Abstract

The invention discloses a split mounting type intelligent floating slab rail unit and a split mounting connection construction method. The split mounting type intelligent floating slab rail unit comprises floating unit plates and a plurality of intelligent vibration isolators. Each floating unit plate comprises a plurality of floating plate unit blocks and connecting structures, the floating plateunit blocks are sequentially arranged in the extending direction of the rail line, each floating plate unit block is provided with a plurality of mounting preformed holes, and the connecting structures are arranged between the adjacent floating plate unit blocks. The intelligent vibration isolator comprises an inner cylinder assembly and an outer cylinder assembly which are arranged in an inner-outer sleeving mode. The upper end of the outer cylinder assembly is arranged in the mounting preformed hole; the inner cylinder assembly is sleeved with the outer cylinder assembly. And the lower endof the inner cylinder assembly extends out of the lower end of the outer cylinder assembly and then is connected with a rail foundation, and the inner cylinder assembly is used for supplying elastic supporting force for telescopic arrangement of the outer cylinder assembly in the vertical direction, or the inner cylinder assembly is used for supplying elastic supporting force and hydraulic dampingforce for telescopic arrangement of the outer cylinder assembly in the vertical direction.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to an assembled intelligent floating slab track unit. In addition, the present invention also relates to a construction method for assembling and connecting track units of an assembled intelligent floating slab. Background technique [0002] The floating slab track bed is currently the most effective structure for reducing the vibration and noise of rail transit. Compared with other vibration-absorbing rails, it has significant advantages such as good vibration reduction effect, less post-operation and maintenance costs, and long service life. The existing floating slab track bed is formed by sequentially connecting multiple sections of floating slab unit tracks along the extension direction of the track line, and the floating slab unit track includes floating unit slabs and is connected with the floating unit slabs for Elastic support structure for floating support. [0003] Th...
