ʻEkolu kumu nui o nā geotextiles:
1. Geotextile i ulana ʻole ʻia i ke kui
Wahi a ka mea, hiki ke hoʻokaʻawale ʻia nā geotextiles non-woven needle-punched i nā geotextiles polyester a me nā geotextiles polypropylene; Hiki ke hoʻokaʻawale ʻia lākou i nā geotextiles fiber lōʻihi a me nā geotextiles pōkole. ʻO ka geotextile non-woven needle i hana ʻia me ka polyester a i ʻole polypropylene fiber ma o ke ʻano acupuncture, ʻo ka mea maʻamau i hoʻohana ʻia ʻo 100g / m2-1500g / m2, a ʻo ke kumu nui ʻo ia ka pale ʻana i ka pali o ka muliwai, ke kai, a me ka lake embankment, ka hoʻomalu wai a me ka hoʻopakele pilikia, etc. ʻO nā geotextiles pulupulu pulupulu ka nui o nā geotextiles i hoʻopaʻa ʻia i ka nila a me nā geotextiles i hoʻopaʻa ʻia i ka nila polypropylene. Hōʻike ʻia lākou e ka hoʻololi maikaʻi, ka waikawa a me ke kūpaʻa alkali, ka pale ʻana i ka corrosion, ke kūpaʻa ʻelemakule, a me ka hana maʻalahi. He 1-7m ka laulā o nā geotextiles fiber lōʻihi a me ke kaumaha o 100-800g/㎡; hana ʻia lākou me ka polypropylene ikaika kiʻekiʻe a i ʻole polyester long fiber filaments, i hana ʻia me nā ʻenehana kūikawā, a me ka ʻaʻahu ʻana, pahū, a me ka ikaika tensile kiʻekiʻe.
2. Geotextile Composite (Ka lole i ulana ʻole ʻia i ke kui + kiʻi ʻoniʻoni PE)
Hana ʻia nā geotextiles ma ka hui ʻana i ka polyester short fiber needle-punched non-woven fabrics a me PE films, a ua māhele nui ʻia i: "hoʻokahi lole + hoʻokahi kiʻiʻoniʻoni" a me "ʻelua lole a me hoʻokahi kiʻiʻoniʻoni". ʻO ke kumu nui o ka geotextile composite he anti-seepage, kūpono no nā kaʻaahi, alaloa, tunnels, subways, airports, a me nā papahana ʻē aʻe.
3. ʻAʻole i ulana a ulana ʻia nā geotextiles
Ua haku ʻia kēia ʻano geotextile me ka lole i ulana ʻole ʻia a me ka lole i ulana ʻia. Hoʻohana nui ʻia ia no ka hoʻoikaika ʻana i ke kumu a me nā keʻena ʻenehana kumu no ka hoʻoponopono ʻana i ka coefficient permeability.
