<p>Supporting device for tracks 2, which supports the tracks when structural elements 3 are being pressed through under the tracks 2 and has for this purpose a number of push-in girders 1, which are pushed through under the tracks to be supported, transversely in relation to them, and for their part are supported in the course of pressing through on the structural elements 3 to be pressed through. The push-in girders 1 rest in an individually movable manner on the upper side of the structural element to be pressed through and are pivotably connected to a strut 8, which runs transversely in relation to the push-in girders and for its part is anchored to prevent displacement transversely in relation to the direction of the track. The strut 8 is preferably braced at fixed anchoring points 10 to prevent displacement in transversely in relation to the direction of the track. <IMAGE></p> |
