Abstract:
A semi-permeable expanding sleeve system for pipe spreading in a borehole is disclosed. The system has an expansion sleeve, a grout injection pipe and a high-solids grout mixture. The expansion sleeve has a top end and a bottom end. The grout injection pipe has a first end, a second end, an inlet and at least one outlet. The grout injection pipe is insertable through the open top end of the expansion sleeve such that the at least one outlet is positionable within the expansion sleeve and the inlet is positionable adjacent the top end of the expansion sleeve. The grout mixture is pumped through the grout injection pipe into the expansion sleeve using a pump. A closing mechanism is provided for closing the expansion sleeve around the grout injection pipe to create a semi-permeable enclosure.

Claim (Index 11):
A method of spreading pipes in a borehole, comprising the steps of:\n providing an expansion sleeve and a grout injection pipe, the expansion sleeve having a top end and a bottom end and the grout injection pipe having a top end, a bottom end, an inlet and at least one outlet; inserting the grout injection pipe into the expansion sleeve through the top end of the expansion sleeve such that the at least one outlet of the grout injection pipe is positioned within the expansion sleeve and the inlet of the grout injection pipe protrudes from the top end of the expansion sleeve; closing the bottom end of the expansion sleeve to create a semi-permeable enclosure; inserting the semi-permeable enclosure into a borehole with pipes to be spread such that the semi-permeable enclosure is positioned in a central location of the borehole relative to the pipes to be spread; pumping a grout mixture through the inlet of the grout injection pipe such that it travels through the outlet of the grout injection pipe into the expansion sleeve causing the expansion sleeve to fill with grout and forcing the pipes outward towards a wall of the borehole as the expansion sleeve expands.
