【ポンプ打設】ひっきりなしに圧送される生コンを捌いていくプロの技【河川改良工事-Part.3】

Hello!
We, MKproject , are a company that undertakes general civil engineering work.

Although we are a small company
I have devoted myself to civil engineering for 30 years.

I started posting videos with the feeling that I would like overseas people to see Japanese civil engineering technology.
