Bidirectional geogrid yog cov khoom siv geosynthetic feem ntau ua los ntawm cov khoom hnyav molecular polymers xws li high-density polyethylene (HDPE) lossis polypropylene (PP). Nws cov yam ntxwv feem ntau suav nrog cov ntsiab lus hauv qab no:
1. Bidirectional tensile kev ua tau zoo: Bidirectional geogrids muaj lub zog tensile siab thiab nruj, uas tuaj yeem faib cov khoom sib npaug ntawm ob qho kev qhia, txhim kho cov kabmob muaj peev xwm thiab ruaj khov ntawm cov av.
2. Cov tshuaj tiv thaiv siab: Bidirectional geogrids muaj cov tshuaj tiv thaiv zoo thiab tuaj yeem siv tau ntev hauv thaj chaw acidic thiab alkaline yam tsis muaj tshuaj lom neeg corrosion.
3. Muaj zog durability: Bidirectional geogrids muaj kev ruaj khov zoo thiab tuaj yeem tiv taus cov teebmeem ntawm ultraviolet hluav taws xob, oxidation, thiab kev laus rau lub sijhawm ntev, tswj lawv cov khoom siv kho tshuab thiab kev pabcuam lub neej.
4. Zoo permeability: bidirectional geogrids muaj ib tug tej yam kev mob ntawm permeability, tso cai rau cov dej nyob rau hauv cov av los ntawm thiab tiv thaiv cov dej tsub zuj zuj thiab av liquefaction.
Cov kev siv tseem ceeb ntawm bidirectional geogrids suav nrog:
1. Kev siv av ntxiv: Bidirectional geogrids tuaj yeem siv los txhawb cov av thiab txhim kho nws tag nrho lub zog thiab ruaj khov. Nws tuaj yeem ua kom lub zog tensile thiab shear zog ntawm cov av los ntawm kev cuam tshuam nrog nws, tiv thaiv deformation thiab kev puas tsuaj ntawm cov av.
2. Reinforced subgrade: Bidirectional geogrids tuaj yeem siv los txhim kho subgrade, txhim kho cov kabmob muaj peev xwm thiab kev ruaj ntseg ntawm txoj kev pavement. Nws tuaj yeem cuam tshuam cov khoom thauj, txo txoj kev daws teeb meem thiab deformation, thiab txuas ntxiv kev pabcuam lub neej ntawm txoj kev.
3. Kev tiv thaiv embankment: Bidirectional geogrids tuaj yeem siv los tiv thaiv embankments thiab txhim kho lawv cov kev tiv thaiv zawv zawg. Nws tuaj yeem tiv thaiv lub pas dej los ntawm kev puas tsuaj nyob rau hauv qhov kev txiav txim ntawm cov dej ntws yaig thiab kev hloov mus rau sab nraud.
4. Kev txhim kho av: Bidirectional geogrids tuaj yeem siv rau kev txhim kho av los txhim kho lub cev thiab kev ua haujlwm engineering ntawm av. Nws tuaj yeem ua kom muaj zog thiab ruaj khov ntawm cov av, txo cov av sib haum xeeb thiab nthuav dav.
Feem ntau, bidirectional geogrid yog cov khoom siv geosynthetic multifunctional siv dav hauv engineering engineering, dej txuag engineering, tsheb thauj mus los engineering, ib puag ncig engineering thiab lwm yam kev lag luam, ua lub luag haujlwm hauv kev txhawb nqa, txhim kho, tiv thaiv thiab txhim kho av.
