Nekushandiswa kwakakura kweGFRP grillage muinjiniya yehurumende, tsvakiridzo yebasa rayo uye nzira yekushandisa muinjiniya yehurumende yakafambiswa mberi. Muzviitiko zvakasiyana-siyana, pane zvakasiyana-siyana zvinodiwa zveFRP grille inoshandiswa. Asi kazhinji, kupfuura zvese, zvinoda hupenyu hurefu, kazhinji makore, kunyange makumi emakore. Hunhu hwezvinhu hunodiwawo kuti huve hwakaoma uye huremu pachikamu chimwe chete nharaunda inorema (100-500g/m2 pamusoro). Zvimwe zvinoda kuyerera kwemvura kwakanaka uye kuchengetedzwa kwenzwi, zvimwe zvinoda kusamira kwemvura. Nekudaro, zvinodikanwa kuti unzwisise ake emuviri zvimiro, zvemichina zvimiro, uye hydraulic zvimiro
1. Zvinhu zvemuviri
(1) isotropy: simba, kuoma uye elasticity ye isotropy zvakafanana.
(2) homogeneity: ukobvu uye huremu hwenzvimbo yeyuniti inofanira kunge yakafanana.
(3) kugadzikana: inogona kuramba kuora kweiyo organic matter, acid uye alkali muvhu nheyo, shanduko yekushisa uye kuita kwezvipembenene, mabhakitiriya nezvimwe zvisikwa. Isati yashandiswa GFRP grille, inoda kusungirirwa kwenguva yakati, saka inodawo kusapisa kupisa kune zuva (ultraviolet ray) uye mvura.
2. Mechanical properties
Simba uye elasticity akakosha emuchina vakomana, nekuti kugara pane hombe t ivhu zvinhu zvakaunganidzwa pane fiberglass grid. Naizvozvo, iyo GFRP grille inofanirwa kuve neimwe simba uye anti-grille deformation zvivakwa. Kune zvakare kugona kutsungirira mitoro yakadzika, yakadai sekuputika uye kubvarura.
3. Hydraulic performance
Iyo pore saizi yakaumbwa pakati pemafiber uye ukobvu hweFRP grillage ine simba guru pakuita kweFRP grillage drainage uye kusefa. Kukura kwepore hakufaniri kungoita kuti mvura ipfuure zvakanaka, asiwo haigoni kukonzera kuputika kwevhu, uye panguva imwechete, ukuru hwepore hunofanira kunge hwakagadzikana pasi pekuita kwemutoro.
Kuita kweFRP grille kunoita kuti ishandiswe zvakanaka muinjiniya yehurumende.
