玻璃钢夹砂管在某核电站淡水输水工程中的应用

Application of Sand Filled Fiber Glass Reinforced Plastic Pipe in Raw Water Conveyance Line for a Nuclear Power Station

根据某核电站淡水输水管线的布线位置、供水压力、土壤性质 ,及其施工维护和材料供应条件等 ,经比较最终选择了玻璃钢夹砂管。对全长 38 5km输水管线工程设计中遇到的过河、连接管、中间加压泵站、水锤设防诸技术问题作了简介 ;对现场施工中遇到的沟槽积水、塌方、钢套管。

The sand filled fiber glass reinforced plastic pipe was adopted for the raw water conveyance line in a nuclear power station. This decision was confirmed under investigation and comparison of many factors such as the location of the pipeline, the water pressure, the nature and corrosion of the soil, construction convenience and market availability. Some key technical issues faced in design of this pipeline with full distance of 38 5 km, including the river crossings, connection lines, intermediate boosting pumping stations and water hammer buffering etc are presented in this paper briefly. Beside these also the treatment of field engineering affairs such as the flooding of trench, soil slip, installation of steel sleeve, ground base treatment in various soil conditions and set up of pipe abutments are discussed in detail.
