Method for constructing an underground parking area submerged in a variable ground-water table or other similar device

摘要

The invention relates to a method for constructing an underground parking area submerged in a variable ground-water table in which the raft 1 is anchored in the ground 2 by means of circular tie piles 3 which are injected 10. The device consists of circular metal piles 3 which are driven and injected 10 into the ground 2. A welded metal plate 4 on these piles 3 transmits the vertical compression or tension forces to the raft 1 and to its reinforcement 5 arranged under the columns 11. The raft 1 is installed after the installation of a layer of draining materials 8, an impermeable film 7 and a layer of blinding concrete 6. The method is, according to the invention, intended for the construction of parking areas for motor vehicles in permeable grounds containing a variable ground-water table. IMAGE
