Description

The present disclosure relates to a track-based transportation system and a method of constructing a track-based transportation system.

As a new means of transportation other than buses and railroads, a track-based transportation system that travels on a track by running wheels equipped with rubber tires is known.

In such a track-based transportation system, in order to effectively utilize the space on the existing road, the track on which the vehicle travels is formed as an elevated track arranged on the viaduct. For example, in Patent Document 1, orbits are formed on a plurality of columns arranged at intervals on a median strip. The orbit is formed by a pair of main girder beams fixed on a strut and a plurality of connected beams connecting the pair of main girder beams. Further, in such an elevated track, stations are arranged on the road as elevated stations.

In such an elevated track, it is necessary to provide a plurality of viaducts or bridge girders on the viaducts, which may increase the construction cost. Therefore, if the track is elevated over the entire line, the laying cost will increase. On the other hand, if the track on which the vehicle of the track system transportation system travels and the lane in which the vehicle travels are installed side by side on the ground surface instead of the elevated track, the track and lane will be compared with the case where the elevated track is used. The combined road width becomes wider. In particular, at stations where users of track-based transportation systems get on and off vehicles, it is necessary to provide a platform for users to stand by along the track, which further increases the required road width. However, when there are existing buildings or the like on both sides in the width direction of the road, it may be difficult to widen the road width in order to provide a platform.

A track portion including a slope section connecting the road traveling section and the station installation section is provided, and the station installation section is below the vertical direction with respect to the lane and in the width direction with respect to the track road surface. It has a platform arranged in an underground space portion formed at a position adjacent to each other, and in the track portion, only the track road surface of the station installation section is located below the lane in the vertical direction.

The construction method of the track-based transportation system according to the present disclosure is the construction method of the track-based transportation system, in which the ground is excavated to form only the underground space portion and the platform is formed in the underground space portion.

In the road traveling section 3A, the track road surface 32 extends at a height corresponding to the lane 21 of the road portion 2. That is, in the road traveling section 3A, the track road surface 32 is arranged at substantially the same height as the lane 21. The substantially same height is not limited to the case where the track surface 32 and the road surface of the lane 21 are at the same height. It includes differences in road surface height.

As shown in FIGS. 1, 3 and 4, the station installation section 3B is a section provided with a station 5 for passengers to get on and off the vehicle 4. That is, in the station installation section 3B, equipment capable of stopping the vehicle 4 is provided. In the station installation section 3B, the track road surface 32 extends below the lane 21 in the vertical direction Dv. Specifically, in the station installation section 3B, the track road surface 32 is arranged in the underground portion Gb located below the ground surface Gf in the vertical direction Dv. In the present embodiment, the station installation section 3B has a recess 33 recessed downward with respect to the ground surface Gf. The recess 33 has a plurality of openings 331 that open upward between the plurality of road portions 2. In the station installation section 3B, the track road surface 32 is arranged on the bottom surface of the recess 33. In the track portion 3, only the traveling surface 31 and the track road surface 32 of the station installation section 3B are located below the lane 21 in the vertical direction Dv.

Further, as shown in FIGS. 1 and 3, in the station installation section 3B, wall portions 52 rising upward in the vertical direction Dv are provided on both sides of the opening 331 in the width direction Dw. The station installation section 3B has a roof 53 that covers above the track road surface 32. The roof 53 of the present embodiment covers a part of the openings 331. It is preferable that the roof 53 has a structure in which at least a part of the roof 53 is made of a light-transmitting material such as glass and has high daylighting property.

As shown in FIG. 4, the gradient section 3C is provided on both sides of the extension direction Da with respect to the station installation section 3B. The gradient section 3C is a section connecting the road traveling section 3A and the station installation section 3B. In the slope section 3C, the traveling surface 31 and the track road surface 32 are inclined and extended.

(Station configuration)
As shown in FIGS. 1 and 3, the station 5 provided in the station installation section 3B has a platform 55. The platform 55 is formed in the underground space portion 56S. The underground space portion 56S is formed at a position below the vertical Dv with respect to the lane 21 and adjacent to the track road surface 32 in the width direction Dw. That is, the underground space portion 56S is formed so as to project from the recess 33 toward at least one of the width direction Dw (both sides of the width direction Dw in the present embodiment) toward the lower side of the lane 21. The platform 55 extends in the stretching direction Da. The platform 55 may be provided with ancillary equipment (not shown) such as a ticket gate, a station staff room, and a shop.

The platform 55 is formed by, for example, a precast skeleton 56 made of reinforced concrete having a C-shaped cross section. By making the precast skeleton 56 made of precast concrete, the construction period at the site can be shortened. The precast skeleton 56 includes a bottom plate portion 561, an upper plate portion 562, a first side portion support portion 563, and a second side portion support portion 564. The underground space portion 56S is formed by being surrounded by a bottom plate portion 561, an upper plate portion 562, a first side portion support portion 563, and a second side portion support portion 564. The precast skeleton 56 is housed in the underground space 56S. A plurality of precast skeletons 56 are arranged side by side in the stretching direction Da.

