Manual bored pile, no bearing platform only ground beam pile reinforcement anchorage is not enough how to do

What does the owner mean by insufficient anchorage? Whose reinforcement is anchored into whom? The concept should be clear!

No bearing platform of the grouted pile, should be the column reinforcement anchored into the pile, the column of the inserted bar how can not be anchored long enough? The 35d left at the top of the pile in the plans is for tie-in with the bearing, not "anchoring"!

No bearing platform grouted piles, nodes only column reinforcement anchored into the pile and ground beam reinforcement anchored into the pile. Piles are the foundation of columns and beams, not columns and beams for the foundation of piles, is not the cart before the horse, the concept is unclear!

When there is a bearing platform, the top of the pile left 35d is used with the bearing platform tie, so that the bearing platform and the pile as a whole, and then columns, beams of steel anchored into the bearing platform, it is anchored into the pile as reliable.

The longitudinal reinforcement of the grouted end-bearing pile is not the calculated stress tendons, but the structural tendons, and the definition of "anchorage length" is the anchorage length of the tensile reinforcement, so the 35d does not deserve to be called the anchorage length.
