Kuyambira kumayambiriro kwa zaka za m'ma 1980, China yayamba kugwiritsa ntchito ndi kufufuza zinthu zopangidwa monga geotextiles.Kupyolera mukugwiritsa ntchito m'mapulojekiti ambiri, ubwino wa nkhaniyi ndi teknoloji ikudziwika kwambiri ndi gulu la engineering.Geosynthetics ili ndi ntchito monga kusefera, ngalande, kudzipatula, kulimbitsa, kupewa kutulutsa, ndi chitetezo.Pakati pawo, ntchito zolimbikitsira (makamaka mitundu yatsopano ya geosynthetics) zakhala zikugwiritsidwa ntchito kwambiri m'zaka zaposachedwa, ndipo magawo awo ogwiritsira ntchito akukulitsidwa pang'onopang'ono.Komabe, kugwiritsa ntchito ukadaulo uwu ku China sikunafalikirebe, ndipo pakali pano kuli pachiwonetsero, makamaka m'mapulojekiti akulu ndi apakatikati.Geogrid wopanga dongosolo
Zapezeka kuti pakadali pano, ma geogrids amagwiritsidwa ntchito makamaka mumisewu yayikulu, njanji, ndi ma projekiti ena, komanso amagwiritsidwa ntchito pang'onopang'ono popanga ma hydraulic engineering monga mizati yoletsa kusefukira kwa madzi, ma cofferdam, ndi madoko akumtunda ndi ma projekiti apamtunda.Malinga ndi magwiridwe antchito ndi mawonekedwe a geogrids,
Zomwe zimagwiritsidwa ntchito kwambiri mu polojekitiyi ndi:
(1) Chithandizo cha maziko.Itha kugwiritsidwa ntchito kulimbitsa maziko ofooka, kupititsa patsogolo mphamvu zonyamula maziko, ndikuwongolera kukhazikika kwa maziko ndi kukhazikika kosagwirizana.Pakadali pano, imagwiritsidwa ntchito kwambiri munjanji, misewu yayikulu, ndi mapulojekiti ena omwe ali ndi zofunikira zochepa pakuwongolera maziko.
(2) Kulimbitsa khoma losunga nthaka ndi kubweza.M'makoma omangirira nthaka, mphamvu ya ma geogrids ndi zolepheretsa kusamuka kwa tinthu tating'onoting'ono kumawonjezera kukhazikika kwa nthakayo.Pakadali pano, imagwiritsidwa ntchito makamaka kulimbikitsa makoma a njanji ndi misewu yayikulu, kubweza mitsinje, ndi ntchito zina zotsetsereka.
M'zaka zaposachedwa, chidwi chochulukirapo chaperekedwa pakumanga zowongolera kusefukira kwamadzi ndi ntchito zoteteza mabanki, ndipo kuchuluka kwa ntchito zomanga kwawonjezeka, zomwe zapangitsa kuti ma geogrid achuluke kwambiri pantchito zomanga.Makamaka m'mapulojekiti otchinga m'tawuni, pofuna kuchepetsa malo apansi a polojekitiyi ndikuwonjezera malo ofunika kwambiri, chitetezo cha malo otsetsereka a mitsinje nthawi zonse chimakhala chotsetsereka.Kwa mapulojekiti odzaza ndi nthaka ndi thanthwe, pamene zodzazazo sizingakwaniritse zofunikira zokhazikika kuti zitetezeke pamtunda, kugwiritsa ntchito nthaka yolimba sikungangokwaniritsa zofunikira zachitetezo cha tsetsereka, komanso kumachepetsa kukhazikika kwa thupi lozungulira. , ndi zabwino zauinjiniya.
