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.

A counterweight mounting device, which is installed on a frame supporting a counterweight according to an aspect of the present invention, includes a first link of which a lower end is coupled to the frame so that the first link is rotatable about a first hinge shaft, a second link including a slot guide into which a second hinge shaft coupled to an upper end of the first link is inserted and in which the second hinge shaft slides, a hydraulic cylinder of which a lower end is coupled to the frame so that the hydraulic cylinder is rotatable about a cylinder rotation shaft and an upper end is coupled to the second hinge shaft and rotates the first link, and a connection member installed on an upper end of the second link and connected to the counterweight.

The invention relates to a method and a device for producing a foundation element in the ground, wherein a hole is formed in the ground which is filled with a hardenable filling mass in order to form the foundation element. According to the invention provision is made in that prior to the hardening of the filling mass a data carrier is introduced into the hole, on which information on the produced foundation element is stored .

The invention relates to a trench cutter and a method for producing a cut trench in the soil having a cutter frame, at least one pair of cutting wheels which are supported and driven in a rotatable manner on a lower end of the cutter frame, wherein each cutting wheel has a plurality of cutting teeth along its outer circumference, and a supply and/or discharge means for supplying or discharging a cutting liquid to or from the cut trench in the region of the cutting wheels. According to the invention provision is made in that spaced from the supply and/or discharge means a cleaning device is provided for cleaning the cutting wheels during the cutting operation with a cleaning fluid and in that the cleaning device has a plurality of cleaning nozzles which are directed onto the outer circumference of at least one cutting wheel and designed to inject the cleaning fluid to loosen adhering soil material.
