近年来,我国北京、天津、保定、新乡等地已用玻璃钢管成井二十余眼。新乡市自来水公司于1975年在北京玻璃钢研究所和国家地质总局水文地质技术方法研究队的协助下进行了玻璃钢滤水管成井试验之后,又用该管成井八眼。实践证明,玻璃钢井管与常用的铸铁井管、混凝土井管、塑料管等相比,具有重量轻、强度高、结构及制造简单、施工方便、耐腐蚀等优点。一、玻璃钢井管简介玻璃钢井壁实管是用浸胶的玻璃丝布带缠绕制成;玻璃钢滤水管是采用多孔架桥式结构,制造时,先将浸有环氧树脂粘接剂的无捻玻璃丝粗纱加捻后,按一定间距在金属
In recent years, Beijing, Tianjin, Baoding, Xinxiang and other places have used more than 20 wells made of glass steel pipe. Xinxiang Water Supply Company conducted the well test of glass fiber reinforced plastics water filtration pipe in 1975 with the help of Beijing FRP Research Institute and the National Geological Survey of Hydrogeology Technical Method Research Team. It also used the pipe to make eight wells. Practice has proved that compared with commonly used cast-iron well pipes, concrete well pipes, and plastic pipes, FRP well pipes have the advantages of light weight, high strength, simple structure and manufacturing, convenient construction, and corrosion resistance. 1. Introduction of FRP Well Pipe FRP pipe wall pipe is made by dipping glass fiber tape with dipping; FRP water filter pipe adopts multi-hole bridge structure. When it is manufactured, it will be impregnated with epoxy resin adhesive. After the glass roving is twisted, press the metal at a certain distance
