摘要
The invention relates to civil engineering work. …??It is concerned with a device for producing piles cast in the ground, the auger of which consists of a conventional lower part (1) and of an upper part comprising a hollow inner element (4) and a removable outer element (10) in the form of an auger, having a longitudinal discontinuity making it possible to engage it on the hollow inner element (4). The hollow inner element (4) can extend fixedly in the elongation of the lower part of the auger (1) or be mounted telescopically in the latter. …??This is used for producing cast piles of great length with equipment of reduced dimensions. …IMAGE…
