Ka whakamahia e Geogrid te muka polyester kaha teitei, te muka polypropylene ranei hei rauemi mata, me te whakamahi i te hanga hangai hangai i te whenu knitting.Ko nga whenu me nga weft i roto i te papanga he kore e piko, a ka herea te whakawhitinga ki te kakawaea muka kaha-kaha hei hanga i tetahi hononga u, e hoatu ana i te takaro katoa ki ona ahuatanga miihini.Kei te mohio koe he pehea te pai o tana atete kapiti ngenge?
Ko te painga nui o te whakakikorua o te uku ki runga i te papa raima sima tawhito ko te whakapai ake i te mahi tono o te papaahi, engari kaore e nui te whai waahi ki te whai hua.Ko te papa raima i raro i te whakakikorua ka whai waahi nui tonu ki te kawe.He rerekee te whakakikorua o te uku i runga i te papa raima raima tawhito.Ko te whakakikorua uku ka mau i te kawenga me te papa raima raima tawhito.No reira, ko te whakakikorua o te uku ki runga i te papa raima raima ka kore noa e puta nga kapiti whakaata, engari ka pakaru ano hoki te ngenge i runga i te paanga roa o te utaina.Ka wetewetehia te ahotea o te whakakikorua o te parapara i runga i te papa raima parapara tawhito: na te mea ko te whakakikorua o te parapara he papa ngawari he rite tonu te ahua ki te whakakikorua o te parapara, ka paopao te mata o te huarahi ina pa ana ki te taumahatanga.Ko te whakakikorua o te uku e pa tika ana ki te wira kei raro i te pehanga, a ko te mata kei raro i te awangawanga i te waahi kei tua atu i te tawhē utaina wira.Na te mea he rereke nga ahuatanga kaha o nga waahi ahotea e rua me te tata ki a ratau, ko te hononga o nga waahi ahotea e rua, ara, ko te huringa ohorere o te kaha, he ngawari ki te pakaru.I raro i te paanga o te kawenga mo te wa roa, ka pakaru te ngenge.
I roto i te whakakikorua o te uku, ka taea e te geotextile te wetewete i te ahotea o runga ake nei me te ahotea, ka hanga he rohe parepare i waenga i nga waahanga e rua e mau ana.I konei, ka huri haere te ahotea, kaua e ohorere, ka whakaiti i te kino o te whakakikorua o te uku na te huringa ohorere.Ko te iti o te roanga o te muka karaihe geogrid ka whakaiti i te paheketanga o te papaahi me te whakarite kia kore te papaahi e pa ki te huringa whakawhiti.
Ka werohia te papahanga whenua kotahi ki roto i nga pepa angiangi e te polymer (polypropylene PP, polyethylene HDPE ranei), ka werohia ki roto i te mata, ka totoro roa.I roto i tenei tukanga, ko te polymer i roto i te ahua raina, ka hanga i te hanganga whatunga porotītaha roa me te tohatoha rite me te kaha o te node teitei.
Ko te mahinga kotahi he ahua o te geosynthetics kaha-nui, ka taea te wehewehe ki te mahinga polypropylene unidirectional me te polyethylene grid unidirectional.
Ko te uniaxial tensile geogrid he ahua o te geotextile kaha-nui me te polymer ngota teitei hei rauemi mata matua, ka taapirihia me etahi anti ultraviolet me nga kaihoko anti-pakeke.Whai muri i te toronga kotahi, ka hurihia nga ngota ngota mekameka kua tohatoha ki te ahua raina, katahi ka tukuna ki roto i te pereti angiangi, ka pa ki te mata o te tikanga, ka totoro roa.Pūtaiao Rawa.
I roto i tenei tukanga, ka arahina te polymer e te ahua o te raina, ka hangaia he hanganga whatunga elliptical roa me te tohatoha rite me te kaha o te node teitei.Ko tenei hanganga he tino kaha te kaha me te whakakorikori.Ko te kaha tensile he 100-200Mpa, tata ki te taumata o te waro waro iti, he pai ake i nga taonga tuku iho, o naianei ranei.
Ina koa, ko tenei hua he taumata teitei moata o te ao (te roanga o te 2% - 5%) te kaha o te kaha me te whakanekeneke.Ka whakaratohia he punaha pai mo te pumau me te tohatoha o te oneone.He nui te kaha o tenei hua (> 150Mpa) a e pa ana ki nga momo oneone.He momo rauemi whakakaha e whakamahia nuitia ana i naianei.Ko ona ahuatanga matua ko te kaha kaha, te mahi ngokingoki pai, te hanga watea me te utu iti.
