<p>PURPOSE:To improve working efficiency and prevent the generation of noise pollution by loading a self-running frame with a series of constructing devices necessary for the excavation of channels for burying cables, enclosing the frame outer surface with a sound insulating material, and conducting the work while moving the frame. CONSTITUTION:A self-running frame 2 is loaded with constructing devices such as a road cutter 3, a road breaker 4, a drilling shovel 5, a soil conveyor 6, a sheet piling device 7, a compacting device 9, a sheet pulling device 10 which are necessary for the excavation of channels for burying cables. The outer surface of the self-running frame 2 is enclosed with a sound insulating material. The work is advanced while moving the frame 2, and noise pollution in night work is prevented. Hence, the working efficiency can be improved.</p> |
