JP 2019-35307 Publication

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

However, utility poles are not the only pillar-like structures installed on the sides of roads. For example, columnar structures for various purposes, such as poles for streetlights and traffic lights, are installed. These columnar structures are installed individually by each administrator, so their external designs vary. Therefore, it is difficult to sufficiently improve the urban landscape by eliminating utility poles using the system of Patent Document 1.

One aspect is the purpose of providing integrated pillars that contribute to improving the urban landscape.

The integrated pillar includes a first pillar whose one end is buried underground, a second pillar connected to the top of the first pillar to which electric lights and a transformer are attached, and the first pillar and the second pillar. Inside the two pillars, a communication tube, a light tube, and an electronic device tube are provided with a space for passing a transformer cable separated from each other.

One aspect is that it can provide integrated pillars that contribute to improving the urban landscape.

[Embodiment 1]
In urban areas, the elimination of utility poles is being promoted. The scenery is expected to improve by eliminating the electric wires strung between utility poles. Furthermore, accidents such as power outages and electric shocks caused by flying objects getting caught in electric wires during strong winds can be prevented.

In areas where utility poles have been eliminated, power cables, communication cables, etc. are buried, for example, in utility cable ditches. Common power cable ditches are often buried under roads. In places where roads are wide, ground equipment storage boxes containing power distribution equipment such as transformers and switches are installed beside the sidewalk. In places where it is difficult to install above-ground equipment due to narrow sidewalks, a so-called soft underground method may be adopted, in which support poles with power distribution equipment installed on top are installed on the side of the road.

Power that is stepped down to, for example, 100 volts or 200 volts by a transformer is supplied to each power consumer via a service line buried underground. In the case of electricity for general households, a single transformer can supply electricity to many consumers.

By the way, it is known that heavy rain occurs in the same area for a long time due to linear precipitation bands. If such a torrential rain event occurs in the upper reaches of a river, there is a risk that the levees in the lower reaches will burst, causing flooding. For example, if the Arakawa River were to burst its embankments, it is predicted that large areas in southern Saitama Prefecture and Tokyo's 23 wards would be flooded several meters deep.

Even if the water level is 1 to 2 meters deep, ground equipment storage boxes installed next to sidewalks will be submerged. Even in the case of a soft underground system, there is a high possibility that power distribution equipment will be damaged by flooding of about 4 to 5 meters. Waterproofing measures have been implemented for underground facilities such as electric cables and common ditches in anticipation of flooding. However, if power distribution equipment or the like that connects underground facilities and consumers is damaged, it takes time to restore power supply.

In the following explanation, an integrated column 30 (see FIG. 1) that can reduce damage caused by large-scale flood damage caused by 5 meters of flooding will be described.

FIG. 1 is an explanatory diagram illustrating an example of how the integrated pillar 30 is used. FIG. 1 shows an example of an integrated pillar 30 installed near an intersection. The integrated pillar 30 has a cylindrical shape and includes a square fixing part 39 at the bottom. The cell fixing part 39 is fixed to a column attachment cell provided in the electric wire common groove. The cell fixing part 39 is buried underground.

An electric light 78, a traffic light 77, a first device 71, a second device 72, a transformer 76, and a communication antenna 55 are attached to the integrated pillar 30 from below. At the bottom of the integrated column 30, an opening lid 64 for storing lighting boards and an opening lid 65 for extension (see FIG. 2) are provided. A plurality of step bolts 19 for working are attached to the upper part of the integrated column 30.

The electric light 78 is connected to the electric light cable in the electric wire common ditch, and receives power supply via the electric light cable. The electric lights 78 are managed by local governments or local residents' associations. The administrator of the electric light 78 can remove the lighting board storage opening cover 64 placed at the bottom of the integrated column 30 and perform maintenance on the lighting boards placed inside.

It is desirable that a water immersion sensor 645 (see FIG. 3) be placed near the lighting board. The flood sensor 645 is configured to send a notification wirelessly or wired to a disaster countermeasure server of a local government or the Ministry of Land, Infrastructure, Transport and Tourism, for example, when a flood is detected. By automatically reporting flood damage, it is possible to realize integrated pillar 30 that contributes to prompt disaster countermeasures.

