Abstract

The invention discloses a floating slab rail unit. The floating slab rail unit comprises a floating unit slab and a plurality of intelligent vibration isolators used for carrying out floating supporting on the floating unit slab in the vertical direction. Each floating unit plate comprises a plurality of floating plate unit blocks and a connecting assembly, the floating plate unit blocks are sequentially arranged in the extending direction of the rail line and connected in a spliced mode, each floating plate unit block is provided with a plurality of mounting preformed holes used for installing the intelligent vibration isolators, and the connecting assemblies are used for connecting the floating plate unit blocks to form the floating unit plates. The intelligent vibration isolator comprises an inner cylinder assembly and an outer cylinder assembly which are arranged in an inner-outer sleeving mode in the vertical direction. The upper end of the outer cylinder assembly is arranged in acorrespondingly arranged mounting preformed hole; the inner cylinder assembly is sleeved with the outer cylinder assembly, the lower end of the inner cylinder assembly extends out of the lower end ofthe outer cylinder assembly and then is connected with the rail foundation, and the inner cylinder assembly is used for providing elastic supporting force for telescopic arrangement of the outer cylinder assembly in the vertical direction so that the outer cylinder assembly can conduct floating supporting on the floating unit plate in the vertical direction.

Description

technical field [0001] The present invention relates to the field of rail transportation, in particular, to a floating slab rail unit. Background technique [0002] Floating slab track bed is currently the most effective structure to reduce vibration and noise of rail transit. Compared with other vibration-damping tracks, it has significant advantages such as good vibration-damping effect, low operation and maintenance costs in the later stage, and long service life. The existing floating slab track bed is formed by connecting multiple sections of floating slab track units in sequence along the extending direction of the track line, and the floating slab track unit includes a floating cell board, and is connected with the floating cell board for performing the operation on the floating cell board. Floating supported elastic support structure. [0003] Existing floating unit slabs generally adopt the construction method of cast-in-place or prefabricated installation. However...
