ROCK INJECTOR STATIC LOAD TEST
Purpose of test: The purpose of the test was to determine the static load
which the Titus HPP-R-12-HD Rock Injector could withstand without deformation, cracking, or bending.
Date: November 13, 2007
Location: Bermingham Foundation Solutions test facilities, Hamilton Ontario
Witnesses: Gord Williams – Titus Steel Co
Troy Smith – Bermingham Foundation Soloution
Jim Farquharson – Trow Associates Inc.
Procedure: The Titus HPP-R-12-HD was welded to a standard 12” “H” pile and place in a 400 ton flat press. Pressure on the press was gradually increased to 340 tons with no distortion on the Rock injector.
At 340 tons the press exhibited significant signs of stress on the bed and pins and the test was terminated.
Visual Observations: The Rock injector was removed from the bed and visually inspected by all observers and there were no signs of distortion, cracking. The rust prevention paint did show some minor flaking or peeling. The rock injector was then sandblasted and examined. No evidence of distortion or cracking was detected.
Conclusions: All observers agreed that the Titus Rock Injector easily reached the 340 tons of load and the consensus was that the loading would have passed 400 tons had the press not evidenced signs of fatigue. |
