How this node works
A capping beam links the pile heads and spreads the load; through it an inclined tie-back reaches back into the stable ground, where a grouted bulb anchors it. Stressed, it pulls the head of the wall back against the thrust — its free length must reach past the failure wedge to the firm ground beyond.
