METHOD AND DEVICE FOR PRODUCING A PRESSURE ANCHOR THROUGH A WALL CLOSING A FLOOR WITH PRESSURE WATER, IN PARTICULAR PILLOW WALL

摘要

In the method for making a sealed anchor in a soil area (2) bordered by an immersed wall, especially a sheet piling wall (1), an anchor chair is attached to the wall. This anchor chair is provided with a drill-pipe lock (32) having a seal (22) for the drill pipe (30) and an anchor lock (8) having an annular tube seal (14) for at least one anchor tension member (31). If the drill pipe (30) has reached its end position, at least one anchor tension member (31) is inserted into this drill pipe (30). Via a pressure-sealing channel and if need be a re-injection channel, hardenable structural material can be fed into the annular space between drill pipe (30) and anchor tension member (31) while pulling out the drill pipe (30). The re-injection channel and facultatively the pressure-sealing channel are arranged inside the periphery of the anchor tension member (31), and the annular tube seal (14) is attached to the anchor lock (8) in a spatially fixed manner.
