The most crucial step is that these main bars need to be closely adhered to and pass through the sides of the rebar cages in each pile hole.
Then, Cody and Stan are responsible for placing square stirrups at intervals onto the main bars of the ground beams and begin tying them with tying hooks.
David looked somewhat confused and asked, "George, I see that the reinforcing bars of the ground beams and pile foundations are not directly tied together. Will such a connection be secure?"
Old Qiao glanced at David and then explained, "Good question, kid! This is the mystery of reinforced concrete."
"We don't need to bind every single rebar rigidly; we just need to ensure they interlace spatially! The rebars of the pile foundations are vertical, and those of the ground beams are horizontal, crisscrossing and supporting each other."
"In a moment, when this flowing stone called concrete is poured in, it will fill all the gaps, forming a true whole!"
