Abstract A multi-head piling machine for one-step formation of wall has a power box, which is linked via drive mechanism to several hollow drill rods arranged linearly. Each drill rod has a slide sleeve. All the slide sleeves are fixed to a same constraint device. The drill bits of adjacent drill rods are longitudinally staggered. Its advantages include high efficiency increased by more than one time, high pile depth (30m), minimal wall thickness, and one-step formation of unit wall.
