Geomembrane I ēnei rā, me te aro nui ki te tiaki taiao, kua noho te whakahaere me te whakarerekētanga o ngā puranga paru hei wāhanga nui o te whanaketanga pumau o ngā tāone. I roto i ēnei, ko te whakamahinga o ngā geomembrane, inā koa i roto i te whakatakotoranga o ngā puranga paru me te hanganga o ngā pūnaha whakawhiti wai ua me te paru, ehara i te mea ka whakapai ake i te mahi ārai-mimi o ngā puranga paru, engari ka tino whakatairanga hoki i te kohikohinga o te wai ua me te wehe i te paru, ka tutuki ai te whai huatanga o ngā rauemi. Ko ngā whāinga rua o te whakamahinga nui me te tiaki taiao. Ka matapakihia hohonutia e tēnei tuhinga ngā taipitopito hangarau, ngā āhuatanga whakahaere me ngā painga taiao o te whakatakotoranga o ngā geomembrane ki roto i ngā puranga paru me te hanganga o ngā kiriuhi hipoki whakawhiti wai ua me te paru.
Tuatahi. Te hiranga o te geomembrane i roto i te whakatakotoranga o ngā putunga para. He mea nui te geomembrane, he rauemi hangai polymer, i roto i te hanganga putunga para nā te mea he pai te mahi ārai-mimi, he pai ngā āhuatanga ā-tinana me te ā-mīhini, me te pumau matū. Ka taea e ia te aukati i te urunga o te wai para ki roto i te wai whenua me te oneone, te whakaiti i te tūponotanga o te parahanga wai whenua, me te tiaki i te taiao taiao e karapoti ana. I taua wā anō, he kaha kume me te roa o te geomembrane, ā, ka taea te tu atu i te pēhanga me te whakarerekētanga i puta i te wā o te tukanga putunga para, kia mau ai te mahi pumau o te putunga para mō te wā roa.
Ngā whakaritenga mō te whakatakoto geomembrane ki te puranga paru
1. Te arotake me te hoahoa o te papaanga: I mua i te whakatakotoranga, me whakahaere he arotake taipitopito o te papaanga o te puranga paru, me te mārama ki ngā āhuatanga whenua me ngā āhuatanga wai, me te hoahoa i tētahi kaupapa pūnaha ārai-mimi e tika ana i runga i te āhuatanga tūturu. Tae atu ki te whakatau i te momo, te matotoru, te taumata whakatakotoranga me te momo hononga o te geomembrane, me ētahi atu.
2. Te Maimoatanga o te Tūāpapa: Me whakarite kia papatahi te tūāpapa i te wāhi whakatakotoranga, ā, kia kore he mea koi, ā, ki te tika, kia whakakīkītia, kia whakatakotoria rānei he urunga onepu hei tautoko pai, hei tiaki hoki i te geomembrane mai i te kino.
3. Te whakarite rauemi me ngā taputapu: tīpakohia ngā rauemi geomembrane e tutuki ana i ngā paerewa, ā, tirohia te kounga o ō rātou āhua, ō rātou āhuatanga ā-tinana me ā-pūkaha me ētahi atu tohu; I taua wā anō, whakaritea ngā taputapu mīhini e hiahiatia ana, ngā taputapu whakarewa, ngā taputapu whakamātautau, me ētahi atu mea mō te whakatakotoranga.
Tuatahi. Te hangarau whakatakotoranga me te whakarewa geomembrane
1. Tikanga whakatakoto: Ko te tikanga whakatakoto hurihuri te tikanga e whakamahia ana, arā, ka haria tuatahitia te geomembrane ki te wāhi whakatakoto i roto i ngā rōra, kātahi ka wherahia i te ahunga kua whakaritea, ka pēhia i te wā e whakatakoto ana kia maeneene te mata o te membrane, kia kore he kita, kia iri hoki. I te wā e whakatakoto ana, me aro ki te ahunga o te rauemi membrane. Ko te tikanga, ka whakatakotoria i te taha o te pari o te puranga paru hei whakaiti i te paheke.
2. Hangarau whakarewa: Ko te hononga i waenga i ngā geomembranes ka whakamahi i te whakarewa wera rewa, te whakarewa whakaputa rānei hei whakarite i te kounga o te whakarewa. I mua i te whakarewa, horoia te mata o te membrane hei tango i ngā poke pēnei i te hinu me te makuku; I te wā o te whakarewa, ka tino whakahaerehia te pāmahana, te pēhanga me te wā kia pakari ai te whakarewa me te hiri pai. I muri i te otinga o te whakarewa, me tirotiro te kounga o te whakarewa, tae atu ki te tirotiro tirohanga, te tirotiro pēhanga hau, te tirotiro mura hiko rānei, me ētahi atu, kia kore ai he whakarewa ngaro, he whakarewa mariko rānei.
