Description
Technical field
The present invention relates to technical field of rail traffic, and in particular to a kind of novel track system across Flood gate.
Background technique
City Rail Transit System is generally underground line, and according to people's air defense code requirement, the ground positioned at rivers two sides is got off
Flood gate can be arranged in end of standing, and to prevent from making flood enter tunnel and station because unexpected, avoid large-scale casualties
And property loss, to protect subsurface equipment and personal safety.The pre-buried doorframe (material is steel) of flood gate threshold need to pass across
Track, the longitudinal width along track circuit are generally 1044mm.Doorframe top surface is concordant with rail surface, and two are reserved on doorframe
The railtrack grooves of width about 250mm, pass through for rail.
Therefore, at flood gate threshold, rail clip and sleeper need to be arranged across pre-buried doorframe, the horizontal spacing between fastener
For 1044 (doorframe width)+228 (sleeper width)=1272mm, considerably beyond main line track fastener maximum spacing 700mm's
It is required that.Such case can make steel rail displacement during car operation and vibrate excessive, the steel of rail and the pre-buried doorframe of Flood gate
Plate relative position is excessively close, to make the reflux electricity in rail that sparking phenomenon occur.In addition, steel rail displacement and vibrating excessive can also
Influence the stationarity of driving.
At present to the processing method of fastener spacing problems of too at flood gate threshold, usually at the rail bottom of threshold range
Lower plug elastomeric pad, but this method can only limit the displacement of rail vertically downwards, and it is vertically upward and horizontal can not to limit rail
To vibration and displacement, existing rail system can not fundamentally solve flood gate threshold two sides fastener spacing problems of too.
Summary of the invention
In order to overcome defect existing in the prior art, the present invention provides a kind of novel track systems across Flood gate
System, fastener spacing meets main line track operation standard at flood gate threshold, efficiently avoid because fastener spacing it is excessive caused by
Rail is unstable and sparking phenomenon.
The present invention in order to achieve the above object, the technical solution adopted is as follows:
A kind of novel track system across Flood gate, including railway roadbed block, flood door frame, sleeper, rail and fastener,
The flood door frame crosses the railway roadbed block and it is equipped with two railtrack grooves in left and right, and the sleeper is set to the flood door frame
On the railway roadbed block of two sides, the rail passes through the railtrack grooves and is erected on the sleeper, and the fastener is set in couples
In on the sleeper and fastening the rail；The side of the flood door frame is equipped with groove, is embedded in the groove described
Sleeper；The fastener includes special fastener and conventional fastener, and the special fastener is set on the railtrack grooves, the conventional fastener
On the sleeper, the spacing of the special fastener and the conventional fastener is not more than 700mm.
Further, the installation site that the rail is corresponded on the railway roadbed block is equipped with track groove, and the sleeper includes short
Sleeper, the width of the short sleeper are less than the width of the track groove and are set on the track groove, and the groove corresponds to institute
Track groove setting is stated, the sleeper being embedded in the groove is the short sleeper.
Further, flood door frame two sides are respectively provided with three pairs of short sleepers, each spacing to the short sleeper
For 600mm.
Further, the spacing of conventional fastener described in the special fastener to two sides is respectively 700mm, 650mm.
Further, the railway roadbed block includes short pillow railway roadbed block and bolster railway roadbed block, the flood door frame with it is described short
Pillow railway roadbed block pours integrally, and the bolster railway roadbed block is set to the two sides of the short pillow railway roadbed block, the short pillow railway roadbed block and institute
It states and is equipped with railway roadbed expansion joint between bolster railway roadbed block.
Further, the sleeper further includes long sleeper, and the short sleeper is set on the short pillow railway roadbed block, the long rail
Pillow is set on the bolster railway roadbed block.
Further, the two sides of the railway roadbed block are equipped with longitudinal drainage ditch.
Further, the special fastener includes spring washer, gasket, track gauge block, railway rail pad and railway spike, under the rail
Backing plate is set to below the rail, and the lower anchor of the railway spike is in the railtrack grooves, the track gauge block, the gasket and institute
It states spring washer to be successively interspersed in the railway spike top and fasten using nut, the track gauge block is L-shaped and back-off is pressed on institute
It states on rail.
Further, the gasket is L-shaped, and one side is equipped with and the matched through-hole of the railway spike.
Further, the railway rail pad two sides are symmetrically arranged with the notch for blocking the track gauge block.
The present invention compared with the existing technology, has following advantageous effects:
(1) the novel track system of the present invention across Flood gate, flood door frame side are equipped with groove, are not breaking
Under the premise of its bad overall structure and mechanical strength, sleeper is embedded in groove, so that the fastener of flood door frame two sides
Distance reduces；The special fastener being arranged on railtrack grooves breaches the technical bottleneck that conventional fastener can not be mounted on railtrack grooves, then leads to
The spacing for adjusting special fastener and conventional fastener is crossed, solves the problems, such as that fastener spacing is excessive at flood door frame from the root,
Avoid the unstable generation with sparking phenomenon of rail.
(2) rationally, structure is simple for the novel track system of the present invention across Flood gate, sleeper arrangement and railway roadbed design
It is single, it is easy for construction, there is good economic and technical effect.
