摘要： The invention relates to an auger for making a borehole that presents in its inside wall a groove that is substantially helical, said auger comprising: a hollow core provided with an outer helical blade; a movable cutter gouge suitable for taking up an active position in which the gouge projects outside the volume defined by the periphery of the blade, and a retracted position in which it is placed inside said volume; and means for displacing said gouge from its retracted position to its active position and comprising an additional member mounted to move in said core in translation and/or in rotation, and placed at the bottom end of said core, together with control means for causing said gouge to be displaced from its retracted position to its active position in response to said additional member moving relative to at least the bottom portion of said hollow core.

摘要： A rotary displacement piling equipment for boring a hole within the soil includes a rotary displacement bit, driving rod members connected to the bit, a casing surrounding the driving rod member, and a casing adapter having a lower end provided with a cylindrical collar for co-operating with the upper part of the casing for keeping in line the casing with respect to the driving rod member and with an horizontal thrust face for applying a thrust at the upper end of the casing, the driving rod member passing through the casing adapter. The equipment may also include a rotary drive box co-operating with the driving rod member for rotating the driving rod means and provided with connecting member to be connected to the upper end of the casing adapter, and vertical supporting and guiding member for supporting and vertically guiding the rotary drive box.
