Abstract
The utility model discloses a supporting structure of a railway track, which can prolong the service life of steel rails and comprises two adjacent steel rails located on the same row of steel rail. The supporting structure further comprises a backing plate arranged below the two steel rails, the two adjacent ends on the two steel rails are supported by the same backing plate, and the backing plate is fixed on a track bed by a fixing device. The two adjacent ends of the two steel rails are supported by the backing plate, namely the joint position between the two steel rails is supported by the backing plate; therefore, when a motor vehicle passes by the joint position, though the end parts of the steel rails bear rather large impact forces, the downward bending trend of the end parts of the steel rails is restrained due to that the below parts of the steel rails are supported by the backing plate, so as to obviously reduce the deformation quantity of the end parts of the steel rails and restrain the up-down interlacing degree of the adjacent steel rails, thereby not only restraining further increasing of the impact forces that the steel rails bear, but also being beneficial for prolonging the service life of the steel rails.
