2025-02-13

1. Inkcazelo yefayibha yebasalt i-geogrid
I-Basalt geogrid I-basalt fiber thread ikhethwa, ukusetyenziswa komatshini wokuluka we-warp ophucukileyo wangaphandle othungwe kwi-substrate, ukusetyenziswa kwesakhiwo sokuluka se-warp, ukusebenzisa ngokupheleleyo ilaphu elikwimeko yamandla e-thread, ukuphucula iimpawu zalo zoomatshini, ukuze libe namandla okutyhafa, amandla okukrazula kunye nokumelana nokuqhekeka, kwaye emva kwe-asphalt eguqulweyo esemgangathweni ophezulu egqunywe ngenethiwekhi yeplanar yezinto. Ilandela umgaqo wokuhambelana okufanayo, igxile ekusebenzeni kwayo okudibeneyo kunye nomxube we-asphalt, kwaye ikhusele ngokupheleleyo i-substrate ye-fiber, iphucula kakhulu ukumelana nokukrweleka kunye nokumelana nokucheba kwe-substrate, ukuze isetyenziselwe ukuphucula indlela yokuhamba, ukumelana nokuqhekeka kweendlela kunye nezinye iingozi zendlela, kwaye ukuphelisa indlela yokuhamba kwe-asphalt kunzima ukuphucula ingxaki.

2. Iimpawu ze-fibre geogrid esisiseko

Le mveliso ineenzuzo zokuba Amandla aphezulu, ukunwebeka okuphantsi, ukumelana nobushushu obuphezulu, imodulus ephezulu, ubunzima obulula, ukuqina okuhle, ukumelana nokugqwala, ubomi benkonzo ende, kulula ukuyilingana, njl.njl., ingasetyenziswa kakhulu kwindlela endala yesamente, ukugcinwa kwendlela yeenqwelo moya, udonga lomlambo, ukhuseleko lwethambeka, unyango lokuphucula indlela yendlela kunye nebhulorho kunye nezinye iindawo zobunjineli, ingenza indlela yokwandisa ukuqina, ukuqinisa, ukuthintela ukudinwa kwemigudu kwiindlela, ukwandiswa kobushushu nokubanda kunye nokuqhekeka okubonakalayo okulandelayo, kwaye Ingasasaza uxinzelelo lokuthwala indlela kwaye yandise ubomi benkonzo yendlela.
Amandla aphezulu okutsalwa kunye nobude obuphantsi: i-basalt fiber geogrid isekelwe kwi-basalt fiber njengezinto eziluhlaza, kwaye amandla okutsalwa kwe-basalt fiber aphezulu kakhulu, ngaphezu kwezinye iifayibha kunye nesinyithi esiqhelekileyo. Kwangaxeshanye ine-modulus ephezulu, inokumelana okuphezulu nokuguquguquka, ubude bokwaphuka bungaphantsi kwe-3%.
Akukho kuqhekeka kwexesha elide: njengesixhobo sokuqinisa, esinokukwazi ukumelana nokuguquguquka kwimeko yomthwalo wexesha elide, ukumelana nokuqhekeka kubaluleke kakhulu, i-basalt fiber ayizukuqhekeka, ukuqinisekisa ukuba imveliso inokugcina ukusebenza ixesha elide.
Uzinzo olugqwesileyo lomzimba nolweekhemikhali: ifayibha yebasalt ngokwayo inokumelana kakhulu nokugqwala kweasidi kunye ne-alkali, i-basalt geogrid inokumelana nokwaphuka okwahlukeneyo komzimba kunye nokugqwala kweekhemikhali, kodwa ikwachasene nokugqwala kwezinto eziphilayo kunye notshintsho lwemozulu, ukuqinisekisa ukuba ukusebenza kwayo akulahleki.
Uzinzo oluhle lobushushu: iqondo lokunyibilika kwefayibha ye-basalt kwi-1500 ° C nangaphezulu, ukusetyenziswa kwexesha elide kobushushu phakathi kwe--260 ° ~ 650 °, ukuqinisekisa ukuba i-basalt geogrid ekusebenzeni kwepaving ukuze kumelwane nokuzinza kobushushu obuphezulu.
Ingqokelela yesitshixo esifakwe ngaphakathi kunye nesithintelo: kuba i-basalt geogrid yisakhiwo se-mesh, ikhonkrithi ye-asphalt kwi-aggregate inokungenwa, ukuze ukwakheka kwesitshixo esifakwe ngoomatshini. Olu thintelo luthintela ukuhamba kwee-aggregates, ukuze umxube we-asphalt kwimeko yomthwalo ufikelele kwimeko engcono yokuxinana, amandla aphezulu okuthwala umthwalo, ukusebenza ngcono kokudluliselwa komthwalo kunye nokuguquguquka okuncinci.
Kwaye ukuhambelana komxube we-asphalt: i-basalt geogrid kwinkqubo yasemva konyango, izinto ezifakwe i-asphalt zenzelwe umxube we-asphalt, ifayibha nganye igqunywe ngokupheleleyo nge-asphalt inomgangatho ophezulu wokuhambelana, ngaloo ndlela kuqinisekiswa ukuba i-basalt fiber geogrid kumaleko we-asphalt ayizukuhlukaniswa nomxube we-asphalt, kodwa idityaniswe ngokuqinileyo.
Ukuqhekeka okuchasene nokudinwa: i-basalt geogrid kumaleko womphezulu we-asphalt, inokuba luxinzelelo lwamavili phezu komphezulu wendlela kunye nokusasazeka koxinzelelo oluxinzelelweyo noluxineneyo, ukwakheka kwendawo ye-buffer phakathi kweendawo ezimbini zoxinzelelo, utshintsho oluthe ngcembe loxinzelelo endaweni yotshintsho olukhawulezileyo, ukunciphisa utshintsho olukhawulezileyo loxinzelelo kumaleko womphezulu we-asphalt womonakalo. Kwangaxeshanye, ukwandiswa okuphantsi kwe-basalt geogrid kunciphisa ukugoba kwendlela, ukuqinisekisa ukuba indlela ayizukubakho ukuguquguquka okugqithisileyo.
I-rutting enganyangekiyo kubushushu obuphezulu: ukusetyenziswa kwe-basalt geogrid kumaleko we-asphalt, edlala indima yamathambo kumaleko we-asphalt. Hlanganisa ikhonkrithi ye-asphalt ngegridi, wenze inkqubo yokutshixa yoomatshini edibeneyo, unciphise intshukumo yee-aggregates, wonyusa amandla okubopha anqamlezileyo kumaleko womphezulu we-asphalt, umaleko womphezulu we-asphalt wenxalenye nganye yomnye, uthintele umaleko womphezulu we-asphalt wokutyhala ukuba udlale indima yokumelana ne-rutting.
Ukuqhekeka kobushushu obuphantsi okuchasene nokuqhekeka: kwiimeko zobushushu obuphantsi, ukuqhekeka okubandayo kwekhonkrithi ye-asphalt, okubangela uxinzelelo lokuxinana, xa uxinzelelo lokuxinana ludlula amandla okuxinana kwekhonkrithi ye-asphalt, okubangela ukuqhekeka. I-Basalt geogrid ekusebenziseni umaleko womphezulu we-asphalt, iphucula umaleko womphezulu wamandla okuxinana anqamlezileyo, ukuze amandla okuxinana kwekhonkrithi ye-asphalt aphuculwe kakhulu, inokumelana noxinzelelo olukhulu lokuxinana ngaphandle komonakalo. Ukongeza, nokuba ngenxa yendawo yengingqi yeemfanta, kwiindawo eziqhekekileyo ezenzekayo uxinzelelo lokuxinana, ngokudluliselwa kwe-basalt geogrid kwaye inyamalale, iimfanta aziyi kukhula zibe ziimfanta.
Ukulibaziseka kokunciphisa iintanda ezikhanyayo: kwi-asphalt ene-basalt geogrid flat layer, kuthintela ukucheba okanye uxinzelelo lokutsalwa olubangelwa yimithwalo yezithuthi, kukhulula uxinzelelo, njengezinto zokuqinisa ukutsalwa kwekhonkrithi ye-asphalt, ukufezekisa injongo yokulibaziseka kokunciphisa iintanda.

