Rail vibration reduction ballast bed device
The embodiment of the invention provides a rail vibration reduction ballast bed device. According to the device, multiple hole grooves are formed in the positions, a certain distance away from the outer sides of steel rails on the two sides, on a rail overall ballast bed. The hole grooves in the same side are distributed to form a hole array, and each hole array is parallel to the steel rail on the same side. Multiple second row hole grooves are formed in the outer sides which are a certain distance away from the first row hole grooves. The second row hole grooves in the same side are distributed to form a second row hole array parallel to the steel rail on the same side. Multiple single hole grooves and hole arrays are dug in the positions which are a certain distance away from the outer sides of the steel rails on the two sides of the overall ballast bed; the hole array ballast bed generates interference on incident vibration waves through the hole arrays so that the vibration waves can be reflected, scattered and diffracted, generated infrasound vibration waves and the incident vibration waves act on each other and mutually offset, and accordingly the aims of vibration reduction and noise lowering are achieved; the hole array ballast bed can adjust vibration reduction performance by changing the cross section area, the depth and/or single body distance of single bodies in the hole arrays.
