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 ikwanokuqina okuhle, kuba imathiriyeli ye-geogrid yenziwe nge-polyethylene ephezulu okanye iplastiki ye-polypropylene njengeyona nto iphambili ekrwada, kwaye iqulethe izongezo ezichasene nokuguga njenge-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 i-honeycomb ye-honey-dimensional geocell, kwaye igcwalise i-geocell ngomhlaba kunye namatye okanye izixhobo zekhonkrithi ukwenza isakhiwo esinezithintelo ezinamandla ezisecaleni kunye. ukuqina okukhulu ukwenza umphumo uzinzo kwithambeka. Isenokulima uhlaza oluthile, 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
