Khoom Description
2 meter Peb -D Composite Drainage Netyog siv nyob rau hauv railway, kev loj, qhov, municipal engineering, reservoir, txoj kab nqes tiv thaiv thiab lwm yam dej tej yaam num.
Khoom nta: Cov kua dej zoo, siab tensile zog. Txo qhov tshwm sim ntawm geotextile embedment nyob rau hauv lub mesh core, thiab tuav ntev - lub sij hawm ruaj khov kua. Ntev -lub sij hawm siab load (tuaj yeem tiv taus compression load li ntawm 3000Ka). Corrosion kuj, acid thiab alkali tsis kam, kev pab lub neej ntev. Kev tsim kho yog yooj yim, txo lub sijhawm tsim kho, txo kev nqis peev.

Lub luag haujlwm tseem ceeb ntawm hdpe geonet siv2 meter Peb -D Composite Drainage Net
1. Cov nyhuv dej ntws: tso rau ntawm lub hauv paus, siv los tso cov dej tawm ntawm qhov muab tub lim thiab lub hauv paus, thaiv cov dej capillary thiab ua kom zoo sib xyaw ua ke rau hauv ntug dej. Cov qauv zoo li no cia li ua kom luv luv ntawm txoj kev ntws ntawm lub hauv paus, thiab lub sij hawm tso dej yog luv heev, uas tuaj yeem tiv thaiv cov liquefaction ntawm txoj kab nqes av thiab txhim khu kev ruaj ntseg ntawm txoj kab nqes.
2. Tom qab sib xyaw geodrainage network thiab tsis yog -woven geotextiles tau ua ke, nyob rau hauv lub faus kaw txheej txheej, cov dej nag uas permeates cov av npog txheej los yog cov dej phwj tawm los ntawm cov chaw cia khoom nws tus kheej tuaj yeem sau thiab txiav tawm los ntawm cov txheej txheem ntawm cov av lev raws li kev tsim kho engineering los ntawm kev siv nws cov kua dej tshwj xeeb, tsis muaj kev tsim.
3. Cov nyhuv cais tawm: cov geotextile ntawm kev sib xyaw geodrainage network tuaj yeem tiv thaiv kev sib xyaw ntawm cov muab tub lim thiab cov khoom siv hauv av.
4. Geotextiles nrog lim muaj nuj nqi tuaj yeem tiv thaiv cov khoom tsis zoo los ntawm kev nkag mus rau hauv cov tub ntxhais qhov sib txawv, thiaj li ua kom lub sijhawm ntev - ua haujlwm tau zoo ntawm cov tub ntxhais cov dej ntws.
Cov khoom siv
A 2 meter Peb -D Composite Drainage Netyog ib qho tseem ceeb geosynthetic cov ntaub ntawv nyob rau hauv niaj hnub landfill engineering, tshwj xeeb tshaj yog tsim los muab siab -kua dej thaum integrating pom thiab tiv thaiv functions. Cov khoom no feem ntau muaj peb -dimensionalgeonetcore, tsim los ntawm cov tawv HDPE polymers, uas yog thermally bonded rau ib los yog ob tug uas tsis yog -wovengeotextilentaub. Qhov kev sib xyaw ua ke no tsim txhua yam - hauv - ib qhosib xyawsystem uas muab superior hydraulic conductivity, pom, thiab av sib cais.
Hauv qhov chaw pov tseg qhov tseem ceeblinersystem, uaComposite Drainage Geonetplays lub luag haujlwm tseem ceeb uas yogleachatetxheej txheej. Tus qauv configuration, los ntawm hauv qab mus rau sab saum toj, yog raws li nram no: ua ntej, ib tug compacted av nplaumlinertsim lub hauv paus. Saum toj no, ib tug dugeomembrane-feem ntau yog 1.5mm mus rau 2.0mm tuab HDPE daim ntawv- yog siv los ua thawj impermeable barrier los tiv thaivleachatetsiv mus nyob rau hauv lub subsoil. CovComposite Drainage Geonetyog ntsia ncaj qha rau saum qhov nogeomembrane. Covgeotextilesab ntawmsib xyawntsej muag, tiv thaiv qhov muag heevgeomembranelos ntawm puncture thaum lub sij hawm installation thiab los ntawm ntev - lub sij hawm puas. Qhov qhib, peb -dimensionalgeonetcore muab txoj hauv kev muaj zog rau kev thauj mus los saileachate, nrog rau siab heev hauv - dav hlau transmissivity, feem ntau tshaj5 x 10⁻⁴ m²/s, txawm nyob rau hauv qhov loj heev compressive loads overlying pov tseg.
Kev sib caisgeotextileyog ces muab tso rau saum lubgeonet. Cov ntaub no ua raws li lub lim dej, tiv thaiv cov khoom zoo los ntawm cov khoom pov tseg los ntawm clogging cov tub ntxhais cov kua dej, yog li tswj nws lub peev xwm hydraulic hla qhov chaw pov tseg tag nrho lub neej ua haujlwm. Qhov no synergistic system -geomembranerau kev tuav pov hwm,geonetrau dej ntws, thiabgeotextilerau kev pom thiab kev tiv thaiv- xyuas kom muaj kev sau zoo thiab tshem tawmleachate, tiv thaiv ib puag ncig ib puag ncig los ntawm kev sib kis.2 meter Peb -D Composite Drainage Net
