Definitions

  • the invention relates to a sleeper for a railroad section, a railroad section and a method of laying down a railroad
  • a method used today for building a dual-track railroad is to cover a part of the embankment with large and heavy steel plates, partially laying down one layer of ballast on a non-covered part of the embankment, moving the plates to the other side of the embankment where the railroad is intended to be laid down, further laying down the ballast and another layer of ballast on a non-covered part of the embankment, and moving the plates again to finish the other layer of ballast on a part of the embankment not covered by the steel plates.
  • the weight of such plates - or the amount of plates to be moved in case smaller plates are used in view of the weight - moving the plates so often is a cumbersome and time-consuming work.
  • heavy and expensive equipment is required.
  • the plates are still used as a road for tracked or wheeled vehicles, in particular lorries carrying material.
  • ballast with wheeled vehicles by driving over ballast they have dumped, to avoid direct contact between the wheels and the embankment.
  • the impression in the embankment will still occur through pressure via the dumped ballast, causing the same problems as the ballast will simply transfer the amount of pressure applied onto the embankment. This, in turn result in stability issues of a railroad that is finally laid down on the embankment.
  • the invention provides a sleeper for a railroad section, the sleeper comprising a main body having an elongated form, a bottom side and two elongated sidewalls adjacent to the bottom side and a surface extension element connected to either the bottom side or at least one of the two elongated sidewalls for extending the bottom surface area of the sleeper.
  • a temporary railroad track is to be build on the embankment.
  • a force exerted on a railroad section comprising the sleeper by for example a train riding on the railroad section is distributed over a relatively large area. This will leave a relatively shallow impression on the embankment, resulting in conservation or at least less deterioration of the integrity of the embankment.
  • At least one additional sidewall is connected to at least one elongated side of the surface extension element, the additional sidewall having a substantially rectangular shape of which the elongated side is connected to an elongated side of the surface extension element.
  • the sleeper is formed by a reversed U-profile and the surface extension element is formed by another U-profile having another bottom part that is larger than a bottom part of the reversed U-profile.
  • sleepers thus created are hollow and therefore relatively light, requiring relatively light equipment to handle those sleepers or a railroad section comprising such sleepers.
  • the invention provides in a second aspect a railroad section for transporting a vehicle over a ground section, the railroad section comprising two rails, sleepers connected substantially perpendicular to the underside of rails at the top side of the sleepers and at least one surface extension element having a substantially flat underside connected at or near the bottom side of the sleepers, thus increasing a bottom surface area of the railroad section, either continuous or segmented, said bottom surface area being defined as the total surface of the bottom side of the sleepers and the surface of the surface extension element that is not overlapped by a sleeper.
  • a temporary railroad track is to be build on the embankment.
  • a force exerted on a railroad section comprising the railroad section by for example a train riding on the railroad section is distributed over a relatively large area. This will leave a relatively shallow impression on the embankment, resulting in conservation or at least less deterioration of the integrity of the embankment.
  • An additional advantage of such a railroad section is that a temporary or auxiliary railroad track can be pre-fabricated to a large extent. This, in turn, results in less time being required for the final construction of the temporary or auxiliary railroad track. This is because only the railroad sections have to be laid down and connected.
  • sleepers according to the invention are employed.
  • An advantage of this embodiment is that sleepers can be produced in series and shipped in a compact way to a location where the railroad section is to be constructed.
  • the surface extension element is formed by a plate connecting multiple sleepers.
  • An advantage of this embodiment is that such railroad track comprises less edges, thus reducing the risk of damaging the upper surface of the embankment.
  • the invention provides in a third aspect a method of laying down a railroad comprising at least a first track and a second track, both tracks being substantially parallel to each other, the method comprising: laying down an auxiliary track at the intended location of the first track, laying down a section of the second track with at least one piece of equipment located on the auxiliary track; laying down another auxiliary track at the intended location of the second track, in line with and connected to the section of the second track already laid down; laying down a section of the first track with at least one piece of equipment located on the other auxiliary track; laying down a further auxiliary track at the intended location of the first track, in line with and connected to the section of the first track already laid down and repeating the previous four steps until the desired length of the railroad is established.
  • the auxiliary track has to be laid down only once without further displacement other than removal, this method enables a more efficient and convenient, but also faster way of laying down a railroad.
  • the auxiliary track comprises at least one sleeper according to the invention.
