Performance.
Chinese patent literature CN105463948B discloses a kind of concrete filled steel tube sleeper suitable for non-fragment orbit, uses steel
Connecting component of the pipe concrete as sleeper block, compared with the connection of general Combined type reinforced truss, globality is stronger, can be effective
Alleviate deformation of concrete sleeper durings storage, transport etc.；Pass through concrete filled steel tube and the one of sleeper concrete block simultaneously
It is body formed, i.e., while pouring sleeper concrete block realize concrete filled steel tube forming, and by concrete filled steel tube be designed to by
More hollow steel pipe compositions, are effectively increased sleeper track geometry holding capacity, reduce amount of reinforcement, improving can construct
Property, it can directly construct at the scene, meet the requirement of sleeper bending-twisting ability.
However, further study showed that, above-mentioned sleeper still remains following problems:
Concrete filled steel tube is formed after pouring concrete within steel pipe, concrete filled steel tube surface is relatively smooth steel face,
After the materials such as direct Transducers Embedded in Concrete, reclaimed rubber, resin material, the bond stress being in contact with it is limited；With two outer diameter 40mm
Steel pipe insertion 200mm depth concrete sleeper block in for, the bond stress that is formed between concrete is 2.5t, and steel pipe is mixed
There are also to be strengthened for connection between solidifying soil and sleeper block.
Prefabricated double-block type concrete filled steel tube sleeper is tied up, is lifted and heap is left with during being transported to construction site
In difficulty.
After prefabricated concrete sleeper is transported to railway line construction site, during the cast in situs of road bed board, sleeper
The railway roadbed board concrete that the inlet part of block is poured with after connect not secured enough, and there are endurance issues, meetings between New-old concrete
The diseases such as crack, these all could be improved raising.

8. such as the groove type connection reinforcing structure between the described in any item sleeper blocks of claim 4-5 and railway roadbed, feature exists
In:
Further include such groove, is vertically extended on the side wall of in-orbit bolster.
9. the groove type connection reinforcing structure between sleeper block as claimed in claim 8 and railway roadbed, it is characterised in that:
Up and down direction extend the groove, from top to bottom, depth of groove of the groove on the cross section of the sleeper block (1) by
It is cumulative big；
Alternatively, the groove that up and down direction extends, from top to bottom, groove of the groove on the cross section of the sleeper block (1)
Depth, becoming larger-becoming smaller-recurrent fluctuations to become larger, so that the bottom surface of groove is wavy；
Alternatively, the groove is other than the projection on track cross section has vertical altitude component, throwing in the horizontal plane
Shadow also has the horizontal length component of track transverse direction；
Alternatively, the groove successively interval setting in the transverse direction of track that multiple up and down directions extend, and it is horizontal from track
To middle part on lateral outer side direction, the length for the groove that multiple up and down directions extend highly is sequentially reduced vertically；
Alternatively, the groove that multiple up and down directions extend successively is spaced setting, multiple upper and lowers in the transverse direction of track
To the i.e. vertical height of length of the groove of extension, becoming larger the changing of the relative positions repeatedly that-becoming smaller-become larger.
10. the groove type connection reinforcing structure between sleeper block as claimed in claim 4 and railway roadbed, it is characterised in that:
The same lateral sidewalls include the groove of multiple perforations, in arranged in parallel up and down.
11. the groove type connection reinforcing structure between sleeper block as claimed in claim 5 and railway roadbed, it is characterised in that:
The same lateral sidewalls include the spaced groove of multiple groups, are in arranged in parallel up and down between every group, and flat up and down
The spaced groove of capable multiple groups, from top to bottom, the spacing between every group of further groove is gradually reduced.
12. the groove type connection reinforcing structure between sleeper block as claimed in claim 8 and railway roadbed, it is characterised in that: groove
Lower end run through sleeper block bottom surface.
