Abstract (en)
[origin: JPS5542997A] PURPOSE:In a waterway constructing machine for continuous operation system in the longitudinal direction of the waterway, to ensure that the machine can be suppoted on a graded slant surface instead of on a cliff by rotatably pivoting a running mechanism on a machine frame in intersecting manner relative to the running direction. CONSTITUTION:Wheels 1 and 2 are supported on the slant surface 5a and 5b of waterway cross section which are substantially trapezoid in shape and extending while opposed to each other at an angle 5. A machine frame 6 is provided with a frame portion 6a directed downward in the central region and the bottom region 7, and extended in the longitudinal direction of the waterway. Oscillating arms 8a and 8b are freely foldably and expandably fitted to the frame portion 6a. Joints 9a and 9b can rotate the arms 8a and 9b outward. Piston rods 10a and 10b and hydraulic piston cylinder drive means 11 are pivoted on the arms 8a and 8b, and cylinders 11a and 11b are freely foldably and expandably fitted to the machine frame 6. The machine frame 6 is formed as cantilevers 12a and 12b on one side or both sides of the frame portion 6a.
