PIPELINE TRENCHING AND LAYING DEVICE |
摘要 |
A pipeline trenching and laying device is disclosed, having a tractor supported portion, a ripper and a pipe feed chute. The tractor supported portion supports the pipe as it passes over the tractor. A plurality of rollers are spaced and elevated in a manner that carefully controls the curvature of the pipe. A ripper, towed behind the tractor by a rigid fried connection, cuts a trench. A pipe feed chute is in turn towed by the ripper. The pipe feed chute provides forward and rearward portions separated by an articulating joint. A following roller, having a winch attached, allows pressure to be put on the pipe to cause it to curve in a manner calculated to pass over the tractor supported portion and through the pipe feed chute without bending excessively or kinking.
