ABSTRACT:
The stabilizer comprises an elongate support tube having a split extending generally lengthwise responsive to peripheral compression of the tube to cause contraction of cross-sectional dimension and cause frictional engagement with the surface of a bore in an earth structure for anchoring the tube within the bore. A sleeve located about and fixed to the driven end of the tube provides an impact surface for accepting insertion forces for driving the tube into the bore. A support plate having a hole with cross-sectional dimensions smaller than the cross-sectional dimensions of the bore is positioned relative to the earth structure with the hole substantially aligned with the opening of the bore. The plate hole compresses the tube upon insertion of the tube into the bore through the plate hole, the tube expanding after passage through the plate hole to frictionally engage the surface of the bore in spaced relation to the bore opening.
