geogrid yog ib yam khoom siv geosynthetic uas yog siv rau kev txhim kho thiab ruaj khov hauv ntau yam kev tsim vaj tsev thiab kev tsim kho vaj tse. Nws feem ntau yog tsim los ntawm cov ntaub ntawv muaj zog polymer, xws li polyester lossis polypropylene, thiab muaj cov qauv zoo li kab sib chaws nrog cov qhov chaw tsis tu ncua.
Geogrids feem ntau yog siv los txhim kho lub zog thiab ruaj khov ntawm cov av, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas tsis muaj zog lossis tsis ruaj tsis khov. Lawv feem ntau siv hauv cov ntawv thov hauv qab no:
1. Cov phab ntsa tuav: Geogrids tuaj yeem ntsia tau kab rov tav hauv cov txheej hauv av kom txhim kho kev ruaj ntseg ntawm cov phab ntsa. Lawv muab lub zog tensile thiab tiv thaiv cov av txav, txo kev pheej hmoo ntawm phab ntsa tsis ua haujlwm.
2. Kev ruaj ntseg ntawm txoj kab nqes: Geogrids yog siv los txhawb cov nqes hav thiab tiv thaiv av yaig thiab av. Lawv muab tso rau hauv cov av txheej los ua kom cov shear tsis kam thiab tag nrho stability ntawm txoj kab nqes.
3. Kev tsim kho txoj kev thiab txoj kev pavement: Geogrids feem ntau tau muab tso rau hauv txoj kev thiab cov txheej txheem pavement kom faib cov khoom thauj thiab txo rutting thiab tawg. Lawv pab txhim kho cov kabmob muaj peev xwm thiab lub neej ntev ntawm cov txheej txheem.
4. Embankments thiab foundations: Geogrids yog siv los txhawb cov embankments thiab foundations, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj mos los yog xoob av. Los ntawm kev muab lub zog ntxiv thiab kaw, lawv tiv thaiv kev sib haum xeeb thiab txhim kho kev ruaj ntseg tag nrho.
5. Kev tsim kho hauv av: Geogrids tau ua haujlwm hauv kev tsim kho av txhawm rau txhim kho qhov ruaj khov thiab muaj peev xwm thauj khoom ntawm cov khoom pov tseg. Lawv pab tiv thaiv deformation thiab tswj kev ncaj ncees ntawm qhov chaw pov tseg.
