Definitions

  • large panel sleepers or reinforced concrete including prestressed concrete or of steel are placed on the bottom ballast previously fully rolled to flatness with the gaps filled in with smaller crushed stones; the top-ballast is spread and rolled around the sleepers; rails are laid and fastened over the sleepers; the rail top is lifted to a specified height; a quick-hardening material is injected into the space between the base of the sleepers and the top surface of the bottom ballast to form an elastic hardened layer; a waterproof coat. made of .a quick-hardening waterproofing material is provided on the surface of the top ballast; and a gutter to drain the rainwater from the ballast is provided along the sides of ballast.
  • the present invention relates to an improvement of the ballasted track structure.
  • the present invention provides particularly an improved track structure which can hold the progress of track irregularitiesunder high-speed, high axle load and high-density train operation to a minimum, with the settling of the conventional ballasted track structure due to the ballast being minimized.
  • the commonly used railway track structure is a socalled ballasted track structure, wherein cross-ties are continuously laid on ballast, with rails fastened to the cross-ties by means of a rail-fastening device.
  • the ballast is vibrationally compacted by means of tie-tampers, etc.
  • the width of the cross-ties is commonly set at 20-30 cm and the tie-to-tie distance set at least at 20 cm. These values have been chosen to permit effective work with the tie-tamper, etc. It is desirable, however, as mentioned hereinafter that, if possible, the width of the ties be increased to give a greater base and width. Meanwhile, it has been revealed that the vibrational compaction by tie-tampers or the like itself contributes to the settling of ballast.
  • ballastless slab track structure In addition to the above-mentioned ballasted track structure, recently a ballastless" slab track structure has been proposed as an improvement. This proposal is fundamentally different from the ballasted one in that an elastic deformation of the track in the former absorbs energy of train and an artificial correction of track is not needed. But, if in this structure the heavy train load is to be borne through elastic deformation alone, special installation will be required for spreading the load and providing elastic elements. Thus, it would particularly be difficult to realize such a stucture through a short-term work on lines with ballasted track in existence.
  • an object of the present invention is to provide an improved ballasted track structure which is free from the major factors causing rail deflection inherent in the conventional ballasted track structure and the attendant maintenance practice, and which can minimize the progress of track irregularities under high-speed, [high axle load and high density train operation.

  • An additional object is to coat the top ballast surface with a waterproof layer to prevent the rainwater from invading the ballast or roadbed, thereby averting a rail deflection as far as possible.
  • Still another object of the present invention is to provide an improved ballasted track structure which can be installed easily and with few materials and within limited train intervals by using a quick hardening material and which permits train operation immediately after installation.

  • the waterproof layer formed on the top surface of said top ballast is provided with a drainage gradient.
  • crushed stones of a size smaller than that of said bottom ballast are spread on the rolled surface of said bottom ballast prior to placing said large panel sleeper thereby controlling the injected depth of the material into the ballast.
  • quick-hardening injection material is of a thermoplastic nature, such as asphalt, synthetic resin or mix- 'tures thereof, and is injected in a hot molten state and allowed to cool and harden whereby an extensive solid mass is formed with the voids in the ballast filled up..

