Geotextile ulana ʻia
Wehewehe Pōkole:
- ʻO ka geotextile ulana he ʻano mea geosynthetic i hana ʻia ma ka ulana ʻana i ʻelua a ʻoi aku paha mau seti o nā olonā (a i ʻole nā filaments pālahalaha) e like me kekahi ʻano. Hoʻopili nā olonā warp a me nā olonā weft kekahi i kekahi e hana i kahi ʻano pūnaewele maʻamau. ʻO kēia ʻano, e like me ka lole ulana, he kūpaʻa kiʻekiʻe a me ke ʻano maʻamau.

- Nā ʻano hana
- Ikaika Kiʻekiʻe
- He kiʻekiʻe ka ikaika tensile o ka geotextile ulana, ʻoi aku hoʻi ma nā kuhikuhi warp a me weft, a hiki i kona ikaika ke hoʻokō i nā koi mechanical o nā papahana ʻenekinia like ʻole. No ka laʻana, i nā papahana mālama wai e like me nā dams a me nā cofferdams, hiki iā ia ke kū i ke kaomi wai a me ke kaomi honua a pale i ka luku ʻia ʻana o nā hale. Ma ke ʻano laulā, hiki i kona ikaika tensile ke hiki i ka pae o kekahi mau tausani Newtons no ka mika (kN/m).
- He maikaʻi loa nō hoʻi kāna hana kū'ē i ka haehae. Ke kau ʻia i ka ikaika haehae o waho, hiki i ke ʻano i ulana ʻia o nā olonā ke hoʻopuehu pono i ke kaumaha a hoʻemi i ke kiʻekiʻe o ka haehae ʻana.
- Paʻa maikaʻi
- Ma muli o kona ʻano ulana maʻamau, loaʻa i ka geotextile ulana ke kūpaʻa maikaʻi o ka dimensional. Ma lalo o nā kūlana kaiapuni like ʻole, e like me ka loli o ka mahana a me ka makū, ʻaʻole ia e maʻalahi ke hoʻololi. ʻO kēia ka mea e kūpono loa ai no nā papahana e pono ai ke ʻano lōʻihi a me ka mālama ʻana i ke kūlana, e like me nā papahana hoʻoikaika moena ballast railway, kahi e hiki ai iā ia ke pāʻani i kahi hana paʻa.
- Nā ʻano o nā poho
- ʻO ka nui o nā pore a me ka hoʻolaha ʻana o ka geotextile i ulana ʻia he ʻano maʻamau. Hiki ke hoʻoponopono ʻia ka porosity e like me ke kaʻina hana ulana a hiki ke hoʻomalu pono ʻia i loko o kahi pae. ʻO kēia ʻano pore maʻamau e hiki ai iā ia ke loaʻa ka hana kānana maikaʻi, e ʻae ana i ka wai e hele manuahi me ka pale ʻana i nā ʻāpana lepo mai ka lawe ʻia ʻana e ke kahe wai. No ka laʻana, i nā papahana palekana kahakai, hiki iā ia ke kānana i ka wai kai a pale i ka nalowale ʻana o ke one kai.

- ʻEnekinia Mālama Wai
- I loko o nā hale mālama wai e like me nā pā a me nā ʻauwai, hiki ke hoʻohana ʻia ka geotextile ulana e hoʻoikaika i ke kino o ka pā a me ke ʻauwai. Hiki iā ia ke hoʻoikaika i ke kūpaʻa anti-sliding o ka nui o ka lepo a pale i ke ʻauwai mai ka ulia ʻana a me nā pōʻino ʻē aʻe ma lalo o ka hana a ka holoi ʻana o ke kahe wai a me ke kaomi honua. I ka manawa like, ma ke ʻano he papa kānana, hiki iā ia ke pale i nā ʻāpana liʻiliʻi i loko o ke kino o ka pā mai ka holoi ʻia ʻana e ka seepage a hōʻoia i ke kūpaʻa seepage o ke kino o ka pā.
- I nā papahana uhi ʻauwai, hiki ke waiho ʻia ka geotextile i ulana ʻia ma waena o ka mea uhi a me ke kahua lepo e hana i kahi hana hoʻokaʻawale a me ka kānana, pale i ka mea uhi a hoʻolōʻihi i kona ola lawelawe.
- ʻEnekinia Alanui a me ke Kaʻahele
- I ke kūkulu ʻana i nā alaloa a me nā alahao ma lalo o ke kahua, hiki ke waiho ʻia ka geotextile ulana ma lalo a i ʻole ma ka pali o ke kahua. Hiki iā ia ke hoʻonui i ka hiki ke hāpai i ka papahele, hoʻolaha i ka ukana kaʻa i hoʻouna ʻia mai ka ʻili alanui a pale i ka hōʻino ʻia ʻana o ke kahua ma muli o ka noho like ʻole. I ka mālama ʻana i ke kahua lepo palupalu, hiki ke hoʻohana ʻia ka geotextile ulana me nā mea hoʻoikaika ʻē aʻe. No ka laʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoikaika i loko o ka pā paʻa honua i hoʻoikaika ʻia e hoʻomaikaʻi i ke kūpaʻa o ka pā paʻa.
- ʻEnekinia Kūkulu
- I ke ʻenekinia kahua o nā hale, hiki ke hoʻohana ʻia ka geotextile ulana e hoʻokaʻawale i ke kahua mai ka backfill a puni. Hiki iā ia ke pale i nā mea haumia i loko o ka backfill mai ka hōʻino ʻana i ke kahua a i ka manawa like e pale aku ai i ka hui ʻana o ka mea kahua a me ka backfill, e hōʻoiaʻiʻo ana i ka hiki ke hāpai a me ke kūpaʻa o ke kahua. I ka papahana pale wai o ka hale papaʻa, hiki ke hoʻohana ʻia ka geotextile ulana ma ke ʻano he mea kōkua, me ka hui pū ʻana me ka papa pale wai e hoʻonui i ka hopena pale wai.
