Embodiment 1
[0080] After a high-speed railway was opened to traffic, due to complex geological reasons, the crossover turnout 1 had a large uneven settlement. The maximum settlement was 60mm, which exceeded the adjustment range of the fastener 2 system of the ballastless crossover turnout 1 and affected the track smoothness. . This patented technology is used to lift and repair the unevenly settled ballastless crossing switch 1 to restore the track smoothness. Its process flow is as figure 1 The specific implementation is as follows:
[0081]1. Determine the lift range and lift amount of the ballastless crossing turnout 1, and arrange the strain gauges 5
[0082] Specifically: use a level instrument, a rail inspection trolley, etc. to detect the alignment of the ballastless crossing turnout 1, determine the lift range and amount, and connect it with the support layer 4 of the ballastless crossing switch 1 and the ballastless crossing. 3. Arrange strain gauges 5 at intervals of not more...
