It requires stable slide rail foundation, high straightness alignment datum line and smooth rail as basic conditions, so the flatness and straightness accuracy requirements for the rail are very high: the flatness error of a reference section of every 60m in the plane direction is less than or equal to 2mm, the straight error of a reference section of every 60m in the elevation flatness is less than or equal to 2mm, the single-point distance of the inner side surfaces of the left track and the right track of the same mileage section is required to reach 1435mm +/-0.2 mm, the height error of the double tracks is less than or equal to 0.2mm, the straightness of the top surface and the two side surfaces of the track is 0.1mm, and the torsion is not more than 0.05 mm.

The vertical anchoring bolt and the horizontal adjusting base are used as a connecting piece between the track and a slide rail foundation, namely a bearing rail beam, and the positioning precision of the vertical anchoring bolt and the horizontal adjusting base can only meet the requirements of front and back (longitudinal) ± 3mm, left and right (horizontal) ± 1mm, and height of +/-2 mm, so that the high smoothness of the track can be ensured. In the design scheme, one set of connecting piece comprises four vertical anchor bolts and a horizontal adjusting base, wherein the vertical anchor bolts are anchored by special FIS V360S anchor glue, and the horizontal adjusting base and the preformed hole are filled with high-strength M50 cement paste. There are two methods for achieving the attachment of the connector: firstly, inserting four vertical anchoring bolts into a reserved hole of a rail bearing beam one by one, injecting glue for anchoring, then installing a horizontal adjusting base, and injecting high-strength M50 cement paste; and secondly, assembling four vertical anchoring bolts and a horizontal adjusting base into a whole, installing the whole into a preformed hole of the rail bearing beam, adjusting the position, pouring anchoring glue, and finally pouring high-strength M50 cement paste. The length of the high-speed slide rail is usually more than 1km, thousands of sets of rail connecting pieces are needed, the mounting quantity is large, and obviously, the second method is high in mounting speed and more beneficial to industrial construction.
