Anchoring vertical building walls in ground with high underground water level - sinks bores from plenum over underground water level, passing through vertical building walls

摘要

Above the underground water level (2) are located the heads of the prestressed injection anchors. From a plenum (3), above the underground water level, are sunk bores (7) which pass through the vertical building walls (1) in points (8) below the water level, reaching into a region (14) behind the building wall. Into the bores are fitted tensile members, embedded into a self-hardening medium (9) after retracting the boring linkage. The medium is filled down to the passing points, where a positive grip is formed after hardening. The tensile members are inserted in relieved state.