The traffic light 77 is connected to a traffic light cable in the electric utility line, and receives power and control signals via the traffic light cable. The traffic light 77 may be of a stand-alone type, such as one that switches between red and blue at regular intervals, for example. Traffic light 77 is managed by the police.

The transformer 76 is connected to a power cable in the utility line and a drop-in line that transmits power to customers. The transformer 76 is an example of a power distribution device that receives high-voltage power from a power cable and supplies step-down power to consumers. Equipment essential for power distribution, such as a switch (not shown), is also arranged near the transformer 76. The transformer 76 is managed by the electric power company. In the following description, the high-voltage side cable and the low-voltage side cable that pass through the inside of the integrated column 30 and are connected to the transformer 76 are collectively referred to as a transformer cable.

The communication antenna 55 is attached to an antenna support column 555 installed on the opposite side of the transformer 76 with the integrated column 30 in between. The communication antenna 55 is connected to a communication cable in the electric wire common 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 are arbitrary devices 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 be storage batteries placed in preparation for a large-scale power outage. Any equipment such as a third equipment, a fourth equipment, etc., which are not shown, may be attached to the integrated pillar 30.

Different devices may be attached to each of the plurality of integrated pillars 30. For example, as described above, the traffic light 77 is attached to the integrated pole 30 installed near the intersection, but the traffic light 77 is not attached to the integrated pole 30 installed away from the intersection.

As explained above, various devices managed by various managers are attached to the integrated pillar 30. Therefore, by using the integrated pillar 30, the scenery of the city can be improved compared to a case where the managers of each device erect pillars with different designs on the side of the road. Furthermore, manufacturing costs, installation costs, maintenance costs, and installation space can be reduced compared to the case where a plurality of pillars are individually erected.

FIG. 2 is a perspective view of the integrated column 30. FIG. 2 shows the integrated pole 30 before various equipment such as a light 78 is attached. A company installing the integrated pillar 30 installs the integrated pillar 30 in the state shown in FIG. 2 at a predetermined location. After that, each manager installs equipment such as electric lights 78.

The integrated pillar 30 is composed of a first pillar 10 and a second pillar 20. The first pillar 10 includes a square fixing part 39, and a lower part thereof is buried underground. The second pillar 20 is fixed to the upper part of the first pillar 10.

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

It is desirable that the first pillar is 5 meters or more. In this embodiment, the length L1 of the first pillar 10 is 5190 mm. The length L2 of the second pillar 20 is 4900 mm. G. L (Ground Level) indicates the height of the ground. The depth of the part where the first pillar 10 is buried in the ground is approximately 650 mm to 800 mm, although it depends on the depth of the pillar attachment box provided in the electric cable common trench.

Therefore, the total length of the integrated column 30 excluding the antenna support column 555 is approximately 10 meters, and the height from the ground is a little over 9 meters. The first outer tube 11 (see FIG. 4) and the second outer tube 21 (see FIG. 6), which are exterior members of the integrated column 30, are steel tubes with a diameter of 267.4 mm. The manufacturing cost of the integrated column 30 can be reduced by using a steel pipe with dimensions supplied as a standard product by a steel pipe manufacturer.

The lighting board storage opening lid 64 and the extension opening lid 65 are arranged at a location where the height above the ground is 1.6 meters or less. Therefore, a person in charge of a local government or the like can open and close the lighting board storage opening cover 64 and the extension opening cover 65 without using a stepladder or the like.

FIG. 4 is a perspective sectional view taken along line IV-IV in FIG. 2. A substantially square base plate 38 is welded to the lower end of the integrated column 30. A substantially L-shaped plate-shaped rib is welded between the base plate 38 and the side surface of the integrated column 30. A box-shaped square fixing part 39 is fixed to the upper side of the base plate 38 by welding and bolting.

The upper third electronic device tube 432 and the lower third electronic device tube 431, and the upper electric light tube 462 and the lower electric light tube 461 are each arranged substantially in a straight line.

A communication tube fixture 47 having a substantially D-shaped plate shape is welded to the inner surface of the second outer tube 21 . The communication tube fixture 47 is provided with three holes. An upper first electronic device tube 412, an upper second electronic device tube 422, and an upper communication tube 452 are inserted into the respective holes. The upper first electronic device tube 412 and the lower first electronic device tube 411, the upper second electronic device tube 422 and the lower second electronic device tube 421, and the upper communication tube 452 and the lower communication tube 451 are , are arranged substantially in a straight line.

