ABSTRACT:
A canal paving machine is described. The machine comprises an elongated frame which extends transversely across the canal and which is propelled the length thereof while water continues to flow in the canal. A concrete paver is supported on the frame and is designed to lay concrete on one of the sides of the canal and at least a portion of the bottom of the canal as the frame is moved along the length of the canal. Dam members encircle the concrete paving apparatus to protect it from water flowing in the canal during the paving operation.
