A method for filling cavities outside of the width of the tunnel tube of a mechanically placed tunnel

摘要

In the opening of mining tunnel in the shield driving and the tubing, the advanced of the shield between the rock and the tunnel lining resulting annular gap filled, usually with a hardening material is pressed.It is proposed according to the invention for filling or pressing of cavities outside of the width of the tunnel tube and the outcropping soil material and dissolved at the local front wall during the degradation to use the soil mixture, preferably directly, i.e, without that it has left the tunnel tube. As a result, in particular transport capacity are saved, and can be used both for the removal of the degraded bottom as well as for the delivery of from outside the tunnel tube of the coated material.
