Abstract
The utility model is related to a kind of urban track traffic concrete wide crosstie, including wide pillow body, long 0.54m, wide 2.2m, high 0.18 ~ 0.2m；Width pillow body interior is provided with transversely prestressed bars and longitudinal structure reinforcing bar；A pair of tracks are disposed with wide pillow body.The utility model be prevented effectively from urban track traffic underground cable Ballast track section because of railway roadbed surface it is discontinuous caused by Daily Round Check, in emergency circumstances passenger's escape is difficult the shortcomings of while, ballast track bed section fastener can be made to be consistent with the interval fastener type that usually section is used in underground, be conducive to production and operation maintenance etc..
Description
Technical field
The utility model is related to track engineering technical field, and in particular to a kind of urban track traffic concrete wide crosstie.
Background technology
Urban track traffic underground cable typically uses ballastless track bed, but because ballastless track bed later stage adjustment amount is small, in underground
When line passes through the unfavorable geology region such as ground fissure, active fault, for the ease of using Ballast track the adjustment after foundation deformation more
Structure.At present, existing underground cable ballast track bed is generally using new II type concrete crosstie or III type pillow concrete crosstie, and railway roadbed surface is not
Continuously, it is unfavorable for Daily Round Check and in emergency circumstances passenger evacuates.And the wide pillow of state's iron aggregate concrete is used, there is fastener type obstructed
With, be unfavorable for production and operation maintenance.
The content of the invention
The purpose of this utility model is to provide a kind of urban track traffic concrete wide crosstie, and overcoming underground cable to use has the tiny fragments of stone, coal, etc.
During track structure, existing sleeper influence Daily Round Check and in emergency circumstances passenger's evacuation, and the wide pillow fastener class of state's iron aggregate concrete
Type is not general, influences the problems such as production and operation maintenance.
The technical scheme that the utility model is used for：
A kind of urban track traffic concrete wide crosstie, it is characterised in that：
Including width pillow body, long 0.54m, wide 2.2m, high 0.18 ~ 0.2m；
Width pillow body interior is provided with transversely prestressed bars and longitudinal structure reinforcing bar；
A pair of tracks are disposed with wide pillow body.
Wide pillow body interior be provided with above and below two layers of transversely prestressed bars, arrange what is annularly closed outside transversely prestressed bars
Longitudinal structure reinforcing bar.
Transversely prestressed bars end is provided with anchor plate, and the outline of anchor plate is octagon.
Width pillow body both lateral sides end face is preset with lifting sleeve, and both sides symmetrically respectively set two.
The utility model has advantages below：
The utility model is being prevented effectively from urban track traffic underground cable Ballast track section because railway roadbed surface is discontinuous
While the shortcomings of caused Daily Round Check, in emergency circumstances passenger escape difficult, ballast track bed section fastener and underground can be made
The fastener type that interval general location is used is consistent, and is conducive to production and operation maintenance etc..

Embodiment
The utility model is described in detail with reference to embodiment.
A kind of urban track traffic concrete wide crosstie that the utility model is related to, it is adaptable to urban track traffic subterranean region
Between use ballast track bed track engineering, including it is wide pillow body 1, long 0.54m, wide 2.2m, high 0.18 ~ 0.2m.Every piece wide pillow is originally
A pair of tracks 2 are disposed with body 1.Track 2 is higher by the wide pillow top surface 30mm of body 1, and nail is away from can connecing according to fastener used
Pig's tongue part is determined.
It is wide pillow body 1 be internally provided with above and below two layers of transversely prestressed bars 4, transversely prestressed bars for eliminate stress wire,
Using pre-tensioning system system, two layers of laying above and below point.Transversely prestressed bars 4 arrange the longitudinal structure reinforcing bar 5 annularly closed outside.It is horizontal
The end of presstressed reinforcing steel 4 is provided with anchor plate 6, to reduce transmission length of prestress, the outline of anchor plate 6 is octagon,
Anchor plate 6 can be fastened on compressor wire by spanner.
The wide pillow both lateral sides end face of body 1 is preset with lifting sleeve 3, and both sides symmetrically respectively set two, for lifting.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
