水工钢筋混凝土构件的保护层是否准确,直接影响构件的质量和耐久性。为了对构件的保护层进行非破损性的检查,我们参考了兄弟单位的图纸,加以改进,制作了一台钢筋保护层厚度测定仪,检查精度误差在 The accuracy of the protective layer of hydraulic reinforced concrete components directly affects the quality and durability of the components. In order to carry out non-destructive inspection of the protective layer of the component, we refer to the drawings of the fraternal unit and improve it. We have produced a steel protective layer thickness gauge. The inspection accuracy error is
