Hanganga taketake
Ko te geomembrane maeneene he mea hanga i te nuinga o te wā ki te rauemi polymer kotahi, pērā i te polyethylene (PE), te polyvinyl chloride (PVC), me ētahi atu. He maeneene, he papatahi tōna mata, kāore he kakano, he matūriki rānei e kitea ana.
- Ngā Āhuatanga
- He pai te mahi ārai-mimi: He tino iti te uruhanga, ā, ka taea te ārai i te urunga o ngā wai. He pai te pānga ārai ki te wai, te hinu, ngā otinga matū, me ētahi atu. Ka taea e te tauwehenga ārai-mimi te eke ki te 1×10⁻¹²cm/s ki te 1×10⁻¹⁷cm/s, ka taea te whakatutuki i ngā whakaritenga ārai-mimi o te nuinga o ngā kaupapa.
- Pūmautanga matū kaha: He tino pai te ātete ki te waikawa me te kawakore me te ātete ki te waikura. Ka taea te noho pumau i roto i ngā taiao matū rerekē, ā, kāore e ngawari te memeha e ngā matū o te oneone. Ka taea e ia te ātete ki te waikura o ētahi kukū o te waikawa, te kawakore, te tote me ētahi atu otinga.
- He ātete pai ki te pāmahana iti: Ka taea tonu te pupuri i te ngāwari me ngā āhuatanga miihini pai i roto i te taiao pāmahana iti. Hei tauira, ko ētahi geomembranes maeneene polyethylene kounga teitei he ngāwari tonu i te -60℃ ki te -70℃, ā, kāore e ngawari ki te pakaru.
- Hanganga watea: He maeneene te mata, he iti te tauwehenga waku, he watea mō te whakatakoto ki runga i ngā whenua me ngā turanga rerekē. Ka taea te hono mā te whakarewa, te here me ētahi atu tikanga. He tere te tere o te hanga, ā, he ngāwari te whakahaere i te kounga.
Tukanga Whakaputa
- Tikanga pupuhi whakaputa: Ka whakamahanahia te rauemi mata polymer ki te āhua rewa, ka whakaputa mā te extruder hei hanga i te puka ngongo. Kātahi ka pupuhihia te hau kōpeke ki roto i te puka ngongo kia whānui ai, kia piri ai ki te puka hei whakamatao me te hanga. Hei whakamutunga, ka whiwhihia he geomembrane maeneene mā te tapahi. He matotoru ōrite te geomembrane i hangaia mā tēnei tikanga, ā, he pai ngā āhuatanga miihini.
- Tikanga whakatakoto maramataka: Ka whakamahanahia te rauemi mata o te polymer, kātahi ka whakaputahia, ka totorohia mā roto i ngā roera maha o te maramataka hei hanga i tētahi kiriata he matotoru, he whānui hoki. I muri i te whakamatao, ka puta he geomembrane maeneene. He tino pai te whakaputa o tēnei tukanga, he whānui hoki te hua, engari he ngoikore te ōrite o te matotoru.
Ngā Āpure Tono
- Kaupapa tiaki wai: E whakamahia ana mō te maimoatanga ārai-mimi o ngā whare tiaki wai pēnei i ngā puna wai, ngā tāhuna, me ngā awaawa. Ka taea e ia te ārai i te turuturu wai, te whakapai ake i te penapena wai me te whai huatanga o te kawe wai o ngā kaupapa tiaki wai, me te whakaroa i te roa o te mahi o te kaupapa.
- Papa Para: Hei ārai i te turuturu i te raro me te taha o te papa para, ka ārai i te wai rere kei poke i te oneone me te wai whenua, ā, ka tiaki hoki i te taiao taiao e karapoti ana.
- Ārai wai o te whare: Ka whakamahia hei paparanga ā-wai i te tuanui, i te rūma o raro, i te kaukau me ētahi atu wāhanga o te whare hei ārai i te urunga o te wai ua, te wai whenua me ētahi atu makuku ki roto i te whare, me te whakapai ake i te mahi ā-wai o te whare.
- Whenua horihori: Ka whakamahia hei ārai i te turuturu o ngā roto horihori, ngā puna kaukau, ngā papa korowha, me ētahi atu, hei pupuri i te pumau o te wai, hei whakaiti i te turuturu o te wai, hei whakarato hoki i te turanga pai mō te waihanga whenua.
Ngā Whakatakotoranga me ngā Tohu Hangarau
- Ngā Whakatakotoranga: Ko te matotoru o te geomembrane maeneene kei waenganui i te 0.2mm me te 3.0mm, ā, ko te whānui kei waenganui i te 1m me te 8m, ka taea te whakarite kia rite ki ngā hiahia o ngā kaupapa rerekē.
- Ngā tohu hangarau: Kei roto ko te kaha kume, te roa i te whati, te kaha haehae koki-matau, te ātete pēhanga waipū, me ētahi atu. Ko te kaha kume kei waenganui i te 5MPa me te 30MPa, ko te roa i te whati kei waenganui i te 300% me te 1000%, ko te kaha haehae koki-matau kei waenganui i te 50N/mm me te 300N/mm, ā, ko te ātete pēhanga waipū kei waenganui i te 0.5MPa me te 3.0MPa.
