Manlet pit design

Hey Veeky Forums, gym engineer here.
I'm in charge of designing my small local gym's new manlet pit after the last one was completely destroyed in a recent whale attack. We survived, but most of our gym was destroyed and our old pit was completely wrecked. I have some experience in gym restoration but very little in pit design, so I came here for advice.
I came up with a preliminary sketch for the new pit. Pic related, hopefully someone would be able to find and fix any problems with it.

Also, advice would be appreciated on
>making the pit double as a bunker for future invasions
>gym clown-proofing the pit
>designing a secure guard room for the manlet pit, and whether that is a good idea
>designing a harpooning station attached to the gym
Or anything else you think might be useful.

My gym's manlet cutoff is 185cm (6'0.72 for ameriinches), for reference.
All measurements in cm.

Some aesthetic ideas for the manlet pit

>the entire perimeter of the pit will be funhouse mirrors that make you shorter
>Also on the perimeter will be a single neon pink/orange tube elevated off the floor at exactly 6 feet. nobody in this room is taller than this glowing line. Its the only light in the room. the entire pit is lit by the 6 foot high neon light. Its a darker than normal gym.

Looks good!

How will you handle the occasional manlet revolt led by 6'1" manlet-sympathizers?

>wanting to be in the manlet pit

this wont happen

Pit needs to be bigger. A 185cm manlet can easily reach a 200cm ledge, let alone jump for it. 1 pullup and they are out. Pit should be 300cm deep minimum, as we have to take into account that the manlets may form a subhuman ladder to escape.

Pit for manlets to lift, or manlet combat?

Don't fuck about with a half arsed manlet pit. You gotta make sure the fuckers don't get out.

>pic related, is manlet pit at my gym

What units are we dealing with here? 200cm seems about right to keep the manlets under control and confined.

in the movie the raptors got out tho

Oh wait, I didn't read the op, was just looking at your pit specs, looks good an
