Geogrid yog cov khoom siv geosynthetic loj, uas muaj qhov ua tau zoo thiab ua tau zoo piv rau lwm yamgeosyntheticcov ntaub ntawv. Feem ntau siv los ua kev txhawb nqa rau cov khoom siv hauv av los yog cov khoom sib xyaw. Geogrids tau muab faib ua plaub pawg: yas geogrids, steel yas geogrids, iav fiber ntau geogrids, thiab polyester warp knitted polyester geogrids. Grille yog ib daim phiaj ob-seem lossis daim phiaj peb-dimensional nrog ib qhov siab uas tsim los ntawm cov thermoplastic lossis molded siab polymer cov ntaub ntawv xws li polypropylene thiab polyvinyl chloride. Thaum siv hauv engineering engineering, nws yog hu ua geogrid.
Vim tsis muaj zog thiab deformability, cement qhob pavement undergoes tsis sib haum nyob rau hauv lub zos, uas hloov lub xeev kev nyuaj siab thiab kev khiav hauj lwm tej yam kev mob, tsub kom lub internal kev nyuaj siab ntawm pob zeb blocks, ua rau puas pob zeb blocks thiab txo lub lifespan ntawm cov pob zeb pavement.
Yuav daws qhov teeb meem no li cas thiab tiv thaiv kev puas tsuaj? Cov yam ntxwv zoo heev ntawmgeogridsthiab kev kho qhov chaw tshwj xeeb muaj peb qhov teebmeem. Ua ntej, tso geogrids txhim kho tag nrho lub zog ntawm lub hauv paus ntawm cov txiv qaub av saum npoo ntawm lub hauv paus txheej. Tom qab ntawd tshuaj tsuag txheej ntawm hydrothermal asphalt hnyav roj (roj los yog binder txheej), uas tuaj yeem tiv thaiv kev yaig ntawm cov dej nag cov txiv qaub av ntawm qhov chaw ntawm lub hauv paus txheej txheej, yog li ncua lub neej ntawm txiv qaub av hauv paus. Thib ob,geogridstuaj yeem tiv thaiv kev tawg ntawm cov cement pavement tshwm sim los ntawm qhov kub thiab txias shrinkage vim qaug zog ntawm lub hauv paus tshauv thiab av.
Geogrid reinforced pob zeb tuaj yeem ua tus tswv cuab ntxiv rau nws cov pob zeb ua kom muaj zog, thiab kev nyuaj siab ntawm txoj kev tuaj yeem sib kis tau zoo los tiv thaiv kev cuam tshuam ntawm kev cuam tshuam, yog li txuas ntxiv lub neej kev pab cuam ntawm cov pob zeb ua pa.
