MILLING HEAD AND METHOD OF MECHANICAL TREATMENT OF PILE CAPS Russian patent published in 2012 - IPC E02D9/00 B28D1/18 

FIELD: construction.

SUBSTANCE: method of mechanical treatment of a cap in a pre-fabricated pile, which comprises a pile core, a pile shaft and metal reinforcement arranged between them, in particular, a milling head, consists in the fact that the core and the shaft of the pile cap are removed simultaneously by means of milling elements, which are rigidly or detachably connected to each other. At the same time the central and the ring cutters of the milling head are equipped with many central cutters, are rigidly connected to each other and arranged coaxially to the longitudinal axis of the drive shaft, central cutters are located in the central circumference, and circular cutters separated from them with the middle circumference, are located in the outer circumference, by means of which the circumferences are located at least approximately perpendicularly and concentrically to the longitudinal axis of the drive shaft.

EFFECT: fast and reliable treatment of a pile cap, without damage of reinforcement arranged in it.
