Description

The present invention relates to an integrated column and an integrated column installation method.

A rainwater storage and infiltration system for eliminating utility poles has been proposed, in which conduit material for accommodating various power and communication cables is placed so that it penetrates a rainwater storage and infiltration tank buried under the sidewalk (Patent Document 1).

Japanese Patent Application Laid-Open No. 2019-35307

According to Patent Document 1, it is possible to effectively utilize the underground space beneath the sidewalk and eliminate utility poles. Eliminating utility poles is expected to reduce disasters and improve the urban landscape.

However, utility poles are not the only pole-like structures installed along roads. For example, pole-like structures are installed for a variety of purposes, such as streetlight and traffic light poles. These pole-like structures are installed individually by their respective managers, and therefore their exterior designs vary. Therefore, it is difficult to fully improve the urban landscape by eliminating utility poles using the system in Patent Document 1.

One aspect is to provide integrated pillars and other structures that contribute to improving the urban landscape.

The integrated pole comprises a first pole with one end buried underground, a second pole connected to the top of the first pole and on which electric lights and transformers are attached, and pipes for communications, electric lights, and electronic equipment installed inside the first and second poles, separated by a space for passing transformer cables.

On the one hand, it can provide integrated pillars that contribute to improving the urban landscape.

[First Embodiment]
In urban areas, the removal of utility poles is being promoted. By eliminating the electric wires that run between utility poles, it is expected that the landscape will be improved. Furthermore, it will also prevent accidents such as power outages and electric shocks caused by flying debris getting caught on electric wires during strong winds.

In areas where utility poles have been eliminated, power cables and communication cables are buried in utility trenches, which are often buried under roads. In areas where roads are wide, above-ground equipment enclosures containing power distribution equipment such as transformers and switches are installed beside the sidewalk. In areas where the sidewalks are narrow and it is difficult to install above-ground equipment, a so-called soft underground method is sometimes used, in which support poles with power distribution equipment installed on top are installed beside the road.

Electricity is stepped down by a transformer to, for example, 100 or 200 volts and then supplied to each electricity consumer via underground service lines. In the case of electricity for general households, a single transformer can supply electricity to a large number of consumers.

By the way, there are known phenomena where heavy rain occurs over an extended period of time in the same area due to linear rain bands, etc. When such heavy rain occurs in the upstream basin of a river, there is a risk that levees downstream will collapse, causing flooding damage. For example, if the levees of the Arakawa River were to collapse, it is predicted that a wide area in southern Saitama Prefecture and the 23 wards of Tokyo would suffer flooding damage of several meters.

Even with flooding of just 1 to 2 meters, above-ground equipment storage boxes installed beside the sidewalk will be submerged. Even in the case of soft underground installations, flooding of 4 to 5 meters is likely to damage power distribution equipment. Waterproofing measures are in place for underground facilities such as utility trenches in anticipation of flooding. However, if the distribution equipment connecting underground facilities to consumers is damaged, it will take time to restore power supply.

The following explanation focuses on the integrated pillar 30 (see Figure 1), which can reduce damage caused by large-scale flooding with inundation of up to 5 meters.

Figure 1 is an explanatory diagram illustrating an example of how an integrated pole 30 is used. Figure 1 shows an example of an integrated pole 30 installed near an intersection. The integrated pole 30 is cylindrical and has a box fixing portion 39 at its bottom. The box fixing portion 39 is fixed to a pole body mounting box installed in a utility cable trench. The box fixing portion 39 is buried underground.

From below, the integrated pole 30 is fitted with an electric light 78, a traffic light 77, a first device 71, a second device 72, a transformer 76, and a communication antenna 55. A lighting board storage opening cover 64 and an extension opening cover 65 (see Figure 2) are provided at the bottom of the integrated pole 30. A number of work step bolts 19 are attached to the top of the integrated pole 30.

The electric light 78 is connected to an electric light cable in the utility cable trench and receives power via the electric light cable. The electric light 78 is managed by a local government or a local residents' association. The manager of the electric light 78 can remove the opening cover 64 for storing the lighting board located at the bottom of the integrated pole 30 and perform maintenance on the lighting board located inside.