In the following description, the lower electric light tube 461 and the upper electric light tube 462 may be collectively referred to as the electric light tube 46 (see FIG. 7). Similarly, the lower communication tube 451 and the upper communication tube 452 are described as the communication tube 45 (see FIG. 8), and the lower first electronic device tube 411, the upper first electronic device tube 412, and the lower second electronic device tube 45 are referred to as communication tubes 45 (see FIG. 8). The 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 the electronic device tube 41 (see FIG. 7).

The center of the integrated column 30 is a space in which a transformer cable is placed when the transformer 76 is attached to the integrated column 30. As shown in FIGS. 4 to 6, the communication pipe 45 and the electric light pipe 46 are arranged opposite to each other with a space in which the transformer cable is arranged.

FIG. 7 is an enlarged sectional view taken along line VII-VII in FIG. 6. As shown in FIGS. 6 and 7, a brim-shaped second flange 23 is welded to the lower end of the second outer tube 21. As shown in FIGS. Similarly, a brim-shaped first flange 13 is welded to the upper end of the first outer tube 11. A plurality of bolt holes are provided in the first flange 13 and the second flange 23. The first flange 13 and the second flange 23 are butted against each other and fastened together with bolts and nuts.

The lower electric light tube 461 and the lower third electronic device tube 431 disposed inside the first outer tube 11 are inserted from the upper side of the extension opening cover 65 as shown in FIG. 5, and as shown in FIG. This is the length up to the vicinity of the upper end of the first outer tube 11. Both lengths are approximately the same.

The upper electric light tube 462 disposed inside the second outer tube 21 has a length from near the lower end of the second outer tube 21 to the lower side of the electric light outlet 56 to which the electric light 78 is attached in FIG. . The upper third electronic device tube 432 has a length from near the lower 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 FIG.

An electric light tube fixture 48 is welded to the inner surfaces of the first outer tube 11 and the second outer tube 21 near both ends of the electric light tube 46, the lower third electronic device tube 431, and the upper third electronic device tube 432, respectively. has been done. A stopper 49 having a diameter larger than the hole provided in the electric light tube fixture 48 is attached to the end of each tube.

FIG. 8 is an enlarged sectional view taken along line VIII-VIII in FIG. 6. As shown in FIG. This is the length from the top to the vicinity of the upper end of the first outer tube 11 as shown in FIG. The lengths of the three tubes are approximately the same.

The lower first electronic device tube 411 and the upper first electronic device tube 412 have a length from near the lower 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 FIG. It is. The lengths of the two tubes are approximately the same.

9 is a perspective sectional view taken along line IX-IX in FIG. 2. FIG. A lid is welded to the upper end surface of the second outer tube 21. As shown in FIG. 8, the upper communication tube 452 has a length from near the lower end of the second outer tube 21 to below the portion where the antenna support column 555 is attached.

Near both ends of each 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, the first outer tube A communication tube fixture 47 is welded to the inner surfaces of the communication tube 11 and the second outer tube 21. A stopper 49 having a diameter larger than the hole provided in the electric light tube fixture 48 is attached to the end of each tube.

The procedure for fixing each tube inside the first outer tube 11 and the second outer tube 21 will be explained using the upper communication tube 452 as an example. A stopper 49 is attached to one end of the upper communication pipe 452. The upper communication tube 452 is inserted into the hole of the communication tube fixture 47 from the side where the stopper 49 is not attached. After passing through the holes provided in the three communication tube fixtures 47, the stopper 49 abuts against the electric light tube fixture 48. A stopper 49 is attached to the other end of the upper communication pipe 452.

The distance between the stoppers 49 at both ends of the upper communication pipe 452 is slightly longer than the distance between the two communication pipe fixtures 47 at both ends. Therefore, the upper communication tube 452 is movable in the longitudinal direction inside the second outer tube 21.

As described above, the upper communication tube 452 is attached inside the second outer tube 21. Since the second outer tube 21 and the upper communication tube 452 are not firmly fixed by welding or screw fixing, the second outer tube 21 may undergo thermal expansion due to solar radiation, for example. However, no thermal stress is applied to the internal upper communication pipe 452. The same applies to other tubes arranged inside the first outer tube 11 and the second outer tube 21.

