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 that is installed in a level crossing and forms a road surface such as a road, and a level crossing pavement member is installed in a level crossing More particularly, the present invention relates to a wheelchair slip-off prevention type crossing pavement structure, a wheelchair slip-off prevention level crossing pavement member, and a level crossing pavement method that can prevent a wheelchair from slipping off.

  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, this 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 pavement structure using this type of level crossing pavement plate is not shown, but it is a plate-shaped member made of reinforced concrete (RC), prestressed concrete (PC), etc. 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-like 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. Moreover, what is comprised as various members, such as concrete, synthetic resin, resin concrete, or a rubber-type material, is known as a laying member for level crossings. The level crossing pavement member in the level crossing pavement structure using the `` Soken-type level crossing pavement plate '', the level crossing pavement member used in the `` assembled pavement plate type crossing pavement structure '', and the laying member for the level crossing pavement composed of various materials, It is called "railway pavement board".

  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 toward the front or the rear in the direction of the railroad track) serves as the roadbed of the railroad track or the roadbed between the railroad tracks, and the railroad track side is lowered in a stepped shape.

However, recently, in the above-mentioned oblique 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 The wheelchair's wheel was removed from the wheelchair, etc., and before the rescue was made in time, a painful personal injury that resulted in contact with the train that entered the railroad crossing resulted in death. For this reason, means for preventing the recurrence of such an accident is strongly demanded.

FIG. 2B is an enlarged cross-sectional view of the upper portion of the wheelchair fall-off prevention end block 15A in FIG. FIG. 2C is a top view of FIG. 2A viewed from above.

  As shown in FIG. 1, a wheelchair fall prevention type crossing pavement structure 101 according to the first embodiment of the present invention is a crossing pavement structure of the above-described oblique crossing, and is a crossing pavement structure in the form of “joint track”. is there. The wheelchair fall-off prevention type railroad crossing pavement structure 101 is configured to include a roadway 1, a left sidewalk 2L and a right sidewalk 2R, a general part connecting track plate 11, and outer edge connecting track plates 12A and 12B. .

  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 sidewalks 2L and 2R constitute a portion used for passage of pedestrians among the roads within the level crossing other than the place where the general part connecting track plates 11 and the outer peripheral connecting track plates 12A and 12B are installed, for example, It consists of asphalt pavement. Here, a pedestrian includes a wheelchair for a disabled person in addition to a human being.

  In the wheelchair fall prevention type railroad crossing pavement structure 101 of the first embodiment, among the outer edge lines of the left and right end portions in FIG. 1 which is the track direction (longitudinal direction of the rail R) of the roadway 1 in FIG. The line 4L on the left side is a boundary line (car sidewalk boundary line) with the sidewalk 2L. Further, of the roadway 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 </ b> R on the right side in FIG. Sidewalk border).

  In addition, the outside (left side) of the sidewalk outer edge line 5L is a railroad track (for example, a roadbed or a roadbed between tracks). Similarly, the outside (right side) of the sidewalk outer edge line 5R is a railroad track (for example, a roadbed or a roadbed between tracks).

  As described above, in the wheelchair fall prevention type railroad crossing pavement structure 101 of the first embodiment, the sidewalk 2L and the sidewalk 2R are installed on both the left and right sides of the roadway 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 traffic of the vehicle is a portion located inside the region on the extension of the roadway 1, that is, inside the region sandwiched between the sidewalk boundary line 4L and the sidewalk boundary line 4R. .

  In addition, a part provided for pedestrian traffic is an area on the extension of the sidewalk 2L, that is, a part located inside the area between the sidewalk boundary line 4L and the sidewalk outer edge line 5L, and the sidewalk It is a portion located inside the region that is an extension of 2R, that is, inside the region sandwiched between the sidewalk boundary line 4R and the sidewalk outer edge line 5R. Here, a pedestrian includes a wheelchair for a disabled person in addition to a human being. Further, in this case, the sidewalk is a right-hand traffic, and on the sidewalk 2L, a pedestrian passes in a direction from the upper right to the lower left in FIG. On the sidewalk 2R, pedestrians pass in the direction from the lower left to the upper right in FIG.

