The present disclosure relates to a ramp kerb for supporting a transverse edge of a ramp surface and a ramp lip extension having an attachment portion. The ramp kerb comprises a first longitudinally extending channel open at an inner transverse edge of the ramp kerb for receiving a transverse edge of the ramp surface and a second longitudinally extending channel open at the inner transverse edge of the ramp kerb for receiving an attachment portion of the ramp lip extension. The first and second longitudinally extending channels are vertically spaced.

A damping valve device includes an actuator which carries out an axial displacing movement on a sliding sleeve. The sliding sleeve, along with a fixed valve carrier, forms a slide valve which has two flow directions. The slide sleeve is impinged with damping medium on a front side and on a rear side in an incident flow direction, and the front side of the slide sleeve and rear side of the slide sleeve are impinged hydraulically in parallel by damping medium during the incident flow.

The invention discloses a flanged groove type FRP (Fiber Reinforce Plastic) plate-concrete combination bridge deck. The flanged groove type FRP plate-concrete combination bridge deck comprises an FRP plate and concrete, wherein the FRP plate comprises a plurality of single groove type FRP plates; every two single groove type FRP plates are connected end to end in an alignment attachment mode of groove shape side rib plates and are spliced into the FRP plate; the concrete is poured onto the FRP plate and covers the FRP plate. The flanged groove type FRP plate-concrete combination bridge deck is simple in structure and convenient to construct, and various stress and configuration requirements on longitudinal and horizontal bridge directions can be better met.

The invention discloses a pulling-rope diverter for inclination of a rope tower. The pulling-rope diverter comprises saddle bodies and rope-strand transition pipes connected by transition flanges, wherein wire distributing pipes arranged in the saddle bodies adopt raindrop-shaped wire distributing pipes; wire-distributing-pipe positioning plates are provided with raindrop-shaped holes; rope-strand guiding sections are arranged between the two ends of the saddle bodies and the transition flanges; each rope-strand guiding section consists of a saddle-body connecting flange, a wire-distributing-pipe transition plate, a guide pipe connecting flange, a guide pipe, a wire pipe, a wire pipe positioning plate and a guide pipe transition plate; the guide pipe is internally provided with the wire pipe positioned by the wire pipe positioning plate; one end of the wire pipe is respectively inserted into a pipe hole arranged on the wire distributing pipe transition plate; the pipe hole arranged on the wire-distributing-pipe transition plate corresponds to the raindrop-shaped hole arranged on the wire-distributing-pipe positioning plate; the wire-distributing-pipe transition plate is connected between the connecting flange and the guide pipe connecting flange; the other end of the wire pipe is inserted into the pipe hole arranged on the guide pipe transition plate at the end part of the guide pipe; and the guide pipe transition plate is arranged in the transition-section flange. The pulling-rope diverter disclosed by the invention has the advantage that the saddle bodies are anchored in the rope tower by adopting a manner of oblique intersection.
