Abstract
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.