It is desirable to place a water inundation sensor 645 (see Figure 3) near the lighting board. The water inundation sensor 645 is configured to send a wireless or wired notification to a disaster prevention server, such as that of a local government or the Ministry of Land, Infrastructure, Transport and Tourism, if it detects water inundation. By automatically reporting water damage, an integrated pillar 30 can be realized that contributes to rapid disaster prevention measures.

Traffic lights 77 are connected to a traffic light cable in the utility cable tunnel and receive power and control signals via the traffic light cable. Traffic lights 77 may also be standalone types that, for example, switch between red and green at regular intervals. Traffic lights 77 are managed by the police.

Transformer 76 is connected to the power cable in the utility trench and the service line that sends power to consumers. Transformer 76 is an example of power distribution equipment that receives high-voltage power from the power cable and supplies the stepped-down power to consumers. Equipment essential for power distribution, such as switches (not shown), is also located near transformer 76. Transformer 76 is managed by the electric power company. In the following explanation, the high-voltage and low-voltage cables that pass through the inside of integrated pole 30 and connect to transformer 76 will be collectively referred to as transformer cables.

The communication antenna 55 is attached to an antenna support pole 555 installed on the opposite side of the integrated pole 30 from the transformer 76. The communication antenna 55 is connected to a communication cable in the utility trench. The communication antenna 55 is, for example, an antenna for a mobile phone, and is managed by a mobile phone company. Details of the communication antenna 55 will be described later.

The first device 71 and the second device 72 may be any device, such as a surveillance camera, a disaster prevention speaker, a sensor for a traffic control system, or a street display. The first device 71 and the second device 72 may also be a storage battery installed in preparation for a large-scale power outage. Optional devices, such as a third device and a fourth device (not shown), may also be attached to the integrated pole 30.

Multiple integrated poles 30 may each be fitted with different equipment. For example, as mentioned above, a traffic light 77 may be fitted to an integrated pole 30 installed near an intersection, but a traffic light 77 may not be fitted to an integrated pole 30 installed away from the intersection.

As explained above, the integrated pole 30 can be fitted with a variety of devices managed by different managers. Therefore, by using the integrated pole 30, the streetscape can be improved compared to when each equipment manager erects poles with different designs on the side of the road. Furthermore, compared to erecting multiple poles individually, manufacturing costs, installation costs, maintenance costs, and installation space can be reduced.

Figure 2 is a perspective view of the integrated pole 30. Figure 2 shows the integrated pole 30 before various devices such as electric lights 78 are installed. The installer of the integrated pole 30 installs the integrated pole 30 in the state shown in Figure 2 at the specified location. Then, each manager installs the devices such as electric lights 78.

The integrated column 30 is composed of a first column 10 and a second column 20. The first column 10 has a box fixing portion 39, and its lower portion is buried underground. The second column 20 is fixed to the upper portion of the first column 10.

Figure 3 is a view taken along the line III in Figure 2. The approximate dimensions of the integrated column 30 will be explained using Figure 3. Note that the dimensions shown below are all examples. The dimensions of the integrated column 30 are not limited to the dimensions below.

It is desirable that the first pole be 5 meters or longer. In this embodiment, the length L1 of the first pole 10 is 5,190 millimeters. The length L2 of the second pole 20 is 4,900 millimeters. G. L (Ground Level) indicates the height above ground. The depth to which the first pole 10 is buried in the ground depends on the depth of the pole body mounting box installed in the utility cable trench, but is approximately 650 to 800 millimeters.

The total length of the integrated pole 30, excluding the antenna support pole 555, is approximately 10 meters, and its height from the ground is just over 9 meters. The first outer pipe 11 (see Figure 4) and second outer pipe 21 (see Figure 6), which are the exterior components of the integrated pole 30, are steel pipes with a diameter of 267.4 mm. By using steel pipes with dimensions supplied as standard by steel pipe manufacturers, the manufacturing cost of the integrated pole 30 can be reduced.

