Furthermore, the installation sleeve and the adjusting sleeve are both nylon sleeves.
Still further, the two mounting sleeves are distributed on any group of opposite angles of a sleeper groove of the ballastless track.
Further, the waterproof coating is provided with a slope.
Furthermore, the lower part of the long bolt is provided with a pre-embedded sleeve coarse thread matched with the installation sleeve, and the upper part of the long bolt is provided with a fastener fine thread matched with the first bolt hole and the second bolt hole.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses to the condition that ballastless track large-scale settlement section fastener can't satisfy the track height adjustment volume, adopt adjustable elastic sleeper can be convenient realize the adjustment of track height by a wide margin, the adjustment range can reach 50 ~ 100mm, cooperate the fastener adjustment can satisfy ballastless track large-scale settlement section track height adjustment problem; the utility model discloses can realize increasing the problem of sleeper elasticity simultaneously, solve the problem that original ballastless track is provided elasticity by the fastener entirely, further increase the track damping performance, all be favorable to structure life, riding comfort; meanwhile, the problem that the conventional ballastless track sleeper is damaged, replaced and maintained difficultly is solved.
