Description
Technical field
The utility model belongs to railway engineering building element field, and in particular to a kind of " X " type anti-slide sleeper.
Background technique
For railway as important means of transport, effect and function are extremely crucial in traffic transport industry.Nowadays with
Railway is to high speed, the development of heavy duty and environmentally friendly direction, and requirement of the railway transportation to track is increasingly stringenter, such as Gao Pingshun
Property, high stability, high-durability etc..Sleeper is guaranteeing rail space bit as the important receptacle portion between rail and railway ballast
It sets, the load that dispersion rail is transmitted to railway ballast plays an important role, therefore the working performance of sleeper and its durability become extremely crucial.
It is excessive to there is route lateral displacement in multiple investigation in recent years, the phenomenon that longitudinal tip tilt, route is steady
Surely it needs to reinforce, especially in minor radius or the location of steep gradient, wheel is applied to the cross of track, and longitudinal force can significantly increase, edge
Train direction of travel and sleeper, which laterally have, to be displaced and easily causes between sleeper and shoulder railway ballast loosens.Because above-mentioned reason is not only
The conevying efficiency of railway is influenced, and increases the operations risks of railway.Therefore track structure is stablized in sleeper design at this stage
The requirement of property increases.
The existing type concrete sleeper model of Ι, II, III is fixed, and convenient for large-scale production, design can rationally be transmitted rail
Pressure be evenly transferred on railway roadbed, have certain stability.But since sleeper is "-" type, in train traveling process
It easily causes displacement of sleepers and loosens railway ballast, decline railway roadbed stability, be easily destroyed, increase maintenance expenditure.Concrete is wide
Although sleeper and fragment-free track slab can promote working performance, concrete production cost of material is high, has surmounted current reduction
The meaning of carbon emission amount and environmental protection is only applicable to high speed, heavy-haul line.Currently, sleeper foundation construction is different with paving location to be had
It is several below: transverse sleeper, longitudinal sleeper, ladder shape sleeper, double-block type sleeper and the Y type rail for improving track bending-twisting rigidity
Pillow.
According to State Council's " long-term railway network planning of China " and accelerate railway construction, expansion road network scale, improved technology
The demand of the spirit of equipment, China's sleeper at this stage is huge.Traditional sleeper and reinforced concrete sleeper, which has been unable to meet, to be wanted
It asks, the exploitation advanced new sleeper of all technical is the inexorable trend of sleeper research and development.It is special in order to adapt to high-speed railway and passenger traffic
The technical requirements of trajectory carrying and track maintenance and repair, the general concrete sleeper for using enhanced type, including increase prestressing force and match
Muscle and depth of section improve the bearing strength at interface, and increasing section size and length of sleeper etc. optimize configuration design and improve track
Horizontal, longitudinal stability.
Therefore for the requirement of the above-mentioned optimization design of existing sleeper, the purpose of this utility model is to provide a kind of optimization
The sleeper of the X-type structure of outer dimension, it possesses bigger sleeper cross dimensions than traditional prestressing force monoblock type sleeper, to improve
The longitudinal resistance and stability of route；Bigger sleeper side and bottom surface contact area and integrated design can increase sleeper
Transverse and longitudinal resistant slide ability, reduces that sleeper is horizontal, length travel, and more evenly to railway roadbed power transmission, this outside dimension be unanimously convenient for manufacture,
Transport, construction and later period make maintenance firm by ramming.
Utility model content
Existing sleeper there are aiming at the problem that, the utility model be optimize sleeper outer dimension and construction use technology
Scheme is as follows:
A kind of X-type anti-slide sleeper, it is characterised in that: including the sleeper main body in X-type arrangement, along four extension sides of X-type
To sleeper section on be equipped with rail mounting groove, it is symmetrical up and down between four rail mounting grooves, along four extending directions of X-type
Sleeper section upper and lower surface height it is consistent.
The sleeper main body is made of reinforced concrete structure, and sleeper main body is intersected along the sleeper section of sleeper X-type direction
Reinforcing rib is set, sleeper strength is increased.
The parallelogram short side of the rail mounting groove and parallel, the inclined bottom surface of rail trend, gradient 1:40, steel
The bottom of rail mounting groove and the bottom surface distance of sleeper are 220mm-250mm.
Groove is equipped in the middle part of the sleeper main body, groove floor and sleeper lower surface distance are 190mm-210mm convenient for knot
Structure draining.
The sleeper main body is consistent along four extending direction bottom widths of X-type, width 240mm-320mm.
Rail installation slot center spacing of the sleeper main body along the rail extending direction of the same side, in two adjacent sleeper sections
600mm-1000mm。
Distance is 2200mm-2600mm between the symmetrical outwardly extending lip of two of the sleeper main center block two sides.
The rail installation trench bottom offers several rail attachment fastener bolts hole, fixes rail for fastener for installing,
Bolt hole opens up size according to using fastener model to select.
The utility model has the advantages that
X-type anti-slide railroad sleeper provided by the utility model can effectively increase sleeper and rest the head on connecing for shoulder and shoulder railway ballast
Contacting surface product, disperses sleeper stress to four angular ranges of X-type, keeps sleeper big in direction of traffic and lateral antiskid kinetic force
It is big to improve, it reduces because the railway ballast of sleeper sliding generation is loose, broken, guarantees the operation of train safety and steady, power transmission is more uniform, mentions
The stability of high railway roadbed and maintenance period.