The bottom plate portion 561 is fixed on the bottom surface of the underground space portion 56S. The bottom plate portion 561 constitutes a floor surface on which passengers walk on the platform 55.

The upper plate portion 562 is arranged at intervals above the vertical Dv with respect to the bottom plate portion 561. The upper plate portion 562 is supported by the first side portion support portion 563 and the second side portion support portion 564 with respect to the bottom plate portion 561. The lane 21 formed at a position overlapping the region where the underground space portion 56S is formed when viewed from the vertical direction Dv is formed on the upper plate portion 562. That is, the upper plate portion 562 supports the lane 21 from below the vertical Dv.

The first side support portion 563 is arranged at a position close to the track road surface 32 inside the width direction Dw with respect to the bottom plate portion 561 and the upper plate portion 562. The first side support portion 563 is a plurality of pillars arranged at intervals in the stretching direction Da. The second side support portion 564 is provided outside the width direction Dw with respect to the bottom plate portion 561 and the top plate portion 562. The second side support portion 564 has a wall shape and has an opening in a portion communicating with the passage portion 60 described later.

Further, as shown in FIGS. 1 to 3, the track portion 3 further has a passage portion 60. The aisle 60 allows passengers to access the platform 55 from the sidewalk 6. The passage portion 60 is connected to the road portion 2 and the track portion 3 with the sidewalk 6 on the ground surface Gf outside the width direction Dw. The passage portion 60 is connected to the platform 55 on the outside of the width direction Dw (the side opposite to the position where the track road surface 32 is arranged). The passage portion 60 includes a hoistway 62 and a connecting passage 63. The hoistway 62 is connected to the sidewalk 6. The hoistway 62 includes stairs 621, an elevator 622, an escalator, a ramp (not shown), and the like. The connecting passage 63 extends in the width direction Dw and connects the hoistway 62 and the platform 55.

(Construction method of track-based transportation system)
Next, the construction method of the track-based transportation system 1 as described above will be described. In the present embodiment, the construction method of the track system transportation system 1 is applied to the case where the traveling surface 31 and the track road surface 32 are formed later in the state where the lane 21 is already formed. As shown in FIG. 5, the construction method S1 of the track-based transportation system 1 in the present embodiment forms a track with a step S11 for forming a temporary road, a step S12 for forming a platform, and a step S13 for forming a lane. Step S14 and

(Process to set up a temporary road)
In the step S11 of providing the temporary road, as shown in FIGS. 6 and 7, the passage of automobiles in the area corresponding to the station installation section 3B where the station 5 is formed below the lane 21 is blocked. After that, a temporary road 70 is provided in the area above the vertical direction Dv with respect to the area where the track road surface 32 is planned to be arranged in the station installation section 3B and the slope section 3C. Here, in the present embodiment, the platform 55 is formed in the first region A1 on both outer sides of the track road surface 32 in the width direction Dw in the station installation section 3B. That is, the platform 55 is formed below the vertical Dv with respect to the first lane 21A. Therefore, as shown in FIG. 7, the temporary road 70 is laid between the first lanes 21A in the width direction Dw. At this time, the recess 33 on which the track road surface 32 is to be arranged has not yet been formed. The temporary road 70 is connected to the first lane 21A before and after the first region A1 in the extension direction Da. As a result, the vehicle traveling in the first lane 21A can travel by bypassing the first region A1 by moving from the first lane 21A to the temporary road 70 and returning from the temporary road 70 to the first lane 21A. .. Further, the automobile traveling in the second lane 21B can travel in the second lane 21B arranged outside the width direction Dw with respect to the first region A1 without being affected by anything.

(Process of forming a platform)
In the step of forming the platform S12, as shown in FIG. 7, after the temporary road 70 is formed, the ground G is excavated to form the platform 55. In the step S12 of forming the platform, first, the ground G corresponding to the first region A1 where the platform 55 is installed is excavated by an open-cut method so as to avoid the temporary road 70. As a result, only the underground space portion 56S corresponding to the length of the platform 55 in the extending direction Da is formed at a position at a predetermined depth from the ground surface Gf. After that, a plurality of precast skeletons 56 are arranged in the underground space portion 56S. As a result, the platform 55 is formed in the underground space portion 56S.

(Process of forming a lane)
In the lane forming step S13, as shown in FIG. 8, after the platform 55 is formed, the first lane 21A is formed above the underground space portion 56S. Specifically, first, wall portions 52 are formed on both sides in the width direction Dw with respect to the position where the opening 331 of the recess 33 is formed. That is, the wall portions 52 are formed on both sides of the temporary road 70 in the width direction Dw. As a result, in the lane forming step S13, the construction can proceed while ensuring the safety of the automobile passing through the lane 21. After that, a roadbed and a pavement material are provided on the upper plate portion 562 above the vertical Dv with respect to the platform 55. As a result, a part of the first lane 21A is laid so that the position in the width direction overlaps with the temporary road 70. After that, the use of the temporary road 70 will be stopped. As a result, the automobile traveling on the road portion 2 can pass through the first lane 21A as it is.

