Moena Geotechnical no ka pale ʻana i ke kahawai a me ka hoʻoheheʻe ʻana
Hōʻike huahana:
ʻO ka moena Geo textile kahi ʻano hou o ka mea geo synthetic i hana ʻia me ka hui pū ʻia a waiho ʻia o nā filament ʻino.Loaʻa iā ia ke kūpaʻa paʻa kiʻekiʻe, kiʻekiʻe kiʻekiʻe o ka wehe ʻana a loaʻa iā ia ka hōʻiliʻili wai a puni a me nā hana hoʻoheheʻe pae.ʻO ke ʻano he ʻekolu-dimensional geo membrane core me ka nila-punched perforated non-woven geo textiles ma nā ʻaoʻao ʻelua.Hoʻokahe wikiwiki ʻia ka wai o ka honua i ke kumu geo mesh ʻekolu a loaʻa iā ia kahi ʻōnaehana mālama pore ponoʻī, nāna e poloka i ka wai capillary ma lalo o nā haʻahaʻa kiʻekiʻe.He mea hoʻoikaika paʻa hoʻi ia.
Nā hiʻohiʻona huahana:
1. Kiekie puʻe kū'ē, kiʻekiʻe hamama puka mānoanoa, me nā mea a puni ka wai ohi a me ka paepae puka wai.
2. Ma hope o ka hoʻohui ʻia ʻana o ka moena geotextile me ka geotextile ʻole i ulana ʻia, hiki iā ia ke hōʻiliʻili i ka wai ua e komo ana ma o ka uhi uhi lepo a i ʻole ka wai i hoʻokuʻu ʻia mai ka pā ponoʻī ma lalo o ka uhi uhi paʻa i kanu ʻia, a hoʻohana i kāna hana hoʻoheheʻe kūʻokoʻa e hoʻokuʻu mai ka. geotextile moena sandwich papa ma ke ʻano hoʻonohonoho pono e like me nā koi ʻenekinia, me ka ʻole o ka hana ʻana i ka silting.No laila, hiki iā ia ke pale i ka pilikia e hoʻoheheʻe ʻia ma muli o ka saturation absorption wai o ka papa uhi lepo.
3. ʻAʻole hiki i ka moena Geomat ke hoʻokahe i ka wai wale nō, akā, hoʻokuʻu pū i ke kinoea methane i hana ʻia e ka fermentation ma ka lepo (ʻoi aku ka ʻōpala ʻōpala), kahi kūpono no ka noi ʻana i ka ʻāina.
4. ka moena geotechnical a me ka HDPE i hui pū ʻia, i ka manawa like hiki ke hana maikaʻi i ka pale ʻana i ka membrane HDPE mai ka puncture.

Hoʻohana nui ʻia ia i ka pale ʻana i ke kahawai seepage a me ka hoʻoheheʻe ʻana, ka hoʻoheheʻe alanui o nā ala kaʻa a me nā alaloa, hoʻohuli i ka kānana o ka mālama ʻana.
nā pā, ka hoʻoheheʻe ʻana a me ka pale ʻana i ka wai o nā hale ma lalo o ka honua, nā mea kanu hoʻomaʻemaʻe wai, nā ʻāina a me nā papahana ʻē aʻe.