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

In FIG. 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 based on the central axis of the second outer tube 21. They are placed at the same height and 180 degrees apart from each other.

A 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 . 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, there is a 4 electronic device outlet 514 are arranged. In the following description, the first electronic device outlet 511, the second electronic device outlet 512, the third electronic device outlet 513, and the fourth electronic device outlet 514 will be collectively referred to as the electronic device outlet 51. May be stated.

Three work openings 54 are arranged at an intermediate height between the first electronic device outlet 511 and the third electronic device outlet 513. The working openings 54 are spaced apart from each other by 120 degrees and are equally arranged in the angular direction with respect to the central axis of the second outer tube 21 as a reference. As shown in FIG. 10, an opening cover 61 is attached to each working opening 54. As shown in FIG.

The working opening 54 has a box-shaped opening frame 62 welded to a square hole provided on the side surface of the second outer tube 21 . A rectangular hole and four bolt holes are provided on the bottom surface of the opening frame 62. A nut is fixed to the back side of each bolt hole. Instead of using nuts, screw holes may be provided on the bottom surface of the opening frame 62 by burring or the like. The opening lid 61 is fixed to the bottom surface of the opening frame 62 using four bolts.

As shown in FIG. 11, when the opening cover 61 and the like are not attached, the working opening 54 and the electronic device outlet 51 have the same structure. Therefore, an opening cover 61 is attached to the electronic device outlet 51 that is not used, such as the fourth electronic device outlet 514 in FIG. 1, in the same way as the working opening 54.

The traffic light 77, the first device 71, the second device 72, etc. can be easily attached to the integrated column 30 by configuring them to have four bolt holes arranged similarly to the opening cover 61. When fixing a heavy device or a large device, it is desirable to attach it to the integrated column 30 using a plurality of opening frames 62, such as the antenna support column 555 shown in FIG. 9, for example. By using the common opening frame 62 for multiple uses, the manufacturing cost of the integrated column 30 can be reduced. The opening frame 62 to which the antenna support column 555 is attached is an example of a communication antenna mount.

An overview of how to use the work opening 54 will be explained by taking as an example a case where a traffic light 77 is to be installed. As mentioned above, the opening cover 61 is normally attached to the working opening 54. The person in charge of the work removes the three opening lids 61. In the vicinity of the working opening 54, in addition to the upper end of the upper third electronic device tube 432 shown in FIGS. Although not visible, the upper ends of the lower first electronic device tube 411 and the upper first electronic device tube 412 also exist.

The person in charge of the work drops the tip of the signal cable extending from the signal 77 into, for example, the upper third electronic equipment pipe 432 . Since the three working openings 54 are open, the worker can work inside the integrated column 30 using both hands. Therefore, even if, for example, the transformer cable covers the vicinity of the upper end of the upper third electronic device pipe 432, the person in charge of the work can install the traffic signal 77 without any problem.

After completing the installation of the traffic light 77, the operator attaches the opening cover 61 to the working opening 54. Since the working opening 54 is closed except during working, it is possible to prevent birds from nesting inside the integrated column 30.

Transformer 76 is secured to consolidation column 30 using two transformer mounts 67 shown in FIG. The transformer fixture 67 is, for example, a hanger seat. The two transformer fixtures 67 are arranged side by side in the height direction of the integrated column 30.

FIG. 13 is a view taken along arrow XIII in FIG. The positional relationship between the transformer 76 and the communication antenna 55 when both are attached to the integrated pillar 30 will be described using FIGS. 1 and 13.

The communication antenna 55 is, for example, a 5G antenna. The communication antenna 55 is composed of a first antenna 551, a second antenna 552, and a third antenna 553, which are equally arranged in the angular direction and 120 degrees apart from each other with respect to the antenna support column 555. Of these, the first antenna 551 is arranged toward the integrated pillar 30 and transformer 76 side. A communication cable extending from the communication antenna 55 is inserted into the upper communication pipe 452 via a communication opening 556 shown in FIG.

Since 5G has a high frequency, it is easily affected by obstacles. Therefore, if the first antenna 551 and the transformer 76 are placed at the same height, the radio waves radiated from the first antenna 551 will be interfered with by the transformer 76.

