Application of Jacked Deck to Launch Boxes

Page 24: JAMES THOMSON C. ENG JACKED STRUCTURES SA  JACKED STRUCTURES SA A New Approach to Constructing Underground Stations

• By breaking down the process into elements reduces the exposed soil face • Minimises jacking forces and reaction arrangements.• Continuous support of the excavation with a full structural lining • Surface settlement is minimal • Use of precast units allows higher quality construction

 Advantages of the Jacked Arch

and Deck Approach

Page 25: JAMES THOMSON C. ENG JACKED STRUCTURES SA  JACKED STRUCTURES SA A New Approach to Constructing Underground Stations

• A wide range of geometry and configurations • Installation to very close line and level tolerances• Methods are applicable to both shallow and deep structures• Provides greater clear spans over much longer drive lengths.• Small launch platform area
