Dude. You are trying to nigger rig a retaining wall.

Don't. Don't reinvent the wheel.

Look up retaining wall constructions.

Also, you don't put a plastic sheet like that, it won't drain like that.

Also, your drawing means fuck all without proper dimensioning. Information on ground condition and nearby vegetation will be important also.

my original idea was to just build a big concrete form and do a massive concrete block

>>1094000

would I be better off just splitting the base into two 5' walls instead?

Don't guess this shit. You need real engineering advice.

>>1094026
This. Not saying don't do it yourself, just don't engineer it yourself.

This is what you sound like. No offence.

>Be building a car, I have drawn up a square wheel with rounded corners. Also, shoe strings to turn the wheels.
>No man it won't work like that.
>My original idea is just to make a massive iron ball for the wheels.
>Would I be better off making the rounded squares into rounded hexagons instead?

You are talking complete worthless shit.

are right.

You are clearly not in the game and don't know what you are doing. For real. There are codes and regulations about this sort of thing, and if you are gonna nigger rig it, at least go study some shit. Now you are going full retard just farting shit out of your ass. Go do your homework, or pay someone to do your homework. Don't not do homeworks.

This

A concrete wall

Put up a plywood mold and do it

Well op your plan looks pretty rubbish I'm sorry. Don't you have building regulations for this type of thing?
Rule of thumb is retaining wall should be four times as thick as it is high, but the caveat is that you can treat the layers separately, so a 4ft high retaining wall the first foot should be 1ft thick, the next ft only needs to be 3/4ft thick etc etc so out thins out at the top a little bit.
If you want to build up past the top of the retained soil then just keep building it up don't start a new wall ffs. I wouldn't lay a foundation on gravel for draining either!
Backfill with 10mm gravel min it equivalent and get rid of that weird drain pipe, you need pipes running through the wall, several spaced along the length of the wall. The spacing between and diameter of the pipe needs to be calculated, again you should check your local building codes they will tell you all this shit.
At the end of the day of something has to be built someone will have made rules to fine you for breaking. Sounds like fun police right except its also a great resource as to how to do it properly.

Engineer here.
Restraining structures make us lose sleep at night.

DO NOT cheap out or try to """""engineer""""" it yourself. Especially if you don't know shit like rankine soil pressure coefficients off the top of your head.

Retaining structures*

THIS.

Another engineer here. If this shit is over 1m tall I would definitely consult a professional. It sounds stupid but these things can kill or seriously hurt people if you fuck this up.

Just noticed it is a 10 foot tall retaining wall.
Definitely do not do this yourself.

This is a pretty sizable even for reinforced concrete. A standard concrete core filled block wall may not even be strong enough to retain the soil.
