DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a method for installing lines, pipes or cables underground, which can be especially efficiently utilized in irrigation, water supplying, water conveyance and geothermal exchange.
BACKGROUND ART
For example, in conventional irrigation or irrigating operations, the watering of the land is effected such that primarily a trench is dug in the ground, then the water supply pipes are installed in the trench and finally the trench is filled up with the soil or earth. As for the installation of cables (e.g. for supply of electricity, for telecommunication) a propulsion method is used. However, such conventional methods have not achieved satisfying results heretofore. For example, the methods involve hard labor of the workers and have suffered an extremely poor efficiency.
Accordingly, it is an object of the present invention to provide a method which can easily and readily install lines, pipes or cables underground irrespective of the purpose and the size thereof.
DISCLOSURE OF INVENTION
Namely, this invention relates to a method for efficiently installing lines, pipes or cables underground. In operation, a boring head 1 which forms an elongated bore underground along with the movement of a boring device 2 is disposed underground. A flat plastic sheet 4 is continuously reeled out and is formed into a rigid plastic tube 5 by a tube forming device. A hauling rope 7 is simultaneously reeled out into the rigid plastic tube 5. Such plastic tube 5 and a hauling rope 7 have their front extremities connected to the rear end of the boring head 1. Subsequently plastic tube 5 is continuously installed underground along with the movement of the boring head 1. Such movement of the boring head 1 also provides for the simultaneous extending of the hauling rope 7 in and along the installed plastic tube 5. The front portion of a desired line, pipe or cable is connected to the tail portion of the extended hauling rope 7. Finally, only the hauling rope 7 is pulled or hauled within and along the stationary plastic tube 5 so as to install the line, pipe or cable in and along the plastic tube 5.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention is described in details hereinafter in conjunction with attached drawings.
In FIG. 1 and FIG. 2, the entire construction of the installing apparatus used for the method of this invention is disclosed. The installing apparatus substantially comprises a boring device 2 which is provided with an elevatable boring head 1 and is moved in any direction on the ground for boring a horizontal hole underground, a hauling machine 3 such as a bulldozer for hauling the boring device 2, a plastic-tube-forming device 6 which forms continuously a plastic tube 5 from a flat plastic sheet 4 disposed behind the boring device 2, a rope supplying device 8 which continuously supplies a hauling rope 7 into the plastic tube 5 and a connecting means 9 which connects the front extremities of the plastic tube 5 and the hauling rope 7 to the rear end of the boring head 1.
In FIG. 2 and FIG. 4, the construction of the plastic-tube-forming device 6 and of the rope supplying device 8 is shown in detail.
Referring to the plastic-tube-forming device, a spool of flat plastic sheet 4 is preferably supported on vertical support struts 17 by placing a support shaft 15 in a groove 16 formed on the struts 17, which in turn are mounted on a frame structure 13. This frame structure 13 is firmly mounted on the lower ground by
