I roto i ngā kaupapa whakahaere turuturu—pērā i ngā mea e pā ana ki ngā hanganga o raro whenua, ngā roto horihori, me ngā whenua ururua—me pēhea te whakatau i te wero pumau o te turuturu me te whai hua me te pumau? Hei kaihanga motuhake i roto i te mara o te geosynthetics, kua whakamahia e Shandong Hongyue Environmental Engineering Co., Ltd. (e kiia nei i muri nei ko "Hongyue Environmental") tōna tohungatanga whānui ki ngā Geosynthetic Clay Liners (GCL) hei hanga i tētahi kawa hanga pakari me te paerewa pūtaiao. Mā roto i ngā mahi matua e whā—"te whakarite i te whenua raro, te tāutanga pūtaiao, te taunga tika, me te whakakī anō i te wā tika"—ka whakamahia katoatia e tēnei kawa ngā painga ahurei o ngā GCL, inā koa ko tō rātou kaha ki te "pupuhi ina pa ki te wai me te whakaora anō," ā, ka whakatūria he arai ārai wai kore e taea te uru mō te whānuitanga o ngā kaupapa hangarau.
Hipanga Tuatahi: Te Whakarite Pakari i te Papa Whenua—Te Whakatakoto i te Tūāpapa Maeneene, Pūmau hoki
Ko te kounga o te papa raro e whakatau tika ana i te whai huatanga o te tāutanga GCL. E whakanui ana te tīma hangarau o Hongyue Environmental me tino whakarite te mata o te papa raro i mua i te hanganga. Tuatahi, me whakakīkī me te whakataurite i te papa raro; ina koa, ko te ōwehenga papatahi (e tautuhia ana ko te ōwehenga o te hohonutanga mōrahi o tētahi poka ki tōna diameter iti rawa) kaua e neke ake i te 1:6, ā, me āta haere ngā nekehanga katoa, me te aukati rawa i te aroaro o ngā āhuatanga koi pērā i ngā koki tika. Tuarua, me pupuri te mata o te papa raro kia ma, me te tango rawa i ngā paru koi katoa—tae atu ki ngā pakiaka tarutaru, te kirikiri nui atu i te 10 mm te diameter, me ngā kongakonga pereki—kia kore ai e poka te paparanga papanga whatu o waho o te GCL i te wā tāutanga. I tua atu, ahakoa ka taea te tāuta i ngā GCL ki runga i ngā papa raro makuku, ka tino āraia te kohikohinga o te wai e tū ana ki runga i te mata; i ngā wā ka tūtaki ki te wai rere kāore e taea te whakahaere, me whakatinana ngā mahi hurihanga rangitahi i mua i te wā kia mau tonu ai te mata mahi i roto i te āhua pai.
Hipanga Tuarua: Tāutanga Paerewa me te Punga—Te Whakarite kia Mau, kia Haumaru hoki te Taunga
I te wā tāutanga, e taunaki ana a Hongyue Environmental kia tapahia tika ngā GCL kia rite ki ngā rahi o te kaupapa; ka taea te whakatakoto i ngā arai ki te taha whakararo, ki te taha roa rānei. I te wā hanga, ka wetekina te GCL ki runga i te papa raro kua whakaritea, ko te tikanga ka tū te paparanga papanga whatu ki te whenua, ā, ko te paparanga geotextile kore-whatu e anga ana ki runga. Hei whakarite kia piri te GCL me te papa raro, me whakamahi ngā pine punga me ngā whāriki motuhake hei whakamau; hei tāpiri, me taumaha ngā taha o te arai ki ngā putea onepu hei ārai i te nekenekehanga i puta mai i te hau. E whakanui ana ngā tohunga hangarau me tino tupato i te wā tāutanga. Kāore e whakaaetia kia taraiwa tika ngā mīhini taumaha ki runga i te mata o te paraikete. Me mau hu papatahi ngā kaimahi e hikoi ana i runga i te rauemi hei ārai i ngā mea koi kei wero i te kiriuhi ā-roto (mō ngā paraikete ā-wai kua whakakikoruatia ki te kiriuhi) te kino rānei i te paparanga geotextile o waho, ka whakararuraru i te tohatoha ōrite o te bentonite.
Hipanga 3: Te Maimoatanga Taupoki Ātaahua—Te Hanga i tētahi Paparanga Ārai-Wae Tonu
Ko te maimoatanga hononga te mea nui e whakatau ana i te angitu, i te korenga rānei o te pūnaha ā-roto katoa. E ai ki ngā whakaritenga hanga a Hongyue Environmental, me pupuri te whānui taupatupatu i waenga i ngā paraikete ā-wai tata ki te 25 cm ki te 30 cm te iti rawa. I roto i te rohe taupatupatu, me pania he paura bentonite maroke motuhake (he whakapiri bentonite rānei)—e whakaratohia ana e te kamupene—kia ōrite te whakamahinga. Ko te tere tono paerewa e whakahaerehia ana i te 0.4 kg/m² kia mōhio ai, ina pā ki te wai, ka hanga e te hononga he paparanga ā-wai tonu, matotoru, rite ki te tiēre. Hei hiri atu i ngā taupatupatu, ka taea te tāpiri i te paninga paura ki te rīpene ā-wai motuhake, kia kore ai e pakaru ia taipitopito, kia hanga ai he arai ā-roto tonu, kore e uru.
Hipanga 4: Te Whakakī Paparanga i te Wā Wā—Te Whakarato Tiakitanga Mō Te Wā Roa
Kia oti ngā paraikete ārai-wai te whakatakoto, me tīmata wawe tonu te hanga paparanga tiaki, te whakakī rānei i te oneone. Mā tēnei ka ārai i te maroke me te ngaro o te whai huatanga o ngā paraikete nā te roa o te pānga ki te hau, te pupuhi wawe rānei mēnā ka pāngia e te ua. E aro nui ana a Hongyue Environmental ki ngā whakaritenga kounga mō te oneone whakakī: me ārai te oneone kia kore rawa e uru ngā mea mārō—pērā i te kirikiri, i ngā kongakonga pereki rānei—he nui ake te rahi o te matūriki i te 10 mm. I te wā e hanga ana, me whakamahi te oneone ma, te onepu pai rānei mō te whakakī paparanga me te whakakīkī; me whakahaere te matotoru o ia paparanga i roto i te awhe mai i te 30 cm ki te 50 cm, ā, me eke te matotoru whakakīkī ki te 85% neke atu rānei. Ehara i te mea ka ārai noa tēnei tukanga i ngā paraikete ārai-wai mai i ngā kino ā-ringa o waho, engari ka whakamahia hoki te pēhanga e puta mai ana i te papatipu oneone hei whakarei ake i te pumau whānui o te paparanga kore-wai.
Mā te whakamahi i tēnei "Tikanga Hanga-Whā-Hipanga" paerewa, ka taea e ngā paraikete bentonite ātete-wai a Shandong Hongyue Environmental te whakaatu katoa i ō rātou painga matua: he ātete teitei ki te pēhanga wai (neke atu i te 1.0 MPa), he kaha whakaora-ake (ka taea te whakatika i ngā kapiti tae atu ki te 2 mm te rahi), me te ātete tawhito pai me ngā āhuatanga hoa-taiao. Mai i te hanga rauemi ki te aratohu hangarau i te papaanga, e whakapau kaha ana a Hongyue Environmental Protection ki te whakarato ki ngā kiritaki he otinga ārai-mimi kua whakauruhia, me te whakamahi i te tohungatanga ngaio me ngā tukanga pakari kia mau tonu ai te ātete-wai o ia kaupapa.
