Nhanganyaya ku basalt fiber geogrids

1.Tsananguro yefayibha yebasalt geogrid
Basalt geogrid Yakasarudzwa basalt fiber shinda, kushandiswa kwemuchina wekuruka wemhando yepamusoro we warp wakarukwa mu substrate, kushandiswa kwe warp knitting directional structure, kushandisa zvizere jira riri musimba reshinda, kuvandudza hunhu hwaro hwemakanika, kuitira kuti rive nesimba rakanaka rekudhonza, simba rekubvaruka uye kuramba kukambaira, uye mushure me asphalt yakagadziriswa yepamusoro-soro yakafukidzwa ne planar network yezvinhu. Inotevera musimboti wekuenderana kwakafanana, ichitarisa pakushanda kwayo kwakabatana nemusanganiswa we asphalt, uye inodzivirira zvizere fiber substrate, ichivandudza zvakanyanya kuramba kwekukwesha uye kuramba kuchekwa kwe substrate, kuitira kuti igone kushandiswa pakuvandudza nzira, kuramba kutsemuka kwenzira uye dzimwe njodzi dzemugwagwa, uye kugumisa nzira ye asphalt kwakaoma kuwedzera dambudziko.

2. Hunhu hwe fibre geogrid yekutanga

• Chigadzirwa ichi chine zvakanakira zve Simba Rakakwirira, kureba kwakaderera, kuramba kupisa kwakanyanya, modulus yakakwira, huremu hwakareruka, kusimba kwakanaka, kuramba ngura, hupenyu hwebasa hurefu, nyore kuisa, nezvimwewo, zvinogona kushandiswa zvakanyanya mumigwagwa yekare yesimende, kugadziriswa kwenhandare yendege, embankment, rwizi, dziviriro yemateru, kurapwa kwekuvandudza migwagwa nemabhiriji nedzimwe nzvimbo dzeinjiniya, zvinogona kupa migwagwa kuti iwedzere kusimbiswa, kusimbisa, kudzivirira kuneta kwemakumbo mumakombama, kuwedzera kupisa nekutonhora uye kupwanyika kwemakombama uye kupatsanuka kunotevera, uye Inogona kuparadzira kushushikana kwekutakura migwagwa uye kuwedzera hupenyu hwebasa remigwagwa.
• Simba guru rekudhonza uye kureba kushoma: basalt fiber geogrid yakavakirwa pabasalt fiber sezvinhu zvakabikwa, uye basalt fiber simba rekudhonza rakakwira zvikuru, kupfuura mamwe mafiber nesimbi yakajairika. Panguva imwe chete ine modulus yakakwira, inodzivirira zvakanyanya kuchinjika, kureba kwekutyoka kuri pasi pe3%.
• Hapana kukambaira kwenguva refu: sechinhu chinosimbisa, nekukwanisa kuramba kukanganisika kana mutoro wenguva refu, kuramba kukambaira kwakakosha zvikuru, basalt fiber haizokambairi, kuve nechokwadi chekuti chigadzirwa chinogona kuchengetedza kushanda kwenguva refu.
• Kugadzikana kwakanaka kwazvo mumuviri uye mumakemikari: basalt fiber pachayo inodzivirira zvikuru ngura yeasidhi nealkali, basalt geogrid inogona kuramba kushandiswa kwakasiyana-siyana uye kuparadzwa kwemakemikari, asiwo inodzivirira kuparadzwa kwezvipenyu uye kushanduka kwemamiriro ekunze, kuitira kuti ishande zvakanaka.
• Kugadzikana kwakanaka kwekupisa: nzvimbo yekunyunguduka kwebasalt fiber mu 1500 ° C kana kupfuura, kushandiswa kwenguva refu kwekushisa pakati pe -260 ° ~ 650 °, kuve nechokwadi chekuti basalt geogrid mukushanda kwekugadzira mapani kuti agone kugadzikana pakupisa kwakanyanya.
• Kuunganidzwa kwekiyi yakavharirwa uye kudziviswa: nekuti basalt geogrid Chimiro che mesh, kongiri yeasphalt mu aggregate inogona kupinzwa, kuitira kuti kuumbwa kwekiyi yakavharirwa nemechanical. Kudziviswa uku kunotadzisa kufamba kwe aggregate, kuitira kuti musanganiswa weasphalt kana uri mutoro uwane mamiriro ari nani ekumanikidzwa, kugona kwakakwirira kwekutakura mutoro, kushanda kuri nani kwekutakura mutoro uye kusachinja-chinja.
• Uye kuenderana kwemusanganiswa weasphalt: basalt geogrid mushure mekurapwa, zvinhu zvakaputirwa zvakagadzirirwa musanganiswa weasphalt, fiber yega yega yakazara neasphalt ine mwero wepamusoro wekuenderana, nokudaro ichivimbisa kuti basalt fiber geogrid iri muasphalt layer haizoparadzanisirwi nemusanganiswa weasphalt, asi inobatanidzwa zvakasimba pamwe chete.
• Kupwanya kwepasi pevhu: basalt geogrid iri mu asphalt surface layer, inogona kunge iri kumanikidzwa kwemavhiri pamusoro pemugwagwa uye kupararira kwekumanikidzwa nekumanikidzwa, kuumbwa kwenzvimbo yekudzivirira pakati penzvimbo mbiri dzekumanikidzwa, kuchinja zvishoma nezvishoma kwekumanikidzwa pane kuchinja kamwe kamwe, kuderedza kuchinja kamwe kamwe kwekumanikidzwa pamusoro pe asphalt surface layer yekukuvadzwa. Panguva imwe chete, kureba kushoma kwe basalt geogrid kunoderedza kukotama kwemugwagwa, zvichiita kuti pavement isazove nekushanduka kwakanyanya.
• Rutting inotsungirira kupisa kwakanyanya: kushandiswa kwebasalt geogrid mu asphalt layer, iyo inoita basa remapfupa mu asphalt layer. Unganidza kongiri yeasphalt kuburikidza negrid, uchigadzira system yekukiya yemuchina, uchidzikamisa kufamba kwe aggregates, uchiwedzera simba rekusunga rakachinjika mu asphalt surface layer, asphalt surface layer yechikamu chimwe nechimwe cheumwe neumwe, uchidzivirira asphalt surface layer yekusundidzira kuti iite basa rekudzivirira rutting.
• Kupwanya kweAnti low tembiricha: mumamiriro ekunze ekupisa kwakaderera, asphalt concrete inotonhora inopwanya, zvichikonzera tensile stress, kana tensile stress ikapfuura tensile strength yeasphalt concrete, zvichikonzera cracks. Basalt geogrid pakushandisa asphalt surface layer, inovandudza pamusoro pe transverse tensile strength, kuitira kuti tensile strength yeasphalt concrete ive nani zvikuru, inogona kuramba tensile stress yakakura pasina kukuvara. Pamusoro pezvo, kunyangwe nekuda kwenzvimbo yemuno yemacracks, mucracks kuitika stress concentration, ne basalt geogrid kutamiswa uye kunyangarika, macracks haazokure kuita macracks.
• Kunonoka kudzikiswa kwemitsara inopenya: muasphalt ine basalt geogrid flat layer, kudzikamisa kusvuta kana kushushikana kunokonzerwa nemitoro yemota, kusunungura kusvuta, seasphalt concrete yekusimbisa kusimba, kuti kuzadzisa chinangwa chekunonotsa kudzikiswa kwemitsara.

