Abstract: A guideway structure for high-speed track-bound transportation composed of two or more than two girder-segments. The structure of the guideway is characteristic of: At the intermediate positions on the girder top and the girder bottom of the connecting ends of the said girder-segments are all disposed the pre-embedded steel elements and some anchoring nails used for ensuring the pre-embedded steel elements to be reliably connected with the concrete of girder-segments, after the relevant connecting ends of the two adjacent girder-segments are placed closely, they may be connected together to form a two-span quasi-continuous girder by tightening a plurality of bolts through their respective through hole on the connecting elements and on the pre-embedded elements.

Abstract: An adjustable bearing composed of top plate, top seat, ball hinge, stud, locking nut, stud seat and locking screw, the adjustable bearing of the invention can be steplessly adjusted vertically and horizontally, making the installation, replacement and adjustment more convenient, it has the special feature of low compression deformation, high precision, low cost and maintenance-free.

Abstract: A guideway structure for the high-speed track-bound transportation is composed of the lower-layer main load-bearing girders and the guideway-surface structure elements. The structural elements are connected by the steel elements at the functional zones and the reinforced concrete plates on the guideway body to form an integral. The invention is one of the guideway structures especially suitable for the guideway structure across a river of medium- or small-width.
