Pehea e hoʻokaʻawale ai i waena o nā geotextiles non-woven, ulana a staple fiber needle-punched geotextiles

Loaʻa i nā geotextiles pōkole ka kānana maikaʻi, pale, hoʻoikaika a me nā hopena pale, ka ikaika tensile kiʻekiʻe, ka permeability maikaʻi, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa maloʻo, ka pale ʻana i ka wā kahiko, a me ka pale ʻana i ka corrosion.Hoʻokaʻawale ʻia nā geotextiles i nā geotextiles i ulana ʻia a me nā geotextiles ʻole.

ʻO nā geotextiles ʻaʻole i ulana ʻia: ʻO nā geotextiles i ulana ʻole ʻia i hana ʻia i nā filament a i ʻole nā ​​kaula pōkole i waiho ʻia i loko o kahi mesh ma o nā mea hana like ʻole a me nā ʻenehana.Ma hope o ka acupuncture a me nā ʻenehana ʻē aʻe, hoʻopili ʻia nā fibers like ʻole me kekahi, hoʻopaʻa ʻia kekahi i kekahi a hoʻopaʻa ʻia e hana i ka lole.Hana maʻamau ka lole palupalu, plump, paʻa, a ʻoʻoleʻa, i hiki ke hoʻokō i nā mānoanoa like ʻole e hoʻokō i nā koi noi.Hiki iā ia ke loaʻa i ka hiki ke hoʻololi i ka deformation maikaʻi, hiki ke hoʻokaʻawale i ka lepo maikaʻi, ka ʻili palupalu a me ka multi-void, ʻoi aku ka maikaʻi o ka friction coefficient, hiki ke hoʻonui i ka hiki ke hoʻopili ʻia o nā ʻāpana lepo, etc. .Wehe ʻia ke koena o ka wai, a palupalu ka helehelena a loaʻa iā ia ka mana mālama maikaʻi.Wahi a ka lōʻihi o ka filament, ua māhele ʻia i ka filament non-woven geotextile a i ʻole ka filament non-woven geotextile.Hiki iā lākou ke hana maikaʻi loa i ka kānana ʻana, ka hoʻopaʻa ʻana, ka hoʻoikaika ʻana, ka pale ʻana, a me nā mea ʻē aʻe.ʻOi aku ka kiʻekiʻe o ka ikaika tensile o ka filament ma mua o ka filament pōkole, hiki ke koho a hoʻohana ʻia e like me nā koi kikoʻī.

Geotextile i ulana ʻia (geotextile i hoʻoikaika ʻia): ua haku ʻia ka geotextile i ʻelua mau pūʻulu like ʻole (a i ʻole nā ​​wili palahalaha), kapa ʻia kekahi pūʻulu ma ka ʻaoʻao longitudinal o ka loom (ke kuhikuhi o ka hele ʻana o ka lole), a ʻo ka hui ʻē aʻe. kapa ʻia ʻo warp.Kapa ʻia kahi hoʻokomo ʻaoʻao i ka weft.Hoʻohana ʻia nā mea ulana ʻokoʻa a me nā ʻenehana no ka hoʻopili ʻana i ke kaula a me ka ulana i loko o kahi ʻano lole, hiki ke ulana ʻia i loko o ka mānoanoa like ʻole a me ka compactness e like me nā pae noi like ʻole.ʻO ka ikaika tensile ikaika (ʻoi aku ka lōʻihi ma mua o ka latitu), me ke kūpaʻa maikaʻi loa.Hoʻokaʻawale ʻia nā geotextiles i ulana ʻia i ʻelua mau ʻāpana: geotextiles hoʻoikaika ʻia a me nā geotextiles i hoʻoikaika ʻole ʻia e pili ana i ka ʻenehana ulana a me ka hoʻohana ʻana i ka warp a me ka weft.ʻOi aku ka ikaika o nā geotextiles i hoʻoikaika ʻia ma mua o nā geotextiles maʻamau.Hoʻohana mau ʻia nā geotextiles i ulana ʻia i ka hana a manaʻo ʻia e hoʻoikaika ʻia no nā papahana geotechnical.ʻO ka hana nui ka hoʻoikaika a me ka hoʻoikaika ʻana, a iā ia ka hana o ka pale mokulele a me ka mālama.ʻAʻole ia he hana o ka hoʻokahe mokulele a hiki ke koho ʻia e like me ke kumu noi kikoʻī.

ʻO ka geotextile i hoʻopaʻa ʻia i ka nila: kahi ʻano ulana kūpono a hewa ʻole a me nā lole ʻoihana.Hana ʻia ia me ka polyester bent staple fibers me ka fiber fineness o 6-12 denier a me ka lōʻihi o 54-64 mm e like me ka mea maka.Ma hope o ke kaʻina hana o ka wehe ʻana, ka hoʻopau ʻana, ka hoʻopaʻa ʻana (hoʻopili ʻia nā kaula pōkole me kekahi), ka waiho ʻana (ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana), ka kui kui a me nā ʻenehana hana ʻē aʻe o nā lako hana ʻole i ulana ʻia, hana ʻia i lole.Hoʻohana nui ʻia ia i ka hoʻoikaika ʻana i nā subgrades o ke kaʻaahi, ka mālama ʻana i nā paepae alanui, ka pale ʻana i nā keʻena haʻuki a me nā dikes, nā pale o ka hana hydraulic, tunnels, mudflats kahakai, reclamation, mālama kaiapuni a me nā papahana ʻē aʻe.
