IN REPAIR WORKS IN A LONG DIMENSIONAL BEAMLESS RAIL-SLEEPER FRAME RESEARCH OF TENSION AND DEFORMATIONS

Abstract

In the article, the consequences of the residual deformation caused by the force formed in that part of the road due to the tension caused by the need to lift it or the need for heavy road vehicles to climb on it while carrying out repair work on the substructure of the long-range rail-sleeper frame and the measures to eliminate them are discussed. longitudinal residual displacement has a negative effect on all elements of the upper part of the road, reducing their service life. Experiences show that by properly strengthening the gravel ballast layer under the sleepers, by properly tightening the anchoring or clamping bolts, there are good conditions for the rail-sleeper frame not to be exposed to negative effects for a long time. can be created. After the repair, the additional force that may arise due to the residual displacement along the length of the rails can be calculated, and a forecast can be made so that this problem does not occur. displacements and bending should not occur. By strengthening the ballast prism with special machines and properly fixing the rails, it is possible to fully stabilize the position of the rail-sleeper frame in the longitudinal direction.
