Patent abstract
A strand-like material laying device for an appliance for laying any kind of strand-like material into the ground is disclosed. The strand-like material laying device is designed to lay a more rigid strand-like material such as steel pipes into the ground, and assures that the strand-like material to be laid can smoothly be fed into a trench formed in the ground without risking that a bending radius thereof falls below a minimum allowable bending radius which depends on the type of the strand-like material to be laid. The strand-like material laying device can also be immersed into the ground to form a subterranean trench while being moved in a longitudinal direction.
