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 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 ka geosynthetics he geotextiles, geogrids, geogrids, geomembranes, geogrids, geo composites, bentonite moena, geological slopes, geo foam, etc. Ma nā noi ʻenekinia, hiki ke hoʻohana ʻia nā Geotextiles me ka geogrids, geomembranes, geogrids a me nā mea ʻē aʻe. nā mea hoʻohui honua.

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 fiber polyester ka maikaʻi o ke kino a me ka mechanical, ʻoi aku ka paʻakikī a me nā waiwai kolo, kahi kiʻekiʻe heheʻe, kiʻekiʻe wela ke kūpaʻa, kūʻokoʻa kūʻokoʻa, 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 hoʻoikaika mechanical (ke ala acupuncture, ke ʻano o ka hoʻopaʻa ʻana i ka wai), ke ʻano hoʻopaʻa paʻa (ke ala 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.
