Basalt fiber geogrid kuita uye kuvaka
Properties of Basalt Fiber Geogrid
(1)High Breaking Strength: Simba rekuputsika rebasalt fiber geogrid muzvose zviri zviviri warp (longitudinal) uye weft (transverse) nzira dzakakwirira kudarika dzegirazi faibha geogrid pasi pemutsetse wakafanana density.
(2)Low Elongation: Iyo yekutyora kurebesa kwebasalt fiber geogrid mune warp uye weft nzira ndeye ≤3%.
(3)Yakanakisa Muviri uye Chemical Kugadzikana: Basalt fiber pachayo inoratidza kuramba kwakasimba kune acids, alkalis, uye corrosion. Iyo geogrid inogona kumira nekukukurwa kwemakemikari, kubvongodzwa kwemuviri, shanduko yemamiriro ekunze, uye kuparara kwebiological pasina kurasikirwa kwekuita.
(4)Creep Resistance: Basalt faibha, sechinhu chekusimbisa, haiitike zvinokambaira. Kukwanisa kwayo kupikisa deformation pasi pemitoro yenguva refu inovimbisa kuchengetedza kwekuita kwenguva refu.
(5)High-Temperature Resistance: Mushure mekupisa pa 170 ° C kweawa imwe, iyo yakachengetwa yakasimba yekupwanya simba mune warp uye weft nzira inoramba iri ≥90%.
(6)Low-Temperature Resistance: Mushure mechando pa -40 ° C kweawa imwe, iyo yakachengetwa yakasimba yekutyora simba muwarp uye weft nzira inoramba iri ≥80%.
(7)Aggregate Interlocking uye Restriction: Iwo maviri-dimensional gidhi chimiro cheiyo geogrid mechanically interlocks uye inorambidza kufamba kweasphalt mix aggregates. Pasi pemutoro, izvi zvinowedzera kutakura mutoro, inovandudza compaction, inogonesa kutamisa mutoro, uye inoderedza deformation.
Zvakanakira zveBasalt Fiber Geogrid muAsphalt Pavements
Asphalt-yakavharwa basalt fiber geogrid inowedzera hupenyu hwekuneta kwezvimiro zvepavement, inoderedza mitengo, uye inokwirisa mabhajeti einjiniya. Izvi zvinokonzerwa nekugona kwayo kurambidza kupararira kwe crack, kuwedzera kuramba kutadza kuchinjika kweshear, uye kubvisa crack simba zvinobudirira. Nekuwedzera kwehuwandu hwemotokari uye mitoro yemotokari, nzira dzinotarisana nekukuvara kwakanyanya, kunyanya nekuda kwemota dzakakura. Reflective cracking in asphalt overlays on old pavements inoramba iri nyaya yakaoma. Nepo mitswe inopenya pachayo isingakanganise mashandiro epavement nekukurumidza, zvinhu zvezvakatipoteredza (semuenzaniso, guruva, hunyoro, oxidation) inomhanyisa kuwedzera kwekuputika, kupfupisa hupenyu hwepamusoro. Basalt fiber geogrids inodzikamisa izvi nekugoverazve kushushikana, kuvandudza simba rekusimba, kunonoka kuputika, uye kurebesa hupenyu hwesevhisi.
Kuvaka Nzira dzeBasalt Fiber Geogrid muAsphalt Pavements
(1)Binder Selection: Shandisa kukurumidza-kugadzika emulsified asphalt kana yepakati-/kukurumidza-kurapa mvura asphalt yejasi retack.
(2)Installation Zvinodiwa: Ita shuwa kuti hwaro hwepasi hwakati sandara, compact, uye yakachena. Isa geogrid zvakanaka pasina kupindirana, kupeta, kana kumonyoroka. Anopindirana adjacent geogrids ne0.3 m akachinjika, achiabatanidza 1.5 m yega neNo. 8 waya dzesimbi. Chengetedza geogrid pasi nezvipikiri zvakaita U-zvakaparadzana 1.3-2 m.
(3)Kugadzirira Kwepamusoro: Bvisa zvinosvibisa (semuenzaniso, guruva, mafuta, unyoro) kuti uwedzere kubatana. Isa tack jasi emulsified asphalt zvishoma mushure mekurapa kuzere. Rongedza mvura inonyungudika ichidzika pasi panguva yekuisa.
(4)Kupindirana Zvinotsanangurwa: Longitudinal overlaps inofanira kuva ≥20 cm, uye transverse overlaps ≥15 cm. Isa iyo geogrid inotangira pamusoro peinotevera munzira yeasphalt paving. Dzivisa kuroverera zvakananga mugeogrid kana kuirova nesando. Gadzirisazve zvipikiri zvisina kusimba kana ndiro. Mushure mekuisirwa, zvinyoro nyoro geogrid nerubha-vhiri roller kuti uve nechokwadi chekunamira.
(5)Kupindirana Kwenguva: Kutenderedza pakarepo kunoderedza kuumbwa kwemafungu. Kudzora kwemhando yepamusoro uye vashandi vane hunyanzvi zvakakosha pakuita kwakaringana.
Mhedziso
(1) Basalt fiber geogrid inodarika akajairwa ma geogrids ane yakakwira modulus, simba, kudzika kwakadzika, kutsemuka kuramba, kuchembera/kutura kuramba, uye customizable dhizaini, zvichiita kuti ive yakanakira mainjiniya emigwagwa.
(2) Kushandiswa kwayo kunoderedza kuwanda kwekuvaka, kunowedzera kufambira mberi, uye kunoderedza mari.
(3) Inoderedza mari yekugadzirisa uye inowedzera asphalt pavement hupenyu hurefu.
