2. Friction pile means that its bearing capacity is completed by the friction between the pile body buried in the soil and the soil, so it is called friction pile. The length of the pile driven into the soil must meet the design requirements.
3. End-bearing pile means that the pile end must fall on the bearing layer of soil, that is, the upper load is transferred from the pile end to the bearing layer, so it is called end-bearing pile.
To sum up, the construction machinery for friction piles and end-bearing piles can choose static pressure piles and hammering piles, which is something to be considered in the construction scheme or construction. The choice of friction pile or end-bearing pile for a project is a matter for structural designers to choose according to the conditions such as address exploration report, structural form and structural scheme, which is considered in design.
