Method to maintain alignment of sleepers or whole rail grids while binding material sets; involves fixing rigid supports to sleeper with quick-setting composition to support sleeper on hard subsoil

摘要

The method involves connecting rigid supports (3) to the sleeper (1) with a quick-setting composition. The supports support the sleeper on the hard subsoil (6) while the surrounding concrete is not yet hard. The rigid supports are inserted in passages 92) in the sleepers until they hit the subsoil. The passages are at least partly filled with quick-setting composition.
