US 2024/0052743 A1 · AUTOMATED METHOD AND PROCESSING TRAIN FOR LINING TUNNELS

Abstract

A processing train configured to run along a tunnel to lay a solidifiable fluid material on a wall of the tunnel and allow the solidifiable fluid material to solidify for construction of a lining of the tunnel, an advancement system for advancing the sliding form, a closing edge for closing a space between a front edge of the sliding form and the wall of the tunnel, and spouts for dispensing the solidifiable fluid material around a front segment of the sliding form. A method for constructing a lining of a tunnel with the solidifiable fluid material involves, defining an interspace between the front segment of the sliding form and the wall of the tunnel, introducing the solidifiable fluid material into the interspace and, after hardening time, advancing the sliding form to form a new interspace and successive lining sections.

Dependent claims

A processing train configured to run along a tunnel so as to lay a solidifiable fluid material on a wall of the tunnel and allow the solidifiable fluid material to solidify for construction of a lining of the tunnel, the processing train comprising:

a sliding form with a lateral shape of a desired lining on the wall of the tunnel;
an advancement system suitable for advancement of the sliding form stepwise along the tunnel;
a closing edge adapted to close, radially with respect to the tunnel, a space between a front edge of the sliding form and the wall of the tunnel;
and
spouts for dispensing the solidifiable fluid material around a radially external front segment of the sliding form.

2 more elements

A method for constructing a lining of a tunnel with a solidifiable fluid material, by a processing train which is advanced stepwise along an axis of the tunnel, the method comprising:

a) using a sliding form in the processing train, having a lateral shape of a desired lining on a wall of the tunnel and extending over a section of the tunnel, so as to define an interspace between a front segment of the sliding form and the wall of the tunnel, the interspace being closed at the front by a closing edge which extends radially with respect to the axis of the tunnel between the sliding form and the wall of the tunnel;
b) introducing the solidifiable fluid material into said interspace;
c) waiting for a given solidification time;
d) advancing the sliding form by one step inside the tunnel so as to form a new interspace situated between the front segment of the sliding form and the wall of the tunnel and bordering at the rear with the solidifiable fluid material introduced into a preceding interspace;
and
e) repeating steps b) to d) to create successive lining sections of the tunnel.
