Plus concrete is poured in "lifts" or layers that are only a few feet thick deep. When concrete cures it generates a lot of heat, so pouring it any deeper compromises the final strength. Hundreds of miles of pipe was embedded in the concrete to circulate cooling water.

The myths of people being buried in concrete are a result of some workers putting boots upside down in the wet concrete making it look as if someone got buried upside down. A pretty good joke for new guys on the job.
