Kugwiritsa ntchito singano - geotextiles

Geotextile, yomwe imadziwikanso kuti geofabric, imapangidwa ndi ulusi wopangidwa ndi kusowa kapena kuluka zinthu zomwe zimatha kulowa m'madzi. Geotextile ndi chimodzi mwa zinthu zatsopano geosynthetic zipangizo, chomalizidwa nsalu, lonse m'lifupi ndi 4-6 mamita, kutalika ndi 50-100 metres. ethylene CHIKWANGWANI ndi zina kusowa nonwoven geotextiles malinga ndi zopangira.Makhalidwe. wa geosynthetic ndi permeability madzi, kukana dzimbiri, kukana kuvala, kulimba kwamphamvu kwambiri, kukana kukalamba ndi zina zotero. Geotextile ndi mtundu wa zinthu za geotechnical zomwe zimagwiritsidwa ntchito kwambiri pomanga misewu, madamu, ma tunnel, ma DAMS ndi zina zotero. Ntchito zake zazikulu ndi kulekanitsa, kusefera, ngalande, kukhazikika ndi kulimbikitsa. Chifukwa chakugwiritsa ntchito kwambiri komanso kufunikira kwake, mphamvu zolimba, kusweka mphamvu, permeability ndi kulemera kwa nsalu ndi zinthu zina ndizofunikira kwambiri. Singano ya nyenyezi ya singano ya Hengxiang ndiyoyenera kwambiri kupanga geotextile yamphamvu kwambiri, makamaka popanga ulusi wochita kupanga komanso nsalu zadongo zozungulira ndizodziwikiratu. Singano yooneka ngati nyenyezi ya nsonga za mbedza za mbali zinayi imathandizira kuloŵerera kwakukulu ndi kuchepetsa kuwonongeka kwa ulusi. Pali mitundu yambiri ya ulusi womwe umagwiritsidwa ntchito popanga ma geotextiles, kutengera momwe amagwirira ntchito. Zodziwika bwino ndi polyester, polypropylene, nayiloni. Kukhuthala kwa ulusi nthawi zambiri kumakhala pakati pa 4 ndi 10, pomwe zinthu zina zimagwiritsa ntchito ulusi wokhuthala. Kuzama kofunikira nthawi zambiri kumakhala 10 mpaka 12mm, ndipo kachulukidwe kofunikira nthawi zambiri amakhala 100 mpaka 400 singano pa C lalikulu mita. Nsalu yadongo yopota nthawi zambiri imafunikira makina osokera othamanga kwambiri omwe ali ndi liwiro la minga 2000 mpaka 3000 pa mphindi imodzi, ndipo kachulukidwe ka nsonga ndi kocheperako. Kawirikawiri makina osokera kwambiri ndi minga 100 mpaka 300 pa C lalikulu mamita, ndipo kuya kwake kofunikira ndi 10 mpaka 12mm.
