  However, such a block made of concrete must be installed using a heavy machine, which is costly and time consuming. For this reason, for example, when exchanging ballast, block installation or ballast exchange must be performed within a few hours when the train is stopped, and ballast exchange is performed over a long distance in a short period of time. I couldn't. In addition, in such a concrete block, the flow of water in the left-right direction is interrupted, so that there is no problem of water escape when heavy rain falls, and the roadbed becomes loose.

  Accordingly, the present invention has been made paying attention to the above problems, and provides a ballast stopper that can easily stop ballast and that allows water to flow in the left-right direction when heavy rain falls. With the goal.

  That is, in order to solve the above-described problems, the present invention provides a ballast stopper for preventing the collapse of ballast provided on a railway track, and a plurality of main bars that are bent in an L shape, and a transverse direction perpendicular to the main bars. It is made to be provided with the horizontal stripe provided in.

  By constructing in this way, it is possible to construct a very light ballast stopper by assembling the main and horizontal bars smaller than the ballast, and it will be possible to drain from between the main and horizontal bars, so that water will enter the track. It will be possible to prevent accumulation.

  In such an invention, the main bars are provided with a gap width smaller than the size of the ballast, and the horizontal bars are provided with a smaller number than the main bars.

  If it does in this way, while being able to endure the omission of the ballast and the pressing force by the ballast with the main reinforcement, it is possible to reduce the overall weight and reduce the cost by reducing the lateral reinforcement.

  Further, one of the transverse bars is projected in the lateral direction from the main muscle of the outermost side.

  With this configuration, when connecting the ballast stopper in the left-right direction, the protruding lateral stripe can be brought into contact with the adjacent main ballast of the ballast stopper, and the ballast stopper can be connected with the vertical wall surface aligned. Will be able to go.

  Further, the lower end of the main muscle protrudes from the horizontal muscle.

  With this configuration, when the ballast stopper is pushed into the back (track side) while the ballast is stacked, the tip side of the protruding main bar can be inserted into the gap between the ballasts, and the ballast can be pushed in while escaping. become.

  According to the present invention, in the ballast stopper for preventing the collapse of the ballast provided on the railroad track, it is provided with a plurality of main bars flexing in an L-shape and a horizontal bar provided in a direction orthogonal to the main bars. As a result, it is possible to construct a very light ballast stopper by assembling the main and horizontal bars smaller than the ballast, and it is possible to drain from between the main and horizontal bars, so that water accumulates in the track. Can be prevented.

  Hereinafter, an embodiment of a ballast stopper 1 according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the ballast stopper 1 in this embodiment includes a plurality of main bars 2 bent in an L shape, and a horizontal bar 3 provided in a direction orthogonal to the main bars 2. This makes it possible to withstand the pressing force of the ballast, to prevent the ballast from coming out, and to prevent rainwater from escaping from the gap between the reinforcing bars and preventing water from accumulating in the track. It is. Hereinafter, the configuration of the ballast stopper 1 in the present embodiment will be described in detail.

  First, the main bar 2 constituting the ballast stopper 1 is composed of a reinforcing bar having a diameter of about 6 mm to 8 mm, and is bent into an L shape having a height dimension of 400 mm and a horizontal dimension of about 400 mm. Provided. And, in order to be able to withstand the pressing force of the ballast by this main reinforcing bar 2, in order to prevent the ballast from coming off, the main reinforcing bars 2 are arranged as densely as possible so that the effective gap width is 20 mm to 27 mm smaller than the ballast. Yes. In addition, when using the main reinforcement 2 in this way, you may comprise only the thick main reinforcement 2 about 8 mm in diameter, for example, but if it does in this way, weight will become heavy and cost will also become high. For this reason, in this embodiment, as shown in FIG. 2, a thick main bar 2 is continuously provided so as to withstand the pressure of the ballast, and the main bar 2 is thin and adjacent to the main bar 2 having the large diameter. By disposing the main bar 2 having a diameter, it is possible to prevent the ballast from coming off. Here, the two thick main bars 2 and the two thin main bars 2 are alternately provided. However, the thick main bars 2 may be provided at regular intervals, and the thin main bars 2 may be provided therebetween. . Such an arrangement width of the main muscles 2 is arranged in a horizontal direction of 800 mm to 1200 mm so that an operator can carry it by hand.

  On the other hand, the horizontal bars 3 are provided in the left-right direction, and are welded to the outside of the bending main bars 2. This horizontal bar 3 plays a role of maintaining the gap interval of the main bar 2, and here, is composed of a reinforcing bar having the same diameter as the main bar 2 and having a diameter of about 6 mm to 8 mm. When welding the horizontal bars 3, it can be welded to the inside of the bent main muscle 2, but in this way, the ballast provided on the inner side where the main bars 2 bend directly hits the horizontal bars 3, and the load causes There is a possibility that the welding will come off. For this reason, the horizontal bars 3 are welded to the outside of the main bars 2.

