Concrete panels for slurry channels

I have a slatted tank to do around where 3 robots are going
About 24m long and 4m wide but only 1m deep
Tight site up against another building
Thinking of panels for sides then dig middle out and concrete floor and concrete round top to sit panels on
Thinking that by the time set up shutters etc panel walls could be up and finished and would be cheaper overall

The problem will be trying to cater for the surcharge trying to push the sides in when you drive a tractor over them. If placed longways the reinforcing will be the wrong way too.

double loaded 150mm panels?

my thoughts would be set the panels onto steelwork then concrete the base allowing it to run under panels and setting a slope on it? you may have to set panels inside H sections for loading both ways ie soil pushing inwards and slurry pushing out?
 
I thought that after writing it. the load would only be pushing in I was thinking the slurry would weigh/ push back as in a tank but hopefully it wouldn't be that full and the soil will equal it so as you say single loaded ok.
but steel in with slurry is that corrosion waiting to happen?

Yeah that's what has always put me off. And sealing it up properly as well

Aren't there one or two unknowns here? Is the pessure in from the back fill,or out from the slurry? How do you calculate the outward pressure from slurry? It has no weight on the concrere floor which could act as a toe, so once the panels started pushing outwards, there would only be the soil outside to take the pressure, but that will presumably be back fill so can it take any pressure at all? OK so you don't intend driving tractors near it, but what effect will a 600kg cow have when you are chasing it and it decides to stop suddenly? What about the concrete floor which will in theory, be unsupported, so an overhang next to the edge of the channel. Have you included enough reinforcement? Of course sealing it is likely to be a problem, and how are you going to protect the supporting steel from corrosion? Any below ground level slurry store has to have a design life of 20 years without maintenance. Sadly, regulations are brought in to protect us from the mistakes made by amateurs, but make it harder for professionals to conform and do their job efficiently and economically.

Most slurry channels in the last 40 years have been built with concrete blocks filled with concrete or not Which I feel will not be as strong as 140 mm precast concrete panels made out of rc50 concrete
This is only one idea of construction of a channel one metre in depth with surrounded floors tied into the walls
I have been doing groundworks and construction for over 25 years so don't think I class as amateur
