1. Menene ayyuka na nau'ikan geogrids daban-daban
A matsayin kayan da aka saba amfani da su wajen gina hanyoyi, geogrids suna taka muhimmiyar rawa wajen gina hanyoyin.A lokaci guda, geogrids kuma sun kasu kashi daban-daban.A yau za mu gabatar da rawar daban-daban na geogrids.
Akwai nau'ikan geogrids guda hudu.Bari mu gabatar da su:
1. Aikin Geogrid filastik Unidirectional:
Uniaxial tensile geogrid abu ne mai ƙarfi mai ƙarfi na geosynthetic.Ana amfani da shi sosai a cikin embankment, rami, wharf, babbar hanya, layin dogo, gini da sauran filayen.Babban amfaninsa shine kamar haka: ƙarfafa juzu'i, rarraba nauyin watsawa yadda ya kamata, inganta kwanciyar hankali da ƙarfin ɗaukar ƙasa, da tsawaita rayuwar sabis.Zai iya jure nauyi mai canzawa.Hana nakasar ƙasa da fashewar da ke haifar da asarar kayan ƙasa.Zai iya inganta ƙarfin ɗaukar kai na cikawa a bayan bangon riƙewa, rage matsa lamba na ƙasa na bangon riƙewa, adana farashi, tsawaita rayuwar sabis, da rage farashin kulawa.Haɗe tare da shotcrete da anka kankare hanya yi, gangara kiyayewa ba zai iya kawai ajiye 30% - 50% na zuba jari, amma kuma gajarta aikin da fiye da sau biyu.Ƙara geogrids zuwa matakin ƙasa da saman saman babbar hanya na iya rage jujjuyawar, rage ɓarna, jinkirta lokacin fashewa ta sau 3-9, kuma rage kauri na tsarin tsarin da kashi 36%.Yana da amfani ga kowane irin ƙasa, ba tare da buƙatar kayan aiki daga wasu wurare ba, kuma yana adana aiki da lokaci.Ginin yana da sauƙi da sauri, wanda zai iya rage yawan farashin ginin.Haɗin haɗin gwiwa na geogrid, tabbacin inganci.

2. Matsayin geogrid filastik ta hanyoyi biyu:
Haɓaka ƙarfin haɓakar tushe na hanya (ƙasa) kuma tsawaita rayuwar sabis na tushe (ƙasa).Hana rugujewa ko tsagewar saman hanya (ƙasa) kuma kiyaye ƙasa kyakkyawa da tsabta.Gine-gine masu dacewa, adana lokaci, ajiyar aiki, rage lokacin gini kuma rage farashin kulawa.Hana magudanar ruwa daga fashewa.Ƙarfafa gangaren ƙasa da hana asarar ruwa da ƙasa.Rage kauri na matashin kuma ajiye farashi.Goyon bayan bargawar yanayin korewar tabarmar dasa ciyawa a kan gangara.Yana iya maye gurbin ragar ƙarfe kuma a yi amfani da shi don rufin rufin ƙarya a ma'adinan kwal.
3. Matsayin karfe-roba geogrid:
Ana amfani da shi musamman a fagen ƙarfafa tushe mai laushi na ƙasa, riƙe bango da shingen juriya na injiniya na manyan tituna, titin dogo, ababen hawa, hanyoyin gabatowa, wharves, revetments, madatsun ruwa, yadudduka slag, da sauransu.
4. Aikin Gilashin fiber geogrid:
An ƙarfafa tsohon shingen kwalta don ƙarfafa saman kwalta da rigakafin cututtuka.Ana sake gina titin siminti zuwa wani tafki mai haɗaɗɗiya don hana faɗuwar tunani sakamakon raguwar faranti.Ana aikin fadada hanya da sake ginawa, tare da hana tsagewar da sababbi da tsohowar mahadar ta haifar da rashin daidaito.Maganin ƙarfafa tushen ƙasa mai laushi yana da kyau ga rabuwar ruwa da ƙarfafa ƙasa mai laushi, yadda ya kamata ya hana daidaitawa, rarraba damuwa na yau da kullum, da haɓaka ƙarfin gabaɗaya na ƙasa.Ƙarƙashin ƙaƙƙarfan tushe na sabon hanyar yana haifar da raguwa, kuma ana amfani da ƙarfafawa don hana tsagewar shingen da ke haifar da bayyanar fashewar tushe.

2. Yaya kyawun aikin hana gajiyar gajiya na geogrid
Geogrid yana amfani da fiber polyester mai ƙarfi ko fiber polypropylene azaman albarkatun ƙasa, yana ɗaukar tsarin saƙa warp, kuma yadudduka da yadudduka a cikin masana'anta ba su da lanƙwasa, kuma an ɗaure mahadar kuma an haɗa shi tare da filament mai ƙarfi mai ƙarfi don samar da m batu batu, ba da cikakken wasa zuwa ta inji Properties.Don haka ko kun san yadda juriya ga gajiyawarsa ke da kyau?
