Iindaba

I-Geogrid isebenzisa ifayibha ye-polyester ephezulu okanye i-polypropylene ifayibha njengento eluhlaza, kwaye yamkele i-warp knitting oriented structure.Imisonto ye-warp kunye ne-weft kwilaphu ayinakugoba, kwaye i-intersection iboshwe nge-fiber filament ephezulu yamandla ukuze yenze ukudibanisa okuqinileyo, ukunika umdlalo opheleleyo kwiimpawu zayo zomatshini.Ngaba uyazi ukuba kuhle kangakanani ukumelana kwayo nokudinwa?
Impembelelo ephambili ye-asphalt yokugqithisa kwi-pavement yekhonkrithi endala kukuphucula umsebenzi wokusetyenziswa kwe-pavement, kodwa ayifaki negalelo elikhulu kwimpembelelo yokuthwala.Indlela eqinileyo yesamente egayiweyo phantsi kwesigqubuthelo isadlala indima ebalulekileyo ekuthwaleni.Ukwaleka kwe-asphalt kwipavumente endala yekhonkrithi yahlukile.Isigqubuthelo se-asphalt siya kuthwala umthwalo kunye nepavumente endala yekhonkrithi.Ngoko ke, ukugqithiswa kwe-asphalt kwi-pavement yekhonkrithi ye-asphalt ayiyi kubonisa kuphela iintanda ezibonakalisiweyo, kodwa kunye nokuqhekeka kokukhathala ngenxa yempembelelo yexesha elide lomthwalo.Makhe sihlalutye uxinzelelo lwe-asphalt yokwaleka kwi-asphalt yekhonkrithi endala: ngenxa yokuba i-asphalt yokugqithisa i-flexible pavement kunye nendalo efanayo kunye nokugqithisa kwe-asphalt, umgangatho wendlela uya kuphambuka xa uphantsi komthwalo womthwalo.I-asphalt yokwaleka ngokuthe ngqo kwivili iphantsi koxinzelelo, kwaye umphezulu uphantsi koxinzelelo kwindawo engaphaya komda womthwalo wevili.Ngenxa yokuba iipropathi zamandla eendawo ezimbini zoxinzelelo zihlukile kwaye zisondelelene, ukuhlangana kweendawo ezimbini zoxinzelelo, oko kukuthi, ukuguqulwa ngokukhawuleza kwamandla, kulula ukonakala.Ngaphantsi komphumo womthwalo wexesha elide, ukuchithwa kokukhathala kwenzeka.
Kumagqubu e-asphalt, i-geotextile inokukhulula olu xinzelelo lungentla kunye noxinzelelo lwe-tensile, kwaye yenze indawo ye-buffer phakathi kweendawo ezimbini ezithwele uxinzelelo.Apha, uxinzelelo lutshintsha ngokuthe ngcembe kunokuba ngokukhawuleza, ukunciphisa umonakalo kwi-asphalt overlay obangelwa utshintsho ngokukhawuleza loxinzelelo.Ubude obuphantsi be-glass fibre geogrid kunciphisa ukuphambuka kwendlela yokuhamba kwaye iqinisekisa ukuba i-pavement ayiyi kubandezeleka ngenxa yokuguqulwa kwenguqu.
I-geogrid ye-unidirectional ikhutshelwa kumaphepha amancinci nge-polymer (i-polypropylene PP okanye i-polyethylene HDPE), kwaye ibethelwe kwi-mesh eqhelekileyo, kwaye yolulwe ixesha elide.Kule nkqubo, i-polymer ikwimeko yomgca, yenza ulwakhiwo olude lwe-oval network kunye nokusabalalisa okufanayo kunye namandla aphezulu e-node.
Igridi ye-unidirectional luhlobo lwe-geosynthetics ephezulu, enokuthi ihlulwe ibe yigridi ye-polypropylene ye-unidirectional kunye negridi ye-polyethylene unidirectional.
I-Uniaxial tensile geogrid luhlobo lwe-geotextile yokuqina okuphezulu kunye ne-polymer ephezulu yemolekyuli njengeyona nto iphambili yemathiriyeli ekrwada, eyongezwe kunye ne-anti ultraviolet kunye ne-anti-aging agents.Emva kokwelula okungafaniyo, iimolekyuli zokuqala ezisasaziweyo ziphinde zilungelelaniswe kwimeko elungeleleneyo, kwaye emva koko zikhutshelwe kwipleyiti encinci, ichaphazele i-mesh eqhelekileyo, kwaye yolulwe ixesha elide.Inzululwazi yezinto eziphathekayo.
Kule nkqubo, i-polymer ikhokelwa yi-linear state, yenza i-elliptical network structure kunye nokusabalalisa okufanayo kunye namandla aphezulu e-node.Esi sakhiwo sinamandla aphezulu kakhulu kunye nemodyuli yokuqina.Amandla e-tensile yi-100-200Mpa, kufuphi nenqanaba lentsimbi ye-carbon ephantsi, engcono kakhulu kunezinto eziqhelekileyo okanye ezikhoyo zokuqinisa.
Ngokukodwa, le mveliso inenqanaba eliphezulu kakhulu lakwamanye amazwe (i-elongation ye-2% - 5%) yamandla okuqina kunye nemodyuli yokuqina.Ibonelela ngenkqubo efanelekileyo yokuzinikela komhlaba kunye nokusabalalisa.Le mveliso inamandla okuqina aphezulu (>150Mpa) kwaye iyasebenza kwimihlaba eyahlukeneyo.Luhlobo lwemathiriyeli yokuqinisa esetyenziswa ngokubanzi ngoku.Iimpawu zayo eziphambili zinamandla aphezulu, ukusebenza kakuhle kwe-creep, ukwakhiwa okufanelekileyo kunye nexabiso eliphantsi.
