1 、 Ni ubuhe butumwa bw'ubwoko butandukanye bwa geogridi
Nibikoresho bisanzwe bikoreshwa mukubaka umuhanda, geogrid igira uruhare runini mukubaka umuhanda.Mugihe kimwe, geogrid nayo igabanijwe muburyo butandukanye.Uyu munsi tuzamenyekanisha uruhare rwubwoko butandukanye bwa geogrid.
Hariho ubwoko bune bwa geogrid.Reka tubamenyeshe:
1. Imikorere ya plastike geogrid idafite icyerekezo:
Uniaxial tensile geogrid nikintu gikomeye-geosintetike.Ikoreshwa cyane mu nkombe, mu mwobo, ku kayira, umuhanda, gari ya moshi, ubwubatsi n'indi mirima.Imikoreshereze yacyo nyamukuru niyi ikurikira: gushimangira subgrade, gukwirakwiza neza umutwaro wo gukwirakwiza, kunoza ituze no gutwara ubushobozi bwa subgrade, no kongera ubuzima bwa serivisi.Irashobora kwihanganira umutwaro munini usimburana.Irinde kugabanuka kwa subgrade no guturika biterwa no gutakaza ibikoresho bya subgrade.Irashobora kunoza ubushobozi bwo kwikorera kwuzuza inyuma yurukuta rugumaho, kugabanya umuvuduko wisi wurukuta rugumana, kuzigama ibiciro, kongera igihe cya serivisi, no kugabanya amafaranga yo kubungabunga.Ufatanije nuburyo bwo kubaka beto na beto, gufata neza ntibishobora kuzigama 30% - 50% yishoramari gusa, ariko kandi bigabanya igihe cyubwubatsi inshuro zirenze ebyiri.Ongeramo geogride kuri subgrade no hejuru yubuso bwumuhanda birashobora kugabanya gutandukana, kugabanya gutembera, gutinza igihe cyo guturika inshuro 3-9, kandi bikagabanya umubyimba wububiko bwa 36%.Irakoreshwa mubutaka bwose, bidakenewe ibikoresho biva ahandi, kandi bizigama umurimo nigihe.Ubwubatsi buroroshye kandi bwihuse, bushobora kugabanya cyane ibiciro byubwubatsi.Kwagura hamwe kwa geogrid, ubwishingizi bufite ireme.

2. Uruhare rwa geogrid ya plastike ebyiri:
Ongera ubushobozi bwo kwishyiriraho umuhanda (hasi) kandi wongere igihe cyo gukora cyumuhanda (hasi).Irinde gusenyuka cyangwa guturika hejuru yumuhanda (hasi) kandi ugumane ubutaka bwiza kandi butunganijwe.Kubaka neza, kuzigama igihe, kuzigama umurimo, kugabanya igihe cyubwubatsi no kugabanya amafaranga yo kubungabunga.Irinde umuyonga guturika.Komeza ubutumburuke bwubutaka no kwirinda amazi nubutaka.Mugabanye ubunini bwigitambara kandi uzigame ikiguzi.Shigikira icyatsi kibisi kibisi cyo gutera ibyatsi kumurongo.Irashobora gusimbuza icyuma kandi igakoreshwa mugisenge cyibinyoma mumabuye yamakara.
3. Uruhare rwa geogrid:
Ikoreshwa cyane cyane mumirima yubutaka bworoshye bwo gushimangira ubutaka, kugumana urukuta na pavement yamashanyarazi yubukorikori bwimihanda minini, gari ya moshi, abut, inzira, inzira, ibyerekezo, ingomero, imbuga za slag, nibindi.
4. Imikorere ya fibre fibre geogrid:
Umuhanda wa asfalt ushaje ushimangirwa kugirango ushimangire hejuru ya asfalt no kwirinda indwara.Umuhanda wa sima wa sima wongeye kubakwa muburyo bwa kaburimbo kugirango wirinde gucikamo ibice biterwa no kugabanuka kw'isahani.Kwagura umuhanda no kwiyubaka, birinda gucikamo ibice biterwa nisangano rishaje kandi rishaje hamwe no gutura neza.Gutunganya imbaraga zubutaka bworoshye bifasha gutandukanya amazi no guhuza ubutaka bworoshye, bikabuza neza gutura, kugabana imihangayiko imwe, no kongera imbaraga muri rusange.Igice cya kabiri gikomeye cyumuhanda mushya gitanga ibice byo kugabanuka, kandi gushimangira bikoreshwa mukurinda ibice bya kaburimbo biterwa no kwerekana ibice byashingiweho.

