Ala. Admin. Code r. 535-X-13-.05 - Soil Classification
The Commission hereby adopts the following soil classifications for the purpose of determining design loads, specifications and holding power of anchors and tiedown devices.
See Table at http://www.alabamaadministrativecode.state.al.us/docs/mfch/McWord13MFCH.pdf
(1) The test probe is a device for measuring
the torque of soils to assist in evaluating the holding capability of the soils
in which the anchor is placed. The test probe has a helix on it. The overall
length of the helical section is 10.75 in.; the major diameter is 1.25 in.; the
minor diameter is 0.81 in.; the pitch is 1.75 in. The shaft must be of suitable
length for anchor depth.
(2) A
measure synonymous with moment of a force when distributed around the shaft of
the test probe.
(3) Below these
values a registered professional engineer should be consulted.
(4) A C4 or C5 anchors that has been approved
by the Commission must be used unless the soil is tested with a soil test probe
or another Commission approved method.
