FRP Cov kav dej

FRP cov kav dej, uas yog ib yam tseem ceeb ntawm cov khoom tsis yog{0}}cov khoom siv hlau sib xyaw, feem ntau yog ua los ntawm cov cob, iav fibers, thiab lwm yam fabrications. Cov khoom no nthuav tawm zoo heev corrosion kuj, abrasion tsis kam, siab compressive zog, lub teeb yuag zog, thiab yooj yim ntawm installation. Lawv nrhiav kev siv dav hauv kev tsim vaj tsev hauv nroog, kev tsim kho, kev lag luam tshuaj, kev tsim hluav taws xob, kev tiv thaiv ib puag ncig, thiab lwm yam. Peb cov yeeb nkab FRP dej muaj cov yam ntxwv zoo hydraulic, nws qhov Smooth inner nto (Manning coefficient n≈0.0089) txo cov dej tsis kam, muab cov peev txheej zoo tshaj li cov kav dej ib txwm muaj. Nyob rau hauv tib txoj kab uas hla ntawm cov yeeb nkab thiab kev thauj mus los, qhov ntim ntawm cov dej xa tuaj yog siab dua li cov kav dej ib txwm muaj