  As shown in FIG. 2, the wheelchair fall-off prevention level crossing pavement structure 101 of the first embodiment is located outside the sidewalk 2L or 2R on the road in the level crossing, and is a wheelchair such as a wheelchair for the disabled. If the vehicle passes, there is a possibility of falling to the railroad track side or wheel-out. Near the outer edge of the place that is not suitable for wheelchair traffic (unsuitable part), on the side (side part) of the connecting track plate 12A or 12B, to prevent wheelchair slipping End blocks 15A, 15B, 15C, and 15D are installed, and uneven portions (for example, protrusions 31a and 31b and grooves 32a and 32b) described later are formed on the upper surface of the wheelchair-preventing end block (for example, 15A) to prevent slipping. The wall 33 is provided.

  Hereinafter, the wheelchair fall-off prevention end block 15A will be described. The other wheelchair fall-preventing end blocks 15B to 15D have the same basic configuration except that the installation positions in the railroad crossing are slightly different.

  The concavo-convex part is configured by alternately arranging the ridges 31a and grooves 32a, and the ridges 31b and grooves 32b in parallel. The protrusions 31a and 31b are protrusions that extend in a straight line so as to be substantially parallel to the horizontal direction of FIGS. 1 and 2 that is the extending direction of the railway track (the longitudinal direction of the rail R). Further, the grooves 32a and 32b are grooves extending 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, a fallout prevention wall 33 is formed on the first outer edge E1 (see FIG. 2C), which is the outer edge of the wheelchair fallout prevention end block 15A. The anti-fall-off wall 33 is a portion protruding in a substantially sidewall shape vertically upward. These concavo-convex portions (for example, the protrusions 31a and 31b) and the top portion of the anti-fall-off wall 33 are outside the lower limit of the building limit at this location, and do not hinder the railway business. Yes.

  As shown in the enlarged cross-sectional view of FIG. 2B, a planar portion intermediate between the ridge 31a and another adjacent ridge 31b constitutes a groove 32a. Further, a flat portion in the middle between the ridge 31b and the anti-fall-off wall 33 on the outer edge constitutes the groove 32b. Further, the inside of these grooves 32a (the portion between the side surface S11 of the ridge 31a and the side surface S21 of another adjacent ridge 31b) or the inside of the groove 32b (the side surface S12 of the ridge 31b and the slip-off). A front wheel W (see FIG. 3) of a wheelchair for a physically handicapped person can be accommodated in a portion between the side wall S22 of the prevention wall 33). Of the above-described side surfaces, S11 and S12 are inclined, and S21 and S22 are substantially vertical surfaces.

  Next, the operation of the wheelchair fall-off prevention type railroad crossing pavement structure 101 according to the first embodiment will be described with reference to FIG. With the configuration as described above, when the front wheel W of the wheelchair for the physically disabled passes through the surface (upper surface) of the anti-fall-off block 15A, as shown in FIG. 3A, the slope of the first protrusion 31a After sliding down the shaped side surface S11, it falls into the adjacent groove 32a. Next, it rides on the adjacent ridge 31b. Then, after sliding down the slope-shaped side surface S12 of the ridge 31b, it falls into the adjacent groove | channel 32b. In this way, the wheelchair front wheel W (the same applies to the rear wheel of the wheelchair not shown) repeats riding on the ridge and dropping into the groove. 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 section of the railroad crossing, and if it continues to pass through the improper section, the railway track section ( It can be understood that there is a risk of falling to the roadbed or roadbed between tracks).

Here, the vertical height difference Δh between the top (projection 31a or 31b) and the bottom (groove 32a or 32b) of the concavo-convex part is required to have the function of generating the vibration described above in the front wheel W of the wheelchair. The For this reason, the applicants have found that the following values are preferable as the value of Δh as a result of experiments and the like. That is, if the diameter of the front wheel of the wheelchair is D,
0.05D ≦ Δh ≦ 0.4D
It is preferable to be set to a value in the range. The diameter D of the front wheel of a wheelchair is generally set to 6 inches (152.4 millimeters). In such a case, the height difference Δh of the concavo-convex portion is preferably set in a range of 8 millimeters ≦ Δh ≦ 61 millimeters.

