Paraikete ārai wai Bentonite/whāriki ārai wai
I. Ngā Whakatakotoranga Hua: Papatipu horahanga ≥ 4000g/㎡, whānui 4-6m.
II. Ngā Āhuatanga Mahi
Ki te whakatauritea ki ngā arai uku kua whakakīia, he maha ngā painga pēnei i te iti o te rōrahi, te mama, te ngāwari, te mātotoru pai, te kaha kutikuti teitei, te hanga māmā, me te ngāwari ki te taunga kore taurite.
Ko te ingoa kohuke mō te bentonite ko montmorillonite. E rua ngā wāhanga matua o te bentonite tūturu, arā, ko te konutai me te konupūmā. Ko te āhuatanga o te bentonite ko te pupuhi ina pā ki te wai. I te nuinga o te wā, ka piki te bentonite konupūmā ki te toru noa iho ngā wā o tōna ake rahinga ina pupuhi, ko te bentonite konutai ia ka mimiti i te rima ngā wā o tōna ake taumaha ki roto i te wai, ka piki ki te neke atu i te 15-17 ngā wā o tōna ake rahinga taketake. Mā te here i te bentonite konutai i waenganui i ngā paparanga e rua o te rauemi geosynthetic ka tiakina, ka whakakaha hoki, ka hoatu ki te GCL he kaha kutikuti whānui.
III. Te Whakamahinga o te Hua
Ko ngā paraikete ārai wai o Benton he rauemi geosynthetic i hangaia mō te ārai i te turuturu i roto i ngā roto horihori me ngā āhuatanga wai, ngā whenua ururua, ngā karāti raro whenua, ngā māra tuanui, ngā puna kaukau, ngā putunga hinu, me ngā wāhi rokiroki matū. He bentonite konutai nui rawa atu ēnei, kua whakakīia ki waenganui i ngā geotextile hiato motuhake me te papanga kore-whatu. Ko te whāriki ārai wai bentonite, i hangaia mā te whakamahi i te tikanga wero ngira, ka hanga he maha ngā āputa muka iti, ka ārai i ngā matūriki bentonite kei rere i te taha kotahi. Ina pā ki te wai, ka hanga he paparanga ārai wai rite tonu, he rite ki te tiēre teitei te matotoru i roto i te whāriki, ka ārai pai i te turuturu wai.
