Description

Floating slab unit track

Technical Field

The invention relates to the field of rail transit, in particular to a floating plate unit rail.

Background

The floating slab track bed is the most effective structure for reducing the vibration and noise of the rail transit at present, and has the remarkable advantages of good vibration reduction effect, low later-stage operation and maintenance cost, long service life and the like compared with other vibration reduction rails. The existing floating slab track bed is formed by sequentially connecting a plurality of sections of floating slab unit tracks along the extension direction of a track line, and each floating slab unit track comprises a floating unit slab and an elastic supporting structure which is connected with the floating unit slab and is used for carrying out floating support on the floating unit slab.

The existing floating unit plate generally adopts a construction mode of cast-in-place or prefabricated installation, but the cast-in-place floating unit plate has complex structure, the quality of cast-in-place construction is not easy to guarantee, and the problems of poor appearance, exposed reinforcing steel bars, surface cracking, large deviation of geometric dimension precision of a track and the like are easy to occur. Although the common prefabricated floating unit plate is suitable for mass production in factories and has high construction speed, the section of a tunnel construction site is small and is limited by construction space and transportation and hoisting, the length of a single block of the common prefabricated floating unit plate is generally 3.6-8 m and cannot reach 25-30 m of a cast-in-place floating unit plate, and the vibration reduction effect of the common prefabricated floating unit plate is reduced due to the shorter length and the smaller mass. Due to the limitation of the length of the plate body, the floating plate unit track formed by common prefabricated floating unit plates is inevitably in a discontinuous condition at the plate ends of the adjacent floating plates, the discontinuous condition is more, the vibration response generated when a train passes through the plate ends of the floating unit plates is much larger than that generated when the train passes through the plates, the driving safety is reduced, and the service life is reduced due to the poor stress condition of the track part at the plate ends; although the shear hinges are adopted to connect adjacent common prefabricated floating unit plates in the actual engineering, the problem of influencing the stable structure and safe use of the unit track of the floating plate caused by the discontinuity of the plate ends still cannot be effectively solved.

On the other hand, the vibration phenomenon exists at every moment in rail transit, and for a floating system of a floating plate unit track, vehicle-induced vibration is more obvious on the system, and the vibration is necessarily accompanied with the generation of energy.
