Ngā kākahu whenua tiaki roritukanga whakatakoto
1. Te rokiroki, te kawe me te whakahaere i ngā geotextiles
Me tiaki ngā rōra geotextile mai i te kino i mua i te tāutanga. Me puranga ngā rōra geotextile ki tētahi wāhi kāore e pupū te wai, kaua te teitei o te puranga e neke ake i te whā ngā rōra, ā, kia kitea te wāhanga tautuhi o te rōra. Me hipoki ngā rōra geotextile ki ngā rauemi mātotoru hei ārai i te koroheketanga o te hihi UV. I te wā e rongoatia ana, me pupuri te pono o te tapanga me te pono o ngā raraunga.
Me tiaki ngā geotextiles mai i ngā kino i te wā e kawe ana, tae atu ki te kawe i te papa mahi mai i te rokiroki rauemi ki te wāhi mahi.
Me whakatika ngā kākahu whenua kua pakaru. Kāore e taea te whakamahi i ngā kākahu whenua kua tino tawhito. Kāore e whakaaetia kia whakamahia ngā kākahu whenua e pā ana ki ngā matū e turuturu ana i roto i tēnei kaupapa.
2. Te tikanga whakatakoto o te geotextile:
Pōkaihia ki te ringaringa; me papatahi te mata o te kakahu, ā, me waiho te āheinga whakarerekētanga kia rite ki te tika.
Ko te tāutanga o ngā kākahu miro, ngā kākahu poto rānei, ka mahia mā te hono i ngā hononga, te tuitui me te whakarewa. Ko te whānui o te tuitui me te whakarewa kei runga ake, ā, ko te whānui o te taupatupatu kei runga ake. Ko ngā kākahu ka roa pea te noho, me whakarewa, me tuitui rānei.
Te tuitui o te geotextile
Me mahi tonu te tuitui katoa (hei tauira, kāore e whakaaetia te tuitui). Me taupatupatu ngā kākahu whenua ki te 150 mm te iti rawa i mua i te taupatupatu. Ko te tawhiti tuitui iti rawa he 25 mm te iti rawa mai i te taha (te taha e kitea ana o te rauemi).
Ko ngā hononga o ngā geotextile kua tuitui paitia ko te tikanga tuitui mekameka kotahi-raina me te tikanga tuitui mekameka maukati-mekameka. Ko te miro e whakamahia ana mō te tuitui me waiho he rauemi kapia me te iti rawa o te kumenga neke atu i te 60 N me te ātete matū me te ātete UV rite, neke atu rānei i te ātete geotextile.
Me tuia anō te "ngira turuturu" ki te wāhi kua pāngia.
Me mahi ngā mahi e rite ana hei ārai i te oneone, i te matūriki, i te mea ke rānei kia kaua e uru ki roto i te geotextile i muri i te tāutanga.
Kakahu whenuaKa taea te wehewehe i ngā hononga piko ki ngā hononga piko tūturu, ngā tuitui, ngā whakapiringa rānei, i runga i te whenua me te mahi.
Te rerekētanga i waenga i te geotextile ārai-mimi me te geotextile mimi
Ina rere te wai mai i te paparanga oneone pai ki te paparanga oneone matotoru, ka werohia te muka polyester ki te geotextile he pai te uruhanga hau me te uruhanga wai kia whiti ai te wai, kia pai ai te kawe i ngā matūriki oneone, te onepu pai me ngā kohatu iti, kia mau tonu ai te paparanga oneone me te wai. Ka pumau te hangarau.
Ko te geotextile ārai-mimi tuatahi he momo rauemi matū polymer ngāwari, he iti te ōwehenga, he roa te roa, he kaha te hurihanga, he ātete ki te waikura, he iti te ātete ki te pāmahana me te ātete huka pai.
Ko te tikanga matua ko te tapahi i te awa turuturu o te tāke whenua-toka e te ātete o te kiriata kirihou. Ka whiwhi te kiriata kirihou i te pēhanga wai, ā, mā te pikinga o te kaha kume me te roa, ka taea te whakamahi hei whakarerekē i te āhua o te tāke; he pūhui hoki. Ko te matū muka poto, e whakatutuki ana i te kaha kume me te roa teitei ake mā te wero ngira, te hiri wera rānei, ehara i te mea ka whakanui noa i te ihirangi kirihou i muri i te whakakotahitanga.
Nā te mea he taratara te mata o te geotextile kore-whatu, ka whakanui ake te kaha kume me te ātete poka o te kiriata raraunga i te tauwehenga waku o te mata pā, he mea pai mō te pumau o te geomembrane hiato me te paparanga tiaki. Me te ātete tino pai ki te waikura huakita me te matū, kāore e wehi i te waikura waikawa, kawakore, tote.
Mahi: kaha pakaru teitei, tae atu ki te 20KN/m, ātete ki te ngokingoki me te waikura. Ka taea te whakamahi i roto i te tiaki wai, te tāhuna, te hanga huarahi tere, te taunga rererangi, te hanga, te tiaki taiao me ētahi atu kaupapa, ā, ka taea hoki te mahi hei tātari, hei rerenga wai, hei wehe, hei tiaki me te whakapakari.