  • the auxiliary track comprises at least one railroad section according to the invention.
  • At least one of the auxiliary tracks comprises multiple railroad sections as claimed in claim 11, said railroad sections comprising at least one horizontal hole through the rails near at least one end of the railroad section and a sub-method of connecting the railroad sections comprises: applying a fishplate comprising at least one hole parallel to a rail of the railroad section; aligning the hole in the fishplate to the hole in the rail in the rail of the road section; inserting a bolt comprising a groove over at least a part of the length of the bolt in the hole in the fishplate and the hole in the rail in the rail of the road section; inserting a key in the groove in the bolt; and connecting the fishplate to another rail.
  • the advantage of this embodiment is that railroad sections are connected in a fast and convenient manner that has appeared to be more practical than using bolts and nuts to be screwed on said bolts.
  • the auxiliary track, the other auxiliary track and the further auxiliary track comprise the same track sections by re-using said same track sections in different steps.
  • An advantage of this embodiment is that less material is used by recycling material that is not required any more for other purposes.
  • FIG. 1 discloses a sleeper 100 as an embodiment of the sleeper according to the invention.
  • the sleeper 100 comprises a main body 110 formed by a top part 112, a bottom part 114, a first sidewall 116 and a second sidewall 118. This implies that the main body 100 is hollow.
  • a solid main body can be envisaged as well, though this is not preferred as this would increase the weight of the sleeper 100.
  • a low weight of the sleeper 100 is preferred, as will become apparent in the further course of the description.
  • first baseplate 122 and a second baseplate 124 are provided on top of the main body.
  • the first baseplate 122 and the second baseplate 124 are conceived to receive a rail (not shown).
  • the base of the first baseplate 122 and the second baseplate 124 are slightly inclined, being lower towards the centre of the sleeper 100 and higher towards the edges of the sleeper 100.
  • the angle is between 0° and 5° and an angle of 2,5° is particularly preferred.
  • the sleeper 100 further comprises a first surface extension element 132, a second surface extension element 134, a first additional sidewall 136 and a second additional sidewall 138.
  • the second additional sidewall 138 is connected to the second sidewall 118 via a reinforcement element 140.
  • several more reinforcement element are provided for connecting the second additional sidewall 138 to the second sidewall 118 and for connecting the first additional sidewall 136 to the second sidewall 116.
  • a person skilled in the art will appreciate that an embodiment with only one surface extension element instead of two can be envisaged as well, without departing from the scope of the invention.
  • the reinforcement elements 140 are provided in the vicinity of the first baseplate 122 and the second baseplate 124. Within the hollow main body 110, also reinforcement elements 140 are provided. Preferably, the reinforcement elements 140 are provided in line, within as well as outside the main body 100.
  • a preferred way of constructing the sleeper 100 is by welding a reversed U-shaped profile forming the top part 112, the first sidewall 116 and the second sidewall to a U-shaped profile forming the bottom part 114, the first surface extension element 132, the second surface element 134, the first additional sidewall 136 and the second additional sidewall 138. Before welding both U-shaped profiles together, the reinforcement elements 140 are welded inside the reversed shaped profile.
  • first additional sidewall 136 and the second additional sidewall 138 have a rectangular shape and are connected at their elongated sides to elongated sides of the first surface extension element 132 and the second surface extension element 134, respectively.
  • the additional sidewalls are connected perpendicular to the surface extension elements.
  • the angle between the additional sidewalls and the surface extension elements can be varied without departing from the scope of the invention.
  • the angle between the additional sidewalls and the surface extension elements is in the range of 45° and 135°, where an angle of 90° is most preferred.
  • the standard width of a railroad track is 1435 mm, in 60% of the world. This size is measures between two rails, measured from inner side to inner side. For such a railroad track, a full length of the sleeper 100 of 2500 mm is preferred. The same length is preferred for the first surface extension element 132 and the second surface element 134.
  • the preferred distance between the centres of the first baseplate 122 and of the second baseplate 124, the distance indicated by the "A" in Figure 1 , is 1500 mm.
  • the width of the sleeper is preferably 190 mm and the preferred width of both the first surface extension element 132 and the second surface element 134 is 155 mm.
  • the preferred distance between two reinforcement elements 140 adjacent to or under either the first baseplate 122 or the second baseplate 124 is 130 mm.
