No.116 Iwabuchi lock(Arakawa spilway)
(It is the Tokyo guide to introduce by the image and the column).
Old Iwabuchi lock with red clear color
Iwabuchi lock is indispensable facilities when thinking of the riparian
work in the Metropolitan area.
Lower reach present Sumidagawa had caused a flood in the Metropolitan area
from Iwabuchi lock every time he was the main stream of Arakawa in the
past and it rained heavily. Therefore, the spilway to have made with 1911
artificially newly to do flood control is present Arakawa (the spilway).
In other words, about 22-km Arakawa is a completely artificially made river
from Iwabuchi lock to the estuary. When looking at Arakawa bank, it must
actually feel not to be the one that the runway with well-proportioned
line to be too refreshed came by the natural result. For this construction,
it bought 1068-ha land and about 1300 houses moved.
In case of the spilway completion, the lock which was prepared for the
fork in new Arakawahousuiro and at Arakawa (現 Sumidagawa) which was a
main stream is "Iwabuchi lock". The gate with 9-m width is pricking
5 gates of red locks and the No. only 5 lock on the side of the rightmost
shore becomes a high big type with height. Water became able to be led
to Arakawahousuiro where there is flowability, preventing inflow to Sumidagawa
with this lock when it rains heavily and the flood in the Metropolitan
area got to run out.
However, after that, by the up of the obsoleteness and the ability at the
facilities to adjust a flood, new Iwabuchi lock was constructed from 1975,
the new blue lock of the color was complete in 1982 and the role of the
feature was taken over. It ended old Iwabuchi lock and duty, but the value
as the engineering works inheritance is in the high thing, too, approaches
to be imminent in service around and at present of being saved and the
lock in the past can be looked at.