3. Kushandiswa kwe geogrid ne fiber yekutanga
Geogrid mukushandiswa kwezvinhu zvikuru zvine chekuita nesimba, kudzivirira kubvaruka, uye musanganiswa wevhu, kugara kwenguva refu uye hupfumi hwaro. Parizvino, geogrid yave ichishandiswa mumunda wemugwagwa mukuru, njanji, soil embankment, bank slope enhancement, support and retaining structure, rock fracture layer repavement ... Kune mitswe yekuratidzira pamusoro pemugwagwa, kuisa jira re geotextile pakati pejira re asphalt ne underlayment kunogona kubvisa kana kunonoka kugadzirwa kwemitswe yekuratidzira pamusoro pejira, nokudaro kuwedzera hupenyu hwebasa remugwagwa. Asi asphalt pavement ichidira tembiricha kusvika 160 ℃, zvichikonzera geotextile kana polymer geogrid fold, deformation, softening, zvekuti mashandiro ayo akaderera zvikuru. Kushandiswa mu asphalt pavement geogrid kwakanakisa kushandisa basalt fiber geogrid, nekuti basalt fiber geogrid ine kupisa kwakanaka, uye ine simba rakawanda, high modulus, low elongation, low coefficient of thermal expansion nezvimwe zvinhu.
