ʻEkolu mau ʻano nui o nā geotextiles:
1. Geotextile ulana ʻole i kuʻi ʻia me ka nila
Wahi a ke ʻano o ka mea, hiki ke hoʻokaʻawale ʻia nā geotextiles i ulana ʻole ʻia me ka nila i nā geotextiles polyester a me nā geotextiles polypropylene; hiki ke hoʻokaʻawale ʻia hoʻi i nā geotextiles fiber lōʻihi a me nā geotextiles fiber pōkole. Hana ʻia ka geotextile i ulana ʻole ʻia me ka nila i ka polyester a i ʻole ka fiber polypropylene ma o ke ʻano acupuncture, ʻo ka kikoʻī maʻamau i hoʻohana ʻia he 100g/m2-1500g/m2, a ʻo ke kumu nui ka pale ʻana i ka pali o ka muliwai, ke kai, a me ka loko, ka kaohi ʻana i ke kahe a me ka hoʻopakele ulia pōpilikia, a pēlā aku. He mau ala kūpono kēia e mālama ai i ka wai a me ka lepo a pale i ka paipu ʻana ma o ka kānana hope. ʻO nā geotextiles fiber pōkole e pili ana i nā geotextiles i ulana ʻia me ka nila polyester a me nā geotextiles i ulana ʻia me ka nila polypropylene, ʻo ia mau mea ʻelua he mau geotextiles i ulana ʻole ʻia. Hōʻike ʻia lākou e ka maʻalahi maikaʻi, ke kūpaʻa waikawa a me ka alkali, ke kūpaʻa i ka palaho, ke kūpaʻa ʻelemakule, a me ke kūkulu kūpono. ʻO ka laulā o nā geotextiles fiber lōʻihi he 1-7m a me ke kaumaha o 100-800g/㎡; ua hana ʻia lākou me nā filaments polypropylene a polyester paha ikaika kiʻekiʻe, i hana ʻia me nā ʻano hana kūikawā, a he kūpaʻa i ka ʻaʻahu, kūpaʻa i ka pahū, a me ka ikaika tensile kiʻekiʻe.
2. Geotextile hui (lole ulana ʻole i kuʻi ʻia me ka nila + kiʻiʻoniʻoni PE)
Hana ʻia nā geotextiles composite ma ka hoʻohui ʻana i nā lole non-woven i ulana ʻia me ka nila polyester pōkole a me nā kiʻiʻoniʻoni PE, a ua māhele nui ʻia i: "hoʻokahi lole + hoʻokahi kiʻiʻoniʻoni" a me "ʻelua lole a hoʻokahi kiʻiʻoniʻoni". ʻO ke kumu nui o ka geotextile composite ka anti-seepage, kūpono no nā alahao, nā alaloa, nā tunnels, nā subway, nā kahua mokulele, a me nā papahana ʻē aʻe.
3. Nā geotextiles hui ʻole a ulana ʻia
Hana ʻia kēia ʻano geotextile me ka lole ulana ʻole i kuʻi ʻia me ka nila a me ka lole ulana plastik. Hoʻohana nui ʻia ia no ka hoʻoikaika ʻana i ke kahua a me nā pono hana ʻenekinia kumu no ka hoʻoponopono ʻana i ka coefficient permeability.
