今回発生した事象は、伊勢湾岸自動車道 豊田ジャンクションから豊田南インターチェンジ間の上郷大成高架橋において、環境対策として追加設置した「あと施工の床版下面吹付コンクリート」がはく離し、高速道路敷地内に落下したものです。
We sincerely apologize for causing a great deal of concern to our neighbors in the event that occurred on the Isewan Isewangan Expwy that we manage.
The location of the incident was surrounded by a sound insulation wall and was not accessible from the outside, and there was no damage to third parties. In addition, we have confirmed that there is no damage that could affect the bridge itself, and there will be no effect on driving to customers using the Isewangan Expwy.
As a result of these environmental measures, only the Kamigo Taisei Viaduct and two Kariya Viaducts on the same Isewangan Expwy have been constructed with spray concrete on the bottom surface of the floor to increase the thickness to more than 200 mm. Temporary receiving stands are installed at all locations to ensure safety.
See document 1-2.
Based on this fall event, the Investigation and Investigation Committee was established on September 16 in order to investigate the cause of the fall and to examine the future response policy from a technical and professional standpoint.
At the 1st Investigation and Study Committee, after confirming the facts of the event that occurred this time,
- Further investigation is needed to identify the cause,
- The characteristics of this event are that the concrete with thickened underside of the floor slab is particularly thick, and that the reinforcement is held with high strength concrete by using metal anchors and sprayed concrete is used for thickening.

[Tomei intensive construction]
Next is the news about Tomei intensive construction.
The press release has already been announced on August 15, but it will be announced again as the date and time are approaching.
This year, we will carry out intensive construction in three weeks from October 20th to November 7th.
In intensive construction, we will carry out construction such as road surface repairs including a 3-Year Plan for Improving Safety, repairs of bridges and tunnels, and measures to prevent signs from falling.
The difference from the intensive work up to last year is that it has been extended from two weeks to three weeks.
The amount of construction work is increasing to carry out the three-year plan, and the two-lane expressway between the Tokyo Interchange and Gotemba Junction, which causes heavy traffic congestion, is restricted only at night when traffic is relatively light, so this section is We are planning 3 weeks.
We apologize for any inconvenience caused by congestion and congestion during the construction period, but by concentrating the work in a short period of time, the number of construction works per year is reduced by approximately 40%, and the traffic congestion time is reduced by approximately 50%. To do. Please check the Tomei intensive construction leaflet for detailed construction details.
Thank you for your understanding and cooperation.
[Status of reverse running and future countermeasures]
The press releases have been announced by 6 companies related to the Expressway on September 10, but I would like to explain the situation of reverse running on the Expressway and future measures.

It has become.
Based on this analysis, we will implement countermeasures at six locations in our jurisdiction where reverse running occurs multiple times this year.
At the six interchange junctions of interest,

- Improved visibility by installing a warning sign
- Physical reverse running prevention measures such as U-turn prevention rubber poles
Implement measures such as
We would like to ask the members of the mass media to help us in communicating how to avoid reverse vehicles and how to avoid them.
Specifically, if you call the staff at the toll gate, the emergency call on the main line or in the service area / parking area, or the road emergency dial (# 9910), you will be notified on the information board and highway radio that there is a reverse running vehicle. I will.
Reverse-running vehicles also tend to drive in the overtaking lane. If there is information about the reverse vehicle on the information board or highway radio, slow down the vehicle and take a sufficient distance to drive on the leftmost side of the traffic zone. Please let us know so that you can stop in a different place and avoid a collision.
The "Autumn National Traffic Safety Campaign" will be held from Sunday, September 21st to Tuesday, September 30th.
As part of our efforts, we plan traffic safety events at 38 locations, including service areas and parking areas in our area.
We are also working on "prevention of reverse running" as a priority educational item, so please cooperate in safe driving.
Unfortunately, yesterday, September 17, there was an accident in which a driver who got off a stopped vehicle on the Isewangan Expwy was hit by a following vehicle and died.