Babban tasirin kwalta mai rufi a kan tsohon shingen siminti shi ne don inganta aikin aikace-aikacen shimfidar, amma ba shi da gudummawa kaɗan ga tasirin.Tsayayyen shimfidar shimfidar wuri a ƙarƙashin rufin har yanzu yana da tasiri mai mahimmanci.Rufaffen kwalta da ke kan tsohon ginin kwalta na kankare ya bambanta.Rufin kwalta zai ɗauki kaya tare da tsohon kwalta siminti.Don haka, rufin kwalta a kan shingen kankare na kwalta ba wai kawai zai nuna tsagewar tunani ba, har ma yana nuna fashewar gajiya saboda tasirin lodin na dogon lokaci.Bari mu yi nazarin yanayin lodin kwalta mai rufi a kan tsohon kwalta na kankare: saboda kwalta mai rufi abu ne mai sassauƙa mai sassauƙa mai sassauƙa da kadara iri ɗaya da abin rufewar kwalta, lokacin da aka yi tasirin lodin, shimfidar za ta sami karkata.Rufin kwalta wanda ke taɓa dabaran kai tsaye yana ƙarƙashin matsin lamba, kuma saman yana ƙarƙashin ƙarfin juzu'i a cikin yankin da ke wajen gefen abin hawan keken.Saboda abubuwan da ke da karfi na bangarorin biyu na damuwa sun bambanta kuma suna kusa da juna, yana da sauƙi a lalace a mahadar wuraren damuwa guda biyu, wato canjin karfi na kwatsam.A ƙarƙashin tasirin nauyin dogon lokaci, gajiyawar gajiya yana faruwa.
Geogrid na iya tarwatsa matsananciyar matsananciyar damuwa na sama da damuwa mai ƙarfi a cikin rufin kwalta don samar da yankin buffer tsakanin wuraren damuwa guda biyu, inda damuwa ke canzawa a hankali maimakon ba zato ba tsammani, yana rage lalacewar damuwa kwatsam zuwa canjin kwalta.Ƙananan elongation na gilashin fiber geogrid yana rage karkatar da shimfidar wuri kuma yana tabbatar da cewa shimfidar ba zai sami nakasar canji ba.
Geogrid Unidirectional ana fitar da shi zuwa cikin sirararen zanen gado ta hanyar polymer (polypropylene PP ko polyethylene HDPE), sannan a huda shi cikin hanyar sadarwar ramin na yau da kullun, sannan kuma a shimfiɗa shi a tsaye.A cikin wannan tsari, polymer yana cikin yanayin layi, yana samar da tsarin hanyar sadarwa mai tsayi mai tsayi tare da rarraba iri ɗaya da ƙarfin kumburi.
Unidirectional Grid wani nau'i ne na kayan geosynthetic mai ƙarfi, wanda za'a iya raba shi zuwa grid polypropylene unidirectional da grid polyethylene unidirectional.
Uniaxial tensile geogrid wani nau'i ne na geotextile mai ƙarfi mai ƙarfi tare da babban polymer kwayoyin halitta azaman babban albarkatun ƙasa, wanda aka ƙara tare da wasu magungunan anti ultraviolet da anti-tsufa.Bayan tashin hankali na uniaxial, asalin ƙwayoyin sarkar da aka rarraba suna komawa zuwa yanayin layi, sannan a fitar da su cikin faranti na bakin ciki, suna yin tasiri ga raga na al'ada, sannan a shimfiɗa su a tsaye.Kimiyyar Material.
A cikin wannan tsari, ana jagorantar polymer ta hanyar layin layi, yana samar da tsarin cibiyar sadarwa mai tsayi mai tsayi tare da rarraba iri ɗaya da ƙarfin kumburi.Wannan tsarin yana da ƙarfin ƙarfi mai ƙarfi sosai da ƙarancin ƙarfi.Ƙarfin ƙarfi shine 100-200Mpa, wanda ke kusa da matakin ƙananan ƙarfe na carbon, kuma ya fi kyau fiye da kayan ƙarfafa na gargajiya ko na yanzu.
Musamman, wannan samfurin yana da matsananci-high farkon matakin kasa da kasa (tsawaitawa na 2% - 5%) ƙarfin juyi da modules.Yana ba da kyakkyawan tsari don ƙaddamar da ƙasa da yaduwa.Wannan samfurin yana da ƙarfi mai ƙarfi (> 150Mpa) kuma ya dace da kowane irin ƙasa.Abu ne mai ƙarfi da ake amfani da shi sosai a halin yanzu.Babban halayensa shine ƙarfin ƙarfi mai ƙarfi, kyakkyawan aiki mai raɗaɗi, ingantaccen gini da ƙarancin farashi.
