Thanks, I had never even wondered how these were made. Definitely a young persons job, but hard to imagine how else it could be done, very hard working operatives in a very difficult environment. I have worked in a cement kiln plant, it is hard, dusty, noisy, but we all appreciate the fruits of their labour.
Whenever is see these factories, i always think, what they would look like when they were brand new. All of the colors, that are now chipped and faded. Must have been pretty ^^
great video! I wonder what brand of concrete is used in the manufacture of concrete rings? I was embarrassed that the reinforcement was welded, usually in reinforced concrete products they are connected with wire.😮
@@MAXProcess Remesh is welded. As far as I'm aware there is nothing wrong with welding metal concrete reinforcement. I'm just wondering why you are "embarrassed" by the fact that they weld the rebar in this video.
Rebar is NOT for taking up compression forces (1:58) but for taking stress forces. Concrete can handle large compression force without rebar, but almost no stress forces. So the steel takes up the stress forces.
They did not say that it does. They specify that the rebar being added allows the concrete to be resistance to compresson and impact. Although Concrete can support a lot of compression, it can fracture apart from that constant load over time and rebar helps keep it from fracturing apart allowing to continue to support the compression force. Thats why they added the "and impact" part because of bridges and road ways suffering impact stress of vehicles going on and off along with the vibration they can impose which leads to fracturing of concrete.
O presidente Bolsonaro disse que nunca viu um japonês no Brasil passar necessidades básicas, porque os japoneses tem valores muito bem firmados, são obedientes e disciplinados, parabéns.. que Deus abençoe está nação.
I find these videos fascinating. They must be encouraged somehow by some Japanese Government Branch to highlight the country manufacturing traditions and capabilities. Having watched many of them I am struck as to how relative small and diverses these companies are, including where they are located. It seems factories in Japan are widespread trough the country and that they are fully integrated within their environement. This is country I could like, they got it right.
Quá đẹp, chất lượng tốt quá, người việt nên học hỏi nhiều hơn ở người nhật, rất tiếc những người làm công trình xây dựng lại chả mấy người quan tâm đến chất lượng, mà chỉ lo làm xong thu về được bao nhiêu tiền,
Dentro de años la visitare y me acordare que en uno años trabaje en eso ... Si eso lo ve en ribas dentro de años se pega un susto es un trozo de su vida del pasado .....pero como vivirá mejor solo sera un trozo agradable del pasado Tiene una utilidad al ribas le puede recordar ser mortal y no le gustará muche estar mas de tees horas viendolo solo un pico y chao Despertar soñando dentro de un sueño

REALLY!!!! So what you are saying is that they they should make a form for every different type of pipe. Say you need a pipe with four holes, make a form with four holes, three holes on the pipe make another form. How much money?? How much time. 😵💫😵💫😵💫
@@yeagerxp ---yes, they should have different forms, if they were intelligent, they could figure it out. This is the 21st-century, wherever there’s money to be made, they should make it. It’s better than spending all day drilling into cast concrete.
This is underappreciated work.
日本の地下で、縁の下の力持ちをしている、暮らしを守るマンホールはこうやって作られるのですね。
意外と手作業の職人によるお仕事もあって驚きでした

صباح القوة والنشاط مع اليابان شكرا لك على تعبك شكرا 😊😊😊😊😊👋👋👋👋🎉🎉🎉🎉🎉🎉🎉
Japanese people are excellent. We love you from Turkey 🇯🇵🇹🇷
プロセスX
👍👍👍
コンクリートのマンホール工場とのことで、同じ材料で「蓋」も作るのかなと思ったら「本体」を作る工場だったんですね。打設の瞬間を見ながら、嗚呼こうやってあの鋼鉄の丸い蓋の下は作られていくんだ…と深い感慨を覚えました。底を拵えるインバートと呼ばれる加工が、モルタルの砂を詰めて作っていたのは初めて知りました。
インバートは型枠で成型して最初から一体で作る事自体は可能です。
後から打ち足しているのは、本体（底盤）を受注生産するんじゃなくて、繁忙期や閑散期に関係なく見込み生産しておいて
製作済の本体に対して受注が入ってから図面に合わせて加工する販売方法を取っているからです。
最初から受注生産しかしていない製品（ただし割高です）なら開口も後から削孔（コア抜き）するんじゃなくて、コンクリート成型時に抜き型で開口する製品もあります。
プレキャストコンクリート屋
マンホールは工場製造と現場製作の2つがありますね、インバートは現場で作る事もありますね。
Gyönyörű. Magyarországról vagyok.
Really well made! Quality and care of the tools!
Well done . Informative 👍👍👍. Thank you for sharing. Be safe🇨🇦
First time I see the steel rebars clean and not incredibly rusty
That looks like a premium product
安定した需要があって景気には左右されないから安心して仕事できますね
Such a shiney truck.

