1.The placement of the sleeper: the sleepers should be placed horizontally on the head of the bridge or the precast girder. The distance between the two sleepers is about half meters, and the sleepers should be horizontal, forming a straight line and paralleling with the bridge pier.
2.The placement of the sliding rail: each segment of the sliding rail should be placed on the sleepers with the mobile crane or other lifting equipment.
3.Ultra flat: the sliding rail should be flatted with the level gauge.
4.The support: If there is any gap or unfirm place, then it should be fitted firmly with the steel panel.

(2)The sleepers under the sliding rail must be firm to avoid that the rail rolls over and injures people.
