Xov xwm

Yas geogrid yog cov khoom siv polymer mesh nrog square lossis duab plaub uas tsim los ntawm kev ncab. Nws yog xuas nrig ntaus rau ntawm daim ntawv extruded polymer (feem ntau yog ua los ntawm polypropylene los yog high-density polyethylene) thiab tom qab ntawd raug rau kev taw qhia ncab hauv qab cua sov. Unidirectional stretching daim phiaj tsuas yog tsim los ntawm kev ncab raws qhov ntev ntawm daim ntawv, thaum biaxial stretching daim phiaj yog tsim los ntawm kev txuas ntxiv mus rau unidirectional stretching daim phiaj nyob rau hauv cov kev taw qhia perpendicular rau nws ntev. Biaxially stretched yas geogrid yog ua los ntawm polypropylene (PP) los yog polyethylene (PE) ua raw khoom, extruded los ntawm plasticization, xuas nrig ntaus, cua sov, longitudinal stretching, thiab transverse stretching.

Daim ntawv thov ntawm yas geogrid:
Geogrid yog cov khoom siv muaj zog geosynthetic. Siv dav hauv thaj chaw xws li embankments, tunnels, docks, highways, railways, thiab kev tsim kho.
Nws lub ntsiab siv yog raws li nram no:
1. Txhim kho txoj kev tsheb ciav hlau tuaj yeem faib cov khoom sib txawv, txhim kho kev ruaj ntseg thiab kev muaj peev xwm ntawm txoj kev tsheb, thiab txuas ntxiv nws lub neej kev pab cuam;
2. tuaj yeem tiv taus cov khoom sib hloov loj dua;
3. Tiv thaiv txoj kev deformation thiab tawg los ntawm kev poob ntawm cov ntaub ntawv hauv kev;
4. Txhim kho tus kheej muaj peev xwm ntawm cov khoom siv rov qab ntawm cov phab ntsa tuav, txo cov av siab ntawm cov phab ntsa tuav, txuag nqi, ncua lub neej kev pab cuam, thiab txo cov nqi tu;

5. Kev sib xyaw ua ke ntawm kev tsim kho ntawm cov tshuaj tsuag thauj tog rau nkoj ua vaj tse rau kev txhim kho txoj kab nqes tuaj yeem tsis tsuas yog txuag 30% -50% ntawm kev nqis peev, tab sis kuj txo lub sijhawm tsim kho los ntawm ntau tshaj ob zaug;
6. Ntxiv geogrids rau hauv txoj kev thiab txheej txheej ntawm txoj kev loj tuaj yeem txo qhov deflection, txo cov kab nrib pleb, ncua qhov tshwm sim ntawm cov kab nrib pleb los ntawm 3-9 zaug, thiab txo cov thickness ntawm cov txheej txheem los ntawm 36%;
7. Tsim nyog rau ntau yam av, tsis tas yuav tsum tau kuaj cov chaw taws teeb, txuag kev ua haujlwm thiab sijhawm;
8. Kev tsim kho yog yooj yim thiab ceev, uas tuaj yeem txo cov nqi tsim kho.
