Hongyue tri-dimension composite geonet no ka hoʻoheheʻe wai
ʻO ka wehewehe pōkole:
He ʻano ʻano mea geosynthetic hou ʻo ka ʻupena geodrainage composite thri-dimensional. ʻO ke ʻano o ka haku mele he ʻekolu-dimensional geomesh core, ua hoʻopili ʻia nā ʻaoʻao ʻelua me nā geotextiles non-woven. Aia ka 3D geonet core i kahi iwi ʻaoʻao mānoanoa a me ka iwi ʻaoʻao diagonal ma luna a me lalo. Hiki ke hoʻokuʻu koke ʻia ka wai lepo mai ke alanui, a he ʻōnaehana mālama pore e hiki ke ālai i ka wai capillary ma lalo o nā haʻahaʻa kiʻekiʻe. I ka manawa like, hiki iā ia ke pāʻani i ka hana kaʻawale a me ka hoʻoikaika paʻa.

ʻO ka palekana a me ke ola lawelawe o ke kaʻaahi, ke ala nui a me nā ʻoihana ʻoihana ʻē aʻe e pili ana i kā lākou ʻōnaehana hoʻokaʻawale, kahi mea nui o nā geosynthetic i ka ʻōnaehana wai. ʻO ke ʻano o ka wai hoʻoheheʻe ʻekolu-dimension he ʻano hou o ka geosynthetic material, ʻekolu-dimensional composite drainage network he ʻano hou o ka geosynthetic material, ʻekolu-dimensional composite drainage network. ʻEkolu-dimensional composite geodrainage network he ʻekolu-dimensional structure of plastic mesh double-sided permeable geotextile, hiki ke hoʻololi i ke one kuʻuna a me ka ʻiliʻili papa, ka mea i hoʻohana nui ʻia no ka pae ʻāina, alanui a me ka tunnel i loko o ka pā.
Nā hiʻohiʻona huahana
Hana ʻia ka geonet composite tri-dimension no ka hoʻokahe ʻana i kahi geonet ʻekolu-dimension i uhi ʻia me ka geotextile ma nā ʻaoʻao ʻelua. Loaʻa iā ia ka waiwai o ka geotextile (filtration) a me ka geonet (drainage a me ka pale) a hāʻawi i kahi ʻōnaehana hana o "filtration-drainage-protection". Hiki i ka hana tri-dimension ke halihali i ka ukana kiʻekiʻe i ke kūkulu ʻana a hoʻomau i kekahi mānoanoa, ikaika a maikaʻi hoʻi i ka conductivity wai.
Lai o ka noi
Hoʻokahe ʻāina; ʻO ka lalo o ke alanui a me ka hoʻoheheʻe pavement; ʻO ka hoʻoikaika ʻana i ka hoʻoheheʻe ʻana i ka lepo palupalu; ʻO ka hoʻoheheʻe ʻana o ke kaʻaahi subgrade, ka ʻauʻau ʻana o ke alahao a me ka hoʻoheheʻe ʻana o ke kaʻaahi, ka ʻauwai tunnel; Ka hoʻoheheʻe ʻana o ka hale lalo; Ka paʻa ʻana o ka pā i hope o ka wai; ʻO nā kīhāpai a me nā pā pāʻani wai.
