Uniaxial geogrids, makamaka PP (polypropylene)uniaxial geogrids, ndi mbali yofunika kwambiri ya zomangamanga zamakono ndi zomangamanga. Ma geosynthetics awa adapangidwa kuti apereke chilimbikitso ndi kukhazikika m'njira zosiyanasiyana, kuphatikiza kupanga misewu, makoma osungira komanso kukhazikika kwa nthaka. Kumvetsetsa mphamvu yauniaxial geogridsndizofunikira kwa mainjiniya ndi opanga kuti awonetsetse kuti ntchito zawo zizikhala zazitali komanso zogwira mtima.
Kapangidwe ndi kapangidwe
PP uniaxial geogridamapangidwa ndi polypropylene yolimba kwambiri, yomwe imadziwika ndi mphamvu zake zolimba komanso zolimba. Kupanga kumaphatikizapo kutulutsa polima kukhala chofanana ndi ma mesh, ndikupanga nthiti zingapo zolumikizana. Kapangidwe kameneka kamapangitsa kuti geogrid igawire katundu pamalo okulirapo, kuchepetsa kupsinjika kwa nthaka yapansi panthaka kapena kuphatikizika. Kukonzekera kwa uniaxial kumatanthauza kuti geogrid imapangidwa kuti igwirizane ndi mphamvu zosunthika mbali imodzi, zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri pamapulogalamu omwe katundu amayikidwa motsatira mzere.
Mphamvu makhalidwe
Mphamvu ya uniaxial geogrid nthawi zambiri imayesedwa ndi mphamvu yake yokhazikika, yomwe ndi mphamvu yayikulu kwambiri (mphamvu yokoka) zomwe zimatha kupirira zisanalephere. Katunduyu ndi wofunikira kwambiri pakuzindikira momwe ma geogrid amagwirira ntchito. Mphamvu yamanjenje yapolypropylene uniaxial geogridszimasiyana mosiyanasiyana kutengera mtundu wa chinthucho komanso ntchito yake. Nthawi zambiri, kulimba kwa ma geogrid awa kumayambira pa 20 kN/m kufika pa 100 kN/m, kutengera makulidwe ndi kapangidwe ka geogrid.
Kuphatikiza pa kulimba kwamphamvu, zinthu zina monga elastic modulus ndi elongation panthawi yopuma ndizofunikanso. Elastic modulus imasonyeza kuchuluka kwa geogrid yomwe imasokonekera, pamene kutalika kwa nthawi yopuma kumapereka chidziwitso cha ductility. Kutalikirana kwambiri panthawi yopuma kumatanthauza kuti geogrid imatha kutambasula kwambiri isanalephereke, zomwe zimakhala zopindulitsa pamagwiritsidwe ntchito pomwe kusuntha kwapansi kumayembekezeredwa.
Mapulogalamu ndi Ubwino
Mphamvu yauniaxial geogridsamawapangitsa kukhala oyenera ntchito zosiyanasiyana. Popanga misewu, nthawi zambiri amagwiritsidwa ntchito kulimbitsa gawo laling'ono, kukonza kugawa katundu komanso kuchepetsa chiopsezo cha kulephera kwapanjira. Posunga khoma, ma geogrids a uniaxial amathandizira kukhazikika kwa nthaka ndikuletsa kusuntha kozungulira, kuonetsetsa kukhulupirika kwadongosolo.
Mmodzi mwa ubwino waukulu ntchitoPP uniaxial geogridndi kuthekera kopititsa patsogolo ntchito yonse ya nthaka. Popereka mphamvu zowonjezera, ma geogrid awa amatha kuchepetsa kukhazikika ndi kusinthika, kupangitsa kuti zomangamanga zizikhalitsa komanso zodalirika. Kuphatikiza apo, mawonekedwe awo opepuka amawapangitsa kukhala osavuta kuwagwira ndikuyika, kuchepetsa ndalama zogwirira ntchito komanso nthawi yomanga.
Pomaliza
Mwachidule, mphamvu ya uniaxial geogrids, makamaka polypropylene uniaxial geogrids, ndiye chinthu chofunikira kwambiri pakuchita bwino kwawo ngati zida zolimbikitsira ntchito zama engineering. Chifukwa mphamvu zamakokedwe zimasiyana mosiyanasiyana, mainjiniya ayenera kusankha geogrid yoyenera kutengera zomwe polojekitiyi ikufuna. Pomvetsetsa mphamvu ndi mapindu a uniaxial geogrids, akatswiri amatha kupanga zisankho zomwe zingapangitse kulimba ndi magwiridwe antchito awo. Pomwe kufunikira kokhazikika, njira zomangira zogwirira ntchito zikupitilira kukula, gawo la uniaxial geogrids mu uinjiniya wamakono mosakayikira likhala lofunikira kwambiri.
