Since the pedestrian overpass 1 is extended up to the final refuge place 11 and a plurality of routes of the pedestrian overpass 1 reaching the final refuge place 11 are provided, the person taking refuge can arrive at the final refuge place 11 through one route by himself/herself even if the other route is shut down. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an inundation countermeasure evacuation facility that quickly evacuates nearby residents or street passers to high places when a tsunami or flood occurs, and guides the refugees to a preset evacuation site Is.

  An example of a facility for quickly evacuating residents in a flooded area when a disaster such as a tsunami or flood occurs is a tower-type evacuation facility. This evacuation facility is constructed in advance with a building with a floor surface higher than the surrounding ground. (For example, refer to Patent Document 1 and Patent Document 2).

JP 2004-339920 A Japanese Patent Laid-Open No. 9-184323

In addition, the slant staircase connecting the relay evacuation site and the final evacuation site so that evacuees who have boarded the elevator and evacuated to the tower-type relay evacuation site can evacuate to the final evacuation site at a higher altitude. There is also disclosed a technique provided with (see, for example, FIG. 1 on page 19 of Patent Document 3).
In addition, a huge stilt structure that covers the entire houses in the residential area will be installed so that evacuees can evacuate on the stilts. A technique in which a connecting path for connection is provided is also disclosed (see, for example, FIG. 31 on page 22 of Patent Document 3).

JP 2004-305737 A (page 19, FIG. 1, page 22, FIG. 31)

The so-called tower-type evacuation facilities described in Patent Document 1 and Patent Document 2 described above, especially in the case of a tsunami, have only a short time until the tsunami arrives after the evacuation order is issued. Although the residents of this area can be surely evacuated because the distance to the evacuation facility is short, there may be cases where the evacuation is not in time for residents in areas far from the installation location. Moreover, since the floor area provided in the tower is small, there also exists a problem that many evacuees cannot be accommodated.
For this reason, a method of providing a large number of towers at regular intervals is also conceivable so that all inhabitants can evacuate reliably and a large number of inhabitants can evacuate.

However, since this type of tower is not used at all except in an emergency, such facilities may not be maintained and maintained without security by anyone in daily life.
In addition, if the period required for the flooding or restoration becomes long, it is necessary to evacuate the refugees on each tower to another evacuation site (final evacuation site) where they can have a short-term evacuation life. Can occur. Due to the nature of the flooded area, this re-evacuation often results in a lot of time and effort for those who are engaged in relief activities or the evacuees themselves because the roads are often unusable due to water congestion and various obstacles. .

  In that respect, the evacuation facility described in Patent Document 3 includes a tower-type evacuation facility (relay evacuation site) where the evacuees can move up and down by themselves and the communication path connecting the final evacuation site. By yourself, you can reach the final evacuation site at a high place such as on a mountain outside the flooded area.

However, even in an evacuation facility provided with the communication path, as in the case of Patent Document 1 and Patent Document 2, residents of areas away from the installation location still have a problem that the evacuation is not in time. .
In addition, there remains a problem that these evacuation facilities do not reach the daily routine of anyone, such as maintenance and security maintenance, without being exposed to anyone.
Furthermore, if facilities are destroyed by water pressure, driftwood, etc., and the communication path is cut off, the evacuees cannot reach the final evacuation site by themselves.

  Therefore, the present invention has a first problem of ensuring that residents in a wide area can evacuate reliably, a second problem that the facility is well-maintained in daily management, and further destruction. The third task is to enable evacuees to reach the final evacuation site on their own even if the communication route is cut off due to the above.

In order to solve the first problem, the present invention provides a long pedestrian bridge along a street and a lifting facility that allows a person to go up and down at an appropriate position in the middle of the pedestrian bridge.
In general, streets cover a wide range of residential areas like a mesh, so if you set up a pedestrian bridge along the street so that you can ascend from any area to the pedestrian bridge, residents of a wide area Will be able to evacuate to high places where water cannot reach.
In this way, when a street is difficult to pass due to various obstacles such as water stagnation and drifting objects, it is easy to access each affected area through the pedestrian bridge without using the street. The effect that it is possible can also be exhibited.

Next, in order to solve the second problem, the present invention uses a footbridge provided along the street as an everyday passage.
In this way, the evacuation facility that is long along the street functions as a pedestrian passage that can move in the lateral direction, a so-called pedestrian deck (pedestrian mall), so that many people always come and go. If many people come and go, security can be maintained, and if the facility is touched by many people, maintenance can be easily accomplished and daily management can be facilitated.

Furthermore, in order to solve the third problem, the present invention extends the pedestrian bridge provided along the street to the final evacuation site and provides a plurality of pedestrian bridge routes leading to the final evacuation site.
In this way, even if the connection route of one route is cut off due to water pressure, driftwood or the like, the refugee can reach the final evacuation site by himself / herself through the connection route of another route.

