Abstract
The present invention relates to a process and to a system for laying tracks for ballastless railway and tramway lines, both in tunnel and in surface.
Claims31
A prefabricated slab for implementing layouts of ballastless railway and tramway lines, with substantially rectangular shape, with a longitudinal direction (L) corresponding to the direction (B) of laying tracks, and a transverse direction (T) orthogonal thereto, made of prestressed concrete both in the longitudinal direction (L) and in the transverse direction (T) by means of a primary reinforcement implemented with post-tensioned, sheathed wires, anchored at respective threaded ends (P) by means of metal plates and locking nuts,
- said slab further comprising a loose reinforcement, consisting of bars arranged to form a mesh embedded in cement,
- said slab having a thickness varying, depending upon the longitudinal and transverse sections, between about 200 mm and about 240 mm.
A system for laying tracks for ballastless railway and tramway lines on prefabricated slabs, comprising:
- a train for launching the slabs, equipped with handling portal and wagon for end-on launching the slabs;
- and
- a concreting train equipped for the production of concrete and for casting an intermediate or foundation layer, supporting the slabs.
