TOP realization - Secant pile wall used for securing a mounting shaft (SO 07-17)


Secant pile wall used for securing a mounting shaft (SO 07-17), construction of prolonged A line of Prague Underground (V. A)

A large circular mounting shaft was carried out in close proximity of the Vypich cross-roads (the BRE 1 construction site) to be used for assembly and subsequent fitting of boring shields for TBM at the construction of V. A line of Prague underground. Sheeting of the shaft forms a wall consisting of 88 pieces of 35 m long secant piles. The shaft diameter measures 24,8m (to the pile axis) and reaches the depth of approx. 34m under the modified terrain. As the excavation works progressed non-anchored reinforced concrete round straps T2, T3 and T4 were carried out at three height levels of the shaft. At the bottom area where the shaft goes through the tunnel two reinforced concrete straps were realised and anchored with six 8-strand anchors. The shaft function is temporary with its anticipated use for 4 years.
