Description

  The present invention relates to a road surface drainage that integrally constitutes a vertical wall on the road surface side of a surveillance passage for monitoring inside a tunnel provided at the side of a tunnel wall on the road side in a tunnel such as a carved tunnel or a mountain tunnel for an automobile road. Precast waterway block, especially a precast that has a rectangular waterway that integrally forms a vertical wall on the road surface side of the roadway between the supervisory road and the roadway between the supervisory road and the roadway surface The present invention relates to a tunnel structure having a water channel block (hereinafter simply referred to as “water channel block”).

  Conventionally, on the road side of a motorway in a tunnel such as an open-cut tunnel or a mountain tunnel for a motorway, spring water in the tunnel, rainwater brought along with the car during rain, oil or chemicals leaked in an accident In order to drain washing water after processing such as the above, water spraying during road surface cleaning, etc. from the road surface of a motor vehicle, a water channel block having a circular water channel inside is laid. In addition to these roadside waterway blocks, in order to monitor the condition of the tunnel regularly on the side wall of the tunnel wall of the motorway in the tunnel, and to check whether reinforcement work, repair work or improvement work is necessary In addition, there is a supervisor passage through which a supervisor passes along the side wall of the tunnel side wall, which is about 1 m higher than the road surface of the motorway.

  For example, in the construction of a mountain tunnel for an automobile road, a so-called invert is provided at the lower part of the road surface of the automobile road above the lower edge of the arch constituting the ceiling as a foundation. It was necessary to excavate the lower part of the tunnel to the depth of the invert.

  By the way, as described above, the conventional circular shape is installed between the side of the automobile road surface 3a in the automobile tunnel 1 and the supervisor passage 4 raised from the automobile road surface 3a provided at the side of the tunnel side wall 1b. The height of the side wall 7c of the water channel block 7 of the water channel 7a is larger than the diameter of the circular water channel 7a inside. For this reason, as shown on the right side of FIG. 6, the depth of the lower portion from the road surface 3 a is increased, and the lower corner portion of the side wall 7 c of the water channel block 7 is connected to the invert 6 at the lower portion of the foundation portion 1 a of the tunnel 1. It was necessary to overlap and not interfere with each other. For this reason, it is necessary to extend the tunnel side wall 1b downward and deepen the position of the invert 6. However, when the position of the invert 6 is lowered, the tunnel excavation becomes deeper, and there is a problem that the cost is increased.

  Therefore, in order to compensate for this drawback, a retaining wall structure of a supervisor channel in which a circular water channel is inserted into a retaining wall of a supervisor channel, that is, a vertical wall has been proposed (for example, see Patent Document 1). However, the structure in which this circular water channel is inserted into the retaining wall of the observer passage is said to reduce the tunnel cross section by the amount of the insertion, but management such as repairing the water channel and cleaning the interior of the water channel It was not easy to do.

  Furthermore, when constructing the road surface of an automobile road in a tunnel, when concrete pavement is laid, it is carried out by mechanization by the set foam method or slip method. The side wall or the side wall of the circular water channel block is used as a mold, and a rail is provided on the side circular water channel block or on the side mold. Concrete pavement or asphalt pavement is put into the inside. Also, in the slip method, the device itself has a movable mold, and while running a self-propelled slip device consisting of an endless track on both sides of this movable mold, raw concrete is poured into the movable mold in order to pave the concrete pavement. Do. However, these devices have an overhanging portion on the side of the device, and this overhanging portion comes into contact with the vertical wall of the surveillance passage on the road surface side, for example, so it is difficult to cover the entire road width. Therefore, it is difficult to apply these methods as they are.

