Embodiment Construction

[0051] The following will combine Figure 1-14 Specific embodiments of the present invention are further described in detail.

[0052] figure 1 According to a specific example of the present invention, it can be seen from the cross-sectional view of the single ballast brick 1 that it includes an elastic fixing sleeve 1A that can be transformed from waste vehicle tires, a set of distance maintaining pads 1B, a tensioning device 1C, Side wall reinforcement plate 1D, insulation plate 1E, elastic perforated bottom bracket 1P and locking unit 1Q.

[0053] Depend on figure 1 , figure 2As shown, through the additional distance maintaining pad 1B and tensioning device 1C, the tire can be changed from a circular shape to an elastic fixing sleeve 1A approaching a strip rectangle. The side wall reinforcement plate 1D helps the elastic fixing sleeve 1A to further maintain the desired shape. It needs to be stated that the present invention covers other elastic fixing sleeves of other...

Abstract

The invention provides a ballasted railway ballast bed reinforcing device, system and method and relates to the field of construction of railway infrastructures. A device with an elastic fixed sleeve comprises at least one elastic fixed sleeve which is formed by surrounding a columnar space by at least one elastic continuous side wall, and at least one locking system for controlling the shape of each side wall; the locking system is connected with at least two points on each side wall so that the side wall keeps a certain shape; each columnar space is internally filled with interior decoration materials; the interior decoration materials have the compressive strength higher than that of side wall materials. By the aid of the device with the elastic fixed sleeve, the good elasticity of a tire rubber layer and the vertical high compressive strength of crushed stone particle layers can be combined very well, and the device has excellent performances when being applied to the construction of the railway infrastructures.

Description

technical field [0001] The present invention relates to the field of railway infrastructure construction, and more specifically, to a device, system and method for building and reinforcing a ballasted railway track bed. Background technique [0002] Ballasted railway tracks are adopted by most railway companies in the world because of their small construction investment and convenient track adjustment and maintenance. [0003] The ballasted track is composed of steel rails, sleepers, ballast bed, turnouts and couplings. The ballast ballast bed with generally trapezoidal cross-section evenly distributes the load on the sleeper to the subgrade surface, and provides uniform elasticity and cushioning to reduce the impact and vibration of the wheel and rail. It helps to fix the sleeper position, drain water and adjust the sleeper position by tamping. [0004] The modern ballast bed is mostly made of crushed stone after screening and grading. In order to provide sufficient late...
