Nhanganyaya kune basalt fiber geogrids

1.Tsanangudzo yebasalt fiber geogrid
Basalt geogrid inosarudzwa basalt fiber yarn, kushandiswa kwekunze kwepamberi warp knitting muchina wakarukwa mu substrate, kushandiswa kwewarp knitting directional chimiro, shandisa zvizere jira musimba reshinda, kuvandudza maitiro ayo emuchina, kuitira kuti ive nesimba rakanaka rekusimba, kubvarura simba uye kukambaira, uye mushure memhando yepamusoro yakagadziridzwa asphalt yakavharwa ne planar network yezvinhu. Inoteedzera musimboti wekuenderana kwakafanana, ichitarisa pakuita kwayo kwakaumbwa nemusanganiswa weasphalt, uye kudzivirira zvizere iyo fiber substrate, kuvandudza zvakanyanya kushivirira kweabrasion uye kushorwa kweshear kweiyo substrate, kuitira kuti igone kushandiswa kukwidziridza nzira, kuramba kupaza rutting uye dzimwe njodzi dzemumugwagwa, uye kumisa iyo asphalt pavement yakaoma kusimudzira dambudziko.

2.Unhu hweiyo yakakosha fiber geogrid

• Chigadzirwa chine zvakanakira High Strength, kureba kwakadzika, kupisa kwekushisa kwepamusoro, modulus yakakwira, huremu huremu, kusimba kwakanaka, kuramba kwemarara, hupenyu hurefu hwesevhisi, nyore kukwana, nezvimwewo, inogona kushandiswa zvakanyanya mune yekare simende pavement, nhandare yenhandare yendege kugadzirisa, kumisa, kumahombekombe erwizi, kuchengetedzwa kwemateru, mugwagwa uye bhiriji nzira yekuvandudza nzira uye dzimwe minda yeinjiniya, inogona kupa kusimbaradza, kusimbaradza, kusimbaradza nzira kuneta kunotsemuka munzira, kupisa uye kutonhora kwekuwedzera uye kuputika kutsemuka uye kunotevera kunoratidzira kuputika, uye Inogona kuparadzira nzira inotakura kushushikana uye kurebesa hupenyu hwebasa repavhu.
• Kusimba kwakanyanya uye kuderera kwakadzika: basalt fiber geogrid yakavakirwa pabasalt faibha seyakagadzirwa, uye basalt fiber tensile simba rakakwira zvakanyanya, kupfuura mamwe mafibhi nesimbi zvakajairika. Panguva imwecheteyo ine yakakwira modulus, ine yakanyanya kuramba deformation, kutsemuka kurebesa kuri pasi pe3%.
• Hapana kukambaira kwenguva refu: sechinhu chinosimbisa, nekwaniso yekuramba deformation mune yenguva refu mitoro iyo inokambaira kuramba yakakosha zvakanyanya, basalt fiber haifambe, kuve nechokwadi chekuti chigadzirwa chinogona kuchengetedza kushanda kwenguva refu.
• Yakanakisa kugadzikana kwemuviri uye kemikari: basalt fiber pachayo ine kupikisa kwakasimba kune acid uye alkali corrosion, basalt geogrid inogona kuramba zvakasiyana-siyana zvekupfeka kwemuviri uye kuputika kwemakemikari, asiwo nekupokana nekukukurwa kwebiological uye kushanduka kwemamiriro ekunze, kuve nechokwadi kuti kuita kwayo hakuna kurasika.
• Kugadzikana kwakanaka kwekushisa: basalt fiber inonyungudika mu1500 ° C kana kupfuura, kushandiswa kwenguva refu kwekushisa pakati -260 ° ~ 650 °, kuve nechokwadi kuti basalt geogrid mukushanda kwepaving kutsungirira kugadzikana kwekushisa kwepamusoro.
• Iyo yakaunganidzwa yekiyi yakamisikidzwa uye kudziviswa: nekuti iyo basalt geogrid iri mesh chimiro, asphalt kongiri mune aggregate inogona kupinzwa, kuitira kuti kuumbwa kweiyo mechanical embedded lock. Kurambidzwa uku kunotadzisa kufamba kweaggregates, kuitira kuti asphalt musanganiswa munyaya yekuremerwa inogona kuwana zviri nani mamiriro ekugadzirisa, kukwirira kwekutakura mutoro, kushanda kwekutakura kwekutakura uye kushoma deformation.
• Uye asphalt musanganiswa kuenderana: basalt geogrid mushure mekurapa maitiro akaputirwa zvinhu zvakagadzirirwa kusanganiswa kweasphalt, fiber imwe neimwe yakanyatsoputirwa neasphalt ine hupamhi hwekuenderana, nokudaro kuve nechokwadi chokuti basalt fiber geogrid mu asphalt layer haizoparadzaniswa kubva kune asphalt musanganiswa, asi yakanyatsobatanidzwa pamwe chete.
• Kupokana-kuneta: basalt geogrid muasphalt pamusoro pedenga, inogona kuve vhiri kumanikidza pamusoro pemugwagwa uye inokonzeresa yekumanikidza uye kusagadzikana kusagadzikana kupararira, kuumbwa kwenzvimbo yebuffer pakati penzvimbo mbiri dzekushushikana, kushanduka zvishoma nezvishoma kwekushushikana kwete kungoerekana chinja, kuderedza kungoerekana kushanduka kwekushushikana paasphalt pamusoro pekukuvara. Panguva imwecheteyo, iyo yakaderera elongation yebasalt geogrid inoderedza kukotama kwegwagwa, kuve nechokwadi kuti iyo nzira haizoitike yakawandisa deformation.
• High-temperature resistant rutting: kushandiswa kwebasalt geogrid muasphalt layer, iyo inobata skeleton basa muasphalt layer. Aggregate mu asphalt kongiri kuburikidza negridi, ichigadzira inoumbwa mechanicha yekuvhara sisitimu, inodzikamisa kufamba kweaggregates, ichiwedzera inochinjika inosunga simba muasphalt pamusoro pedenga, asphalt pamusoro pechikamu chimwe nechimwe cheumwe neumwe, kudzivirira iyo asphalt pamusoro pedhiri yekusundidzira kutamba basa rekuramba rutting.
• Anti yakaderera tembiricha shrinkage kuparuka: mune yakaderera tembiricha mamiriro, asphalt kongiri inotonhora shrinkage, zvichikonzera kushushikana kwekunetseka, apo kushushikana kwekunetseka kunodarika simba rekusimba reasphalt kongiri, zvichikonzera kutsemuka. Basalt geogrid mukushandiswa kweasphalt pamusoro pedenga, inonatsiridza iyo pamusoro peiyo transverse tensile simba, kuitira kuti kusimba kwesimba reasphalt kongiri kugadziriswe zvakanyanya, inogona kuramba yakakura tensile kusagadzikana pasina kukuvara. Mukuwedzera, kunyange kana nekuda kwenzvimbo yemunharaunda yekutsemuka, mumitsero inoitika kushushikana kwepfungwa, ne basalt geogrid transfer and disappear, kuputika hakuzogadziri kuva kuputika.
• Kunonoka kuderedzwa kweanoratidzira matsemuka: muasphalt ine basalt geogrid flat layer, inhibit shear kana tensile kusagadzikana kunokonzerwa nekuremerwa kwemotokari, kusunungura kuomarara, seasphalt kongiri inosimbisa zvinhu zvekusimbisa, kuzadzisa chinangwa chekunonoka kuderedzwa kwekutsemuka.

