Lower feature：
(1) duration is saved.Hammering or static pressure piling technique can be used in steel pipe post stake, one day most soon can 10 left sides of pile
The right side, far more than bored pile construction speed.
(2) environmental pollution is small.Steel pipe pile driving construction need not handle discarded slurry, advantageous to environmental protection.
(3) steel pipe post pile verticality is high.Steel pipe post pile monkey is hit is not necessarily to casting concrete afterwards in place, avoids concrete
Pour the influence to vertical support column verticality.
(4) pile quality is high.Cast-in-situ bored pile is also easy to produce the bad phenomenons such as necking down, broken pile, substantially reduces pile foundation vertical and holds
Power is carried, and uses steel-pipe pile pile quality high, vertical bearing capacity is guaranteed.
