Continuous rail unloading construction process for hectometer fixed-length rail

The invention discloses a continuous rail unloading construction technology for a hectometer fixed-length rail. The continuous rail unloading construction technology comprises the following steps that firstly, a rail unloading starting point is determined; 2, determining a train parking position; 3, the multiple pairs of steel rails are unlocked; 4, the first pair of steel rails are pried up and placed on the rollers on the cross beams; 5, the first ends are fixed, and the first pair of steel rails slide into the guide frame; 6, the pushing vehicle pushes the first pair of steel rails until the first end is located at the rail unloading starting point; 7, the first end is fixed to the rail unloading starting point; 8, the first pair of steel rails are placed at the designated rail unloading position; 9, the next pair of steel rails continues to be unloaded in sequence according to the steps 4-8 till the steel rails on the layer are unloaded; and 10, the next layer of steel rails continues to be unloaded accor