  • Figure 2 discloses a railroad section 200 as an embodiment of the railroad section according to the invention.
  • the railroad section 200 is depicted upside-down.
  • the railroad section 200 comprises four sleepers 100 and two rails 210.
  • the railroad section 200 comprises a further surface extension element 220.
  • the further surface extension element 220 is in this embodiment provided as a continuous rectangular plate.
  • the further surface extension element 220 is segmented and distributed over only a small plurality of sleepers 100.
  • the further surface extension element is welded to the sleepers, though the connection may also be made by other means, like nuts and bolts or other.
  • the further surface extension element 220 may also be provided in other shapes, though still preferably with a flat bottom surface, i.e. the surface facing away from the sleepers 100.
  • the further surface extension element 220 is provided alternatively to the first surface extension element 132 and/or the second surface extension element 134, including the first additional sidewall 136 and the second additional sidewall 138.
  • such further surface extension element may also replace bottom parts of individual sleepers.
  • the first surface extension element 132 and/or the second surface element 134 suffice for the purpose for which they are provided, the further surface extension element 220 may be omitted. The purpose of all surface extension elements will be further explained in the further course of the description.
  • the railroad section 200 is intended to be used for building a temporary or auxiliary railroad track for construction purposes. Therefore, it should be convenient to be transported, for which reason it should not be too heavy, as indicated before, and not be too large or too long.
  • a length of about 12 meters is preferred, with a centre-to-centre distance of the sleepers 100 of 600 mm. This results in having 20 sleepers for length of the railroad section of 12 meter. Calculations and experiments have indicate that such railroad section is most efficient to be used for construction of an auxiliary track. Among others, this is close to a safe limit of weight and length of constructions that can still be handled by a commonly used railway crane.
  • a sleeper with surface extension elements having a total width of 500 mm, a total length of 2500 mm, a railroad track with an inner width of 1435 mm and a heart-to-heart distance of sleepers of 600 mm - and an axle pressure of 200 kN per axle or 100 kN per wheel, a bedding constant of 20 MN/m 3 and ⁇ rep of 32,5°, the impression in the embankment is less than 10 mm.
  • Construction of a railroad track 300 starts with establishing an embankment 310, primarily comprising sand.
  • the top surface of the embankment 310 is levelled, creating a substantially flat and horizontal surface.
  • the embankment 310 is after creating it preferably left for a certain amount of time to subsidence. Integrity of the flat and horizontal embankment 310 is important for the following step.
  • Figure 3 B depicts a following step, being the deposition of a first ballast layer 322 comprising relatively fine cut granite.
  • the purpose of the first ballast layer 322 is to provide a sturdy foundation for a subsequent layer and sleepers of the railroad track 300.
  • a person skilled in the art will appreciate that also other material than granite may be used, like pebbles or rubble.
  • a subsequent second ballast layer 324 is deposited on top of the first ballast layer 322.
  • the second ballast layer 324 comprises cut granite as well, though with a coarser structure than the cut granite of the first ballast layer 322.
  • a railway 330 comprising sleepers and rails is constructed on top of the second ballast layer 324. Additionally and optionally, electrical conductors are provided over the railway 330 to power any vehicle intended to ride on the railroad track 300.
  • integrity of the flat and horizontal embankment 300 is important. Very often, this is in conflict with the need to transport ballast, sleepers, rails, other materials and equipment to the location where a railroad is to be constructed. In particular in case of construction of a new railroad, materials cannot be provided by train, using currently publicly known methods. Transport by wheeled vehicles - e.g. intended for road use, light freight lorries - is not desirable as such vehicles leave such imprints in the embankment 310 that the integrity of the flat and horizontal surface of the embankment 300 and therefore the stability of the railway 330 is compromised. Use of tracked equipment slightly relieves this issue, though such equipment still leaves significant imprint in the embankment 300.
  • the invention provides in its various aspects and embodiments surface extension elements for sleepers and/or railroad sections.
  • Such railroad section or a railroad section comprising such sleepers is used for laying down an auxiliary railroad track.
  • auxiliary railroad track is used for construction purposes only, it does not have to fulfil requirements as high as those for usual railroads. This is because construction trains and other vehicles driving on a railway for construction purposes drive at far lower speeds.
  • a auxiliary railroad has a temporary nature (usually in terms of days or weeks; sometimes months), whereas permanent tracks are intended for a lifetime of tens of years - or more.
