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.

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 that includes a plate that protrudes from the first lateral side of the frame outwardly of the frame, said plate being configured to bear against a face of a previously excavated trench in order to keep the frame at a constant distance from said face, thereby preventing a deflection of the excavation device in a horizontal plane, wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the plate of the first guide flap is inclined relative to the first lateral side, and wherein the plate of the first guide flap is mounted on the frame to pivot about a first axis parallel to the longitudinal direction, the first guide device further comprising a first locking device to rotatably lock the plate of the first guide flap relative to the first lateral side to prevent the rotation of said plate relative to said first lateral side, thereby keeping the plate of the first guide flap at a constant inclination relative to the first lateral side of the frame.
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 that includes a plate protruding from the first lateral side of the frame outwardly of the frame, wherein, considered in a plane perpendicular to the longitudinal direction of the frame, the plate of the first guide flap is inclined relative to the first lateral side and wherein said plate is mounted on the frame to pivot about a first axis parallel to the longitudinal direction, the first guide device further comprising a first locking device to rotatably lock the plate of the first guide flap relative to the first lateral side to prevent the rotation of said plate relative to the first lateral side, thereby keeping the plate of the first guide flap at a constant inclination relative to the first lateral side of the frame;
- 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 into the ground using said excavation machine, the plate of the first guide flap bearing against the first main face of the first trench during the drilling of the ground portion in order to keep the frame at a constant distance from said first main face, thereby preventing a deflection of the excavation device in a horizontal plane.