JP 2002-327600 A

  The problem to be solved by the present invention is the construction of a tunnel for an automobile road, that is, the construction of a monitoring passage for the side wall of the tunnel in the tunnel and a drainage waterway for the road surface along the passage of the surveillance road and the construction of a paved surface of the automobile road. In this case, by providing a precast waterway block that integrates the drainage waterway and the vertical wall, in the conventional method, after the tunnel lining is completed, the installation of the circular waterway, the concrete of the foundation of the vertical wall of the observer passage In the present invention, it is possible to realize the speeding up of construction and cost reduction by simplifying the process that required three steps of placing and installing the vertical wall of the supervisor passage into one step of installing the precast concrete channel block. In addition, by devising the cross-sectional shape of the drainage waterway, the position of the foundation in the tunnel is increased and the tunnel height from the foundation is lowered, so that the tunnel digging depth is reduced. In the installation work and pavement construction of pipe facilities such as cables such as communication lines and power lines and water supply pipes installed in the lower part of the supervisor's passage In addition, it was possible to construct the roadway and the road surface of the supervisor, which was constructed by significantly reducing the construction cost and construction time of the entire tunnel by improving the convenience of using the paving machine with the set form device and slip form device in the road surface paving work It is to provide a tunnel structure for an automobile road having a drainage channel.

The means of the present invention for solving the above-mentioned problems is that in the invention of claim 1, the vehicle has a road surface at the center, a road surface drainage channel at the road surface side, and between the road surface drainage channel and the tunnel side wall. Means in a tunnel structure for a motorway having a supervisor passage. In this means, the lateral width of the water channel block having a rectangular water channel having a horizontally long transverse cross section is set to the lateral width of the water channel block having a circular water channel having the same water flow amount as that of the rectangular water channel. In comparison, the channel block is formed wider by lowering the height . Further, a plurality of the wide water channel blocks are connected to the road surface side of the automobile road adjacent to the monitoring passage on the side wall of the tunnel to form a drainage water channel, and the side wall on the monitoring channel side of the water channel block is connected to the water channel. It is a tunnel structure comprising a supervisory passage of a tunnel for a motorway and a drainage waterway for a road surface, characterized by extending vertically above the top wall of the block and forming a vertical wall on the side of the motorway of the supervisory passage. .

  In the invention of claim 2, the channel block having the rectangular water channel is formed by separating a plurality of strip-shaped drainage ports for taking in road surface drainage from the upper surface wall to the rectangular water channel in the longitudinal direction of the upper surface wall. 2. A tunnel structure comprising a monitoring road for a tunnel for an automobile road and a water drainage for a road surface, wherein the upper surface wall is disposed and integrated.

  In the above invention, the lateral width of the water channel block having the rectangular water channel in the lateral direction is composed of a horizontally long rectangular surface having a total wall thickness of 750 mm, for example, 150 mm of the wall thickness of the vertical wall and 600 mm of the upper surface width of the water channel portion. As a thing, the width of the water channel block can be reduced by an amount corresponding to the enlarged width because the horizontal width is larger than the horizontal width of the water channel block having a circular water channel through which the same amount of water flows. As a result, the base portion of the tunnel can be raised and positioned, so by applying the water channel block having the rectangular water channel of the present invention, the space below the road pavement surface can also be used for terrain. You can build a tunnel. In addition, while the height of the tunnel above the road pavement is the same as before, the height from the foundation of the tunnel can be lowered, so the material and construction costs for excavation and construction of the tunnel itself are significant. Reduction can be achieved.

  In this water channel block, a plurality of water inlets, for example, 40 mm × 100 mm in size for taking in road surface drainage of automobile roads, are arranged in the short direction of the water channel block at intervals of, for example, 250 mm. The upper surface wall is an integrated wall body. In view of this, it has a high design load capable of withstanding the pressure from above the upper surface wall of the water channel block, and has a sufficiently large area capable of pouring road drainage. Furthermore, in the construction of paving the road surface of the motorway in the tunnel, when paving the road surface of the motorway by the set form method or the slip method, the design load on the upper surface of the waterway block is increased as described above, It is possible to place the rail on which the set foam device travels and the traveling wheel of the slip foam device on the top wall of the water channel block. Moreover, the width of the upper surface wall of the water channel block having the rectangular water channel of the present invention is larger than that of the water channel block having the conventional circular water channel, but is wider, so that the set foam device and the slip foam device Thus, a margin is obtained so that the apparatus member integrally projecting from the side of the door does not contact the side wall on the road surface side of the supervisor passage.

