Chiyambi cha basalt fiber geogrids

2025-02-13

1.Tanthauzo la ulusi wa basalt geogrid
Basalt geogrid amasankhidwa basalt CHIKWANGWANI ulusi, ntchito yakunja patsogolo warp kuluka makina nsalu mu gawo lapansi, ntchito warp kuluka dongosolo malangizo, ntchito mokwanira nsalu mu mphamvu ulusi, kusintha katundu wake makina, kuti ali ndi mphamvu kumakokedwa, misozi mphamvu ndi kukwawa kukana, ndipo pambuyo apamwamba kusinthidwa phula TACHIMATA ndi maukonde planar zipangizo. Imatsatira mfundo yofananira yofananira, kuyang'ana pakuchita kwake kophatikiza ndi kusakaniza kwa phula, ndikuteteza gawo lapansi la CHIKWANGWANI, kuwongolera kwambiri kukana kwa abrasion ndi kukana kukameta ubweya wa gawo lapansi, kotero kuti zitha kugwiritsidwa ntchito kupititsa patsogolo njira, kukana kusweka kwa rutting ndi zoopsa zina zapamsewu, ndikuthetsa njira ya phula ndizovuta kukulitsa vuto.

2.Makhalidwe a maziko a fiber geogrid

The mankhwala ali ubwino wa Mphamvu Zapamwamba, elongation otsika, mkulu kutentha kukana, modulus mkulu, kulemera kuwala, toughness zabwino, kukana dzimbiri, moyo wautali utumiki, zosavuta kugwirizana, etc., angagwiritsidwe ntchito ankagwiritsa akale miyala ya simenti, ndege kukonza msewu wonyamukira ndege, mpanda, mtsinje mtsinje, chitetezo otsetsereka, msewu ndi mlatho njira kuwongola mankhwala ndi minda ina zomangamanga, angapereke chilimbikitso, kulimbikitsa kulimbitsa, kupititsa patsogolo njira yolimbikitsira, kupititsa patsogolo njira yolimbikitsira. kutopa kumang'ambika munjira, kutentha ndi kuzizira kukulitsa ndi ming'alu yocheperako komanso kung'ambika kotsatiraku, ndipo Ikhoza kubalalitsa msewu womwe umakhala ndi nkhawa ndikutalikitsa moyo wautumiki wapanjira.
Kulimba kwamphamvu kwambiri komanso kutalika kochepa: basalt fiber geogrid imakhazikitsidwa ndi ulusi wa basalt ngati zopangira, ndipo mphamvu yamagetsi ya basalt ndiyokwera kwambiri, kuposa ulusi wina ndi chitsulo wamba. Pa nthawi yomweyi imakhala ndi modulus yapamwamba, imakhala ndi kukana kwakukulu kwa mapindikidwe, kutalika kwa fracture kumakhala kosakwana 3%.
Palibe kukwawa kwanthawi yayitali: ngati chinthu cholimbikitsa, chotha kukana kupindika pakatha nthawi yayitali kuti kukana kwapang'onopang'ono ndikofunikira kwambiri, ulusi wa basalt sudzayenda, kuwonetsetsa kuti mankhwalawa amatha kukhalabe ndi nthawi yayitali.
Kukhazikika kwabwino kwa thupi ndi mankhwala: CHIKWANGWANI cha basalt chokha chimakhala ndi kukana kwamphamvu kwa asidi ndi dzimbiri zamchere, basalt geogrid imatha kukana mavalidwe osiyanasiyana amthupi ndi kukokoloka kwamankhwala, komanso motsutsana ndi kukokoloka kwachilengedwe ndi kusintha kwa nyengo, kuonetsetsa kuti ntchito yake sitayika.
Kukhazikika kwabwino kwamafuta: basalt fiber melting point mu 1500 ° C kapena kupitilira apo, kugwiritsa ntchito kutentha kwanthawi yayitali pakati pa -260 ° ~ 650 °, kuonetsetsa kuti basalt geogrid mu ntchito yapaving kupirira bata mkulu kutentha.
Kuphatikizika kwa loko yophatikizidwa ndi zoletsa: chifukwa basalt geogrid ndi mauna dongosolo, phula konkire mu akaphatikiza akhoza analowerera, kuti mapangidwe makina ophatikizidwa loko. Kuletsa kumeneku kumalepheretsa kusuntha kwamagulu, kotero kuti kusakaniza kwa asphalt pa nkhani ya katundu kungathe kukwaniritsa bwino kwambiri, kunyamula katundu wambiri, ntchito yabwino yosamutsira katundu komanso kuchepa pang'ono.
Ndipo kusakanikirana kwa asphalt: basalt geogrid mu ndondomeko ya mankhwala pambuyo pa mankhwala ophimbidwa zida zapangidwa kuti zisakanize phula, ulusi uliwonse umakhala wokutidwa ndi phula uli ndi kuyanjana kwakukulu, motero kuonetsetsa kuti basalt fiber geogrid mu phula wosanjikiza sichidzasiyanitsidwa ndi kusakaniza kwa asphalt, koma molimba pamodzi.
Kulimbana ndi kutopa: basalt geogrid mu phula pamwamba wosanjikiza, akhoza kukhala gudumu kuthamanga pamwamba pa msewu ndi chifukwa compressive ndi kukanika kubalalitsidwa kupsinjika maganizo, mapangidwe malo otchinga pakati pa madera awiri opsinjika maganizo, kusintha pang'onopang'ono kupsyinjika m'malo mosintha mwadzidzidzi, kuchepetsa kusintha kwadzidzidzi kwa kupsyinjika pamtunda wa asphalt wa zowonongeka. Nthawi yomweyo, kutsika kotsika kwa basalt geogrid kumachepetsa kupindika kwanjira, kuwonetsetsa kuti njirayo sichitika mapindikidwe ochulukirapo.
Kutentha kosasunthika kwambiri: kugwiritsa ntchito basalt geogrid mu phula la asphalt, lomwe limagwira ntchito ya mafupa mu phula. Akaphatikiza mu phula konkire kudzera gululi, kupanga gulu makina locking dongosolo, kuchepetsa kayendedwe ka aggregates, kuonjezera yopingasa kumanga mphamvu mu phula pamwamba wosanjikiza, phula pamwamba wosanjikiza mbali iliyonse ya mzake, kuteteza phula pamwamba wosanjikiza wa kukankhira kuchita mbali ya kukana rutting.
Anti otsika kutentha shrinkage akulimbana: mu kutentha otsika, phula konkire ozizira shrinkage, kumabweretsa kupsyinjika wamanjenje, pamene kupanikizika kwamakomedwe kuposa kumangika mphamvu ya phula konkire, kuchititsa ming'alu. Basalt geogrid pakugwiritsa ntchito phula pamwamba wosanjikiza, kusintha pamwamba wosanjikiza wa yopingasa makokedwe mphamvu, kotero kuti kumakoka mphamvu ya phula konkire bwino kwambiri, akhoza kukana lalikulu kumakokedwe kupsyinjika popanda kuwonongeka. Kuonjezera apo, ngakhale chifukwa cha dera la ming'alu, mu ming'alu yomwe imachitika kupsinjika maganizo, ndi kusamutsidwa kwa basalt geogrid ndi kutha, ming'alu sidzakhala ming'alu.
Kuchedwetsa kuchepetsa ming'alu chonyezimira: mu phula ndi basalt geogrid wosanjikiza lathyathyathya, ziletsa kukameta ubweya kapena kukanika kupanikizika chifukwa cha kuchuluka kwa magalimoto, kumasula kupsyinjika, monga asphalt konkire kumangiriza zipangizo zolimbikitsira, kukwaniritsa cholinga kuchedwetsa kuchepetsa ming'alu.