3. Ukusetyenziswa kwe-geogrid kunye nefayibha esisiseko
I-Geogrid ekusetyenzisweni kwezinto eziphambili ezifunekayo ukuze kuqiniswe amandla, ukumelana nokukrazuka, kunye nokudibanisa umhlaba, ukuqina kunye noqoqosho lwawo. Okwangoku, i-geogrid isetyenzisiwe kwicandelo lendlela yendlela, i-roadbed kaloliwe, i-land embankment, ukuphucula i-bank slope, inkxaso kunye nolwakhiwo lokugcina, ukulungiswa kwe-rock fracture layer, ukulungiswa kokuphuculwa kwe-pavement kunye nokuthintela kunye nokulawula ii-reflection crack. Ingakumbi ukusetyenziswa kwe-geogrid ekuphuculweni kwe-pavement kunye nokuthintela ii-reflection crack. I-reflection crack linqanaba le-road grass-roots ngenxa yokutshintsha kobushushu okanye umthwalo othwala kakhulu kwaye uvelisa ii-cracks, kwaye ngokusasazeka koxinzelelo lwe-interlayer kumphezulu wendlela, kuvelisa intshukumo ethe nkqo okanye ethe tye phakathi kwee-layer kwaye kwenze umphezulu wendlela uqhekeke. Ukusetyenziswa kwe-geogrid esebenza kakhulu kunokuphucula ngempumelelo amandla okucheba phakathi kwee-layer kunye nokusebenza kokudinwa kwendlela, kuchithachithe uxinzelelo loxinzelelo, ngaloo ndlela kuthintele ngempumelelo ukwenzeka kwee-pavement crack, kwaye kunciphise kakhulu iindleko zokugcinwa kwendlela. I-reflection crack yinto exhaphakileyo kwi-asphalt pavement. Kwimingxunya yokuqaqambisa kumphezulu wendlela, ukubeka umaleko we-geotextile phakathi komphezulu we-asphalt kunye ne-underlayment kunokususa okanye kunciphise ukuveliswa kwemingxunya yokuqaqambisa kumphezulu we-asphalt, ngaloo ndlela kwandise ubomi bendlela. Kodwa i-asphalt pavement ithulula ubushushu ukuya kwi-160 ℃, okubangela ukuba i-geotextile okanye i-polymer geogrid igobe, i-deformation, ithambe, ukuze ukusebenza kwayo kunciphe kakhulu. Ukusetyenziswa kwi-asphalt pavement geogrid kungcono ukusebenzisa i-basalt fiber geogrid, kuba i-basalt fiber geogrid inokumelana okuhle nobushushu, kunye namandla aphezulu, i-modulus ephezulu, i-elongation ephantsi, i-coefficient ephantsi yokwandiswa kobushushu kunye nezinye iimpawu.
