncig. 
Cov kev coj ua tshiab thiab kev tsim kho tshiab hauv Dam Liner Geomembranes
Advanced Geomembrane Materials: Cov neeg tsim khoom tseem niaj hnub tsim cov ntaub ntawv geomembrane tshiab nrog cov khoom zoo dua qub los txhim kho lawv cov kev ua tau zoo. Cov ntaub ntawv no yuav muaj zog, yoog raws, thiab tshuaj tiv thaiv, uas tso cai rau kev ua haujlwm ntev ntev thiab kev ua haujlwm zoo hauv ntau yam ib puag ncig. Composite Geomembranes: Composite geomembranes muab cov ntaub ntawv sib txawv los coj kom zoo dua ntawm lawv tus kheej lub zog. Piv txwv li, ib qho kev sib xyaw liner tuaj yeem suav nrog txheej geomembrane ua ke nrog cov txheej geotextile ntxiv rau kev tiv thaiv kev sib tsoo lossis cov av nplaum geosynthetic (GCL) rau kev txhim kho hydraulic. Geomembrane Leak Detection Systems: Cov txheej txheem xau siab tshaj plaws tau muab tso rau hauv kev teeb tsa lub pas dej ua ke los saib xyuas kev ncaj ncees ntawm lub liner thiab tshawb xyuas qhov muaj peev xwm xau lossis ua txhaum cai. Cov tshuab no siv ntau yam thev naus laus zis xws li hluav taws xob conductivity sensors, kuaj lub tshuab nqus tsev, lossis kuaj ultrasonic txhawm rau txheeb xyuas qhov xau thaum ntxov thiab tiv thaiv dej poob lossis ib puag ncig.
