Isingeniso ku-basalt fiber geogrids

1.Incazelo ye-basalt fiber i-geogrid
I-Basalt geogrid kukhethwa intambo ye-basalt fiber, ukusetshenziswa komshini wokunitha we-warp othuthukisiwe wangaphandle owelukwe ku-substrate, ukusetshenziswa kwe-warp ukunitha isakhiwo esiqondisayo, sebenzisa ngokugcwele indwangu emandleni entambo, ukuthuthukisa izakhiwo zayo zemishini, ukuze ibe namandla amahle okudonsa, amandla okudabula kanye nokumelana nokukhasa, futhi ngemva kwe-asphalt eguquliwe yezinga eliphezulu ehlanganiswe nenethiwekhi yezinto ezibonakalayo. Ilandela isimiso sokuhambisana okufanayo, igxile ekusebenzeni kwayo okuyinhlanganisela nge-asphalt ingxube, futhi ivikele ngokugcwele i-fiber substrate, ithuthukise kakhulu ukumelana nokuhuzuka kanye nokumelana kwe-shear ye-substrate, ukuze isetshenziselwe ukuthuthukiswa komgwaqo, ukumelana nokuqhekeka kwe-rutting nezinye izingozi zomgwaqo, futhi uqede umgwaqo we-asphalt kunzima ukuthuthukisa inkinga.

2.Izici ze-fiber geogrid eyisisekelo

• Umkhiqizo unezinzuzo ze Amandla Aphakeme, ubude obuphansi, ukumelana nokushisa okuphezulu, i-modulus ephezulu, isisindo esilula, ukuqina okuhle, ukumelana nokugqwala, impilo ende yesevisi, ukulingana kalula, njll., kungasetshenziswa kabanzi endaweni egandaywe wusimende endala, ukugcinwa komgwaqo wezindiza zezindiza, uthango, usebe lomfula, ukuvikelwa komthambeka, ukwelashwa kokuthuthukiswa komgwaqo kanye nebhuloho kanye nezinye izinkambu zobunjiniyela, kunganikeza ukugaywa komgwaqo ukuze kuvimbele ukugaywa kwemigwaqo, ukuvimbela ukugaywa kwemigwaqo, ukuvimbela ukugaywa kwemigwaqo ukukhathala ukuqhekeka ku-pavement, ukushisa nokubanda ukunwetshwa kanye nokuqhekeka okufinyezwayo kanye nokuqhekeka okubonakalayo okulandelayo, futhi Kungahlakaza umgwaqo othwele ingcindezi futhi kwelule impilo yesevisi yendawo egandaywayo.
• Amandla aqinile aphezulu kanye nobude obuphansi: i-basalt fiber geogrid isekelwe ku-basalt fiber njengempahla eluhlaza, futhi amandla e-basalt fiber tensile aphakeme kakhulu, ngaphezu kweminye imicu nensimbi evamile. Ngesikhathi esifanayo ine-modulus ephezulu, inokumelana okuphezulu nokuguqulwa, ukuphakama kwe-fracture kungaphansi kuka-3%.
• Akukho ukuhamba kwesikhathi eside: njengento eqinisayo, enekhono lokumelana ne-deformation esimweni somthwalo wesikhathi eside ukuthi ukumelana ne-creep kubaluleke kakhulu, i-basalt fiber ngeke ihambe, ukuqinisekisa ukuthi umkhiqizo ungagcina ukusebenza kwesikhathi eside.
• Ukuzinza okuhle ngokomzimba namakhemikhali: i-basalt fiber ngokwayo inokumelana okuqinile ne-asidi nokugqwala kwe-alkali, i-basalt geogrid ingakwazi ukumelana nokuguga okuhlukahlukene ngokomzimba nokuguguleka kwamakhemikhali, kodwa futhi ngokumelene nokuguguleka kwezinto eziphilayo kanye nokushintsha kwesimo sezulu, ukuqinisekisa ukuthi ukusebenza kwayo akulahleki.
• Ukuzinza okuhle kokushisa: indawo yokuncibilika ye-basalt fiber ku-1500 ° C noma ngaphezulu, ukusetshenziswa kwesikhathi eside kwezinga lokushisa phakathi -260 ° ~ 650 °, ukuqinisekisa ukuthi i-basalt geogrid emsebenzini wokugandaya ukuze umelane nezinga lokushisa eliphezulu.
• Isamba sesikhiya esishumekiwe kanye nomkhawulo: ngoba i i-basalt geogrid iyisakhiwo se-mesh, ukhonkolo we-asphalt ku-aggregate ungangena, ukuze ukwakheka kokukhiya okufakwe ngomshini. Lo mkhawulo uvimbela ukunyakaza kwama-aggregates, ukuze ingxube ye-asphalt esimweni somthwalo ikwazi ukufeza isimo esingcono sokuhlanganisa, umthamo ophezulu wokuthwala umthwalo, ukusebenza okungcono kokudlulisa umthwalo kanye nokuguqulwa okuncane.
• Futhi ukuhambisana kwengxube ye-asphalt: i-basalt geogrid enkambweni yokwelashwa emva kokwelashwa izinto eziboshwe zenzelwe ingxube ye-asphalt, i-fiber ngayinye ehlanganiswe ngokugcwele ne-asphalt inezinga eliphezulu lokuhambisana, ngaleyo ndlela iqinisekisa ukuthi i-basalt fiber geogrid kungqimba lwe-asphalt ngeke ihlukaniswe nengxube ye-asphalt, kodwa ihlanganiswe ngokuqinile ndawonye.
• Ukuqhekeka okulwa nokukhathala: i-basalt geogrid endaweni ye-asphalt surface, ingaba ingcindezi yamasondo phezu komgwaqo kanye nomphumela wokuhlakazeka kokucindezeleka okucindezelwayo, ukwakheka kwendawo ye-buffer phakathi kwezindawo ezimbili zokucindezeleka, ukuguquka kancane kancane kokucindezeleka kunokushintsha okungazelelwe, kunciphisa ukushintsha okungazelelwe kokucindezeleka ongqimbeni lwe-asphalt lomonakalo. Ngesikhathi esifanayo, ukuphakama okuphansi kwe-basalt geogrid kunciphisa ukugoba kwendlela egandayiwe, iqinisekisa ukuthi umgwaqo ngeke wenzeke ukuwohloka ngokweqile.
• I-rutting ukumelana nokushisa okuphezulu: ukusetshenziswa kwe-basalt geogrid kungqimba lwe-asphalt, edlala indima yamathambo ongqimba lwe-asphalt. Hlanganisa ukhonkolo we-asphalt ngokusebenzisa igridi, wenze uhlelo lokukhiya oluyinhlanganisela, unciphise ukunyakaza kwama-aggregate, ukhulise amandla abophayo anqamula ungqimba lwe-asphalt surface, ungqimba lwe-asphalt ebusweni bengxenye ngayinye kwenye, ukuvimbela ungqimba lwe-asphalt ebusweni bokucindezela ukudlala indima yokumelana nokurutha.
• Ukuqhekeka kwe-Anti low lokushisa shrinkage: ezimweni zokushisa eziphansi, ukuncibilika okubandayo kokhonkolo we-asphalt, okuholela ekucindezelekeni okuqinile, lapho ukucindezeleka okuqinile kudlula amandla aqinile kakhonkolo we-asphalt, okuholela ekuqhekekeni. I-Basalt geogrid ekusebenziseni ungqimba lwe-asphalt surface, ithuthukisa ungqimba lwangaphezulu lwamandla aguquguqukayo aqinile, ukuze amandla aqinile kakhonkolo we-asphalt athuthuke kakhulu, akwazi ukumelana nokucindezeleka okukhulu okuqinile ngaphandle kokulimala. Ngaphezu kwalokho, ngisho noma ngenxa yendawo yendawo yokuqhekeka, emifantwini eyenzeka ekugxilweni kokucindezeleka, ngokudluliswa kwe-basalt geogrid nokunyamalala, imifantu ngeke ikhule ibe imifantu.
• Ukuncishiswa kokulibaziseka kwemifantu ekhanyayo: ku-asphalt enongqimba oluyisicaba lwe-basalt geogrid, vimbela ukugunda noma ukuqina kwengcindezi okubangelwa ukugcwala kwezimoto, khulula ubunzima, njengezinto zokuqinisa ukuqina kokhonkolo we-asphalt, ukufeza inhloso yokubambezela ukuncishiswa kwemifantu.

