METHOD AND DEVICE TO REMOVE PIPE

摘要

A pipe removal method includes navigating a flexible element through a first pipe. At least a portion of the flexible element is coupled with the first pipe. The flexible element and the first pipe are pulled as a composite assembly, and the flexible element reinforces the tensile strength of the first pipe. In one example, the first pipe is at least pulled in compression between the point of coupling between the flexible element and the first pipe and a proximal end of the flexile element. In another example, the method includes wrapping the composite assembly around a spool. The composite assembly is thereby removed from the ground surrounding the first pipe.

1. A method for pipe removal comprising:
navigating a flexible element through a pipe; coupling at least a portion of the flexible element with the pipe; pulling the flexible element and the pipe as a composite assembly, wherein the flexible element reinforces a tensile strength of the pipe; and removing the composite assembly as a continuous unit from the ground surrounding the pipe.