(Process of forming an orbit)
In the step S14 of forming the track, after forming the lane 21, the traveling surface 31 and the track road surface 32 of the station installation section 3B and the slope section 3C are formed. Specifically, in the step S14 of forming the track, the ground G is excavated at a position adjacent to the formed first lane 21A in the width direction Dw to form the traveling surface 31 and the track road surface 32. First, the temporary road 70 is removed. Further, as shown in FIG. 9, the ground G in the region sandwiched between the first lane 21A in the width direction Dw corresponding to the station installation section 3B is excavated by the excavation method. As a result, the recess 33 of the station installation section 3B is formed. After that, as shown in FIG. 3, the track road surface 32 is formed on the bottom surface of the recess 33. On the track road surface 32, the traveling surface 31 is formed so as to project upward in the vertical direction Dv.

Further, as shown in FIG. 4, in the slope section 3C, an inclined surface 34 extending upward from the recess 33 toward the road traveling section 3A on both sides in the extending direction Da is formed. After that, the traveling surface 31 and the track road surface 32 are laid on the inclined surface 34 of the slope section 3C, and are connected to the traveling surface 31 and the track road surface 32 of the station installation section 3B and the road traveling section 3A. In this way, the ground G is excavated inside (side) of the width direction Dw with respect to the first lane 21A, and the station installation section 3B and the slope section 3C are provided.

Further, a hoistway 62 is formed on the sidewalk 6, and a connecting passage 63 is provided between the hoistway 62 and the underground space portion 56S. Specifically, the ground G in the area where the hoistway 62 is formed on the sidewalk 6 is excavated by the excavation method. After that, the ground G is excavated by the tunnel method so as to connect the area where the excavated hoistway 62 is formed and the platform 55. As a result, the hoistway 62 and the connecting passage 63 are formed. Further, a roof 53 covering the upper part of the track road surface 32 is installed in the station installation section 3B. In this way, the track-based transportation system 1 is constructed.

(Action effect)
In the track system transportation system 1 having the above configuration, the platform 55 is formed at a position below the vertical Dv with respect to the lane 21 and adjacent to the track road surface 32 in the width direction Dw in the station installation section 3B of the track section 3. It is formed in the underground space portion 56S. As a result, it is not necessary to provide the platform 55 side by side with the road portion 2 on the ground surface Gf in the width direction Dw. Therefore, the platform 55 can be provided while suppressing the widening of the road width including the road portion 2.

Further, a passage portion 60 accessible to the platform 55 is formed so as to be connected to the ground surface Gf by a sidewalk 6 outside the width direction Dw with respect to the lane 21. As a result, passengers can enter the platform 55 from the sidewalk 6 via the aisle portion 60 and get on and off the vehicle 4. Therefore, passengers can access the platform 55 without crossing the lane 21. As a result, it is possible to improve the safety and prevent the traffic of the automobile on the road portion 2 from being obstructed.

Further, the station installation section 3B is formed so as to be recessed downward with respect to the ground surface Gf in the road portion 2 and open between a plurality of lanes 21. As a result, the station installation section 3B can be formed by the open-cut method, and the construction can be performed efficiently and at low cost.

Further, the track road surface 32 is arranged in the recess 33 recessed with respect to the ground surface Gf, so that the upper part of the track road surface 32 is opened. On the other hand, in the station installation section 3B, the roof 53 is arranged so as to cover the upper part of the track road surface 32. Therefore, in the station installation section 3B in which the platform 55 is arranged on the side of the track road surface 32 in the width direction Dw, it is possible to prevent rain or the like from blowing into the platform 55 from above the track road surface 32. Further, it is possible to prevent a falling object from the lane 21 from falling on the track road surface 32 of the station installation section 3B.

According to the construction method of the track-based transportation system 1 described above, it is possible to construct the track-based transportation system 1 in which the platform 55 can be provided while suppressing the road width from widening. Further, the underground space portion 56S and the recess 33 can be formed from the ground surface Gf by an open-cut method. Therefore, the station installation section 3B and the slope section 3C of the track portion 3 can be formed efficiently and at low cost.

Further, in the step S12 of forming the platform 55, the temporary road 70 is formed in the region above the vertical Dv with respect to the region where the track road surface 32 is planned to be arranged in the station installation section 3B and the slope section 3C. As a result, the automobile can be diverted to the temporary road 70 during the construction of forming the underground space portion 56S and the platform 55. As a result, it is possible to efficiently construct the track-based transportation system 1 by suppressing the construction area from obstructing the traffic of the automobile passing through the lane 21.

Further, after forming the platform 55, after forming the first lane 21A above the platform 55, a temporary road is used for construction to form a recess 33 and a track road surface 32 by passing an automobile through the first lane 21A. Even if the 70 is broken, the passage of the car will not be obstructed. As a result, while laying the station installation section 3B and the slope section 3C, the construction can be efficiently performed without obstructing the traffic of automobiles.
