Abstract

A lateral boring device for effective utility installation under sidewalks, driveways, and other obstacles. The present invention utilizes a hand-held drill, a flexible shaft, a blade attachable to the flexible shaft, and a metal sock. The operator of the present invention makes an incision into the ground with the blade in close proximity to the obstacle intended to be circumvented. The operator commences boring, and the flexible shaft begins to descend below the ground and underneath the obstacle. The low power of the drill prevents the flexible shaft from continuing to descend below the hardpan, and cause the flexible shaft to bend in a generally upwardly horizontal direction. The low power of the drill also prevents the flexible shaft or the blade from causing damage to the underside of the obstacle, and eventually the flexible shaft resurfaces on the opposite side of the obstacle. Upon resurfacing, the operator removes the blade and attaches the sock, which can be coupled to the length of wire, pipe or conduit and pulled back through the bore hole.

Description

BACKGROUND OF INVENTION

[0001] Typically wire, cabling, pipe and other equipment installed for providing power, signal, water, or some other medium are placed underground. The reasons for this are to protect and insulate the medium passing through this equipment, and also to eliminate the unpleasing aesthetic appearance of the multitude of these wires, cables and pipes necessary to provide buildings with the necessary utilities and services.

[0002] One prior method for placing these types of underground equipment was to dig a trench along the path desired to place the equipment. The equipment could be placed in the bottom of the trench and covered up. One disadvantage of this method was the damage to the land caused by the trenching. Another disadvantage is the damage to permanent structures in the path of the equipment, such as sidewalks, driveways, highways and other surfaces.

[0003] Currently there are a variety of boring methods for alleviating the disadvantages inherent with tr...

Embodiment Construction

[0015] The present invention provides a tool capable of laterally boring for the placement of underground cables, wires, pipe and other equipment. Referring in more detail to the drawings, as shown in FIGS. 1-5, a preferred embodiment of the present invention is described. It is to be expressly understood that this exemplary embodiment is provided for descriptive purposes only and is not meant to unduly limit the scope of the present inventive concept. Other embodiments, and variations of the hand-held drive assembly or flexible shaft of the present invention are considered within the present inventive concept as set forth in the claims herein. For explanatory purposes only, the apparatus of the preferred embodiments are discussed primarily for the purposes of understanding the method of underground boring. It is to be expressly understood that other boring equipment are contemplated for use with the present invention as well.

[0016] A preferred embodiment of the present invention i...
