Geogrid ikoresha fibre fibre-fibre fibre cyangwa polypropilene fibre nkibikoresho fatizo, kandi ikoresha imiterere yububiko.Imyenda yintambara nu mwenda mubudodo ntizishobora kunama, kandi ihuriro rihambiriwe hamwe na fibre fibre ikomeye cyane kugirango ihuze urugingo rukomeye, itanga umukino wuzuye muburyo bwa mashini.Waba uzi ukuntu kurwanya umunaniro wacyo ari byiza?
Ingaruka nyamukuru ya asfalt yuzuye hejuru ya sima ya beto ishaje ni ukunoza imikorere yimikorere ya kaburimbo, ariko ntabwo itanga umusanzu munini mubikorwa.Umuhanda wa beto uhamye munsi yumurongo uracyafite uruhare runini mukubyara.Asfalt yuzuye hejuru ya asfalt ishaje ya kaburimbo iratandukanye.Igice cya asfalt kizaremerera umutwaro hamwe na kaburimbo ishaje ya asfalt.Kubwibyo, asfalt yuzuye hejuru ya kaburimbo ya asfalt ntabwo izerekana gusa ibice byerekana, ahubwo izanagabanya umunaniro bitewe ningaruka ndende yumutwaro.Reka dusesengure impungenge ziterwa na asfalt hejuru ya kaburimbo ishaje ya asfalt: kubera ko hejuru ya asfalt ni pavement yoroheje ifite kamere imwe na asfalt yuzuye, ubuso bwumuhanda buzahinduka iyo bikorewe ingaruka zumutwaro.Igice cya asfalt gikora ku ruziga kiri munsi yigitutu, kandi hejuru irashobora guhangayikishwa mukarere karenze umutwaro wikiziga.Kuberako imbaraga zimiterere yibice byombi bitesha umutwe kandi zegeranye hagati yazo, ihuriro ryibice byombi bihangayikishije, ni ukuvuga guhindura imbaraga zitunguranye, byoroshye kwangirika.Ingaruka yumutwaro muremure, gucika umunaniro bibaho.
Muri asfalt yuzuye, geotextile irashobora kugabanya imihangayiko yo hejuru yo guhagarika umutima hamwe no guhagarika umutima, kandi igakora zone tampon hagati yibice byombi bitesha umutwe.Hano, imihangayiko ihinduka buhoro buhoro aho gutungurana, kugabanya ibyangiritse hejuru ya asfalt iterwa nimpinduka zitunguranye.Uburebure buke bwa fibre fibre geogrid igabanya gutandukana kwa kaburimbo kandi ikemeza ko kaburimbo itazagira ikibazo cyo guhindura ibintu.
Geogrid idafite icyerekezo isohorwa mumabati yoroheje na polymer (polypropilene PP cyangwa polyethylene HDPE), hanyuma igakubitwa inshundura zisanzwe, hanyuma ikaramburwa igihe kirekire.Muri ubu buryo, polymer iri mumurongo ugizwe, ikora urwego rurerure rwa oval hamwe nogukwirakwiza kimwe hamwe nimbaraga nini.
Imiyoboro idafite icyerekezo ni ubwoko bwa geosynthetike-ikomeye cyane, ishobora kugabanywamo gride ya polypropilene idafite icyerekezo hamwe na gride polyethylene.
Uniaxial tensile geogrid ni ubwoko bwa geotextile ifite imbaraga nyinshi hamwe na polymer nyinshi cyane nkibikoresho nyamukuru, byongeweho hamwe na anti-ultraviolet hamwe na anti-gusaza.Nyuma yo kurambura icyerekezo kimwe, umwimerere wagabanijwe urunigi rwerekejwe kumurongo umwe, hanyuma ujyanwa mu isahani yoroheje, bigira ingaruka kuri meshi isanzwe, hanyuma urambura uburebure.Ubumenyi bwibikoresho.
Muri ubu buryo, polymer iyobowe numurongo ugaragara, ikora urwego rurerure rwa elliptique imiterere hamwe no gukwirakwiza hamwe nimbaraga nini.Iyi miterere ifite imbaraga zingana cyane na modulus ya tensile.Imbaraga zingana ni 100-200Mpa, hafi yurwego rwibyuma bya karubone nkeya, bikaba byiza cyane kuruta ibikoresho gakondo cyangwa bihari.
By'umwihariko, iki gicuruzwa gifite ultra-high yo hambere kurwego mpuzamahanga (kurambura 2% - 5%) imbaraga zingana na modulus ya tensile.Itanga uburyo bwiza bwo kwiyemeza ubutaka no gukwirakwiza.Iki gicuruzwa gifite imbaraga zingana (> 150Mpa) kandi kirakoreshwa mubutaka butandukanye.Nubwoko bwibikoresho bishimangira bikoreshwa muri iki gihe.Ibiranga nyamukuru ni imbaraga zingana cyane, gukora neza neza, kubaka byoroshye nigiciro gito.
