Keʻokeʻo 100% polyester non-woven geotextile no ke kūkulu ʻana i ka pā alanui
ʻO ka wehewehe pōkole:
He nui nā pōmaikaʻi o nā geotextiles non-woven, e like me ka ventilation, filtration, insulation, absorption water, waterproof, retractable, maikaʻi, palupalu, māmā, elastic, hiki ke hoʻihoʻi ʻia, ʻaʻohe kuhikuhi o ka lole, kiʻekiʻe huahana, wikiwiki hana a me nā kumukūʻai haʻahaʻa. Eia kekahi, loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka pale ʻana i ka waimaka, ka hoʻokaʻawale ʻana a me ka hoʻokaʻawale ʻana, ka hoʻokaʻawale ʻana, ke kūpaʻa, ka hoʻoikaika a me nā hana ʻē aʻe, a me ka permeability maikaʻi loa a me ka hana kānana.

ʻO nā geotextiles ʻaʻole i ulana ʻia he mau mea geosynthetic wai-permeable i hana ʻia me nā fiber synthetic ma o ka neʻe ʻana a i ʻole ka ulana ʻana. Loaʻa iā ia ka kānana maikaʻi loa, ka hoʻokaʻawale ʻana, ka hoʻoikaika a me ka pale ʻana, ʻoiai ka ikaika tensile kiʻekiʻe, ka permeability maikaʻi, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa manuahi, ke kūpaʻa ʻelemakule, ke kūpaʻa corrosion. Hoʻohana nui ʻia nā geotextiles non-woven i nā papahana he nui, e like me nā alanui, nā alahao, nā embankments, earth-rock DAMS, nā mokulele, nā kahua haʻuki, a me nā mea ʻē aʻe, e hoʻoikaika i nā kumu nāwaliwali, ʻoiai ke pāʻani nei i ke kuleana o ka noho kaʻawale a me ka kānana. Eia kekahi, he mea kūpono ia no ka hoʻoikaika ʻana i ka backfill o nā pā paʻa, a i ʻole no ka heleuma ʻana i nā panela o nā pā paʻa, a me ke kūkulu ʻana i nā pā paʻa i uhi ʻia a i ʻole nā abutments.

1. Kiʻekiʻe ikaika: ma lalo o ka like gram ke kaumaha kiko'ī, ka tensile ikaika o ka lōʻihi siliki spunbonded needled nonwoven geotextiles ma na aoao a pau, ua oi aku mamua o ka mea e ae needled nonwovens, a ua oi aku ka ikaika tensile.
2. ʻO ka hana kolo maikaʻi: He hana kolo maikaʻi kēia geotextile, hiki ke mālama i ka hana paʻa i ka hoʻohana lōʻihi, a ʻaʻole maʻalahi i ka deformation.
3. ʻO ke kūpaʻa ʻino ʻana, ka pale ʻelemakule a me ka pale wela: lōʻihi ka siliki spunbonded needled nonwoven geotextile he maikaʻi loa ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa ʻelemakule a me ke kūpaʻa wela, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka ʻāina paʻakikī me ka pōʻino ʻole.
4. ʻO ka hana mālama mālama wai maikaʻi loa: hiki ke hoʻomalu maikaʻi ʻia kona mau pores e hoʻokō ai i kahi permeability, i kūpono i nā papahana e pono ai ke kāohi i ka kahe wai.
5. ʻO ka palekana o ke kaiapuni a paʻa, hoʻokele waiwai a maikaʻi hoʻi: ke hoʻohālikelike ʻia me nā mea kuʻuna, ʻoi aku ka maikaʻi o ka geotextile spunbonded siliki lōʻihi, hiki ke hana hou ʻia a hoʻohana hou ʻia, hoʻemi i ke kaumaha o ke kaiapuni, a me ke kūpaʻa kiʻekiʻe, hiki i ka hoʻolaha lōʻihi ke mālama i ka paʻa. hana, hoemi loa i na koina malama.
6. ʻO ka hana maʻalahi: hana maʻalahi, ʻaʻole pono i ka ʻenehana paʻakikī a me nā mea hana, mālama i ka manpower a me nā kumu waiwai, kūpono no nā papahana i ka wikiwiki.

Hoʻohana ʻia ma kahi o ke alaloa, alahao, dam, kahakai kahakai no ka hoʻoikaika ʻana, kānana, hoʻokaʻawale a me ka hoʻoheheʻe ʻana, ʻoi aku ka hoʻohana ʻia i nā pā paʻakai a me nā māla kanu ʻōpala. ʻO ka mea nui i ka kānana, hoʻoikaika a me ka hoʻokaʻawale.