In addition, since the front wheel W of the wheelchair is required to have the function of generating vibration as described above, the width B of the recess (groove 32a or 32b) of the concavo-convex part can accommodate the front wheel of the wheelchair and can be noticed. The value needs to be short enough to generate vibration. For this reason, the applicants have found that the following values are preferable as the numerical value of B as a result of experiments and the like. That is, if the diameter of the front wheel of the wheelchair is D,
0.05D ≦ B ≦ 4.0D
It is preferable to be set to a value in the range. The diameter D of the front wheel of a wheelchair is generally set to 6 inches (152.4 millimeters). In such a case, the width B of the concave portion of the concave and convex portion is preferably set in a range of 8 millimeters ≦ Δh ≦ 610 millimeters.

  Then, after the wheelchair passenger recognizes this abnormal vibration (with backlash), he or she can voluntarily return to a sidewalk or the like (eg, 2L or 2R in FIG. 1) that can be originally passed. At this time, since the side surface S11 of the ridge 31a and the side surface S12 of the ridge 31b are respectively inclined, the wheelchair is easily retracted. The slope S11 does not have to start from the bottom of the groove 32a. After rising from the bottom of the groove 32a into a substantially vertical surface, the slope starts from the middle of the substantially vertical surface and goes toward the top of the ridge 31a. You may comprise. Similarly, the slope S12 does not have to be started from the bottom of the groove 32b. After rising from the bottom of the groove 32b into a substantially vertical surface, the slope is started from the middle of the substantially vertical surface toward the top of the ridge 31b. You may comprise as follows.

Then, the wheelchair front wheel W is finally restrained by the anti-falling wall 33 standing upright on the outer edge, as shown in FIG. 3 (B), and the wheelchair front wheel W falls or falls off the anti-falling end block 15A. Doing so has been blocked. Here, the height H in the vertical direction from the bottom of the concavo-convex portion of the fall-off prevention wall 33 (the bottom of the groove 32b) is required to have a function of blocking the front wheel of the wheelchair. For this reason, the applicants have found that the following values are preferable as the numerical value of H as a result of experiments and the like. That is, if the diameter of the front wheel of the wheelchair is D,
H ≧ 0.1D
It is preferable to set the value to be. The diameter D of the front wheel of a wheelchair is generally set to 6 inches (152.4 millimeters). In such a case, it is preferable to set the height H of the anti-fall-off wall 33 to at least 15 millimeters or more.

  In the first embodiment described above, the wheelchair slip-off preventing end blocks 15A to 15D correspond to wheelchair slip-off preventing level crossing pavement members in the claims. Further, the protrusions 31a and 31b and the grooves 32a and 32b constitute an uneven portion in the claims.

  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 wheelchair fall-off type crossing pavement structure provided with the uneven portion, the articulated track has been described as an example, but the present invention is not limited to these, and the crossing pavement structure of other configurations , For example, level crossing pavement structure using Soken-type 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 using wood sleeper You may apply to a type crossing pavement structure. 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.

  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 wheelchair fall prevention type level crossing pavement structure which provides an uneven part, this invention Is not limited to this example, and other locations, for example, locations on the outside of the roadside belt (railway line side) may be used as the corresponding locations. 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 constituted 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 the wheelchair within the crossing (see FIG. 1 may be set to be substantially perpendicular to the sidewalk boundary line 4L or the like in FIG. 1 or an oblique direction substantially parallel to the sidewalk outer edge line 5L or the like.

  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, the fall-out prevention wall is not only provided at the first outer edge E1 (see FIG. 2C) of the outer edges of the improper passage portion, but is further provided at the second outer edge that is substantially perpendicular to the extending direction of the railway track.
