I-1, unyango lokufakwa kwe-asphalt kumphezulu we-adhesive enoxinzelelo lwe-geogrid
Umphezulu we-geogrid ufakwe kwi-self-adhesive pressure-sensitive adhesive ukulawula i-geogrid.I-asphalt efakwe kwi-self-adhesive self-adhesive pressure-sensitive adhesive kumphezulu we-geogrid yeyona nto iphambili ye-geosynthetic material ye-geogrid.Xa kuthelekiswa nezinye i-geosynthetics, i-HDPE geomembrane ibonisa ngokupheleleyo ukunyaniseka kwayo kunye nokusebenza kwayo.I-Geogrid isoloko isetyenziswa njengezinto eziqiniswayo zesakhiwo somhlaba esomeleziweyo okanye izinto eziqiniswayo zomenzi we-aluminium alloy geotextile.
I-Geogrid yahlulwe yangamacandelo amane: i-geogrid yeplastiki, i-geogrid yensimbi-yeplastiki, i-glass fibre geogrid kunye ne-glass fiber polyester geogrid.I-geogrid yePlastiki sisixhobo sothungelwano sepolymer esixande ngokupheleleyo okanye esibuxande esenziwe kukucheba okuqhubekayo.Ngokuhambelana nolwalathiso lwe-extrusion ngexesha lenkqubo yokukopisha, inokwahlulwa ibe ziindidi ezimbini: indlela enye yokucheba kunye ne-extrusion yeendlela ezimbini.
Kukugqobhoza imingxunya kwezinye iipleyiti zepolymer ezichatshazelwe yi-extrusion, kwaye emva koko utyhale phambili ukolulwa kwecala phantsi kwesiseko sokupholisa.Xa i-crack ye-geotextile ifikelela kwi-10% yobungakanani bomqulu, kufuneka sisebenze inxalenye eyonakalisiweyo, kwaye emva koko sidibanise amaza amabini omhlaba ngokusondeleyo.Ukongezelela, ukuba i-gap kwi-slope surface ifikelela kwi-10% ye-roll size, i-geotextile roll kufuneka isuswe kwaye ithathelwe indawo entsha.Izinto zokugquma ezisetyenziswe ngumvelisi we-geogrid geomembrane kwinkqubo yokunyanga emva kokunyanga ijoliswe kumenzi wezinto ezidibeneyo ze-asphalt.
Ifiber nganye ihlanganiswe ngokupheleleyo kwaye ihambelana ngokupheleleyo ne-asphalt, ukwenzela ukuba kuqinisekiswe ukuba i-glass fiber geogrid kwi-asphalt layer ayiyi kunqunyulwa kwi-asphalt composite material, kodwa idibaniswe ngokuqinileyo.I-geogrid iya kubekwa kumaleko asezantsi athambileyo ngokobungakanani obulungisiweyo.Isigcwalisi sekhosi yesiseko esiphezulu asiyi kugqobhoza inkunkuma ye-geogrid.Xa i-geogrid ibekwe, isantya somoya siphezulu kakhulu ukuwela i-axis esembindini yongqameko.I-Geogrid ibekwe ngobude.Indawo yokubeka iya kuqiniswa ukunqanda ukushwabana, ukujijeka okanye ukugoba.
I-geogrid idityaniswe ngokuthe tye ngendlela yokugqithisa, kwaye ubungakanani bokukhwela abukho ngaphezu kwe-20cm.Emva kokuba i-geogrid ibekwe, ukufakwa kwe-manual ye-fipper layer filler kuya kugqitywa ngokukhawuleza ukukhusela ukukhanya kwelanga unyaka wonke.Emva koko uqhube uthutho lwemathiriyeli yoomatshini, ukulinganisa kunye nokuqengqeleka.I-mechanical paving and rolling yenziwa ukusuka kumacala omabini ukuya kumacala omabini, kwaye ukuqengqeleka kuqhutyelwa kumacala omabini ukuya kumacala omabini, kwaye ukunyanzeliswa kugcinwa ukufezekisa ukupheliswa okusemgangathweni.
I-2, i-Geogrid inamandla okuqina entsimbi ethambileyo
I-geogrid iphinda ihlengahlengise iimolekyuli ze-hydrocarbon ezinde zepolymer kumgca othe ngqo ecaleni kwendlela eyolulayo ngenkqubo yobuchwepheshe eyodwa.Amandla okubopha phakathi kwamatyathanga e-molekyuli aqiniswa kakhulu, ngoko ke anamandla aphezulu kunye nobude obuphantsi.Ngokomzekelo, ukuqina kwamandla kumaxesha angama-5-10 aphezulu kunalo ngaphambi kokwelula, kwaye i-elongation i-10% kuphela - i-15% ephezulu kunoko ngaphambi kokwelula.Amandla okudibanisa amaqhekeza kwigridi ayanda, kwaye i-friction coefficient iyanda kakhulu.Kunokuthiwa phakathi kwee-geosynthetics ezininzi, amandla okuqina e-geogrid ngawona aphakamileyo phantsi koxinzelelo olufanayo, kwaye amandla ayo okuqina asondele kwintsimbi ethambileyo.Ukongeza kumandla ayo okuqina okuqina, i-geogrid ikwanayo nokuqina okuhle, kuba imathiriyeli ye-geogrid yenziwe nge-polyethylene ephezulu okanye iplastiki ye-polypropylene njengeyona nto iphambili ekrwada, kwaye iqulethe izongezo ezichasene nokwaluphala ezifana ne-UV kunye ne-carbon emnyama, enokuthi ukuthintela ukukhukuliseka kwezinyibilikisi eziphilayo ezifana ne-asidi, i-alkali, ityuwa, utywala, i-petroli kunye ne-UV.Ngokutsho kwedatha efanelekileyo, ubomi benkonzo ye-geogrid eveliswe ngabavelisi be-geogrid inokufikelela kwiminyaka eyi-120 phantsi kweemeko eziqhelekileyo zokushisa kunye noyilo lomthwalo ovumelekileyo.Kakade ke, isizathu sokuba i-geogrids isetyenziswe ngokubanzi kukuba i-geogrids echazwe ngezantsi ineempawu ezibalaseleyo.Kwiprojekthi yokuhombisa ithambeka, i-geocell yeplastiki yomenzi we-geogrid, emva kokuba i-geocell yandisiwe kwaye yavulwa, inikezela ngekhekheba le-honey-dimensional geocell, kwaye igcwalise i-geocell ngomhlaba kunye nelitye okanye izixhobo zekhonkrithi ukwenza isakhiwo esinokuthintela olomeleleyo olusecaleni kwaye ukuqina okukhulu ukwenza umphumo uzinzo kwithambeka.Isenokulima ezinye izityalo, okanye amatyholo amancinci kunye nezinye izityalo kwi-geogrid, ukwenza igridi yefiber yeglasi echaseneyo yinto ephambili ye-geosynthetic, enomsebenzi ofanayo kunye nesiphumo xa kuthelekiswa nezinye izinto ze-geosynthetic.Igridi yefiber yeglasi isoloko isetyenziswa njengokuqiniswa kwezakhiwo zomhlaba eziqinisiweyo okanye izinto ezidibeneyo
