Weiwo™ Engineering Qib Geogrid
Weiwo yog tsim los rau txoj kev loj heev
Raws li "txhim kho kev cuam tshuam" thiab "kev ntxhov siab dissipation" thev naus laus zis, peb muab ntau yam kev daws teeb meem ntawm geosynthetic, los ntawm cov av mos ntawm lub hauv paus kev txhawb nqa mus rau asphalt pavement tawg tiv thaiv, uas tuaj yeem txo tag nrho lub neej kev tu tus nqi txog li 40%.
Txhim kho cov kabmob muaj peev xwm ntawm lub hauv paus tsis muaj zog
Engineering Challenges:Thaum hla cov av nplaum lossis cov av ntub dej, qhov tsis tshua muaj CBR qhov tseem ceeb feem ntau ua rau kev sib haum xeeb tsis sib xws thiab kev ua haujlwm tsis zoo.
Lub Weiwo BX series bidirectional geogrid siv "Tensioned Membrane Effect" los hloov cov khoom ntsug rau hauv kab rov tav tensile stresses. Los ntawm cov neeg kho tshuab kev sib cuam tshuam ntawm geogrid thiab aggregate, thauj khoom faib tau zoo diffused, tiv thaiv kev txav mus rau sab nraud ntawm txoj kev.
- Ua kom cov kabmob muaj peev xwm ntau dua lossis sib npaug li 50%
- Txo crushed pob zeb txheej thickness los ntawm 30%
Tiv thaiv kom pom kev tawg hauv asphalt pavements
Txoj Haujlwm Sib Tw: Thaum lub sijhawm kev tsim kho txoj kev, cov kab nrib pleb hauv thawj txheej txheej tuaj yeem nthuav tawm sai sai, ua rau luv luv - lub sij hawm tsis ua hauj lwm ntawm qhov chaw uas nyuam qhuav ua tiav.
Peb siv siab -lub zog fiberglass geogrid ua ib qho kev ntxhov siab-absorbing txheej. Nws tsis tshua muaj siab tensile modulus dissipates kev ntxhov siab nyob rau hauv cov lus qhia tawg, inhibits longitudinal tawg txoj kev loj hlob, thiab txhim kho lub neej qaug zog ntawm asphalt nto txheej.
- Extens txij nkawm lub voj voog los ntawm 3-5 xyoos.
- Resistant rau kev tsim kho kub siab tshaj 200 degree.
Nce toj siab thiab txhawb nqa lub ntiaj teb tuav cov phab ntsa
Kev sib tw engineering: txwv qhov chaw nyob rau hauv roob kev loj; tsoos pob zeb tuav cov phab ntsa yog kim, qeeb los tsim, thiab muaj av qeeg tsis muaj zog.
Siv lub "quasi- zoo li qub creep zog" ntawm Weiwo UX series unidirectional geogrid. Lub geogrid anchors cov av nyob ntev mus, tsim ib tug saj zawg zog, ib tug qauv. Qhov no tsis tsuas yog txo cov av cheeb tsam uas yuav tsum tau tab sis kuj yoog mus rau qhov tsis sib haum xeeb.
- Txhawb kev txhawb nqa ntawm txoj kab nqes mus txog 90 degree.
- Txuag 40% ntawm cov nqi piv rau cov kev daws teeb meem ib txwm muaj.

Txoj kev geogrid txo cov nqi li cas?
Weiwo geogrids txo cov nqi feem ntau los ntawm Aggregate Optimization. Los ntawm kev muab lateral confinement mus rau lub hauv paus chav kawm, peb geogrids ua rau kom lub modulus ntawm lub aggregate txheej. Qhov no tso cai rau cov engineers txo qhov yuav tsum tau ua kom tuab ntawm cov pob zeb crushed los ntawm 30-40% yam tsis muaj peev xwm thauj khoom. Tsis tas li ntawd, nws txo qis qhov tob ntawm kev khawb thiab cov nqi thauj khoom, txo qis qhov project carbon footprint.
Dab tsi yog qhov txawv ntawm Biaxial (BX) thiab Uniaxial (UX) geogrids hauv kev tsim kho?
Qhov kev xaiv nyob ntawm qhov kev taw qhia ntawm lub load.
Biaxial Geogrids (BX):Tsim los muab lub zog nyob rau hauv ob qho tib si longitudinal thiab transverse cov lus qhia. Lawv zoo tagnrho rau subgrade stabilization thiab pavement reinforcement qhov twg cov tsheb thauj khoom raug faib thoob plaws qhov chaw.
Uniaxial Geogrids (UX):Tshwj xeeb engineered los lis high tensile loads nyob rau hauv ib qho kev taw qhia. Cov no feem ntau yog siv rau Reinforced Soil Slopes (RSS) thiab Mechanically Stabilized Earth (MSE) khaws cov phab ntsa, qhov twg cov kev ntxhov siab tseem ceeb los ntawm lub siab ntawm cov av loj.
Weiwo geogrids puas tuaj yeem tiv thaiv kev cuam tshuam ntawm asphalt overlays?
Yog lawm. Peb Weiwo-FG™ Pro (Fiberglass Geogrid) tau tsim tshwj xeeb rau lub hom phiaj no. Thaum muab tso rau ntawm qhov qub pavement thiab asphalt tshiab overlay, nws ua raws li Stress Absorbing Membrane Interlayer (SAMI). Nws lub siab tensile modulus thiab qis - elongation yam ntxwv tso cai rau nws cuam tshuam thiab dissipate cov kev ntxhov siab ntau los ntawm cov kab nrib pleb hauv qis dua, zoo ncua kev cuam tshuam kev tawg rau ntau xyoo.
Kuv yuav xaiv qhov loj aperture (qhib) rau kuv geogrid li cas?
Qhov luaj li cas ntawm aperture yuav tsum sib phim rau qhov Gradation ntawm Infill Material. Rau qhov ua tau zoo tshaj plaws, geogrid cia siab rau "Mechanical Interlock"- qhov twg cov khoom sib sau ua ke nyob rau hauv daim phiaj qhib. Raws li txoj cai dav dav engineering, D50 (qhov nruab nrab ntawm qhov loj me) ntawm qhov sib sau yuav tsum tau sib haum nrog lub qhov ntev ntawm qhov aperture kom ntseeg tau tias cov khoom raug kaw tsis yog tsuas yog zaum saum daim phiaj.
Lub neej tsim ntawm Weiwo geogrids nyob rau hauv ib puag ncig hnyav yog dab tsi?
Weiwo geogrids yog tsim los ntawm qib siab - qib polymers (PP, HDPE, lossis PET) nrog ntxiv UV stabilizers thiab Carbon Black. Lawv yog cov tshuaj inert thiab resistant rau lom degradation, nrog rau acidic los yog alkaline av tej yam kev mob (pH ntau yam 2-12). Raws li cov qauv kev tsim qauv, peb cov geogrids yog engineered rau lub neej kev pab cuam ntawm 50 mus rau 100 xyoo, tswj siab ntev-Term Design Strength (LTDS) thoob plaws lub sij hawm.
