Lateral drilling tool and method from vertical bore hole

摘要

A lateral drilling system includes a device for drilling a first bore hole, preferably vertical or substantially vertical, and including a tool for boring a second bore hole in a direction transverse, preferably normal or substantially normal, to the first bore hole. The vertical boring tool may be any vertical boring device. A casing for the first bore hole may be used. The tool for boring the second bore hole includes a pipe launching section and a pipe receiving section. There is also a removable rack for holding a supply of pipe segments, each segment having a lead end of reduced diameter for fitting into a tail end of a preceding pipe segment, so that the segments form a conduit which may be used to treat surrounding ground. The tool includes a frame for holding the pipe receiving section, pipe launching section and pipe launching mechanism. The pipe launching mechanism includes a pushing arm and a power source to push each pipe segment one by one into the ground. A stabilizing mechanism may also be used to stabilize the device's frame.

1. A tool for boring holes transversely to and inside a first hole, the tool comprising;
(i) a frame; (ii) a pipe launching unit mounted in the frame and having a set of rails for receiving a pipe segment in a pipe launching position; and (iii) a power unit mounted in the frame having a pushing arm for pushing the pipe segment in an axial direction of the pipe segment, wherein the pushing arm moves from a ready position to a final position along a substantial axial direction of the pipe segment in a launching direction.
