Abstract (en)
[origin: EP0803609A2] The method for the precision placing of rail saddles (1) in concrete involves pouring a concrete slab (31) having a solid consistency and smooth surface. Whilst the concrete is fresh the saddle is driven in whilst vibrating with a vibrator (35) until the saddle attains the required position. A steel sheet base (30), laid on the concrete, has a circular opening on which a vertical tube (28) is welded. A polyurethane receptacle (28) passed through the tube has an internal surface fitting the shape of the saddle. During vibration the liquefied concrete is prevented from rising up the tube by the sheet and receptacle and forced into the insert cavities.
