Abstract
A framed sleeper unit comprises two longitudinal sleepers and a plurality of horizontal sleepers. The horizontal sleepers are arranged between the longitudinal sleepers to form the frame sleeper unit. Two ends of each longitudinal sleeper are provided with joint structures to link two adjacent framed sleeper units. The frame sleeper units are laid on a granular-mixture ballast bed or a concrete ballast bed along a railway track direction, and rails are placed on a rail bed and connected with the sleepers through a fastening system. The framed sleeper unit has the advantages that under wheel load action, crushing never occurs to the rail seat; contact areas of the sleepers and the ballast bed are expanded, pressure applied to the top face of the ballast bed is reduced, and stability of the rail structure is improved; influence of wheel rail impact load to the ballast bed is reduced; rail support uniformity is enhanced, and rail surface dynamic harshness is maintained; maintenance of the ballast track of a high-speed railway is facilitated, and maintenance cost is lowered.
Description
Technical field
The invention belongs to railway traffic technical field, relate to track structure, be particularly applicable to the sleeper of severe cold Frozen Ground Area high-speed railway, urban track traffic and place, common railway station section etc.
Background technology
Track is one of primary structure of railway infrastructure, guarantee that high-speed railway normally runs, and will must control to some extent track malformation.High-speed railway often adopts ballastless track structure, is subject to unfreezing and causes rail level to sink, cause bullet train speed limit or stoppage in transit time serious in some seasonal frozen ground subgrade section track structures.Railway department has to carry out maintenance to circuit, especially ballastless track structure designs by few maintenance or maintenance-free requirement, like this, railway department renovates roadbed after the track structure in this section can only being removed, and the maintenance cost so brought is more much more than Ballast track.In addition, urban track traffic tunnel structure is uneven along line direction sedimentation, will certainly bring bad track irregularity, in order to the track irregularity that the differential settlement controlling these circuits brings, objectively needs a kind of novel sleeper.
Summary of the invention
The object of the present invention is to provide a kind of frame-type sleeper, its whole structural stability is good, is beneficial to high-speed railway Ballast track maintenance, reduces maintenance cost.
The present invention is achieved by the following technical solutions:
A kind of frame-type sleeper, comprising: two longitudinal sleepers and some transverse sleepers, and transverse sleeper is arranged at common formation frame-type sleeper between two longitudinal sleepers; The two ends of described longitudinal sleeper arrange connecting structure, and two adjacent frame-type sleepers are interconnected.
Further, described transverse sleeper connects perpendicular to longitudinal sleeper, and each transverse sleeper is spaced; Preferably, be spaced identical; Or preferably, described transverse sleeper mid portion offers groove.
The bottom surface of described longitudinal sleeper and the bottom surface of transverse sleeper are in same plane, and the upper end face place plane of transverse sleeper is lower than the upper end face place plane of longitudinal sleeper;
Or, the bottom surface of described transverse sleeper and upper end face place plane respectively with the bottom surface of longitudinal sleeper and upper end face place plane in same plane.
The bottom surface of longitudinal sleeper and the bottom surface of transverse sleeper, in same plane, increase sleeper and railway roadbed contact area, reduce the pressure of roadbed.
In described longitudinal sleeper, some arrangements of reinforcement are crossing with some arrangements of reinforcement in transverse sleeper, are conducive to the bulk strength improving sleeper.
Described frame-type sleeper is that length is roughly the same with width, and sleeper bending resistance is died down, and anti-extrusion ability strengthens.
Described longitudinal sleeper top arranges track, and described track has screwed hole; Preferably, described track is square; Or preferably, described track is arranged at longitudinal sleeper and transverse sleeper intersection area; Or preferably, the screwed hole that two diagonal angles that described track is provided with are arranged is used for connecting rail fastener system;
Or preferably, described transverse sleeper has four, described every root longitudinal sleeper top arranges four tracks.
The connecting structure that described longitudinal sleeper two ends are arranged is mutually chimeric plush copper and groove; Preferably, longitudinal sleeper one end arranges square plush copper, other end setting party connected in star;
Preferably, between described plush copper and groove, adopt matched in clearance, be beneficial to installation and removal convenient.。
In order to prevent the sleeper relative settlement of two pieces, front and back, longitudinal sleeper joint upper surface or side surface can arrange connection attachment strap.
The present invention also provides a kind of above-mentioned railway in length and breadth to the using method of staggered frame-type sleeper, by this in length and breadth to staggered frame-type sleeper laying in have on tiny fragments of stone, coal, etc. granular ballast bed or concrete road bed on, lay along railway track direction serial connection, then rail is positioned on track, by fastener system, rail is connected with sleeper.Fill up railway ballast in frame-type sleeper inner frame, increase the vertical lateral resistance between sleeper and railway roadbed, improve the stability of track structure.
Owing to have employed technique scheme, the present invention has following beneficial effect: 1. rail chair area is large, can reduce the pressure from rail, fully can ensure that rail chair does not produce conquassation under wheel load effect; 2. increase sleeper and railway roadbed contact area, reduce the pressure of roadbed; 3. fill up railway ballast in inner frame, increase the vertical lateral resistance between sleeper and railway roadbed, improve the stability of track structure; 4. sleeper quality is comparatively large, and self natural frequency reduces, and can slow down the impact of wheel-rail impact load on railway roadbed; 5. the contact surface of sleeper and railway roadbed is crisscross, and counter-bending change ability dies down, and anti-extrusion ability strengthens; 6. can prefabrication, the uniformity of rail supporting can be improved, the dynamic ride comfort of rail level can be kept preferably; 7. be conducive to high-speed railway Ballast track maintenance, reduce maintenance cost.
