Geogrid inoshandisa yakakwirira-simba repolyester faibha kana polypropylene faibha seyakagadzirwa, uye inotora warp knitting yakatarisana chimiro.Irwo shinda uye shinda mujira hadzina kukotama, uye mharadzano inosungwa nepamusoro-simba fiber filament kuti iite chisungo chakasimba, ichipa kutamba kwakazara kune yayo michina.Unoziva here kunaka kwayo kuneta kwayo crack resistance?
Mhedzisiro huru yeasphalt yakafukidzwa pane yekare simende kongiri pavement ndeyekuvandudza basa rekushandisa repavhu, asi haibatsiri zvakanyanya pakubereka mhedzisiro.Iyo kongiri yakaoma yakarongwa pasi pekafukidziro ichiri kuita basa rinokosha mukubereka.Iyo asphalt yakafukidzwa pane yekare asphalt kongiri pavement yakasiyana.Iyo asphalt yakafukidzirwa ichatakura mutoro pamwe chete neyekare asphalt kongiri pavement.Naizvozvo, asphalt yakafukidzwa pane asphalt kongiri pavement haingoratidzi kutsemuka, asiwo kuneta kutsemuka nekuda kwekureba kwekuita kwemutoro.Ngationgororei kushushikana kweasphalt pamusoro peiyo yekare asphalt kongiri pavement: nekuti iyo asphalt yakafukidzwa inofamba inochinjika ine hunhu hwakafanana neiyo asphalt yakafukidzwa, iyo nzira yemugwagwa ichatsauka kana ichiiswa pamutoro.Iyo asphalt yakavharika yakananga kubata vhiri iri pasi pekumanikidzwa, uye iyo nzvimbo iri pasi pekunetsekana munzvimbo iri mhiri kwegumbo rekutakura margin.Nemhaka yokuti simba rezvinhu zvezvikamu zviviri zvekumanikidzika zvakasiyana uye zviri pedyo kune mumwe nemumwe, kusanganiswa kwenzvimbo mbiri dzekutambudzika, kureva, kushanduka kamwe kamwe kwesimba, zviri nyore kukuvara.Pasi pemugumisiro wemutoro wenguva refu, kuneta kuputika kunoitika.
Mune asphalt yakafukidzwa, iyo geotextile inogona kusunungura iyo iri pamusoro compressive kushushikana uye tensile kushushikana, uye kugadzira buffer zone pakati penzvimbo mbiri dzekushushikana.Pano, kushushikana kunoshanduka zvishoma nezvishoma pane kamwe kamwe, kuderedza kukuvadzwa kweasphalt overlay kunokonzerwa nekushanduka kwekushungurudzika kwakangoerekana kwaitika.Iyo yakaderera kurebesa kwegirazi fiber geogrid inoderedza kutsauka kwepavhu uye inova nechokwadi chekuti nzira yacho haizotamburi nekushanduka kwekuchinja.
Unidirectional geogrid inoburitswa mumapepa matete nepolymer (polypropylene PP kana polyethylene HDPE), yobva yaroverwa mumambure akajairwa, yozotambanudzwa kureba.Mukuita uku, iyo polymer iri mumutsara mamiriro, ichigadzira akareba oval network chimiro nekugovera kwakafanana uye yakakwirira node simba.
Iyo unidirectional grid imhando yepamusoro-yakasimba geosynthetics, iyo inogona kukamurwa kuita unidirectional polypropylene grid uye unidirectional polyethylene grid.
Uniaxial tensile geogrid imhando yepamusoro-yakasimba geotextile ine yakakwira molecular polymer seyakanyanya mbishi zvinhu, inowedzerwa nemamwe anti ultraviolet uye anti-kuchembera ejenti.Mushure mekutambanudza unidirectional, iwo ekutanga akagoverwa cheni mamorekuru anodzoserwa kune mutsara mamiriro, uye obva awedzerwa mundiro yakatetepa, ichikanganisa yakajairika mesh, yozotambanudzwa kureba.Material Science.
Mukuita uku, iyo polymer inotungamirwa neiyo linear state, ichigadzira refu elliptical network chimiro nekugovera kwakafanana uye yakakwirira node simba.Ichi chimiro chine yakanyanya kusimba simba uye tensile modulus.Kusimba kwesimba ndeye 100-200Mpa, padyo nechiyero cheyakaderera kabhoni simbi, iri nani pane yechinyakare kana iripo yekusimbisa zvinhu.
Kunyanya, chigadzirwa ichi chine yekupedzisira-yepamusoro yekutanga nhanho yepasirese (kurebesa kwe2% - 5%) kusimba kwesimba uye kusimba modulus.Inopa hurongwa hwakanaka hwekuzvipira kwevhu uye kupararira.Ichi chigadzirwa chine simba rakanyanya kusimba (> 150Mpa) uye rinoshanda kune ivhu rakasiyana.Imhando yekusimbisa zvinhu zvinoshandiswa zvakanyanya pari zvino.Hunhu hwayo hukuru ndeyekusimba kwesimba, kuita kwakanaka kunofamba, kuvaka kuri nyore uye mutengo wakaderera.