However, as shown in FIG. 1, the first antenna 551 is arranged at a higher position than the upper end of the second outer tube 21 and the upper end of the transformer 76. Therefore, it is possible to provide the integrated pillar 30 that prevents radio wave interference caused by the transformer 76.

FIG. 14 is an explanatory diagram illustrating the first pillar 10 and the second pillar 20. FIG. 14 will be used to outline a method for manufacturing and installing the integrated column 30.

First, the first pillar 10 and the second pillar 20 are manufactured in a factory. The second pillar 20 will be explained as an example. A square hole for attaching the opening frame 62 and the like and a round hole for attaching the step bolt 19 are made on the side surface of the second outer tube 21, which is a steel tube cut to a predetermined size. An opening frame 62 prepared in advance is welded to the square hole. A communication tube fixture 47 and a lighting tube fixture 48 are welded to the inner surface of the second outer tube 21 . A second flange 23 is welded to one end of the second outer tube 21.

The electronic device tube 41, the communication tube 45, and the electric light tube 46 each having a stopper 49 attached to one end are inserted into predetermined holes provided in the communication tube fixture 47 and the electric light tube fixture 48. be done. A stopper 49 is then attached to the other end of these tubes.

A lid is welded to the other end of the second outer tube 21. A transformer fitting 67 is welded to the side surface of the second outer tube 21. A step bolt 19 is attached to the round hole by welding or screw fixing. An opening lid 61 is fixed to the working opening 54 and an opening frame 62 that is not scheduled to be used immediately. An antenna support column 555 is fixed to the upper opening frame 62. Through the above steps, the second pillar 20 is completed. The first pillar 10 is also created using roughly the same procedure.

The first pillar 10 and the second pillar 20 are transported to the installation location of the integrated pillar 30. The cell fixing portion 39 of the first column 10 is fixed to a column attachment cell provided in the electric wire common groove. Furthermore, an anchor bolt is inserted into a hole provided in the base plate 38 to firmly fix the first column 10.

A second pillar 20 is placed on the first pillar 10. By fastening the first flange 13 and the second flange 23, the second pillar 20 is connected to the top of the first pillar 10. With the above steps, installation of the integrated pillar 30 is completed. Note that parts fixed with screws, such as the opening lid 61 and the antenna support column 555, may be attached at the installation site instead of being attached at the factory.

Since there is no need to perform welding work at the installation site, the integrated column 30 can be installed in a relatively short time. After installing the integrated pillar 30 using the standardized first pillar 10 and second pillar 20, various equipment such as electric lights 78, traffic lights 77, first equipment 71 and second equipment 72 can be installed as necessary. Since the operator can attach it, it is possible to provide an integrated pillar 30 that can be used according to the local situation.

Since the first pillar 10 and the second pillar 20 are manufactured separately, there is no need to use a large truck for transporting long objects to transport the equipment necessary for installing the integrated pillar 30. Therefore, the installation cost of the integrated pillar 30 can be reduced.

Note that the integrated pillar 30 may be manufactured in three or more pieces and connected at the installation site. For example, the total length may remain approximately 10 meters, but it may be divided into three pieces. For example, if another pillar with the same length as the second pillar 20 is added, an integrated pillar 30 with a total length of about 15 meters can be installed.

Note that the first pillar 10 and the second pillar 20 may be manufactured in a customized state depending on the use of the integrated pillar 30. For example, the mounting position of the opening frame 62, the number and length of tubes disposed inside, etc. may be changed depending on the application, and the opening frame 62 may be manufactured at a factory.

FIG. 15 shows an example of how the extension opening 651 is used. FIG. 15 shows a state in which the extension opening cover 65 is removed. The cable visible on the right side of FIG. 15 is a cable that extends from the upper side of the extension opening cover 65 toward the electric wire common groove. Two power connectors 17 are housed inside the extension opening 651.

The power connector 17 is, for example, a 100 volt plug and a 200 volt plug. For example, if a wide-area power outage occurs and power is no longer supplied from the power cable in the power supply common channel, a power supply vehicle or electric vehicle can be connected to the power supply connector 17, and the traffic light 77, communication antenna 55, etc. Supply power to equipment necessary for recovery. Note that the use of the extension opening 651 is not limited to that shown in FIG. 15.
