Description

  The present invention relates to a level crossing pavement structure in which a level crossing pavement member is installed at a level crossing and forms a road surface such as a road, a level crossing pavement member installed in a level crossing and forms a road surface such as a road, a level crossing installed in a level crossing and constituting a road surface such as a road The present invention relates to a road surface member for a level crossing pavement that is attached to the surface of a pavement member to exhibit the function of the road surface, and a leveling pavement method that configures a road surface such as a road by installing a level crossing pavement member on the level crossing.

  Conventionally, at a railroad crossing (or railroad crossing) where a railroad track and a road, or a railroad track and a passage (a road or a passage in a railroad crossing is referred to as a “road or the like”) are used for traffic such as pedestrians and automobiles. Paved to serve.

  As an example of this level crossing pavement, although not shown, a pavement made of wood or a pavement made of pavement made of stone is laid on the inside and outside of two rails (rails). As another example of the laying material pavement, there is one in which a wooden sleeper is laid on the inside and outside of two rails (rails).

  In recent years, a level crossing pavement structure called a “joint track” has been used in a level crossing having a large width and a large amount of traffic. Although not shown in the figure, the connecting track is removed from the sleepers at the level crossings, and instead, plate-like connecting track plates made of reinforced concrete (RC), prestressed concrete (PC) or the like are laid out without gaps. In this articulated track, the left and right rails are accommodated in two groove-shaped rail accommodating recesses extending in the longitudinal direction of the rail provided on the upper surface of the articulated raceway plate, and the rails are accommodated by mounting bolts and nuts. It is designed to be fastened and supported on the bottom of the. The plurality of articulated track plates laid out are fastened in the rail longitudinal direction by a PC steel bar. Thereby, in the articulated track, the track and the level crossing pavement are integrated, and a “railway (a structure made up of a rail and a sleeper)” having a strong PC structure is formed.

  Also, at level crossings where the width of roads and the like is smaller and the traffic volume is relatively less than the level crossings where articulated tracks are used, a level crossing pavement structure using a level crossing pavement member called `` Soken-type level crossing pavement plate '' is used. . The level crossing paving structure using this type of level crossing paving slab is not shown, but is a so-called plate-like member made of reinforced concrete (RC) or prestressed concrete (PC) without removing the sleepers at the level crossing. Using the type crossing pavement plate, this level-crossing pavement pavement plate is attached to the upper surface of the sleeper outside and inside the track of the crossing point to pave the crossing point.

  Also, without crossing the sleeper at the level crossing, a wide plate-shaped level crossing pavement made of reinforced concrete (RC) or prestressed concrete (PC) is used. As a structure for paving a railroad crossing location by laying and mounting on the upper surfaces of the inner and outer sleepers, a structure called an “assembled paving plate type railroad paving structure” is also known (see Patent Document 1). In the case of the level crossing pavement structure using the “Skenken type crossing pavement plate” and the “assembled pavement plate type crossing pavement structure”, the pavement plate can be laid and removed with a crane or the like in a short time. The construction cost can be reduced, and the paving board can be easily attached and detached, so that the track maintenance by a large multiple tie tamper (MMT) similar to the case of the track of the general part other than the railroad crossing becomes possible. The level crossing pavement member in the level crossing pavement structure using the “Soken-type level crossing pavement plate” and the level crossing pavement member used in the “assembled pavement plate type crossing pavement structure” are hereinafter referred to as “level crossing pavement plate”.

  In the case of the level crossing described above, in particular, in the case of a level crossing where the road crosses obliquely rather than at a right angle to the railroad track (hereinafter referred to as “diagonal crossing”), walking among the roads etc. in the level crossing Part of the level crossing pavement board or the like may also protrude outside the sidewalk used for people's traffic (on the side toward the front or the rear in the direction of the railway track). Such a protruding portion is a portion that is not originally provided for use by pedestrians (hereinafter referred to as “passing improper portion”). This is because when a level crossing pavement plate, etc. is made to exactly match the planar shape of the sidewalk, the shape of the level crossing pavement plate, which is usually a rectangular plate shape (for example, a planar projection shape), becomes various and diverse. Since it becomes manufacture, a manufacturing cost will increase on the contrary. In order to avoid this, the actual situation is that it is necessary to use a pavement board of a general part (for example, the center part of a crossing roadway, etc.) at such a protruding part. It is supposed to protrude. The outside of this improper portion (the side facing either the front or the rear in the direction of the railroad track) is a roadbed of the railroad track or a roadbed between the railroad tracks, and the railroad track side is lowered in a stepped shape.

