00:00What are the counter gates? We have already prepared two counter gates.
00:05The weight is 17 tons.
00:08Generally, it is not necessary to lower the gate.
00:12So, even if the counter weight is lowered, we can successfully lower the gates when the flood occurs.
00:19But when the flood occurs, in order to raise the gates, the counter weight is necessary.
00:24This is 17 tons.
00:26In the past, we used concrete to raise the gates.
00:31But now, we are using iron to raise the gates.
00:38We have constructed 4.5 tons of concrete with iron.
00:45We are using the same concrete and iron to raise the gates.
00:51The weight of the concrete is 17 tons.
00:54So, we are using the same concrete and iron to raise the gates.
00:59We are also using the latest technology to raise the gates.
01:03Once the concrete work is done, the gates will be raised.
01:10Once the concrete work is done, the gates will be raised.
01:13Then, the boats will be removed.
01:18Five boats came here that day.
01:24We are still waiting for their response.
