摘要：
The method relates to the laying of rails in a trench into which concrete is subsequently poured in order to fasten the rails. The method consists in laying adjustable-length ties (4) on the bottom of the trench (3), in roughly positioning the rails (14, 15) by means of block-supports, in fastening the ties to the rails by using tie-screws (10) and anchor sleeves (11) as bolts and nuts, in adjusting the length of the ties and in leveling the ties by means of auxiliary screws (18), and then in pouring the concrete, the auxiliary screws being subsequently removed. The ties are preferably pre-equipped with tie-screws, with sleeves and with rail-fastening clamps and the tie-screws and the sleeves may also be used for fastening tie-plates to the ties.
