Definitions
- the present invention relates to the field of the manufacture of trenches in the ground, and more particularly non-rectilinear trenches, in particular curved, ovoid or circular trenches. It finds an application in the manufacture of walls molded in the ground, including curved, ovoid, annular or circular walls.

- a first drilling member which is rotatable about a first axis of rotation
- a first technique consists in using the machine of the document FR 2 211 027 and in making a succession of trenches of transverse sections - said sections being considered in a horizontal plane - rectangular inclined with respect to each other, the inclination being considered in a horizontal plane.
- a disadvantage is that this method does not allow to obtain a precise circular shape.
- This method generally consists in making two primary walls distant from each other and then making a secondary wall connecting the two primary walls previously executed.
- the realization of the secondary wall requires to reform a portion of the primary walls to a certain thickness.
- a first difficulty lies in the fact that the thickness of concrete to be reformed is much greater at inside the curve only outside, which poses problems in maintaining the drilling trajectory.
- a second difficulty lies in the fact that reforging to a large thickness induces overconsumption of energy and consumable cutting tools.
- the document EP 2 553 175 proposes to use a reinforcement cage provided with sacrificial elements disposed on either side of the body of the reinforcement cage.
- a disadvantage of this process lies in particular in the cost of manufacturing specific reinforcement cages.
- An object of the present invention is to provide a drilling machine for producing non-rectilinear walls, for example annular or partially annular, or even accordion or zigzag, avoiding the aforementioned drawbacks.
