Abstract:

The vertical shaft of Langya Mountain pumped storage power station is 70m in depth, 20m and 18.6m in outer diameter and inner diameter. The consolidation grouting of the shaft was completed by the aid of hoisting system with sinking stage, suspension cage and winch. The grouting work was successfully completed by optimizing the construction scheme, reasonably organizing construction, establishing perfect rules and regulations, strengthening the vocational training and strictly carrying out construction safety measures.
