Reference picture 1, this is embodiments of the invention, specifically：
A kind of construction method of railway vibration insulation structure, comprises the following steps：
A) the bearing of trend box cut hole of distance Iron curb railway；
If b) laying individual wave resistance group in groove hole, if the individual wave resistance group is set along the width interval that groove is cheated, each wave resistance group
The solid wave resistance block 1 of spaced pile shape on length direction is cheated along groove including several；
C) topple over expanded and vitrified small ball 2 in groove hole or topple over the mortar concrete containing 30% expanded and vitrified small ball more than 2
Mixture.
Due to being full of space and expanded and vitrified small ball itself multi-pore structure in empty ditch, vibration wave energy in air and
Transmittance process is constantly consumed in expanded and vitrified small ball, wherein mainly high-frequency vibratory energy is largely dissipated.Afterwards, vibration wave
By continuous reflection, refraction and diffraction between wave resistance block, in this process, the low-frequency vibration wave energy of vibration wave is significantly cut
It is weak.Finally, after dissipation effect of the vibration wave energy that railway operation induces by the present invention, building is to high-speed railway operation
