Geogrid yog cov khoom siv geosynthetic loj nrog cov khoom tshwj xeeb thiab kev ua tau zoo piv nrog lwm cov geosynthetics. Nws feem ntau yog siv los ua cov khoom siv ntxiv rau cov khoom siv hauv av los yog cov khoom siv ntxiv rau cov khoom sib xyaw.
Geogrids tau muab faib ua plaub pawg: yas geogrids, steel-yas geogrids, fiberglass geogrids thiab polyester warp-knitted polyester geogrids. Daim phiaj yog ib daim phiaj ob sab los yog daim phiaj peb-dimensional nrog ib qhov siab ua los ntawm polypropylene, polyvinyl chloride thiab lwm yam macromolecular polymers los ntawm thermoplastic los yog molding. Thaum siv hauv engineering engineering, nws yog hu ua geotechnical geogrid.
Yas Geogrid:
Cov yas geogrid yog ncab los ua ib lub xwmfab lossis lub voj voos polymer mesh, uas tuaj yeem ua tau uniaxially stretched thiab biaxially stretched raws li qhov sib txawv stretching cov lus qhia thaum lub sij hawm tsim khoom. Nws punches qhov ntawm cov ntawv extruded polymer (feem ntau polypropylene los yog high-density polyethylene), thiab tom qab ntawd ua cov kev taw qhia ncab hauv cov cua sov. Daim phiaj uniaxially stretched tsuas yog ua los ntawm ncab raws qhov ntev ntawm daim ntawv; daim phiaj biaxially stretched yog tsim los ntawm kev txuas ntxiv mus rau uniaxially stretched daim phiaj nyob rau hauv cov kev taw qhia perpendicular mus rau nws ntev.
Mining Gegorid:
Mining geogrid yog ib hom yas mesh rau underground thee mines. Nws yog ua los ntawm polypropylene ua cov khoom tseem ceeb. Tom qab raug kho nrog cov nplaim hluav taws kub nyhiab thiab siv tshuab antistatic, nws yog "ob npaug-kuj" yas mesh nrog rau tag nrho cov qauv tsim los ntawm biaxial stretching. Cov khoom yog yooj yim los tsim, tsis tshua muaj nqi, nyab xeeb thiab zoo nkauj.
Hlau yas geogrid:
Cov hlau yas geogrid yog ua los ntawm cov hlau muaj zog hlau (los yog lwm cov fibers), tshwj xeeb tshaj yog kho, thiab polyethylene (PE), thiab lwm yam additives yog ntxiv los ua kom nws muaj zog tensile sawb los ntawm extrusion, thiab saum npoo muaj ntxhib. Cov qauv siab, nws yog lub zog muaj zog siv zog geotextile. Los ntawm qhov no, ib txoj siv tawv yog woven los yog sandwiched ntawm ib qho kev ncua deb vertically thiab horizontally, thiab nws cov hlws ris yog tsim los ntawm welding nws junction nrog ib tug tshwj xeeb ntxiv dag zog rau kev sib raug zoo fusion vuam tshuab, uas yog ib tug reinforced geogrid.
Fiberglass Geogrid:
Fiberglass geogrid yog ua los ntawm cov iav fiber ntau thiab cov khoom siv mesh ua los ntawm cov txheej txheem weaving. Txhawm rau tiv thaiv cov iav fiber ntau thiab txhim kho kev ua haujlwm tag nrho, nws yog cov khoom siv geocomposite los ntawm txheej txheej txheej tshwj xeeb. Cov khoom tseem ceeb ntawm cov iav fiber ntau yog: silicon oxide, uas yog cov khoom siv tsis zoo. Nws lub cev thiab tshuaj lom neeg muaj zog ruaj khov, thiab nws muaj lub zog siab, siab modulus, siab hnav tsis kam thiab zoo heev txias, tsis muaj kev nkag mus ntev; thermal stability Kev ua haujlwm zoo; cov qauv mesh ua rau kev sib xyaw ua ke thiab kev txwv; txhim kho lub peev xwm thauj khoom ntawm asphalt sib tov. Vim hais tias qhov chaw yog coated nrog tshwj xeeb hloov asphalt, nws muaj dual composite zog, uas zoo heev txhim kho cov hnav tsis kam thiab shear peev xwm ntawm lub geogrid.
Polyester Geogrid:
Polyester geogrid siv high-strength polyester fiber ua raw khoom. Lub warp knitting directional qauv yog saws, thiab warp thiab weft yarns nyob rau hauv cov ntaub yog tsis khoov rau ib leeg. Cov kev sib tshuam yog khi thiab ua ke nrog cov muaj zog fiber ntau filaments los ua ib qho kev sib koom ua ke, muab kev ua si tag nrho rau nws cov khoom siv kho tshuab. High-strength polyester fiber warp-knitted geogrid Daim phiaj muaj lub zog tensile siab, me elongation quab yuam, lub zog tsim kua muag loj, me me sib txawv ntawm ntsug thiab kab rov tav lub zog, ultraviolet aging kuj, hnav tsis kam, corrosion kuj, lub teeb yuag, muaj zog interlocking quab yuam nrog av los yog gravel, thiab yog haum rau reinforcing av. shear resistance thiab reinforcement txhim khu kev ncaj ncees thiab load peev xwm ntawm cov av, thiab ua lub luag haujlwm tseem ceeb.