The lighting board storage opening lid 64 and the extension opening lid 65 are located at a height of 1.6 meters or less above ground level. This allows local government officials and other personnel to open and close the lighting board storage opening lid 64 and the extension opening lid 65 without using a stepladder or other device.

Figure 4 is a perspective cross-sectional view taken along line IV-IV in Figure 2. A roughly square base plate 38 is welded to the lower end of the integrated column 30. A roughly L-shaped rib is welded between the base plate 38 and the side of the integrated column 30. A box-shaped box fixing portion 39 is fixed to the upper side of the base plate 38 by welding and bolting. The inner surface of the box fixing portion 39 is connected to the inner surface of the first outer pipe 11, allowing cables to be passed through.

A communication pipe fixture 47, which is roughly D-shaped, is welded to the inner surface of the first outer pipe 11. The communication pipe fixture 47 has three holes. The lower first electronic device pipe 411, the lower second electronic device pipe 421, and the lower communication pipe 451 are inserted through the holes, respectively.

Figure 5 is a perspective cross-sectional view taken along line V-V in Figure 2. A lamp tube fixture 48, which is roughly D-shaped, is welded to the inner surface of the first outer tube 11. The lamp tube fixture 48 is positioned several centimeters above the upper end of the extension opening cover 65. Two holes are provided in the lamp tube fixture 48. A lower lamp tube 461 and a lower third electronic device tube 431 are inserted into the respective holes.

Figure 6 is a perspective cross-sectional view taken along line VI-VI in Figure 2. A lamp tube fixture 48 having a generally D-shaped plate shape is welded to the inner surface of the second outer tube 21. The lamp tube fixture 48 has two holes. An upper lamp tube 462 and an upper third electronic device tube 432 are inserted into the respective holes. The upper third electronic device tube 432 and the lower third electronic device tube 431, and the upper lamp tube 462 and the lower lamp tube 461 are respectively arranged in a generally straight line.

A communication pipe fixture 47, which is approximately D-shaped, is welded to the inner surface of the second outer pipe 21. The communication pipe fixture 47 has three holes. The upper first electronic device pipe 412, the upper second electronic device pipe 422, and the upper communication pipe 452 are inserted through the holes, respectively. The upper first electronic device pipe 412 and the lower first electronic device pipe 411, the upper second electronic device pipe 422 and the lower second electronic device pipe 421, and the upper communication pipe 452 and the lower communication pipe 451 are each arranged in a substantially straight line.

In the following explanation, the lower lighting tube 461 and the upper lighting tube 462 may be collectively referred to as lighting tube 46 (see Figure 7). Similarly, the lower communication tube 451 and the upper communication tube 452 may be referred to as communication tube 45 (see Figure 8), and the lower first electronic device tube 411, the upper first electronic device tube 412, the lower second electronic device tube 421, the upper second electronic device tube 422, the lower third electronic device tube 431, and the upper third electronic device tube 432 may be referred to as electronic device tubes 41 (see Figure 7).

The center of the integrated pole 30 is the space where the transformer cable is placed when a transformer 76 is attached to the integrated pole 30. As shown in Figures 4 to 6, the communication pipe 45 and the lighting pipe 46 are arranged opposite each other, with the space where the transformer cable is placed in between.

Figure 7 is an enlarged cross-sectional view taken along line VII-VII in Figure 6. As shown in Figures 6 and 7, a brim-shaped second flange 23 is welded to the lower end of the second outer pipe 21. Similarly, a brim-shaped first flange 13 is welded to the upper end of the first outer pipe 11. The first flange 13 and the second flange 23 have multiple bolt holes. The first flange 13 and the second flange 23 are butt-jointed and fastened together with bolts and nuts.

The lower lamp tube 461 and the lower third electronic device tube 431, which are arranged inside the first outer tube 11, extend from the upper side of the extension opening cover 65 as shown in FIG. 5 to near the upper end of the first outer tube 11 as shown in FIG. 7. The lengths of both tubes are approximately the same.

