Nā pākeke pale wai ʻole Bentonite / nā moena pale wai ʻole
Wehewehe Pōkole:
I. Nā Kikoʻī Huahana: Nui o ka ʻāpana ≥ 4000g/㎡, laulā 4-6m.
II. Nā ʻano hana
Ke hoʻohālikelike ʻia me nā liners pālolo i hoʻopaʻa ʻia, he mau pono kona e like me ka liʻiliʻi o ka nui, ke kaumaha māmā, ka maʻalahi o ka loli, ka hana density maikaʻi, ka ikaika shear kiʻekiʻe, ke kūkulu maʻalahi, a me ka hiki ke hoʻololi i ka hoʻonohonoho ʻana ʻaʻole like.
ʻO ka inoa mineralogical no ka bentonite ʻo montmorillonite. Ua māhele nui ʻia ka bentonite kūlohelohe i ʻelua mau māhele e like me kona ʻano kemika: sodium-based a me calcium-based. Loaʻa iā Bentonite ke ʻano o ka pehu ʻana i ka wā e pili ai me ka wai. Ma ke ʻano laulā, hoʻonui ka bentonite calcium-based i ʻekolu manawa wale nō o kona nui ponoʻī ke pehu, ʻoiai ʻo ka bentonite sodium-based e omo i ʻelima manawa o kona kaumaha ponoʻī i ka wai, e hoʻonui ana i ʻoi aku ma mua o 15-17 mau manawa o kona nui mua. ʻO ka laka ʻana i ka bentonite sodium-based ma waena o ʻelua mau papa o ka mea geosynthetic e hāʻawi i ka pale a me ka hoʻoikaika ʻana, e hāʻawi ana i ka GCL i kahi ikaika shear holoʻokoʻa.
III. Hoʻohana Huahana
ʻO nā pale wai ʻole o Benton he mau mea geosynthetic i hoʻolālā kūikawā ʻia no ka pale ʻana i ke kahe ʻana o ka wai i loko o nā loko hana a me nā hiʻohiʻona wai, nā ʻōpala lepo, nā hale kaʻa ma lalo o ka honua, nā māla ma luna o ka hale, nā loko wai, nā waihona ʻaila, a me nā wahi mālama kemika. Loaʻa iā lākou ka bentonite sodium-based ākea i hoʻopiha ʻia ma waena o ka geotextile composite i hana kūikawā ʻia a me ka lole i ulana ʻole ʻia. ʻO ka moena pale wai bentonite, i hana ʻia me ka hoʻohana ʻana i ke ʻano kuʻi nila, hana i nā wahi fiber liʻiliʻi he nui, e pale ana i nā ʻāpana bentonite mai ke kahe ʻana i hoʻokahi ʻaoʻao. I ka wā e pili ai me ka wai, hana ia i kahi papa pale wai like, e like me ka gel kiʻekiʻe i loko o ka moena, e pale pono ana i ka liki ʻana o ka wai.