3.Ukusetshenziswa kwe-geogrid enefayibha eyisisekelo
Geogrid ekusetshenzisweni kokucatshangelwa okuyinhloko kwamandla, ukumelana nezinyembezi, kanye nenhlanganisela yenhlabathi, ukuqina kanye nomnotho wayo. Njengamanje, i-geogrid isetshenziswe emkhakheni womgwaqo onguthelawayeka, umbhede wesitimela, uthango lwenhlabathi, ukuthuthukiswa komthambeka wasebhange, ukusekelwa nokugcina isakhiwo, ukulungiswa kongqimba lwamadwala, ukulungiswa komgwaqo ohamba ngezinyawo kanye nokuvimbela nokulawula ukuqhekeka okubonakalayo. Ikakhulukazi ukusetshenziswa kwe-geogrid ekuthuthukisweni kokugandaywa kwezinyawo nokuvimbela imifantu yokubona. I-Reflection crack izinga lezimpande zomgwaqo ngenxa yokushintsha kwezinga lokushisa noma umthwalo othwala umthwalo omkhulu kakhulu futhi ukhiqiza imifantu, futhi ngokusebenzisa ukusakazeka kokucindezeleka kwe-interlayer endaweni yomgwaqo, khiqiza ukunyakaza okuqondile noma okuvundlile phakathi kwezingqimba futhi kwenze umgwaqo uqhekeke. Ukusetshenziswa kwe-geogrid esebenza kahle kakhulu kungathuthukisa ngempumelelo amandla e-shear e-interlayer nokusebenza kokukhathala ogobayo komgwaqo, kuhlakaze ukugxiliswa kwengcindezi, ngaleyo ndlela kuvimbele ngempumelelo ukwenzeka kokuqhekeka komgwaqo, futhi kunciphise kakhulu izindleko zokulungisa umgwaqo. Ukuqhekeka kwe-reflection kuyinto evame ukutholakala endaweni egandaywe yitiyela. Ukuze uthole imifantu ekhanyayo ebusweni bomgwaqo, ukubeka ungqimba lwe-geotextile phakathi kwe-asphalt surface layer kanye ne-underlayment kungaqeda noma kubambezele isizukulwane sokuqhekeka kokubonisa kungqimba olungaphezulu, ngaleyo ndlela kunwebe impilo yesevisi yomgwaqo. Kodwa i-asphalt ithela izinga lokushisa elifika ku-160 ℃, okuholela ekugoqeni kwe-geotextile noma i-polymer geogrid, ukuguqulwa, ukuthambisa, ukuze ukusebenza kwayo kunciphe kakhulu. Kusetshenziswe ku-asphalt pavement geogrid kungcono kakhulu ukusebenzisa i-basalt fiber geogrid, ngoba i-basalt fiber geogrid inokumelana nokushisa okuhle, namandla aphezulu, i-modulus ephezulu, i-elongation ephansi, i-coefficient ephansi yokwanda okushisayo nezinye izici.
