产品描述
    武汉工大创新玻璃钢科技发展有限公司继越南项目后实施的又一大型项目,该项目为桥梁墩柱防撞设施的建设,该项目的难点在与水上的安装与后处理。具体技术要求工艺标准如下:
1、该玻璃钢工程为竹埠港湘江大桥防船撞设施项目。
2、玻璃钢桥梁防撞箱体为全玻璃钢结构,局部刚制件加强,采用分模 成型工艺制作。
3、玻璃钢桥梁防撞箱体外侧面厚度10mm,上表面5mm,其余均厚8mm,内部缓冲元件厚度4mm,所有结构件外包玻璃钢为5mm。
4、玻璃钢防撞箱的阴阳角全部为R20.
5、防护舷连接件采用5mm厚钢板加强,预制M30螺栓露头,内部全部用玻璃钢密封及加强,确保防水性能。
6、为不影响玻璃钢防撞箱体美观,在箱体内部预制吊装预埋件,预埋件由钢板和M24螺母焊接而成,后外包玻璃钢固定加强。
7、玻璃钢防撞箱体外面光亮,颜色为 交通红 
8、产品使用寿命:15年
