Ma hydraulic properties ndi zofunikira zamakina a FRP grille

Ndi kugwiritsa ntchito kwakukulu kwa GFRP grillage mu engineering civil, kafukufuku wa ntchito yake ndi njira yogwiritsira ntchito mu engineering Civil engineering yapita patsogolo.Muzochitika zosiyanasiyana, pali zofunikira zosiyanasiyana zogwirira ntchito pa grille ya FRP yomwe imagwiritsidwa ntchito.Koma zambiri, koposa zonse, zimafuna moyo wautali, nthawi zambiri zaka, ngakhale makumi.Ubwino wa zinthuzo umafunikanso kuti ukhale wolimba komanso kulemera kwa gawo lililonse kumakhala kolemetsa (100-500g/m2 pamwambapa).Zina zimafuna madzi osungunuka bwino ndi kukonzanso phokoso, zina zimafuna kuti madzi asawonongeke.Chifukwa chake, ndikofunikira kumvetsetsa mawonekedwe ake, mawonekedwe ake amakina, komanso mphamvu zama hydraulic

1. Zinthu zakuthupi

(1) isotropy: mphamvu, kuuma ndi kusungunuka kwa isotropy ndizofanana.

(2) homogeneity: makulidwe ndi kulemera kwa gawo lagawo liyenera kukhala lofanana.

(3) bata: akhoza kukana dzimbiri zinthu organic, asidi ndi zamchere mu nthaka maziko, kusintha kwa kutentha ndi zochita za tizilombo, mabakiteriya ndi zolengedwa zina.Grille ya GFRP isanayambe kugwiritsidwa ntchito, imayenera kuwunjikidwa kwa nthawi ndithu, choncho iyeneranso kukhala yosagwirizana ndi kutentha kwa dzuwa (ultraviolet ray) ndi mvula.

2. Makina katundu

Mphamvu ndi kukhazikika ndizofunikira kwambiri anyamata amakanika, chifukwa kukhala pa dothi lalikulu la t zimawunjikana pa gridi ya fiberglass.Chifukwa chake, grille ya GFRP iyenera kukhala ndi mphamvu zina ndi anti-grille deformation.Palinso luso lotha kupirira katundu wokhazikika, monga kuphulika ndi kung'amba.

3. Kuchita kwa Hydraulic

Kukula kwa pore komwe kumapangidwa pakati pa ulusi ndi makulidwe a FRP grillage kumakhudza kwambiri magwiridwe antchito a FRP grillage ngalande ndi kusefera.Kukula kwa pore sikuyenera kupangitsa kuti madzi azitha kuyenda bwino, komanso sikungayambitse kukokoloka kwa nthaka, ndipo panthawi imodzimodziyo, kukula kwa pore kuyenera kukhala kokhazikika pansi pa katundu.

Kuchita kwa FRP grille kumapangitsa kuti ikhale yogwiritsidwa ntchito bwino mu engineering ya Civil engineering.
