Embodiment Construction
[0017] combined with figure 1 , 2 , 3, 4, 5 describe an embodiment of the present invention.
[0018] An urban rail transit vibration-damping turnout structure, comprising a basic rail 1, a point rail 2 and a guide rail 3, the basic rail 1, the point rail 2 and the guide rail 3 are all installed on the track bed through a vibration-damping fastener system 4; The heel end of the rail 2 has an elastic bendable section 16, and the width of the rail limb on the working side side of the elastic bendable section 16 is smaller than the width of the rail limb on the working side side of the other sections of the tip rail 2, that is, the working side of the elastic bendable section 16. 15-50mm is cut off on one side of the rail limb; the joints of the basic rail 1, the tip rail 2 and the guide rail 3 are connected by the vibration-damping joint splint 17 and the common joint splint 18, and the vibration-damping joint splint 17 is installed on the non-working side On one side, the com...
