Embodiment Construction
[0018] The present invention will be further explained below in conjunction with the drawings.
[0019] Such as Figure 1-3 Shown: a relatively movable track-track bed combination system, which structure includes a basic track 2, a telescopic track 7, a telescopic track support device 9 and a lap type track bed 1, the basic track 2 through the basic rail gusset assembly 3Fixed on the lapped track bed 1, disconnected at the vertical separation seam 10 and replaced with a telescopic rail 7; the length of the telescopic rail 7 is slightly larger than the width of the vertical separation seam 10 and is partially placed in the hollow rail, Instead of the basic track, the telescopic track 7 is located on the steel backing plate 8 and connected horizontally with the pressure spring 5; the telescopic track support device 9 is located in the vertical isolation seam 10, and the right side is connected to the overlapping track bed through the horizontal guide rod 11 1 is connected; the hor...

The invention discloses a track-ballast bed combined system capable of moving relatively, wherein the track-ballast bed combined system is used in cooperation with a shock insulation railway station house. The track-ballast bed combined system is composed of three parts including a telescopic track, a telescopic track supporting device and a lap joint type ballast bed. The telescopic track can stretch out and draw back when an earthquake occurs, and has the advantages that the movement of a shock insulation layer is not affected, and train derailment cannot be caused; the telescopic track supporting device is arranged in a vertical isolation joint and plays a role in supporting a rail spanning the vertical isolation joint; the lap joint type ballast bed can move relatively without affecting normal use of the lap joint type ballast bed. The track-ballast bed system can solve the problem that a track and a ballast bed cannot move relatively when an earthquake occurs in a traditional track-ballast bed system, enable an upper structure of a shock insulation layer to move freely, has the advantages of being simple in structure and convenient to maintain and repair, and is particularly suitable for building structures with tracks and shock insulation requirements, such as subway stations and railway stations.
Description
Technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a relatively movable rail-track-bed combination system used in conjunction with seismic isolation railway station buildings. Background technique [0002] Seismic isolation technology is a kind of passive control technology. Generally, an isolation layer is set in the building structure, and the building structure is divided into three parts: the lower structure, the isolation layer and the upper structure. When an earthquake occurs, the seismic energy is transferred from the lower structure to the upper structure and passes through the seismic isolation layer. The seismic energy is absorbed through the deformation of the seismic isolation layer, and the seismic effect of the upper structure and the deformation of the seismic isolation part are controlled, thereby greatly reducing the impact of the earthquake. The influence of the superstructure makes the superstructure only pr...
