Abstract
A device for forming cast-in-situ piles in civil engineering work includes an auger which consists of a conventional lower part and an upper part comprising a hollow inner element and a removable outer element in the form of an auger having a longitudinal discontinuity which enables it to be fitted over the hollow inner element. The hollow inner element may extend, fixedly, as an elongation of the lower part of the auger or be mounted telescopically in the latter.
