I-Geogrid isebenzisa i-polyester fiber enamandla amakhulu noma i-polypropylene fiber njengempahla eluhlaza, futhi yamukela isakhiwo esimake ukunitha se-warp.Izintambo ezinqamula kanye ne-weft endwangu azigobi, futhi ukuphambana mgwaqo kuboshwe ngefilament enamandla amakhulu ukuze kwakhiwe ihlangano eqinile, enikeza ukudlala okugcwele ezicini zayo zemishini.Uyazi ukuthi kuhle kangakanani ukumelana kwayo nokukhathala?
Umthelela oyinhloko wokumbondela kwe-asphalt endaweni egandaywe ngosimende endala uwukuthuthukisa umsebenzi wokusebenza we-pavement, kodwa awufaki isandla kakhulu emthelela wokuthwala.Indawo egandaywe ngokhonkolo eqinile ngaphansi kwembondela isadlala indima ebalulekile ekuthwaleni.I-asphalt embozwe endaweni egandaywe kakhonkolo endala ye-asphalt ihlukile.Imbondela ye-asphalt izothwala umthwalo kanye nendawo egandaywe kakhonkolo endala.Ngakho-ke, ukumbozwa kwe-asphalt emgwaqeni okhonkolo we-asphalt ngeke kuveze imifantu yokubonisa kuphela, kodwa futhi nokuqhekeka kokukhathala ngenxa yomphumela wesikhathi eside womthwalo.Ake sihlaziye ukucindezelwa kwembondela ye-asphalt endaweni egandayiwe kakhonkolo ye-asphalt endala: ngenxa yokuthi i-asphalt imbondela iwumgwaqo oguquguqukayo onemvelo efanayo nembondela ye-asphalt, indawo yomgwaqo izophambuka lapho ingaphansi komphumela womthwalo.Imbondela ye-asphalt ethinta ngqo isondo ingaphansi kwengcindezi, futhi indawo engaphezulu ingaphansi kokushuba endaweni ngale kwemajini yomthwalo wesondo.Ngenxa yokuthi izakhiwo zamandla zezindawo ezimbili zokucindezeleka zihlukile futhi zisondelene komunye nomunye, ukuhlangana kwezindawo ezimbili zokucindezeleka, okungukuthi, ukuguqulwa okungazelelwe kwamandla, kulula ukulimaza.Ngaphansi komphumela womthwalo wesikhathi eside, ukuqhekeka kokukhathala kwenzeka.
Embombeni ye-asphalt, i-geotextile ingakhulula ingcindezi ecindezelayo engenhla kanye nengcindezi eqinile, futhi yakhe indawo ye-buffer phakathi kwezindawo ezimbili ezithwala ingcindezi.Lapha, ukucindezeleka kushintsha kancane kancane kunokuba kungazelelwe, kunciphisa umonakalo wokumbondela kwe-asphalt okubangelwa ukushintsha kokucindezeleka okungazelelwe.Ukwelulwa okuphansi kwe-fiber geogrid yengilazi kunciphisa ukuchezuka kwendlela egandayiwe futhi kuqinisekisa ukuthi indlela egandayiwe ngeke ihlupheke ngenxa yokuguquguquka.
I-geogrid ye-unidirectional ikhishwa ibe amashidi azacile nge-polymer (i-polypropylene PP noma i-polyethylene HDPE), bese igxotshwa enethini evamile, bese yelulelwa ngobude.Kule nqubo, i-polymer isesimweni somugqa, yenza uhlaka olude lwenethiwekhi ye-oval enokusabalalisa okufanayo kanye namandla aphezulu e-node.
Igridi ye-unidirectional iwuhlobo lwe-geosynthetics yamandla aphezulu, engahlukaniswa ibe igridi ye-polypropylene engaqondile kanye negridi ye-polyethylene engaqondile.
I-Uniaxial tensile geogrid iwuhlobo lwe-geotextile enamandla amakhulu ene-polymer yamangqamuzana aphezulu njengempahla eluhlaza eyinhloko, engezwe ngama-anti ultraviolet nama-anti-aging agents.Ngemva kokwelula okukodwa, ama-molecule asekuqaleni asabalalisiwe aqondiswa kabusha ukuze abe esimweni somugqa, bese ekhishwa abe yipuleti elincanyana, elithinta i-mesh evamile, bese enwetshwa ngobude.Isayensi Yezinto Ezibalulekile.
Kule nqubo, i-polymer iqondiswa isimo somugqa, yakha isakhiwo senethiwekhi ende ye-elliptical ngokusabalalisa okufanayo kanye namandla aphezulu e-node.Lesi sakhiwo sinamandla aphezulu kakhulu okudonsa kanye ne-tensile modulus.Amandla aqinile yi-100-200Mpa, eduze nezinga lensimbi ephansi ye-carbon, engcono kakhulu kunezinto zokuqinisa zendabuko noma ezikhona.
Ikakhulukazi, lo mkhiqizo unezinga eliphezulu kakhulu lasekuqaleni lamazwe ngamazwe (ubude obungu-2% - 5%) amandla okuqina kanye ne-tensile modulus.Inikeza uhlelo olufanele lokuzibophezela kwenhlabathi nokusabalalisa.Lo mkhiqizo unamandla okudonsa kanzima (>150Mpa) futhi usebenza enhlabathini ehlukahlukene.Kuwuhlobo lwezinto eziqinisayo ezisetshenziswa kabanzi njengamanje.Izici zayo eziyinhloko amandla aqinile, ukusebenza kahle kwe-creep, ukwakhiwa okulula kanye nenani eliphansi.