깔끔하게 잘 만드네요.. 역시 일본의 기술
結構アナログな感じで作ってて面白かったｗ
Nhìn sắt thép bên trong là biết vô cùng chất lượng. Người Nhật làm ăn khỏi lo 🇯🇵👍.
Beautiful concrete factory
First time seeing a concrete factory the quality of what you made is good 🙂✌️
What a wonderful concrete factory
Nhà máy làm hố ga bê tông của Nhật Bản rất tuyệt vời. Nhật Bản OK 🇯🇵👍.
Vos vidéos sont toujours intéressantes, merci!
技術の固まりですね
Iam from Indonesia, mmm after see this . Wuhhh, this great... Kerja bagus
Schön und gute Arbeit
Jau Jürgen, ein japanisches Video auf einer englischen Plattform. Und was macht der Deutsche? Gibt nen Kommentar ab und zwar auf Deutsch!
этот процесс мне знаком!👍👌
12:57 I'd like to know more about that "invert machining." I'd like to know how they got the surface to be so smooth. and how they formed it.
great video! I wonder what brand of concrete is used in the manufacture of concrete rings? I was embarrassed that the reinforcement was welded, usually in reinforced concrete products they are connected with wire.😮

日本は地震が多いので強度を他の国より上げる必要からだと考えます。
What's wrong with welding?
@@firecloud77 Usually when you put rebar in concrete, it is not welded, but tied together.
@@MAXProcess Remesh is welded. As far as I'm aware there is nothing wrong with welding metal concrete reinforcement. I'm just wondering why you are "embarrassed" by the fact that they weld the rebar in this video.
@@firecloud77 I think he meant "impressed"
Wonderful concrete factory
Being a civilian I have absolutely no use for any of this and yet I want to buy one!
عمل رائع جدا
Cette usine a été modernisé, avec la mise en place d' automates, mais l'homme a toujours conservé sa place et c'est très bien comme ça.
mais a quoi ca sert .

Where was the rebar used, I missed it?
Do you know what is the maximum load this kind of culvert will handle before it will break or crack?@@silentferret1049
Прекрасное производство!
جميل جدأ
This method is great in manhole construction.
Japan good
Does your company have any plans to produce concrete pipe, if so, we will provide you with the best equipment.
Graet

ISSO NÃO É BUEIRO, É CAIXA DE PASSAGEM DE CONCRETO. OBRIGADO PELO VÍDEO
Great Job Workers !!
What educational video
Muy bien
O es una imagen que te entra o cuela de un pasado real y la ves en un suelo agradable .. para el ribas o los xirgus o el jose rubau ...
Quá đẹp, chất lượng tốt quá, người việt nên học hỏi nhiều hơn ở người nhật, rất tiếc những người làm công trình xây dựng lại chả mấy người quan tâm đến chất lượng, mà chỉ lo làm xong thu về được bao nhiêu tiền,
Bởi vậy công trình của họ mới bền vững hàng trăm năm. Ko như VN vừa làm xong đã hỏng

What is the maximum load this concrete will handle?
КОГДА ПЕРЕЕЗЖАЕШЬ ВМЕСТЕ ЭТИ КОЛЬЦА ЗАБРАТЬ ПРИДЕТСЯ 😂

どれ位の大きさまで作るのですか?電話線用のでっかいマンホールを作ってました。
Eso cuando se coloque de nuevo e marcha seguramente tendra alguna hierva en muchos rincones
Es mejor dejarla crecer para notar el tiempo pasado ya que se vivirá en Japón sin notar el tiempo casi.....
Eso sirbe para recordar la vida pasada ara que esta apunto de cambiar
Εξαιρετική δουλειά!
What about the rebar? Where did that go?
increible
How long do you have to wait for the concrete to harden up safely?
Khác VN với hàn quốc...
Nó ko buộc dây sắt..
Nó hàn đổ dày 😅😂
Simplesmente perfeito
Сколько времени находится бетон в формах? Судя на текучесть бетона не менее двух-трех дней. У нас кольца заливают полусухим раствором вибрированием и сразу снимается опалубка.

I wonder exactly how many dead bodies there are encased in concrete . Or perhaps just limbs. Or even just an eyelash or a nipple. Good day.
Где паровые камеры?
日本不用塑料检查井吗？
工业怕品做成了艺术品。
アーマチュアにプリテンションがかかっていませんか?
本当に外野の素人の感想なんだけど、もう少し作業環境良くすれば生産効率上がりそうに見えるけど。まーこれで採算とれてそうだから問題ないのかな？余計なお世話でした。
１：サイズが大きく重量が有る為輸送費を考慮すると全国展開は無理です。
２：共通規格はマンホール部の口径と継ぎ手のサイズだけで後は現場測量に依るほぼ一品物に成ります。（継ぎ手の位置個数）
３：コンクリート固化の性質上恒温室で固化させても早く成る訳では無い。
４：上記1〜3から顧客は公共工事が主で少量多品種の発注に成る為、大量生産の必要が無い、寧ろその設備導入は企業コストを圧迫して倒産する恐れが有る。
以上が理由です。
いやその通りですよ。
マンホールを作っている会社としては業界1位のプレキャスト屋で、工場の職人のリーダーをやってます。
流石にこの動画の様な、簡単な誰にでも作れる製品だけでは儲からないから、設備にも人にも投資するだけ時間と金の無駄と言えなくありませんが…
収益性の高い製品を作るにはそれなりの作業環境も必要です。
この動画の製品みたいに小さい製品じゃないから輸送ももっと大変ですが、高く売って更に高い輸送費を掛けてでも売れる物は売れています。
1つの工場からバカ高い運賃を掛けて特車のトレーラーで全国に出荷しています。
何故なら、全国で私しか作れない物が沢山あるからです。
弊社の各工場にもそれぞれ違うラインナップの他社では作れない製品を作るエキスパートを配置しています。
勿論、複雑で納期が短くて同業他社が尻込みする様な物ですから、作るのも難しいですよ、仕事はそれなりに厳しいです。
10人雇っても9人は使い物になりません。
この動画に出演されている従業員さんも、うちの工場では一人も生き残れないと思います。
8:17 悲しいことに日本は粉塵対策が甘いと思う

Why do they CUT the hole instead of casting the hole? It would be easier to cast it.
