Geotextile mālama alanuike kaʻina hana kau
1. Ka mālama ʻana, ka lawe ʻana a me ka lawelawe ʻana i nā geotextiles
Pono e pale ʻia nā ʻōwili geotextile mai ka hōʻino ʻia ma mua o ke kau ʻana. Pono e hoʻopili ʻia nā ʻōwili geotextile ma kahi i ʻole ai ka hōʻiliʻili wai, ʻaʻole pono e ʻoi aku ke kiʻekiʻe o ka puʻu ma mua o ʻehā mau ʻōwili, a hiki ke ʻike ʻia ka ʻāpana ʻike o ka ʻōwili. Pono e uhi ʻia nā ʻōwili geotextile me nā mea opaque e pale aku i ka ʻelemakule UV. I ka wā o ke kaʻina mālama ʻana, pono e mālama ʻia ka pono o ka lepili a me ka pono o ka ʻikepili.
Pono e pale ʻia nā Geotextiles mai ka pōʻino i ka wā o ka halihali ʻana, me ka halihali ʻana ma ka wahi mai ka mālama ʻana i nā mea a i ka hana.
Pono e hoʻoponopono ʻia nā geotextiles i hōʻino kino ʻia. ʻAʻole hiki ke hoʻohana ʻia nā geotextiles i ʻino loa. ʻAʻole ʻae ʻia ka hoʻohana ʻana i kekahi geotextile e pili ana me nā reagents kemika e liki ana ma kēia papahana.
2. Ke ʻano hana o ke kau ʻana i ka geotextile:
ʻŌwili lima; pono e pālahalaha ka ʻili o ka lole a pono e waiho ʻia ke ʻae ʻana no ka hoʻololi ʻana e like me ke kūpono.
ʻO ke kau ʻana o nā geotextiles filament a i ʻole nā geotextiles pōkole e hana pinepine ʻia ma o nā hui lap, humuhumu a me ka hoʻopili ʻana. ʻO ka laulā o ke humuhumu a me ka hoʻopili ʻana ma luna, a ʻo ka laulā overlap ma luna. Pono e hoʻopili ʻia a humuhumu ʻia paha nā geotextiles i hiki ke hōʻike ʻia no ka manawa lōʻihi.
Ka humuhumu ʻana o ka geotextile
Pono e hana mau ʻia nā humuhumu āpau (no ka laʻana, ʻaʻole ʻae ʻia ke humuhumu ʻana). Pono nā geotextiles e uhi ma ka liʻiliʻi he 150 mm ma mua o ka uhi ʻana. ʻO ka mamao humuhumu liʻiliʻi loa he 25 mm mai ka selvedge (ka lihi i hōʻike ʻia o ka mea).
ʻO nā humuhumu o nā geotextiles i humuhumu maikaʻi ʻia e komo pū me ke ʻano humuhumu kaulahao hoʻokahi laina a me ke ʻano kaulahao laka kaulahao. ʻO ke kaula i hoʻohana ʻia no ka humuhumu ʻana he mea resin me ka liʻiliʻi o ka tension ma mua o 60 N a me ke kūpaʻa kemika a me ke kūpaʻa UV e like a ʻoi aku paha i ko ka geotextile.
Pono e humuhumu hou ʻia kekahi "nila leakage" ma ka geotextile i humuhumu ʻia ma ka wahi i hoʻopilikia ʻia.
Pono e hana ʻia nā hana kūpono e pale aku i ka lepo, nā mea ʻāpana a i ʻole nā mea ʻē mai ke komo ʻana i ka geotextile ma hope o ke kau ʻana.
GeotextileHiki ke hoʻokaʻawale ʻia nā hono ʻūhā i nā hono ʻūhā maoli, nā humuhumu a i ʻole nā wili ʻia ma muli o ka ʻāina a me ka hana.
ʻO ka ʻokoʻa ma waena o ka geotextile anti-seepage a me ka geotextile seepage
Ke kahe ka wai mai ka papa lepo maikaʻi a i ka papa lepo ʻāʻī, ua wili ʻia ka geotextile me ka permeability kinoea maikaʻi a me ka permeability wai me ka polyester staple fiber e hele i ka wai, e lawe pono ana i nā ʻāpana lepo, ke one maikaʻi a me nā ʻiliʻili, a mālama i ka geolayer a me ka wai. Paʻa ka ʻenekinia.
ʻO ka geotextile anti-seepage mua he ʻano mea polymer chemical flexible, nona nā ʻano o ka hapa liʻiliʻi, elongation kiʻekiʻe, ʻano ikaika o ka deformation, ke kū'ē ʻana i ka corrosion, ke kū'ē ʻana i ka mahana haʻahaʻa a me ke kū'ē ʻana i ka hau maikaʻi.
ʻO ke ʻano hana mua, ʻo ia ka ʻoki ʻana o ke kahawai leakage o ka pā pōhaku honua e ka impermeability o ka ʻili plastik. Loaʻa i ka ʻili plastik ke kaomi wai, a me ka hoʻonui ʻana o ka ikaika tensile a me ka elongation, hiki ke hoʻohana ʻia no ka deformation o ka pā; he polymer nō hoʻi ia. ʻO ka kemika fiber pōkole, kahi e hoʻokō ai i ka ikaika tensile kiʻekiʻe a me ka elongation ma o ka punching nila a i ʻole ka sila wela, ʻaʻole wale e hoʻonui i ka ʻike plastik ma hope o ka hui ʻana.
Ma muli o ka ʻili o ka geotextile nonwoven he ʻoʻoleʻa, ʻo ka ikaika tensile a me ke kū'ē ʻana o ka puncture o ka ʻiliʻili ʻikepili e hoʻonui i ke coefficient friction o ka ʻili paʻi, he mea maikaʻi ia no ke kūpaʻa o ka geomembrane composite a me ka papa pale. Me ke kū'ē koʻikoʻi i ka bacterial corrosion a me ka kemika, ʻaʻole makaʻu i ka waikawa, alkali, paʻakai corrosion.
Hana: ikaika haki kiʻekiʻe, a hiki i ka 20KN/m, kū'ē i ke kolo a me ka pala. Hiki ke hoʻohana ʻia i ka mālama wai, ka pā wai, ke kūkulu ʻana i nā alaloa, ke kahua mokulele, ke kūkulu ʻana, ka palekana o ke kaiapuni a me nā papahana ʻē aʻe, a hiki ke hana i ke kuleana o ka kānana ʻana, ka hoʻokahe ʻana, ka hoʻokaʻawale ʻana, ka pale ʻana a me ka hoʻoikaika ʻana.