3.Kugwiritsa ntchito geogrid yokhala ndi ulusi woyambira
Geogrid pakugwiritsa ntchito mfundo zazikuluzikulu za mphamvu, kukana misozi, ndi kuphatikiza kwa dothi, kulimba ndi chuma chake. Pakadali pano, geogrid yakhala ikugwiritsidwa ntchito pamisewu yayikulu, njanji yanjanji, mpanda wa dothi, kukweza kotsetsereka kwa banki, kuthandizira ndi kusunga mawonekedwe, kukonza kusanjikiza kwamiyala, kukonza njira yopititsira patsogolo komanso kupewa ndi kuwongolera ming'alu. Makamaka kugwiritsa ntchito geogrid pakuwongola njira komanso kupewa ming'alu yowonekera. Reflection crack ndi msinkhu wa udzu wamsewu chifukwa cha kusintha kwa kutentha kapena katundu wonyamula katundu wochuluka kwambiri ndi kutulutsa ming'alu, ndipo kupyolera mu interlayer stress propagation kupita pamwamba pa msewu, kutulutsa kayendedwe koyima kapena kopingasa pakati pa zigawo ndi kupanga msewu wosweka. Kugwiritsa ntchito geogrid yogwira ntchito kwambiri kumatha kupititsa patsogolo mphamvu yakumeta ubweya wamkati ndikupindika kwa kutopa kwa msewu, kusokoneza kupsinjika, motero kupewetsa ming'alu yapamsewu, ndikuchepetsa kwambiri mtengo wokonza msewu. Kuphulika kwa reflection ndi chodabwitsa chomwe chimapezeka pamiyala ya asphalt. Kwa ming'alu yonyezimira mumsewu, kuyala gawo la geotextile pakati pa phula ndi pansi kungathe kuthetsa kapena kuchepetsa mbadwo wa ming'alu yowonongeka pamtunda, motero kumawonjezera moyo wautumiki wa msewu. Koma phula kutsanulira kutentha kwa 160 ℃, chifukwa geotextile kapena polima geogrid khola, mapindikidwe, kufewetsa, kuti ntchito yake yafupika kwambiri. Kugwiritsidwa ntchito mumsewu wa phula geogrid ndi bwino kugwiritsa ntchito basalt CHIKWANGWANI geogrid, chifukwa basalt CHIKWANGWANI geogrid ali wabwino kutentha kukana, ndi mphamvu mkulu, modulus mkulu, otsika elongation, otsika coefficient cha kukulitsa matenthedwe ndi makhalidwe ena.
