Floor is the floorboard of all kinds of floors, which means that floors will show certain decorative effects and similar functions through some specific tools and materials combined with appropriate construction technology. Such as epoxy self-leveling floor, emery durable floor, ultra-flat floor, epoxy terrazzo floor,
Epoxy colored sand floor, epoxy antistatic floor, epoxy damping floor, polyurea anticorrosive floor, garage ramp floor, polyurethane floor, stadium PU floor, concrete seal curing agent, etc. Terraced fields have been widely used in various fields since they were introduced into China 10.

1, classified by carrying characters
Friction pile: in the ultimate bearing capacity state, the vertical load on the top of the pile is borne by the side resistance of the pile, and the resistance at the end of the pile can be ignored.
End-bearing friction pile: in the ultimate bearing capacity state, the vertical load on the top of the pile is mainly borne by the side resistance of the pile.
2. End bearing piles
End-bearing pile: in the ultimate bearing capacity state, the vertical load on the top of the pile is completely borne by the resistance at the end of the pile, and the side resistance of the pile can be ignored.
Friction end bearing pile: in the ultimate bearing capacity state, most of the vertical load on the pile top is borne by the resistance at the pile end.
Because there are great differences in bearing capacity and load transfer between friction piles and end-bearing piles, the settlement of friction piles is usually greater than that of end-bearing piles, which will lead to uneven settlement of piers and abutments. Therefore, friction piles and end-bearing piles should not be used at the same time in the same pile foundation.