Ahua. Te hanga kiriata hipoki mō te wai ua me te paru
Ko te whakatakoto i tētahi kiriata hipoki ki runga ake i te puranga paru tētahi o ngā mahi matua hei whakatutuki i te whakawhiti i te wai ua me te paru. Ehara i te mea ka taea e te kiriata hipoki te whakaiti i te urunga mai o te wai ua ki roto i te puranga paru, me te whakaiti i te nui o te wai rere e puta ana, engari ka ārai hoki i te horapa o ngā hau kakara e puta mai ana i te paru, me te whakapai ake i te kounga o te hau e karapoti ana.
1. Kōwhiringa kiriata hipoki: E ai ki te āhuatanga me ngā hiahia o te puranga paru, whiriwhiria te rauemi kiriata hipoki e tika ana. Ko te tikanga, me pai te mahi ārai-mimi, te mahi ārai-koroheketanga, te ātete ki te huarere me te kaha ki te kawe kawenga.
2. Ngā wāhi hanga: Me piri te whakatakotoranga o te kiriata hipoki ki te mata o te puranga paru kia kore ai e puta ngā āputa; ki ngā wāhi he nui ngā pari, me mahi ngā mahi whakapakari, pērā i te whakatakoto i ngā awaawa taunga me te whakatakoto i ngā paparanga taumaha, kia kore ai e paheke te kiriata hipoki. I taua wā anō, he mea nui anō te tuitui i waenga i ngā kiriata hipoki, ā, me whakamahi i tētahi tikanga hononga pono hei whakarite i te hiri.
Ngā Painga Taiao me ngā Pānga Hapori
Whai muri i te whakatakotoranga o te geomembrane ki roto i te puranga paru, me te whakatinana i te hanga membrane e hipoki ana i te wai ua me te paru, he mea whakamiharo ngā painga taiao. I tetahi taha, ka ārai pai i ngā ara parahanga o te wai rere o te puranga paru ki te wai whenua me te oneone, ā, ka tiaki i ngā rauemi wai whenua me te taiao oneone; I tetahi atu taha, mā te huri i te wai ua me te paru, ka whakaitihia te horo me te mimiti o te wai ua i roto i te puranga paru, ka whakaitihia te nui o te wai rere e puta ana, ā, ka whakaitihia te taumaha o te maimoatanga i muri mai. Hei tāpiri, mā te whakamahi i te kiriata hipoki ka whakapai ake i te tirohanga o te puranga paru me te kounga o te hau e karapoti ana, ā, ka whakapai ake i te kounga o te oranga o ngā kainoho.
I taua wā anō, kua whakatairangahia hoki e tēnei kaupapa te panonitanga, te whakapai ake me te whanaketanga matomato o te umanga tukatuka para. Nā te whakapai tonu o ngā ture me ngā whakaritenga taiao me te whakapai ake i te mōhiotanga o te marea ki te tiaki taiao, kua tīmata te maha o ngā wāhi tuku para ki te whakamahi i ngā hangarau ārai-mimi me ngā mahi whakatārewatanga wai ua me te paru kia tutuki ai he tikanga tuku para e pai ake ana ki te taiao, e whai hua ana, e pumau ana hoki. Ehara i te mea ka āwhina noa tēnei ki te whakaiti i te raruraru o te whakapae para o te tāone, engari ka tautoko hoki i te hanga i te ao taiao me te whakatutuki i te noho tahi pai i waenga i te tangata me te taiao.
I roto i te poto, ko te whakatakoto i ngā geo-membrane me te whakawhiti wai ua me te paru ki ngā papa paru he kaupapa tiaki taiao tino nui. Ehara i te mea ka taea anake te whakaoti i te raruraru parahanga taiao i roto i te tukanga tango para, engari ka whakatairanga hoki i te whakamahinga tika o ngā rauemi me te whanaketanga o te ōhanga porowhita. I te heke mai, me te whanaketanga tonu o te hangarau me te whakatairanga tonu i ngā tono, he take tā tātou ki te whakapono ka pai ake te taiao, ka whai hua, ka pumau hoki te tango para.
