It's important even if it's small! What is under the lid of the city?


Hello. I'm Hanes, an active correspondent.
It's been completely autumn, but the days of moving while lowering your eyes continue without letting go of the parasol.
At that time, what you see is a manhole cover or a manhole cover installed on the sidewalk.

I often see sewer-related manhole covers of rainwater, sewage, and confluence, but in fact there are various other equipment lids.
Moss' article "Let's walk down! A lid engraved with "City Light" that was introduced in the slightly mysterious "City Light" lid, a joint ditch lid featured in the article "Chuo-ku Underground" in April 2018, and engraved with "Light" One of them is the lid for wiring of street lights.

When it comes to wiring lids, the trees in Chuo-ku and the azaleas in Chuo-ku, which Mr. yaz introduced in the Manhole in Chuo-ku, are depicted, and as shown in the photo above. Some of the ward chapters contain the word "light" in the Chuo-ku.
The latter is located right next to the streetlights in Tsukuda Park, so you can find it right away.

In addition, there is a lid indicating a manhole that can be used as a toilet in the event of a disaster that has been introduced several times so far.

The role is different from the lid, but as introduced in the April 2020 article "Romance Created by Points and Points-Chuo-ku and Survey-", "Tokyo Metropolitan Standard Base" and "Standard Points" related to surveying are also Chuo-ku Dotted in!

In addition, there is also a lid on the water outlet that will be newly featured this time.
I have shown the inside in photos before, etc., but inside contains related equipment such as buried pipes.

This lid, located in the city of Nihonbashi, is located between 1941 and 2004, along with the logo of the Teito Expressway Transportation Corps (currently Tokyo Metro Co., Ltd.), which has reached its 80th anniversary last year. It is engraved as "Consolidated water pipe water outlet for firefighting".
In the event of a fire at the subway station, it is thought that it was installed to send water from here.

In addition, near Eitai Bridge, we found a lid of the water outlet engraved with "Water spray fire extinguisher fire brigade water supply port Tokyo Electric Power Company"!
Whether it is the lid of the Teito Expressway Transportation Corps mentioned above or this lid, you can see the age from the company name and the kanji used.
It is said that there is a sprinkler-like facility that emits water in the form of fog here.

About water outlet in Chuo-ku, please see article "Chuo-ku (the first part) to see in history of firefighting" of July, 2018, "Chuo-ku to see in history of firefighting (the second part)".

The lids in the city tend to be bundled with "manholes", but if you take a closer look, you will notice that there is a different role than you expected.
At the same time, we also found that what is contained under the lid is always an important equipment that supports and helps us in an emergency.
Before the day of disaster prevention on September 1, I would like to thank once again for their facilities scattered throughout the city to live with peace of mind.
