摘要:
The invention refers to a fish plate clamp (10) for unloading rails (1), that comprises a support element (11, 12) that comprises a first piece (11) and a second piece (12) each one located on a face of the rail (1), characterized in that: - each piece of the support element (11, 12) comprises an internal mortise (13) in the area of the web (3) of the rail (1), - a gripping element (14) of the rail (1) located in an internal mortise (13) of the support element (11, 12), where the internal mortises (13) comprise an inclined surface (15) in a manner that when the gripping element (14) moves along the length of the inclined surface (15) of the internal mortise (13) in the direction of the pull of the rail (1) the gripping element (14) latches onto the web (3) of the rail (1).

摘要:
A procedure for laying railway tracks on a trackbed on which sleepers (20) are located, that comprises at least the following steps: - a) approach of a track laying train (30) with the stretches of rail (1) to be laid in the laying area; - b) joining of the pairs of rails (1) to the consecutive rails (1) by means of tractor plates (200); - c) unloading the pairs of rails (1) from the track laying train (30) onto the bed; - d) squaring of the sleepers (20) by means of a squaring device; - e) joining of the consecutive pairs of rails (1) by means of a joint plate (100); - f) unloading of ballast in hoppers onto the bed; - g) tamping of the rails (1); - h) profiling of the ballast by means of a profiling device (400); - i) welding of the rails (1).
摘要:
A cementation pile comprises a longitudinal through-hole (1) and a plurality of through-holes (2) that extend transversely to the longitudinal hole (1) from the longitudinal through-hole (1) to the outer face of the pile, and can additionally comprise check valves arranged in the transverse holes (2) and designed such that the transverse holes (2) and the check valves allow unidirectional communication between the inside of the pile and the outside of the pile, from the longitudinal through-hole (1) to the lateral outer faces of the pile.

摘要:
The purpose of the invention is a railway track (3) sleeper (2) squaring device and the machine which carries this device. The device comprises a first and a second positioning element (1) adapted to be located between pairs of sleepers (2) and for locating at opposite ends of the sleepers (2) and parallel to the direction of the railway track (3) where these positioning elements (1) can be extended in that direction with the first and second positioning element (1) being configured such that on extending them simultaneously to a pre-set value they push the sleepers (2) so as to produce squaring of these sleepers (2).
