贵港航运枢纽工程电站装机容量为4X30MW，机组采用KVEARNER公司生产的灯泡贯流式发电机组，为河床式发电厂房．管型座是机组传力机构，为机组的重要部位，其管型座周边二期混凝土浇筑质量，直接关系机组的正常运行．同时，由于周边结构复杂、浇筑面积窄小、施工困难，且技术要?
Guigang shipping hub power plant installed capacity of 4X30MW, the unit uses KVEARNER bulb tubular turbine generator for the riverbed power plant. The tubular seat is the force transmission mechanism of the unit, which is an important part of the unit. The quality of the second stage concrete pouring around the tubular seat directly relates to the normal operation of the unit. At the same time, due to the complexity of the surrounding structure, the pouring area is small, difficult construction, and technology to?
