TB hydroelectric project roller compacted concrete dam, concrete pouring duration of only 19 months, a new domestic and international crushed concrete dam construction speed. In recent years, roller compacted concrete dam construction technology continues to progress, the degree of mechanization continues to be high, the dam concrete pouring period is generally 3 years, while the TB Hydropower Project dam in the construction process, the owner gives full play to the leading role in the time of 19 months on the completion of the dam concrete 2.25 million m³ of the pouring task, and the quality of the best, the use of concrete pouring intervals, the preparation of the silo bin surface taken out of the 26.5m world’s longest The longest core sample in the world was taken out from the surface of the preparation bin during the break of concrete pouring. In the construction of TB Hydropower Project roller compacted concrete dam, the owner led the implementation of a series of advanced technology and effective management means, such as through the warehouse large oblique layer rolling pouring technology, 9m high rising layer construction, continuous tilting pouring, into the warehouse way planning arrangement, fast across the corridor layer construction, etc., which laid an important foundation for the rapid construction of the dam. Project examples have proved that through advanced technology and effective management, the construction period of the roller compacted concrete dam has been greatly shortened, which creates prerequisite conditions for water storage, power generation and commissioning, and is of great significance in engineering practice.
