Construction of Underground Pump House Cavern in Medium Stress Condition—A Case Study from India
Underground pump house cavern for the lifting of 2.0 TMC water per day is being constructed in the Telangana State of India. Concurrently with the excavation of the pump house, 3D engineering geological mapping was carried out of the heading portion for rock mass classification and recommendation of support. The direction of the longest axis of the pump house was finalized based on the in situ hydrofrac testing inside the borehole. Classification of rock mass was done following the Tunnel Quality Index ‘Q’ method. Ground condition was non-squeezing; accordingly, Q-values were used for the estimation of roof support and walls support pressure. Based on NMT technology and site geological conditions, rock support arrangements were recommended for structural stability of crown and walls. Using the integrated approach, the capacity of the support system is determined to appraise the efficacy of the planned support system.