[New Shin-Tomei Expressway Aichi Prefecture section name decision]
Next, we will announce the names of two interchanges and two rest facilities for the Aichi prefecture section Shin-Tomei Expressway, which is under construction for opening at the end of FY2015.
Aichi Prefecture Shinshiro the IC provided in the City "Shinshiro (Shinjo) Interchange".
"Okazaki Higashi Interchange" is located in Okazaki City, Aichi Prefecture.
The Nagano Shitarahara parking area is a PA located in Shinshiro City, Aichi Prefecture.
The SA established in Okazaki City, Aichi Prefecture has been decided to be the "Okazaki Service Area."
These names were decided through discussions with local governments along the lines and procedures with related organizations, as they are easy to understand and simple, clearly indicate the location, and familiar to customers.
With this announcement, we would like the media to be covered by public relations magazines of prefectures and cities, and we hope that all of our customers and local residents will familiarize themselves with these names.
We ask for your continued understanding and cooperation in the construction of Shin-Tomei Expressway Tomei.
These are the topics we have prepared today.
[Moderator]
Now, we are ready to receive your questions.
[Reporter]
I think it became easier for local people to feel familiar with the new interchange of Shin-Tomei Expressway, but please tell us about your expectations for how you want to use it again.
[President]
Regarding the Shin-Tomei Expressway, I am very sorry that the opening time was delayed by one year. We will continue to work diligently and aim to open it as scheduled. In particular, we will install the Nagashino Shitarahara parking area and Okazaki service area in this section, and we will consider new projects, so I would like to use it greatly. In addition, currently, but has conducted a provisional three-lane operation in Okazaki district of Tokyo, Nagoya, Shin-Tomei Expressway is traffic dispersion of when you opened the current Tomei, because it is expected that congestion is reduced, this point is Shin-Tomei Expressway Aichi Prefecture section At the time of opening of traffic, we plan to restore both the upper and lower lanes to the 2-lane operation before the provisional 3-lane operation.
[Reporter]
What exactly is the new project?
[President]
Once the plan is finalized, we will announce it again. I haven't reached the point where I can announce it specifically, but I would like to devise a project that everyone can enjoy.
[Reporter]
It took 2 weeks from the time of the occurrence to the announcement to the media about the fall of the shotcrete. It is said that it was uploaded to the website immediately, but in the future, if there is such an event, do you have any idea to promptly announce it to the media? Also, do you think that this response was appropriate?
[President]
After the occurrence of the event, we were proceeding with preparations for establishing the committee, such as having an expert check the site for investigating the cause. Since other sprayed concrete remains in the vicinity, it took time to enter the site for the investigation and to temporarily receive the work to secure safety. I think that the main point of the question is that it is enough to post it on the website, but this phenomenon does not affect third parties within a limited range or in the absence of people. Considering that, I announced it on the website the next day. After that, we were able to take safety measures for the adjacent parts, so we held an investigation and review committee together with the site confirmation, and announced the contents yesterday including the details of the investigation. In the future, we would like to announce the progress of the committee at briefings and other occasions.
[Reporter]
Depending on the content of the event, is it all right to release it not only to the website but also to the mass media?
[President]
If there is an impact on a third party or an event that causes concern to you, we take it for granted to announce it promptly.
[Reporter]
Regarding the peeling of sprayed concrete, the committee's opinion is that the feature of this time is that it is a particularly thick part of concrete and that it was thickened using a metal anchor, but the fall of sprayed concrete this time is Do you think it is unique to these limited two bridges? Or, I think that this kind of thickening with shotcrete is being carried out elsewhere, but do you think that it will also affect other things?
[President]
To conclude, I think this one is special. The reason for this is that there is a material in the committee, but it is that the sprayed concrete on the bottom surface of the floor slab is thick, and it is almost the same level as the floor slab. The other is that the opponent is made of precast concrete, which is sprayed on very hard concrete. I think that the character is different from the thin shotcrete of 7 cm or less in general RC floor slabs.
[Reporter]
I hear that tests are done before construction even if it is special, but I think that it was difficult to predict the fall this time, but I understand that it will be investigated by the Exploratory Committee in the future. Or?
[President]
exactly.
[Reporter]
There are 89 reverse runs in Expressway, which is 16% of the national total. Please tell me the breakdown within NEXCO CENTRAL.
[In charge]
Within our jurisdiction, 63 cases 71% were due to people aged 65 and over, 42 cases 47% had a suspicion of dementia and drinking, and 37 cases 42% occurred at night.
[Reporter]
Do you have something unique compared to the whole country?
[In charge]
It shows a similar trend.
[Reporter]
Is it all right to open all lines of Shin-Tomei Expressway in Aichi Prefecture from the "End of March 2016 forecast" announced in July?
[President]
There is no change.
[Moderator]
It seems that the question has been interrupted, so this will end the regular press conference.
