ʻO Geosynthetics kahi ʻano mea hou o ka ʻenekinia geotechnical, hiki ke hana ʻia me nā polymers kūlohelohe a i hana ʻia e ke kanaka (plastic, fiber chemical, synthetic rubber, etc.) a waiho ʻia i loko, ma luna o ka ʻili a ma waena o nā papa lepo like ʻole e hoʻoikaika a pale i ka lepo.
I kēia manawa, ua hoʻohana nui ʻia nā Geotextiles i nā alanui, nā ala kaʻaahi, ka mālama ʻana i ka wai, ka mana uila, ke kūkulu ʻana, nā awa moana, nā mines, ka ʻoihana koa, ka mālama ʻana i ke kaiapuni a me nā kula ʻē aʻe.ʻO nā ʻano nui o nā geosynthetics he geotextiles, geogrids, geogrids, geomembranes, geogrids, geo composites, bentonite moena, geological slopes, geo foam, etc. mea hoohui geo.

I kēia manawa, ʻo nā mea maka o nā geotextiles ka nui o nā fibers synthetic, ʻo ka mea maʻamau i hoʻohana ʻia he polyester fibers a me polypropylene fibers, ukali ʻia e nā polyamide fibers a me nā polyvinyl acetal fibers.
ʻO ka polyester fiber ka maikaʻi o ke kino a me ka mechanical, ʻoi aku ka paʻakikī a me nā waiwai kolo, ka helu heheʻe kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka wā kahiko, ka ʻenehana hana makua a me ka māhele mākeke kiʻekiʻe.ʻO nā hemahema he hydrophobicity maikaʻi ʻole, maʻalahi e hōʻiliʻili i ka condensate no nā mea insulation thermal, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, maʻalahi e vitrify, hoʻemi ʻia ka ikaika, ka waika maikaʻi a me ke kūpaʻa alkali.
ʻOi aku ka maikaʻi o ka elasticity polypropylene fiber, a ʻoi aku ka maikaʻi o kona elasticity a me ke kūpaʻa ma mua o ka fiber polyester.ʻO ke kūpaʻa maikaʻi a me ka alkali, ke kūpaʻa ʻaʻahu, ka pale ʻana i ka mildew a me ke kūpaʻa haʻahaʻa haʻahaʻa;Loaʻa iā ia ka hydrophobicity maikaʻi a me ka absorption wai, a hiki ke hoʻololi i ka wai i ka ʻili o waho ma ke koʻi fiber.He liʻiliʻi ka density, he 66% wale nō o ka fiber polyester.Ma hope o nā manawa he nui o ka hoʻolālā ʻana, hiki ke loaʻa ka fiber denier maikaʻi me ka hoʻolālā paʻa a me ka hana kiʻekiʻe, a laila ma hope o ka hoʻoikaika ʻana i ke kaʻina hana, hiki ke ʻoi aku kona ikaika.ʻO ka hemahema ka pale wela kiʻekiʻe, kahi palupalu o 130 ~ 160 ℃, ke kūpaʻa māmā maikaʻi ʻole, maʻalahi ke hoʻoheheʻe ʻia i ka lā, akā hiki ke hoʻohui ʻia nā mea hoʻopili UV a me nā mea hoʻohui ʻē aʻe i mea e pale ai iā UV.
Ma waho aʻe o nā mea i luna, hiki ke hoʻohana ʻia nā fiber jute, polyethylene fibers, polylactic acid fibers, etc. i mea maka no nā geotextiles nonwoven.Ua komo mālie nā fiber kūlohelohe a me nā fiber kūikawā i nā ʻano noiʻi like ʻole o nā geotextiles.No ka laʻana, ua hoʻohana ʻia nā fiber maoli (jute, pulu niu, pulu pulupulu ʻohe, a me nā mea ʻē aʻe) i ka subgrade, drainage, pale pale, pale ʻana i ka lepo a me nā māla ʻē aʻe.
ʻAno Geotextile
ʻO Geotextile kahi ʻano geotextile permeable i hana ʻia me nā fiber polymer e ka paʻi wela, ka cementation a me ka ulana ʻana, ʻike ʻia hoʻi he geotextile, me ka ulana ʻana a me nā nonwovens.
ʻO nā huahana i ulana ʻia ʻo Geotextile e pili ana i ka ulana (ulana maʻemaʻe, ulana poepoe), ulana (ulana maʻemaʻe, twill), wili (wili ʻana, wili nila) a me nā kaʻina hana ʻē aʻe.
Hoʻokomo ʻia nā geotextiles nonwoven i nā kaʻina hana e like me ke ʻano hana hoʻoikaika mechanical (ʻano acupuncture, ke ʻano o ka hoʻopaʻa ʻana i ka wai), ke ʻano hoʻopaʻa kemika (ke ʻano hoʻoheheʻe ʻia, ke ʻano impregnation), ke ʻano hoʻoheheʻe wela wela (ke ala ʻōwili wela, ke ala wela wela), etc.
ʻO ka geotextile i ulana ʻia ka geotextile mua i hoʻokomo ʻia, akā aia nā palena o ke kumukūʻai kiʻekiʻe a me ka hana maikaʻi ʻole.I ka hopena o nā makahiki 1960, ua hoʻokomo ʻia nā geotextiles non-woven.I ka hoʻomaka ʻana o nā makahiki 1980, hoʻomaka ʻo Kina e hoʻohana i kēia mea i nā hui ʻenekinia.Me ka kaulana o ka nila punched nonwovens a me ka spunbonded nonwovens, ke kahua noi o ka nonwovens ua oi ākea ma mua o ka deformed geotextiles, a ua ulu wikiwiki.Ua ulu ʻo Kina i mea hana nui o Nonwovens ma ka honua, a ke neʻe mālie nei i kahi mea hana ikaika.
ʻO Geotextile kānana, irrigation, kaʻawale, hoʻoikaika, pale ʻana i ka seepage, pale ʻana i ka maʻi, ke kaumaha māmā, ka ikaika tensile kiʻekiʻe, ke komo maikaʻi a me ke kūpaʻa haʻahaʻa haʻahaʻa, ke kū anuanu, ke kūpaʻa ʻelemakule, ka pale ʻana i ka corrosion, flexibility a me nā mea ʻē aʻe, hoʻohana nui ʻia i nā ʻano āpau.ʻO ke ola o ka metropolis hana maikaʻi loa e hōʻike ana ʻaʻohe maʻi ʻē aʻe.
No ke aha e hoʻokō ʻia ai ka helu helu kikoʻī ma mua o ke kūkulu ʻana i ka geotextile?ʻAʻole maopopo ka nui o nā ʻenehana novice e pili ana i ka helu kikoʻī o nā geotextiles ma mua o ke kūkulu ʻana.Pili ia i ka ʻaelike hoʻolālā a me ke ʻano o ka ʻōlelo kumu.ʻO ka maʻamau, helu ʻia e like me ka ʻāpana.Pono ʻoe e makaʻala i ka pali.Pono ʻoe e hoʻonui iā ia me ka coefficient slope.