The upper lamp tube 462, located inside the second outer tube 21, has a length from near the bottom end of the second outer tube 21 to the lower side of the lamp outlet 56 to which the lamp 78 is attached in Figure 1. The upper third electronic device tube 432 has a length from near the bottom end of the second outer tube 21 to the upper side of the first electronic device outlet 511 to which the traffic light 77 is attached in Figure 1.

Lighting tube fixtures 48 are welded to the inner surfaces of the first outer tube 11 and second outer tube 21 near both ends of the lighting tube 46, the lower third electronic device tube 431, and the upper third electronic device tube 432. A stopper 49 with a larger diameter than the hole in the lighting tube fixture 48 is attached to the end of each tube.

Figure 8 is an enlarged cross-sectional view taken along line VIII-VIII in Figure 6. The lower communication tube 451, the lower first electronic device tube 411, and the upper first electronic device tube 412, which are arranged inside the first outer tube 11, have lengths that extend from the upper side of the box fixing portion 39 as shown in Figure 4 to near the upper end of the first outer tube 11 as shown in Figure 8. The three tubes are approximately the same length.

The lower first electronic device tube 411 and the upper first electronic device tube 412 have a length that extends from near the bottom end of the second outer tube 21 to the upper side of the first electronic device outlet 511, where the traffic light 77 is attached in Figure 1. The two tubes are approximately the same length.

Figure 9 is a perspective cross-sectional view taken along line IX-IX in Figure 2. A lid is welded to the upper end face of the second outer tube 21. The upper communication tube 452 has a length that extends from near the bottom end of the second outer tube 21 to below the part where the antenna support pole 555 is attached, as shown in Figure 8.

Communication tube fixtures 47 are welded to the inner surface of the first outer tube 11 and the second outer tube 21 near both ends of the communication tube 45, the lower first electronic device tube 411, the upper first electronic device tube 412, the lower second electronic device tube 421, and the upper second electronic device tube 422. A stopper 49 with a larger diameter than the hole provided in the lamp tube fixture 48 is attached to the end of each tube.

The procedure for fixing each pipe inside the first outer pipe 11 and second outer pipe 21 will be explained using the upper communication pipe 452 as an example. A stopper 49 is attached to one end of the upper communication pipe 452. The upper communication pipe 452 is inserted into the hole in the communication pipe fixture 47 from the side without the stopper 49. Once it passes through the holes in each of the three communication pipe fixtures 47, the stopper 49 abuts against the electric light pipe fixture 48. A stopper 49 is attached to the other end of the upper communication pipe 452.

The distance between the stoppers 49 on both ends of the upper communication pipe 452 is slightly longer than the distance between the two communication pipe fixing devices 47 on both ends. Therefore, the upper communication pipe 452 can move longitudinally inside the second outer pipe 21.

In this way, the upper communication pipe 452 is attached inside the second outer pipe 21. Because no strong fastening, such as welding or screw fastening, is used between the second outer pipe 21 and the upper communication pipe 452, even if thermal expansion occurs in the second outer pipe 21 due to, for example, solar radiation, no thermal stress is applied to the upper communication pipe 452 inside. The same applies to the other pipes placed inside the first outer pipe 11 and second outer pipe 21.

Figure 10 is an enlarged view of the X portion in Figure 2. Figure 11 is an enlarged perspective view of the integrated column 30 with the opening cover 61 removed. Figures 10 and 11 show the same location. Figure 12 is a perspective cross-sectional view taken along line XII-XII in Figure 11.

In Figure 1, the first electronic device outlet 511, to which the traffic light 77 is attached, and the second electronic device outlet 512, to which the first device 71 is also attached, are located at the same height and 180 degrees apart from each other with respect to the central axis of the second outer tube 21.

The third electronic device outlet 513, to which the second device 72 is attached in FIG. 1, is arranged in the same direction as the second electronic device outlet 512 with respect to the central axis of the second outer tube 21. The fourth electronic device outlet 514, to which no device is attached in FIG. 1, is arranged in the same direction as the first electronic device outlet 511 with respect to the central axis of the second outer tube 21 and at the same height as the third electronic device outlet 513. In the following description, the first electronic device outlet 511, second electronic device outlet 512, third electronic device outlet 513, and fourth electronic device outlet 514 may be collectively referred to as electronic device outlets 51.