  A conventional water channel block having a circular water channel is provided with a longitudinal slot in the upper wall and the upper wall is separated into left and right, so that the upper wall is weak against the load from the upper surface. In some cases, the slip foam device cannot be safely placed on the circular channel block. Moreover, even if the load is temporarily placed, the members protruding integrally from the side of the set foam device or slip foam device as described above may be blocked by the vertical wall of the observer passage and may not be placed. . In such a case, it is necessary to set a sufficient gap between the vertical wall of the supervisor passage and these set foam devices and slip foam devices, and these set foam devices are placed on the road surface to be paved. And slip-form equipment. In such a setting method of a set foam device or a slip foam device, an unpaved portion left unpaved is produced at the end portion of the road surface to be paved. However, since the above-mentioned channel block of the present invention has a rectangular channel, the width of the upper surface wall of the channel block is wide and the strength from the upper part is strong. A set foam device and a slip foam device can be placed on the surface, and as a result, the entire width of the automobile road surface can be paved all at once with the set foam device and the slip foam device.

  According to the present invention, the structure of the waterway for draining the road surface of the automobile road in the tunnel and the structure of the supervisor passage are the structures of the above-mentioned means, and in the invention of claim 1, the short surface of the waterway block having a rectangular waterway In the case where the same amount of water flows than the width of the short side of the water channel block having a conventional circular water channel, the width of the water channel block can be widened and the height of the water channel block having the rectangular water channel can be lowered accordingly. Therefore, by adopting this water channel block, the position of the structure part of the tunnel foundation can be increased upward, so that the tunnel excavation depth can be reduced, and if invert is provided at the lowest part of the tunnel foundation However, since the invert position can be increased, the substantial tunnel height can be reduced. As a result, the material cost and construction cost for constructing the tunnel can be greatly reduced. Furthermore, since the side wall of the water channel block is integrated as a vertical wall on the side of the supervisor channel, the construction of the supervisor channel can be performed simultaneously with the laying of the channel block, and various auxiliary facilities inside the supervisor channel, for example, The installation of road incidental facilities such as cables such as communication lines and power lines and water supply pipes can be carried out simultaneously with the installation of waterway blocks, so these constructions and installations proceed almost simultaneously with the progress of tunnel construction. So that tunnel construction can be carried out efficiently.

  Further, in the invention of claim 2, since the upper surface wall of the rectangular water channel block is provided with a plurality of road surface drainage inlets spaced apart and the upper surface wall is integrated, The top wall has sufficient strength to withstand the load from above. Therefore, the channel block having the rectangular channel of the present invention has an upper wall surface as compared with a conventional circular channel having a groove hole which is continuously opened in the longitudinal direction and is separated from the left and right, provided on the upper surface wall of the channel block of the circular channel. The strength of is extremely high. Therefore, the set form device and the slip form device for paving can be placed on the upper wall surface of the water channel block of the present invention, and the lateral width of the upper surface wall in the short direction is wide. The road surface can be paved while securing the position where it does not come into contact with the side of the roadway on the motorway side, and in a waterway block with a conventional circular waterway, a part of the mechanized device hits the vertical wall of the lifeguard path. Pavement by mechanization that could not be carried out because of contact can be realized efficiently. In addition, road surface drainage can be taken from the mouth formed on the top wall, but since the mouth is small and does not take in garbage that is larger than this small mouth, the frequency of cleaning with a high-pressure washing device is reduced, and it is quickly efficient. This can be carried out well, reducing the period of temporary road closure for pipe cleaning and further reducing the cost of cleaning the tunnel. Furthermore, as mentioned above, for example, cables such as communication lines and power lines, and water supply pipes such as communication lines and power lines can be laid along the paving machine in order while proceeding simultaneously with the paving machine. Therefore, the entire construction period in the tunnel can be shortened and the construction cost can be reduced, and the waterway block can sufficiently withstand the load from the upper surface as described above, so that the vehicle accidentally enters from the roadside belt. Even withstand enough. As described above, the present invention can achieve mechanization of construction, reduce the tunnel excavation depth, shorten the construction period, and reduce material costs and construction costs.