2 、 Nibyiza ko anti-fatigue yameneka ya geogrid
Geogrid ikoresha fibre fibre ikomeye cyane cyangwa fibre polypropilene nkibikoresho fatizo, ifata icyerekezo cyerekezo cyo kuboha, kandi imyenda yintambara nu mwenda mubudodo ntigishobora kunama, kandi ihuriro rihambiriwe kandi rihujwe hamwe na fibre fibre ikomeye cyane kugirango ikore a ingingo ihuza ingingo, itanga umukino wuzuye kumiterere yubukanishi.Noneho 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 ntigira uruhare runini mubikorwa byo kubyara.Umuhanda wa kaburimbo ukomye munsi yikigina uracyafite ingaruka zikomeye.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 asifalt ntizerekana gusa ibice byerekana, ahubwo izerekana umunaniro kubera umunaniro muremure wumutwaro.Reka dusesengure imizigo yuburyo bwa asfalt hejuru ya kaburimbo ishaje ya asfalt: kubera ko asifalt yuzuye ni igorofa yoroheje igaragara hamwe numutungo umwe na asifalt, iyo ikorewe ingaruka zumutwaro, pavement izaba ifite deflection.Igice cya asfalt gikora ku ruziga kiri munsi yigitutu, kandi hejuru hashobora gukoreshwa imbaraga zingana mukarere kari hanze yimodoka.Kuberako imbaraga zingirakamaro mubice byombi bitesha umutwe ziratandukanye kandi zegeranye, biroroshye kwangirika aho ihuriro ryibice byombi bihangayikishije, aribyo guhindura imbaraga zitunguranye.Ingaruka yumutwaro muremure, gucika umunaniro bibaho.
Geogrid irashobora gukwirakwiza impungenge zo hejuru hamwe no guhangayikishwa cyane na asfalt kugirango habeho akarere ka buffer hagati y’ibice byombi bihangayikishije, aho imihangayiko ihinduka gahoro gahoro aho gutungurana, bikagabanya ibyangiritse byimpinduka ihinduka ritunguranye kuri asfalt.Uburebure buke bwa fibre fibre geogrid igabanya gutandukana kwa kaburimbo kandi ikemeza ko kaburimbo itazagira ihinduka ryinzibacyuho.
Geogrid idafite icyerekezo isohorwa mumabati yoroheje na polymer (polypropilene PP cyangwa polyethylene HDPE), hanyuma igakubitwa mumiyoboro isanzwe, hanyuma ikaramburwa igihe kirekire.Muri ubu buryo, polymer iri mumurongo umwe, ikora urwego rurerure rwimikorere ya elliptique hamwe nogukwirakwiza kimwe hamwe nimbaraga nini.
Imiyoboro idahwitse ni ubwoko bwibikoresho byinshi bya geosintetike, bishobora 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 guhagarika umutima, molekile yumwimerere yagabanijwe ihindurwamo umurongo umwe, hanyuma ikoherezwa mu isahani yoroheje, ikagira ingaruka kuri meshi isanzwe, hanyuma ikaramburwa igihe kirekire.Ubumenyi bwibikoresho.
Muri ubu buryo, polymer iyobowe numurongo ugaragara, ikora urwego rurerure rwa elliptique imiterere hamwe nogukwirakwiza hamwe nimbaraga ndende.Iyi miterere ifite imbaraga zingana cyane na modulus ya tensile.Imbaraga zingana ni 100-200Mpa, yegereye urwego rwibyuma bya karubone nkeya, kandi nibyiza cyane kuruta ibikoresho gakondo cyangwa bihari.
By'umwihariko, iki gicuruzwa gifite ultra-high kare 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 kibereye ubwoko bwose bwubutaka.Nibikoresho bikoreshwa cyane gushimangira ubungubu.Ibiranga nyamukuru ni imbaraga zingana cyane, gukora neza neza, kubaka byoroshye nigiciro gito.
