Abstract
An adjustable device for railway to cross active faults is provided to fix a rail and a sleeper, including: a fastener mounting base, disposed between the rail and sleeper; clamping pipes, disposed between the fastener mounting base and the sleeper, the sleeper is provided with a through groove, and the clamping pipes are detachably fixed inside the through groove; control parts, disposed on an inner wall of the clamping pipes, each of the control parts is configured to detect lateral pressures between the fastener mounting base and corresponding one of the clamping pipes, thereby to separate the corresponding one of the clamping pipes from the through groove, the device ensures that the rail will not produce bending deformations after the lateral dislocation of the bottom layer during earthquake events, and ensure that a train or rail repair vehicle can pass at a low speed after earthquake.
