Abstract:

Due to the site restraints, the TBM for the diversion tunnel of Jinping Hydropower Station has to be assembled in the assembly chamber. The diameter of the TBM reaches 12.43m, therefore the TBM assembly chamber has large crosssection, huge working quantity, complex construction process and high construction quality requirements. The crosssection, length, reinforcement types, lining structures and bridge crane foundations of the assembly chamber are proposed on basis of the geological conditions, TBM structures, assembly methods, hoisting facility requirements and available construction methods. Countermeasures are proposed for the construction of the assembly chamber so as to ensure the quality, safety and progress of the construction. The successful design and construction of the TBM assembly chamber have laid a good foundation for the assembly of the largediameter TBM in the chamber.

Key words: Jinping Hydropower Station, TBM, assembly chamber, design, construction
