Te āhuatanga taketake o te geogrid whana polypropylene e toru-ara me te totoro

1. Te āhuatanga taketake o te geogrid whana polypropylene e toru-ara me te totoro

（1) Te whakamāramatanga me te tukanga whakaputa

Ko te geogrid kume polypropylene toru-ara he momo rauemi whakapakari whenua hou i whakawhanakehia, i whakapaitia hoki i runga i te kaupapa o te geogrid kume uniaxial me te geogrid kume biaxial. Ko te tukanga whakaputa ko te polypropylene te rauemi matua, mā te extrusion, te hanga pereti me te kume, kātahi ka totoro roa me te whakawhiti, me te totoro aronga z, e hangaia ana mā te tāpiri i te totoro kotahi ahunga ki te ahunga toru-ahu.

（2) Ngā āhuatanga hanganga

1. Hanganga tapatoru ahurei

• He pumau tēnei hanganga, he pai ake te pumau i ngā whatunga kotahi-angihanga me ngā whatunga rua-angihanga, ā, ka taea te pikau i ngā kawenga maha-angihanga i te wā kotahi, kia pai ake ai te hora i ngā kawenga.

• Ngā āhuatanga kume i ngā ahunga toru-ahu

• He kaha tōna pānga kume i te ahunga toru-ahu, ā, ka tino kitea te pānga o te aukati me te whakahaere i te horo oneone i ngā ahunga rerekē. He kaha kume nui, ehara i te mea i ngā ahunga roa me ngā ahunga whakawhiti anake, engari ka taea hoki te whakanui ake i te waku ina pa katoa ki te papa whenua, ā, ka ārai i te horo oneone o te papa whenua.

2. Ngā painga mahi o te werohanga polypropylene-ara-toru me te geogrid tensile

（1) Ngā āhuatanga miihini

1. Te kaha kume teitei

• He kaha nui te kume o te hua tonu, ka taea te urutau ki ngā whakaritenga ahotea i roto i ngā momo taiao hangarau, ā, ka taea te whakamahi hei whakapakari i ngā wāhanga hangarau e hiahia ana ki te pikau i ngā kaha kume nui, pērā i ngā momo tāke me ngā papa raro.

• Te pumau teitei

• Nā tōna hanganga ahurei e toru-ara, ka taea e ia te whakarato i tētahi pūnaha honohono pai rawa atu mō te kawe kaha me te horapa ki roto i te oneone, ka taea te urutau ki te whakapakari i te turanga tautoko pumau o te rohe whānui, me te whakarei ake i te pumau o te turanga. Hei tauira, he mahi nui tāna i roto i te whakapakari i te papa o raro o te huarahi me te rerewē me te hangarau pakitara pupuri whakapakari 34.

（2) Te pakari

1. Te roa o te ora ratonga

• He tino pakari te rauemi, kāore e ngāwari ki te pakaru i te wā e whakamahia ana mō te wā roa, ka taea te whakaiti i ngā utu tiaki i te wā e whakamahia ana, ā, he pai mō ngā kaupapa he nui te roa o te mau, pērā i ngā taunga rererangi nunui, ngā papa waka, me ētahi atu.

• He ātete pai ake ki te waikura

• He kaha ātete-waikura anō tō te rauemi polypropylene, ka taea te pupuri i te mahi pumau i raro i ngā āhuatanga oneone me te taiao rerekē, me te whakaiti i te tūponotanga o te hekenga o te mahi a te rauemi i puta mai i te waikura.

（3) Ētahi atu painga

1. Mama

• He māmā ake, ka taea te whakakapi i te mata whakarewa taumaha, he watea mō te kawe me te tāuta i roto i te tukanga hanga, ka taea te whakapai ake i te whai huatanga o te hanga, te whakaiti i te uauatanga me te utu o te hanga, hei tauira, ina taea te whakamahi hei tautoko tiaki, hei tuanui rūpahu, me ētahi atu. I roto i te keri whenua i roto i ngā maina waro, he watea te taumaha mama mō te whakahaere.

• Te mahi utu nui

• He iti te utu, he nui hoki te mahi a tēnei i roto i ngā hua geosynthetic maha. Ka taea e ia te whakahaere pai i ngā utu hangarau me te whakatutuki i ngā hiahia hangarau. Nō reira, he tino rongonui ki te marea, ā, he whānuitia ngā tono, tae atu ki ngā momo tāhuna, ngā papa whenua, me ngā pari. Te tiaki, ngā taunga rererangi, ngā papa waka me ētahi atu kaupapa.
