Ka laulā o ka waiho ʻana i ka geomembrane composite

Hoʻoholo nui ʻia ka hana ola o ka geomembrane composite ma muli o ka mālama ʻia ʻana o ke kiʻi plastik i ka mālama ʻana i ka wai.Wahi a nā kūlana aupuni o ka Soviet Union, hiki i ka polyethylene film me ka mānoanoa o 0.2m a me kahi stabilizer no ka ʻenehana hydraulic hiki ke hana no 40 a 50 mau makahiki ma lalo o nā kūlana wai maʻemaʻe a me 30 a 40 mau makahiki ma lalo o nā kūlana wai.ʻO ka pā wai wai ʻo Zhoutou i ka mua he pā pā kumu, akā ma muli o ka hiolo ʻana o ka pā, ua wehe ʻia ka ʻaoʻao o luna o ka pā kumu.No ka mālama ʻana i ka hana o ka anti-seepage kiʻekiʻe, ua hoʻohui ʻia kahi pā anti-seepage inclined i ke kumu.E like me ka hōʻike palekana a me ka decomposition o ka Zhoutou Reservoir Dam, i mea e hoʻoponopono ai i ka leakage nāwaliwali o ka ʻili a me ka leaka ʻana o ke kumu wai i hoʻokumu ʻia e ka hoʻoneʻe ʻana o ka dam, nā kino kino ʻole e like me ka uhi ʻana o ka pale moe, ka hoʻoulu kaua ʻana a me ka hoʻoulu ʻana. ʻO ka paʻa ʻana i ka pale backfilling maikaʻi, a me ka paʻi kiʻekiʻe jet grouting impervious pā pā i apono ʻia ma ke ʻano o ka pale ʻana i ke aniani.
ʻO nā hiʻohiʻona o ka geomembrane composite: ʻO ka geomembrane composite he mea geomembrane i haku ʻia me ka kiʻiʻoniʻoni plastik ma ke ʻano he anti-seepage substrate a me ka lole nonwoven.ʻO kāna hana anti-seepage e pili ana i ka hana anti-seepage o ka kiʻiʻoniʻoni plastik.ʻO kāna hana hoʻopaʻapaʻa ʻo ia ka impermeability o ka kiʻiʻoniʻoni i hoʻopaʻa ʻia i ke ala leakage o ka pā honua mai ka wai, me ka pale ʻana i ke kaomi wai a me ka hoʻololi ʻana i ka deformation dam ma muli o kona ikaika tensile nui a me ka wikiwiki o ka lohi;ʻO ka lole ʻaʻole i ulana ʻia kekahi mea kemika o nā fiber polymer pōkole, i hana ʻia ma o ke kuʻi ʻana i ka nila a i ʻole ka hoʻopaʻa ʻana i ka wela, a he kiʻekiʻe ka tensile ikaika a me ka lohi.Ma hope o ka hoʻopili ʻia ʻana me nā kiʻiʻoniʻoni plastik, ʻaʻole ia e hoʻonui wale i ka ikaika tensile a me ka hoʻopaʻa ʻana o nā kiʻiʻoniʻoni plastik, akā hoʻonui pū nō hoʻi i ka coefficient friction o ke kahua kaua ma muli o nā kikoʻī koʻikoʻi o nā lole i ulana ʻole ʻia, he mea pono i ka paʻa o nā geomembranes composite. a me na papa huna.
No laila, lawa ke ola hana o ka geomembrane composite e hoʻokō i ke ola hana i noi ʻia no ka pale ʻana i ka wai.
Ua uhi ʻia ka paia i luna me ka geomembrane composite no ka pale ʻana i ka nalo, me ka ʻaoʻao haʻahaʻa ma hope o ka pā pale ʻana i ka ʻike ʻana a me ka ʻaoʻao o luna e piʻi i kahi kiʻekiʻe o 358.0m (0.97m kiʻekiʻe ma mua o ke kiʻekiʻe o ka wai kahe).
Kū'ē wela kiʻekiʻe, hana antifreeze maikaʻi.
I kēia manawa, ʻo nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no ka mālama ʻana i ka seepage ma ka home a me nā ʻāina ʻē e komo pū me ka polyvinyl chloride (PVC) a me ka polyethylene (PE), ʻo ia nā mea hiki ke hoʻololi i ka polymer me ka haʻahaʻa haʻahaʻa, ka lohi ikaika, a me ka hiki ke hoʻololi i ka deformation.
I ka manawa like, loaʻa iā lākou ke kūʻē maikaʻi i ka bacteria a me ka sensitization kemika, ʻaʻole makaʻu i ka waika, alkali, a me ka paʻakai paʻakai.
