The invention relates to a retaining device (11) comprising a base (12) which also serves as a distribution plate, containing a drill hole (13), provided with wedges (15) for retaining a rod (41) of an anchoring bolt, passing therethrough. Said device is made of a plastic material reinforced with discontinuous fibres.
The invention relates to a predictive method for analysing tampering equipment (11) installable in a tampering machine that can be moved along a track. The tampering equipment (11) comprises a set of tamper picks that can be moved vertically and transversely by means of actuating elements; where measuring equipment (12) can be installed on the tampering equipment (11) in order to measure vibrations of the tampering equipment (11), caused by play between the actuating elements of the tamper picks as they perform a process of tampering the ballast bed of the track.
The invention relates to a set of construction plates (11) installed on the surface (13) of the free inner section of a tunnel (12). The construction plate (11) takes the form of a corrugated plate. The corrugated construction plate (11) can be overlapped transversely and longitudinally with other adjacent construction plates (11) in order to line the inner surface (13) of the tunnel (12) transversely and longitudinally either fully or partially, thereby sealing said inner surface (13).

Abrégé
Aqueous-base polymeric composition that comprises a terpolymer formed by at least three types of monomer and a stabilizing system that comprises anionic, non-ionic and polymeric surfactants, at least one protective colloid, at least one coalescing agent that promotes film formation, and at least one rheological agent, for soil stabilization and for controlling dust and embankment erosion. Said compositions have demonstrated good stability in terms of the polymeric dispersion which is transmitted to the element applied, with a high binding capacity, thereby generating greater compaction of the element to which it is applied, and very good resistance to atmospheric agents in terms of the polymer dispersion, the element to which it is applied retaining the properties conferred thereon by the polymeric dispersion.
The invention relates to a device for assisting with the movement of partially or entirely sightless persons; wherein the assistance device comprises a loop of parallel electric guide conductors (12) arranged along a path to be travelled by a sight-impaired person in public spaces; the loop conducts an AC current supplied by an AC emitter (11), such that a magnetic receiver (13) perceives said magnetic field and outputs an information signal based on the measured magnetic field, the information signal being adapted to the perceptive capacity of the partially or entirely sightless person wearing the magnetic receiver; and the emitter (11) can modulate the generated signal in order to transmit information to the receiver (13).
