Channel construction machinery is provided with a levelling and material lining application attachment to thus provide a continuous mode of channel construction operation in either the longitudinal or transverse direction of operation with respect to the longitudinal axis of the channel. The levelling and/or lining attachment is provided with at least one shaft which is mounted and driven so as to rotate. The length of the shaft is proportioned to the length of the embankment section to be worked on. Located about the circumference of the shaft are blade-like elements, whose surfaces are directed at an angle to the axis of the shaft. The shafts and angularly directed blades are mounted on implement carriers of the channel construction machine in a manner such that they oscillate by being connected to vibration actuators. The implement carriers, however, attached to the frame of the apparatus are isolated from the vibrations of the vibrator by damping elements. In the preferred embodiment of the invention, the blade-like elements are linked together and fixedly mounted as a helix surrounding the rotating and oscillating shaft.

An apparatus is disclosed for the continuous longitudinal construction for canals. The apparatus performs a series of sequential operations required for the construction of a canal. The apparatus performs planing of the surfaces of the sidewall slopes of the canal and the canal bed followed by a smooth surfacing of the planed surfaces with a suitable planing material. The apparatus during the canal construction adjusts to the angle defined by the opposed sloped walls of the canal and is adapted so that the ground-engaging carriages are held against the sloped walls. In this manner, the heavy bridging structures which, in the prior art, extend from one berm of the canal, across the canal, and to the other berm, are eliminated. In addition, two or more apparatus frames are pivotally connected one behind the other. In this manner, continuous adjusting at the connecting hinge is performed as the canal is constructed according to the varying parameters of the canal.
