Method for constructing a railroad in concrete having vertical and lateral adjustment steps prior to concrete pouring

A method for constructing a railroad, according in which rails are positioned in a trench into which concrete is subsequently poured in order to fasten the rails, wherein:

• ties are made having means for adjusting their length,
• these ties are laid down on the bottom of the trench in a position corresponding approximately to the desired tie-spacing,
• the rails are laid on provisional block-supports and a rough vertical and horizontal positioning of the rails is carried out by means of these block-supports,
• the ties are lifted up and are fastened to the rails by using tie-screws and anchor sleeves respectively as bolts and nuts for holding rail-fastening parts,
• vertical leveling screws are screwed into the tie and bearing plates for the end of said screws are disposed under the screws, on the bottom of the trench,
• the rails are leveled by means of the leveling screws,
• gage-setting of the track is adjusted by the tie-length adjustment means,
• the concrete is poured into the trench so as to cover the ties, and
• the leveling screws are removed.