  • bottom ballast 3 has been elaborately rolled on a roadbed 8, with smaller crushed stones 32 filling the gaps therebetween.
  • the height of the bottom ballast is usually set at about l5-25 cm.
  • a specified portion of the thus-formed ballast usually at the center following the longitudinal axis of the ballast, are continuously placed, with a specified interval, large panel sleepers 2 and 2' of the same size in two rows.
  • the opposite sleepers 2 and 2, constituting the two rows, are arranged parallel with a specified spacing, ballast being spread and rolled around the sleepers to form top ballast 33.
  • the height of the top ballast 33 is usually set at about l5-25 cm.
  • Each large panel sleeper can be a prestressed concrete member with a profile as illustrated in FIGS. 1 (a) I (c) or a steel member of the prior art with art-cross section as illustrated by numeral 21 in FIG. 1 (d).
  • the prestressed concrete sleepers 2 and 2' illustrated in FIGS. 1 (a) (c) are approximately rectangular cubes, each with the top surfaces of the two end portions thereof in the axial direction of ballast being formed as downward inclined surfaces 24 (FIG. 1 (b)) at a certain angle and recess 31 being provided at the mid-point of the bottom surface.
  • the large panel sleeper can be a simple rectangular cube. Rails 1 are laid over these two rows of large panel sleepers and fixed thereto by rail-fastening devices 7 of the prior art provided at equal intervals in the longitudinal direction of the large panel sleepers.
  • the width W, of the large panel sleepers 2 and 2' can be set at, e.g., cm for the narrow track gauge 1,067 mm and, say, cm for the standard track gauge of l,430 mm; while the length L can be set regardless of the track gauge, at from about 50 cm to 300 cm. To accomplish the purpose of the present invention, however, the valueof L is preferably over 50 cm. Desirable preferred values of the tie-to-tie distances g W can be as follows; g, 10 cm; W 18 cm for the narrow. gauge and about 20 cm for the standard gauge. The reason for selection of these values are as follows:
  • the value W has been selected tomake it possible to existing track in a limited time without dismantling the rails especially on so-called long-rail sections.
  • the value of W being set smaller than rail-to-rail distance RD permits easy insertionof a large panel sleeper between the rails and accordingly, the placement of the large panel sleepers in the position indicated in FIG. 1 (a) ('e) can be made easily.
  • the value of L depends on the spacing of the rail fastening devices 7, the number of such devices to be provided on one large panel sleeper and tie-to-tie distance g Regardless, both design and handling restrictions make the value of over 50 cm desirable. Tieto-tie distance g, for reasons of ballast resistance and working, is preferably about cm.
  • W is automatically set from the relation between W and the track gauge.
  • Two large panel sleepers laid in opposition to each other in the longitudinal direction of the ballast, when the ballast resistance is not large enough, may be linked together by say, turn buckle 23 of the prior art as illustrated in FIG. 1 (a), 1 (c) and 1 (d), thereby supplementing the ballast resistance.
  • FIGS. 2 (a) and 2 (b) illustrated another embodiment of a large panel sleeper.
  • large panel sleeper 22 can again be of reinforced concrete including prestressed concrete or of afi-shaped steel as in the embodiments of FIGS. 1 (a) l (e).
  • large panel sleepers 22 are provided only inya single row with both rails being laid on the single row.
  • An example of the desirable dimensions of a large panel sleeper in this embodiment, is as follows: L 73 cm; W 200 cm for the narrow gauge and 240 cm for the standard gauge; g about 10 cm.
  • L be set smaller than the distance between the oppositely laid rails.
  • elastic hardened layer 6 made of a quick-hardening injection material is formed in the space between the base of large panel sleepers 2, 2' 21 and 22 and the surface of the bottom ballast beneath said large panel sleepers.
  • the injection material can be a l 1 mixture, heated and molten, of a straight asphalt (penetration less than l0) and bronze asphalt (penetration l0 or an asphalt mixed with a small amount of a substance which is thermoplastic at low temperatures such as polyethylene.
  • This injection material is injected into the large panel sleeper through injection holes 25.
  • the injection material is necessarily heated before injection to improve fluidity to thereby fill up voids in the ballast. After passing through the voids in the ballast, the hot injectionmaterial goes also into the adjacent ballast.
  • the material consolidates the adjacent portion of the ballast into integral ballast cohesion 61.
  • cohesion takes place to the desired depth, it is possible to minimize vibrational deflection of ballast in the track structure of the invention.
  • the depth of cohesion 61 be set smaller than the ballast thicknesiso that the rail and bridge may bemutually insulated at. ballast layer.
  • the depth of ballast cohesion 61 depends on the type of the injection material, the heating temperature forinjection and particle size of ballast including smaller crushed stones 32.

  • ballast differs depending on the train speed. According to the result of practically measuring a train running at over 200 km/hr., 25 cm thick ballast having a 10 cm thick top ballast developed 1 g in the top ballast and in the bottom ballast developed less than I g. Thus, it is learned that cohesion of the ballast to at least 10 cm from the top can effectively prevent the ballast deflection. It is known, meanwhile, that the depth of ballast cohesion is practically governed by spread amount of small crushed stones 32 and preferable range of thickness of small crushed stone layer is l-4 cm.
