ʻO ka geomembrane composite kahi mea anti-seepage geotextile i haku ʻia me ka kiʻiʻoniʻoni plastik e like me ka substrate anti-seepage a me ka lole i ulana ʻole ʻia. ʻO kāna hana anti-seepage ma muli o ka hana anti-seepage o ke kiʻiʻoniʻoni plastik. ʻO nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no nā noi anti-seepage ma ka home a me ka honua ka nui o ka polyvinyl chloride (PVC), polyethylene (PE), a me ka ethylene/vinyl acetate copolymer (EVA). He ʻano ia o ka polymer chemical flexible material me ka haʻahaʻa haʻahaʻa kikoʻī, ka hoʻonui ikaika, kiʻekiʻe adaptability i deformation, corrosion kū'ē, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka hau kū'ē maikaʻi.

Hoʻoholo nui ʻia ke ola lawelawe o nā geomembranes composite ma muli o ka nalowale ʻana o ke kiʻi ʻoniʻoni i kona mau waiwai anti-seepage a me ka wai. Wahi a nā kūlana aupuni Soviet, hiki i nā kiʻiʻoniʻoni polyethylene me ka mānoanoa o 0.2m a me nā stabilizer i hoʻohana ʻia i ka ʻenekinia wai hiki ke hana no 40-50 mau makahiki ma lalo o nā kūlana wai maʻemaʻe a me 30-40 mau makahiki ma lalo o nā kūlana wai. No laila, lawa ke ola lawelawe o ka geomembrane composite e hoʻokō i nā koi anti-seepage o ka dam.

Ka laulā o geomembrane
ʻO ka pā wai i ka mua he pā pā kumu, akā ma muli o ka hiolo ʻana o ka pā, ua hemo ka ʻaoʻao o luna o ka pā kumu. No ka hoʻoponopono ʻana i ka pilikia o ka anti-seepage kiʻekiʻe, ua hoʻohui mua ʻia kahi pā anti-seepage inclined. Wahi a ka loiloi palekana a me ka nānā ʻana o ka wai wai ʻo Zhoutou Reservoir, i mea e hoʻoponopono ai i ka leakage palupalu a me ka hoʻoheheʻe ʻana o ke kumu wai i hoʻokumu ʻia e ka nui o ka hili ʻana o ka wai, nā ana anti-seepage vertical e like me ka uhi ʻana o ka pale moe, ka hoʻopili ʻana i ka ʻili, ka hoʻoheheʻe ʻana a me ʻO ka pale lima hoʻopiha piha maikaʻi, a ua hāpai ʻia ka pā pāpaʻi anti-seepage kiʻekiʻe. Ua uhi ʻia ka pā kuʻekuʻe luna me ka geomembrane composite no ka anti-seepage, a pili i ka paia anti-seepage kūpaʻa ma lalo, a hiki i kahi kiʻekiʻe o 358.0m (0.97m ma luna o ka pae kiʻekiʻe o ka wai).
hana nui
1. Hoʻohui i nā hana anti-seepage a me nā hana hoʻoheheʻe, ʻoiai e loaʻa ana nā hana e like me ke kaʻawale a me ka hoʻoikaika ʻana.
2. Kiʻekiʻe composite ikaika, kiʻekiʻe peel ikaika, a kiʻekiʻe puncture kū'ē.
3. Ka ikaika hoʻoheheʻe wai, ka nui friction kiʻekiʻe, a me ka hoʻonui laina laina haʻahaʻa.