  In this invention, a long pedestrian bridge is provided along the street, and an elevating facility is provided at an appropriate position in the middle of the pedestrian bridge, so that residents in a wide area can be evacuated reliably, and the street is not accessible by the disaster. Even when it is difficult, each disaster area can be easily accessed. In addition, since the footbridge provided along the street is used as a daily passage, the facility is well-maintained for daily management. In addition, the pedestrian bridge provided along the street is extended to the final evacuation site, and multiple routes to the final evacuation site are provided. Can be reached on your own.

An embodiment will be described with reference to FIGS. 1 to 3.
As shown in FIG. 1, the inundation countermeasure network evacuation facility according to this embodiment includes a pedestrian bridge 1 through which light vehicles such as people and bicycles can pass along streets 10 arranged in a grid pattern in an urban area. Similarly, they are arranged in a lattice pattern.

  This pedestrian bridge 1 is constructed by building a large number of columns 3 on the sidewalk of the street 10 and supporting the floor slab with the columns 3 to form a passage 5. The floor slab is provided at a height that does not impede the architectural limit of the street 10 and higher than the expected flooding height, and appropriate balustrades 4 are provided on both sides of the passage 5. In this embodiment, the pedestrian bridge 1 is provided above the sidewalk of the street 10, but may be provided above the roadway as long as it does not interfere with automobile traffic.

The pedestrian bridge 1 is provided with elevating facilities 2 at which a person can go up and down. For example, the code | symbol 21 shown in FIG. 1 is a staircase, and the code | symbol 22 is an elevator.
Since the street 10 covers the city area widely like a mesh, it is possible to rise from any area along the street 10 onto the pedestrian bridge 1 using the lifting facility 2. Therefore, inhabitants, passersby, etc. in a wide area can evacuate quickly and reliably on the passage 5 having a height that does not reach the water at the time of flooding.

  Further, as shown in FIG. 2, the pedestrian bridge 1 is connected to two or more floors of a roadside building 12 via a pedestrian bridge 1 ′ in the crossing direction of the road. This floor is a floor having a floor surface that is higher than the expected flooding height. Since the building 12 is provided with a stairs 23, the stairs 23 functions as the elevating facility 2.

  Since this pedestrian bridge 1,1 'and the above-mentioned lifting facility 2 etc. are opened not only in the event of a disaster but also in a state where people can always use them, this evacuation facility is a pedestrian separation type that covers the entire city area. Functions as a network passage. Therefore, many people come and go on this passage 5 every day. If it is a facility where many people come and go, daily management of the facility can be facilitated.

Further, as shown in FIG. 1, the pedestrian bridge 1 extends to a final evacuation site 11 provided in a mountain that is outside the expected inundation area. A plurality of routes of the pedestrian bridge 1 leading to the final evacuation site 11 are provided from specific positions along the pedestrian bridge 1.
For example, as shown in FIG. 1, since there are three pedestrian bridges 1 for routes A, B, and C, one of these pedestrian bridges 1 is caused by water pressure at the time of flooding, drifting objects such as driftwood, etc. Even if the vehicle is destroyed and cannot pass, the evacuees can reach the final evacuation site 11 through the footbridge 1 of a route different from the destroyed route.

  Also, especially in the case of flooding disasters, roads (street 10) are often difficult to pass due to various obstructions such as stagnant water and the above-mentioned drifting objects. For those engaged in relief and restoration activities, Access is very time consuming and labor intensive. However, if there is a long pedestrian bridge 1 along the street 10 and there is an elevating facility 2 where a person can go up and down at an appropriate position in the middle of the pedestrian bridge 1, even if the street 10 is difficult to pass, Without using the street 10, it is possible to access the affected areas scattered over the pedestrian bridge 1.

  In addition, the inundation countermeasure network evacuation facility of this embodiment has an observatory 13 having an artificial ground 13a whose footbridge 1 is located higher than the street 10 via the footbridge 1 'as shown in FIG. It is connected. The observation deck 13 is constructed to have a strength that can withstand a large water pressure caused by a tsunami or the like.

The observatory 13 includes a slope 14 that allows an automobile to move up and down between the street 10 and the artificial ground 13a. For example, when an earthquake occurs or a tsunami warning is issued, the observatory 13 passes through the street 10. It is also possible for the automobile M to evacuate on the observation deck 13.
In addition, the observation deck 13 is provided with a commercial facility 15, and the commercial facility 15 is also constructed to have a strength that can withstand a large water pressure caused by a tsunami or the like. Can be used for the supply of food and public health necessary for living in refuge. In addition, during normal times except during disasters, it is possible to attract tourists to the observation deck 13 and activate the area.
For example, the observation deck 13 is arranged along the sea, the commercial facility 15 is Fisherman's Wharf, and there are facilities for selling marine products, crafts, special products, etc., or eating and drinking facilities in the facility. Use as a spot. In the event of a disaster, the facility can be used to prepare and provide meals for evacuees, and it can also be used for public health with hot spring facilities or toilets that can be used in the event of a disaster.