  In the case where such horizontal stripes 3 are provided, the distance between the horizontal stripes 3 may be close to prevent the ballast from being lost. However, in the present embodiment, the main stripe 2 alone can prevent the ballast from being lost. Therefore, the number of the horizontal stripes 3 is reduced so that the manufacturing operation can be simplified and the cost can be reduced. Specifically, the lateral stripes 3 are arranged to have an effective gap width of about 123 mm to 125 mm with respect to an effective gap width of 25 mm of the main reinforcement 2 (31 to 32 mm between the cores). Moreover, when welding such a horizontal stripe 3, as shown in FIG. 1, about one edge part, it welds so that it may correspond with the main reinforcement 2, and about 25-30 mm from the main reinforcement 2 about the other end side. Keep it protruding. Thereby, when connecting the adjacent ballast stopper 1, the protruding horizontal stripe 3 can be brought into contact with the main reinforcement 2 of the adjacent ballast stopper 1 to align the vertical wall surfaces. On the other hand, the horizontal bar 3 of the bottom surface part 6 of the ballast stopper 1 is welded to the inner side of the tip of the main bar 2 so that the tip part 21 of the main bar 2 protrudes. In this case, the horizontal stripes 3 may be welded so as to coincide with the distal end portion 21 of the main reinforcement 2. However, when the ballast stopper 1 is pressed in the back direction, the linear horizontal stripes 3 are pressed against the ballast. As a result, the ballast stopper 1 cannot be pushed inward. On the other hand, if the front end portion 21 of the main muscle 2 is protruded, the front end portion 21 can enter the gap of the ballast, and the ballast stopper 1 can be pushed in while the ballast is released. . Then, the positions of the left and right ballast stops 1 are aligned and connected while adjusting the push-in dimension.

  The ballast stopper 1 provided in this way is connected in the left-right direction using a connecting member 4. As shown in FIG. 4, the connecting member 4 is provided in a U-shape, and the main bar 2 is accommodated inside the connecting member 4 so as to prevent lateral displacement and is fixed by a plate 41 or a flange nut 42. It can be done.

  Next, a method in the case of using the ballast stopper 1 configured as described above will be described.

  When using the ballast stopper 1, as shown in FIG. 5, the ballast stopper 1 is arranged over a plurality of stages. First, when installing the ballast stopper 1 of the lowest stage, the ballast stopper 1 is arrange | positioned to a horizontal direction on a roadbed. Thus, when arrange | positioning the ballast stopper 1, it arrange | positions so that the front-end | tip part 31 of the horizontal stripe 3 may contact | abut to the main reinforcement 2 of the adjacent ballast stopper 1, and uses the connecting member 4 in that state, Main muscle 2 and main muscle 2 are connected. At this time, it is preferable to place several ballasts on the bottom surface portion 6 so that the ballast stopper 1 does not fall down. And after connecting the ballast stopper 1 in this way, the ballast is piled up. At this time, since the ballast is placed on the bottom surface portion 6 of the ballast stopper 1 bent in an L shape, the vertical side wall surface 5 is fixed by the load, and the collapse of the ballast can be prevented.

  And the ballast stopper 1 is further installed on it in the state which the ballast was piled up in this way.

  When the ballast stopper 1 is installed on the ballast stacked in this manner, the ballast stopper 1 is displaced due to the unevenness of the ballast, but the main stripe 2 of the ballast stopper 1 adjacent to the lateral stripe 3 protruding in the lateral direction. The vertical side wall surface 5 can be aligned by bringing the ballast stopper 1 into contact with the back and pressing the ballast stopper 1 in the back. When the ballast stopper 1 is pressed to the back, the ballast stopper 1 is pushed into the back while letting the ballast pass through the tip portion 21 of the main muscle 2 and release the ballast. Then, with the vertical side wall surface 5 of the ballast stopper 1 aligned as described above, the connecting member 4 is attached to the main bar 2 and fixed with the plate 41 and the flange nut 42. In addition, the ballast is stacked on top of it.

  As described above, according to the above-described embodiment, in the ballast stopper 1 for preventing the collapse of the ballast provided on the railway track, the plurality of main bars 2 that bend in an L shape and the transverse direction perpendicular to the main bars 2 are provided. Since the main bar 2 and the horizontal bar 3 are smaller than the ballast, a very light ballast stopper 1 can be formed and the main bar 2 and the horizontal bar 3 can be formed. Since the water can be drained, water can be prevented from collecting in the track.

  Further, the main bars 2 are provided with a gap width smaller than the size of the ballast, and the horizontal bars 3 are provided in a smaller number than the main bars 2, so that the main bars 2 can withstand the ballast slip and the pressing force caused by the ballast. In addition, by reducing the horizontal stripes 3, the overall weight can be reduced and the cost can be reduced.

  Further, since the distal end portion 31 of the lateral bar 3 on one side of the horizontal bar 3 protrudes in the lateral direction relative to the outermost main bar 2, the protruding horizontal bar 3 when connecting the ballast stopper 1 in the left-right direction. Can be brought into contact with the main reinforcement 2 of the adjacent ballast stopper 1, and the ballast stopper 1 can be connected in a state where the vertical wall surfaces are aligned.

  Further, since the lower end portion of the main bar 2 protrudes from the horizontal bar 3, when the ballast stopper 1 is pushed into the back (track side) in a state where the ballast is stacked, the front end side of the main bar 2 that protrudes Can be pushed into the ballast gap while escaping the ballast.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect. For example, in the above embodiment, the distance between the main muscles 2 is increased to prevent the ballast from being lost. However, the mesh-like expanded metal is used to prevent the ballast from being lost, or the distance between the horizontal muscles 3 is increased. The ballast may be prevented from coming off densely.

  In the above embodiment, the main reinforcement 2 can withstand the lateral pressing force of the ballast. However, between the horizontal reinforcement 3 provided on the vertical side wall surface 5 and the horizontal reinforcement 3 provided on the bottom surface portion 6. In addition, a diagonal subsidy may be attached to withstand the lateral pressing force.

  Furthermore, in the above-described embodiment, the horizontal streak 3 protruding only on one side is provided, but the horizontal streak 3 may be provided so as to protrude on both sides.

  In the above embodiment, the ballast stopper 1 is connected by the connecting member 4. However, the horizontal bar 3 protruding in the lateral direction is bent into a hook shape, and the hook part is the main bar of the adjacent ballast stopper 1. You may make it connect with the hook part of 2 or the horizontal stripe 3, etc. FIG.
