ʻO Geogrid wiliwili kila kila me ka hiki ke hoʻopaʻa ʻia no ke ala kaʻaahi kaʻaahi ma lalo o ka puʻu
Nā kikoʻī huahana
ʻO Fiberglass geogrid kahi mea geosynthetic maikaʻi loa i hoʻohana ʻia no ka hoʻoikaika ʻana i ke alanui, ka hoʻoikaika ʻana i ke alanui kahiko, ka hoʻoikaika ʻana i ke kumu alanui a me ke kumu lepo palupalu. ʻO Fiberglass geogrid kahi huahana semi-rigid i hana ʻia me ka ikaika kiʻekiʻe alkali-free fiberglass ma o ke kaʻina hana wili warp holomua honua a uhi ʻia e ka mālama ʻana. Loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka elongation haʻahaʻa ma nā ʻaoʻao warp a me ka weft, a loaʻa iā ia nā waiwai maikaʻi loa o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa, ke kūpaʻa ʻelemakule, ka pale ʻana i ka corrosion, a me nā mea ʻē aʻe. alanui kaʻaahi, pale slope dam, kahua mokulele, hoʻomalu one a me nā papahana ʻenekinia ʻē aʻe.
ʻO ka mea nui o ka fiberglass ʻo ia: silicon oxide, nā mea inorganic, ʻo kona mau kino kino a me nā waiwai kemika he paʻa loa, a he modulus kiʻekiʻe, ʻaʻahu kūpaʻa a me ke kūpaʻa anuanu maikaʻi loa, ʻaʻohe kolo lōʻihi; maikaʻi paʻa wela; mesh hale i hiki i ka aggregate embedded laka a me ka palena; e hoʻomaikaʻi i ka hiki ke amo i ka haawe o ka hui asphalt. No ka mea ua uhi ʻia ka ʻili me ka asphalt i hoʻololi ʻia, ʻelua mau waiwai hui, ʻo nā waiwai maikaʻi loa o ka fiberglass a me ka hoʻohālikelike ʻana me ka hui ʻana o ka asphalt, kahi e hoʻomaikaʻi ai i ke kūpaʻa abrasion a me ka pale ʻana o geogrid.
Nā hiʻohiʻona o nā huahana geogrid fiberglass
ʻO ka huahana he ikaika kiʻekiʻe, haʻahaʻa elongation, kiʻekiʻe wela kū'ē, kiʻekiʻe modulus, māmā kaumaha, maikaʻi toughness, corrosion kū'ē, ola lōʻihi, etc. Hiki ke hoʻohana nui ia i loko o ka kahiko sima pavement, airport runway mālama, embankment, muliwai kapa, ka pale ʻana i ka pali, ka mālama ʻana i ke ala a me ke alahaka a me nā ʻano ʻenekinia ʻē aʻe, hiki ke hāʻawi i ka hoʻonui ʻana i ka pavement, hoʻoikaika, pale i ka pavement rutting fatigue crack, wela a me ke anu hoʻonui ʻia a me ka noʻonoʻo. māwae lalo, a hiki Puka, hooloihi i ka lawelawe ola o ka papahele, kiʻekiʻe tensile ikaika haʻahaʻa elongation,ʻaʻohe lōʻihi-manawa kolo, maikai kino a me kemika paʻa, maikaʻi thermal paʻa, luhi pohā kū'ē, kiʻekiʻe wela rutting kū'ē, haʻahaʻa wela shrinkage pohā kū'ē. , ka emi ʻana o nā māwae noonoo.
ʻO ke kaʻina hana hana geogrid fiberglass
(1) ʻO ka mea mua, e hoʻopau pololei i ka laina slope o ke alanui, i mea e hōʻoia ai i ka laulā o ke alanui, ua hoʻonui ʻia kēlā me kēia ʻaoʻao e 0.5m, ka maloʻo ʻana o ka lepo substrate maikaʻi no ka pae ʻana ma hope o ka hoʻohana ʻana i ka 25T vibratory roller static pressure. ʻelua manawa, a laila 50T haʻalulu i ʻehā mau manawa, ka wahi ʻole me ka pae lima.
(2) Ka waiho ʻana i 0.3m mānoanoa (coarse) one, manual me ka mechanical leveling, 25T vibration roller static pressure ʻelua manawa.
(3) ka waiho ʻana o ka geogrid, ʻo ka geogrid e waiho ana i lalo ka ʻili he palahalaha, ʻoʻoleʻa, maʻamau pono e waiho palahalaha, pololei, ʻaʻohe uhi, ʻaʻohe curl, kink, ʻelua geogrid pili pono e lap 0.2m, a ma ka ʻaoʻao o ke alanui geogrid ʻāpana āpau i kēlā me kēia. 1m me No. 8 uea no ka interpolation pili, a i loko o ka waiho grids, kela 1.5-2m me U-nails i paa i ka lepo.
(4) ka papa mua o geogrid paved, hoomaka e hoopiha i ka lua o ka papa o 0.2m mānoanoa i (coarse) one, ke ala: kaʻa one i ka paena unloaded ma ka aoao o ke alanui, a laila, e hoʻohana i ka bulldozer e pana i mua. , ʻelua mau mika mua ma nā ʻaoʻao ʻelua o ke alanui ma hope o ka hoʻopiha ʻana i ka 0.1m, ʻo ka papa mua o ka geogrid i pelu ʻia a laila hoʻopiha ʻia me 0.1m i ke one (coarse), pāpā. ʻO nā ʻaoʻao ʻelua i ka waena o ka hoʻopiha a me ka holomua, pāpā i nā ʻano mīkini āpau i ka ʻole o kēia hiki ke hōʻoia i ka palahalaha o ka geogrid, me ka ʻole o nā pahu a me nā wrinkles, a ma hope o ka papa lua o ke one (coarse) palahalaha, ka pae. Pono e hana ʻia ke ana no ka pale ʻana i ka mānoanoa o ka hoʻopiha piha ʻana, a pono e hoʻohana ʻia ka roller vibratory 25T i ʻelua mau manawa ma hope o ka pololei o ka pae ʻana.
(5) ka papa ʻelua o ke ʻano hana geogrid me ka papa mua o ke ʻano like, a hoʻopiha hope i ka 0.3m i ke one (coarse), e hoʻopiha ana i ke ʻano like me ka papa mua, me ka 25T roller static pressure ʻelua mau manawa, no laila ka hoʻopau ʻia ka hoʻoikaika ʻana o ka substrate ma ke alanui.