However, recently, in the above crossing crossing, a passerby who was passing the sidewalk in the railroad crossing with a wheelchair for the physically handicapped accidentally from the improper part that protruded as described above accidentally A wheelchair wheel was removed from the wheelchair. For this reason, means for preventing the recurrence of such an accident is strongly demanded.

FIG. 1 is a top view showing an overall configuration of a level crossing pavement structure according to a first embodiment of the present invention. FIG. 2 is a diagram showing a more detailed configuration of the connecting track near the outer edge in the level crossing pavement structure according to the first embodiment of the present invention. FIG. 2A is an enlarged view of the connecting track near the outer edge. FIG. FIG. 2B is a view for showing a cross-sectional configuration of the uneven portion formed on the upper surface of the inadequate passage portion of the connecting raceway plate near the outer edge, as viewed from the left or the right in FIG. FIG.

  As shown in FIG. 1, the level crossing pavement structure according to the first embodiment of the present invention is a crossing level pavement structure of the above-described oblique crossing, and is a level crossing pavement structure in the form of “joint track”. This level crossing pavement structure 101 includes a roadway 1, a sidewalk 2, a general part connecting track plate 11, and outer edge connecting track plates 12 </ b> A and 12 </ b> B.

  The roadway 1 is a part used for the passage of vehicles (automobiles, bicycles with a motor, etc.) among roads in a level crossing other than a place where the general part connection track plate 11 and the outer periphery connection track plates 12A and 12B are installed. For example, asphalt pavement.

  The sidewalk 2 constitutes a portion used for passage of pedestrians among roads in a level crossing other than a place where the general portion connecting track plate 11 and the outer peripheral connecting track plates 12A and 12B are installed, for example, asphalt It consists of paving. Here, a pedestrian includes a wheelchair for a disabled person in addition to a human being.

  In the level crossing pavement structure 101 of the first embodiment, the outer edge of the roadway which is the left side of FIG. 1 among the outer edge lines of the left and right ends of FIG. 1 which is the track direction (longitudinal direction of the rail R) of the roadway 1. The outside (left side) of the line 3 is a railroad track (for example, a roadbed or a roadbed between tracks). Also, among the roadways 1, among the outer edge lines at the ends in the left-right direction in FIG. 1 that are the track direction (longitudinal direction of the rail R), the line 4 on the right side in FIG. Sidewalk border).

  In addition, among the outer edge lines at the ends in the left-right direction in FIG. 1 that are the track direction (longitudinal direction of the rail R) in the sidewalk 2, the outside (left side) of the sidewalk outer edge line 5 on the right side in FIG. It is a railroad track (for example, a roadbed or a roadbed between tracks).

  As described above, in the railroad crossing pavement structure 101 of the first embodiment, the sidewalk 2 is installed only on one side of the roadway 1 (the right side in FIG. 1).

  Moreover, the upper surface of the general part connection track plate 11 and the outer edge vicinity connection track plates 12A and 12B includes a portion used for passing a vehicle and a portion used for passing a pedestrian. Here, the portion used for the passage of the vehicle is a portion located inside the area on the extension of the roadway 1, that is, inside the area sandwiched between the roadway outer edge line 3 and the roadside boundary line 4. Further, the portion used for the passage of pedestrians is a portion located inside the area that is an extension of the sidewalk 2, that is, inside the area sandwiched between the sidewalk boundary line 4 and the sidewalk outer edge line 5. Here, a pedestrian includes a wheelchair for a disabled person in addition to a human being.

