Abstract
The disclosure concerns an excavation machine for making a trench into ground including a frame extending along a longitudinal direction, an excavation device disposed under the lower end part of the frame, the excavation machine further including at least a first guide device comprising at least a first guide flap protruding from a first lateral side of the frame outwardly of the frame, and wherein, considered in a plane perpendicular to the longitudinal direction, the first guide flap is inclined relative to the first lateral side.
Claims23
An excavation machine for making a trench in a ground including:
- a frame extending along a longitudinal direction between a lower end part and an upper end part, the frame having a first main side, a second main side opposite to the first main side, a first lateral side and a second lateral side opposite to the first lateral side, the first and second main sides and the first and second lateral sides extending along the longitudinal direction of the frame, the first and second lateral sides being transverse to the first and second main sides;
- an excavation device disposed under the lower end part of the frame;
- wherein said excavation machine further includes at least a first guide device comprising at least a first guide flap protruding from the first lateral side of the frame outwardly of the frame, and wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the first guide flap is inclined relative to the first lateral side.
A method for drilling a ground, comprising:
- providing an excavation machine for making a trench in a ground including:
- a frame extending along a longitudinal direction between a lower end part and an upper end part, the frame having a first main side, a second main side opposite to the first main side, a first lateral side and a second lateral side opposite to the first lateral side, the first and second main sides and the first and second lateral sides extending along the longitudinal direction of the frame, the first and second lateral sides being transverse to the first and second main sides,
- an excavation device disposed under the lower end part of the frame,
- wherein said excavation machine further includes at least a first guide device comprising at least a first guide flap protruding from the first lateral side of the frame outwardly of the frame, and wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the first guide flap is inclined relative to the first lateral side;
- drilling a first trench vertically into the ground, the first trench having a first main face which is vertical as well as a first lateral face which is vertical and orthogonal to the first main face;
- then
- drilling a ground portion vertically drilled into the ground using said excavation machine, the first guide flap bearing against the first main face of the first trench during the drilling of the ground portion.

- an excavation device disposed under the lower end part of the frame,
- wherein said excavation machine further includes at least a first guide device comprising at least a first guide flap protruding from the first lateral side of the frame outwardly of the frame, and wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the first guide flap is inclined relative to the first lateral side, wherein the first guide device further comprises a second guide flap connected to the first guide flap so that the first guide flap is disposed between the frame and the second guide flap, and wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the second guide flap is inclined relative to the first guide flap;
- drilling a first trench vertically into the ground, the first trench having a first main face and a first lateral face which is orthogonal to the first main face;
- then
- drilling a ground portion vertically by using said excavation machine, the second guide flap bearing against one or more of the main face and the first lateral face of the first trench during the drilling of the ground portion.
