我省的水利工程中有为数众多的灌区渠系、江海堤围、挡潮排洪设施和纳潮闸。而闸门是这些水利工程的重要组成部分。由于这些闸门长期处于干湿交替、浸没水下高速水流等环境中,受到不同水质、气体、阳光、尘埃和水生物的腐蚀,以及泥沙和其他漂浮物的冲击、震动、摩擦,如果采用普通的材料制造闸门或采用一般的防护(如涂铁红粉拌粘结油、煤焦油、沥青、油漆等),受破坏严重,其损坏率极高,一些较严重的几乎三、五年就告报废;但若采用玻璃钢防护闸门与玻璃钢闸门,则可以有效地减少由于 There are a large number of irrigated canals, river embankments, tidal flats and flood gates and floodplains in the province’s water conservancy projects. The gate is an important part of these water projects. Due to the long-term dry and wet conditions, these gates are subject to corrosion due to different water, gases, sunshine, dust and aquatic organisms, as well as the impact, vibration and friction of sediment and other floating objects if they are ordinary Of the gate material or the use of general protection (such as iron oxide red mix with oil, coal tar, asphalt, paint, etc.), severely damaged, the high rate of damage, some more serious almost three or five years to scrap ; But if the use of FRP protective gate and FRP gate, you can effectively reduce due to
