Nrog rau kev siv dav ntawm GFRP grillage hauv civil engineering, kev tshawb fawb ntawm nws txoj haujlwm thiab kev siv txoj hauv kev hauv engineering tau ua tiav. Hauv ntau qhov xwm txheej, muaj cov kev xav tau sib txawv rau FRP grille siv. Tab sis feem ntau ntawm tag nrho cov, nws yuav tsum tau lub neej ntev, feem ntau xyoo, txawm kaum xyoo. Qhov zoo ntawm cov khoom tseem yuav tsum tau ua kom tawv thiab qhov hnyav ntawm ib chav tsev yog qhov hnyav (100-500g / m2 saum toj no). Qee qhov xav tau dej zoo seepage thiab zoo tu, qee qhov xav tau dej impermeability. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nkag siab txog nws lub cev lub cev, cov khoom siv hluav taws xob, thiab cov khoom siv hydraulic
1. Lub cev muaj zog
(1) isotropy: lub zog, nruj thiab elasticity ntawm isotropy yog tib yam.
(2) homogeneity: lub thickness thiab qhov hnyav ntawm chav tsev yuav tsum sib xws.
(3) kev ruaj ntseg: nws tuaj yeem tiv thaiv corrosion ntawm cov organic teeb meem, kua qaub thiab alkali hauv av hauv paus, kev hloov ntawm qhov kub thiab txias thiab kev ua ntawm kab, kab mob thiab lwm yam tsiaj. Ua ntej GFRP grille siv, nws yuav tsum tau muab tso rau ib lub sijhawm, yog li nws kuj yuav tsum tau ua kom sov-resistant rau lub hnub (ultraviolet ray) thiab los nag.
2. Mechanical zog
Lub zog thiab elasticity yog qhov tseem ceeb ntawm cov neeg kho tshuab, vim tias nyob ntawm cov ntaub ntawv loj t av tau muab tso rau ntawm daim phiaj fiberglass. Yog li, GFRP grille yuav tsum muaj qee lub zog thiab tiv thaiv cov hniav deformation. Kuj tseem muaj peev xwm tiv taus cov khoom hnyav, xws li tawg thiab tawg.
3. Kev ua haujlwm hydraulic
Qhov pore loj tsim ntawm fibers thiab tuab ntawm FRP grillage muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm FRP grillage kua thiab pom. Qhov pore loj yuav tsum tsis tsuas yog ua kom cov dej ntws mus zoo, tab sis kuj tsis tuaj yeem ua rau av yaig, thiab tib lub sijhawm, qhov pore loj yuav tsum tau ruaj khov nyob rau hauv qhov kev txiav txim ntawm kev thauj khoom.
Kev ua tau zoo ntawm FRP grille ua rau nws siv tau zoo hauv kev tsim vaj tsev.
