184.108.40.206 Performance* The auger shall bore holes in soil in accordance with
table 1. All vertical holes shall be bored to a depth as specified in table I.
All angle holes shall be bored to the depth that results when the auger bar is
extended the same distance that it was extended to drill the vertical holes.
Inability to bore holes to the depth and diameter as specified in table I;
inability to bore holes at angles of 10 degrees, 23 degrees, 30 degrees, or 60
degrees as specified above; inabilty to bore vertical holes with the 16-inch bit
at an average rate of 5 feet in 85 seconds; inability to clear spoil from the
auger bits and remove the spoil so that it does not fall back into the hole;
evidence of breakage, permanent deformation, leakage of hydraulic oil, or
evidence that the replaceable points or cutting edges of the bits are not
highly-wear resistant shall constitute failure of this test.
4.6.2*4 Down pressure. Operate the auger to apply a downward force of not
less than 6,000 pounds. This test shall be repeated 15 times. Inability to
apply a downward force of not less than 6,000 pounds each time or evidence of
any structural failure of the auger assembly (including skids) shall constitute
failure of this test.
220.127.116.11 Pull. With the auger bit anchored to the ground, place the boring
bar control in the raised position and operate to exert not less than 5,000
pounds raising effort at the boring bar. Inability to exert not less than 5,000
pounds raising effort or evidence of any structural failure of the auger
assembly (including skids) shall constitute failure of this test.
