The utility model discloses a fixed a plurality of connecting pieces in light rail body length direction's both sides interval can strengthen the adhesive property of new and old concrete faying face between sleeper body and the cast-in-place railway roadbed, improves the joint strength of light sleeper body and cast-in-place railway roadbed.
Description
Technical Field
The utility model relates to a track engineering technical field, in particular to ballastless track buries formula sleeper.
Background
The ballastless track structure has the advantages of high smoothness, strong structural durability, less maintenance workload, low maintenance cost, long track structure stability, continuity, long service life and the like.
At present, two structures, namely a double-block ballastless track and a long-sleeper embedded ballastless track, are generally paved in most countries, but when a cast-in-place railway bed is embedded in a sleeper, the bonding surfaces of new and old concrete are easy to be damaged by separation, looseness, cracking and the like of a light sleeper.
Therefore, how to design a novel embedded light sleeper, the bonding performance of the old and new concrete faying surface between the reinforced sleeper body and the cast-in-situ track bed, and the improvement of the connection strength of the light sleeper body and the cast-in-situ track bed are problems that the technical personnel in the field need to solve urgently.
SUMMERY OF THE UTILITY MODEL
The utility model provides a ballastless track buries formula sleeper solves current ballastless track and lays the back, and the bonding surface crack is great between light pillow and the railway roadbed, the lower technical problem of joint strength.
The utility model provides an above-mentioned technical problem's technical scheme as follows, a ballastless track buries formula sleeper, include: a light pillow body and a plurality of connecting pieces,
the light pillow body is of a cuboid structure; the connecting pieces are fixed on two opposite sides of the light pillow body in the length direction at intervals.
The beneficial effects of the utility model are that: through fixing a plurality of connecting pieces at intervals on both sides of the light rail body in the length direction, the bonding performance of a new and old concrete bonding surface between the sleeper body and a cast-in-place track bed can be enhanced, and the connection strength of the light sleeper body and the cast-in-place track bed is improved.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Furthermore, the connecting piece is connecting reinforcement, and is a plurality of connecting reinforcement all follows the width direction of light pillow body is buried at the interval in advance the inside of light pillow body, and is a plurality of connecting reinforcement all stretches out the relative both sides of light pillow body length direction.
Furthermore, the diameter of the connecting steel bars is 6-50mm, and the extending length of the connecting steel bars is 50-250mm.
Furthermore, the connecting piece is an anchoring body, the cross section of the anchoring body is triangular, rectangular or trapezoidal, and a plurality of anchoring bodies are integrally formed on two opposite sides of the light pillow body in the length direction.
Further, the length of the plurality of anchoring bodies extending out of the light pillow body is 50-250mm.
Further, still include a plurality of prestressed reinforcement, it is a plurality of prestressed reinforcement all follows the length direction of light pillow body is pre-buried the inside of light pillow body, and is a plurality of prestressed reinforcement all stretches out light pillow body length direction's both ends.
Furthermore, the length of the prestressed reinforcements extending out of the light pillow body is 50-250mm.
The adoption of the further beneficial effects is as follows: through fixing many prestressing steel in the inside of light pillow body and stretching out light pillow body length direction's both ends, can improve the structural strength of light pillow body on the one hand, on the other hand can strengthen the new and old concrete faying face adhesive property between sleeper body and the cast-in-place railway roadbed, improves the joint strength of light pillow body and cast-in-place railway roadbed.
