6.7. ALTERNATE ANCHORING METHODS IN WET-HOLE
INSTALLATIONS
6.7.1. In wet-hole installations, when Xerxes’ preferred method
of man-out-of-hole anchoring is not available, the following
methods may be used.
6.7.1.1. With both methods, place the hold-down strap between
the wire rope and the tank so that the wire rope is never in direct
contact with the tank.
6.7.1.2. The H-shaped positioning clips around the strap are
designed to accommodate the wire rope on top of the strap
as shown in FIGURE 6-7 and FIGURE 6-8.
6.7.1.3. The following method is
shown in FIGURE 6-7
:
• attach a wire rope to each end of each hold-down strap;
• secure the termination of the wire rope
(See SECTION 6.5.
for suggested method.)
;
• center each hold-down strap on each rib marked with the
arrowhead symbols
;
• place the deadmen on top of the wire ropes on each side of
the tank;
• lower the deadmen to the bottom of the excavation;
• take the slack out of each wire rope and splice the termination
of the wire ropes on top of the tank
(See SECTION 6.5.)

6.5.13. When two clips are required, apply the second clip as
near the loop or thimble as possible.
(See FIGURE 6-4.)
6.5.14. When more than two clips are required, apply the
second clip as near the loop or thimble as possible, turn nuts on
second clip firmly, but do not tighten initially.
(See FIGURE 6-4.)
6.5.15. When more than two clips are required, space additional
clips equally between the first two, take up rope slack, and
tighten nuts on each U-bolt evenly.
6.5.16. Tighten all hardware uniformly and follow the manufac-
turer’s torque specifications. Double-check the tightness once
the anchoring system is complete.
6.5.17. If forming a loop in the wire rope, a splice is required for
connecting the two ends together. Standard rigging practice for
splicing wire rope calls for using twice the number of clips
recommended for a single-end termination. Use a minimum of
four clips for a 3/8-inch wire rope and a minimum of six clips for
a 1/2-inch wire rope. Place the rope ends parallel to each other
and install the clips
as shown in FIGURE 6-5.

6.6. MAN-OUT-OF-HOLE ANCHORING
6.6.1. The Xerxes man-out-of-hole (MOH) strapping system is
designed for use in installations where water is in the excavation
and/or where personnel may not enter the hole because of site
restraints. An MOH strapping system can be, but need not be,
used in conjunction with Xerxes deadmen.
6.6.2. When using the MOH strapping system, the placement of
components is critical.
