Rail fastening ars. Railway sleepers ars Anchor rail fastening ars 4 blueprint
APC reinforced concrete sleepers are designed for use on all railway lines in the main, station and other tracks, as well as sidings industrial enterprises, through which the typical rolling stock of the general network railways Russian Federation.
APC sleepers must meet the requirements for crack resistance adopted during their design and withstand test loads during testing, in accordance with GOST R 54747-2011.
The sleeper should be made of heavy concrete in accordance with GOST 26633, compressive strength class B40.
The required transfer strength of concrete must be at least 34.2 MPa (349 kgf/cm).
The frost resistance grade of concrete must be at least F200.
reference weight reinforced concrete sleepers 280 kg.
To reinforce the sleepers, carbon steel wire of a periodic profile with a diameter of 3 mm in accordance with GOST 7348 or TU 14-4-1681 should be used.
Nominal number of reinforcing wires in a sleeper ARS 44.
The total force of the initial tension of all reinforcing wires in the package must be at least 358 kN (36.4 tf).
ARS sleepers are designed for use in conjunction with anchor rail fastening. The ARS railway sleeper is equipped with fewer parts for attaching to the rail, which significantly reduces the weight of each kilometer of track by an average of 13-14 tons. Significantly reduces the amount of work on the assembly of the rail-sleeper grid. When using the ARS sleeper, it is possible to automate the assembly process at the link assembly base. The use of the ARS sleeper ensures that the rail bars are secured against longitudinal movements. There is no need to periodically tighten the elements. This reduces the cost of maintenance work on the track.
Seamless tracks based on anchor rail fastening have the following advantages:
the ARS fastening itself is about 7 kg lighter than the KB-65 fastening, which makes it possible to reduce the weight of each kilometer of the railway track by about 13 tons;
the APC mount has fewer parts, which greatly simplifies the installation process;
design features of the ARS fastening allow to partially automate the process of assembling the rail-sleeper grid;
there are no parts that need to be lubricated and tightened;
the possibility of straightening the railway track up to 25 mm in level;
The simple design of the ShS-ARS sleeper ensures reliable bonding, which, among other things, makes it possible to increase the speed of trains.
The ARS sleeper has a number of advantages. It is easy to operate, reliable and therefore has a high level of safety. Durable and therefore more cost-effective. Thanks to the design of the ARS, the service life of a reinforced concrete sleeper is doubled without major repairs. Significantly increases the stability of the rail track.
The design of the ARS sleeper allows you to significantly increase the average speed of trains. Its reliability and simplicity allows you to reduce the amount of time for examination and Maintenance. One of the main reasons is the absence of bolts and nuts - which usually require regular lubrication and additional tightening.
As a result, thanks to the ARS sleeper, the wear of the rail is significantly reduced, and significantly increases during its service life. Rail replacement is simplified - more precisely, it is not necessary.

Scope of ARS fastening.
An unlined track with ARS fastening and reinforced concrete sleepers ShS-ARS or sleepers Sh-A05 (with improved performance characteristics for longitudinal and transverse shear, reinforced central and end parts), can be laid:
in straight sections of the railway track and curves, with a radius of 350 m or more, with a rail gauge of 1520 mm (experimental sections are laid in curves with a radius of less than 300 m; experimental work on sleepers ShS-ARS-K for track sections in curves, with a gauge of 1530 mm, and for transitional with a variable gauge of 1522, 1524, 1526 and 1528 mm);
on bridges, with a ride both on ballast with sleepers of the ShS-ARS-M type with fastening elements for security devices, and with a ballastless bridge deck;
with sleepers of the ShS-ARS-Ch type for laying security devices in the shuttles and of the ShS-ARS-Ch1 type for laying within the shuttle and the entire bridge with a ballast layer between the shuttles;
in tunnels (the design of the vibration-protective path on the beds has been developed).
Due to climatic conditions, ARS fastening can be used in regions with different annual rail temperature ranges.
2. The main features of the design of ARS fastening and sleepers ShS-ARS, Sh-A05. Their specifications.
Elastic rail fastenings of the ARS-4 type (anchor intermediate rail fastening) are being actively introduced on the railways.
ARS fasteners belong to the type of unlined elastic fastenings. It is operated on high-load and high-speed lines with increased axial loads, including in subways.
Scope of ARS fastening.
This type of fastening is used for attaching R65 rails (for wide gauge) to reinforced concrete anchor sleepers of the ShS-ARS or Sh-A05 4x10 type. An unlined path is formed, which can fit in the following cases:
Straight and curved sections of the railway track with a radius of 350 m or more with a rail gauge of 1520 mm. Experimental sections were laid with APC fasteners, where the radius of the curve is less than 300 m.
Ballasted bridge deck with sleepers of the ShS-ARS-M type for ARS fastenings with elements of security installations for shuttles. Installation on a ballastless bridge deck is possible.
With reinforced concrete sleepers of the ShS-ARS-Ch type for laying track sections in curves of small radii. With elements of security devices for shuttles.
Tunnels (the design of a vibration-proof railway track on reinforced concrete beds has been developed).
Advantages of the anchor rail fastening: high reliability, stability of the rail track, low detail and lack of threaded parts, ease of assembly and operation, saving of materials.
sleeper type ShS-ARS designed for 1520 mm gauge railways, and are used with R65 rails and intermediate rail fastenings of the APC type.
APC fastening anchors embedded in a sleeper must comply with TU 3185-005-01115863-2004 and working drawings APC-04.04.005-03, APC-04.04.005-04.
Sleepers ARS must meet the requirements for crack resistance adopted during their design and withstand the control loads during testing.
The sleeper should be made of heavy concrete in accordance with GOST 26633, compressive strength class B40. The required transfer strength of concrete must be at least 34.2 MPa (349 kgf/cm). The release strength of concrete must not be less than the above transfer strength of concrete. The frost resistance grade of concrete must be at least F200. For concrete sleepers, crushed stone from natural stone or crushed stone from gravel of a fraction of 5-20 mm according to GOST 26633 should be used. It is allowed, by agreement between the manufacturer and the consumer, to use crushed stone of a fraction of 20-40 mm in an amount of not more than 10% of the mass of crushed stone of a fraction of 5-20 mm according to GOST 26633. Approximate weight of reinforced concrete sleepers ShS-ARS= 280 kg.
Reinforced concrete anchor sleeper type ShS-ARS for 1520 mm gauge railways is designed for attaching R65 rails with intermediate rail fastenings of the ARS type. Anchor reinforced concrete prestressed sleepers of the ShS-ARS type can be used on the railway network, including those with high traffic density and increased axial loads.