Three access openings 54 are located at an intermediate height between the first electronic device drawer 511 and the third electronic device drawer 513. The access openings 54 are spaced apart 120 degrees from each other and evenly spaced in the angular direction relative to the central axis of the second outer tube 21. As shown in Figure 10, an opening cover 61 is attached to each access opening 54.

The access opening 54 is constructed by welding a box-shaped opening frame 62 to a square hole in the side of the second outer pipe 21. The bottom of the opening frame 62 has a rectangular hole and four bolt holes. A nut is fixed to the back of each bolt hole. Instead of using nuts, screw holes may be formed in the bottom of the opening frame 62 by burring or other means. The opening cover 61 is fixed to the bottom of the opening frame 62 using four bolts.

As shown in FIG. 11, when no opening cover 61 or the like is attached, the access opening 54 and the electronic device drawer outlet 51 have the same structure. Therefore, an access opening 61 is attached to an unused electronic device drawer outlet 51, such as the fourth electronic device drawer outlet 514 in FIG. 1, in the same way as the access opening 54.

The traffic light 77, first device 71, and second device 72 can be easily attached to the integrated pole 30 by configuring them with four bolt holes arranged in the same manner as the opening cover 61. When fixing heavy or large equipment, it is desirable to attach them to the integrated pole 30 using multiple opening frames 62, such as the antenna support pole 555 shown in Figure 9. Using a common opening frame 62 for multiple uses reduces the manufacturing cost of the integrated pole 30. The opening frame 62 to which the antenna support pole 555 is attached is an example of a communications antenna mounting fixture.

The following describes an overview of how to use the access opening 54, using the installation of a traffic light 77 as an example. As mentioned above, the access opening 54 is normally fitted with an access cover 61. The worker removes three access covers 61. In addition to the upper end of the upper third electronic device tube 432 shown in Figures 11 and 12, the upper ends of the lower first electronic device tube 411 and upper first electronic device tube 412 are also located near the access opening 54, although they are hidden by the front part of the second outer tube 21 in Figure 12 and cannot be seen.

The worker drops the end of the traffic light cable extending from the traffic light 77 into, for example, the interior of the upper third electronic equipment pipe 432. Because three work openings 54 are open, the worker can use both hands to work inside the integrated pole 30. Therefore, even if, for example, a transformer cable is hanging over the top end of the upper third electronic equipment pipe 432, the worker can install the traffic light 77 without any problems.

After completing installation of the traffic light 77, workers attach an opening cover 61 to the work opening 54. Because the work opening 54 remains closed except during work, birds can be prevented from building nests inside the integrated pillar 30.

The transformer 76 is fixed to the integrated column 30 using two transformer mounting fixtures 67 shown in Figure 3. The transformer mounting fixtures 67 are, for example, hanger seats. The two transformer mounting fixtures 67 are arranged side by side in the height direction of the integrated column 30.

Figure 13 is a view as seen from the arrow XIII in Figure 1. Using Figures 1 and 13, we will explain the positional relationship between the transformer 76 and the communication antenna 55 when both are attached to the integrated pole 30.

The communication antenna 55 is, for example, an antenna for 5G. The communication antenna 55 is composed of a first antenna 551, a second antenna 552, and a third antenna 553, which are evenly spaced apart in the angular direction at 120 degrees from each other on the antenna support pole 555. Of these, the first antenna 551 is positioned facing the integrated pole 30 and the transformer 76. The communication cable extending from the communication antenna 55 is inserted into the upper communication pipe 452 via the communication opening 556 shown in Figure 9.

5G uses a high frequency, making it susceptible to obstacles. Therefore, if the first antenna 551 and the transformer 76 were placed at the same height, the radio waves emitted from the first antenna 551 would be subject to radio interference from the transformer 76.

However, as shown in FIG. 1, the first antenna 551 is positioned higher than the upper end of the second outer tube 21 and the upper end of the transformer 76. Therefore, an integrated pole 30 can be provided that prevents radio wave interference caused by the transformer 76.

