Ma geogrids akhala gawo lofunikira kwambiri pa zomangamanga ndi zomangamanga, makamaka pakugwiritsa ntchito kulimbikitsa ndi kukhazikika kwa nthaka. Pakati pa mitundu yosiyanasiyana ya geogrids yomwe ilipo,PP Uniaxial Geogridsndi Uniaxial Plastic Geogrids amagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zawo komanso kulimba. Komabe, posankha geogrid yoyenera pulojekiti, ndikofunikira kumvetsetsa kusiyana pakati pa MD (Machine Direction) ndi XMD (Cross Machine Direction), chifukwa izi zitha kukhudza kwambiri magwiridwe antchito.
Kodi Geogrids ndi chiyani?
Ma geogrids ndi zida za polymeric zomwe zimagwiritsidwa ntchito kulimbikitsa nthaka ndi zinthu zina. Amapangidwa kuchokera ku polyethylene yapamwamba kwambiri (HDPE) kapena polypropylene (PP), zomwe zimapereka mphamvu zolimba komanso zolimba.PP Uniaxial Geogrids, makamaka, amapangidwa kuti apereke mphamvu zapamwamba kumbali imodzi, kuwapanga kukhala abwino kwa ntchito monga kusunga makoma, kukhazikika kwa malo otsetsereka, ndi kumanga misewu.
Kufunika kwa MD ndi XMD
Pokambiranageogrids, MD ndi XMD amatanthawuza kulunjika kwa mphamvu ya geogrid.
MD (Makina Direction): Uku ndi kumene geogrid amapangidwira. Kulimba kwamphamvu kotereku kumakhala kokulirapo chifukwa njira yopanga imagwirizanitsa maunyolo a polima kuti apereke mphamvu zambiri. ZaPP Uniaxial Geogrids, MD ndiyofunikira pakugwiritsa ntchito komwe katunduyo amayikidwa mbali iyi, monga makoma oyima kapena otsetsereka.
XMD (Cross Machine Direction): Izi zikutanthauza kulimba kwa geogrid komwe kumayenderana ndi njira yamakina. Ngakhale mphamvu za XMD nthawi zambiri zimakhala zotsika kuposa mphamvu za MD, ndizofunikirabe kuziganizira, makamaka pamapulogalamu omwe katundu angagwiritsidwe ntchito kuchokera kumayendedwe angapo.
Kusiyana Kwakukulu Pakati pa MD ndi XMD
Mphamvu Yamphamvu: Kusiyana kwakukulu pakati pa MD ndi XMD ndiko kulimba kwamphamvu. MD nthawi zambiri imawonetsa kulimba kwamphamvu kwambiri chifukwa cha kulumikizana kwa maunyolo a polima panthawi yopanga. Izi zimapangitsa kuti zikhale zoyenera kwambiri pazogwiritsa ntchito pomwe katundu woyambirira amagwiritsidwa ntchito pamakina.
Kugawa Katundu: Muzinthu zambiri zamainjiniya, zolemetsa sizimayikidwa mbali imodzi. Kumvetsetsa mawonekedwe a XMD ndikofunikira pakuwonetsetsa kuti geogrid imatha kugawa katundu mokwanira mbali zosiyanasiyana, zomwe ndizofunikira kwambiri m'nthaka zovuta.
Kukwanira kwa Kugwiritsa Ntchito: Kusankha pakati pa MD ndi XMD kungathe kukhudza kukwanira kwa geogrid pamapulogalamu enaake. Mwachitsanzo, ngati pulojekiti ikukhudzana ndi katundu wambiri, geogrid yokhala ndi malireMDndiZithunzi za XMDmphamvu zingakhale zofunikira kuonetsetsa bata ndi ntchito.
Zolinga Zopanga: Mainjiniya ayenera kuganizira za MD ndi XMD popanga projekiti. Mayendedwe a geogrid atha kukonzedwa bwino posankha chinthu chomwe chimakwaniritsa zofunikira zamtundu uliwonse mbali zonse ziwiri.
Mapeto
Mwachidule, kumvetsetsa kusiyana pakati pa MD ndi XMD mu geogrids, makamaka muPP Uniaxial Geogridsndi Uniaxial Plastic Geogrids, ndizofunika kuti polojekiti ichitike bwino. Mphamvu zamakina pamakina amakina nthawi zambiri zimakhala zapamwamba, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zinazake, pomwe mphamvu zamakina amtanda zimagwira ntchito yofunika kwambiri pakugawa katundu komanso kukhazikika kwathunthu. Poganizira mozama zinthuzi, mainjiniya amatha kusankha geogrid yoyenera kuti apititse patsogolo magwiridwe antchito komanso moyo wautali wama projekiti awo.
