isolate (deviate) flow in an opening tank?
(OP)
Do you know any technology which could be use to deviate fluid in a big fluid receiver open to the air?
I mean the fluid has a flow higher than 6 000 m^3/hour and we don't want to stop the process for going to work on the floor receiver (maintenance). Pressure should be high and we don't want any leak of fluid.
Does it exist a kind of "balloon" technology for isolating a process flow?
Is somebody have try that before?
Thanks for your help!

An other example, it's like to work in the middle of a lake without emptying the lake of its water... And to make walls to permit to the people to work not in the water...
is it much clear?

Will it need ventilation so the people don't have to breathe fumes of the process fluid or the exhaust of whatever power tools you put in it? Consider the issue.
It will probably need flanges or similar features at intermediate points also, because it's externally pressurized by the hydrostatic head and therefore unstable, or quasi-stable, meaning that if it's not strong enough, it will not fail in a graceful way, it will buckle and collapse instantly, with probable loss of life, so it needs to be seriously engineered.
It could be rectangular as drawn, but that will require more reinforcement than a round cylinder would.
Is the process fluid more dense than water? That will affect the pressure at depth on the outside, and needs to be accounted for.
If the cylinder were tapered, smaller end up, i.e. a cone not a tube, that would provide some hydrostatic downforce on the seal, at the expense of some added complexity of fabrication. Speaking of which, there may be load limits intrinsic to the floor that you will have to consider.
For a reservoir large enough to hold a dump truck, earthen cofferdams might be more appropriate, but you haven't so far provided a dimension to tell us the scale of the problem.

Dimension will not be always the because my goal is to repair a "receiver". But the receiver is about 6 ft x 4ft x lenght to determine.
I like your comments that help to think and verify ideas - solutions.
