I-1, Ukwelashwa kwe-Asphalt impregnation ebusweni be-adhesive ebucayi yokucindezela ye-geogrid
Indawo ye-geogrid ifakwe ngokunamathelayo okuzwela ukucindezela okuzinamathelayo ukuze kulawulwe i-geogrid. I-asphalt egxilile enamathelayo ezwela ukucindezela ebusweni be-geogrid iyinto eyinhloko ye-geosynthetic ye-geogrid. Uma kuqhathaniswa namanye ama-geosynthetics, i-HDPE geomembrane ibonisa ngokugcwele ubuqiniso bayo nokusebenza kwayo. I-Geogrid ivamise ukusetshenziswa njengezinto eziqinisayo zesakhiwo somhlaba esiqinisiwe noma izinto zokuqinisa zomkhiqizi we-aluminium alloy geotextile.

I-Geogrid ihlukaniswe izigaba ezine: i-plastic geogrid, i-steel-plastic geogrid, i-glass fibre geogrid kanye ne-glass fiber polyester geogrid. I-geogrid yepulasitiki iyinethiwekhi ye-polymer engunxande ngokuphelele noma engunxande eyakhiwe ukugunda okuqhubekayo. Ngokusho kokuvumelana kwesiqondiso se-extrusion phakathi nenqubo yokukopisha, ingahlukaniswa ngezinhlobo ezimbili: i-shear yendlela eyodwa kanye ne-extrusion yezindlela ezimbili.
Iwukubhoboza izimbobo kwamanye amapuleti e-polymer athintwe i-extrusion, bese uphushela phambili ukwelula okuqondile ngaphansi kwesisekelo sokupholisa. Lapho ukuqhekeka kwe-geotextile kufika ku-10% wosayizi we-roll, sidinga ukusebenzisa ingxenye eyonakele, bese sixhuma amagagasi omhlaba eduze. Ukwengeza, uma igebe endaweni yemithambeka lifinyelela ku-10% wesayizi we-roll, i-geotextile roll kufanele isuswe futhi esikhundleni sayo kufakwe umqulu omusha. Izinto zokumboza ezisetshenziswa umkhiqizi we-geogrid geomembrane enqubweni yokwelashwa ngemuva kokwelashwa ziqondiswe kumkhiqizi wezinto ezihlanganisiwe ze-asphalt.
I-fiber ngayinye ihlanganiswe ngokuphelele futhi ihambisana ngokugcwele ne-asphalt, ukuze kuqinisekiswe ukuthi i-fiber geogrid yengilazi engqimbeni ye-asphalt ngeke inqunywe ezintweni ezihlanganisiwe ze-asphalt, kodwa ihlanganiswe ngokuqinile. I-geogrid izobekwa phezu kongqimba oluphansi oluthambile ngokuya ngosayizi wempango olungisiwe. Isigcwalisi senkambo yesisekelo esiphezulu ngeke sibhoboze imfucumfucu ye-geogrid. Lapho i-geogrid ibekwa, isivinini somoya siphezulu kakhulu ukuwela i-axis emaphakathi yothango. I-Geogrid ibekwe ngobude. Indawo yokubeka kufanele iqiniswe ukuvimbela ukushwabana, ukusonteka noma ukugoba.
I-geogrid ixhunywe ngokuvundlile ngendlela egqagqene, futhi usayizi wokugibela awukho ngaphezu kuka-20cm. Ngemva kokubekwa kwe-geogrid, ukufakwa kwemanuwali kwesigcwalisi sengqimba engenhla kuzoqedwa ngokushesha ukuze kuvinjelwe ukuchayeka elangeni unyaka wonke. Bese uqhuba izinto zokuhamba ngomshini, ukukala nokugingqa. I-mechanical paving and rolling yenziwa kusukela ezinhlangothini zombili kuya ezinhlangothini zombili, futhi ukugoqa kwenziwa kusuka ezinhlangothini zombili kuya ezinhlangothini zombili, futhi ukubumbana kugcinwa ukuze kufinyelele ukuqedwa okujwayelekile.
I-2, i-Geogrid inamandla aqinile ensimbi emnene
I-geogrid ihlela kabusha ama-molecule eketango elide le-hydrocarbon ye-polymer ngomugqa oqondile eduze nendawo enwebekayo ngenqubo yobuchwepheshe eyingqayizivele. Amandla okubopha phakathi kwamaketanga e-molecular aqiniswa kakhulu, ngakho-ke anamandla aphezulu okudonsa kanye nobude obuphansi. Isibonelo, amandla e-tensile aphindwe izikhathi ezingu-5-10 kunalokho ngaphambi kokwelula, futhi ubude bungu-10% - 15% kuphela ngaphezu kwalokho ngaphambi kokwelula. Amandla ahlanganayo ezinhlayiya kugridi ayanda, futhi i-coefficient ye-friction ikhula kakhulu. Kungashiwo ukuthi phakathi kwama-geosynthetics amaningi, amandla aqinile we-geogrid aphakeme kakhulu ngaphansi kohlobo olufanayo, futhi amandla ayo aqinile asondelene nalawo ensimbi ethambile. Ngaphezu kokuqina kwayo okuqinile, i-geogrid iphinde ibe nokuqina okuhle, ngoba impahla ye-geogrid yenziwe nge-polyethylene ephakeme kakhulu noma ipulasitiki ye-polypropylene njengento eluhlaza eyinhloko, futhi iqukethe izithasiselo zokulwa nokuguga ezifana ne-UV kanye ne-carbon black, engakwazi. vimbela ukuguguleka kwezincibilikisi eziphilayo njenge-asidi, i-alkali, usawoti, utshwala, uphethiloli kanye ne-UV. Ngokusho kwedatha efanelekile, impilo yesevisi ye-geogrid ekhiqizwe abakhiqizi be-geogrid ingafinyelela iminyaka engu-120 ngaphansi kwezimo ezijwayelekile zokushisa nokuklama umthwalo ovumelekile. Yebo, isizathu esenza ukuthi ama-geogrid asetshenziswe kabanzi ukuthi ama-geogrid achazwe ngezansi anezici ezinhle kakhulu. Kuphrojekthi yokuhlobisa umthambeka, i-geocell yepulasitiki yomkhiqizi we-geogrid, ngemva kokuba i-geocell inwetshiwe futhi ivuliwe, iveza ikhekheba lezinyosi elinezinhlangothi ezintathu ze-geocell, futhi igcwalisa i-geocell ngomhlaba namatshe noma izinto zikakhonkolo ukuze zakhe isakhiwo esinezithiyo ezinamandla ezingemuva futhi ukuqina okukhulu ukwenza umphumela wokuzinza emthambekeni. Ingase futhi ihlakulele ezinye izimila, noma izihlahlana ezincane nezinye izitshalo ku-geogrid, ukwakha igridi ye-glass fibre ephambene yinto eyinhloko ye-geosynthetic, esebenza ngokufana nomthelela uma kuqhathaniswa nezinye izinto ze-geosynthetic. Igridi yefiber yengilazi ivame ukusetshenziswa njengokuqinisa izakhiwo zenhlabathi eziqinisiwe noma izinto eziyinhlanganisela
