[Prior Art]

 In order to construct a retaining wall with piles, it is necessary to constantly supply piles and materials to the pile driving site. Therefore, conventionally, materials were transported to the vicinity of the pile press-in / pull-out machine by transporting means such as trucks and cranes. However, this method has the disadvantage that the construction site is narrow, and the transportation means cannot be used in rivers, under bridges, or in places with poor scaffolding.

Therefore, a space is provided on the existing piles, a track is installed at the upper end of the pile row, and construction materials and the like are transported by a transporting means that runs along the track. In order to install this track, a pair of flat rail pedestals were set up facing each other at the upper end of the existing pile row, and the piles were clamped to fix the rail pedestals on the existing piles (actual Kaihei 3 -12901 publication).

[Problems to be solved by the device]

 However, in the above-mentioned rail pedestal, the rail pedestal is formed in the shape of a flat plate and has only one fitting groove into which the upper end of the pile fits, so even if it is fixed to the upper end of the pile. Since it lacks stability and falls down in the rail laying direction (pile row direction), there is a problem that the attachment points of the rail pedestal to the pile must be firmly fixed by separate fixing means. An object of the present invention is to provide a rail support for a rail for carrying on a pile that can be easily and securely fixed by simply fitting and mounting the rail support on the upper end of an existing pile row.
