Abstract
The method is used in the repair of tramcar lines, mounted in grooves of panel sections, when, as a result of operational loads, the panels are diverted from their designed position. By the method, the operations are implemented quickly, without switching off the voltage from the overahead electrical lines, also avoiding the cutting of the rails and their diassembly, as well as the disassembly of the panels themselves. By the method holes along the length of the panel (2) are drilled in advance at some distance between each other, after which the panel is raised to its original position (4) and binding mixture is injected across holes (3). The injection continues until the binding mixture starts getting out of all holes (3), as well as in the clearances (5) around them, after which it is terminated, and panel (2) is freed and after a period of a few hours the track is ready for operation. Raising is made by means of grips (7) with lateral beams (11) supported on jacks (8). 5 claims, 2 figures
