Last year, in Chofu City, Tokyo, a briefing session was held on the night of the 17th about the results of a ground survey conducted by the East Nippon Expressway due to the problem of road collapses and underground cavities being found one after another, and residents questioned the results. Voices came one after another.
The company said that it is undeniable that the vibration of the construction caused damage to the house, and stated that it would conduct additional investigations as necessary.
The briefing session held in Chofu City was attended by about 50 residents, including the East Nippon Expressway, which had a tunnel construction deep underground, which is thought to be the cause of road collapse and underground cavities.
On the 14th of this month, the East Nippon Expressway announced the opinion that "the fact that the vibration of the construction weakened the ground was not confirmed" regarding the ground survey conducted outside the tunnel, and was in charge of the briefing session. Explained in detail.
Residents said, "The damage to the house has spread beyond just above the tunnel, and it is inconsistent with the survey results." Isn't it inaccurate? "
In response, the person in charge at the company replied, "We will conduct additional investigations as necessary," saying that the possibility of damage to the house due to the vibration of the construction work cannot be denied.
Haruko Kawamura, a resident, said, "I think it was a conclusion-based investigation without a clear explanation of the causal relationship between housing damage other than directly above and the vibration of construction work. I want you to do it. "
The briefing session will be held on the 18th.