  As the best mode for carrying out the present invention, an embodiment of a tunnel structure of a motorway having a water channel block having a rectangular water channel and a supervisor channel will be described with reference to the drawings. FIG. 1 is a front view showing a short side surface of a water channel block having a rectangular water channel in the present invention. FIG. 2 is a plan view of the water channel block of FIG. FIG. 3 is a side view of the water channel block of FIG. FIG. 4 is a schematic cross-sectional view showing a tunnel structure having a tunnel, a supervisor passage, a waterway block, and an automobile road surface according to the present invention. FIG. 5 is a plan view of a water channel block having a concavo-convex surface comprising a ridge diagram. FIG. 6 is a diagram showing a tunnel structure having a rectangular water channel block of the present invention and a conventional circular water channel block.

  In FIG. 1, a water channel block 5 according to the present invention forms a rectangular water channel for draining a road surface of a tunnel 1 for an automobile road. As shown in FIG. 4, the automobile road tunnel 1 has a travel route of the automobile road 3 in the center of the tunnel lining 2. At the wall of one tunnel side wall 1b of the tunnel 1, there is a monitoring passage 4 which is raised to one level, and a road surface drainage having a road surface height is taken in between the monitoring passage 4 and the automobile road surface 3a. A water channel block 5 having a rectangular water channel 5a for draining is embedded. The water channel block 5 is a factory-produced precast water channel block, and has a rectangular water channel 5a that is horizontally long on the cut surface in the short direction. The water channel block 5 having the rectangular water channel 5a is a top surface wall in the short direction of the water channel block 7 having a circular water channel 7a in which the lateral width of the upper surface wall 5b in the short direction is the same as the rectangular water channel 5a. The road surface is formed by connecting a plurality of wide waterway blocks 5 to the side of the road surface 3a adjacent to the surveillance passage 4 provided on the side wall of the tunnel side wall 1b. A drainage channel is formed, and the side wall 5c on the side of the supervisor channel 4 of the channel block 5 is integrally extended upward from the upper surface wall 5b of the channel block 5, and the side wall 5c is vertically extended on the vehicle road surface side of the supervisor channel 4 The wall 4a is used. On the other hand, a water channel block 5 ′ having a rectangular water channel 5 a is similarly installed on the other tunnel side wall 1 b ′ of the tunnel 1 of FIG. 4. However, the side wall 5c 'on the side of the tunnel side wall 1b' of the water channel block 5 'is only slightly higher than the upper wall surface 5b, and a low-level passage 4' is formed between the side wall 5b 'and the tunnel side wall 1b'. is doing. Accordingly, no road-related facilities such as cables and water supply pipes are installed in the lower part of the low passage 4 '.

  In the above, as shown in FIG. 1, the side wall 5c of the water channel block 5 is the vertical wall 4a on the side of the vehicle movement road surface 3a of the monitoring person passage 4, but in this case, the monitoring person passage 4 is 940 mm from the vehicle movement road surface 3a. It is formed in an elevated position for safety. Therefore, the height of the side wall 5c of the water channel block 5 having the rectangular water channel 5a is also 940 mm upward from the upper surface wall 5b, and the thickness of the side wall 5c is 150 mm. Furthermore, the horizontal width of the upper surface wall 5b of the water channel block 5 in this case is 600 mm. The size of the rectangular water channel 5 a included in the water channel block 5 is 290 mm in height and 600 mm in width in the cross section in the short direction of the water channel block 5. Furthermore, the wall thicknesses of the upper surface wall 5b and the lower surface wall 5d of the water channel block 5 are both 80 mm. The length of the integral water channel block 5 in the longitudinal direction is, for example, 2000 mm.

