So, we will have a tilt up spot every 1000 feet along a 2000 mile long border, and build cranes that can swing 500+ feet? LMAO.
So, now you need billions in site work and temporary roads made to move the erection (no pun intended) cranes for the wall.
Let's just invade Mexico and make a 20 mile DMZ and free fire border zone 
This whole thing is fantasy land. |
Poured in place means just that... it's poured in the place it remains. That is how the thing would have to be constructed. So that means the forms are vertical, then concrete poured down into them.
Absolutely no tilt up.
You need the rebar sticking out of the footing, into the wall, to get the moment connection into the footing.
They can easily form 12 foot sections (high) and have a cold joint. Wind, seismic, doesn't matter, the wall is self supporting and stands up because of the footing. Which is similar to a spread footing, just wider and with 2 layers of structural reinforcement, not reinforcement simply for crack control. And every 200 feet or so there needs to be a complete and total isolation joint.
Pre-fabbed wall panels have plates that are connected. This connection is at the very, very bottom of the wall. You couldn't get the moment connection so then you would have to create a lot of other support so it stands. These walls work when you have a floor and a ceiling... pin, pin connection. No moment connection required.