  As shown in FIG. 2, the railroad crossing pavement structure 101 of the first embodiment is located outside the sidewalk 2 on the road in the railroad crossing, on the surface of the outer peripheral connecting track 12A. When a small pedestrian vehicle such as a wheelchair passes, there is a possibility of falling to the railroad track side or wheel-off, and on the improper surface that becomes the surface (upper surface) of the improper portion 22 which is not suitable for passage of a small pedestrian vehicle, It is in the point where the uneven part was formed. 2A, the portion indicated by reference numeral 21 in the articulated track plate 12A in the vicinity of the outer edge is a passage portion and a portion that communicates with the sidewalk 2, and a pedestrian (such as a wheelchair for a disabled person such as a wheelchair). This is a part provided for traffic. FIG. 2A shows the outermost portion of the rail crossing in the longitudinal direction of the rail (the left-right direction in FIGS. 1 and 2) among the eight outer peripheral connecting tracks 12A and 12B in FIG. The left outer edge or the right outer edge) is shown in FIG. Of the eight outer edge connecting track plates 12A and 12B in FIG. 1, the outer edge adjacent to the inner edge of the outermost outer connecting track plate 12A in the longitudinal direction of the rail. The basic structure of the articulated raceway plate 12B is the same as that of the articulated raceway plate 12A except that the area of the improper passing portion 22 is reduced.

  The concavo-convex portion is configured by the protrusions 22a and the grooves 22b being alternately arranged substantially in parallel. The protrusion 22a is a protrusion that extends linearly so as to be substantially parallel to the horizontal direction of FIGS. 1 and 2 which is the extending direction of the railway track (the longitudinal direction of the rail R). Further, the groove 22b is a groove extending linearly so as to be substantially parallel to the horizontal direction in FIGS. 1 and 2 which is the extending direction of the railway track (the longitudinal direction of the rail R).

  As shown in the cross-sectional view of FIG. 2B, a planar portion intermediate between the protrusion 22a and another adjacent protrusion 22a constitutes a groove 22b. Moreover, the wheel W of a wheelchair for a disabled person can be accommodated in the inside of the groove 22b (a portion between the inner wall of the protrusion 22a and the inner wall of another adjacent protrusion 22a). .

  With the configuration as described above, when a wheelchair for a physically handicapped person passes through an improper surface that becomes the surface (upper surface) of the improper portion 22, after riding on a certain protrusion 22a, it falls into the adjacent groove 22b, Repeat this ride and drop. As a result, vibration (with backlash) occurs in the wheelchair. When this vibration (with backlash) occurs, the wheelchair passenger recognizes the abnormality, and that his / her wheelchair has entered the improper part of the railroad crossing. It can be understood that there is a risk of falling to the roadbed or roadbed between tracks). Then, after the wheelchair passenger recognizes this abnormal vibration (with backlash), he or she can voluntarily return to a sidewalk or the like (eg, the passing portion 21 in FIG. 2A) that can be originally passed.

  In the first embodiment described above, the general portion connecting track plate 11 and the outer edge connecting track plates 12A and 12B correspond to the level crossing paving members in the claims. Moreover, the protrusion 22a and the groove | channel 22b comprise the uneven | corrugated | grooved part in a claim.

  Next, a second embodiment of the present invention will be described. FIG. 3 is a diagram showing a more detailed configuration of the outer peripheral connecting track plate in the level crossing pavement structure according to the second embodiment of the present invention, and an uneven portion formed on the upper surface of the improper passing portion of the outer peripheral connecting track plate. FIG.

  As shown in FIG. 3, the feature of the level crossing pavement structure of the second embodiment is that, on the road in the level crossing, the sidewalk (first side) of the surface of the connecting track near the outer edge (see 12 in the first embodiment). (Refer to 2 in the embodiment.) When a small walking vehicle such as a wheelchair for the physically disabled passes through, it may fall to the side of the railway track or derail, and is not suitable for passing a small walking vehicle. The unevenness portion is formed on the improper surface which is the surface (upper surface) of the improper portion 32 which is a place.