3.Kushandiswa kwegeogrid ine fiber inokosha
Geogrid mukushandiswa kwezvinonyanya kufunga nezvesimba, kuramba kubvarura, uye kusanganiswa kwevhu, kusimba uye hupfumi hwayo. Parizvino, geogrid yakashandiswa mumunda wemugwagwa wemugwagwa, njanji yemugwagwa, kusungirirwa kwevhu, kukwidziridzwa kwebhengi kutsetseka, kutsigirwa uye kuchengetedza chimiro, dombo rakaputsika dhizaini kugadzirisa, kukwidziridzwa kwepavement uye kuratidzira kudzivirira uye kutonga. Kunyanya kushandiswa kwegeogrid mukusimudzira nzira uye kudzivirira kwekutsvuka kwekuratidzira. Reflection crack ndiyo nzira yehuswa-midzi yemugwagwa nekuda kwekuchinja kwekushisa kana kutakurwa kwemutoro wakakura zvakanyanya uye kuburitsa mitswe, uye kuburikidza ne interlayer stress propagation kusvika kumusoro kwemugwagwa, gadzira vertical or horizontal movement pakati peturu uye kuita kuti mugwagwa uparare. Kushandiswa kwepamusoro-kushanda geogrid kunogona kunyatso kuvandudza simba rekucheka kwemukati uye kukotamisa kuneta kushanda kwemugwagwa, kuparadzira kushushikana kwepfungwa, nokudaro kudzivirira zvinobudirira kuitika kwekutsemuka kwemugwagwa, uye kuderedza zvakanyanya mari yekugadzirisa mugwagwa. Reflection cracking chiitiko chinowanzo kuwanikwa mu asphalt pavement. Kune iyo ratidziro yakatsemuka munzira yemugwagwa, kuisa dhizaini ye geotextile pakati peasphalt pamusoro pedenga uye underlayment inogona kubvisa kana kudzikamisa chizvarwa chekuratidzira kutsemuka muchikamu chepamusoro, nekudaro kuwedzera hupenyu hwebasa remugwagwa. Asi asphalt pavement inodurura tembiricha inosvika 160 ℃, zvichikonzera geotextile kana polymer geogrid peta, deformation, kupfava, kuitira kuti kuita kwayo kuderedzwa zvakanyanya. Inoshandiswa muasphalt pavement geogrid inonyanya kushandisa basalt fiber geogrid, nokuti basalt fiber geogrid ine yakanaka kupisa kupisa, uye simba guru, yakakwirira modulus, yakaderera elongation, yakaderera coefficient yekuwedzera kwekushisa uye mamwe maitiro.
