Cov kev qhia tam sim no thiab cov lus qhia luv luv ntawm geosynthetics tau nthuav tawm hauv qab no.
Geotextiles yog cov ntaub ntawv txuas ntxiv ntawm cov xov paj, nonwoven, knitted lossis plooj-sib khi ua cov fibers lossis xov paj. Cov ntawv txheeb yog hloov tau thiab permeable thiab feem ntau muaj cov tsos ntawm daim ntaub. Geotextiles yog siv rau kev sib cais, pom, lim dej, txhawb nqa thiab yaig tswj kev thov.
Geogrids yog cov khoom siv geosynthetic uas muaj qhov qhib daim phiaj zoo li. Daim ntawv thov tseem ceeb rau geogrids yog qhov cuab lub zog ntawm av.
Geonets yog qhib daim phiaj zoo li cov khoom tsim los ntawm ob pawg ntawm coarse, parallel, extruded polymeric strands sib tshuam ntawm qhov tsis hloov sib luag. Lub network tsim cov ntawv ntim nrog cov kab hauv dav hlau uas siv los nqa cov kua dej sib npaug lossis roj ntws.
Geomembranes yog cov ntawv hloov pauv hloov txuas tau los ntawm ib lossis ntau cov ntaub ntawv hluavtaws. Lawv yog qhov tsis yooj yim thiab siv raws li cov kab xaum rau cov kua dej lossis roj ntim thiab thiab muaj cov vapor.
Geocomposites yog cov geosynthetics ua los ntawm kev sib txuas ntawm ob lossis ntau hom geosynthetic. Xws li: geotextile-geonet; geotextile-geogrid; geonetgeomembrane; lossis ib daim duab rau ntawm lub qhov txhab av. Prefabricated geocomposite lub qhov dej lossis qhov chaw ntim dej ntsug (PVDs) yog tsim los ntawm cov yas yas tso nrog ib puag ncig los ntawm lub taub lim geotextile.
Geosynthetic av nplaum hnab (GCLs) yog cov geocomposites uas yog prefabricated nrog bentonite av nplaum txheej feem ntau sib xyaw ua ke ntawm ib txheej sab saum toj thiab hauv qab geotextile los yog geotextile bentonite sib khi rau geomembrane lossis ib txheej ntawm geotextile. Geotextile-encased GCLs feem ntau stitched los yog rab koob dhau los ntawm cov tub ntxhais bentonite kom muaj cov nplai shear tsis kam. Thaum hydrated lawv zoo ua cov teeb meem rau cov kua lossis roj thiab feem ntau siv rau hauv cov khib nyiab liner daim ntaub ntawv feem ntau nyob rau hauv kev sib txuas nrog geomembrane.
Geopipes muaj perforated lossis solid-wall polymeric kav dej siv rau cov kua dej lossis kua roj (suav nrog cov roj av lossis roj sau rau hauv cov ntawv thov av pov tseg). Hauv qee qhov xwm txheej perforated yeeb nkab yog qhwv nrog lub taub lim geotextile.
Geocells yog cov tuab tuab, peb-seem kev sib txuas tsim los ntawm ib daim hlab ntawm polymeric ntawv. Cov pob txaij ua ke sib koom ua ke tsim cov qe sib txuas uas muaj nkag nrog av thiab qee zaum pob zeb ua ke. Hauv qee kis 0.5 m txog 1 m qhov dav dav ntawm polyolefin geogrids tau sib txuas ua ke nrog ntsug polymeric pas nrig siv los tsim cov txheej txheem sib sib zog nqus geocell hu ua geomattresses.