  Further, as shown in FIG. 2, as a means of claim 2, the water channel block 5 having the rectangular water channel 5a therein is long in order to take in the road surface drainage penetrating from the upper surface of the upper surface wall 5b to the rectangular water channel 5a inside. A plurality of strip-shaped sheds 8 each having a horizontal side of 100 mm and a vertical side of 40 mm in width are arranged apart from each other in the longitudinal direction of the upper surface wall 5b, and the upper surface wall 5b is integrated into a single plate. ing. In this case, the strip-shaped shed 8 is set to have a distance of 230 mm, for example, with the adjacent shed 8 facing the lateral side of the channel block 5 in the short direction. Accordingly, eight sheds 8 are provided on the upper surface wall 5 b of one water channel block 5.

Further, in the construction of the tunnel 1 described above, the base 1a portion of the tunnel 1 is shown with an invert 6 formed to form the bottom of the tunnel 1 as shown in FIG. When constructing such an invert 6 at the bottom of the tunnel 1, in the case of the canal block 7 having the conventional circular canal 7a shown on the right side (B) of FIG. 6 , the upper surface wall 7b is flush with the road surface 3a. When the height is set, the invert 6 laid on the portion of the foundation 1a of the tunnel 1 and the corners of the side wall 7c and the lower surface wall 7d of the water channel block 7 overlap and interfere with each other, so that the water channel block 7 cannot be laid. . Therefore, as shown in (B) on the right side of FIG. 6, in order to prevent such an invert 6 and the corner of the lower side wall 7c of the water channel block 7 from overlapping, the portion of the foundation 1a of the tunnel 1 is deeply formed. It is necessary to deepen the position of the invert 6 by digging down and extending the tunnel side wall 1b downward. That is, in the case of the water channel block 7 of the conventional circular water channel 7a, the height of the side wall 7c of the water channel block 7 is the same as that of the water channel block 5 of the rectangular water channel 5a through which the road surface drainage of the same amount of water shown in FIG. It is larger than the height of the side wall 5c. Therefore, when the upper surface wall 5b of the water channel block 5 having the rectangular water channel 5a of the present invention is constructed as a road surface position, the excavation depth of the portion of the foundation 1a of the tunnel 1 is set to be less than the depth of the side wall 7c of the water channel block 7. Even if the invert 6 is laid shallow, the invert 6 does not overlap the lower corner of the water channel block 5 and does not interfere with the lower invert 6. Therefore, when constructing the canal block 5 having the rectangular canal 5a of the present invention so as to flow the same amount of water as the circular canal 7a, the canal block 5 is provided without interfering with the invert 6 below even if the dug depth is shallow. be able to. In this case, in the example shown in FIG. 6, between the tunnel structure of the present invention and the conventional tunnel structure, the position of the invert 6 at the center of the tunnel 1 is provided at a position shallower by about 24 cm in the present invention.

  The structure of the tunnel 1 shown in FIG. 4 will be further described. There is a supervisor passage 4 at the wall of the tunnel side wall 1b. The height of the supervisor passage 4 is 1000 mm from the upper wall surface 5b of the side wall 5c of the adjacent water channel block 5. Inside the supervisor passage 4, infrastructure facilities such as cables 4b such as various communication lines and power lines, or pipe facilities such as a water supply pipe 4c are laid. In addition, a handrail 4d is provided on the upper side of the side wall 5c of the water channel block 5 which is the vertical wall 4a of the monitoring person passage 4 for safety of the monitoring person passage 4.

