Urban railway curved section track panel preparing method
The invention belongs to the technical field of engineering technical urban rail transit construction, and particularly relates to an urban railway curved section track panel preparing method. The method comprises the following steps that the state of track panels of a track is restored, sleepers are laid, the stagger amount of track panel rail joints is prefabricated, the curve shortening amount is calculated, the shortening amount between any points of a transition curve is calculated, the transition curve shortening amount is calculated, the curve section total shortening amount is calculated, the stagger amount of track panel rail joints is calculated in a linear state or in a curve state, and the spacing distribution of the sleepers is calculated. Compared with the prior art, the method has the advantages that configuration data of the track panels are accurate, making and assembling of the track panels are convenient, simple and accurate, the problem that rail gaps are large after on-site assembly of the track panels is conducted is avoided, impact damage to railheads conducted by rail cars is reduced, shortened rails made by a factory are not used, the problem that rail sawing is needed in the curve is avoided, the waste of raw materials is reduced, the cost is saved, and the arrangement of the sleepers on the curve is regular, uniform, attractive and free of inclination.