  The concavo-convex portion is configured by the protrusions 32a and the grooves 32b being alternately arranged in parallel. The protrusion 32a is a protrusion that extends linearly so as to be substantially parallel to the extending direction of the railroad track (the longitudinal direction of the rail R; see the left-right direction in FIGS. 1 and 2). Moreover, the groove | channel 32b is a groove | channel extended linearly so that it may become substantially parallel to the extending direction (the longitudinal direction of the rail R. Refer the left-right direction of FIG.1 and FIG.2) of a railroad track.

  As shown in the cross-sectional view of FIG. 3, an intermediate planar portion between the protrusion 32 a and another adjacent protrusion 32 a constitutes a groove 32 b. Further, a wheelchair wheel W for a disabled person can be accommodated in the inside of the groove 32b (intermediate portion of the inner wall of the protrusion 32a and another adjacent protrusion 32a).

  Further, one side wall (left side in FIG. 3) of the ridge 32a has a steeply inclined slope that rises from the bottom surface of the groove 32b toward the top at a large angle (steep angle of about 70 to 90 degrees). The vicinity of the top of the protrusion 32a is substantially flat, and the other side wall (the right side in FIG. 3) of the protrusion 32a has a small angle (a gentle angle of about 20 to 50 degrees) from the bottom surface of the groove 32b. It has a sloping slope that rises towards the top.

  With the configuration as described above, when a wheelchair for a physically handicapped person passes through an improper surface that becomes the surface (upper surface) of the improper portion 32, after riding on a certain protrusion 32a, the wheelchair falls into the adjacent groove 32b, Repeat this ride and drop. As a result, vibration (with backlash) occurs in the wheelchair. When this vibration (with backlash) occurs, the wheelchair passenger recognizes the abnormality, and that his / her wheelchair has entered the improper part of the railroad crossing. It can be understood that there is a risk of falling to the roadbed or roadbed between tracks). Then, after the wheelchair passenger recognizes this abnormal vibration (with backlash), he or she can voluntarily return to a sidewalk or the like that can be originally passed.

  Furthermore, the second embodiment has the following operations and effects in addition to the operations and effects similar to those of the first embodiment. That is, when the wheel W of the wheelchair passes from left to right in FIG. 3, it is more difficult to ride on the ridge 32a from the left side than from the right side. It is easier to ride on the ridge 32a from the right side than from the left side. For this reason, it is relatively difficult to enter the improper portion (in the case of FIG. 3, the direction from left to right), and even if it enters the improper portion, it is relatively easy to reverse (see FIG. In the case of 3, it can return in the direction from right to left. This second embodiment is effective when the sidewalks are provided on both sides (both sides) of the roadway (when the direction of travel of each sidewalk is limited to almost one direction) at the railroad crossing. .

  The level crossing pavement structure of the second embodiment is exactly the same as that of the first embodiment with respect to the configuration and operation of the other constituent elements other than the uneven portions.

  In the second embodiment described above, the ridge 32a and the groove 32b constitute an uneven portion in the claims.

  In railways, if any structure is provided near the railroad, it must be constructed outside the building limits. Accordingly, in the first and second embodiments described above, the positions of the vertices of the ridges 22a and 32a need to be lower than the construction limit line of the railway track.

  The present invention is not limited to the above embodiments. The above-described embodiment is an exemplification, and the present invention has the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present embodiment. It is included in the technical scope of the invention.

  For example, in the above-described embodiment, the crossing where the railroad track and the road intersect is described as an example as the target level crossing, but the present invention is not limited to these, and other portions, for example, the railroad track It is good also as a level crossing made into the part where a passage crosses. Further, in the above embodiment, as an example of a level crossing that has been described, an oblique crossing in which a road or the like crosses obliquely rather than at a substantially right angle with respect to a railroad track has been described as an example. However, the present invention is not limited to this, and other level crossings such as a crossing at which a road or the like intersects the railway track at a substantially right angle may be used as a target level crossing.

