Abstract
TB hydropower station dam is a roller compacted concrete gravity dam with a height of 158m.The dam has three levels of low,medium,and high corridors arranged at elevations of 1586m,1640m,and 1695m.After the installation of the formwork for the corridor layer of the dam,the large warehouse surface is divided into multiple independent warehouse surfaces.Coupled with the interference of the bottom corridor and consolidation grouting,the roller compacted concrete construction of the corridor layer is the most difficult and longest straight-line construction of the dam.TB hydropower station has effectively accelerated the construction speed of the corridor layer through technological innovations in consolidation grouting,corridor storage,and"crossing"the corridor,and completed the roller compacted concrete construction of the middle corridor layer of the dam in only 20 days.关键词
