<p>PURPOSE: To provide a laying device for pipe line free from effect on transport of vehicle, etc., on a road surface and having a high laying efficiency. CONSTITUTION: A laying device of pipe line is composed of a guide rail 3 arranged in the laying direction of a pipe line via each hanging support body 4 on each lining frame 2 for supporting each lining plate 1, trolleys 5 running along the guide rail 3 and a crane 6 for supporting a pipe 8 vertically hung on each 5. Thus, since the pipe 8 is transported and mounted by a pipe line laying device of the abovementioned structure, a large opening can be provided in a place apart from any crossing point and no traffic restriction is applicable to the crossing point. In addition, because of possibility of a large opening, any long pipe can be drawn in and number of butt-welded position of mutual pipes can be small so as to improve efficiency. Furthermore, requirement on meeting point is eliminated so that such labor as digging and back filling may be eliminated.</p> |
