摘要

Method for controlled compaction of an annular passage when using tunnel-driving machines in solid rock and water-tight tubbing comprises continuously determining the excavated profile in the region of the mantle to calculate the hollow volume outside the tubbing and inserting pressed material into the profile. Preferred Features: The annular passage is temporarily sealed up to the cutting wheel by an auxiliary material.
