Pile foundation engineering can be divided into several types according to construction methods.

Pile foundation engineering can be divided into precast pile and cast-in-place pile according to construction methods.

Precast piles are driven into the ground by pile drivers.

Precast piles have the advantages of saving materials and high strength, and are suitable for buildings with high requirements; Its disadvantage is that the construction is difficult and the construction time is long due to the limitation of the number of machines.

For cast-in-place piles, firstly, drill holes at the construction site, and after reaching the required depth, put steel bars into the poured concrete.

The advantage of cast-in-place pile is low construction difficulty, especially manual digging pile, which can be constructed at the same time without the limitation of mechanical quantity, greatly saving time; Its disadvantages are low bearing capacity and high material consumption.
