俄公堡水电站压力钢管组焊和安装技术措施

摘要

根据俄公堡水电站整节压力钢管运输受限制的施工现场实际情况，通过现场充分勘查，从安全、经济和缩短工期等多方面综合、科学地分析和论证，对俄公堡水电站剩余压力钢管运输、组焊和安装工艺详细编制，采取了分成两半运输的特殊措施，技术方案实施后证明了其可行性。%As the transportation of the penstock in a whole section is restricted, techniques for transportation, assembly welding and installa-tion of the rest penstocks are prepared in detail after the complete investigation as well as demonstrated and analyzed comprehensively and sci-entifically in terms of safety, cost and shortening construction period. A penstock to be transported in two sections is proposed. The technical proposal after being implemented is proved feasible.
