Urgent help - disaster during pour, cold joints
Urgent help - disaster during pour, cold joints
(OP)
Need some advice from fellow engineers or concreters.
Was pouring concrete for some reinforced footings for a retaining wall when the concrete truck, which has been unloaded and pouring along side the job, ending up in the trench/reo we were working on. The idiot tried to drive out instead of reversing back the way he came in, went too close to the trench, it collapse and he got bogged within the reo. Obviously, we couldn't fix the reo and formwork so the pour was cancelled.
Now, we're left with a half poured footing, with the end (the last point of pour) only halfway to the finished level with reo still exposed. I don't want a cold joint since it is load bearing and I don't exactly want to waste more time, man power and hiring an hammer/excavator and rip out what we've already done and redo the whole thing.
Any suggestions or even better, solutions?

Have the designer check shear friction. If it works, you might have to roughen the top surface of the concrete.

Hey I hope your ego won't get in the way as mine did under a similar circumstance but i have to agree with UK on this one. As a super or foreman or whatever you need to take responsibility for the accident. I had a sugar sand trench callapse and although I had proper shoring and no one got hurt it took more than enough time for me to realize that I lucked out and no matter what it took, it was my job to make sure that didn't happen and I failed. It was on me and someone could have died. After I owned that, I became a better ...........I don't know, manager?
Accidents don't just happen
they can be avoided with enough due dilligence
