What are these

[idbefishing]

I see these giant metal sorta box thingy at construction sites and always wonder what they’re for

[Axkiker]

digging big holes and keeping it from collapsing on workers

[218_fishing]

Forgot the name, by aren’t those used for digging down and placing them in hole to prevent collapsing side walls?

[smalljawguy]

I believe they are placed in ditches/trenches at construction sites to prevent collapse of the ditch/trench

[kailor]

Those are to keep earth from caving in on a worker(s) while they are working in a deep trench.

[skewby]

To put in ditches while working to prevent injuries in case of a collapse.

[Mullins057]

Those are stabilizing trench walls, keeps the side from caving in on workers.

[Nitrostick]

trench boxes,...placed in trenches/holes when workers are present to prevent a wall from falling in on the workers.

Would it not be considered a type of caisson? Or is a caisson only when retaining water out of a construction site?

[D.O.C. 989]

Cubes for placing in the lake to help with Bass habitat.

[BOATS]

2 MINUTE penalty boxes...….. Seriously, like stated above, metal shoring for trenching.

Naww, they are trench boxes. Most Cassions are used to force water out, these do nothing but stability each side of the trench

And all on topic, who says miracles don't happen

[ECobb91]

They are trench boxes. Used for shield and shoring processes when digging trenches greater than 5’deep. They are used to prevent cave ins and side wall collapse when excavating and working in ditches.
