The invention relates to a sleeper damping,
derailment-preventing and segment-damage-preventing device for a shield underground transportation
system, and belongs to the technical field of shield equipment. Profile steel is arranged to serve as a sleeper, steel rails matched with a transport vehicle serves as rails, and the steel rails and the sleeper are connected in a pressing plate mode and fastened through bolts. According to the invention, the contact surface of the sleepers and a shield segment is designed into an arc with the same
radius as the inner side structure of the segment, the profile steel serving as the sleeper is designed into a groove type, a rail determinator is cancelled, and damping rubber plates are additionally arranged among the sleeper, the shield segment and thesteel rails, the damping rubber plates and the sleeper are fixed through bolts, so that during shield construction, vibration and
noise generated by the underground transportation
system are effectively reduced and controlled, the segment is protected, the
derailment phenomenon caused by the fact that wheels dynamically
impact the steel rails to vibrate is reduced, the track mounting effect is improved, manpower,
material resources and financial resources are saved, and the construction progress is accelerated.