  Further, unlike the water channel block 7 having the conventional circular water channel 7a, the upper surface wall 5b of the water channel block 5 having the rectangular water channel 5a in the present invention is as wide as at least 600 mm and is flush with the paved automobile road surface. Since it has an integral structure as described above, it can sufficiently withstand the load applied from above. On the other hand, the portion of the upper surface of the upper surface wall 5b of the water channel block 5 that is close to the automobile road surface 3 is in contact with the roadside belt for evacuation of the traveling vehicle, so that the car entering the roadside belt enters the upper wall 5 In this case, in order to notify that the vehicle has entered, the upper surface of the upper surface wall 5b near the road surface of the automobile road surface 3 is formed as an uneven surface composed of a plurality of spaced protrusions 9, as shown in FIG. It is also possible to make the driver sense that the vehicle has entered the water channel block 5 by generating vibrations and vibration noises when the vehicle is invaded by the vehicle.

  Next, a method for constructing the internal structure of the tunnel 1 for motorways in the present invention will be described. The water channel block 5 which is the vertical wall 4a of the supervisor passage 4 is used as an integral structure in which one side wall 5c is extended to a height of about 1000 mm above the upper surface wall 5b, and the supervisor passage 4 is formed at the wall of the tunnel side wall 1b. Shall be provided. In this case, first, the water channel block 5 is installed by disposing the side wall 5c extending upward from the tunnel side wall 1b with an appropriate space on the center side of the road on the tunnel side wall 1b side. Next, it is assumed that cables 4b such as communication wirings and power wirings and water pipes 4c of water supply facilities are laid under the passage of the supervisor passage 4. On the other hand, at the same time, the pavement 3b is formed on the lower foundation 1a of the motorway 3. For this purpose, for example, in order to lay concrete, one running wheel of a slip foam device that lays concrete while providing a movable formwork is formed on the upper surface wall 5b of the channel block 5 that is wide but can withstand a load. Place the other traveling wheel on the foundation 1a portion and place a movable formwork on the opposite side of the waterway block 5 while running, and use the waterway block 5 itself as a formwork. Then, concrete is poured between the water channel block 5 and the movable formwork and the concrete is laid. In this way, in the present invention, by using the water channel block 5 of the rectangular water channel 5a having the wide upper surface wall 5b, one traveling wheel of the slip form device is placed on the upper surface wall 5b of the water channel block 5 as described above. Even if placed on the side, the side wall 5c and the side portion of the slip-form device can travel and move forward without interference. Therefore, the concrete can be poured into the water channel block 5 without being left behind. Furthermore, in the present invention, since the side wall 5c is an integral structure and is used as the vertical wall 4a of the supervisor passage 4, the installation process for separately providing the vertical wall 4a of the supervisor passage 4 on the side of the water channel block and the time for the installation step are provided. do not need.

  As described above, when concrete is poured and solidified by the slip foam device, a rail for running one of the running wheels is laid on the water channel block 5 of the rectangular water channel 5a in order to put asphalt on the concrete, and the other Rails for traveling wheels are laid on a mold block provided on the center side of the road, and asphalt is paved while running a set form device for paving asphalt on these rails. Even in the case of this device, even if one running wheel of the set foam device is placed on the upper surface wall 5b of the water channel block 5, the side wall 5c and the side of the set foam device can travel and move forward without interference. . Therefore, the asphalt pavement can be done without leaving the block of the water channel block 5. In addition, concrete laying or asphalt pavement can be implemented by mechanization, and the construction of the surveillance passage 4 and the auxiliary equipment for the cables 4b and water pipes 4c can be implemented sequentially according to the road surface paving work. Each process can be carried out simultaneously, the construction cost can be reduced, and it has the advantage that it can be opened immediately if the test after installation is completed. Further, since the channel block 5 of the rectangular water channel 5a having a low height is formed, the excavation depth of the foundation 1a of the tunnel 1 is shallower than the excavation depth in the case of the water channel block 7 of the conventional circular water channel 7a having a high height. As a result, the construction time and cost of the entire tunnel process can be greatly reduced.