Figure 14 is an explanatory diagram illustrating the first column 10 and the second column 20. Figure 14 will be used to provide an overview of how to manufacture and install the integrated column 30.

First, the first column 10 and second column 20 are manufactured in a factory. The second column 20 will be used as an example. Square holes for attaching the opening frame 62 and other components, and round holes for attaching the step bolts 19 are made in the side of the second outer pipe 21, a steel pipe cut to specified dimensions. The pre-fabricated opening frame 62 is welded to the square holes. A communication pipe fixture 47 and an electric lighting pipe fixture 48 are welded to the inner surface of the second outer pipe 21. A second flange 23 is welded to one end of the second outer pipe 21.

Electronic device tubes 41, communication tubes 45, and electric lighting tubes 46, each with a stopper 49 attached to one end, are inserted into the designated holes provided in the communication tube fixture 47 and electric lighting tube fixture 48. Then, a stopper 49 is attached to the other end of these tubes.

A cover is welded to the other end of the second outer pipe 21. A transformer mounting fixture 67 is welded to the side of the second outer pipe 21. A step bolt 19 is attached to the round hole by welding or screwing. An opening cover 61 is fixed to the working opening 54 and the opening frame 62 that is not scheduled to be used immediately. An antenna support pillar 555 is fixed to the upper opening frame 62. This completes the second pillar 20. The first pillar 10 is also made using roughly the same procedure.

The first column 10 and the second column 20 are transported to the installation site of the integrated column 30. The box fixing portion 39 of the first column 10 is fixed to a column body mounting box installed in the electric cable common trench. Furthermore, anchor bolts are inserted into holes in the base plate 38, firmly fixing the first column 10.

The second pillar 20 is placed on top of the first pillar 10. The first flange 13 and the second flange 23 are fastened together, connecting the second pillar 20 to the top of the first pillar 10. This completes the installation of the integrated pillar 30. Note that parts that are fixed with screws, such as the opening cover 61 and antenna support pillar 555, may be installed at the installation site instead of at the factory.

Since no welding work is required at the installation site, the integrated pole 30 can be installed in a relatively short time. After installing the integrated pole 30 using the standardized first pole 10 and second pole 20, various businesses can install equipment such as lights 78, traffic lights 77, first equipment 71, and second equipment 72 as needed, providing an integrated pole 30 that can be used according to local conditions.

Because the first pillar 10 and second pillar 20 are manufactured separately, there is no need to use large trucks for transporting long items to transport the equipment required to install the integrated pillar 30. This reduces the installation cost of the integrated pillar 30.

The integrated pillar 30 may be manufactured in three or more sections and then connected at the installation site. For example, it may be divided into three sections while maintaining a total length of approximately 10 meters. For example, if another pillar of approximately the same length as the second pillar 20 mentioned above is added, an integrated pillar 30 with a total length of approximately 15 meters can be installed.

The first column 10 and the second column 20 may be manufactured in a customized state depending on the intended use of the integrated column 30. For example, the mounting position of the opening frame 62, the number and length of the tubes placed inside, etc. may be changed depending on the intended use, and the columns may be manufactured in a factory.

Figure 15 shows an example of how the extension opening 651 is used. Figure 15 shows the state with the extension opening cover 65 removed. The cable visible on the right side of Figure 15 is a cable extending from the top of the extension opening cover 65 toward the electric cable joint trench. Two power connectors 17 are housed inside the extension opening 651.

The power supply connector 17 is, for example, a 100-volt plug and a 200-volt plug. For example, if a widespread power outage occurs and power is no longer supplied from the power cable in the common power supply channel, a power supply vehicle or electric vehicle can be connected to the power supply connector 17 to supply power to equipment necessary for disaster recovery, such as traffic lights 77 and communication antennas 55. Note that the uses of the extension opening 651 are not limited to those shown in Figure 15.

The technical features (constituent elements) described in each embodiment can be combined with each other, and by combining them, new technical features can be formed.
The embodiments disclosed herein are illustrative in all respects and should not be considered as limiting. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