  • the weight of a vehicle riding on such track is distributed over a larger area than with a normal railway having no surface extension elements. In this way, a potential imprint in the embankment 300 is far less than with a normal railway having no surface extension elements.
  • a total surface area of the railroad section being defined as the product of the length of a sleeper and the length of a rail and the maximum imprint as a constant
  • a bottom surface area of the railroad section required for a maximum imprint or a pre-determined depth, the bottom surface area being either continuous or segmented and defined as the total surface of the bottom side of the sleepers and the surface of the surface extension element that is not overlapped by a sleeper.
  • An important outcome of such a calculation is the ratio of the total surface area of a railroad section and the bottom surface area of that railroad section.
  • Figure 4A depicts a dual-track railroad 400 comprising a first existing railroad track 402 and a second existing railroad track 404.
  • an auxiliary railroad track 420 is laid down from the second existing railroad track 404 by laying out auxiliary railroad sections in line with the second existing railroad track 404.
  • the auxiliary railroad sections laid out are preferably railroad sections as discussed in conjunction with Figure 2 .
  • the auxiliary railroad sections are placed by a railway crane standing on the second existing railroad track 404 - and subsequently on the auxiliary railroad track 420 once this has been laid down. For this reason, the auxiliary railroad sections and its elements like the sleepers should not be too heavy. After placement, the auxiliary railroad sections are fixed to the existing railroad track 404 and subsequently already laid down auxiliary railroad sections by means of emergency fishplates. Emergency fishplates are provided on both sides of a rail.
  • a groove and in particular a tapered or conical groove is provided in the bolt. After the bolt has been inserted in the three holes, a tapered key or wedge is inserted in the groove and secured by means of hammering to tighten the connection. Alternatively, a nut screwed to the bolt to fixate the fishplates and the rail.
  • This fixating step is repeated for the other side of the emergency fishplates to connect two auxiliary railroad sections to each other or to connect an auxiliary railroad section to an already existing railroad section.
  • the full length of the auxiliary railroad track 420 depends on several conditions and in particular on the construction planning and the length of rails used to construct the dual-track railroad 400. Rails are currently available at various lengths, up to 360 meters. Preferably, the auxiliary railroad track 420 has the length of either one rail or a multiple of that length.
  • a first new railroad track 412 is laid down and constructed in line with the first existing railroad track 402.
  • the equipment and material for laying down the first new railroad track 412 are transported over the auxiliary railroad track 420.
  • Such equipment includes vehicles for transporting material for depositing material for ballast layers, equipment for equalising the ballast material to form ballast layers and vehicles for transporting and/or laying down sleepers.
  • Rails are supplied via the first existing railroad track 402 and pulled over the sleepers laid down at the intended location of the first new railroad track 412 and subsequently connected to the sleepers.
  • the auxiliary railroad track 420 is disassembled by removing the keys from the grooves in the bolts, removing the emergency fishplates and relocating the auxiliary railroad sections to a location in line with the first new railroad track 412, as depicted in Figure 4B . Subsequently, the first new railroad track 412 already laid down and the auxiliary railroad track 420 are used for laying down a second new railroad track 414 in line with second existing railroad track 404 in a similar way as the first new railroad track 412 has been laid down.
  • the auxiliary railroad track 420 is disassembled again and relocated to a new location in line with the second new railroad track 414 where it is reconstructed. Subsequently, the second new railroad track 414 and the auxiliary railroad track 420 are used for transporting construction equipment and materials for further construction of the first new railroad track 412 as depicted in Figure 4C.
  • auxiliary railroad track For purposes of among others traffic control (track circuits), it is important to prevent shorts between two parallel rails of a main railroad track.
  • auxiliary railroad track with railroad sections comprising steel sleepers and directly connecting the auxiliary track to the main railroad track, an undesired short would be created. Therefore, at least one section of the auxiliary railroad track 420 is provided with further rails which are connected to the rest of the auxiliary railroad section by means of insulated joints. In this way, the auxiliary railroad track is electrically isolated from the main track, preventing shorts between the two rails of the main track.
  • the invention may also be embodied with less components than provided in the embodiments described here, wherein one component carries out multiple functions.
  • the invention may also be embodied using more elements than depicted in Figure 1, Figure 2 or Figure 4 , wherein functions carried out by one component in the embodiment provided are distributed over multiple components.
