Bottom elastic insert is provided between body bottom wall, side elastic insert is provided between short bolster and the groove body two side of installation groove,
Short bolster bottom surface offers multiple plug-in openings, it is described divide pillow be internally provided with more tops stretch out divide pillow top surface and with inserting
Hole corresponds to the spacer bar of inserting.
As further program of the utility model：Described point of pillow bottom surface is provided with elastic basic unit, elastic basic unit bottom surface
It is provided with anti-skid structure.
As further program of the utility model：The anti-skid structure be distributed in elastic basic unit bottom surface polyline shaped it is convex
Go out portion.
As further program of the utility model：Distribution is provided with multiple reinforcing bars along its length inside described point of pillow
Framework, reinforcing bar framework surrounding is respectively with connecting the corresponding position banding fixed of reinforcing bar.
As further program of the utility model：The reinforcing bar framework is the rectangle frame formed by reinforcing bar bending overlap joint
Body, pentagon framework or hexagon framework.
As further program of the utility model：Corresponding position of the spacer bar with connecting reinforcing bar inside described point of pillow
Put banding fixed.
Compared with prior art, the beneficial effects of the utility model are：The two points of pillows that are divided into of traditional pillow are formed,
By being internally provided with more connection bar connectings between two points of pillows so that the integral rigidity of pillow is reduced, even if
There is differential settlement in part way, and a point pillow will not be caused rupture failure occur, improves the service life of sleeper；Divide pillow
Body bottom surface is provided with elastic basic unit, is provided with bottom elastic insert between short bolster and the groove body bottom wall of installation groove, short bolster with
Side elastic insert is provided between the groove body two side of installation groove, passes through elastic basic unit, bottom elastic insert and side cushion
The cooperation of layer can effectively reduce the vibration noise of track operation；Entire elastic sleeper has certain elastic deformation, Neng Goushi
For the softer location of soil property, economic feasibility is good, more with exploitativeness.
