Hoʻolauna a me nā koi kūkulu ʻana o ka pākeke wai sodium bentonite

ʻO ka uhi pale wai pehu he ʻano mea geosynthetic i hoʻohana kūikawā ʻia e pale aku i ka liki ʻana i loko o nā loko hana, nā ʻōpala lepo, nā hale kaʻa ma lalo o ka honua, nā māla kaupaku, nā loko wai, nā waihona ʻaila a me nā pā kemika. Hana ʻia ia me ka bentonite sodium pehu kiʻekiʻe i hoʻopiha ʻia ma waena o ka geotextile composite kūikawā a me nā lole i ulana ʻole ʻia. ʻO ka moena bentonite anti-seepage i hana ʻia e ke ʻano punching nila hiki ke hana i nā wahi fiber liʻiliʻi he nui. ʻAʻole hiki i nā ʻāpana Bentonite ke kahe i hoʻokahi ʻaoʻao. Ke hālāwai me ka wai, hoʻokumu ʻia kahi papa pale wai colloidal like a kiʻekiʻe i loko o ka moena.

Nā Hiʻohiʻona Huahana:

ʻO ka lakio hana-kumukūʻai kiʻekiʻe a he nui nā ʻano hana like ʻole. Hiki i ka laulā huahana ke piʻi i 6 mika, kahi e hoʻomaikaʻi nui ai i ka pono o ke kūkulu ʻana.

Ka laulā o ka noi a me nā kūlana noi: Kūpono no ka hoʻokele kūlanakauhale (Landfill), Mālama wai, palekana kaiapuni, loko hana a me ke kūkulu ʻana i ka wai ma lalo o ka honua a me nā papahana anti-seepage.

Nā koi kūkulu:

1, Ma mua o ke kūkulu ʻana i ka pale bentonite pale wai, pono e nānā ʻia ka papa kumu. Pono e hoʻopaʻa ʻia a palahalaha ka papa kumu, ʻaʻohe lua, wai, pōhaku, aʻa a me nā mea ʻoi ʻē aʻe.

2, I ka wā e lawelawe ai a me ke kūkulu ʻana i ka pale bentonite pale wai, pono e pale ʻia ka haʻalulu a me ka hopena i ka hiki, a pono e pale ʻia ke kūlou nui o ke kino o ka pale. ʻOi aku ka maikaʻi o ke kau ʻana i hoʻokahi manawa.

3, Ma GCL Ma hope o ke kau ʻana a me ka ʻae ʻana, pono e hoʻokō ʻia ka hana hoʻopiha i ka wā hikiwawe loa. Inā hui pū ʻia me HDPE, pono e hoʻopaʻa ʻia a hoʻopaʻa ʻia ka geomembrane i ka manawa kūpono e pale aku ai i ka pulu a haki paha i ka ua.

ʻO ke ʻano hana pale wai: ʻo ka bentonite ʻāpana sodium-based i koho ʻia no ka pale pale wai bentonite hiki ke hoʻonui ʻia ma mua o 24 mau manawa ke hōʻike ʻia i ka wai, e hana ana i kahi ʻōnaehana colloidal like me ka viscosity kiʻekiʻe a me ka pohō kānana haʻahaʻa. Ma lalo o ka palena o ʻelua papa o ka geotextile, loli ka bentonite mai ka hoʻonui ʻole ʻia i ka hoʻonui ʻana i ke kauoha, a ʻo ka hopena o ka hoʻonui mau ʻana o ka wai, ʻo ia ka lilo ʻana o ka papa bentonite i mea paʻa, no laila he hopena pale wai.
