さてことしの北海道、とくに札幌市は例年の２倍近い積雪深。
ようやく３月に入って雪融けが進んで来てはいましたが、
幹線道路以外の住宅地・中通りは大量積雪と融雪進行で
道路がグチャグチャで毎日雪中陥没のクルマ続出という状況でした。
とくにここ１週間ほどは車両交通について要注意アラートを出して
出入りに注意喚起せざるを得ない状況で推移。
そういうなかでグッドタイミングで3/12-15期間での集中除排雪の告知。
この期間については基本、スタッフにも駐車場出入りを禁止して
市の除排雪作業がスムーズにできるように協力体制。
そういった準備を整えたきのう15日、朝から写真のような専門除排雪車軍団が
弊社前道路に一気投入されました。
前面道路は８ｍ幅で積雪がなければ２車線道路＋歩道各１ｍの合計10ｍ。
ところが降雪の結果、１車線のみ通行可で幅もギリギリ３ｍ程度、
しかも左右の雪山は場所によっては３ｍ超。
すでに人力での作業限界になっていたのです。
札幌市内では春先にはこのような「集中除排雪」が行われますが、
ことしはこの「ありがた」感がハンパない。
やはり公共による交通確保というのは都市機能の基本インフラ。
年間積雪が６ｍ近い世界の大都市というのは札幌が唯一。
日本はこんな積雪寒冷地域でも巨大人口都市を維持してきている。
ふだんはそういう奇跡についてリアリティを持つことは少ないのですが、
この集中除排雪作業には圧倒的な迫力がある。
作業は朝８時頃から午後３時頃まで行われましたが、
まずは巨大雪山の破壊、崩し作業。
そして大量に路面に積層された雪を移動処理する
その後、雪山をさらに掘削してトラックに雪を積み上げ処理する。
路面の残雪除去の作業車はなんども路面を掘削して
アスファルト路面が表出するほどに徹底して除雪してくれる。
その上、各戸敷地との間にできてしまう「段差」についても
可能な限り「平滑化」に努めてくれる。
市民の側としてはできるだけ出入りを少なくして作業環境確保に協力する。
こういう雪深い地域であるのに大都市として
経済活動、人間居住が可能になるためにはこういった除排雪技術が肝要。
見ているとこれら除排雪重機車の運転技能も素晴らしい。
人馬一体というコトバがあるけれど、
マンマシンシステムの妙技にまことに驚かされ、手を打ちたくなる。
こういった仕事文化にも大きく刮目させられます。
日本は北海道が領土になったことで、貴重な技術進化がもたらされたと思うけれど
そして普段は仕事柄、住宅の進化について探究しているけれど、
それもまたこのような基本インフラの運営技術が支えてくれている。
そういうことに思いを深められた１日でした。ありがとうございました。

[Concentrated introduction of various heavy machinery vehicles. World's most advanced city snow removal]
The control of the snow removal vehicle, which is equivalent to that of Jinba Ittai, is excellent. Securing 2 million urban infrastructure in a heavy snowfall area of 6 m per year. Japanese life culture power.・ ・ ・
By the way, this year's Hokkaido, especially Sapporo, has almost twice the snow depth as usual.
The snow was finally melting in March, but
Residential areas and Nakadori other than the arterial roads are subject to heavy snowfall and snowmelt.
The road was messy and the cars were sunk in the snow every day.
Especially for the past week or so, I have issued a caution alert about vehicle traffic.
The situation has changed to call attention to entry and exit.
Under such circumstances, the announcement of intensive snow removal during the period of 3 / 12-15 at good timing.
Basically, staff are prohibited from entering and exiting the parking lot during this period.
Cooperation system so that snow removal work of city can be done smoothly.
On the 15th, when such preparations were made, a specialized snow removal vehicle corps as shown in the photo started in the morning.
It was thrown into the road in front of our company at once.
The front road is 8m wide and if there is no snow, it is a two-lane road + 1m each on the sidewalk, for a total of 10m.
However, as a result of snowfall, only one lane can pass and the width is about 3m.
Moreover, the snowy mountains on the left and right are over 3m depending on the location.
It was already at the limit of manual work.
In Sapporo city, such "intensive snow removal" is performed in early spring,
This "thank you" feeling is not hampered.
After all, securing public transportation is the basic infrastructure of urban functions.
Sapporo is the only major city in the world with an annual snowfall of nearly 6m.
Japan has maintained a huge population city even in such a snowy and cold region.
Usually, I rarely have reality about such a miracle,
This centralized snow removal work is overwhelmingly powerful.
The work was done from about 8 am to 3 pm,
First of all, the destruction and destruction work of a huge snowy mountain.
And a large amount of snow piled up on the road surface is moved and processed.
After that, the snowy mountains are further excavated and the snow is piled up on the truck for processing.
Work vehicles for removing residual snow on the road surface are often excavated on the road surface.
It removes snow so thoroughly that the asphalt road surface is exposed.
In addition, there is also a "step" between each house and the site.
It strives for "smoothing" as much as possible.
Citizens will cooperate in securing a working environment by reducing the number of entrances and exits as much as possible.
Even though it is such a snowy area, as a big city
Such snow removal technology is essential for economic activities and human settlement.
Looking at it, the driving skills of these snow-removing heavy-duty vehicles are also wonderful.
There is something called Jinba Ittai, but
I was really surprised by the feat of the man-machine system and wanted to do something about it.
This kind of work culture also makes a big difference.
I think that the fact that Hokkaido became a territory in Japan brought about valuable technological evolution.
And although I usually explore the evolution of work and housing,
This is also supported by the operating technology of such basic infrastructure.
It was a day that deepened my thoughts on such things. Thank you very much.