  Further, in the above embodiment, as the level crossing pavement structure provided with the uneven portion, the connection track has been described as an example, but the present invention is not limited to these, and the level crossing pavement structure of other configurations, for example, Soken type Level crossing pavement structure using level crossing pavement plate, assembly type pavement plate type crossing pavement structure, flooring type level crossing pavement structure using wooden flooring, flooring type crossing pavement structure using paving stone, flooring type crossing pavement structure using wooden sleepers You may apply. In these cases, in the floor covering type paving structure using a wooden floor board, the floor board corresponds to the level crossing paving member in the claims. Moreover, in the floor covering type crossing pavement structure using a paving stone, the paving stone corresponds to the level crossing paving member in the claims. Moreover, in the flooring type level crossing pavement structure using a wood sleeper, the wood sleeper corresponds to the level crossing pavement member in the claims.

  Further, in the above embodiment, as an example of a level crossing pavement structure for providing uneven portions, wheelchairs for physically handicapped persons have been described as examples, but the present invention is not limited to these, and other things, for example, A walking assistance vehicle, a shopping cart, or a child's vehicle may be targeted. In the specification of the present application, the wheelchair for the physically handicapped person, the walking auxiliary vehicle, the shopping cart, or the child's vehicle is referred to as a “small vehicle for walking”.

  Moreover, in the said Example, although demonstrated as an example the location which becomes the outer side (railroad track side) of a sidewalk as a location of a level crossing pavement member of a level crossing pavement structure which provides an uneven part, this invention is in this example. It is not limited, It is good also considering the other location, for example, the location which becomes the outer side (railroad track side) of a roadside belt as an applicable location. In the above embodiment, a crossing in which a sidewalk is provided only on one side of the roadway is taken as an example. However, the present invention is not limited to this example, and other crossings, for example, both sides (both sides of the roadway) It can also be applied to railroad crossings with sidewalks on the side.

  Further, as the concavo-convex portion, a configuration other than a combination of a ridge and a groove extending linearly in the rail longitudinal direction and substantially parallel to each other as in each of the above embodiments may be used. For example, the concavo-convex portion is configured by linearly extending ridges and linearly extending grooves alternately arranged substantially in parallel, and the longitudinal direction of the ridges and grooves is the direction of travel of a small vehicle for walking within a railroad crossing. You may set so that it may become substantially right angle with respect to (the diagonal direction substantially parallel to the sidewalk boundary line 4 or the sidewalk outer edge line 5 in FIG. 1).

  Or, the surface of the uneven part where protrusions having a substantially hemispherical shape are arranged in a scattered manner, that is, the so-called "braille block" for the visually impaired provided on the sidewalk, etc., where the round protrusions are arranged substantially uniformly. It is good also as an uneven | corrugated | grooved part which resembles this shape.

  Or the uneven | corrugated | grooved part of another structure may be sufficient. In this case, it is necessary to make the position of the apex of the convex part be lower than the construction limit line of the railway track.

  The present invention can also be realized with other configurations. For example, a plate-like or sheet-like member having the concavo-convex portion as described above (hereinafter referred to as “road surface member for level crossing pavement”) is attached to the surface of the inadequate portion of the existing level crossing pavement member. It may be. In this case, RC (steel reinforced concrete), hard plastic, cast iron, or the like can be used as a material for the road surface member for level crossings. In addition, as a method of attaching this road surface member for level crossing pavement to the surface of the improper part of the existing level crossing pavement member, adhesion by adhesive, adhesion by cement mortar, etc., mechanical joining by bolts, etc. can be used. is there. In addition, as a time of attaching this road surface member for level crossing pavement to the surface of the improper part of the existing level crossing pavement member, it may be before the installation of the level crossing pavement member, or during the installation of the level crossing pavement member, Or you may attach after installation of a level crossing pavement member. Even in the case of this level crossing pavement road member, the position of the apex of the convex part after installation needs to be lower than the construction limit line of the railway track.

  The present invention can be implemented by a railway operator who operates a railway, and can also be implemented by a construction industry that constructs a railway track or a company that maintains a railway track, and can be used in these industries. Further, the railroad crossing pavement member can be manufactured in the manufacturing industry of concrete secondary products, railway materials and the like, and can be used in these industries.
