Geosynthetics ke mofuta o mocha oa thepa ea boenjiniere ea geotechnical, e ka etsoang ka li-polymers tsa tlhaho kapa tse entsoeng ke motho (polasetiki, fiber ea lik'hemik'hale, rabara ea maiketsetso, joalo-joalo) ebe e kenngoa ka hare, ka holim'a metsi kapa pakeng tsa likarolo tse fapaneng tsa mobu ho matlafatsa kapa ho sireletsa mobu. mobu.
Hona joale, li-geotextiles li 'nile tsa sebelisoa haholo litseleng, liporong, ho boloka metsi, matla a motlakase, kaho, likoung tsa leoatle, merafong, indastering ea sesole, ts'ireletso ea tikoloho le masimo a mang. Mefuta e ka sehloohong ea li-geosynthetics e kenyelletsa li-geotextiles, li-geogrids, geogrids, geomembranes, geogrids, geo compposites, mats'e a bentonite, matsoapo a geological, foam ea geo, joalo-joalo Lits'ebetsong tsa boenjiniere, li-geotextile li ka sebelisoa li le mong kapa li kopantsoe le li-geogrids, geomembranes le tse ling, li-geogrids le tse ling. lisebelisoa tsa motsoako oa geo.

Hajoale, lisebelisoa tse tala tsa geotextiles haholo-holo ke likhoele tsa maiketsetso, tse sebelisoang haholo ke likhoele tsa polyester le likhoele tsa polypropylene, li lateloe ke likhoele tsa polyamide le likhoele tsa polyvinyl acetal.
Fibre ea polyester e na le thepa e ntle ea 'mele le ea mochini, ho tiea ho hoholo le thepa ea ho hahaba, sebaka se phahameng se qhibilihang, ho hanyetsa mocheso o phahameng, ho hanyetsa botsofali, theknoloji ea tlhahiso e holileng le karolo e phahameng ea mmaraka.

Polypropylene fiber e na le elasticity e ntle, 'me elasticity ea eona hang-hang le ho tiea ha eona ho molemo ho feta fiber ea polyester. Ho hanyetsa acid e ntle le alkali, ho hanyetsa ho apara, ho hanyetsa hlobo le ho hanyetsa mocheso o tlaase; E na le hydrophobicity e ntle le ho monya metsi, 'me e ka fetisetsa metsi bokaholimong ba kantle ho axis ea fiber.

Likhoele tsa tlhaho le likhoele tse khethehileng li kene butle butle likarolong tse fapaneng tsa ts'ebeliso ea li-geotextiles. Ka mohlala, likhoele tsa tlhaho (jute, coconut shell fiber, bamboo pulp fiber, joalo-joalo) li 'nile tsa sebelisoa ho fokotsa, ho ntša metsi, ho sireletsa libanka, ho thibela khoholeho ea mobu le masimo a mang.
Mofuta oa Geotextile
Geotextile ke mofuta oa geotextile o khonang ho kenella o entsoeng ka likhoele tsa polymer ka ho tobetsa ka ho chesa, samente le ho loha, tse tsejoang hape ka hore ke geotextile, ho kenyelletsa ho loha le li-nonwovens.
Lihlahisoa tse lohiloeng tsa Geotextile li kenyelletsa ho loha (ho loha ka mokhoa o hlakileng, ho loha ho pota-potileng), ho loha (ho loha ka mokhoa o hlakileng, ho loha), ho loha (ho loha ka warp, ho loha linale) le mekhoa e meng ea tlhahiso.
