Uniaxial geogrids, tshwj xeeb tshaj yog PP (polypropylene)uniaxial geogrids, yog ib feem tseem ceeb ntawm niaj hnub civil engineering thiab kev tsim kho tej yaam num. Cov geosynthetics no yog tsim los muab kev txhawb zog thiab stabilization nyob rau hauv ntau yam kev siv, nrog rau kev tsim kho, tuav cov phab ntsa thiab av stabilization. To taub lub zog ntawmuniaxial geogridsNws yog ib qho tseem ceeb rau engineers thiab designers los xyuas kom meej lub neej ntev thiab kev ua tau zoo ntawm lawv tej yaam num.
Kev sib xyaw thiab cov qauv
PP uniaxial geogridyog ua los ntawm high-density polypropylene, paub txog nws zoo heev tensile zog thiab durability. Cov txheej txheem tsim khoom suav nrog extruding cov polymer rau hauv cov qauv zoo li mesh, tsim kom muaj cov kab sib txuas sib txuas. Qhov kev tsim no tso cai rau cov geogrid faib cov khoom thauj mus rau thaj chaw loj dua, txo kev ntxhov siab ntawm cov av hauv qab lossis cov sib sau. Lub uniaxial configuration txhais tau hais tias lub geogrid feem ntau yog tsim los tiv thaiv tensile rog nyob rau hauv ib qho kev taw qhia, ua rau nws tshwj xeeb tshaj yog zoo rau cov kev siv uas loads yog siv nyob rau hauv ib tug linear zam.
Cov yam ntxwv muaj zog
Lub zog ntawm uniaxial geogrid feem ntau ntsuas los ntawm nws lub zog tensile, uas yog qhov siab tshaj plaws tensile quab yuam (rub lub zog) cov khoom tuaj yeem tiv taus ua ntej ua tsis tiav. Cov cuab yeej no yog qhov tseem ceeb hauv kev txiav txim siab kev ua haujlwm ntawm geogrids hauv qab load. Lub zog tensile ntawmpolypropylene uniaxial geogridsNws txawv nyob ntawm seb cov khoom tshwj xeeb thiab nws qhov kev thov. Feem ntau, lub zog tensile ntawm cov geogrids no txawv ntawm 20 kN / m mus rau ntau tshaj 100 kN / m, nyob ntawm qhov tuab thiab tsim ntawm geogrid.
Ntxiv nrog rau lub zog tensile, lwm yam xws li elastic modulus thiab elongation thaum so kuj tseem ceeb. Lub elastic modulus qhia ntau npaum li cas cov geogrid deforms nyob rau hauv load, thaum lub elongation ntawm break muab kev pom rau cov khoom ductility. Lub elongation siab dua thaum so txhais tau hais tias lub geogrid tuaj yeem ncab ntau dua ua ntej tsis ua haujlwm, uas yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov uas yuav tsum tau txav mus rau hauv av.
Daim ntawv thov thiab cov txiaj ntsig
Lub zog ntawmuniaxial geogridsua rau lawv haum rau ntau yam kev siv. Hauv kev tsim kho txoj kev, lawv feem ntau siv los ntxiv dag zog rau cov txheej txheem subgrade, txhim kho kev faib khoom thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav. Hauv kev tuav cov ntawv thov phab ntsa, uniaxial geogrids pab kom ruaj khov hauv av thiab tiv thaiv kev txav mus los, ua kom muaj kev ncaj ncees.
Ib qho ntawm qhov zoo ntawm kev sivPP uniaxial geogridyog lub peev xwm los txhim kho kev ua tau zoo tag nrho ntawm cov qauv av. Los ntawm kev muab lub zog tensile ntxiv, cov geogrids no tuaj yeem txo qhov kev sib haum xeeb thiab deformation, ua rau cov vaj tse nyob ntev thiab txhim khu kev qha. Tsis tas li ntawd, lawv qhov hnyav hnyav ua rau lawv yooj yim los tuav thiab txhim kho, txo cov nqi zog thiab sijhawm tsim kho.
nyob rau hauv xaus
Hauv cov ntsiab lus, lub zog ntawm uniaxial geogrids, tshwj xeeb tshaj yog polypropylene uniaxial geogrids, yog qhov tseem ceeb hauv lawv cov txiaj ntsig zoo li cov ntaub ntawv txhawb zog hauv kev siv engineering hauv kev siv pej xeem. Vim tias tensile zog sib txawv, engineers yuav tsum xaiv qhov tsim nyog geogrid raws li cov kev cai tshwj xeeb ntawm qhov project. Los ntawm kev nkag siab txog cov khoom muaj zog thiab cov txiaj ntsig ntawm uniaxial geogrids, cov kws tshaj lij tuaj yeem txiav txim siab paub uas yuav txhim kho cov kav ntev thiab kev ua haujlwm ntawm lawv cov qauv. Raws li qhov kev thov kom muaj kev ruaj ntseg, kev tsim kho kom zoo txuas ntxiv mus ntxiv, lub luag haujlwm ntawm uniaxial geogrids hauv kev tsim vaj tsev niaj hnub no yuav tsis muaj qhov tseem ceeb dua.
