三峡电站机组埋件安装质量控制

Quality control of unit embedded parts for Three Gorges hydropower station

三峡机组从出力和尺寸上已达到或超过世界已有水平,已安装完成的机组埋件焊接一次合格率在97%以上,达到三峡工程质量的预期目标。文章所介绍的是机组埋件安装质量控制过程,可供其它工程参考。

In view of size and output, the units for TGP have reached and surpassed the world level. As the welding qualification rate of unit embedded parts is over 97% except for the embedded parts with manufacturing defects, the erection quality for TGP has reached the expected objective through the concerted efforts of the owner, supervisor and contractor. The paper discusses the erection quality control of unit embedded parts.
